On July 8, 2019, Sonic America posted a video for Team Sonic Racing. This video was made in an animated papercraft format. The video is related to the other animation Team Sonic Racing: Overdrive by having the same cast as the other animation. In the video, it focuses on Dodon Pa having a daydream about the race will go. His daydream begins with Sonic and Shadow competing with each other. After some time, Shadow lays back in his car seat in a nonchalant manner while slowly driving ahead of Sonic. Sonic takes notice of this and glances towards Shadow. Sonic gets upset at this and pulls ahead of Shadow. Shadow then stops relaxing and goes back to driving his car normally. Once he drives normally, he picks up an item box that has the Cyan Wisp in it. He uses it on Sonic and pulls ahead of him a great distance. Sonic's car flashes for a second to show a different design before he collects an item box as well. When Sonic picks up the item box, what was in it was a chili dog and it turns his car into a chili dog car. Sonic is happy about this and eats a little from the car. After driving a short distance, a killer whale jumps out of the water in front of Sonic. Suddenly, Sonic pops into existence at the goal for a Green Hill's stage where his Classic self on a goal sign is. Sonic runs up to the goal sign and then there's suddenly an explosion. The panel then zooms out to show that all of that was Dodon Pa's imagination. As he was imagining this, Sonic is standing in front of him waiting for the race to start. He snaps Dondon Pa back into reality and then gets back into his car. Dodon Pa then counts down and the racers take off.

==== Twitter Takeover ====
On November 2, 2017, in celebration of the release of Sonic Forces, a Twitter Takeover with Sonic, Shadow and Eggman was held. In the welcoming video, Sonic often teases Shadow and even teases him that he's better than him to make him stay.
For Twitter Takeover #3, @JoannaWhiteRose asks Sonic: "To Sonic, I have a challenge for you. Tell me how much you like Amy and what do you like in her?" Shadow asks Sonic this question for @JoannaWhiteRose in a teasing manner. Eggman joins in after the question is asked and pressures Sonic to answer the question. Sonic is reluctant to answer saying that there are many other questions to choose from. Because Sonic is trying to avoid the question, Shadow asks Sonic is he's too embarrassed to answer and Eggman agrees that that must be the case. Eggman then receives a message from Infinite that is of a file named "Sonadow." When Sonic hears this, he panics and tells Eggman not to open it.
* This is the first time Sonadow has ever been officially recognized by SEGA.
* Despite the question asking about what Sonic likes about Amy, the answer shifts over to being focused on Sonadow.
* Because Sonadow was brought into the answer, you can assume that the answer means that Sonic is more interested in Shadow.
* Though Sonic is assumed to be embarrassed when answering this question by Shadow, Sonic was more concerned about Eggman and Shadow seeing photos of him with Shadow. You can take this as him being embarrassed due to his panicked state when Eggman received the file. This can be because Sonic doesn't know how Shadow feels about him or that he's afraid to hear what Shadow thinks about it. If he wasn't worried about how Shadow and others would see him from looking at Sonadow images, then he wouldn't have been as panicked as he was.
For Twitter Takeover #3, @Cassidy12051131 asks Shadow: "What do you think of, Sonadow?" Shadow replies by saying, "One word Cassidy... No."
* Usually when it comes to ship names, the one who is first in the name is the one who is the dominate one in the relationship. Due to Sonadow having Sonic's name first, this could be a reason why Shadow said no because Shadow would like to be seen as the dominate (or top) one in the relationship. Though, Shadic is the term for the fusion between Sonic and Shadow and cannot be used as their ship name. But, ShadSoni is also a term used by those who like the relationship between Sonic and Shadow. ShadSoni is mostly used by Japanese fans back in the day.
* Sonic stays quiet during this question. The reason can be because of how Shadow replied.
* Though this was said back in 2017, things have changed in future Twitter Takeovers where Shadow and Sonic show more interest in each other than when this Takeover happened.
