Sonic's World Inhabitants

    Sonic the Hedgehog
Voiced by: Junichi Kanemaru (JP), Jason Griffith (EN)

A blue hedgehog who can run at supersonic speeds. He, his friends, and Dr. Eggman are transported to Earth by a blast of Chaos Control. Sonic, Tails, Amy Rose, Cream and Cheese live in secret with Chris Thorndyke and his family, though their presence is eventually discovered. Sonic acts as a bit of an Aloof Ally, often pulling Big Damn Heroes moments Once per Episode. Can transform into Super Sonic when he possesses the Chaos Emeralds.

  • The Ace: Leans more as this as the show progresses, especially due to his more one dimensional role and the majority of the cast's idolization of him.
  • Ace Pilot: Proved to be this when he flew the X-Tornado. Also proved to be one when he flew a government helicopter in "That's What Friends Are For."
  • Adaptational Badass: The games and other medias versions of Sonic are often powerful and competent, but still occasionally flawed and capable of being bested or forced to rely on wits. In the anime, Sonic is a blend of The Ace and The Juggernaut, unchallenged by nearly anyone. The comics tone him back down a little.
  • Aloof Ally: Downplayed case. Sonic is friendly and cheerful, but not very expressive and tends to prefer being beside himself until a threat appears. This is far less apparent in the comics. Knuckles, anyhow, was a more prominent example in earlier seasons, though not by choice.
  • Always Someone Better: A lot of characters convey an animosity towards him because of his bravado and popularity, such as Eggman, Knuckles and the Chaotix in particular have recurring jealous rivalries towards him.
  • An Odd Place to Sleep: Has a tendency to sleep on rooftops, balcony guards, the wing of the X-Tornado and even on top of a castle battlement in one instance.
  • Anti-Villain: His form, Dark Sonic, due to the fact that he's not evil, just more agressive, and pragmatic than Sonic, and only occurs when Sonic's friends get hurt.
  • Beware the Nice Ones: He's overall a pretty easy-going, and sympathetic guy, but hurting people is what sets him off. Most likely seen, when he becomes "Dark Super Sonic" in response to seeing Chris and Cosmo get hurt.
  • Big Brother Mentor: To Chris. Also while not as much as he usually is in other continuities, he has his moments with Tails.
  • Big Damn Heroes: Pulls this off Once an Episode.
    Sonic: Well, I think I've been away from Chris and the others long enough. They're bound to have gotten into trouble by now. It's time for me to make a supersonic return and save the day!
  • Breaking the Fourth Wall: The character most likely to pull this off.
  • Brilliant, but Lazy: Spends most of his time lazing around, and only sets off to defeat the Monster of the Week at the last minute.
  • Catch Phrase: In the Japanese version, he tends to exclaim "Oh shoot!" whenever something goes wrong.
  • Chick Magnet: He's shown to have many fans, including fangirls.
  • Crouching Moron, Hidden Badass: While Sonic acts foolish, and spends most of his time either goofing off or being lazy, he's pretty competent when he has to be. Most prominently shown as he is one of the few that has won a fight against Shadow.
  • Deadpan Snarker: Like in other continuities, he makes a lot of jokes at everyone, especially Knuckles.
  • Demoted to Extra: A lot more episodes are played from Chris or another heroes perspective, with Sonic acting more as something of a friendly Aloof Ally who only steps up when the Monster of the Week appears. The comics play him more as the main hero, though he later leans as a Hero Antagonist due to Eggman's expanded role.
  • Determinator: He will fight any and all threats in the galaxy, no matter how menacing or fierce they are.
  • Dissonant Serenity: He's carefree and cheerful, even in the toughest situations, knowing he'll figure things out no matter what. In fact, Dark Oak tried the Break Them by Talking method, telling him that he'll always see problems wherever he goes. Not even that stopped Sonic from keeping cool, and having a smile on his face.
  • The Empath: Has an unexplained ability to "hear" Amy and Chris when they are thinking of him.
  • The Everyman: Started as more of an Idiot Hero, but became more of this as the series progressed. The comic tones him back down to his initial wackier persona.
