On this page, 'Sonic the Hedgehog' games will be given a general overview on what happens in them. Sonic and Shadow moments that can be considered Sonadow will be mentioned here as well.
== Mainline Games ==
=== Sonic Adventure 2 ===
==== Overview ====
Sonic Adventure 2 was made in celebration of Sonic's 10th anniversary. It was released in 2001 on June 18 for America and June 23 for Japan and Europe. Sonic Adventure 2 is the first game Shadow appears in. This game was created in America by a Japanese team from Sonic Team who traveled to America to make its creation. Many well known Sonic Team members today helped with its creation, such as Takashi Iizuka, Eitaro Toyoda and Kazuyuki Hoshino. The game is heavily inspired by America where many places resemble places in said country like San Francisco. There are two versions of this game: the original Dreamcast version and the Game Cube version. A DLC for the game called Sonic Adventure 2: Battle was added in later 2001 in Japan and early 2002 in America.
It was thought that Shadow would only appear in this game, but due to how much the fans loved him, SEGA/Sonic Team decided to bring him back for their next game, Sonic Heroes.
==== Summary ====
341x341px|thumb|Dreamcast version of a Sonic Adventure 2 playthrough by RickyC
Eggman stumbles across his grandfather Gerald's notes on a project he worked on called Project: Shadow. Hungry for the power it was said to contain, Eggman breaks into G.U.N.'s facilities to release Shadow from his stasis that he had been trapped in for 50 years. Once awakened, Shadow thanks Eggman and says that he would grant any wish he wants. Later, it is known that Shadow lied to Eggman and was using him to collect the Chaos Emeralds to power the Eclipse Canon on the ARK to kill all of humanity for Gerald's revenge. Eggman first gets confused thinking that Shadow is Sonic due to their resemblance, but Shadow corrects him by saying his name is Shadow. After he is released, Eggman sends Shadow out to collect the Chaos Emeralds after figuring out their locations, which causes Sonic to get falsely accused of stealing the Chaos Emeralds due to their resemblance. Due to the misunderstanding, G.U.N. arrests Sonic and chases after him when he tries to escape.
It is later shown that Shadow's memories had been manipulated by Gerald in order for him to enact Gerald's revenge to humanity. Gerald wanted revenge towards humanity for killing his granddaughter, Maria, unjustly. Maria was someone very close to Shadow where he saw her as his sister despite not being related. Shadow was created by Gerald due to the military desiring an ultimate weapon. Maria was shot and killed while trying to help Shadow escape G.U.N. who forced their way into the ARK to shut down Project: Shadow. G.U.N. tried to shut down Project: Shadow, the Ultimate Lifeform, in fear of the power it held and killed many scientist and Maria in the process.Eggman threatens the whole world by shooting a not fully powered ARK cannon at the moon, which results in blasting it in half. His threat, however, falls on deaf ears. Shadow suggests that the full power of the cannon is needed and in order to do that, they need all of the Chaos Emeralds. While this is happening, Sonic and company find out what Eggman is up to and fly up to the ARK using Eggman's rocket to stop his plan.
When all of the Chaos Emeralds were collected, the system was overridden by Gerald's commands. In order to stop the ARK from crashing into the Earth, Sonic and company had to team up with Eggman and Rouge. Though they were able to stop the Chaos Emeralds, they weren't able to stop the ARK from a headlong course into destroying the world. Remembering his actual promise to Maria, Shadow decides to help. Sonic and Shadow save the day by defeating the Bio-Lizard and Chaos Controlling the ARK back to a stable spot. In the process, Shadow falls to the world, hoping that he fulfilled Maria's wish. Sonic came back alone to the ARK, sorrowful, in thought and admiration. Everyone else also contemplated upon the events that had just happened. In the end, Sonic waved good bye to Shadow, believing that that was the last time he was going to see him.
==== Sonadow Moments ====
(Note: The following dialogue scene moments are from the English dialogue. The original Japanese dialogue scenes at times, contain different wording.)
On the Dreamcast version of Sonic Adventure 2, the Start screen is of Sonic and Shadow with the World and Moon shown behind them. This is the first time that the Moon and the World symbols are seen for them together.
left|thumb|263x263px|Sonic Adventure 2: Battle opening sequence
In the opening cutscene shown when you open Sonic Adventure 2: Battle, a scene where Sonic and Shadow crosses paths in front of the moon is shown. If you look at their position, you can faintly make out a heart from the outline of their bodies.
Sonic first meets Shadow after running away from the military. Shadow had broke into a bank to steal a Chaos Emerald which caused the military to mistake him for Sonic. Sonic slowly turns his head before exclaiming, "What?" and sees Shadow standing on a downed military robot with the Chaos Emerald. Shadow says, "It all starts with this. A jewel containing the ultimate power..." Sonic shouts, "That's the...Chaos Emerald!" and tilts his head in thought. He realizes that the military went after him due to Shadow and says, "Now I know what's going on!." This catches Shadow's attention and he widens his eyes for a split second. Sonic then says, "The military has mistaken me for the likes of you!" Sonic questions where did Shadow think he was going with that Emerald as Shadow stared at him. Sonic says, "Say something! You fake hedgehog!" as he starts running after him. Shadow tosses the emerald, grabs it, and shouts, "Chaos Control!" He teleports to the side of Sonic, eying him as he passes him. Sonic, at first, in amazement thinks that Shadow is fast, but then realizes that he was using the Emerald to warp. Shadow proclaims "My name is Shadow," to Sonic while tossing the Emerald in his hand and says that he's the world's ultimate lifeform. After saying that there was no time for games and farewell, Shadow warps away. Sonic flinches as he shields his eyes from the bright light and wonders who Shadow is. When the light clears, Sonic sees that he's surrounded again by the military and says, "Not again!"
When Sonic gets locked up on Prison Island, Tails goes to rescue him. Tails finds Amy already on the island also trying to look for and help him. Amy finds the impatient Sonic that was tapping his foot first, which surprises him. Sonic wonders how she got here and she answers that she got a ride from Tails. She also asks if he is sure if he doesn't need her help and that it looks like he needs it. Sonic says as he warms up, "The reason I'm in here is because of that fake hedgehog!" Amy questions if he means "that black hedgehog." Sonic turns to face her immediately when she mentions him and replies in eager interest, "Did you see it? Where is it now?" Amy says that she'll tell him if he marries her, in which Sonic turns away uninterested and answers, "No way!" Amy thought she had him this time, but frees him anyway. She explains that Shadow arrived with Dr. Eggman. When she mentions Shadow again, Sonic jumps in surprise and interest. Sonic says as he waves his hands, "So, Eggman's behind this, huh?" Amy starts to ask about the writings on the wall inside the cell, but turns and realizes that Sonic had already gone. She calls for him to wait for her and says that he's such a brat sometimes.
As Shadow is running through the jungle in a rush to save Rouge before the island explodes, Sonic happens to see him and says, "Hey that's..." In response, Shadow says, "That blue hedgehog again, of all places..." Sonic shouts, "I found you, faker!" Shadow says back, "Faker? I think you're the fake hedgehog around here. You're comparing yourself to me...ha! You're not even good enough to be my fake." Sonic rushes forward as Shadow says this and shouts, "I'll make you eat those words!" When the fight starts, Shadow says "There's no time to play games, you won't even get the chance!" If you're playing as Shadow, Sonic says "You can't get away this time! There's only one real Sonic!" After the intense fight, they breathe heavily, staring down at each other. Eggman contacts Shadow and asked what he was doing for if he didn't hurry up, the island will blow up with him on it. Sonic overhears this and exclaims, "Blows up??" Shadow gasps, jumps back, and runs off (or furrows his brows and runs off if it's the Dark path). Sonic says that he has to get out of there and find his friends fast. He, too, goes his own way.
* This scene is the last time ever that Sonic calls Shadow a faker and the last time ever that Shadow calls Sonic a fake in an actual canon game. However, Shadow does tease Sonic by calling him a faker in Lego Dimensions, but nowhere else in video game medias. They also call each other faker in the Archie comic series.
When Sonic is launched into space by Eggman in the capsule and seemingly explodes with it, Shadow states, "I guess he was just a regular hedgehog, after all," disappointed for he had high hopes in him and had come to respect him.
Eggman realizes that someone is heading to the Eclipse Cannon so he tells Shadow to go stop whoever it is. He finds Sonic standing there on the way. He approaches him and says, "You never cease to amaze me blue hedgehog. I thought that capsule you were in exploded in space." Sonic replies as they begin to walk, "You know, what can I say...I die hard! You actually saved me, you know." Sonic shows him the fake emerald as he says this. Shadow replies in surprise, "It was a Chaos Emerald, wasn't it? But, there's no way you could have activated the Chaos Control using an Emerald that's fake. So, there's more to you than just looking like me. What are you anyway?" Sonic replies, "What you see is what you get! Just a guy that loves adventure! I'm Sonic the Hedgehog!" Shadow then says, "I see. But you know, I can't let you live. Your adventuring days are coming to an end." Sonic and Shadow rush forward, ready to fight each other. (On the Dark path, Sonic omits saying that Shadow saved him and showing the emerald. Shadow also omits his comment about it.) The two fight and both can use Chaos Control (Which ever path you are on will determine who uses it). (On the Hero's path, when Sonic defeats Shadow, he says, "Game over, Shadow!" While Shadow says, "I'm the ultimate life..." On the Dark path, Shadow says when he wins, "I told you, I'm the ultimate. While Sonic says, "Shoot...I failed.")
When the ARK is on a collision course towards the World, Eggman approaches everyone (except Shadow for he is not present) and hands them Gerald's diary on a disc to read. From this, Sonic hears about some of Shadow's backstory/history which includes Maria's passing, that Shadow was created, and how Gerald had made it so that Shadow will enact revenge on his behalf.
After Shadow remembers his true promise to Maria, he rushes off to help. When the Bio Lizard awakens, Shadow walks up to Sonic and Knuckles and states, "Leave this one to me!" Sonic gasps in surprise and in wonder, asks, "Shadow, what are you doing?" Shadow replies with urgency, "I'll take care of this, while you run to get the Chaos Emeralds!"
Sonic and Knuckles rush to place the Master Emerald. Although Knuckles calmed the emeralds through the Master Emerald, the Bio Lizard gets back up despite being defeated by Shadow. It Chaos Controls out of there and merges with the ARK. Because of this, the ARK still remains on the collision path towards the world. Knuckles calls out to Sonic for him to do something. Sonic glances at Knuckles and then looks at Shadow. Shadow gazes back and nods in understanding. Knuckles makes a face of wonder as he tilts his head.
Sonic and Shadow face each other with their hand up and draw in the Chaos Emeralds. The Emeralds answer their call and they manifest their power to turn into Super Sonic and Super Shadow.
Super Sonic and Super Shadow face off the Bio Lizard together, taking turns (Example of a playthrough fight). While fighting the final boss, the theme song, Live and Learn, plays. While fighting this boss, many interaction lines between Sonic and Shadow occur. Here is what they can say:
Sonic:
* "Shadow are you okay?"
* "Shadow you need rest, let me give it a try."
* "Shadow your power is getting weaker, are you ok?"
* "Shadow! How's your ring energy?" 
* "Before you are depleted, make sure to change places with me to collect more rings."
* "Shadow! at this rate, your Super form won't last. Get back to the colony."
* "Shadow let me collect rings, keep him busy for a while."
* "Shadow! your power is getting weaker! Hey are you ok?"
* "It's up to you, Shadow!"
* "Shadow! Continuous use of your Super form will cause you to disappear! Get back to the colony!"
* "We almost got it!"
* "Shadow I understand, you're unstoppable. Let’s destroy this creature now! Everyone is waiting for us back on Earth."
* "Shadow switch places with me, you're out of rings!"
* "Shadow, you're out of rings!" 
* "Shadow! You're almost out of rings!"
* "Yeah! Take that you creep! Shadow, are you okay?"
Shadow:
* "Sonic leave it to me, I'll destroy it."
* "How are you doing, Sonic?"
* "I'll collect the rings, now it's up to you, Sonic."
* "All right, this is working! Sonic, how are you doing?"
* "Sonic! Leave it to me! I'll destroy him!"
* "The red swelling may be a weak spot...Sonic aim for it!"
* "Sonic what are you doing? You're almost out of rings. Switch places with me."
* "It's up to you Sonic!"
* "Sonic I can't keep this up, hurry!"
* "Hahaha Sonic! I think I've discovered what the ultimate life form is, it might be you!" 
After Sonic and Shadow defeat the Bio Lizard, they clasp hands in victory and nod to each other.
Sonic and Shadow face the ARK to stop it from harming the World. Sonic shouts, "No way that's getting through!" Shadow then hears Maria's voice say, "Shadow, I beg of you..." Shadow in response, says her name. The voice continues, "...give them a chance to be happy." Sonic calls out, "Now Shadow!" They both shout "Chaos Control!" and warp the ARK. Shadow falls to the world as he says, "Maria...this is what you wanted, right? This is my promise I made to you." The ARK warps to a safe spot and everyone celebrates in relief on Earth. 
* The news sign queue text in the cutscene says, "Heroic team work, Sonic and Shadow save the day."
* According to X Takeover #5, before Shadow fell to the World, Sonic tried desperately to save Shadow. However, Shadow waved him away so that Sonic wouldn't fall with him. (Takeover #5 was a joint session between America and Japan, so you can take this as canon. You can hear the question here.)
Sonic comes back to the ARK without Shadow. Rouge asks where is he. Sonic somberly shakes his head. The scene shifts to Sonic giving Rouge one of Shadow’s limiters. She asks him if Shadow was really a weapon to destroy the earth. As she asks this, Sonic stares at his hand that had clasped Shadow’s. Sonic replies, "He was what he was, a brave and heroic hedgehog who gave his life to save this planet, Shadow the Hedgehog." Rouge replies, "I guess you're right," as Sonic clenches the same hand. A bit later, Sonic is alone thinking to himself as he says, “Created, the ultimate life form…” and clenches his fist. Amy walks in and asks what’s the matter. Sonic says, “Oh, it’s nothing. C'mon, let's go home to the planet that is as cool and blue as me!” Amy leaves and Sonic trails after. Before leaving, Sonic looks back and says in a soft voice as he waves, “Sayonara, Shadow the Hedgehog.” The credits roll and Live and Learn plays.
At the very end, a picture of Shadow in front of the World is shown. (A symbolization to show that Shadow is the World. You can read more about it here.) 
Chao Garden
In Sonic Adventure 2, you can take care of Chao in between stages or when you go to the garden yourself when selecting a stage. There are three Chao Gardens available themed after: Heaven, Earth and Hell. In these gardens, Heroes or Dark Characters can alternate in taking care of the same Chao. These characters include Sonic, Tails and Knuckles as Heroes and Shadow, Rouge and Eggman as Dark Characters. There are three types of alignments for Chao: Hero, Neutral and Dark. If a Hero character takes care of a Chao more, it will become a Hero Chao. If a Dark Character takes care of a Chao more, it will turn into a Dark Chao. If both a Hero and a Dark Character take care of a Chao while alternating equally, it will turn into a Neutral Chao.
While taking care of your Chao, four different kinds of Chaos Drives can be given to it to make it better in one of these categories: Swim (Yellow), Fly (Purple), Run (Green) and Power (Red). Animals collected from stages and given to the Chao can also boost up these stats, but it will boost up more than just one stat at a time and the Chao will also gain an animal part from whatever animal it is given. If you give a Chao more of one type of Chaos Drive or animal than another, it can turn into a Swim, Fly, Run or Power Chao. Each alignment has its own version for each category and a normal version that is achieved by keeping all stats the same.
Among the Chao you can create, you can create a Neutral Run-Run Chao that resembles Sonic and a Dark Run-Run Chao that resembles Shadow. These two are part of the three Unofficial Character Chao that you can create. Since the Neutral Run-Run Chao and Dark Run-Run Chao aren't immortal like the other Official Character Themed Chao (Ex. Tails, Knuckles and Amy Rose) and Chaos Chao, they can mate/breed with each other. The animation for mating occurs when two Chao are in their mating season or when one is close to mating season and is willing to mate with a Chao that is in mating season. To activate it manually, you would pick up a Chao that is willing to mate and put them into the circle of flowers of a Chao in mating season waiting for a mate to mate with. Once that is done, if they are willing to mate with each other, the mating animation will occur. In this animation, both Chao kiss/nuzzle each other while music plays in the background. After a bit, a Chao egg will appear from between the two Chao in the circle of flowers.
Both Chao can also participate in little activities with each other while in the garden. If one Chao is doing an activity learned from class, such as playing the trumpet, it is possible to take one of the other Chao and put it next to the performing Chao to have it react. The Chao that is put next to the performing Chao can either join in by playing its own instrument that it learned from class or it can sit down and enjoy the performing Chao's performance by nodding its head to the rhythm. If a Chao decides to do the second option, it will clap for the performing Chao once it is done performing. Activities that can activate this type of reaction are: playing an instrument, exercising, dancing and singing.
Two Player Mode
In Sonic Adventure 2, there is a two player mode where you can play against a friend with characters in the game. In two of the minigame selections, you can play as both Sonic and Shadow to have a friendly competition against each other. The first selection is called "Action Race Battle" where you race against a friend in stages from the Sonic Adventure 2 game. The second selection is called "Kart Race" where you and a friend race against computers in go-karts.
In Action Race Battle, you can choose to either play as Sonic, Shadow, Metal Sonic or Amy Rose. Several stages can be chosen from that range from level 1 to level 4. One such stage called Downtown Race, is based off of the first level you play in Sonic Adventure 2 where Sonic uses a piece of metal to "snowboard" through the city. In this level, the characters chosen get a real board to use to slide down the slopes through the city. Whoever reaches the end first wins. When choosing a character to play as, small descriptions for the character are given to give a summary of what makes that character special or unique compared to the other options. For Sonic it says, "Supersonic Hedgehog. Speed increase 20 rings, attack with 40 rings and stop time with 60 rings." For Shadow it says, "Ultimate life form made by Professor Gerald. Speed and attacks are identical to Sonic." Both Sonic and Shadow are rated 5 stars while Metal Sonic is 4 and Amy Rose is 3. Sonic and Shadow are identical to each other and hold the same speed, power and abilities.
The options for the stages you can select are:
Level 1
* Downtown Race
* Grind Race
Level 2
* City Escape
* Metal Harbor
* White Jungle
Level 3
* Green Forest
* Sky Rail
* Radical Highway
Level 4
* Final Rush
* Final Chase
In Kart Race, several characters can be chosen to play as. The characters available are the ones you can play in the Sonic Adventure 2 game. Those characters are: Sonic, Shadow, Tails, Eggman, Knuckles and Rouge. In this minigame, you and a friend will race against the computers of the characters that weren't chosen. There are three difficulties of races: Beginner, Standard and Expert.
Other minigame selections for two player mode are: Treasure Hunt Race, Shooting Battle, Chao Race and Chao Karate. In Treasure Hunt Race, you can play as either Knuckles, Rouge, Tikal or Chaos in a race to find the Master Emerald the fastest. In Shooting Battle, you can play as either Tails, Eggman, Chao or Dark Chao as you fight each other in a battle to deplete the opponent's heath bar.
In Chao Race and Chao Karate, you can compete against a friend using the Chao you have in the game in your Chao Garden. In these minigames, you can use a Sonic and Shadow Chao to compete against each other in either a race or karate battle. Since there is only an option for two players, only two Chao will be used in either minigame selected.
=== Sonic Heroes ===
===== Overview =====
This game was released on December 30, 2003 in Japan and on January 5, 2004 in America. It was in this game that due to Shadow's popular demand, he was brought back after seemingly dying in Sonic Adventure 2's ending.
===== Summary =====
thumb|261x261px|A playthrough of Sonic Heroes by FCPlaythroughs
Sonic Heroes follows the story of Team Sonic (Sonic, Knuckles, Tails), Team Dark (Shadow, Omega, Rouge), Team Rose (Amy, Cream, Big), and Team Chaotix (Vector, Espio, Charmy). They each have separate stories, but they intertwine with each other and converge at the end.
Team Sonic's story begins with Tails handing Sonic an invitation from Eggman. Eggman claims that he is going to destroy the world in three days. Sonic says that it sounds like a party and decides to go after Eggman to stop him. Knuckles and Tails follow along with him. They pursue Eggman and along the way, they meet some of the other team members and fight with them for various reasons.
Team Dark's story begins with Rouge trying to find Eggman's treasure. She finds a location where Shadow and Omega are stored. She frees Shadow, causing Omega to awaken and attack. Shadow saves Rouge and is about to attack Omega back when Rouge stops them. She finds out that Omega is angry at Eggman for being held captive there and that Shadow doesn't remember anything. She enforces that it's settled and that they are now a team, forcing them to join hands. They pursue Eggman for different reasons. Shadow wants to know answers about himself and of what is going on. Omega wants revenge and Rouge wants treasure. They, too, run into different team members and fight them for various reasons. Throughout the story, Shadow wonders if he is an android because of a destroyed robot Shadow they found. After defeating the last Eggman boss, Rouge and Omega find a room filled with robot Shadows. Omega is left with them to destroy and hints that the one outside was the real one. Rouge then tells Shadow that she thinks that she'll go bother Knuckles. Shadow says that some things never change.Team Rose's story starts with Amy staring at a newspaper with Sonic, Chocola the Chao, and Froggy. She almost loses this paper to the wind, but Cream catches it and tells Amy to be more careful. The newspaper is the clue to finding what each member of Team Rose is looking for. Amy is looking for Sonic, Cream is looking for Chocola, and Big is looking for Froggy. Amy tells them not to worry and that there is no time to waste. She rudely pushes past Big, almost making him fall into the water. They then begin their adventure. They also run into other team members along the way and fight them for various reasons. After defeating the Eggman boss, they find their respective friends. Cream points out that Sonic was present, which causes Amy to chase after him, making him run away.
Team Chaotix's story begins when Charmy comes into their office with a mysterious package. In the mysterious package is a walkie-talkie. A mysterious voice comes from it saying that he has heard of their skill and requires them. Espio finds it suspicious, but Vector says that they don't refuse jobs that pay and insist that they take it. Throughout the story, they listen to the voice's instructions as he gives them missions to complete. They run into and fight other team members too. At the end, they figure out that the client is Eggman and they get mad at him for not paying them.When everyone is together, Metal Sonic, who had been copying all their data, transforms into Metal Overlord. Eggman says that only the Chaos Emeralds can stop him, but after seeing that all of the teams together had all seven Chaos Emeralds, he then says that even though they have all the Chaos Emeralds that it might still not be enough. Though even after hearing what Eggman had to say, everyone doesn't give up hope and decides to work together to beat Metal Overlord. Team Rose, Team Chaotix, and Team Dark whittle down Metal Overlord's health while Team Sonic takes him down completely with Super Sonic, making Metal Overlord revert back into Metal Sonic.
===== Sonadow Moments =====
(Note: The following dialogue scene moments are from the English dialogue. The original Japanese dialogue scenes at times, contain different wording.)
On the Story selection screen, Sonic is next to Shadow in their respective teams.
In Lost Jungle, Team Sonic runs into Team Dark. Shadow, with no recollection of his memories, says, “Look, it’s that hedgehog…” Rouge says she wonders what they were up to and bets that they will get in her way and make trouble. Knuckles says, “Hey, isn’t that…” Tails points at them and calls out Sonic’s name. Sonic says, “Talk about being stubborn and full of surprises…” Rouge says that it’s too bad that they had to come all that way for nothing and that they will take it from there. Knuckles says, “What did you say?” Omega says that it’s locked on Eggman and non-compliant intruders will be destroyed. Sonic replies, “Hmm, didn’t you know? We have a date with Eggman too.” Shadow replies smug, “Is that so…well then, it will be a date to DIE for!” Sonic says, “Hey that’s my line!” and lunges. Shadow smirks and lunges as well.
* In the Japanese version, Rouge says that Team Sonic will meet trouble if they continue, so it’s implied that they tried to stop them so that they won’t get hurt later.
At the start of the boss fight with Team Dark, Shadow asks, “What’s with that hedgehog that looks like my twin?” Sonic during the fight questions, “Not the best way to greet those you haven’t seen in a while?” At the end of the fight, Sonic says, “Hey guys, chill out.”
In the Last Story before facing Metal Madness, the teams give Sonic their Chaos Emeralds in order to defeat Metal Sonic. Shadow says to Sonic and his team, “Okay guys, we’ll buy you some time. That way you can use your super powers.” The rest of the teams agree with this plan.
After Team Dark's turn of stalling Metal Sonic, Shadow says to Sonic, "Sonic, we’re counting on you!”
=== Shadow the Hedgehog (2005) ===
==== Overview ====
Shadow the Hedgehog is a game that was released on November 15, 2005 in American and December 15, 2005 in Japan. This was the last game that was developed by SEGA Studios USA, which was a division of Sonic Team for the USA. Though they still exist to today as Sonic Team USA, they do not have a game development team anymore. This makes this game the last game to be developed in America by Sonic Team. This game was written and developed by Takashi Iizuka.
Shadow the Hedgehog is a confusing game that contains many paths for Shadow to go through. Each route has two different endings, but neither of those endings are canon. Most stages have three ways to complete them. Those three ways are Hero, Neutral, and Dark. There are also companions on each stage that allows for two players to play. The companions Shadow can get, whether a second player plays or not, are Sonic, Tails, Knuckles, Rouge, Vector, Charmy, Espio, (Memory/Video) Maria, Omega, Amy, Doom's Eye (Black Doom's Eye), and Eggman. Cream and Cheese also appear in this game, but they are not companions. Other characters that appear include Black Doom who is the dark lord of the Black Arms species, Black Arm aliens, Gerald in memory or video, the president of the United Federation, G.U.N., and G.U.N.'s commander. 
There are different combinations one can do when completing stages. For example, you can complete Stage 1 as Hero, Stage 2 as Neutral, and Stage 3 as Hero again. Even though the journey is mixed, the endings for each route you end up clearing for the most will always end up being the same for said route from the choice of two endings for that route. For each route, there are two endings: a good ending and a bad or different ending. How you clear the last stage before that ending will determine which ending you get. Certain cutscenes are consistent and will appear in every route. However, there are certain cutscenes that only appear in certain routes or in the way you cleared the stage.
 There are hints of what path Shadow may have gone through in the Last Story when he thinks to himself lines that people have said to him and what he thought himself on his journey, but not everything is clear. 
====Summary====
thumb|249x249px|A playthrough of Shadow the Hedgehog (2005) by FCPlaythroughs
(Note: The following dialogue scene moments are from the English dialogue. The original Japanese dialogue scenes at times, contain different wording.)
Shadow still has memory loss and he is in thought and wondering who he is. All he can remember is his name, Maria's name and the scene of when Maria was killed, and the past events of Sonic Heroes. While wondering who he is, a large red storm cloud drops aliens, who are the Black Arms, into the city. Shadow says that he has no time for the humans and then hears someone call his name. An alien projects Black Doom, the dark lord leader of the Black Arms, in front of him. Black Doom tells Shadow that the day of reckoning is near and demands Shadow to bring him the seven Chaos Emeralds as promised. Shadow tries to ask Black Doom how he knew his name, who he was, and what was he talking about, but Black Doom just disappears. Shadow thinks that since Black Doom seems to know who he is, that he has to trust him. Shadow comes to the conclusion that he has to get the Chaos Emeralds because he believes they hold the secret to his past. He then skates off into the city nearby.
Shadow first meets Sonic along the way as he tries to assess the situation. It's here, in the Westopolis stage, where you can begin to branch off to different paths. Throughout the game, Shadow isn't quite himself because he has amnesia and it's through this game that he is traversing a journey of self-discovery to find out who he is.
As the aliens attack, the United Federation with G.U.N. try to defend their cities as other places in the world defend theirs. The commander of G.U.N. has a personal vendetta against Shadow, who he lumps with the Black Arm aliens despite having a soldier protest that Shadow is an ally, and orders that the army attacks Shadow on site as well. The reason why he has a grudge against Shadow is because he believes that it was Shadow's fault for being created that the people on the ARK, including Maria, had to die. Throughout the game, Black Doom tries to manipulate Shadow to do his bidding, insisting that the humans are insignificant and have made Shadow suffer, so in turn, Shadow should bring retribution to them. Eggman, throughout the game, lies to Shadow, tries to trick Shadow about his past, tries to get Shadow to help him, and opposes Shadow should he get in the way. His goal was to stop the chaos so that the world wouldn't get destroyed before he can conquer it. Sonic and his friends try to help guide Shadow against opposing enemy forces to save the world or ask for Shadow's help in certain tasks.
Hero Route
(The following is if you clear all stages consecutively on Hero.)
*This route has Shadow fight against all evil, which is mainly the Black Arms. The player must try not to hurt as many G.U.N. soldiers as possible.
* The good comrades you run into are Sonic, Tails, Rouge, and (Memory) Maria
* Sonic is with Shadow the most in this route. He's the one who informs Shadow of the Black Comet in this route.
*Shadow gets a flashback of his time in the ARK where Maria asks him for help to save the researchers from an experiment gone wrong. The memory ends with Maria telling him that everyone is counting on him before she dies and Shadow is launched to Earth.
*On the complete heroic path ending, both Sonic and Shadow fight Black Doom together. What fuels Shadow is his promise to Maria to protect the Earth she loved so much. After Black Doom is defeated, Black Doom says that the Black Arms will rise again. Shadow says at the end, 
* If you decide to turn on the last minute and follow Black Doom on the last stage, you reach the other hero route ending. In this ending, Sonic asks why was Shadow siding with the aliens. Shadow replies that he isn't and is only siding with whoever goes against Sonic for the time being. The boss fight then turns into Shadow fighting against Sonic and Diablon, a G.U.N. robot that is piloted by the G.U.N. commander. After defeating them, Sonic comments that he didn't think Shadow had it in him. This is what Shadow says in this ending: 
*The song, "All Hail Shadow," plays as credits for this route.
Semi-Hero
*This route requires Shadow to sometimes do heroic acts, but also neutral acts such as not following anyone's direction or only going after the Emerald.
*You can run into the Chaotix on this path. They are trying to hack into Eggman's computer for confidential purposes.
*Eggman tries to lie to Shadow, saying that Shadow has no past.
*Shadow remembers some of the time when he and Sonic fought the Biolizard to protect the ARK and when he fell to Earth.
*The G.U.N. commander confronts Shadow, telling him that it's Shadow's fault that Maria and the people of the ARK died. The commander considered Maria as family and when he was a child, he had witnessed Black Doom and Gerald talking besides Shadow in a capsule. He assumed that they were going to release an evil creature. Shadow asks for confirmation and is surprised at his origins. The commander says that Shadow can't fool him and shoots his gun. Shadow dodges by going behind the commander and says that if what the commander said was true, then he will accept his fate. The commander asks if Shadow really doesn't remember anything. Shadow says that he needs time to find out the real truth. The commander falls down to his knees in defeat.
*Shadow asks Black Doom if what the humans say was true, that Shadow was evil. Black Doom confirms it and Shadow looks down extremely sad. Vector asks if Shadow is okay. Shadow then says that if that's true, then he needs to be responsible for his crimes and avenge those who died on the ARK. In response, Black Doom says that the humans have brainwashed Shadow and therefore, he needs to end him.
* The last stage has Shadow traveling with Vector, who asks for help to reach the computer room before the place collapses. If you follow his direction, Black Doom will be waiting in the computer room.
* In the first ending, after Shadow defeats Black Doom who says that the Black Arms will rise again, Shadow becomes depressed and says, Vector tries to comfort Shadow, telling him that things may not be what they seem, but Shadow is too sad to listen as he walks away.
*In the second ending, if you chose to go after the Emerald instead, Eggman intercepts Shadow and tells him that he's a great invention of his grandfather. However, Eggman says that it's now Eggman's time and demands Shadow to hand over the Chaos Emeralds. Shadow refuses, saying that he himself needs to uncover the truth and avenge the victims of the ARK. After defeating Eggman, Shadow tells him to be gone and will not allow him to defile the ARK with his presence. Eggman calls Shadow ungrateful, asking if Shadow forgot that it was his grandfather who created Shadow. Shadow says, Shadow reiterates that Eggman leave and never return, not wanting to allow anyone to violate the sacred ARK.
*The song, "Chosen One," plays as credits for this route.
Neutral Route
* This route requires Shadow to mainly not follow anyone's instructions. This usually means going after the Emerald only.
*Black Doom gets angry that Shadow isn't following his directions so he teleports him to Glyphic Canyon where Knuckles is.
*Shadow teleports to Prison Island and there, he remembers that he was captured by humans and held in this place. You can meet Charmy here.
*Eggman gets angry that the Black Arms and G.U.N. are destroying everything in their fight, ruining his motive to conquer the world. He takes it upon himself to intervene with his robot army.
*Shadow flies with Black Doom on an old Black Arms fortress. Black Doom brags about its capabilities before they notice Eggman and his fleet. Black Doom tells Shadow not to fail him and to bring down the human opposition (Eggman).
*Shadow wonders if he looked down at the blue sky from above before.
* Shadow goes after Eggman, believing that he can tell him about his past.
* Shadow teleports to Iron Jungle and is met with an army of Shadow androids created by Eggman. This makes Shadow wonder if he himself is an android.
*You can meet Omega at Iron Jungle and he asks Shadow if he wants to help chase down Eggman with him.
*When Shadow and Omega confront Eggman, Omega is ready to obliterate Eggman. Shadow stops him in order to ask Eggman in desperation if Shadow himself is one of those androids. Eggman lies to Shadow saying that he is one of those androids. Shadow is shocked. Eggman then says that he made both Shadow and Omega and since they are disobeying him, he has to get rid of him. Shadow falls to one knee in shock and sadness while Omega gets ready to defeat Eggman.
*After defeating Eggman, Shadow starts to go crazy and laughs. Memories of when Eggman found him and encapsulated him, the many Shadow androids back in Sonic Heroes, when he saved the world with Sonic, and when he fell to Earth flash in his mind. He takes this as the real Shadow's memories and believes himself to be a copy of the real one. He then decides to end and send Eggman back to where Eggman had created him from.
*When Shadow and Omega confront Eggman, Shadow says, "Yes doctor, you will regret ever having created me...you're going straight to hell!"
*In the first ending, after defeating Eggman, Eggman asks to Shadow that he created him and this is how he repays him? Shadow replies, Omega gets ready to obliterate Eggman. Eggman is shocked. Shadow then says, "Goodbye, doctor!!" and karate chops Eggman to kill him. The screen turns black and Eggman yells out, "Nooooooo..."
*If you listen to Eggman instead on the last stage, Lava Shelter, you get the second ending. Shadow confronts Eggman and Eggman praises Shadow for doing well and commands him to give the Emeralds. Shadow responds saying that he only collected them to defeat Eggman. Eggman then says that he has to teach Shadow a lesson for disobeying him. As he's saying this, Eggman is treating Shadow like one of his androids and is continuing to lie/trick Shadow that he is one of his androids. After defeating Eggman, the ending is similar to the other neutral ending, except this time, Omega is not present and Shadow says, 
*The song, "Waking Up," plays as credits for this route.
Semi-Dark Route
*This route requires Shadow to listen to Black Doom sometimes as well as not listening to anyone within the stages.
*After the G.U.N. soldiers have been ordered to take down Shadow dead or alive, on the dark routes, it shows these soldiers pointing guns at Shadow and staring him down. Shadow tells them to get out of the way and the soldiers threaten to shoot him. Shadow calls them stupid humans and kicks them down. Black Doom praises Shadow for this. Shadow asks Black Doom who was he. Black Doom comments that Shadow really doesn't remember anything and says that he'll tell Shadow in time. He then commands Shadow to hack the United Federation mainframe, to which Shadow agrees to.
*Rouge appears in the Digital Circuit stage to find the Emerald as a chance to do a Hero clear. Following Black Doom produces a Dark clear.
*After deleting things in the mainframe, Shadow teleports back into the real world at Eggman's computer. He notices Eggman flying outside and thinks that he can ask him about the Black Arms.
*Amy appears on this route in Cryptic Castle. She asks Shadow if he can help her find Cream and Cheese, who also appear in this route.
*Shadow confronts Eggman for he needs Eggman's Chaos Emerald. Eggman refuses and says that if Shadow will get in his way, he'll destroy him like he will do to the Black Arms.
*Black Doom tries to manipulate Shadow when he seems troubled. He pretends to care and help. He shows Shadow an illusion of Shadow and Maria running away from G.U.N. soldiers in the ARK to remind and tell Shadow not to forget what the humans have done to him fifty years ago.
*Shadow is pulled into a memory, which you play as a stage, when the G.U.N. soldiers were attacking the ARK. Maria appears as a companion and she asks Shadow to save the researchers. Black Doom takes her place during the boss and tells Shadow that the humans are horrible and greedy. Shadow gets angry and calls humans heartless.
*The president is sad that he couldn't protect the country, but he has learned to never give up from Sonic and Shadow. They evacuate him from the White House.
*As the president escapes, Black Doom calls the humans pathetic and commands Shadow to make the humans understand their situation.
*On the Air Fleet stage, you can meet Tails who asks Shadow to help the president escape.
*Once Shadow gets five Emeralds, he remembers that Black Doom asked him to give him the Chaos Emeralds. Shadow believes that the truth of who he is will be revealed soon. Black Doom tells Shadow that they have loose rats back at the Black Comet and orders Shadow to come and exterminate them.
*On the semi-dark path for the stage, Black Comet, Knuckles appears and tells Shadow to defeat the aliens with him.
*On the first semi-dark ending, Shadow runs into Eggman as a boss who says to Shadow that Shadow was released to find the Chaos Emeralds. He demands Shadow to give him the Emeralds. Shadow refuses, saying that he needs the Emeralds to know his past. After Shadow defeats Eggman, Eggman says, "How dare you defy...ME!" Shadow says, Shadow ends Eggman the same as the neutral endings.