For Twitter Takeover #3, @_KaineMorales asks Shadow: "What was it like being the Ultimate Lifeform?" When this question was asked, Eggman was the first to question what the person meant by "was." Shadow then comes in and tells the person to not test his patience and that he is the Ultimate Lifeform. He goes on to ask the person if he is implying that there is someone strong than him, and if he is, then he will hunt him down and prove just how much he is the Ultimate Lifeform. Just as Shadow was saying this, Eggman cuts in saying that there is Infinite who could be a competitor as the Ultimate Lifeform. Sonic adds to this saying that Infinite's theme song is more edgier than Shadow's. When Shadow hears this, he is disappointed that even Sonic is saying that someone else can be the Ultimate Lifeform. Because of this, Shadow states that he will just get rid of everyone then. Afterwards, he exclaims "Chaos Spear!"
* From this question, you can take that Shadow had more faith in Sonic to have his back when he was disappointed that he was siding with Eggman/Infinite. Meaning, he trusted Sonic to be there for him or at least believe in him to be the Ultimate Lifeform like it is said he is.
For Twitter Takeover #3, @megaman765 asks Shadow: "Dear Shadow, can you possibly act happier than Sonic? Win this challenge, and you may have that 4th Chaos Emerald." Sonic adds his commentary first by scoffing and saying that Shadow trying should be something entertaining to watch. Shadow then accepts the person's challenge and smiles. Eggman then whispers to Sonic asking if anything changed because Shadow looks the same. Before Sonic can answer, Shadow responds by saying that you can't hear it, but he's smiling. He continues on saying, "I am oh so happy. Sunshine and rainbows... unicorns and kittens... adorable... puppies..." Sonic then lightly laughs at Shadow's response. Eggman then says that at least Shadow tried.
* Sonic laughs in a cute manner when Shadow tries this challenge, to which Shadow doesn't say anything against it. Sonic could be laughing due to Shadow being cute from trying so hard to be happy in order to get the 4th Chaos Emerald.
In the ending video, Sonic starts by saying that there was a lot of questions, but that it was also a lot of fun. Eggman says to Shadow that it wasn't so bad after all. Shadow responds to this by admitting that it was a little amusing to do with them. Sonic then responds saying that Eggman almost made Shadow smile, but Sonic quickly tries to take back what he said in fear of others making fanart of that. Eggman is confused by Sonic's actions, to which Sonic was about to explain what he meant, but he voted against it and decided to tell Eggman that it's just better if he doesn't know. Shadow then intercepts their conversation by thanking the audience for joining them today and saying that he may finally understand what the people of the world want. Eggman questions if it's destruction or evil dictators and Sonic asks if it's a chance to be happy. Shadow denies it's any of those things and says that they he believes that the people want a new video game staring himself in it with no Eggman or Sonic around. Shadow then emphasizes on it just being him, but then also adds that it will be with his new sidekick Big the Cat. Sonic and Eggman groans at this. Eggman then changes the conversation by saying that they had a good time and that he hopes that the audience did too. He continues on telling the audience to be sure to follow his conquest for world domination on Patreon and to smash the like, comment and subscribe button. As Eggman was saying this, Sonic cuts in saying that this is Twitter and that there is no subscribe button. He then asks Eggman if he just took those lines from a YouTuber. Eggman denies Sonic's claims. Shadow then comes in and says that Sonic Forces will release on November 7th (2017) worldwide. Shadow then reminds the audience that once they own a copy of the game that there are free DLCs that can be downloaded that feature him in three levels. He continues on saying that he believes that these are the best levels in the game because it has him in it. Eggman then says that the audience can play the main story and see him finally take over the world. Sonic makes a comment on what they said by calling them cute. Sonic then continues on by saying that the real point of the game is taking back the world. He continues on saying to join him, Classic Sonic and to make your very own character in order to save the world together. When he mentioned Classic Sonic, Sonic makes a comment saying that Classic Sonic doesn't talk much. Shadow then thanks the audience again for their time and questions and adds that he hates them all a little less now. Eggman then adds to his saying that on behalf of everyone that they all hope they enjoyed themselves. Sonic adds to this saying that they hope they have a happy Friday and that they hope they enjoy Sonic Forces. Lastly, they all end the video by telling the audience to take care.
