It has already been confirmed that a secret character will be appearing at the end of Sonic the Hedgehog 3, and here are the 10 biggest theories for who it could be. After Tails was introduced in the post-credits scene of Sonic the Hedgehog and Shadow was introduced in the post-credits scene of Sonic the Hedgehog 2, it wasn’t a stretch to assume that the third movie would continue this trend. Luckily, there has already been confirmation that a secret character will be appearing at the end of Sonic the Hedgehog 3, and there are tons of options.

Sonic the Hedgehog director Jeff Fowler recently talked to EW about the upcoming Sonic the Hedgehog 3, and the filmmaker made some interesting comments regarding the end of the third film. Although the movie isn’t out yet, Fowler has already confirmed that Sonic the Hedgehog 3 will feature another new character in the same vein as Tails’ and Shadow’s previous reveals in the movie series. While he didn’t hint at who would be coming, this confirmation has led to all kinds of theories about who could show up in Sonic the Hedgehog 3.
“It’s fun to see the fan debates online about who’s coming up next, who’s going to be teased at the end of the film. We have a lot of the same conversations. We’ve all got our favorites on the filmmaking side, and we’re all making great cases for ‘it should be this one or that one.’ It is fun to keep that anticipation. This movie is no different in terms of teasing new characters.”

10 Metal Sonic
Dr. Eggman’s Sonic Competitor
Close
One of the most obvious choices for who could appear at the end of Sonic the Hedgehog 3 and set up a fourth movie is an iconic video game villain known as Metal Sonic. Fans of the franchise have been hoping that Metal Sonic would appear in a Sonic the Hedgehog movie since the first film, with Dr. Eggman’s robotic version of the titular blue blur being the series’ most popular villain outside of Eggman himself.

Sonic the Hedgehog 3’s first trailer makes the sequel look incredibly exciting, but it is disappointing how it ignored another Sonic project.

Now that the Sonic the Hedgehog movies have taken on Shadow’s story in Sonic the Hedgehog 3, the Metal Sonic story is the most well-known arc that the movies still haven’t covered. Metal Sonic is a popular enough character that general audiences would get excited to see him in Sonic the Hedgehog 4, and even if some audience members don’t know who he is, the premise of the character is simple enough that they could immediately get the gist in a Sonic the Hedgehog 3 post-credits scene.
9 Amy Rose
Another One Of Sonic’s Friends
Close
✕ Remove Ads
While Tails and Knuckles are Sonic’s best friends, there is still another friend that is mysteriously missing from the Sonic the Hedgehog movies: Amy Rose. Amy is the pink hammer-wielding friend of the Sonic trio, and she is the most popular Sonic the Hedgehog protagonist that hasn’t been introduced yet. Amy has appeared in all kinds of games, and adding a female protagonist to Sonic the Hedgehog 4 would be a smart move.
There have already been lots of theories that Amy Rose will appear in Sonic the Hedgehog 3, with some believing that she will appear even earlier than a post-credits scene. However, having Amy pop up in a post-credits scene would be exciting enough that it would kick off the hype cycle for Sonic the Hedgehog 4, with Amy being one of the best picks for the next live-action movie.
8 Rouge The Bat
A Theif With Connections To G.U.N.
Close
✕ Remove Ads
With the introduction of Shadow the Hedgehog in Sonic the Hedgehog 3, the live-action movie series seems to be really leaning into the Sonic Adventure storylines. Because of this, there is another obvious character who could appear at the end of Sonic the Hedgehog 3: Rouge the Bat. Rouge is a major player in the Sonic Adventure games, with her being a master thief who sometimes acts as a hero and sometimes acts as a villain.
Rouge’s connections to Shadow the Hedgehog and G.U.N. makes her a prime candidate for a Sonic the Hedgehog 3 introduction, with the movie already setting the stage for her introduction. Rouge the Bat would make a fun addition to the story of a fourth Sonic the Hedgehog movie, as while she probably wouldn’t be the main antagonist, having a wild card in the mix could make the story more dynamic.

7 Chaos
The Main Antagonist Of Sonic Adventure
Close
Shadow the Hedgehog probably won’t be the villain of Sonic the Hedgehog 4, and after already tackling Eggman storylines in the previous two movies, it is doubtful that they would make Jim Carrey’s character the main antagonist again either. If Sonic the Hedgehog 4 wants to introduce an all-new major threat to the movies, then the best choice is Chaos.
Chaos is the main villain of Sonic Adventure, with the dangerous deity having all kinds of connections to the Chaos Emeralds and the Sonic the Hedgehog franchise’s lore. Sonic the Hedgehog 3 has already teased the Chao, which are less-evolved stages of Chaos, meaning that the film could be teasing Chaos’ proper introduction. Since Chaos comes from the Sonic Adventure series, it only makes sense for the monster to appear after Sonic the Hedgehog 3‘s Sonic Adventure-heavy story.