* On the other ending, if you listen to Black Doom instead of helping Knuckles, the boss is Sonic and Diablon. Sonic tells Shadow that he can't let Shadow go like this. The commander adds in that it's Shadow's fault that the ARK got destroyed and for the deaths that happened on there. Shadow laughs and says, “I know what I have to do. I was born to bring order to the humans. These humans…they don’t value life…they’re going to pay…pay with their lives for what they’ve done!” Shadow tells Sonic that if he tries to stop him, he'll destroy him too. After defeating them, Sonic asks why did Shadow side with the aliens. Shadow pauses before replying, Shadow laughs menacingly.
*The song, "Almost Dead," plays as credits for this route.
Dark Route
*This route requires Shadow to do Black Doom's bidding.
*This route is similar to the semi-dark route, except this time, Shadow clears all stages on Dark.
*Rouge, Amy, and Knuckles appear on this route.
*After defeating Eggman at Cryptic Castle, the story is more different than the semi-dark route.
*The president receives an emergency call telling him that the army was able to push back some of the Black Arms, but reinforcements were heading towards Central City. This shocks the president.
* In Central City, Shadow is with Black Doom and an army of Black Arms aliens. Black Doom decides to share a little bit of Shadow's past. He tells Shadow that Shadow holds contempt and hatred for the humans because they tried to destroy Shadow out of fear of what he can do. Shadow gets brainwashed by this and is coming to believe it. Black Doom tells Shadow to unleash his anger and power on the humans. Black Doom tells Shadow that they have set a bomb in the city and all Shadow had to do was activate it and the city will be destroyed. Knuckles is here in this stage and asks Shadow to help stop the bomb for a Hero clear.
*Black Doom teleports Shadow into space above the world. He comments how Shadow has finally come to realize how abominable these humans are and explains that it’s time for the prosperity ritual. He says that in the ARK, there is a powerful weapon, the Eclipse Cannon. Black Doom tells Shadow that it needs Chaos Emeralds to work or the ritual would be for nothing. Shadow wonders about the prosperity ritual, but Black Doom simply just tells Shadow to go. Black Doom comments that the Cannon was made to protect mankind, but now it will be used to destroy it.
*After Shadow destroys the ARK's defense system, Shadow has to fight the Blue Falcon, a G.U.N. robot that is defending the Eclipse Cannon. He defeats it.
*Black Doom telepaths a message to the world that they are the Black Arms who are going to rule the planet and that any resistance will result in death. As he says this, it shows the city in ruins and the GUN headquarters. Black Doom continues to talk saying that the humans are so pathetic. As he hears Black Doom say this telepathically, the commander curses Black Doom. The next scene then shows the president. Black Doom continues that as of today, the planet is his. The president calls him crazy and begins to say, “We will not…” but Black Doom interjects that they will exterminate all world leaders who resist. The president is shocked. The scene shifts to the ARK. Black Doom says that annihilation for this planet is near and that it’s time to embrace the dawn of their demise and despair. The Eclipse Cannon fires and destroys some of GUN’s ships and then the White House. The city is obliterated as Black Doom laughs evilly. The president had escaped beforehand. The commander asks the president if he’s all right. The president waves away his concern and instead, asks about the people in Central City. The commander says not to worry because the people were evacuated. The president is relieved and tells him, "Very good." A beeping sound happens and a soldier comes in. The commander wonders, what now. The soldier explains that many aliens have penetrated their outer perimeter. He adds that Shadow has been seen siding with them. The president can’t believe it. The commander comments that Shadow has finally decided to show himself and orders for troops to be mobilized as well as the machine, Diablon. The soldier protests, saying that the machine isn’t ready yet. The commander says that he doesn’t care and that they have no other option. They must protect the president and the Emeralds at all costs. The soldier obeys. The commander says that it has been 50 years and that finally, justice will be served. He cocks a gun. Shadow is outside and hears Gerald’s voice saying that he’s counting on him. Shadow replies that he knows towards Gerald. He says that he was the ultimate life form born to ensure peace and justice upon mankind. Now he knows what he has to do.
*In the first ending, if Shadow decides to disobey Black Doom and clear the G.U.N. Fortress on Hero, Black Doom tries to tell Shadow that it's too late to show mercy to the humans. Black Doom becomes the boss and he is disappointed that Shadow disobeyed him. Shadow reminds him that he doesn’t listen to anyone. Black Doom asks what does vermin like him think he can do on his own. Black Doom says those who commit mutiny against him will see no mercy and will not defy him again. After getting defeated, Black Doom says that the Black Arms will rise again. Shadow says, Shadow laughs evilly.
*In the second ending, if Shadow listens to Black Doom, Sonic and Diablon become the boss. The scene is similar to the second ending of the semi-dark route, except this time, Shadow says first for them to get out of his way. After Shadow defeats them, Sonic asks, “Shadow… What are you going to do with them?” (The Chaos Emeralds) Shadow pauses to think and then says, Shadow laughs evilly.
* The song, "Almost Dead," plays as credits for this route as well.
At the true very end of the game, Shadow, Sonic, Tails, Knuckles, Rouge, Amy, and Eggman confront Black Doom. Black Doom demands Shadow, who thought he could finally learn about his past with the Emeralds, to hand over the Chaos Emeralds. Sonic rushes in and tells Shadow to give the Emeralds to him. Eggman tells Shadow not to give it to Black Doom and Rouge tells Shadow that the Black Arms intend to destroy the planet, causing Shadow to be shocked. Black Doom calls them fools and lies that they are trying to save the humans from their own demise. He further explains that the humans' greed, thirst for power, and affinity for betrayal has them on the path of self-destruction and that their actions will lead them to extinction for their species. Black Doom then says that the humans would be a great energy source. Everyone is shocked at this statement. Black Doom says that it's time for the ritual and steals the Chaos Emeralds from Shadow. He uses it to teleport the Black Comet into the city. The Comet then attaches itself to the ground. Black Doom explains that this was why he needed Gerald's help and that he made a deal that if he helped Gerald make Shadow, Gerald would give him the Chaos Emeralds. Shadow falls to the floor on one knee, shocked, while Eggman is in disbelief. Sonic and Knuckles try to lift the mood, but then everyone became paralyzed from a gas that was released due to Black Doom. Black Doom sends his children to eat Shadow and company who cry out in help and displeasure. Shadow closes his eyes and remembers some of the things people said to him on his journey and things he thought himself. Those lines (in English) are:
*"I will avenge those whose blood has spilled!" (The G.U.N. commander)
*"I'm the one who gave you life, Shadow." (Eggman)
*"Did I...die?" (Shadow)
* "Please help me, Shadow." (Maria)
After Maria's line, Shadow gets up, stomps on an alien that was heading towards him, and says, Black Doom is disappointed, saying that it's ironic that he gave Shadow life and now, he's going to take it away. He goes away and Shadow chases after him. Sonic says that Shadow is their only hope now. Back on the ARK, the Chaotix are trying to salvage data. While Shadow is confronting Black Doom, Black Doom tries to mind control Shadow through their shared DNA. The Chaotix then trigger a video left behind by Gerald as this is happening. In the video, Gerald explains to Shadow, his son, that if he is seeing this, then the worst has happened. He explains that he had made a terrible mistake making contact with the Comet and that the only way to destroy it is with the Eclipse Cannon. He also says that Shadow is the only one who can save mankind. Maria also appears in the video and tells Gerald not to worry because she and Shadow will both protect the Earth. Shadow breaks through Black Doom's mind control and says that he's there to keep a promise. Shadow tries to hit Black Doom, but Black Doom teleports away while leaving the Chaos Emeralds behind. Shadow uses the Emeralds to turn into Super Shadow and fights Black Doom's true form. Once Black Doom is defeated, Shadow teleports the Black Comet in front of the Eclipse Cannon and it gets obliterated by the Cannon. Everyone is happy, even the president with G.U.N. who says that despite the way they treated Gerald, he ended up saving them all.
At the very end, Shadow is in the ARK, holding a photo of Maria and Gerald. He says, "Goodbye...Shadow the Hedgehog," and tosses the photo away, signifying that he has put his past behind him and has become anew.
The credits song that plays at the very end is "Never Turn Back."
====Sonadow Moments====
(Note: The following dialogue scene moments are from the English dialogue. The original Japanese dialogue scenes at times, contain different wording. Also, this Shadow that is portrayed in this game has amnesia and is often manipulated by others. )
At the beginning of the opening cinematic cutscene, Shadow loads a gun and appears in front of the moon. He is also seen in front of the moon later in the cutscene as he teleports somewhere else.
*The moon is considered to be Sonic, so this scene can be seen as Shadow going in front of and protecting Sonic (the moon). (To learn more, see Sonic and Shadow - The Moon and The World)
In the opening cutscene, when the lyrics of the song, I Am All Of Me, plays “Here we go buddy, Here we go buddy, Here we go, Here we go buddy, Here we go,” Sonic appears.
Also in the opening cutscene, Sonic is shown falling in battle from exhaustion. When Shadow witnesses this, he goes after for whoever Sonic was facing.
In the first stage, Westopolis, Shadow meets Sonic. When Shadow approaches, he turns to Shadow with a thumbs up and says, “Hey, Shadow! Long time no see! Looks like these black creatures really mean business!” Sonic then follows Shadow, telling him, “Let’s you and me show them a thing or two!” Sonic guides and helps Shadow throughout this stage if the player decides to aim for a Hero clear. If the player doesn't aim for a Hero clear, and instead, listens to Black Doom or go towards the Emerald path in the stage, Sonic will leave Shadow. Some of the lines that are said by Sonic during this stage are:
*“Hey, Shadow! That’s one of the Chaos Emeralds!” (When approaching the Chaos Emerald)
* “With that Chaos Emerald, you can unlock unlimited power!” (When Shadow collects the Chaos Emerald)
*"They all seem to have black and red bodies. When you spot them, smash'em!" (When talking about the Black Arms)
*“Laser strikes causes explosions, so stay clear of them, too!” (When picking up a laser weapon)
*“Let’s run along that fallen crane!”
* “They’ve grafted these red fruits all over the place. Let’s smash them all up!"
* “Watch out for the lasers coming from above!"
* “I don’t know who or what these black creatures are, but we can’t let them get away with this!”
*thumb|251x251px|A playthrough of Westopolis (Hero) by AzureBlade49“Just a few more! Give it your best shot!"
* “It looks like most of the citizens have been evacuated. I feel so sorry for them…"
* “Just what are these black creatures?”
*“Those monsters are out of control!”
* “Looks like our guests decided to pay us another visit! Let’s show them a good time!”
*“Use this to go back.” (When passing or near a teleporter)
*“That’s all of ‘em!” (When you clear the stage on Hero)
A second player can join in and play as Sonic with Shadow in the stages he is present.
At the clear screen and if Sonic is present, Sonic can be seen in the back giving a thumbs up. If you get the Chaos Emerald, it will descend into Shadow’s hand and he grabs it and poses.
In various stages, there are tip bubbles around. Whenever you touch them, the character you are with tells you a tip. Here are some of what Sonic says to Shadow. (There are still more to be found):
*“To swap your weapon for another weapon that’s on the ground, just press the X button! Personally, I wouldn’t be caught dead using those things!”
*“Defeating the black creatures will make your blue gauge fill up and let you use your super powers!”
*"Grab that to charge your Dark Gauge up to full!"
*"If either the blue or red gauge is filled up, press the Y button to use one of your special moves! The power of justice lets you use the teleport using ‘Chaos Control.’ If you’re fueled by evil, though, you’ll be able to unleash the destruction of ‘Chaos Blast!’"
When next to a GUN jeep and Sonic is present, Sonic tells Shadow to “Press the X button to hop on and go for a ride!”
In stages, when Shadow defeat aliens and Sonic is with him, he will praise Shadow with the following lines:
*"Nice job, Shadow!"
*"Hey, not bad!"
*“Yeah! Smash em’ up!”
*“There’s still more to go! Don’t get cocky!”
In stages when Shadow hurts G.U.N. or their robots and Sonic is present, Sonic will say to Shadow:
*“Hate to tick off GUN, but looks like using Homing Attacks on those robots is the only way past!”
*“Shadow, what are you doing?!"
*“Hey, he’s on our side!”
*“Stop!”
In stages where Sonic is present and an alien surprise attacks or appears at a certain part, Sonic will say to Shadow, “Well, look what the cat dragged in! All right, Shadow, you know what to do!”
When Sonic is present with Shadow in stages and the mission isn't complete yet, for example, if all the aliens haven't been eliminated yet, Sonic will say, "There’s just one more somewhere!"
On the Hero route, after Shadow gets two Chaos Emeralds, Sonic runs up to him and says, “Now that was SWEET, Shadow!” Shadow scoffs and replies, “Yeah. Well I’m not here to save you!” Sonic runs to face him in the front and says, “Thought you might say something like that! How about a little friendly competition?” Shadow turns away with arms crossed and says, “Don’t waste my time.” Doom’s Eye appears in front of them and tells Shadow that they found the third Chaos Emerald in the city, that their mission there is done, and to get going. Doom’s Eye flies away. Sonic then comments, “Guess that means…welcome to the next level, let’s go!” He runs off. Shadow then calls out to him, “Get back here!” and chases after him.
On the Lethal Highway stage, Sonic is waiting for Shadow up ahead. When Shadow comes, Sonic asks him, “Shadow, where have you been, slowpoke?” He then comments, “Looks like the black creatures have turned tail and ran! Let’s follow their vehicle and finish what we started!” Here are some of the other lines Sonic says to Shadow on this stage:thumb|261x261px|A playthrough of Lethal Highway (Hero) by AzureBlade49
*“The tank’s barrier seems to be deflecting bullets.”
*“Watch out, Shadow! Sections of the roadway are being destroyed by those black creature’s bombs!”
*“Why is GUN after us, now?! Shadow, what did you do?!" (They are after them because the G.U.N. commander has a grudge against Shadow, believing that it is Shadow's fault that Maria and the others on the ARK died.)
*“That’s a Beetle. A GUN sentry droid!”
*“GUN forces are giving their all! We’ve gotta help them!”
*“Hey, watch out! Those red, thorny fruits are poisonous!”
*“Man, I thought we lost them, but I think we can still catch up! Let’s go!”
*“Shadow, try grabbing onto that horizontal bar.”
* “That barrier isn’t invincible! If you do enough damage to it, you should be able to get through!”
*“Yes, we did it!” (When the alien ship is defeated)
On the Hero route, after defeating the alien spaceship, Sonic and Shadow run up to Doom’s eye. Shadow demands that he hands over the Emerald. Doom’s Eye then says, “So, you think you have a chance against ME… do you?” Shadow then tells him that he doesn’t take orders, especially from him, but he isn’t there to fight him either. He then says that he’s collecting Emeralds to find his own answers and tells Black Doom to back off. Black Doom is displeased and questions him that he still doesn’t know his place. He summons an alien called Black Bull. He tells Shadow to behold the wrath of the Black Arms. Sonic cheers, putting his fists up, “Woohoo! Now we’re talking! Bring it on!!” Shadow looks at him as he says this and then looks back towards the enemy.
On the Hero route, during the fight against Black Bull, as Sonic helps Shadow, some of the lines he can say are:
* “Hey, check you out, big guy! Let’s have some fun!”
*“That monster can spit out those little bird creatures. Use its little pests against it!”
*“That things blubbery body seems immune to most attacks! You need to find out its weak spot!”
*“You can use your homing attack to attack repeatedly in the air!”
* “Yeah! You’ll kick this thing’s butt in no time flat!”
*"It’s not dead yet! Keep going!”
*“Way to go, Shadow!”
*“Yes! End of the line for you!” (When the boss is defeated)
In the cutscene where the president is first introduced, he is briefed about the current conditions of the war against the aliens. He says that the United Federation will never surrender to terrorists. He then glances at the photo of Sonic and Shadow in front of the White House on his desk and comments, “This planet was once saved from tyranny and annihilation by you two heroes. Now mankind must protect this peace… at all costs.” He then says that we must stand united to defend their world against the invaders as he stares at the sunset.
* On the back of the Sonic and Shadow photo is stamped "SEGA."
On the Hero and Semi-hero routes, Shadow teleports to Iron Jungle, an area where Eggman’s technology is. He looks at his surroundings and a spaceship docks near him. Shadow turns to look and sees Sonic. Sonic says, “What’s up, Shadow?” Shadow shakes his head and says, “Not you again.” Sonic replies with, “Nice to see you too!” Sonic then talks about the problem. “Looks like those black creatures are headed out to space. We’re on our way to the ARK, so I guess that means we’re going too!” Shadow looks away and down repeating in thought, “ARK…” Sonic tells him, “Come on, let’s roll! Next stop, the ARK!” Shadow nods and comes aboard the spaceship too. The spaceship takes off.
On the Hero route, Sonic and Shadow are walking in the ARK. Shadow mentions Maria’s name. Sonic then directs Shadow’s attention to above. Shadow says, “Huh?” as he looks up. Shadow asks what it is. Sonic explains that it’s the Black Comet that passes by once every 50 years by Earth. Sonic then says, “Hehe… oh? Do you think those black creatures are somehow connected with that comet?” Shadow repeats the name, thinking until a headache attacks him. He grunts in pain as he kneels down on one knee. Sonic in concern asks, “Shadow, what’s wrong?” Shadow slowly gets up and says, “I think you’re right… I feel it… they’re up there. That’s where the answers are… I’ve got to get to that comet!” He puts his hand in a fist in determination and the two head off.
On the Final Haunt stage, if going for a Hero clear, Sonic goes with Shadow and comments, “Well, Shadow, it looks like we’ve reached the climax of our little game. Time to make the big boss man responsible for this invasion, step up and play!” Sonic guides and helps Shadow again. Things he says are:
* “There are aliens up on the bridge. They’re trying to get us!”
*“It looks like this cage has been locked by those black creatures!”
*“We need to find a way to the top of that bridge!”
* “Shadow! Try going up!”
*“Yahoo!” (When going off a speed ramp or speed ring)
*“Shadow, look! The aliens have decided to send in the best of the best!”
*“That weird alien weapon can suck up Rings, items, and even small enemies! It looks like it works just by holding the B button. Give it a try, Shadow!”
*“I can’t wait to see what the big boss himself looks like! Let’s go!”
* “You can probably Jump Dash between these walls and perform the Triangle Jump!”
*“It’s the black creatures! Time to have a little fun!”
*“Yo, try going down there!”thumb|269x269px|A playthrough of Final Haunt (Hero) and Black Doom Boss with cutscenes by AzureBlade49
*“You know what they say… the bigger they are, the harder they fall!”
*“Watch your step! Take a look below.”
*“It’s dangerous up ahead. Watch your back!”
* “Don’t touch that switch! That’ll seal off the path that we need to follow!”
*“Try sucking up those mines with the vacuum gun!”
* “I think we might be able to pull something outta this different-colored wall.”
*“Is there any way we can shut down the lasers that are defending the exit?”
*“Don’t waste time shooting at the black creatures with shields! Take them out using Homing Attacks!”
* “This wall is a different color than the others. That’s kind of weird…”
*“Zoom along that red alien slime!”
*“Shadow, get on!”
*“That might just be a decoy to trap us, but it’s our only clue we have right now. Guess we’ll just have to follow him!”
*“Great, like we needed another problem! Can you still fight, Shadow?”
*“What is it, Shadow? Is there a shield in the way? It must be linked to a switch somewhere back along the way we came.”
On the Hero route on a final Hero clear, Shadow and Sonic walk up to Black Doom. Black Doom tells Shadow that he’s impressed that he has made it this far. Shadow replies with emphasis via his hands, “Black Doom! Your rule ends here and it ends now!” Sonic walks to the side of Shadow and says, “So you’re behind all this… Like it or not… the game’s OVER!” Black Doom laughs and calls them fools saying that the Black Arms are more than superior, they are perfect. He asks if they think that they have any real chance of defeating them and laughs. Shadow says that it’s Black Doom who should be scared as he points at him. He then says, “I made a promise to Maria to save the planet she loved so much… and I WILL!” Black Doom tells him to get ready to die as he shows him the ultimate power in the universe.
On the Hero route on a final Hero clear, during the boss fight against Black Doom, Sonic says, “This is it! Let’s end this once and for all!” While fighting, Sonic guides Shadow through the fight. These are some of the lines he can say:
*“Attacks won’t work on his body! Aim for a weak point!”
*"If you can get up high enough, you can hit with a Homing Attack!”
* "When he throws meteors, make sure to get outta the way!”
* "Using our speed, avoiding that disk attack by dodging it to the side is a snap!”
*"It looks like there’s a pattern to his teleportation! Go and show him who’s boss!”
On the Heroic clear ending on the Hero route, after they defeat Black Doom, Black Doom falls upon the floor and Shadow receives the last Chaos Emerald. Sonic watches with his hands bent on his hips. Shadow then says, “Finally… I’ve got ALL the Chaos Emeralds!” Black Doom tells Shadow that it isn’t over yet and that the Black Arms will wise again. Sonic walks up and says, “Let’s do this!” Shadow then says, “I’m Shadow the Hedgehog, and I made a promise that I intend to keep! With the power of these Emeralds, Black Doom and his army are finished! This is WHO I AM.”
On the Hero route with a final Dark clear, Sonic confronts Shadow with Diablon and asks, “Shadow! Why are you siding with those black creatures?” Shadow replies, "Siding with them… you're joking, right? I'm just siding with whoever goes up against you. This time you’re going down, Sonic!” Sonic laughs and replies, “If that’s how it’s going to be, Shadow. Then bring it on!” Sonic makes punching movements and gets ready to stop Shadow from doing bad. Shadow then says, “Just say when!”
When the above fight begins, Sonic asks, “All right! You ready to do this? Come on!” Shadow then says, “All right, Sonic. Defend yourself!” During the fight, Sonic can or will say these lines. He also says these same lines whenever you fight him in other routes:
* "Ugh, not bad, Shadow! But the fun’s just getting started!” (When Shadow hits Sonic)
*"Heh. You’re pretty good. But now, playtime’s over!"
On the clear screen for beating both Sonic and Diablon on the Hero route (Dark), Shadow says, “It’s do or die, Sonic the Hedgehog!”
On the Hero route with a Dark clear second ending, Sonic is tired and is defeated on the floor. The Chaos Emeralds surround Shadow and after a pause, he says, “Finally… I’ve got ALL the Chaos Emeralds!” Sonic shakes as he looks up at Shadow and says, “Man… I didn’t think you had it in ya.” Shadow then says, “I’m Shadow the Hedgehog… and now, I am the most powerful hedgehog in the world! The power of these Emeralds makes me invincible! I am the ultimate hedgehog… This is WHO I AM.” Shadow laughs in triumph.
The Hero route is the route that Shadow spends the most time with Sonic in the game.
On the Semi-Hero route, as the airship goes to the ARK, Shadow comments to himself, "Space Colony, ARK… This place… so familiar but why? This is… where I… " He starts to remember when he fought together with Sonic against the Bio Lizard, Maria’s name, and that he fell to Earth and possibly died. Sonic comes from behind and says, “Ah yeah, bring it on!” Outside, many Black Arms aliens surround the ARK. Sonic then says as he looks at Shadow, “Looks like the party’s getting started! Time to rock and roll!” He quickly turns to Shadow and brings himself closer to ask, “You up for this, Shadow?” before dashing off. Shadow shows determination before following after.
When the stage, Space Gadget, starts, Sonic asks Shadow, “Don’t you remember? We once raced each other here. This is just like old times! A race for the Emerald!” (Sonic is referring the time he raced Shadow on the ARK in Sonic Adventure 2) If you play through the stage with the intention of getting a Hero clear, Sonic also says the following to Shadow throughout the stage:
*“It’s been a long time since the two of us ran along here together! Now, time to kick things up a notch!”
*“Sorry, but that Emerald is mine! See ya!”
*“Hey! What’s the matter, Shadow? Can’t keep up?”
After Shadow clears the Space Gadget stage on Hero, Shadow remembers Sonic and says during the clear screen, “Sonic… Now I remember, that day, we fought here aboard the ARK.”
As the time runs out to beat Sonic in a race to the Emerald on the Space Gadget stage, Shadow says, “Why? Why do I know this place?”
thumb|243x243px|A playthrough of Space Gadget (Hero) by AzureBlade49
On the Space Gadget stage, if you clear on Normal and let Sonic get the Emerald, he says, “Score one Chaos Emerald for the good guys! Sorry there, Shadow old buddy!”
In a scene on the Normal route, Shadow starts to go crazy and laughs. He starts to have memories of himself when he was found by Eggman, was encapsulated, and the many androids of himself back in Sonic Heroes. He then remembers how he saved the world with Sonic and fell to the Earth. The pieces are coming together for him, however, he attributes the Shadow in his memories to be the real Shadow who had died instead of himself, whom he thinks is a copy. He then decides what he has to do and it is to kill the Doctor. Shadow states, "You're going straight to the place you created me from!"
On the Semi-Dark Route, there is a cutscene where the president is sad that he couldn’t protect the country. The commander comes in and tells the president that they still have a chance even though they may be rendered useless at this moment. He tells the president that he must keep his nation strong and together. The president responds, “Yes, keep the nation united. No matter what happens, we will never surrender to these creatures! This much I learned from them.” He gazes over at the photo of Shadow and Sonic on his desk as he says this.
* It is in this cutscene where you can see the back of the Sonic and Shadow photo. Behind it is "SEGA" stamped behind it.
* The president is inspired by Sonic and Shadow while looking at their photo to be a hero like them.
On the Semi-Dark route, if you clear Black Comet on Dark, you will also face Sonic and Diablon like in the Hero route on a Dark clear. The scene is similar, but Sonic and Shadow say something different. The commander also adds to the conversation. Sonic says, "Shadow! I can’t let you go… not like this!” The commander adds in that it was Shadow’s fault that the ARK got destroyed and for those who died on it. Shadow laughs and responds, “I know what I have to do. I was born to bring order to the humans. These humans… they don’t value life… they’re going to pay… pay with their lives for what they’ve done!” The commander replies with, “YOU!!” Shadow then tells Sonic, “Sonic, if you try to stop me… I’ll destroy you too!” Sonic doesn’t say anything and prepares to fight.
On the Semi-Dark route, when the boss fight against Sonic and Diablon begins, Sonic says, “I never thought I’d have to fight you like this, but I guess I have no choice!”
When you beat Sonic and Diablon on the Semi-Dark Route, Sonic is beat and tired on the floor. Shadow is surrounded by the Chaos Emearlds and says, “Finally…I’ve got ALL the Chaos Emeralds!” Sonic, confused and weak, looks up at him and lifts his head to sadly ask him, “Shadow…Why…Why are you siding with them?” Shadow pauses before replying, “I’m Shadow the Hedgehog, the ultimate life form born to protect and serve the dark lord, Black Doom. With the power of the Chaos Emeralds, this world will become the dark empire. This is WHO I AM.” Shadow laughs menacingly.On the Dark Route, Shadow can also fight Sonic and Diablon. The cutscene where they confront each other is similar, except Shadow says first, "Get out of my way!" Sonic replies, like in the Semi-Dark route, “Shadow! I can’t let you go…not like this!”
When the fight against Sonic and Diablon starts on the Dark route, Sonic says, “Let’s do this, Shadow!”
On the Dark Route on a Dark clear, after defeating Sonic and Diablon, the Chaos Emeralds surround Shadow. Shadow says that he finally got all the Chaos Emeralds. Sonic, all beat and tired, weakly looks up to him and asks, “Shadow… What are you going to do with them?” Shadow pauses to think and then says, “I’m Shadow… the Hedgehog. I was created to bring order and justice to the humans. With the power of these Emeralds, I’m going to destroy this damn planet! This is WHO I AM!” Shadow laughs evilly.
In the Last Story, Shadow finally gets all the Chaos Emeralds. He comments on this and says, "Now, I can uncover the truth about my past. All of it..." Black Doom appears and praises Shadow. He mentions that the ritual can commence as planned and demands that Shadow gives him the Chaos Emeralds. Shadow stares dumbstruck until Sonic and company rush in and shout out Shadow’s name, to which Shadow responds with a "Huh?" Sonic, who is the nearest to Shadow, says, “Shadow, give me the Chaos Emeralds!”
When Black Doom teleports the Black Comet to Earth, it causes a shake where Shadow and company are. Amy asks what was that and what just happened. Sonic says, “Those black creatures just warped the comet down to the surface using Chaos Control!” Rouge is in disbelief and says that that’s impossible. Shadow then realizes and says, “That’s why you needed the Chaos Emeralds.”
After Black Doom explains that he made a deal with Gerald that if he helped him create Shadow, Gerald would give him the Chaos Emeralds, Shadow is surprised and can’t believe it as he falls one knee to the floor. Eggman can’t believe it either that Gerald would betray his own people for research, for Black Doom. Sonic laughs and attempts to try to lighten the mood by saying, “Big deal… We can’t just stand here doing nothing!”
Black Doom releases paralyzing gas, making everyone still. After reflecting on his journey, Shadow is able to break free and declares, “I am Shadow the Hedgehog. I’ve left the past behind me. No one can tell me what to do now! I will destroy you, Black Doom!!” Black Doom says that he gave Shadow life and this is how he repays him. He also comments on the irony that he gave him life, but now, he will take it back. Black Doom laughs and leaves. Shadow rushes off after him. Rouge calls out after him. Sonic says, “You’re our only hope now!”
On the Last Way stage, Shadow chases down Black Doom and Eggman communicates with him. Through this communication, Sonic and the rest talk to him. Sonic says, “Use Chaos Control to make your way inside!”
After Shadow saves the world by teleporting the Black Comet in front of the Eclipse Cannon to get destroyed, Sonic and company cheer and comment. Sonic compliments Shadow with, “Shadow… that was SWEET!”
===Sonic the Hedgehog (2006) ===
==== Overview ====
thumb|252x252px|Example of a playthrough of Sonic the Hedgehog (2006) by FCPlaythroughs
Sonic the Hedgehog (2006) released in the year stated. It introduces three new important characters, Silver the Hedgehog, Princess Elise, and Mephiles/Iblis. There are three main episodes where you can play as the three main characters, Sonic, Shadow, and Silver. Each episode intertwine and shows each main character's story within the grand overall story until they converge at the end with the Last Episode. Other characters that you can play in certain areas and stages are Tails, Knuckles, Omega, Rouge, Blaze, and Amy. Other important characters that appear are Eggman and Princess Elise's father. This is the last Sonic game Yuji Naka was a part of.
* The events that occur in this game never happen due to Princess Elise blowing out the Flame of Solaris. This, in turn, prevented the flame from growing stronger and causing all the events that happen from it. Though these events never happened, the cast seem to have vague memories of it from time to time as if it were a Mandela effect.
==== Summary ====
The story takes place in Soleanna where the Fire Festival is occurring. Princess Elise is about to light the celebratory monument when she receives a vision of the city being engulfed in flames due to a fiery creature. She is reeled back into reality by her attendant and Elise assures her that everything is all right. She carries on with the ceremony, but the festival is soon interrupted by Eggman. Eggman wants the secret Flames of Disaster from Princess Elise. Sonic rushes onto the scene and Elise confuses him for Silver who in the past, helped her as a child. For the moment, Sonic is able to get Elise away from Eggman. However, he gets distracted by Eggman's robots and Elise is kidnapped. Before she is gone completely, she throws her blue Chaos Emerald to Sonic.
Sonic takes it upon himself to save Elise and protect her. As the story progresses, Sonic saves Elise a few times before she is taken by Eggman again. They also get closer together and bond. He is moved when Elise apologizes and patches up his injury, attributing it to be her fault.
Meanwhile in the future, Silver and Blaze are in a fiery world destroyed by Iblis. They continue to fight Iblis, only for Iblis to rise up again and continue his flames. Frustrated by a lack of progress or solution, Silver is approached by Mephiles, the main villain. Mephiles shows himself as a form similar to Shadow, who trapped him in the Scepter of Darkness in the past. Mephiles tricks Silver into believing that it is Sonic's fault that Iblis was released and had destroyed the world. With this knowledge, Mephiles transports Silver and Blaze into the past where Sonic is alive. Blaze thinks of "blue hedgehog," but it seems that she doesn't remember who he is. However, she has a feeling that he may not be what Mephiles claims him to be. Silver tries to kill Sonic two times. However, on the second time, Shadow stops him. After fighting each other, Shadow tells Silver that if wants to know the truth, to follow him into the past. Silver follows Shadow into the Chaos Control portal they had created and they find themselves in the Soleanna Aquatic Base laboratory. In there, Elise's father and a group of researchers were trying to control Iblis, but he refuses to listen. The machine goes out of control and Elise's father shields Elise from the explosion after she walks in. Shadow and Silver go and see what the commotion is about and see the aftermath. Shadow tries to wake Elise's father and they both realize that both Iblis and Mephiles are escaping from the machine. They decide to go after them, but before they leave, Elise's father stops them and tells Shadow to seal Mephiles with the Scepter of Darkness. They catch up to their respective targets and seal them. Silver watches Elise's father seal Iblis within Elise. Before Shadow and Silver go back into the present, Silver leaves his blue Chaos Emerald with Elise. Silver now knows that Sonic isn't the Iblis Trigger as Mephiles labeled him so, and decides to work together with Sonic.
The reason why Shadow appeared in White Acropolis and Soleanna was due to a request from the president. The president requested Shadow to help rescue one of his agents, which is Rouge. Rouge's mission from G.U.N. was to obtain the Scepter of Darkness. Eggman follows Shadow and Rouge to the rendezvous point with G.U.N. in order to take back the scepter. As he intercepts them, the scepter falls onto the ground. Seeing the immediate danger, Eggman retreats as Mephiles is released from the scepter breaking. As Mephiles materializes, he assumes a similar form to Shadow and says that he has to repay Shadow for what he has done to him. At this present time, Shadow has no idea what Mephiles is talking about because he hadn't gone to the past yet. Mephiles then transports Shadow and Rouge into the future in order to trap them there. In the future, they find Eggman's computer with information telling them that they were at least 200 years in the future. This makes them realize that Mephiles can control time. They then hear a noise and when they go to check on what it was, they find Sonic, Tails, and Knuckles who were tricked by Eggman and transported into the future as well. They work together in order to get back into the present. However, although everyone else went back into the present, Shadow remained behind to face Mephiles. Rouge, in the present, notices that she is back into the present without Shadow. She then contacts Omega and tells him to deliver the Chaos Emerald she had to Shadow and assist him in the future. Meanwhile, back in the future, Mephiles offers Shadow to turn over to his side by using humanity betraying Shadow in the future as a reason. Mephiles says that when Iblis was released, the people wanted a scapegoat to blame and that scapegoat became Shadow due to their fear of his power. The humans in the future then imprisoned Shadow out of this fear. Shadow refuses Mephiles' offer and says that he determines his own destiny. He fights Mephiles with the assistance of Omega, who slept for years until this moment with the Chaos Emerald entrusted to him. They chase Mephiles back into the present. Omega is assigned to follow Mephiles while Shadow goes after Eggman to get information as to what is going on. Once face to face with Eggman, Eggman tells Shadow to find out the truth himself on what happened ten years ago by pursuing Mephiles. It is after this where Shadow sees Silver trying to kill Sonic and he goes to stop him. 
When Shadow came back from the past where he sealed Mephiles with the help of Silver, he, Omega, and Rouge then go to pursue Mephiles in the present. Shadow tries to imprison Mephiles into the Scepter of Darkness, but the same method doesn't work. Mephiles asks why Shadow is doing this when humanity will betray him. Shadow answers, “If the world chooses to become my enemy, I will fight like I always have!” He takes off two limiters and with his power, he mows through Mephiles' mass of clones with Omega and Rouge behind him. Once Silver helps Sonic go back into the past to prevent Elise and Eggman from dying due to Eggman's ship crashing, he and Blaze go back into the future to seal Iblis. After defeating Iblis, Silver tries to seal Iblis within himself to no avail. Blaze then takes on that role and tells Silver to seal her away in another dimension. Silver says he can't do it for he wouldn't know what to do without her. Blaze, in response, says that he is naïve, but that's what she likes about him. She also reminds him that they swore to save the world at any cost. She then does the action herself, sealing Iblis within herself and transporting herself to another dimension. She floats up, wishing Silver good luck, and fades away when the clouds disperse, revealing the blue sky. Silver looks down in sadness. 
After Sonic rescues Elise from Eggman's crashing ship, Mephiles sneaks up on them. He distracts them with the purple Chaos Emerald and shoots a beam through Sonic's chest, killing him. Elise's father told her to be a strong queen and to never cry. This is because that was the seal to Iblis. The grief is too strong and Elise couldn't stop herself from crying, therefore releasing Iblis. Mephiles then uses the Chaos Emeralds to reunite as one with Iblis. Everything is swallowed into a pocket dimension and the cast meet each other there. Everyone is shocked and sad to see Sonic lifeless. However, Elise says that his presence is still around and that it may not be too late. Silver mentions that the Chaos Emeralds can call him back and that Elise, someone who was the vessel for Iblis, can do it. The group then goes after the Chaos Emeralds to revive Sonic. Once collected, Elise prays to the Emeralds, wishing to save the world, cleanse her father's sin, and to talk to Sonic once more. She says, "Sonic, come back! To me...To us!" Elise then kisses Sonic's lifeless lips and he awakens as Super Sonic. He thanks Elise after he prevents her from fainting. Sonic then shares his Super power with Shadow and Silver. The two go Super along with him and the three of them face Solaris. 
Once Solaris is defeated, Sonic and Elise are transported into a void, which turns into the the past when the flame of Solaris was still small. In the past, her father said that once the flame has grown stronger, it will give them the power to go through time and fix past mistakes. Elise tells Sonic that if they blow out this flame, the events that had happened would have never happened, including her meeting him. Elise then looks at Sonic and says to him, “I…To tell the truth…” she sheds a tear and continues, “I don’t care what happens to the world!” She says this despite wishing to save the world earlier when reviving Sonic with the Chaos Emeralds. This is also similar to when Amy said she would choose Sonic over the world when she prevented Silver from hurting Sonic further. Sonic is taken aback from this statement and is not sure of what to say. He then decides to tell her to just smile, like how he did earlier in the game. Elise then forces a smile as she looks at Sonic. Sonic then nods and smiles back. Elise then nods herself and sadly puts out the flame. As the flame goes out, everything fades to black. 
The scene then shifts to the festival happening again. Everything is reset as if the game's events hadn't happened. As the festival goes on as it did in the beginning of the game, Sonic rushes through the area. Feeling the wind from Sonic running through the area, Elise feels his presence and comments on how it felt familiar. The game then ends with Sonic staring at the moon as Elise's feather floats up to it. 
The credits songs played for each episode and overall game is as followed: 
* Sonic's Episode - Sweet Dreams (Sonic 2 remix with added lyrics), His World
* Shadow's Episode - All Hail Shadow, His World