* In the ending video, Sonic calls Shadow (along with Eggman) cute.
center|thumb|450x450px|Twitter Takeover #4 from Sonic America
On May 24, 2019, in celebration of the release of Team Sonic Racing, a Twitter Takeover with Sonic, Shadow, Tails and Eggman was held. In the welcoming video, Shadow asks Sonic why the hashtag to ask the questions isn't #AskShadow. Eggman and Tails join in saying they want the hashtag to be their names. Sonic tiredly responds that it will just be #AskSonic and says that they too can answer. They all grumble from this. He goes on to say for people to ask them questions using #AskSonic. When Sonic is done, Shadow makes a small complaint saying that it really should be #AskShadow.
For Twitter Takeover #4, @smoov22_sonic asks: "What is Shadow's favorite place to go shopping?" Sonic answers first saying that it has to be the store with all the edgy and goth things in it. He tries to remember the name and says that it's called something like "Lukewarm Topic." (Sonic is referring to Hot Topic.) Eggman then answers saying that he thought it was at the Halloween store because he saw Shadow wear a cape once. Shadow then intervenes saying that despite those two places being good establishments, where he goes to get his clothes is at the local convenience store called, "Maria's." Eggman and Tails both gasp at this. As Tails was about to ask if Maria was who he thought he was, Sonic cuts in by trying to apologize to Shadow, but Shadow reassures him that it's okay. He continues on saying that at least helping a Maria out there helps him feel like he's making the world a better place. Eggman then hesitantly replies saying that this answer was quite the emotional rollercoaster and ends it by thanking the person.
* Sonic is considerate of Shadow's past and emotions. He also cares for his well-being because he knows that Maria was close to Shadow and that she passed away in a horrific manner.
For Twitter Takeover #4, @TheHaasManWyatt asks: "What is you all-time favorite memory?" Sonic responds first saying that it was the time everyone saved the planet together, He gives more context saying it's the time with the BioLizard. (This is hinting to Sonic Adventure 2.) Tails then responds saying that it's when he met Sonic and when he went on his own adventure on Coco Island. Eggman answers saying that it's when he finally beats Sonic, to which he insists happens all the time. Eggman then asks Shadow what his favorite memory is. Shadow then responds by saying it was when he was dead. Sonic is the first to comment on this by saying that things got dark. The answer to the question abruptly ends there.
* Sonic says that his favorite memory is the one he had with Shadow when he first met him. Shadow also mentions his time in Sonic Adventure 2 being his favorite memory/most memorable adventure in the next Twitter Takeover.
* What Shadow could be referring to when he says that his favorite memory was when he was dead is his sense of accomplishment when he saved the world with Sonic. In the end of Sonic Adventure 2, Shadow asks if he did the right thing to Maria. In that moment, he was content that he made a difference and saved the world.
For Twitter Takeover #4, @snowcanine asks: "If you guys could change one thing about yourselves, what will it be?" Sonic answers first by saying that he would like to know where the Chaos Emeralds are at all times because it would make stopping Eggman much easier for him. Tails responds that he would like to never get tired when flying. Eggman says he'd like to get rid of the mercy in him because it gets in the way of him destroying Sonic to finally conquer the world. When Shadow answers, he says that he wouldn't change a thing and that our mistakes make up we you are. He continues by saying that he's comfortable with himself and with who he has become. Sonic responds to this saying that he finds that Shadow's answers are either the most depressing or the most inspiring depending on the question.
* From this you can say that Sonic finds Shadow inspiring on certain answers like this one.
