Warning: SPOILERS ahead for Sonic the Hedgehog 3.After the success ofSonic the Hedgehog 3, the franchise has plenty of exciting options to explore inSonic 4. Following the debut of Shadow the Hedgehog,Sonic the Hedgehog 3’s post-credits sceneshave introduced both Amy Rose and Metal Sonic to the franchise. Thanks to thisending toSonic the Hedgehog 3, there are several possibilities as to what the alreadyconfirmedSonic the Hedgehog 4will present.
After everything that happened inSonic the Hedgehog 3, there are still several more iconic characters and locations from the games that would make for welcome surprises in the future. There are also some ways thatSonic the Hedgehog 4can improve upon the source material and the films preceding it with much-needed changes to the characters. The possibilities are all but endless at this point given how much lore there is, butthere are a handful of things thatSonic the Hedgehog 4could do to make it a very special sequel.

10Stardust Speedway Appears
This Stage Is The Iconic Battleground For Sonic And Metal Sonic
Since Metal Sonic made his debut inSonic CD, one of his most notable moments in the game and the franchise as a whole was his battle against Sonic in Stardust Speedway.This neon metropolis ruled by Doctor Eggman made for an exciting battleground near the end ofSonic CD, as the blue hedgehog raced against his robot doppelganger in a fight on the highways across this colorful city.
Recreating this battle for live-action would be a terrific slice of fanservice for fans of both Sonic and Metal Sonic.

The stage also featured a killer theme song that cemented it as a classic part of Sonic’s long video game history. Recreating this battle for live-action would be a terrific slice of fanservice for fans of both Sonic and Metal Sonic. It would also make for an exhilarating fight/chase akin to Sonic and Shadow’s first fight through the streets of Tokyo inSonic the Hedgehog 3.
9More Alien Worlds From The Sonic Universe Are Introduced
It’s Time For Sonic’s Cinematic Universe To Grow Beyond Earth
After three films and one spinoff show, Sonic’s live-action adventures have been very much limited to the Big Blue Marble. Though Sonic has Rings that can instantly transport him anywhere in the universe, theSonicfilm franchise has only explored three worlds so far, including Earth. These planets are just the ones limited toSonic’s Safe Worlds Map.
Sonic 3 Officially Becomes Highest Grossing Movie In Franchise After Reaching Huge Global Milestone
Sonic the Hedgehog 3 has become the highest-grossing film in the franchise, surpassing its predecessor with an impressive global box office milestone.
Since Sonic’s cinematic universe has only just begun to unfold,the planets and realms outside of Sonic’s current home world remain a great mystery.Sonic the Hedgehog 4could shake things up by having Sonic and his pals leave Earth’s orbit to explore the other alien planets across the cosmos in their quest to save the universe. Doing so could allow the writers to introduce the other anthropomorphic characters from the Sonic games to the world of the films.

8Shadow The Hedgehog Returns
This Fan-Favorite Character Should Continue His Journey
Shadow is shown to have survived the Eclipse Cannon’s destruction at the end ofSonic the Hedgehog 3. While the film’s ending could show him branching off into his own solo adventures,it should also show Shadow returning to join the fight inSonic the Hedgehog 4.Both Shadow’s character and Keanu Reeves’s voice acting performance as the black hedgehog were huge highlightsofSonic’s third film.
Having Shadow return inSonic the Hedgehog 4would satisfy the character’s many fans. However, it would also continue the journey that only just began for him in the third movie. Since the games focused on Shadow discovering his true identity and his purpose as the protector of Earth, the nextSonicfilm should further adapt Shadow’s arc for film.