==== Sonadow Moments ====
(Note: The following dialogue scene moments are from the English dialogue. The original Japanese dialogue scenes at times, contain different wording.)
When Sonic, Tails, and Knuckles get transported into the future by Eggman, Shadow and Rouge find them. Shadow explains to them that this was the distant future far removed from their own timeline. Tails asks, “The future?” Tails then realizes that Eggman’s machine can control time. Sonic says that Eggman has got some nerve dropping them there. Knuckles kicks a rock and asks how can they get back to their own time. Shadow replies, “You need a space-time rift, but this requires a lot of energy.” Sonic looks at Shadow and says, “I see. You mean using your Chaos Control will…” Shadow interjects and says, “Yes, but that alone is insufficient,” as he points at Sonic. Sonic then says, “Okay Shadow. It looks like we need to work together.” Shadow and Rouge nod in agreement.
In the apocalyptic future, Tails contacts Rouge and tells her that he found something. When Shadow and Rouge meet up with Sonic, Tails and Knuckles, Shadow asks Tails what he had discovered. Tails tells them that he found readings of a Chaos Emerald, but... Rouge continues for him saying that they would have to go through the dangerous volcanic area. Knuckles gets in her face and says that if she didn't like it, she could just stay. Rouge comments that he has got to be kidding. Sonic points at Shadow and says, “Don’t be late.” Shadow nods and walks next to Sonic saying, “Same to you.” After a short pause, Shadow runs off with Sonic following after. The rest follow after as well.
After getting the other Chaos Emerald, Sonic and Shadow face each other. They both take out the Chaos Emeralds, nod to each other, and cross arms with the Emeralds as they shout, “Chaos Control!” A portal to the present is made and Sonic jumps through, followed by Tails and Knuckles. Rouge is seen following after, but Shadow notices something behind and turns to look. He ends up not going with them and stays behind. When Sonic, Tails, and Knuckles arrive back to their own time, Tails asks where did Shadow and Rouge go. Sonic replies, “Those two can take care of themselves.”
When Silver confronts Sonic the second time, he is able to constrict Sonic with his psychic powers. Silver shouts, “It’s time to end this!” Before Silver strikes the final blow, he notices someone coming and leaps back. Shadow jumps in front of Sonic, protecting and saving him from Silver’s hold. Sonic falls to the ground as he tries to get his bearings. Silver asks, “Who? Mephiles! Why are you getting in my way?” Shadow stands up and says, “I’m Shadow. Shadow the Hedgehog.” Shadow looks back at Sonic, who gives him a smile and a thumbs up. Sonic then rushes off, leaving things to Shadow to take care of. Shadow and Silver then get ready to fight.
In the menu select for the Last Story, Sonic is standing in the middle with Shadow and Silver at his sides. The icons of their faces on the right has Shadow after Sonic. After Shadow is Silver.
When Sonic's lifeless body is brought to attention, Shadow looks away for a bit, not being able to fully take his passing. Throughout this scene, Shadow can be seen closing his eyes and lowering his arms, only to cross his arms again and turn further away from the sight when Silver mentioned that that was the reason why Mephiles told him (Silver) to kill Sonic.
Eggman states that defeating Solaris now, here, would do nothing. Silver says that he won’t give up, that there has to be a way. He says if Eggman says that it exists in the past, present, and future, he’ll destroy them all at once. Shadow says in response, “Certainly, it might have been possible, if he was still alive,” as he looks at Silver and then at Sonic. Amy then cries out Sonic's name again, causing Shadow to look away from Sonic once more.
In order to resurrect Sonic, the Chaos Emeralds, which are scattered in the dimension, are needed. Sonic's friends and Silver each go out to collect them. When Shadow collects his designated Chaos Emerald, he states, “Okay, this is it! Sonic…here I come.” Shadow is the last character the player plays in the mission to collect the Emeralds.
After Sonic turns into Super Sonic, he gazes at Silver and Shadow. They form a triangle and nod to each other. Sonic then spreads his Super power to them, turning them Super as well. They head off together to face Solaris.
When fighting Solaris, Sonic says, “It’s all you, Shadow!” when switching to Shadow. One of Shadow’s replies when switched from Sonic is, “Understood.”