6 Silver The Hedgehog
A Hedgehog From The Future
Close
Another popular character who could be introduced in the post-credits scene of Sonic the Hedgehog 3 is the time-traveling antagonist Silver the Hedgehog. Despite making his debut in the critically panned 2006 reboot of Sonic the Hedgehog, Silver has remained a mainstay of the franchise since his introduction, with him appearing in all kinds of spinoff video games and other Sonic the Hedgehog projects.
The easiest way to set Silver up would be to have Team Sonic do something in Sonic the Hedgehog 3 that puts the timeline in jeopardy, although they aren’t aware of it. Then, Silver can travel back in time at the end of Sonic the Hedgehog 3, with him appearing in the modern day to hunt Sonic down. This would be a fantastic story for Sonic the Hedgehog 4, relying on one of the lesser-known games for its story.

5 Blaze The Cat
An Extra Dimensional Flame Princess
Close
If Silver the Hedgehog does appear at the end of Sonic the Hedgehog 3, he probably won’t be alone, with it being likely that Blaze the Cat will appear right alongside him. In 2006’s Sonic the Hedgehog, Blaze is a futuristic royal in Silver the Hedgehog’s dark future, with her appearance being a bit mysterious. Her relationship with Silver could be expanded upon in Sonic the Hedgehog 4, clearing up these long-held fan misconceptions.
In her debut game, Sonic Rush, however, Blaze the Cat was an extra-dimensional guardian of the Sol Crystals, with her not having a connection to Silver in this story. Adapting this story would be a way for Sonic the Hedgehog 3 to introduce Blaze without needing Silver, separating the movie series from the notoriously bad Sonic the Hedgehog game.

4 Cream The Rabbit
A Hero With Connections To The Chao
With teases of the Chao in Sonic the Hedgehog 3, it only makes sense for the live-action movie series to also introduce Cream the Rabbit. Cream is a young girl who is often seen tending to the Chao, although she has gotten into the action alongside Amy and Big the Cat in Sonic Heroes. Cream would be an interesting addition to the live-action Sonic the Hedgehog movie series, with her acting as another protagonist in the ensemble cast.

While Cream the Rabbit’s introduction would be exciting and makes a lot of sense considering where the story of Sonic the Hedgehog 3 is going, it would be strange to introduce her in a post-credits scene. Cream isn’t as popular as some of the aforementioned characters, meaning that she wouldn’t get the same level of excitement as Amy or Metal Sonic. However, she is still a distinct possibility for Sonic the Hedgehog 3‘s post-credits scene.
3 E-123 Omega
Another Dangerous Eggman Invention
If Sonic the Hedgehog 3‘s post-credits scene is going to introduce a robotic creation of Dr. Eggman as its secret villain, Metal Sonic is the obvious pick. However, there is another option: E-123 Omega. E-123 Omega is one of Dr. Eggman’s most dangerous robots, with him being introduced as a playable character in the Sonic Adventure series of video games.
✕ Remove Ads
While E-123 Omega doesn’t have much of a story, he is a recognizable villain in the video game franchise, with his addition making sense if the movies want to move Eggman back to the role of main antagonist. E-123 Omega would be a fun villain for a potential Sonic the Hedgehog 4, and many fans would be excited to see his introduction.
2 Iblis
A Powerful God-Like Entity
The Sonic the Hedgehog series is surprisingly full of god-like entities that have served as the main antagonists of video games, with Iblis being another candidate for Sonic the Hedgehog 3‘s post-credits scene. Iblis is a demonic entity who acts as one of the main villains of the 2006 Sonic the Hedgehog reboot, and a character of this scale needs to be teased in a post-credits scene before making his proper debut.
✕ Remove Ads
The stage has already been set for Iblis’ introduction, and surprisingly, it was in the Knuckles spinoff show. Knuckles introduces a power known as the Flames of Disaster, something that also happens to be the nickname for Iblis. This could be a tease of Iblis’ introduction, with Knuckles now having a connection to the character.
1 Black Doom
A Villain With Connections To Shadow
Shadow the Hedgehog will presumably be a major part of the Sonic the Hedgehog movies going forward, meaning that one of the most exciting post-credits scenes would introduce Black Doom. Black Doom is another powerful entity that could serve as the villain of Sonic the Hedgehog 4, and if he is going to be introduced, it would be at the end of Sonic the Hedgehog 3.

Black Doom is an alien antagonist who also has connections to the origin of Shadow the Hedgehog, with him acting as the main villain in the Shadow the Hedgehog video game. Black Doom has become a recurring rival of Shadow and Sonic, and after his role has been expanded in the recently released Sonic X Shadow Generations, it would make sense for him to appear in Sonic the Hedgehog 3.
Sonic the Hedgehog 3 Not Yet RatedActionAdventureComedy
Sonic the Hedgehog 3 is the sequel to the 2022 comedy-adventure movie that featured the Blue Blur and his companions on an adventure to stop Dr. Robotnik from taking over the world. The new film sees the new antagonist Shadow the Hedgehog, arriving to cause trouble for the newly formed trio of heroes, Sonic, Tails, and Knuckles, as they adjust to their earthly lives.