7Silver The Hedgehog Appears
This Time-Traveling Hedgehog Needs To Be Brought To The Present
Having debuted in the critically panned 2006 gameSonic the Hedgehog, the time-traveling Silver didn’t appeal to gamers at the time due to his character’s difficult gameplay and has been very much sidelined since his debut. However,Sonic the Hedgehoghas gained a cult following among fans, with Silver being a highlight of the game due to his character’s story.
Also, thanks to psychokinetic abilities,Silver is one of the few people who could rival Sonic and Shadow in combat, which could make him a formidable adversary should he make the jump to live-action. Metal Sonic’s first game,Sonic CD, did dabble in time travel.
ShouldSonic the Hedgehog 4adaptSonic CDfor the big screen, it could allow the film’s writers to faithfully introduce Silver as a warrior going back in time to prevent a dark future from occurring. While some creative liberties may have to be taken, having Silver appear inSonic the Hedgehog 4could reinvigorate the character and give him the spotlight he deserves.
6Mephiles The Dark Appears
One Of Sonic’s Darkest Villains Deserves A Spotlight
Like Silver the Hedgehog,Mephiles the Dark is a terrific but underrated characterdue to debuting in the widely hatedSonic the Hedgehoggame in 2006. Once a part of the sun deity Solaris, this demonic, time-traveling entity took the form of Shadow the Hedgehog and sought to regain his true form and destroy all of time and space. Sadistic and manipulative, Mephiles is a haunting and powerful villain with no other desire than to cause destruction simply because he can.
He also serves as the perfect foil to Shadow’s character, embodying the latter’s anger towards humanity as he tempts him with the promise of revenge. All in all, Mephiles is the Sonic franchise’s closest version of the Devil, making him a perfect villain to include in theSonicfilms, especially now that Shadow has been introduced.
5Chaos Appears
This Monstrous Deity Is One of Sonic’s Greatest Villains
Chaos is one of the most popular and powerful villains in theSonicfranchise, and he would be a compelling and fearsome adversary in the films. Introduced inSonic Adventure, this mutant Chao was once the immortal guardian of the Master Emerald, only to be consumed by evil after the Echidnas harmed his fellow Chao in their pursuit of conquest.
Harnessing the power of the Chaos Emeralds, Chaos wiped them all out and nearly destroyed the world, making him known as the"God of Destruction.“Since theChao were referenced inSonic the Hedgehog 3,the filmmakers can dig deeper intoSonicloreand bring Chaos’s storylineto theaters inSonic the Hedgehog 4.
10 Villains Who Could Replace Robotnik After Sonic The Hedgehog 3
Doctor Robotnik has been a villain in each of the Sonic the Hedgehog movies so far, and here are 10 villains who could replace him in the fourth one.
Chaos would stand out from the other villains in theSonicfilms due to his tragic backstory, silent demeanor, and primal desire for destruction. While it is unclear how Chaos could fit into a story involving Amy and Metal Sonic, the least the film could do is set up Chaos’s future appearance in a post-credits scene.
4Neo Metal Sonic Appears
Metal Sonic Should Reach His Ultimate Form
If Metal Sonic is going to be the main antagonist ofSonic the Hedgehog 4, he should, at the very least, attainthe form of Neo Metal Sonic. First appearing inSonic Heroes, this version of Metal Sonic copied the data of Sonic and his friends, including Shadow. B copying the power of Chaos, Neo Metal Sonic was even able to grow into a giant, flying mechanical dragon known as Metal Overlord.
Having Neo Metal Sonic inSonic the Hedgehog 4can help make the story faithfully adapt Sonic Heroes. Also, sinceSonic the Hedgehog 3couldn’t feature a giant kaiju like the Biolizard as the story’s final boss,Sonic the Hedgehog 4can easily make up for that byhaving Neo Metal transform into his monstrous final form against Sonic and his team.
3Tails And Knuckles Have Bigger Roles
Sonic’s Partners Need To Grow As Characters In The Next Film
Since Sonic’s third film focused more on him, Shadow, and the Robotniks, bothTails and Knuckles’s roles inSonic the Hedgehog 3were much smaller than the ones they had in the previous film. On top of that, the fourthSonicfilm seems set to focus heavily on the blue hedgehog alongside Amy and Metal Sonic. Tails and Knuckles are at risk of being sidelined once again, which is a fate unbefitting for the two of them.
Tails and Knuckles have proven themselves strong and capable characters who can carry stories and handle themselves without Sonic.
Tails and Knuckles have proven themselves strong and capable characterswho can carry stories and handle themselves without Sonic. Knuckles was even able to lead his own TV show on Max beforeSonic the Hedgehog 3. If Sonic goes off on an adventure with Amy in the next film, it would probably be best for Tails and Knuckles to do the same in order to help their friend save the world again and grow as individual characters.
2Jim Carrey Returns As Eggman Nega
Jim Carrey Can Play A Third Robotnik In Sonic’s Fourth Film
Jim Carrey has long been a highlight of theSonicfilm franchise, having played both Ivo and Gerald Robotnik throughout its three films. Though both characters seemed to have finally died inSonic the Hedgehog 3,there is a way for Carrey to returnto theSonicfranchise and continue his wickedly wacky antics. Carrey should play Eggman Nega as the villain ofSonic the Hedgehog 4.
EssentiallySonic’s version of Kang the Conqueror, Eggman Nega is Ivo Robotnik’s descendant born in the distant future, who travels back in time to destroy the world. Like Gerald, Nega is very different from Ivo, holding a grudge against the latter for besmirching the Robotnik family name.Nega Eggman’s appearance would allow Carrey to starin theSonicfranchise at least one more time. The character can exist, regardless of what has happened in the films so far.
Sonic The Hedgehog 3 Has The Most Epic Ending Of The Entire Franchise
The fight between Sonic and Shadow and Ivo Robotnik’s emotional sacrifice ensure that Sonic the Hedgehog 3 easily has the best ending of the series.
Ivo had little to zero knowledge of his family in theSonicfilms, not even knowing about Gerald or Maria’s existence untilSonic the Hedgehog 3. This ambiguity makes it possible for at least one Robotnik to still be around and continue their family’s bloodline in theSonicfilm franchise, culminating in Eggman Nega’s appearance in the distant future. He could even be the creator of theMetal Sonics seen inSonic the Hedgehog 3.
1A New Take On Amy Rose
Amy Needs To Be Improved Upon Her Video Game Counterpart
In manySonicgames,Amy Rose has been defined mainly by her unrequited love for Sonic. She has been seen constantly pursuing him around the world just to be near him, causing her to get caught up in the battles Sonic faces at the time. Though she has proven herself a righteous character and a powerful fighter with her giant hammer, Amy’s character seems more swept up in Sonic’s adventures and her romantic desires for him.
To appeal to a modern audience, Amy needs to be more than just an overzealous love interest for Sonic. She did appear to save Sonic, who seemed to have zero knowledge of her, in the post-credits scene ofSonic the Hedgehog 3. This implies that the filmmakers have already given Amy goals beyond her love for Sonic, instead having her want to fight to stop the Metal Sonics. This post-credits scene has already put Amy’s character in the right direction, which could make her a highlight inSonic the Hedgehog 4.