  • Golden Super Mode: The only animation adaptation so far to include it.
  • Gratuitous English: At least Once an Episode, at least in the Japanese dub.
  • Green Eyes
  • Healing Hands: Has the ability to heal the wounds of others whilst in his Super Form.
  • The Hero
  • Heroic Safe Mode: Almost permanently.
  • Hero with Bad Publicity: Along with his friends, he initially gets in trouble with the authorities and hides out in Chris' house when not countering Eggman's latest scheme for the early part of Season 1. A few heroic bouts later however, Sonic becomes very popular.
  • Improbable Piloting Skills: Makes you wonder why he didn't fly the planes more.
  • Invincible Hero: There's only a handful of episodes where someone beats him or even so much as effectively challenges him. Played with since Sonic does often take beatings, but he just keeps going on, his strategy and strength rarely hindered by it.
  • Jerk with a Heart of Gold: To a lesser extent. Snarky and cocky, but cares for his friends.
  • The Juggernaut: He is even more of a Lightning Bruiser than most other interpretations. If something manages to attack him, he often solves it by just amping his efforts and taking a power ring.
  • Lampshade Hanging: Displays a bit of Medium Awareness in the Japanese anime. In the comics, true to Ian Flynn's writing style, Sonic loves pointing out any story cliches and flaws that ensue.
  • Large Ham: Especially in the Japanese version. He's pretty hammy as usually.
    • In the japanese Episode 55, he screamed "I CAN'T BELIEVE IT", from the top of his lungs.
  • Lightning Bruiser: He has Super Speed, can bust through robots with ease, and can take quite a bit of damage.
  • Lovable Rogue
  • Made of Iron: He appears to be capable of taking immense physical beatings and yet get back up nearly every single time.
  • Men Don't Cry: Cries in episode 52, but his eyes are hidden from view when he does.
  • No Guy Wants to Be Chased: He doesn't like being smothered with affectionate attention, either by Amy or by his human fans.
  • One-Man Army: He takes armies of heavily armed robots, giant monsters and galactic overlords out on a regular day-basis.
  • Only Sane Man: In the episodes "Sunblock Solution" and "Eggman for President," he's initially the only person who realizes that Eggman's Egg Moon/Sunshine Ball deal is a scam and a lie because if the Egg Moon had truly stopped rotating, then it would stand still and not keep blocking the sun. When he goes about destroying the Sunshine Balls, even Sonic's pals think he's gone bad until he point-blank tells them as such.
  • Out of Focus: Even in Season 1 with Chris taking so much attention Sonic still got to be the star of most stories. By the time Season 2 arrives and introduces Shadow, Sonic gets put to the wayside even more. And once Season 3 comes about and introduces the relationship between Tails and Cosmo, it's hard to even call him The Protagonist anymore.
  • Pint-Sized Powerhouse
  • Plucky Comic Relief: For being the protagonist, he is one, mostly due to being a silly mascot, and is especially one compared to more serious characters like Knuckles, Shadow, and Knight of Cerebus Dark Oak.
  • Real Men Wear Pink: He seems to hold a strong appreciation for flowers.
  • Screw the Rules, I'm Doing What's Right
  • Sensitive Guy and Manly Man: Manly Man to Tails' Sensitive Guy, but to Knuckles or Shadow, he's the Sensitive Guy.
  • Signature Move: Spin Attack.
  • Sleepy Head: Often found sleeping on Chris' roof.
  • Super Drowning Skills: As usual, he's scared witless of water, but he's able to overcome his fear when the situation calls for it.
  • Super Speed: Naturally.
  • Superpowered Evil Side: Although it didn't make him evil, just more aggressive.
  • Vitriolic Best Buds: With Knuckles, at times. However, it's mostly in a playful manner, and they do respect each other, most of the time.
  • Walking the Earth: Although he spends a lot of his time at Chris' home, he's quite often shown traveling the world in his spare time.
  • Weaksauce Weakness: He can't swim.
  • Why Did It Have To Be Water?: Usually infallibly collected and mellow, in the face of even a puddle of water however he becomes a frantic Nervous Wreck.
  • You Gotta Have Blue Quills