===Sonic and the Black Knight===
Sonic goes into a storybook universe for the second time. There he meets counterparts of his friends like Lancelot who resembles Shadow.
===Sonic Colors (DS)===
====Overview====
Sonic Colors DS is a similar game to Sonic Colors Wii Version. In the DS version, there is more story and missions available. Other characters other than Sonic and Tails also make an appearance. The other characters you meet are Cream and Cheese in Tropical Resort, Silver and Blaze on Sweet Mountain, Vector, Charmy and Espio on Planet Wisp, Knuckles and Rouge in Starlight Carnival, Amy Rose and Big in Aquarium Park and Shadow and Omega in Asteroid Coaster.
====Summary====
Sonic and Tails go and visit Eggman's amusement park out of concern for what evil plan Eggman is planning next. Tails tries to convince Sonic that Eggman couldn't be up to anything and that it is a regular, and cool, amusement park. Sonic isn't convinced and goes looking around the park anyways to make sure that things are truly normal. While he is looking around, he runs into Orbot and Cubot trying to capture creatures called Wisps. At first, Cubot asks Sonic and Tails for help in trapping the Wisps, but Orbot then recognizes Sonic and Tails and starts to panic. Orbot then surmises that they should give up on capturing the Wisps for now and go tell Eggman that Sonic and Tails are here. After Orbot and Cubot leave, the Wisps get all excited and start nudging against Sonic, which later results in the White Wisp fusing with Sonic. This powers Sonic up, which then makes Sonic go test run his new powers. After his test run, he meets up with Tails again.
When Sonic gets back to Tails, Sonic first asks Tails if he was impressed after seeing him use the new power the Wisp gave him. Tails first shows concern by asking if Sonic is okay to which Sonic replies saying that he was just surprised and that he felt a rush of power when the Wisp entered his body. Tails is confused by this and wonders how Sonic can tell he had a power boost when he always is super charged. Sonic then replies that this type of power is different. He then decides to go figure out what Eggman is up to with the help of the Wisps.
While admiring the scenery, Sonic and Tails hear Cream scream from Cubot trying to take Cheese away from her due to mistaking the Chao for a Wisp. Cream refuses to give her friend to them, but Orbot insist that they just want to see Cheese and that there's no reason to get fussy. Sonic then comes to the scene and tells Orbot and Cubot to back off. When Cream sees Sonic, she gets overjoyed. Cubot at first says that Sonic looks familiar from somewhere, to which Orbot reminds him that Cream just said who he is. Orbot then comments on how he's surprised that Sonic was able to get here so fast. Sonic replies to this saying to not doubt his speed. Orbot laughs at this which makes Sonic ask him why he's laughing. Orbot then says that Sonic may be fast on his feet, but asks if he can get through this mission. Sonic then completes Orbot's mission saying it was too easy. Orbot then says that Sonic is too fast and Cubot says that he wants to go home. They both end up leaving in fear of Sonic's speed after this. Cream then praises Sonic by saying that he was amazing and then thanks him along with Cheese for helping them. Sonic says that it's no problem. Cream then spots Tails and thanks him too, but instead of responding to Cream, Tails asks Sonic where he's been. As he was saying that he's been looking for him, Sonic cuts him off saying that it was his bad. Tails then asks Cream what she was doing here at the amusement park. She responds saying that she saw a fun ride and ended up there. Tails surmises that what she saw was the elevator to get to the park. Cream confirms this suspicion and says that it was exciting. Sonic comments on this saying that Cream should be more careful around strange looking machines.
It is later revealed that Eggman is actually kidnapping Wisp planets and turning them into amusement park attractions while making its Wisp inhabitants become his power source for his new invention, which is a mind control machine. While Sonic is trying to free the Wisp planets, Eggman continues to drain the power out of Wisp, which turns them into Voids and Frenzies. The factory that drains the Wisps is on Asteroid Coaster, where Sonic meets Shadow and Omega.
====Sonadow Moments====
On the Asteroid Coaster planet, Sonic meets up with Shadow who tests him to make sure whether he is up to the task of stopping Eggman or not. It is revealed later after you complete his mission that Shadow was concerned for Sonic's safety, which is why he tested him before he continued on his way.