For Twitter Takeover #4, @Lisamellow1 asks Sonic: "An innocent question for Sonic, if he doesn't mind. I have read in a book that it is confirmed by Sonic Team that Sonic has feelings for Amy but he is too nervous to admit it! So is that true~? Also, have this very quick doodle of Amy I made." Tails is the one to ask Sonic this question in a rather harsh teasing manner. Eggman responds to this first wondering if it's true. Sonic is put off guard and is questioning why they are asking him about Amy all of a sudden. Tails responds to this saying that the fans just want to know and that Sonic said that they could ask him anything. Sonic then studders are he says that he's not comfortable talking about that. Shadow makes a remark at this asking Sonic if he's afraid and if he's now running away from his feelings too. Sonic exclaims that he doesn't want to answer it and then leaves abruptly. Tails comments that Sonic doesn't usually act that way, but he also comments that he knows that for sure the Sonamy fans are going to go nuts from this response.
* The book that is being referenced in this question is not an official book that is licensed by SEGA. It is a book from Disney that could have no connection to SEGA or Sonic Team or it could be of an interview of members from SEGA that no longer work for SEGA like Yuji Naka or Naoto Ohshima. It could have also been fabricated since the book cannot be found today and because Sonic Team has said in more recent materials that this is not the case.
* The ones who are trying to push that this question is for Sonamy fans is the Sonic America social team, not Sonic Team. Sonic Team did not work on this Twitter Takeover in any manner.
* The person asking this question says that this is an innocent question for Sonic, but all Sonic fans are aware that anything related to shipping is not taken lightly. Meaning that this person asked this question knowing it wasn't an innocent question.
* Shadow is shown to be concerned for Sonic's panic by asking him if he's afraid and trying to run away. What Shadow could be referring to here is if Sonic is afraid to admit that what the book says or that him having feelings for Amy is not true due to not wanting to make others mad, like Amy. This is further confirmed in the future where Sonic shows to have no romantic interest in Amy in future content. He only sees her as a friend, which is confirmed by Sonic Team in 2022.
In the ending video, Tails starts by saying he's surprised and exhausted by all the questions. Eggman reassures saying that he should get used to it because it's always like this. He speaks from years of experience. Shadow makes a comment saying that Eggman is upset because he didn't get as many questions as everyone else. Sonic cuts in saying that he sees that more questions are coming in, but he adds saying that there's no more time to answer them. Tails continues this thought saying that they have to stop at some point. He then goes on to thank the audience for letting them answer their questions and that he's thankful to be invited this time. Eggman then thanks his fans and Shadow adds to Eggman's statement by saying, "and to the supporters of the world's greatest hedgehog." Sonic takes this as Shadow saying that he's the world's greatest hedgehog, but Shadow corrects him by saying he meant himself. Sonic then calls that being typical of Shadow. Eggman then comments that for all the questions they didn't answer, they would have to come back for another Takeover to answer them. Sonic is surprised by this and says they just finished the 4th one. Tails then interjects by agreeing with Sonic, but he also adds that someone else should be invited too, like Rouge, Big or Amy and maybe Cream. When Sonic hears this, Sonic starts to panic again and tries to tell Tails no, but Shadow intervenes saying that everyone appreciates the audience taking the time to hang out with them. Sonic then recovers from his panic due to Shadow covering for him and also thanks the audience. Tails and Eggman follow suit. In the end, Shadow yells out "Chaos Control!" as he leaves.
* Due to the other question asking about Amy, Shadow knew that Sonic wasn't comfortable about things concerning Amy, so he covered up for him so that he wouldn't have to panic again. This works as Sonic quickly recovers from panicking from what Tails suggested.center|thumb|450x450px|Twitter Takeover #5 from Sonic America
In celebration of the release of Sonic Colors: Ultimate, a Twitter Takeover with Sonic, Shadow, Tails, Eggman and Yacker was held. For this Twitter Takeover, both English and Japanese worked on the answers.