    Miles "Tails" Prower
Voiced by: Ryo Hirohashi (JP), Amy Palant (EN)

An eight-year old fox with two tails, Miles "Tails" Prower is Sonic's best friend. He is a pilot, mechanic, inventor and sidekick to Sonic. While humble and sees Sonic as his idol, Tails grows to become independent and forms a Intergenerational Friendship with Chuck. He pilots the Tornado bi-plane, and then the X Tornado. Forms a romantic relationship with Cosmo in the third season.

    Knuckles the Echidna
Voiced by: Nobutoshi Canna (JP), Dan Green (EN)

Sonic's friendly rival, Knuckles is the guardian of Angel Island and the Master Emerald. Completely focused on his duty to guard the Master Emerald, Knuckles has been wandering to find it, and keeps to himself. He is short-tempered and easy on forgiveness, but he makes up for it with his courage and fists.

  • The Ace: He's a professional guardian. Its the reason why he dedicated his life to protect the Master Emerald. He also proves himself to be a great baseball player, due to his Super Strength, and is a martial artist master.
  • Adaptation Personality Change: In the games, Knuckles wasn't as gruff and hot-headed as he was here during that time, though the games gave him this characterization later on.
  • Adorkable: He tends to be shy and awkward around girls.
  • Aesop Amnesia: There have been several occasions where Knuckles has been duped by Eggman faking a Heel–Face Turn, but no matter how many times he falls for it, he'll readily fall for the same trick again. It's even lampshaded in the episode "An Enemy in Need," where Amy outright asks him just how many times he has to fall for Eggman's tricks before he learns that Eggman will never change his ways.
  • Aloof Ally: He prefers to do things alone, and tends to get pretty annoyed with Sonic's reckless ways and the group worshiping him. It was only in later episodes, that he grew more attached to the group.
  • Anti-Hero: Though nowhere near as prominent of an example as Shadow, he has trades of this.
  • Badass Armfold: He does it often with his eyes closed.
  • Badass Boast: "I'm still invincible in this competition."
  • Badass Normal: He's one of the few who is a powerful fighter without using inhabitant rings. He's able to fight on equal terms with Sonic, and is one of the most determined fighters yet.
  • Battle Couple: With Rouge.
  • Belligerent Sexual Tension: With Rouge.
  • Beware the Nice Ones: Knuckles is usually polite, but he also does have an extremely short temper, and will kick anyone's ass, for disrespecting him, or pissing him off.
  • Big Damn Heroes: His introduction in episode 1 when he saved Tails and Amy. Also when he saved Tails in episode 10.
  • Big "SHUT UP!": To Sonic in "Cracking Knuckles", for making a mockery out of him.
  • Boisterous Bruiser: He's quite a fun guy when in the right mood.
  • Butt Monkey: In season 3, he gets more prone to slapstick, and often becomes the butt of gags from the rest of the team (often owed to his solitude). This is downplayed in the comics, though he's still kinda bumbling in tone. In earlier episodes, he was rather taken seriously as a character, but still had several moments.
  • Character Development: Earlier in season 1, Knuckles was annoyed of Sonic being so reckless that he actually sent everyone to earth in a failed attempt to defeat Eggman, because now they were coming to a whole new planet they don't even know, and Knuckles doesn't know if the Master Emerald will be stolen. Because of this, Knuckles did not trust Sonic and refused to consider him a friend. In the middle of the season anyhow, Knuckles is slowly starting to accept being Sonic's friend, and though he still confronts Sonic when he acts before he thinks, Knuckles develops a genuine friendship with him in season 2 onwards.
  • Characterization Marches On: He takes some steps to the development in the process of the show. In the first 2 seasons, he was portrayed as a mysterious rouge who had his mission to accomplish, and didn't really have the time to follow the rest of the group, but grew more and more attached to them in about the middle of Season 1. In season 3, while still maintaining stoicness, is now more of a full-on team member, but doesn't seem to get the respect that he got earlier, and is a bit sillier than earlier in the show.
  • The Cassandra: Knuckles seems to have to deal with being this in most episodes.
  • Chronic Hero Syndrome: The reason why he always forgives Dr. Eggman. Knuckles's moral code is to give everyone a second chance at any time, even if it's Eggman who tricked him once too many times.
  • The Comically Serious
  • Commander Contrarian: Though he means well.
  • The Complainer Is Always Wrong: Downplayed. He tends to be the Butt Monkey due to objecting with Sonic and the others. A Running Gag is made out of the others goading or mocking Knuckles into following things through. This is never called out, even occasions he turned out to be right. However, sometimes, he's actually the voice of reason, like in Episode 10, where he explained the consequences, of playing baseball with Eggman, because of a chaos emerald. The group, however, refused to listen, and did their usual thing, which is mocking him, until he gives in. As it turned out, he was right in the end, and it would save them a lot less trouble, if they just took the emerald from Eggman, and put it to a safe place.
  • Cute Little Fangs: He has a whole set of them when he's mad or excited.
  • Deadpan Snarker: Despite how he's a very serious individual, he does have a witty sense of humor. However, he's nowhere near as snarky as Sonic, and tends to snark more in the favour of being the Only Sane Man in the group, who tends to be the only one who speaks up about Sonic's reckless ways, and then gets rejected, by the rest of the group.
  • Determinator: He's determined to protect the Master Emerald as long as he lives. He's also extremely persistent when fighting his opponents, getting up no matter how much pain he takes.
  • Depending on the Writer: Knuckles is portrayed as a one of the more serious characters in most episodes, while others make him look comedic.