On the Asteroid Coaster planet, Sonic meets up with Shadow again. When Sonic arrives, Shadow tells him that he's been waiting for him. The reason why was to give information to him about Eggman having a secret ride and that it might lead to something important. This leads to a mission where completing it takes Sonic to the control room for Eggman's amusement park. Shadow follows Sonic to the control room and voices out his complaint when he hears that the information they were able to get from the lead was not too helpful. Sonic thanks Shadow either way saying that any information is good information. When Sonic leaves, Shadow comments on how things are more quiet without Sonic around. Omega then asks Shadow why he gave Sonic the lead when he could have gone to figure things out himself. Shadow at first tries to brush Omega off by saying that he rather have Sonic do the work, but he then replies that Omega's data can't calculate everything. What Shadow is hinting is that even though Shadow is Sonic's equal, there are some things that Sonic can do better or that there are some things that Sonic should do instead (as the main character/most important person).

Shadow then makes a comment to Sonic that he shouldn't be wasting time and instead, be going after Eggman. This amuses Sonic where he playfully agrees with Shadow before leaving. When saying good-bye, Sonic only says bye to Shadow. When Sonic leaves, Shadow smiles and laughs to himself. Omega makes a comment on this asking if something was wrong, Shadow then returns to his neutral demeanor and says that it's nothing.