For Twitter Takeover #5, @Epic_STARS asks the cast: "What is everyone's most memorable adventure?" Yacker answers first by saying that it was meeting both Tails and Sonic. Sonic is happy with Yacker's answer and says that Tails and him do make quite the impression. Eggman answers next by saying his is breaking a wall of ice on Planet Hex (In Lost World) in front of Sonic. Eggman asks Sonic if he remembers, and Sonic reluctantly answers yes. Eggman than goes on to boast about his power from being able to destroy the ice wall without it hurting. Shadow then says that his most memorable adventure was when Sonic reached out his hand to save him before he fell to earth after the battle they had against the BioLizard (He is referencing to Sonic Adventure 2): "Sonic reached out to save me before I fell to earth from the ARK. If I hadn't waved him away, Sonic would have fallen with me... But his determination in trying... I'll never forget that... Until I did, but we're not going to talk about that." (He is referring to the time he got amnesia after he fell to earth from the ARK. But he regains his memory later hence why he remembers this scene now.) Sonic is touched by Shadow's answer and replies by saying Shadow's name in a soft manner. Tails then goes on to say that what Shadow said was really sweet. Eggman then comments on how he feels bad for boasting about his muscular fist after Shadow's answer. Sonic then ends things by saying that their most memorable adventure is yet to come and then he thanks the person.
* Since this is Shadow's most memorable adventure, you can say that meeting Sonic is one of the best memories he has in his life.
* Sonic's reply to Shadow's answer can show how touched Sonic is to know that Shadow remembers his efforts. You can say he is also happy to know that Shadow remembers and that he is part of one of Shadow's fondest memories.
* Shadow waving away Sonic's hand to save him shows how much Shadow cares for Sonic and his safety, even at the cost of his own.

In celebration of the release of Sonic Frontiers, a Twitter Takeover was held with Sonic, Shadow, Eggman, Knuckles, Tails and Amy Rose.
For Twitter Takeover #6, @bryan_hedgehog asked Sonic and Shadow: "To Shadow and Sonic, do you hate each other?" Amy nervously laughs saying that there's no way that Shadow hates Sonic, but she ends her sentence with a question due to not being sure on whether Shadow hates Sonic or not. Sonic then taunts Shadow asking him if he hated him or not: "Yeah, what do you say, Shadow? Do you hate me?" Shadow answers Sonic in a sarcastic and teasing manner: "Hmmm.... Well, let's see... Your methods are usually annoying, your jokes fall flat, your skills lack discipline, you constantly see the best in people to your own determent, and you have terrible taste in footwear. But no. I don't hate you." Tails is the first to respond and to reassure Sonic by saying: "You hear that Sonic? Shadow doesn't hate you!" Sonic stumbles on his words in disbelief: "Wait but- but, he said so many mean things..." Amy then reassures Sonic by reiterating that Shadow doesn't hate Sonic. Knuckles then compliments Shadow and says that he has his respect to admit that he doesn't hate someone. Sonic is still in disbelief and stumbles on his words again only to get cut off by Eggman who says: "Happy to have settled that once and for all. Thanks for the question, bryan hedgehog."
* From this question, you can take it as even though Shadow says things in a harsh manner, he doesn't hate Sonic. You can say that him being harsh at times is part of his Tsundere personality.
* You can also see that Shadow keeps a close eye on Sonic to be able to list so many detailed things about Sonic. That means he's paying a lot of attention to Sonic. Also that he cares about Sonic enough to warn him not to trust others so easily because he can get hurt from it.
* Another thing to note is that it is never said that Sonic hates Shadow, meaning he never hated Shadow before. It is only questioned by many on whether Shadow hates Sonic due to his harsh personality.
* Shadow teasing Sonic could hint at Shadow being friendly enough with Sonic to mess around with him. It shows that their relationship with each other isn't so stiff or sharp, but rather friendly in their own way.
For Twitter Takeover #6, @RealShadowFan01 asked Shadow if he would marry her. Sonic, Tails, Knuckles and Eggman all teased Shadow about the question, but they were all shocked when Shadow said that he would. Sonic then asks Shadow in a dejected voice if he was serious: "Are- are- Are you serious?" Shadow answers saying that he would only marry the person if they can follow his strict set of rules. If they are able to do his tasks, he said that he would propose himself. He lists out three tasks that the person would have to follow beginning with: "I iron my linens every night. I refuse to go to bed in a wrinkled bedsheet. Anyone who wants to be my partner, must be able to assist." Sonic replies in a confused manner: "Okay, a bit peculiar, but I can understand." Shadow then goes on to list the other two tasks and says that if anyone cannot fulfill these tasks that they will have to formally step aside. He then goes on to say that if the rules does not deter the person that he will be waiting at the Ferris Wheel with a ring and a bouquet of lavender. He then thanks the person for their question and Sonic also thanks them but in a more dejected and sad manner: "Yeah, uh, thanks RealShadowFan01." For several of the questions answered after this one, Sonic sounds very sad.