  • Defeat Means Respect: He respected Emerl with a handshake and complemented him after being defeated by him.
  • The Dreaded: Eggman fights Sonic daily. However, he's terrified of Knuckles.
  • Dreadlock Rasta: This adaption gives him dreads along with his quills.
  • Dude, Where's My Respect?: He almost never gets any respect. Even after risking his life to save someone, he gets no respect at all. In fact, everyone's ungrateful attitude has actually made an impact on how Knuckles acts at times.
  • Fiery Redhead
  • Friendly Enemy: Earlier in season 1, he refused to be Sonic's friend after recklessly putting them to earth, but he still respected him. He also does respect Eggman, despite him being the Big Bad.
  • Friendly Rivalry: With Sonic, as usually.
  • The Friend Nobody Likes: Often the subject of scorn or teasing because of his poor temperament, social skills, and his tendency not to side with team planning.
  • Friendship Denial: In a couple of episodes of the first season, he loathes the idea of being Sonic's friend. This stems of the fact that the hedgehog's recklessness has led him and the others to be transported to another world, and not to mention that he gets irritated by his teasing. As time passes by, though, while he doesn't outright admit it, he has developed a firm bond with Sonic.
  • Green-Eyed Monster: Jealous of Sonic's freedom, popularity, and carefree nature, which is one of the reasons for their turbulent relationship.
  • Gullible Lemmings: Both Eggman and his own friends exploit this at times.
  • Hair-Trigger Temper: Even the slightest abrasive comment will trigger a flurry of his punches.
  • Hardcore: Knuckles is probably the most hardcore of the cast.
  • Heroes Want Redheads: Rouge has a crush on him. Despite it being unknown whether he truly likes her or not, he does have his moments where he is caring for her.
  • Horrible Judge of Character: He's constantly tricked by Eggman, and it's lampshaded every time.
  • Hot-Blooded: Knows exactly when to pick a fight with people who push his buttons.
  • Ineffectual Loner: At first he detached himself from the group, but he came around.
  • Insane Forgiveness. Knuckles believes in the good of people, therefore he will always forgive a villain no matter what bad things they do.
  • Jerkass Has a Point: Not technically a jerk, but it's hard to blame him for his temperamental attitude due to others picking on him a lot, especially by his own friends.
    • His inhospitable attitude towards Sonic may be understandable considering how reckless he can be and the fact that the hedgehog's tendency to make fun of him gets on his nerves.
  • The Lancer: A dissenting variant to Sonic.
  • Large Ham: Duh. Look who voices him.
  • Made of Iron / The Stoic: He is able to win a fight by himself after repetitively getting stomped by a giant alien with metallic body armor and being hit by thunder. He kept getting up while fighting against Yellow Zelkova in episode 72, no matter how much he had to suffer.
  • Married to the Job: Spent much of the 1st season thinking about the Master Emerald and Angel Island.
  • Megaton Punch: In episode 5, he gave one to Sonic during their fight, and then to Eggman when he realized he tricked him.
  • Misunderstood Loner With A Heartof Gold. Knuckles seems to be the most unthanked of the cast. Being mistaken for Jerkass by other the other team mates for thinking different and preferring to do things alone.
  • Mysterious Past: The Last of His Kind, that's all he knows.
  • Nobody Calls Me "Chicken"!: A Running Gag was for Sonic and co. to batter Knuckles' ego whenever he didn't want to do what they wanted to.
  • No Respect Guy: For the most part. Even Cream bullies him.
  • One-Man Army: In Episode 36, He beats a bunch of Eggman's robots who mistook him as Sonic. Even before Sonic came to help, Knuckles still defeated twice as many robots at once.
  • Only Sane Man: In Episode 10, he explains to everyone who playing baseball with Eggman is not a good idea, and they refuse to listen. Instead, they mock him into going in with the plan. Even more glaring when he turns out to be right.
  • Perpetual Frowner: Most of the time anyway, mostly due his to stoic nature. However, he's genuinely able to crack a smile, when a day is bright, and peaceful.
  • Pint-Sized Powerhouse
  • Power Fist
  • Proud Warrior Race Guy
  • Purple Eyes
  • Save the Villain: In episode 37, he saved Rouge from falling, though they were fighting. He also tried to save Yellow Zelkova from falling down to the lava after a rough fight.
  • Selfless Wish: Knuckles wishes to go back to the Master Emerald so that Angel Island won't fall into the ocean.
  • Sensitive Guy and Manly Man: The Manly Man to Sonic's Sensitive Guy.
  • The So-Called Coward: In episode 45, he was being mocked and called a coward for not wanting to enter the tournament. As it turns out, he was way braver than all of them.
  • Super Strength
  • Trademark Favorite Food: Leek buns.
  • Underestimating Badassery: He's been mocked, underestimated, and looked down by everyone. They were very wrong to do so. In japanese, Rouge admits that she was wrong to underestimate him, when he took on Shadow.
  • Vigilante Man: When he arrived on earth, Knuckles had wandered on his own to find a way back. The only thing that would take him off guard, was if someone would need help, or to be protected.
  • Vitriolic Best Buds: With a lot of the cast due to the differences of personalities, but especially with Sonic and Amy.
  • Walking the Earth: Before joining Sonic and Co., Knuckles traveled around on his own to find his way back home.
  • The Worf Effect: Being the most physically active after Sonic, he tends to be knocked down by the new threat most commonly to show their fearsomeness.
  • Would Hit a Girl: His philosophy is to not attack the weak - anyone who can stand up to him, regardless of gender, is fair game. He does, however, only hit women who are thieves.
  • Wouldn't Hurt a Child: At the tournament, he refuses to lay a hand on Chris, despite Chris wanting to fight.
  • You Wouldn't Like Me When I'm Angry: Though he's easy to cool down once it gets started, you're still going to get a beating for pushing his buttons.