===Sonic Forces===
====Overview====
Sonic Forces is a game directed by Morio Kishimoto that was released in 2017. In this game, many of the 'Sonic the Hedgehog' cast appear to stop Eggman from his almost complete world domination. Characters that don't appear in this game are Cream, Cheese and Blaze. Two new characters are introduced. One is a new villain enhanced by Eggman with the Phantom Ruby, Infinite, who is a Jackal. The second is the customizable Avatar, who is the player that helps Sonic and co. fight against Eggman. After this game's release, an IDW comic, Sonic the Hedgehog (2018), was created that takes place after the game's story.
In this game, Wisp make a comeback where the Avatar character is able to use them in weapons made to have anyone use their powers without absorbing them into their bodies. This is the first game to have an Avatar character where you can make your own Original Character (OC) to join in the 'Sonic the Hedgehog' universe. This is also the only game so far to have an Avatar character.
Including free DLC, four different characters are playable in this game. Those characters are: Sonic, Classic Sonic, the Avatar and Shadow. Shadow is playable in any solo stage Modern Sonic can go to once you've downloaded his free DLC "Episode Shadow." There is also free DLC for Sonic's and Classic Sonic's Super form that you can play any solo stage with once downloaded. Each character has their own gameplay controls that are different from each other (aside from Modern Sonic and Shadow). Due to this, each of their stages are played differently depending on what character you're using. There are also stages where Modern Sonic and the Avatar work together as a team. In those stages, you can use both a Wisp weapon and Modern Sonic's boost mechanic. If you download Shadow's free DLC, you can play in extra stages as Shadow where it shows you what he was doing before Sonic got captured by Eggman and Infinite.
One other DLC available for this game is a paid DLC for a suit to put on your avatar to make he/she resemble Shadow. This suit makes the Avatar look almost identical to Shadow. Though there are free outfits you can earn in the game that resemble Sonic's friends, these outfits don't make you look nearly identical to them compared to the suit resembling Shadow because it doesn't change the avatar's body or hair like the suit does. This suit does not include Shadow's rocket shoes. To get those, you have to unlock them in the game like every other free outfit.
====Summary====
In an attempt at finding a new way to defeat Sonic, Eggman creates an item called the Phantom Ruby. With this ruby, the controller can make illusions into a reality. These illusions can even hurt whomever is influenced by it. Many prototypes were made, but a perfected version was integrated to a new character called Infinite. Infinite was a leader of a jackal squad hired by Eggman who was wiped out by Shadow when Shadow went to go check on what Eggman was doing. Because of his embarrassing defeat, Infinite held a grudge against Shadow, which led him to become the test subject to hold the Phantom Ruby. When he got his new powers, Infinite threw away his past self and renamed himself to his current name, "Infinite." With these new powers, he first tested it on Shadow before going to Sonic to defeat and capture him.
Sonic finds a new ally in the avatar. Together they fight the new enemy, Infinite, to save the world from the Phantom Ruby.
====Sonadow Moments ====
Sonic goes to find Shadow after hearing that he's been causing trouble. When he catches up to what he believes is Shadow, he asks him what his deal was. The fake Shadow doesn't answer and lunges towards Sonic in attempt to hit him. Sonic then shields himself to take the hit while letting out a whimper. At that moment, the real Shadow appears and stops time by yelling out, "Chaos Control!" He then kicks his fake away before it can hurt Sonic. Sonic is then surprised to see two Shadows as the fake disappears. Shadow comments to him that the other Shadow was a fake. Sonic then asks how or what he means. Shadow then later explains to Sonic what happened.
In Shadow's DLC "Episode Shadow," after Infinite deems that he is strong enough to beat Sonic, he hints to Shadow that he will go to Sonic to beat him up. Out of concern, Shadow asks in a worried and alarmed voice what Infinite is planning on doing to Sonic.
If you get the paid DLC for Shadow's suit, you can dress up your avatar as Shadow and have them go on stages together with Sonic. In these stages, you work together and even hold hands when making sharp turns.
===Sonic Frontiers===
====Overview ====
Sonic Frontiers is a game where Sonic goes to the Starfall Islands to discover the history about the Chaos Emeralds and about the Ancients who brought the Emeralds to Earth. This game is the first of its kind where it is an Open Zone type of game. It is also a game that has different medias tie in with it. Those medias are a short comic of before Sonic, Tails and Amy Rose arrive at the Starfall Islands, an animation of Knuckles and how he arrived at the Starfall Islands and a video from TailsTube showing what happened before the comic and animation happened.

In the TailsTube, Tails talks to Knuckles while asking about him. Knuckles goes on to tell Tails and the audience about his heritage and other things about his history. Sonic then arrives later in the video, which makes Knuckles displeased. Out of displeasure from seeing and talking to Sonic, Knuckles destroys Tails' invention with a rock to stop talking with them. Sonic apologizes for interrupting them, but Tails soon gets over it and tells Sonic about a discovery he made recently. He goes on to tell him about how he noticed that the Chaos Emeralds have been attracted to these strange islands. He then asks if Sonic would investigate what happened along with him. Sonic agrees and starts getting ready to go. Before they leave, Tails suggests to bring Amy, to which Sonic just says it's fine to bring her if he wants.
left|thumb|255x255px|Knuckles Animation that ties in with Sonic Frontiers' story
The Knuckles animation, "Divergence," takes after the TailsTube video where Knuckles goes exploring his island to find a Cyberspace portal. As he finds it, it activates and teleports him to the Starfall Islands. There he meets robots who greet him with aggression. Knuckles puts up a good fight against them, but ultimately loses once SAGE appears and gets trapped in one of the Cyber Prison Cells by SAGE. The animation ends with Knuckles enraged from this development.
The comic "Convergence" goes on while this was happening to Knuckles. Sonic and Tails go meet up with Amy to travel together to the Starfalls Islands. When they were going to pick her up, Amy is shown to be fighting some of Eggman's robots. Sonic and Tails decide to help her and defeat Eggman before they go to the Starfall Islands. As Sonic was fighting the robots, he heard Eggman say similar lines from previous games. This got Sonic questioning what was really happening. When Sonic and the rest finally beat the robots and the robot thought to have Eggman in it, it was revealed that Eggman was never there to begin with. Now more suspicious with what Eggman could be planning, Sonic and the rest decided to go to the Starfall Islands to see what really is going on. Eggman is then shown already at the Starfall Islands getting ready to hack into the Cyberspace with his new AI, SAGE. The comic ends with Eggman in front of one of the Cyberspace portals that can be seen in the Sonic Frontiers game.

