The success of the firstSonic The Hedgehogfilm, a movie filled featuring an abundance of wit, heart, and maniacalJim Carrey, left fans craving more. The post-credits scene scratched that itch somewhat, introducing audiences to Tails, teasing his involvement in theupcoming sequel,Sonic The Hedgehog 2.

Fans were ecstatic when the first trailer for the much-anticipated sequel dropped, revealing that Knuckles, voiced byIdris Elba, would also be making an appearance in the film. With these two fan-favorite characters confirmed to appear, and a third Sonic film already announced, now is the perfect time to consider other characters fromSonic Xand the other animated Sonic shows who could yet appear in the franchise.
Shadow The Hedgehog
Shadow The Hedgehog has been a fan-favorite character since he was first introduced to audiences in the videogameSonic Adventure 2. Shadow featured in many of the Sonic games, including headlining his own gameShadow The Hedgehog, in 2005, before being included as a central protagonist in the anime seriesSonic X.
Given that Jim Carrey’s Dr. Robotnik may be looking for some more firepower should he return to battle Sonic inthe third installment, and who better to turn to than a character equally powerful and fast as the blue blur. Moreover, Shadow’s willingness to do whatever it takes to achieve his goals, no matter who he must fight against to do so, would add an exciting, tense dynamic to any future installments.

Given the introduction of the red-haired, giant-fist-wielding Echidna Knuckles, it makes sense to think that Tikal might soon be joiningBen Schwartz’s Sonic on his next adventure. Despite appearing inSonic Adventure, Tikal is best known for her recurring role in Sonic X.

Tikal is an interesting character because, although she and Knuckles are both Echidna’s, they actually couldn’t be any more different. She is calm, respectful, and polite, whereas Knuckles is rude, aggressive, and deeply cynical. Tikal’s optimistic outlook makes her arguably a more suited guardian of the Chaos Emeralds.
Rouge The Bat
Created exclusively for the anime show Sonic X, Rouge The Bat is one of the coolest characters to ever feature in Sonic The Hedgehog media. Not only is Rogue a master thief trained in stealth, but she’s also trained in hand-to-hand combat, meaning she can go toe to toe with powerhouse Knuckles.
Rogue has endured a complicated history with Sonic and his team of friends. She initially worked alongside Shadow and Dr. Eggman before fighting against them with Sonic, although much like Shadow, Rogue is always looking out for herself. Rouge and Knuckles enjoyed a romantic connection during the series, and it would be fun for fans to see this play out on the big screen.

Manic The Hedgehog
The opening ofSonic The Hedgehogmade it clear that Longclaw raised sonic without any brothers or sisters, making this next character a little less likely to appear in a potential sequel unless his backstory was drastically changed. Manic The Hedgehog, a character fromSonic Underground, is Sonic’s brother and the drummer in the sibling’s band.

Manic is the most laid back of the family (yes, there’s somebody more laid back than Sonic), though perhaps this is because he doesn’t have any powers. This never held him back, though. Instead, he focuses on mastering his skills as a thief, making him a vital member of the team. Also, let’s be honest; we’d all love to see a hedgehog play the drums.
Silver The Hedgehog
Silver The Hedgehog has made a multitude of appearances across all forms of Sonic media over the years, proving himself to be one of thefranchise’s most powerful characters. Silver arrives in our time from two hundred years in the future, sent back to prevent the ruining of his time by resolving the many disasters and catastrophes of the past.
Silver is an incredibly powerful character, possessing psychokinesis, which is considered normal in his time, allowing him to manipulate his surroundings with just the power of his mind. Impressively, Silver manages to remain upbeat and optimistic, even though he knows that the entire world will end if he fails his mission.
Metal Sonic
This one doesn’t require much explanation. What stands a better chance of defeating the quippy speedster Sonic than a robot version of himself? Metal Sonic is a sophisticated, incredibly advanced robot built by Dr. Eggman for the sole purpose of defeating Sonic.

Not only does Metal Sonic look precisely like the blue hedgehog (it’s a decent attempt, at least), it can also imitate his moves and speed. Unfortunately for Dr. Eggman, Metal Sonic’s incredible speed actually acts against the robot. He simply cannot maintain the speeds he must reach to match Sonic, which causes his circuits to overheat, and, in some circumstances, he can even implode. Metal Sonic would be a great addition to the film franchise, especially considering how good it was to finally see Mechagodzilla on the big screen last year in Godzilla Vs Kong (which willsoon be getting a sequel).
There are countless reasons why Amy Rose should be included in an upcoming Sonic film, but none are more important than the Piko Piko Hammer that she wields. The hammer is a weapon that rivals the Chaos Emeralds in sheer awesomeness, and Amy is a fierce fighter with it in her hands.
Amy has been in love withSonicsince she was first introduced in the Sonic The Hedgehog series, and this would allow audiences to see a side of Sonic that has so far been missing from the big screen. Amy and Knuckles also have a brother/sister relationship, which could lead to the four of them (Tails included) becoming a close-knit family in the third film. At the very least, we’re hoping to see Amy and the other characters on this list included in the upcomingSonic Frontiers, thefirst open-world game in the Sonic franchise.