    Amy Rose
Voiced by: Taeko Kawata (JP), Lisa Ortiz (EN)

Sonic's self-proclaimed love interest, Amy is an optimistic, strong-willed girl who has a long-standing crush on Sonic and wants to be his girlfriend. While she means well, she can be a bit of a handle and often glomps Sonic. In battle, she uses her trust Piko Piko Hammer. Turns deadly with her Hair-Trigger Temper.

  • Classy Cat-Burglar: She is a renowned jewel thief.
  • Combat Stilettos: Equipped with metal soles.
  • Cowboy Cop

  • Guile Heroine
  • Humanoid Female Animal: Aside from her ears, wings, and tail, she has the most human-like body proportions in the series.
  • Hypocritical Humor: She constantly mocks Knuckles, yet she expects him to treat her the same way in return. They gotten into a comical arguement about this in episode 52.
  • Impossibly-Low Neckline: Might be justified by the fact a high neckline would be inconvenient for winged characters.
  • Jerk with a Heart of Gold: She may be selfish and greedy at times, but she cares about Topaz and the others.
  • Kick Chick: She uses attacks with kicks rather than punching.
  • Light Feminine and Dark Feminine: The Dark Feminine to Amy's Light Feminine.

    Shadow the Hedgehog
Voiced by: Koji Yusa (JP), Jason Griffith (EN)

A powerful, black hedgehog who is the final result of Project Shadow, a scientific experiment headed by Eggman's grandfather Professor Gerald Robotnik. He is released by Eggman to conquer the world, though Shadow has his own motivations. Becomes an Anti-Hero in the third season.

  • Adaptational Badass: He is incredibly powerful in the video game series, but not terribly so. Here, he's even more of The Juggernaut than Sonic, with very few characters, even Sonic himself, able to slow him down for long. He also spends most of the third season as a One-Man Army against the Metarex.
  • Adaptational Villainy: While following the games' counterpart's actions far more loyally, the anime conveys Shadow as far more unfettered and cold blooded about it.
  • The Ageless: The anime never specifies his age, and all we know is he's been trapped in a capsule for 50 years and he hasn't aged at all, ever since.
  • Always Someone Better: Is this to Sonic.
  • Aloof Ally: He helps Sonic and his friends out when they need it, but he remains distant and is not an actual member of the team and sometimes ends up in conflict with them due to his extreme measures.
  • Anti-Hero: He's this after finding out Gerald Robotnik's plan onwards. In season 3, he's without a doubt heroic but he has no qualms about hitting women or weaker foes, and is probably the most violently impulsive character that isn't crazy.
  • Anti-Villain: He's on the side of justice, but he consistently gets pushed into doing villainous deeds throughout the show.
    • In the Sonic Adventure 2 adaptation, he nearly put an end to humanity because he was blinded by revenge from Maria's death until he remembered his promise to her of protecting earth.
    • When he was revived, he worked for Eggman because he was manipulated into thinking that he was a good man who wanted to help him.
    • In episode 72, he attempted to assassinate Cosmo after finding out that she betrayed Sonic and his team.
  • Artificial Hedgehog
  • Badass Armfold: Occasionally.
  • Badass and Child Duo: Was the badass to Maria's child before she died.
  • Beware the Quiet Ones: He's almost always silent and is likewise one of the most threatening characters.
  • Byronic Hero: He's always of good intentions. However, he'll often go extreme lengths to achieve what feels neccesary to him.
  • Brooding Boy, Gentle Girl: When she was alive, he was a non-romantic variant of this with Maria.
  • Big Bad: of the Shadow Saga.
  • Because You Were Nice to Me: Shows this several times in the uncut version. He thanks Rouge and continues traveling with her after she helped him out with so much. He also saved Chris and Cosmo from Black Narcissus, then told Chris that he saved him along with her to pay him back for giving him his rings.
  • Combat Pragmatist
  • Deadpan Snarker: Has his moments. Especially in japanese.
    Molly: "So, your planet is from another galaxy? What kind of place is it?"
    Shadow: "Home".
  • The Dragon: To Dr. Eggman at first.
  • Darker and Edgier: Here, he's even more edgy than in his solo game, Shadow the Hedgehog. And that says a lot.
  • Dark and Troubled Past
  • Dark Is Not Evil: He's not evil, just more extreme than the rest. His intentions are always good, despite his dark, violent ways.
  • Death Glare: Gives one to those who negotiate with him or annoy him.
  • Dragon-in-Chief: After getting revived, Shadow served Eggman and was basically used as a weapon towards his enemies. After he discovered that Eggman was only using him to get what he wants, though, Shadow decided to quit.
  • The Dreaded: Most characters fear him. Especially when he puts on the Death Glare.
  • Good Is Not Nice: The extremity of some of his efforts borders out and out villainous on occasion.
  • Friendly Rival: He does share a mutual bond and respect with Sonic, despite the occasional conflict between the two.
  • Hidden Heart of Gold: He's a rough guy around the edges. His aloof and jaded attitude makes it seem like he has no care in the world. However, Shadow is actually very helpful and caring to others.
  • Heartbroken Badass: The reason why he's such a brooding Anti-Hero, is because of his Dark and Troubled Past - seeing Maria die in front of him.
  • Heroic Sacrifice