* Shadow mentions "partner" when talking about having to follow his rules to marry him, meaning that Shadow is willing to marry anyone who can follow his rules. It can be either a man or a woman. It can even be Sonic if he wants to try.
* By how Sonic answers to the first task, you can say that he is willing to do the tasks mentioned by Shadow to get a chance to marry Shadow since Shadow said that his partner can be anyone who can follow his rules.
* Sonic's dejected voice after Shadow says he would marry the person hints at Sonic being sad that he's not the one marrying Shadow and that he wants to be the one to marry Shadow. His sad behavior afterwards also hints at this.
*Since this answer was after the question from @bryan_hedgehog, you can say that after Sonic heard that Shadow doesn't hate him that he thinks that he has a chance to be closer to him and maybe even marry him since he just heard that Shadow is willing to marry anyone who can follow his rules.
*By Shadow saying that he is willing to marry @RealShadowFan01, you can take it as Shadow saying that he is willing to marry his real fan/real number one fan. That fan can be hinted to be Sonic, especially because Sonic showed interest in following Shadow's tasks and was sad when thinking of Shadow marrying someone other than himself.

Sonic takes notice of this and glances towards Shadow. Sonic gets upset at this and pulls ahead of Shadow. Shadow then stops relaxing and goes back to driving his car normally.

In the video, they converse about how S-Fire came with the concept and went to Kazuyuki Hoshino for extra details and modifications they should make. Kazuyuki Hoshino also talks about how he thought that the fans' feedback was important. Because of this, he even went to other game creators and asked them what their favorite Sonic game was. Their answer was "Sonic Adventure 2." From this, Kazuyuki Hoshino knew that he wanted to make this figure have a big impact and be special in some way. He also talks about how he took some fan feedback to change things like Shadow's mouth placement and Shadow's inhibitor rings color.

The tornado then produces rings from the two that fly out and hit the floor before disappearing. The video also encourages others to share the animation and figure online through social media.

The video then zooms in on Sonic's Soap/Grind Shoes from Sonic Adventure 2. When zooming in on them, a description of what colors was used for it is explained by the text on screen. The video specifically focuses on Sonic's shoes being colored crimson red, enamel white and metallic silver. The phrase: "Intricately designed and painted!" is also put on the screen. When it zooms in on Shadow next, the same phrase is used and the colors used on him is also explained. The color they focused on was from Shadow's limiters, which is metallic gold. The background for the figure is then focused on. On the screen it is explained that it was inspired by the game stages in Sonic Adventure 2 by saying: "Game Stage Recreation!"

Multiple angles of the figure are shown again with another scene of Sonic and Shadow about to turn Super in Sonic Adventure 2. The video ends with showing the figure and telling the audience that it is available for pre-order.
The third video is the same as the first video, but this video is in English. Like the first video, it shows how the figure's animation would look when using the proper app.
The fourth video is the same as the second video, but it was made for their Japanese audience. Most of it is the same, but the ending when they say the figure is for pre-orders is in Japanese instead of English.

