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.

(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 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?”

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!”