  • Hero Antagonist: In 73 where he attempted to assassinate Cosmo after discovering that she was a spy.
  • Humans Are Bastards: His initial attitude until he remembers Maria's true wish.
  • Invincible Hero: Even moreso than Sonic.
  • Invincible Villain: He hasn't been defeated at all, and even when Sonic came close they had to save the ARK from the Biolizard.
  • Jerkass: Very cold around others and is quite violent.
  • Jerk with a Heart of Gold: He does show his soft side on a few occasions and genuinely cares about the well-being of those who have cared for him in return.
  • Jerkass Façade: He cares. But he doesn't show it because he doesn't want anyone to get too close to him out of fear of losing them like with Maria (And Molly).
  • Knight of Cerebus: Though not evil and certainly not played as straight as the Metarex, things always gets more serious whenever he appears. He was also the first character to defeat Sonic and did so with ease.
  • Ki Attacks: Chaos Spear is a mix of this and Shock and Awe.
  • Large Ham
  • Lightning Bruiser
  • Multicoloured Quills
  • Manly Tears: Cried when remembering that Maria wanted him to help the humans instead of avenging her.
  • Manly Man And Sensitive Guy: Shadow is the manly man - Brooding, mysterious and business-minded. Sonic is the sensitive guy - Cheerful, open-minded and immature.
  • Noble Demon: He's dark, cunning and unstoppable in reaching his goals, but he cares about the well-being of his companions and protects them with his life.
  • Not So Stoic: Has shown emotion at certain times.
  • Not So Invincible After All: Shadow is nearly unbeatable, but he has suffered some weaknesses. Inclusively, when Knuckles threw him into a wall, it damaged him so much that he was almost unable to get up again.
  • Older Than He Looks: He's actually 50 years old. Justified since he's immortal.
  • Psychotic Smirk: Has shown one several times.
  • Perpetual Frowner: Moreso than Knuckles.
  • Person of Mass Destruction: When he fought the Meterex Fleet alone after Molly's death and the ending of season two where he warp a blast that would destroy the universe.
  • Pint-Sized Powerhouse
  • Poor Communication Kills: "I have a reason, but I'm not going to tell you!" -Shadow, on why he is trying to attack Cosmo.
  • Red Eyes, Take Warning
  • Reformed, but Not Tamed: Returns in the Metarex saga, but aside of his memories being erased, he remains cold around others and ruthless in reaching his goals.
  • The Quiet One: He naturallly speaks with very few words and never really talks unless he has to.
  • Signature Moves: Chaos Control and Chaos Spear.
  • The Stoic: But has occasional moments where he's Not So Stoic.
  • Sugar and Ice Personality
  • Super Mode
  • Super Speed
  • Strong as They Need to Be: In some episodes, Shadow is capable of defeating Sonic effortlessly, while in others Sonic can hold him back quite well.
  • Super Strength: With his limiters off, he may be the strongest character in the show, with such feats as taking down an entire Metarex fleet with one blow. Even with them on, he's capable of overpowering Sonic fairly easily.
  • Tragic Hero: His role is a combination of the Byronic Hero, and the Woobie, Destroyer of Worlds.
  • Token Good Teammate: To Eggman when he was revived due to being tricked into thinking that he wanted to help him. When he discovers what Eggman really planned to do with him, anyhow, he stops taking orders from him and helps Sonic defeat the Metarex instead.
  • Tsundere: He comes off as arrogant, cold and aloof. But underneath it all, he is very caring and has his heart the right place.
  • Troubled, but Cute
  • Tsurime Eyes
  • Ultimate Life Form: Trope Namer, of course.
  • The Unfettered: Compared to his games counterpart, this version of Shadow is racked far less with doubt and moral conflict and will go through extreme lengths to do what he feels is right, including killing in a completely stoic tone.
  • Unscrupulous Hero: Shadow is noble and is always of good intentions. However, he'll kill in cold blood and isn't concerned about what other heroes think of it.
  • Vitriolic Best Buds: With Sonic of course.
  • Woobie, Destroyer of Worlds: Non-stop. He starts out as taking revenge against the humans for taking away the only friend he ever had, Maria. When he remembers that she wanted him to help them, and give them a chance, he finally sacrifices himself by saving the world. However, when he gets brought back to life, he's an amnesic Byronic Hero, who is heavily manipulated into extremism.
  • Weaksauce Weakness: There's only one way he can die or get unconscious, and that's if he uses too much power without using his inhabitant rings.
  • Well-Intentioned Extremist: Frequently. He's capable of killing someone in cold blood, but he always means well.
  • What the Hell, Hero?: Sonic's group had this against him when he tried to kill Cosmo. However, he had his reason, since Dark Oak is discovering them through her eyes, and ears.
  • What Happened to the Mouse?: In the third season finale, he kind of drops off the radar and isn't seen again. The end credits reveal that he somehow ended up on Molly's planet and placed a flower on her grave.
  • Wild Card: During the majority of Season 3, he switches back and fourth on sides.
  • Worthy Opponent: To Sonic.
  • Would Hit a Girl/Would Hurt a Child: He attempted to kill Cosmo, and attacked Tails in the process. Not to mention the No-Holds-Barred Beatdown he gave to Chris just for negotiating with him.