On November 11, 2023, a teaser to Sonic Prime's third season was shown by Netflix and Sonic America on YouTube. In the video it shows Sonic, Shadow and Nine in the Grim Shatterspace when Nine already put the Paradox Prism together and is using its power for his own wishes. The video begins with showing Sonic trying to convince Nine to stop what he's doing, bring back Green Hills and repair all the worlds. Nine instead gets mad at Sonic even more and says that he was only using him to get what Sonic wanted. Sonic looks down in sorrow and denies this. Nine then smiles at Sonic's reaction, calls him an old friend and that he has been replaced. Once he walks away, another type of Chaos Sonic appears in his place. Once seeing it, Sonic is amazed and questions who or what it is. Shadow then comes in and says that it's Sonic. Sonic agrees but then replies saying that if you squint and look to the side that it also looks like Shadow. Shadow looks at Sonic in disbelief, but doesn't comment on his remark. Instead, he says that whatever it is, it's in their way. Sonic then replies that it won't be for long. The Chaos Sonic then jumps from the floating platform and rams himself into Sonic and Shadow. This knocks them into the air. The video then pans to show off the new Chaos Sonic. It then shows Sonic and Shadow again landing on their feet after Chaos Sonic ran into them. Once regaining their stance, Sonic makes a comment that he already beat a Chaos Sonic in New Yolk City and asks Nine if he remembers. Nine then comments on how he was the one to save Sonic from the Chaos Sonic and that this time Sonic is on his own. Sonic makes a sad look on his face at this comment, but then Shadow comes in and says that Sonic is not on his own. Upon hearing this, Sonic looks at Shadow with relief and happiness. They then both look at the Chaos Sonic and get ready to fight it. Nine then makes a comment on his own saying that everyone is on their own. Sonic and Shadow then look at each other with a nod before they run up to the Chaos Sonic to fight him. Shadow takes the first hit by kicking Chaos Sonic that is blocked but still sends the robot flying. Sonic then tries to kick the robot too, but is dodged. The three of them then run off screen to the right. Sonic and Shadow try to get another hit in by punching and kicking Chaos Sonic, but they are dodged and grabbed by the Chaos Sonic. They are then thrown away, but the two recover quickly and try to hit the robot again. This time Shadow is successful, but it only momentarily stop the Chaos Sonic. The Chaos Sonic then runs off with Sonic and Shadow on his tail. The video then shows Nine watching it all from the floating platform. It then goes back to showing Sonic and Shadow running after the Chaos Sonic. The Chaos Sonic then abruptly turns around to face the two. Sonic takes this chance to try to get a hit on the robot, but he is dodged and slapped away. Shadow then tries to hit the Chaos Sonic with a flying kick, but if dodged again. The Chaos Sonic then runs up to the two and kicks Sonic away. Shadow then tries to fight the Chaos Sonic one on one, but is eventually kicked away. Sonic then comes in to do one on one with the Chaos Sonic. After matching some of Chaos Sonic's hits, he is able to get a successful headbutt on the Chaos Sonic, which makes him stumble backwards. Shadow then appears and takes advantage of this to give the Chaos Sonic and few kicks and passes him to Sonic who kicks him into the air. The Chaos Sonic lands a successful recovery, but just as he lands, Sonic and Shadow are ready to hit him with their spindashes. The two then hit him at the same time and slides towards the front after giving the robot a few hits. They give a few pants from the exert of energy from fighting the Chaos Sonic. The Chaos Sonic tries to get up, but Shadow jumps on top of it, which causes it to turn off. Sonic then talks to Nine saying that it's over. The video then goes to Netflix's logo and shows that the animation will come out sometime in 2024.