After Sonic Frontiers' release, many free DLCs were available for the game. Some extra content, only available through buying the deluxe version, was also available. In one of the limited time DLCs, is the customization for Sonic's Soap Shoes from Sonic Adventure 2. To get these shoes, one had to sign up to America Sonic's news letter to get a code by email. Some other DLCs for the game are only available for the Japanese audience. Those DLCs are collaborations made with the V-Tuber Korone and a DLC emote only available through buying the lottery from SEGA Plaza.
====Summary====
Tails figures out that something has happened to the Chaos Emeralds. He learns that they're gathering on some islands called the Starfall Islands. He decides to take Sonic and Amy with him to investigate why the Emeralds were drawn there. While flying there using the Tornado, Sonic, Tails and Amy end up getting trapped in Cyberspace. Only Sonic makes it out of Cyberspace by going through a place that looks like Green Hills. It is later revealed that the Cyberspace levels that Sonic goes through in order to get Chaos Keys are based off of his memories.
Once Sonic escapes Cyberspace, a voice talks to him saying that he is the key and to destroy all the Titans. Sonic asks for context, but gets none. He comes to the conclusion that he needs to defeat the Titans in order to find and free his friends. With this goal in mind, Sonic goes to explore the first island, Kronos Island. Not long after the tutorial, Sonic sees Amy trapped in a red ball like cage while being in a holographic state. She cannot see Sonic or hear him properly, but she tells whoever the person is to save her. Sonic then says to her, whether she can hear it or not, that he will free her. He then goes to collect memory tokens in the shape of pink hearts to free Amy from her prison. Once he has collected enough memory tokens, he takes it back to Amy to free her from the cage.
Once free from the cage, Amy and Sonic converse on what is going on by recalling what has happened so far. Amy also tells Sonic how when she was trapped, everything she saw was like a kaleidoscope and that she wasn't able to hear anything. She also explains how she feels like a ghost while being in her holographic state. After telling him about her experience, they decide to go explore the island some more to figure out what is going on and to find a way to bring Amy back to normal. While exploring, Amy finds a Koco with a flower on it's head. With no explanation as to why, Amy is able to converse with the Koco. The Koco tells Amy that it wants to find it's true love, so Amy decides to help it find the other Koco. Sonic isn't eager to help, but helps anyways. This leads Sonic to going through many cutscenes with Amy and SAGE.
In the cutscenes with SAGE, SAGE asks Sonic how he got out of Cysberspace and to stop destroying things. She also tells Sonic to leave, but Sonic doesn't listen. Because of this, she summons Giganto and has it throw Sonic across the island. SAGE doesn't use it to kill Sonic and leaves him be after noticing he is unconscious. SAGE hoped that by showing Sonic the power of the Titans that he would be discouraged and leave. In the end, he does not. Instead, he decides that he needs to gather the seven Chaos Emeralds in order to go Super and defeat the Titans. He then hopes that doing that would help him free/help his friends. In order to collect the Chaos Emeralds, Sonic has to do mini games like bringing a mother Koco her children and collecting Chaos Keys to use on the Chaos Emerald vaults around the island.
In the cutscenes with Amy, Amy is going around the island with the Koco to find the other Koco it's looking for. At one point, SAGE talks to Sonic and Amy about how they are too ignorant and that love is illogical. In one of the cutscenes with Amy, Sonic convinces Amy to stop helping the Koco because getting her back to normal should be more important. Amy is reluctant at first, but agrees in the end. Though this is said, they still ended up focusing on helping the Koco due to exploring the island to find a way to bring Amy back to normal and figure out what is going on. This eventually leads Sonic and Amy to find the other Koco for the Koco with a flower on it's head. This triggers the island to go into the past to when the Kocos were still Ancients. It shows how in the past, the flower Koco went to the solider Koco on the battlefield and ended up dying together. The flashback sequence also turned Amy back to her physical form as the flashback occurred. After the realistic flashback ended, the Kocos stopped moving.
After this has happened, Sonic goes to talk to Amy and asks if she is sad about the Kocos. Amy doesn't say she is sad about the Kocos and instead talks about how what she believes she saw was love that goes beyond time. She then decides that she wants to share what she saw to the world. Sonic tells her to go ahead and do that and to tell him about it when she gets back. Amy is disappointed that Sonic is not asking to come with her, that he is not stopping her and that he doesn't seem sad to the idea of being apart from her for a long time.
Sonic then finds graves in a field of poppies that he can move. Once he moves them in the right place, a pathway to the top of the waterfall appears. Sonic goes up the waterfall and towards an open area where Giganto is. Giganto has the last Chaos Emerald that it's using as a power source. Sonic climbs up Giganto and takes the Emerald for himself. Once he has done that, a boss fight between Super Sonic and Giganto occurs. Super Sonic ends up beating Giganto by impaling it flying through it's chest at supersonic speeds. Amy appears after Giganto is defeated and tells Sonic that she feels like him defeating Giganto makes it feel like the bonds on her are lifting. With that in mind, Sonic decides that he needs to destroy the other Titans to maybe completely free his friends. He then heads to Ares Island where Knuckles is.
When flying to Ares Island as Super Sonic, Sonic gets knocked out of the sky. This leads him to lose all of the Chaos Emeralds plummet to the ground. This causes Sonic to have to work to go collect the Chaos Emeralds again. While exploring the island to find the Chaos Emeralds, he runs into Knuckles trapped in the same cage Amy was. Like Amy, Sonic decides to go collect the memory tokens shaped as medals with a star on it to free Knuckles. After collecting enough tokens, Sonic frees Knuckles from his cage.
When free, Sonic asks Knuckles what he's doing here. Knuckles tells him how he ended up there and bickers with Sonic a bit. He also tells Sonic about how it was while imprisoned. He tells Sonic that he was in a reoccuring nightmare where he was reliving the events of when his tribe was destroyed by Chaos for their greed in wanting power over and over again. After their chat, Sonic and Knuckles decide to look around the island to find clues. While exploring, Knuckles finds a Koco that was a solider. Like Amy, with no explanation as to why, Knuckles is also able to converse with the Koco. The Koco tells Knuckles how it is a solider and that he has to prepare for the battle. Knuckles decides to help the Koco because it reminded him of himself and his tribe. This leads Sonic to go through many cutscenes with both Knuckles and SAGE.
In the cutscenes with Knuckles, he talks with Sonic on how he wants to go on an adventure for once away from the Master Emerald. Sonic encourages Knuckles and tells him to go for it.
Tails is found on Chaos Island, a land that houses a volcano.
When fighting "The End," SAGE sacrifices herself to save the world.
====Sonadow Moments====
While standing idle, Sonic mentions how he would wish for Shadow's help.
Before Sonic Frontiers' release, if you signed up for the Sonic America's newsletter, you would have received a code to download a Sonic wearing Soap Shoes from Sonic Adventure 2 in the game.

===Sonic Battle===
=====Overview=====
Sonic Battle is a game that was released on December 4, 2003 in Japan and on January 5, 2004 in the US. Many don't know exactly where Sonic Battle takes place in the Sonic timeline, but due to it being referenced to in Shadow's Japanese bio on Sonic Channel (Sonic Team Japan's website), it can be taken as official/canon in some manner. The reason why many are not sure where this game takes place is due to it being released after Sonic Adventure 2, but around Sonic Heroes release and before Shadow the Hedgehog (2005). In this game, Shadow does not have amnesia and remembers everything. But in Sonic Heroes and Shadow the Hedgehog (2005), Shadow has amnesia and doesn't remember his time before Sonic Heroes until he does at the end of Shadow the Hedgehog (2005). Some speculate that there could have been a mix-up of some sorts when these games were released. But since it was referenced to and made by Sonic Team Japan, it seems that things in this game can be taken as official/canon. Meaning that how Shadow and other characters are described in this game can be taken as official to their characterizations.
Characters that appear in this game are Sonic, Shadow, Emerl, Eggman, Tails, Knuckles, Rouge, Cream and Amy.
According to the official Sonic Channel website, the real Shadow (or to see his true character) appears in this game. (To find out more, you can read the Observations page.)
=====Summary=====
thumb|257x257px|Playthrough of Sonic Battle by LongplayArchive
Eggman has discovered one of Gerald's projects; a reprogramming and discovery of an ancient ultimate robot weapon called a "Gizoid." The government has also learned of this and sends Rouge to investigate, who accepts due to personal interests. Shadow also discovers the Gizoid when he hears the Gizoid's voice, pleading him to prevent a tragedy. He follows the source to Eggman's hideout and finds the Gizoid. There, Rouge appears and explains the situation before they are jumped by Eggman's robots. After getting injured, Shadow is helped by Rouge to escape. 
Some time later, Eggman gets angry at the Gizoid for not listening to his commands and not giving back a Chaos Emerald it was given. Due to this, Eggman beats it up and discards it in the ocean. It washes up the beach where Sonic finds it. The Gizoid starts saying strange things related to it being a weapon and Sonic mistakes it for asking him to show it his power. He does so and successfully establishes a "link" with it. The Gizoid now will only listen to Sonic's commands and to whomever Sonic says for it to listen to. Sonic assumes the Gizoid is broken because it doesn't respond much, so he decides to take it to Tails to fix it. Before he does, he spots and calls out to Shadow. Shadow tells Sonic to hand over the robot, to which Sonic refuses. Since Shadow is too injured, he loses and instead, tells Sonic to keep the robot safe from Eggman. After bringing the Gizoid to Tails to fix it, Tails explains that the Gizoid is powered by Chaos Emeralds and can record attacks. Because of this, Sonic decides to call the Gizoid, Emerl.
Throughout the story, Sonic and his friends discover more of who and what Emerl is and help him train as Emerl copies their techniques. As he gains more Chaos Emeralds, he becomes more powerful, sentient, and smart being that is eventually capable of full speech. With Shadow, Emerl also learns that he is also a weapon with a heart, as Sonic points out. (Gerald created and changed weapons to have hearts because he was more interested in bringing hope to humanity rather than destroying it) When traveling with Shadow, Emerl learns from him the fate of a weapon after they defeat one of Eggman's robots. What he learns is that a weapon's fate is to just destroy whatever they are made to destroy or told to destroy. This makes Emerl sad, to which Shadow sympathizes with him. Shadow later gives his own Chaos Emerald to Emerl in order to become the "master" to imput the command: "Bring hope to humanity," (which was implemented by Gerald) so that Emerl can be free.
After being set free due to Shadow, Emerl then goes to fight everyone to show off his maturity. When he comes back to fight Shadow after fighting him once, Sonic comes to join Shadow and they fight Emerl together.
At the end, Eggman boasts that his Final Egg Blaster weapon was complete and that he will use it to conquer the world. He uses this to lure Emerl into his lair, the Death Egg. Once there, Eggman overloads Emerl with power, making him in pain and out of control. He loses his thoughts and becomes the weapon he was intended to be. He hits Eggman out of the way and is set to destroy Earth with Eggman's weapon. Sonic is given the difficult task to stop him. Once Sonic beats Emerl to his senses, Emerl realizes that he doesn't have much time left. He thanks everyone and talks about how he had fun. He asks Shadow, "Should I be glad that...I was born?" Sonic desperately tries to tell him to come back and that they'll have fun again to no avail. After a countdown of pings, Emerl disappears. Shadow sadly explains that if a weapon goes out of control, Gerald placed a program to make it terminate itself. He can't stand the situation because of how sad it is and because of the irony of how his, Emerl, and Gerald's desire is to bring hope to humanity, yet humanity (Eggman) with its selfish and greed, dashes that hope. Cream cries. Sonic tells Cream not to cry for he claims that Emerl would be in the Emerald shard left behind. Tails asks that if the world would truly learn peace, would they be able to play with Emerl again. Sonic pauses before replying with, "...Yeah! Definitely!" And the story ends.
===== Sonadow Moments =====
(Note: This is from the English translation. The original Japanese text may differ a bit.)
The cover art depicting this game is of Sonic and Shadow battling.
When Sonic reaches Tails’ house, he notices Shadow nearby and calls out his name. Shadow replies, “Huh? Sonic the Hedgehog…Sorry, but I don’t have time to play with you now.” He proceeds to talk to the Gizoid, asking if it could hear him. To Shadow’s dismay, it had already established a link with Sonic. The Gizoid remains silent. Sonic calls out to Shadow again. Shadow ignores Sonic and calls out to the robot again, focusing on preventing the Gizoid from causing harm. The robot doesn’t respond. Shadow then says, “Won’t listen to me, eh?” and says that in that case, he will destroy it with his own bare hands. Sonic tells Shadow to stop. But Shadow tells Sonic to get out of the way and to give him the robot. Here, two options appear: Yes or No. If the player picks “Yes,” Sonic says, “You didn't think I would simply say "Yes," did you?” If the player picks “No,” Sonic says, “And if I say no?” In both responses, Shadow replies reluctantly, “Then…I will destroy you too…”
After Shadow gets defeated, he tells Sonic, “Gah…I still haven’t regained my full power yet. Listen to me! Whatever you do, don’t let Dr. Eggman get hold of the Gizoid. I’ll be back… Until then, take care of it…Sonic the Hedgehog!” He leaves the Gizoid in Sonic’s care and then leaves. Sonic calls out “H, Hey! How’s Eggman involved in this?” But Shadow is already gone.
When Shadow is unconscious, he dreams. In his dream, some parts of his past, like Maria, flashes by as well as what he was doing before he went to sleep. After recounting his recent encounter with Sonic, he next sees Sonic in his dream say, “Looks like you both have one thing in common…Persistence.” Shadow then thinks, "Sonic the Hedgehog..."
thumb|249x249px|A partial playthrough of Shadow's story by MaskedMetaKnight4 that shows Sonic saying that both Shadow and Emerl have a heart despite being created as weapons.
Shadow heads to Emerald Beach and there, he meets Sonic who exclaims, “Shadow?!” Shadow asks Sonic where is Emerl. Sonic answers that he’s at Tails’ place and asks Shadow why was Shadow after Emerl. Shadow says that he’s not there to steal him, but to welcome him as a fellow weapon of war. Sonic questions this. Shadow asks if Sonic has noticed that the Gizoid, a weapon, awakening is near. Sonic further questions. Shadow then asks if Emerl already has six Chaos Emeralds. Sonic confirms. Shadow says that with his own, it will make seven. He then says that its true power lies dormant, but he can feel a greater power that is dormant, a greater power than Sonic can imagine. Sonic replies saying that he heard that he who collects seven Emeralds will be granted unlimited energy. Sonic then asks if Shadow was telling him that awakening Emerl is dangerous. Shadow scoffs saying that he’s a weapon that’s strong enough to destroy the world. Awakening him is sheer madness! Sonic says in response, "I don't think he has it in him. The Emerl I know would never destroy the world." Sonic then asks "What about you?! You say he's the ultimate weapon, but weren't you supposed to be the military's ultimate secret weapon?!" Sonic further adds, “Maybe you’ve forgotten, but I seem to recall you saving humanity at some point.” Shadow slowly says that that was for Maria. Sonic then says, Shadow responds with a tsundere “Hmph!” and says "No, you are wrong. We were created as weapons. If the people of this world ever want peace, they must destroy us.” Sonic calls out Shadow’s name, taken aback by such a thought. Sonic adds that Rouge said that there’s a key word that can free Emerl. If they can figure out what it is, Emerl can become a normal robot. Shadow replies, “Ha! Such hopeless dreams… Weapons have no need for a conscience. Freedom? What use is a weapon that does not follow orders?! I have a different kind of “Link” with Gizoid. Like me, he’s a weapon! No doubt about it! He’s a weapon to be used by his “Master!” Sonic sadly replies, "Shadow..." Sonic then gives in and tells Shadow to just take Emerl already. If he wasn’t going to listen to him, then he can do whatever he wants. Shadow replies with a simple, “…Yeah.” Shadow then asks if Sonic didn’t care if he exterminated Emerl. Sonic comes back with a “I’d like to see you try!” Shadow asks "You don't think I could?" Sonic replies with, “ Maybe you guys should just play games together or something?” Shadow stays quiet. Emerl then arrives, saying that he senses a Chaos Emerald. Sonic asks what Emerl was doing here. Shadow says that he probably felt his Chaos Emerald, and that he can feel it resonating with him. Emerl points out that Shadow has an Emerald. Emerl demands that Shadow hands over his Emerald for he wanted power. Sonic tries to snap him out of it by calling his name. Emerl snaps out of it and asks Sonic what’s wrong and why he was looking at him like that. Shadow states that perhaps now Sonic would believe him that Emerl was created as weapon and says that Sonic was lucky that he met Emerl before he awakened, but he cannot deny the Gizoid’s true identity. Emerl questions Sonic. Sonic then tells Emerl to go with Shadow because he wants Emerl to find out who he truly is. Emerl asks how. Sonic says to get Eggman to tell him. Emerl replies, “That chubby old guy? That sounds like fun! I’ll be right back then!” Sonic says okay and to see if he can find out more about Eggman’s weapon and plan that Knuckles was talking about. “You can never tell what that old man is planning!” Sonic says. Shadow adds that he, too, has things that he would like to speak to Eggman about. Shadow then says, “Let’s go, Emerl. So begins our path to ruin.” Before leaving, Emerl tells Sonic to tell Amy that she has to exercise and eat a specific way for her training regimen. Sonic laughs and says, “Some ultimate weapon you are!”
Due to both Sonic and Shadow having a type of established "link" with Emerl, one could say that they are both Emerl's "dads." Sonic activated a link with his power while Shadow has a telepathic link and later on, becomes Emerl's new "Master" from inputting Gerald's code to free him.
After Shadow inputs the code, "Bring hope to humanity" into Emerl to free him and Emerl processes it, Emerl says “Hey, now! Don’t go and get all serious on me like that, Shadow!” Shadow responds with, “Hmph. Look who’s talking. You remind me a little too much of a certain spikey, smug little…” Emerl stops him with, “Watch your mouth!” Shadow stops and tells him that he’s free now and that Eggman will no longer have any control over him.
After Emerl beats Shadow in a test of strength, Shadow says “Heh…I shall concede that you are my equal." Emerl replies with, “Hey, man! I’m just getting warmed up!” Shadow comments, “Hmph. You’re just as mouthy as him, too.” He further says, “Looks like we’ve got a guest. Come back later.” Sonic appears and greets Emerl. Emerl responds by calling out Sonic’s name. Sonic says, “I figured Shadow wouldn’t be able to give you enough of a challenge by himself, so I came!” Shadow comes in and says, “Yep, you sound exactly alike.” Sonic then says, "Whaddya say, Emerl? You wanna take us both on at once? It’ll be tough!” Emerl says “No problem! No problem! … … … No holding back! I hope you two don’t get hurt!” Emerl fights both Sonic and Shadow together.
After Eggman tricks Emerl in order to control him, the scene flashes to Sonic and Shadow who are standing next to each other. Sonic is shocked, saying “Hey, Emerl…, oh no!!” Shadow then says, “No! Now I understand what’s going on. The Doctor planned this all along!!” Emerl speaks in binary, causing more concern from Sonic. Emerl then starts to speak like a weapon again. Eggman explains that there was one link they didn’t know about. The link is activated when faced with someone with overwhelming power. The power is overflowing within Emerl and he can’t contain it. He calls out to Sonic and Shadow first for help, saying that he’s in pain.
After thinking of using the Master Emerald to calm the Chaos Emeralds in Emerl, Tails tells Sonic that the transporter is ready. Shadow, overwhelmed, sad, and feeling that he's no longer qualified, says, “I am…no longer… You must go…Sonic…” Sonic sympathetically says, “Shadow…”
After defeating Emerl, Emerl questions where is here. He asks who is himself. Next, he says “Sonic…the pain…” Next, “Shadow…Dark…” Emerl then asks if he is going to die. All the while sparking and shaking. Sonic tries to call out his name. Emerl weakly calls out Sonic’s name. Sonic asks if he’s all right, but Emerl says nothing. Sonic asks if he can walk and for them to return to Earth. Emerl instead says that it has been fun and thanks Sonic. He says that it is goodbye and that he’s glad that he got to see everyone one last time. He pauses before asking if Tails had gotten stronger and that he knows he tried his hardest to protect him; to thank him for him. He then says he had so much fun with Knuckles even though he was gullible, but that he’s such a good guy so don’t tease him much. He then says Mom (a title Amy forced him to call her) and Cream, looks like this is goodbye. He doesn’t want to go and he’ll miss all of them. He then asks Shadow if he should be glad that he was born. Sonic tells him not to play around and get so serious on him, if he thinks that this is goodbye. In desperateness, Sonic tells him, "Let’s go play." That everyone is waiting for them back home. “Tails! And even Shadow and Knuckles!” Sonic starts breaking, saying that they’ll go mess with Knuckles again and that they’ll go home and laugh and all have a good time. He tries to ensure Emerl. Emerl is silent before countdown of pings goes off. He disappears, which Sonic states. Shadow then states, “This was Gerald’s final program. Should a weapon go out of control, the weapon will terminate itself…” Shadow pauses and then sadly adds, (What Shadow means by these lines is that it's ironic that Shadow, Emerl, and Gerald's desire is to bring hope to humanity, yet humanity itself dashes that hope with its greed and selfishness; that greed and selfishness of humanity is what he can't stand.)