Thorndyke Residence & Family

    Chris Thorndyke
Voiced by: Sanae Kobayashi (child, JP), Masakazu Morita (adult, JP), Suzanne Goldish (child, EN), Michael Sinterniklaas (adult, EN)

A Lonely Rich Kid who serves as the main human ally to Sonic and co. when they are stranded on Earth after Dr. Eggman's botched Chaos Control. Spoiled Sweet by his often absent parents, Chris becomes quite clingy to Sonic and his friends, to the point where he suffers a breakdown of sorts when he learns that they have to return to their own world to prevent time in both worlds from coming to a halt.

In the third season, his 18-year old self researches and successfully discovers a way to travel to Sonic's world, but is transformed into his younger self upon arrival. In spite of this still maintains his older and more mature and experienced mind, and uses his accumulated knowledge to help out Sonic and his friends in new ways from the predicament they've currently find themselves in with the Metarex.

  • Adorably Precocious Child: Though he has some serious emotional hang-ups that do subvert this Trope, Chris is otherwise rather mature for his 12-year old age.
  • Audience Surrogate
  • Brainy Brunette: When he's older.
  • Character Development: Chris starts the show as a kind and mostly well-meaning kid who nonetheless has some serious emotional stunted-ness about him, caused by Parental Neglect, that leads him to making some very selfish choices at key moments. Throughout the first two seasons, we see him gradually grow and address these issues, and by Season 3, he has mostly gotten past them. There, Chris shows a resolve to pay Sonic back for the help he provided him when he was Chris's Living Emotional Crutch as a kid. In fact, Chris's role in Season 3 could be seen as a capstone that showcases and gives a finishing polish to all of his development as a character that he's had from the previous seasons. By the end of that season, he departs from Sonic and his friends in a much more mature and overall positive way than he did at the end of Season 2.
  • Designated Victim: 2/3 times someone gets captured, i.e., when it isn't Amy or Cream, it's often him. Happens less so after the Time Skip.
  • The Everyman: After Season 3's Time Skip, the young Chris becomes a version of this in the 6 years since Sonic and friend had left. Martial arts training from Mr. Tanaka and various engineering sciences from Chuck are a some of the things he picks up in that timeframe. Being able to replicate the gate and travel to Sonic's world is another.
  • Fountain of Youth: Entering Sonic's world causes his age to match the amount of time that's passed in Sonic's world rather than his own, reverting him back to his 12-year old self.
  • It's All About Me: Though he's not a chronic sufferer of this Trope, he does fall into its throes at times due to his emotional hang-ups that cause him to develop of needy disposition. He gets past this Trope altogether as time goes on, particularly after the Time Skip.
  • Japanese Pronouns: "Boku".
  • Jerkass Realization: At one point, Eggman, of all people, calls Chris out on some his more self-centered behavior, causing him to realize how much he may have hurt and wronged others because of it.
  • Living Emotional Crutch: Upon landing in his world, Sonic becomes one for Chris. It becomes very evident that this is so whenever the prospect of Sonic and friends going home comes up, as he'll suffer an emotional breakdown and become, otherwise uncharacteristically, irrational and selfish. Him running off with Sonic near the end of Season 2, despite threat of both worlds freezing in time forever, is the biggest highlight of this. When his parents show a genuine effort to patch things up with Chris, however, he's able to let Sonic go home, largely growing past this Trope. Though, Chris still remains close friends with Sonic and still feels indebted to him for all the good he's done for him, even 6 years after that point.
  • Lonely Rich Kid: Chris's mom and dad are very busy with their careers, the former's being an actress and the latter's being a jet-setting CEO. This causes him to develop some serious emotional issues, as well as a void that is originally filled by Sonic and his world spilling into Chris's.
  • Nice Guy: For the most part, Chris is a kind, sweet, and friendly kid, who isn't spoiled by the fact that his parents are rich. Over time, particularly after the Time Skip, he even develops a heroic sense of justice to him.
    • Fatal Flaw: His one hang-up is his emotional neediness, caused by his feelings with regards to the neglect of his parents, which has led to him making some very selfish decisions, at one point even getting called out by Dr. Eggman (and he would know about being selfish). He does get to a point where he admits to his selfishness, however, and grows past it by the time Season 3 roles around.
  • Only Known by Their Nickname: Rarely referred to as Christopher.
  • Parental Neglect: Suffers from the effects of this Trope to such a degree that he became emotionally needy. To feel the void of his Workaholic parents' increased absence in his life, Chris throws himself wholeheartedly into the chaos that Sonic and friends bring to his life, becoming quite attached to the blue hedgehog in the process. Upon realizing their error near the end of Season 2, Lindsey and Nelson resolve to be better parents and Chris grows past the effects of this Trope on the other side of the Time Skip.
  • Parental Substitute: Since his parents' careers keep them away from home more often than not, the day to day parental responsibilities of raising Chris are handled by his grandfather, Chuck, and his home's two attendants, Ella and Mr. Tanaka.
  • Purple Eyes: He gets it from his dad, who got it from his dad.
  • Secret Keeper: Until Sonic and co. become known to the public.
  • Shonen Hair: Looks a lot like Sora's.
  • Spoiled Sweet
  • Took a Level in Badass: He trained with Mr. Tanaka so that he could help Sonic and his friends in battle. Subverted in that his body shrinks upon going to Sonic's world, making him a lot weaker physically, though double subverted when he manages to help Sonic out in other ways.
  • Tragic Keepsake: He keeps Shadow's inhabitant ring, as the last thing Sonic found of him, from his sacrifice.
  • Unfazed Everyman: Although it was Sonic and co. who were the fish out of water on Earth, Chris was the main human to get involved, and in some ways acted like an audience surrogate. It doesn't take long for Chris to acclimate to the eccentricities that Sonic and co. brings into his life.

    Chuck Thorndyke
Voiced by: Bin Shimada (JP), Jerry Lobozzo (EN)

Chris's cool old grandpa on his father's side. He lives in the Thorndyke family mansion with his grandson, where his workshop is located. Because of his technical prowess, he and Tails often work together and quickly become friends.