On July 6, 2023, to advertise the release of Sonic Prime's second season, a short video was made showing a fight between Sonic and Shadow in one of the new episodes. The video starts with showing Sonic getting up in a cloud of dust. It then cuts to show Shadow walking towards him as he says that Sonic's turn is over and that he will be taking the tech and getting the Paradox Prism shards himself. It cuts back to Sonic as he replies to Shadow saying that he won't allow it because he knows what he is capable of. He continues saying that Nine and the rest are real and that the only way he will be taking his tech is over his dead body. But before he could finish that sentence, Shadow spindashes into Sonic which makes him collide with a rock behind him. Sonic takes a deep breath and tells Shadow that he could have at least waited for him to finish what he was going to say. But just as he was about the end the sentence, Shadow tries to spindash into Sonic again. Sonic is quick to react this time and spindashes out of the way, which makes Shadow hit the rock instead. He bounces back and looks up to where Sonic left. Sonic then lands at the entrance of the cave and starts to run away. But just as he was getting to the edge of the cliff, Shadow quickly catches up and grabs Sonic, which makes them fall off the edge of the cliff. Sonic stares at him as Shadow is grabbing his arm and head. As they fall, they exchange a few blows until Sonic kicks Shadow downwards. In response, Shadow rolls up and spindashes towards the ground. Soon after landing, Sonic punches Shadow in the face, but it doesn't do much as Shadow used that opportunity to steal one of Sonic's technology with his teeth. He shows this to Sonic before using his teeth to flick the technology up and into his hand. He then tells Sonic that he has one and now he has three to go. Sonic looks at his hand in shock before getting upset and looking back at Shadow. Shadow then puts the technology on and tells Sonic that if he wants it back, he has to come get it. As he says this, he punches the ground, which causes a small shockwave of energy. Sonic then takes the challenge and they both spindash into each other. Sonic then tries to catch Shadow, and as he tries, Shadow smiles at him while dodging his attempts. Shadow then starts to dash away and Sonic follows him close behind. Shadow rams himself into Sonic and Sonic attempts to kick Shadow, but misses as they run towards the beach. At the beach, Sonic continues to chase after Shadow until Shadow gets the upper hand on him. While having the upper hand, Shadow kicks Sonic into the air and then throws him against a rock. Sonic bounces from this and it stunned in the air. Shadow then uses that opportunity to grab two technologies from Sonic's shoes. Sonic lands with a spindash and Shadow lands on his feet not too far away with the two technologies he stole on his shoes. He then counts to Sonic that he has two and now three. Sonic and Shadow then exchange a few blows with each other before Shadow pushes Sonic into the water where he gets Sonic into a position where he is gently pushing him down with one hand as he steals the last technology. Shadow then punches Sonic before swimming away, but before Shadow can get out of his reach, Sonic steals the two technologies back on Shadow's shoes. Shadow doesn't realize this as they both exit the water. He fixes his glove as he tells Sonic that now he has all the technologies and that he can enter the gateways just like him now. Just as Shadow was about to turn away, Sonic puts on the two technologies while asking him if he's sure about that. Shadow at first looks at Sonic surprised before getting upset and chasing after him. They run through Ghost Hills chasing after one another and exchanging hits until they reach a loop-de-loop. At the end of it, they grab each other and cause each other to spin in the air while trying to take each other's technologies. Shadow then kicks Sonic off of him and shows the viewer that he got the technologies from him. Shadow then lands not too far from where Sonic landed and puts on the technologies. Not noticing that Shadow has all four, Sonic taunts Shadow to try to get the last one from him. But Shadow tells him no and that he's good as he shows off that he has all the technologies. Sonic is shocked by this and reaches out towards Shadow before exclaiming, "No!" Shadow then looks at the technology on his hand and then back at Sonic as he tells him, "So long Sonic. See ya back home." Shadow then dashes off and Sonic soon follows him after again realizing that all the technologies are gone. Sonic tries to catch up to Shadow while they run up the mountain, but due to the unstable power not being regulated, Sonic is unable to control his running. This causes him to not be able to catch up. Realizing this, Shadow smiles back at Sonic and then forward as he runs fast enough to exit the Shatterspace. As Shadow exits the Shatterspace, the video cuts to show various other scenes from the season. These scenes contain shots of Sonic and the versions of his friends fighting in various places. It then cuts to show Sonic Prime's logo before announcing that the second season will be released on July 13.

Shadow at first wants to fix the universe with Sonic, but determines that he should fix the problem himself since Sonic made the mess and has shown to be too attached to the fake versions of his friends that he doesn't trust. But due to circumstances, Shadow ends up working together with Sonic after all to fix the broken universe. Because of the difference in opinions, Sonic and Shadow do fight each other in the episode. But besides fighting, Sonic and Shadow do take the time to talk to each other about what to do next to fix things on several occasions in the episode. Sonic also pushes himself to save Shadow from almost dying by saving him from falling into a void of darkness thought to decay all life.