====Sonadow Moments====
At the end of the figure skating routine, if you do the pose correctly, Shadow will make the iconic Sonic Adventure 2 pose that's on the cover of the Sonic Adventure 2 game.
In the shopping area, there's a chance for Sonic and Shadow to interact with each other as they walk through the plaza. When they interact with each other, they will wave to each other, then talk to each other. When talking to each other, three different actions occur. They will either wave their arms around in an exaggerated manner to mimic talking, put their hand under their chin in a thoughtful manner or just nod. When they're done talking to each other, they will wave good-bye and walk away. Sonic waves in the usual manner towards others while Shadow does a still wave. If the two do not interact with each other in a conversation when coming into contact with one another, one might stare at the other as they walk away.
There are several activities where you can choose to play as a team. When choosing a team, you can put Sonic and Shadow as one of the four team member options. Though in party games, you can choose to be a team of two or be against the other characters chosen.
You can customize the sports gear you use in the Olympic activities. When customizing the gear, you can add either a Sonic or Shadow sticker and/or banner to it to make the sports gear have both Sonic and Shadow on it.

===Team Sonic Racing===
====Overview====
This game was released in 2019 and was made by the studio Sumo. It is not a game created by Sonic Team, but it is considered a spin-off that is official to the canon timeline like the Sonic Riders series. This is shown by it being mentioned in the character bios from Sonic Channel. The cars that come from the game are also brought up again on occasion in official Sonic materials.
====Summary====
Sonic, Tails and Knuckles get invited to do some races by a mysterious invitation. When going to the location in the letter, he meets Amy, Big and several Chao having a picnic near the beach. When explaining why he was there, Amy comments on how she was not invited. Dodon Pa then appears and introduces himself. After some explanations, Big wanted to join the races, which Dodon Pa let him do. Hearing this, Omachao and Amy decide to join Big to be a team together. Even after finding him suspicious, everyone agrees to go along with Dodon Pa's wishes and join in the races. Sonic is the most excited about these races and Big is the only one who doesn't think Dodon Pa is a bad person. Dodon Pa also promises the team that wins the tournament being able to keep their car.
After a few dangerous races, Sonic's friends are getting more and more suspicious of Dodon Pa to the point that they think he's working with Eggman. There's no proof of this being true, but they find his word choices, the way he laughs and the mysterious air around him as reasons to find him suspicious. They continue to keep an eye on Dodon Pa as they go through his dangerous races. Tails even goes through the effort to ask for outside help to look into Dodon Pa for him.
Eventually Silver, Blaze and Vector appear due to their own circumstances. Silver and Blaze were invited by Dodon Pa, but Vector was not and says that he knew of the races due to his source. Silver and Blaze were about to refuse to join the races, but decided to join in a team with Vector due to Vector wanting the cash prize.

In mostly all of the menu screens it has Sonic and Shadow. The screens that have the both of them on it are: the Start-up screen, the Main Menu screen, the Garage selection screen, the Local Play selection screen and the Options screen. For the Main Menu screen, Shadow is hard to see in the background due to being blurred. To notice him, look for a blurred image that shows a car using a Rocket Wisp in the background.

Throughout almost every racetrack are balloons of Sonic and Shadow. The only place they do not appear is on the tracks from Eggman's base.
If you're playing with a friend, you can choose to have both Sonic and Shadow in a team together by each player choosing either Sonic or Shadow. If you don't have a friend to play with, you would have to get either Sonic or Shadow in your team by chance.

(Note: The following dialogue scene moments are from the English dialogue. The original Japanese dialogue scenes at times, contain different wording.)
When playing in races, sometimes the characters will say things to other characters. Times this occurs is when a character hits another character, when the character gets hit by another character, when a character helps another character or when a character is doing poorly. In the lines said, there are several lines that Sonic and Shadow say to each other.

When Shadow first appears in the story, Sonic volunteers to go talk with Shadow to figure out why he was there. At first Sonic teases Shadow by commenting on how he showed up and by teasingly asking if he's there to win or do Eggman's bidding again. Shadow responds to Sonic saying that he always tries and always succeeds. He then continues and mentions that he isn't there for Sonic, despite Sonic not mentioning that he was. He also seriously answers Sonic's question by saying that he is not working with Eggman and that he's here to stop his evil plans too. Sonic continues to tease Shadow by taunting him that he can't beat him anyways. He also mentions in a still teasing manner that while he's at it, he will stop Eggman for Shadow. Shadow comments on this saying that as the Ultimate Lifeform, he can't lose to Sonic. Sonic takes on the challenge and suggests that they race to see who is the best. Shadow accepts this challenge and they then go to race each other along with other characters.
*Sonic chose to go talk with Shadow on his own volitation. He also did it with only himself, which made him have some alone time with Shadow.
*Sonic knows that Shadow doesn't work for Eggman anymore and says this just to tease him. Though Shadow takes it seriously and answers him for a straight forward reply that he is not working with him and wants to stop him.

When Sonic gets back to his team after talking with Shadow, Tails asks Sonic if he got anything from Shadow. Sonic replies in a amused manner after a slight laugh that Shadow thinks he's faster than him. Tails gets confused by Sonic's answer and clarifies that he meant that if he got any new information about Eggman from Shadow. Sonic realizes that that's what Tails meant and replies that Shadow is here to stop Eggman too, so no.
*When Tails asked Sonic about Shadow, Sonic's first thought was about Shadow and how he's racing/playing with him. By how Sonic replied when Tails clarified himself, it is shown that Sonic is more interested in racing with Shadow than the "problem" that was going on.
*The problem was something that Sonic wasn't worried about due to being sure he can fix it whenever, but the rest of his friends were worried about it, which is why they kept on telling him to do something about it. Though because of this, Sonic paid attention more to Shadow and his races with him than the problem concerning Eggman. Therefore, most of his attention throughout the game was on Shadow.

After their race, Shadow says to Sonic that he may be useful in helping him stop Eggman. Sonic says that's nice of Shadow to say, but also mentions that Eggman might not be the only one they have to watch out for. Shadow agrees and says that Dodon Pa is a mystery, but he reassures Sonic that if Dodon Pa is working Eggman, he will deal with him too.

Before they do a Grand Prix for chapter 3, Rouge asks Sonic and Shadow if they were done with their little ego-competition so that they can focus on the bigger issue (Eggman and Dodon Pa). Both Sonic and Shadow reply to Rouge at the same time, "We're far from finish!" Rouge then says to them, "Ugh, you boys."

We must figure out how we can defeat Eggman." Afterwards, you can then play as Shadow by choosing him in your character inventory.

During this event, the picture used to advertise the event is of Sonic and Shadow next to each other racing towards the viewer. Sonic is looking towards Shadow in this image. The icon for the event is also the same but with a slightly different background.
To get these outfits, you need to do the specific City Escape races either alone or with others. Completing races will give you Race Tickets that can be used on the wheel to have a chance to get either Racesuit Sonic or Racesuit Shadow. The chance to get them is 2.3% separately. While this event is going on, there is a section in the game that showcases the outfits. In that display, Racesuit Sonic and Racesuit Shadow are next to each other. Due to their idle motions, Shadow can be seen looking at Sonic during his idle motion sometimes.
During this event, both Sonic and Shadow Chao were on sale. Riders Sonic and Riders Shadow were also on sale and next to each other. A new wheel where you can win outfits for free was also added the same time this even started. The outfits that can be won in this new wheel are Android Shadow Pink and Summer Sonic.

On this wheel, you have a chance to get the Fake Metal Sonic skin or the Android Shadow Pink skin. During Racesuit Jet's event, you can complete his quests to not only get his outfit, but also Race Tickets. With those Race Tickets, you can buy Racesuit Sonic and Racesuit Shadow who were still in the shop at the time. Also, during this event, Sonic and Shadow Chao were still on sale.
On August 5th, Red Android Shadow was made available to get by completing a quest in Sonic Speed Simulator.

The icon used to look at the quests is an image of both Zebra Sonic and Cheetah Shadow together.
During the winter of 2023, Winter Shadow was added to Sonic Speed Simulator. To get him you have to get 1500 race tickets. Winter Sonic was available in the past before the game got updated.
In a bundle sale that uses real currency, many characters were bunched together as a set. Among the set is the Gold Style Sonic and Shadow. When showing the bundle as either an icon or as 3D models in the store, both Sonic and Shadow were in the front next to each other.
===== "Fast Friends" Toy Robots =====
On November 9, 2023, Sonic Speed Simulator announced a new system called "Fast Friends" that introduce Toy Robot versions of Sonic, Shadow and Knuckles into the game. In the game, you can get these Toy Robots by a vending machine that uses Red Star Rings. Once you get enough, you can fuse them together to upgrade the Toy Robot of choice. These Toy Robot act the same as friends you can equip like Chao, Animal Friends and Kocos. When you equip them and run with them, they run along with you. If you stay in place, they do an idle motion. The Toy Robots start at a 1 star rarity and can be upgraded up to 5 stars. As you upgrade them, they change color and shape.
The way they change shape and color goes as so:
*1 star | Looks like the character it takes after
*1 star → 2 star | Fur changes to a silver coating; a silver sparkling trail follows them
*2 star → 3 star | A silver glow is added; they increase in size
* 3 star → 4 star | Fur changes to a gold coating; aura changes to purple and yellow; sparkles radiate off of it
*4 star → 5 star | Aura changes to gold and orange; grows in size

During the event that introduces this new function, a new outfit for Tails was introduced. In the display that shows this outfit of Tails is a table that has the Toy Robots on them. On one of the tables it has the Sonic and Shadow Toy Robot versions with a stack of Red Star Rings.
The Icon used for this event is of Sonic looking at a Toy Robot version of himself and Shadow. Both are looking back at Sonic with a happy expression.
For the Holidays in 2023, Holiday themed Toy Robots were available for a limited time at the Christmas Store where you trade candy canes for several rewards. Among those rewards there was a Holiday Sonic and Shadow Toy Robot. Both share a similar outfit where they both wear a Santa hat and top. Shadow's top is slightly different where he has no sleeves compared to Sonic. A Super Sonic Toy Robot was also available at the store. All Toy Robots can be upgraded the same as the regular Toy Robots.
Since an update, Fast Friends vending machines appear in certain worlds. Sonic's Fast Friend is in the first world while Shadow's is in the second. You can try to get Sonic's for 10 Red Star Rings and to get Shadow's you need to use 20 Red Star Rings.