  • Absurdly Youthful Father: Chuck, Nelson's father is 55 in the first part of the series while Nelson himself is 43. This means that Chuck had Nelson at only 12 years old.
  • Calling the Old Man Out: Chuck inverts this Trope by being the old man who calls the younger folks out when he admonishes his son and daughter in-law for the neglect of their son, Chris, as well as for their poor initial attempts to rectify Chris's running away because of it.
  • Cool Car: He has a vintage one.
  • Cool Old Guy
  • Gadgeteer Genius: He passes this aspect on to Chris during the Time Skip.
  • Intergenerational Friendship: With Tails.
  • Parental Substitute: To Chris, in the absence of his workaholic son and daughter in-law. Partly shares the responsibilities of raising Chris with Ella and Mr. Tanaka.
  • Purple Eyes: Passed down to son and grandson.
  • Secret Keeper: The second one in the household to learn of Sonic's existence, and helps Chris keep the secret until they become known to the public.
  • Shout-Out: To Uncle Chuck in the Sonic The Hedgehog TV show and the Archie Sonic comic book series, in that they share the same names, that they're both engineering geniuses, both closely-related to a main protagonist, and both help out Sonic and his friends.

    Mr. Tanaka 
Voiced by: Naoki Imamura (JP), Darren Dunstan (EN)

Mr. Tanaka is a very formal butler who may or may not have watched one too many martial arts movies. He helps around the Thorndyke mansion.

Ella is a pleasant but sometimes-rough-around-the-edges maid and cook who helps around the Thorndyke mansion.

    Lindsey Thorndyke 
Voiced by: Naomi Shindo (JP), Jennifer Blood (EN)

  • Beauty Mark
  • Happily Married: To Nelson.
  • Huge Guy, Tiny Girl: She's much shorter and more petite than her husband, Nelson.
  • Lethal Chef
  • Older Than She Looks: She still looks very young, even when Chris is 12 years old.
  • Parental Neglect: Not maliciously so, but like her husband, her career keeps her away from home, and so she leaves the actual parenting of her son to her father in-law, Chuck, and her house's staff, Ella and Mr. Tanaka. At the end of Season 2, when Chris runs off with Sonic for fear of being alone again, Chuck calls Lindsey and Nelson out on their neglectful behavior of raising Chris, and the two begin taking the first real steps to correct this Trope.
  • When You Coming Home, Mom?: She's too busy to spend any real time with Chris due to her acting career, more so as he grew older. When Chris runs away with Sonic at the end of Season 2, she and her husband are called out for this by Chuck, specifically after she options luring her missing son out with any toy he could want. After realizing and acknowledging this, she bursts into tears and calls herself and her husband bad parents for being so neglectful. Post-Season 3's Timeskip, it is implied that she and her husband succeeded with patching things up with Chris.
  • Workaholic: The prime reason for both hers and her husband's neglectful parenting.

    Nelson Thorndyke 
Voiced by: Ken Yamaguchi (JP), Ted Lewis (EN)

  • Happily Married: To Lindsey.
  • Huge Guy, Tiny Girl: He's much taller, and also more broad-shouldered, than his wife, Lindsey.
  • Parental Neglect: Not maliciously so, but like his wife, his career as a jet-setting CEO keeps him away from home, and so he leaves the actual parenting of his son to his father, Chuck, and his house's staff, Ella and Mr. Tanaka. At the end of Season 2, when Chris runs off with Sonic for fear of being alone again, Chuck calls Nelson and Lindsey out on their neglectful behavior of raising Chris, and the two begin taking the first real steps to correct this Trope.
  • Purple Eyes: Chris gets his eye color from his dad.
  • When You Coming Home, Dad?: Like his wife, he means well, but he doesn't get to spend any real time with Chris, especially as he grew older. Chuck finally calls him and his wife out on this problem when Chris runs away with Sonic at the end of Season 2, right before he was to return home. They do make a genuine effort to make amends, and though not outright stated, Season 3's Time Skip implies that this aspect of their relationship with their son was patched up for good after this moment.
  • Workaholic: The prime reason for both his and his wife's neglectful parenting.

    Sam Speed 
Voiced by: Souichirou Tanaka (JP), Greg Abbey (EN)

  • Big Damn Heroes: When a mob is about to attack Sonic's friends, he shows up with his entire team to chase them away.
  • Cool Uncle: Definitely is this to Chris, though Chuck is quite exasperated with him and doesn't consider him the best of influences.
  • Fiery Redhead: The guy's pretty hotblooded and energetic, and like Sonic, he's not one to stay in one place for too long.
  • I Have Many Names: In the Japanese version, he has a new nickname every episode.
  • Large Ham: Rubs his racing prowess in whenever he appears.
  • Meaningful Name: He's obsessed with speed.
  • Only Known by Their Nickname: His real name is Samuel Fair.
  • The Rival: Often aspires to challenge and surpass Sonic's speed. He never succeeds.

  • Action Girl: She is trained in the use of military combat and various firearms.
  • Boyish Short Hair: Though not as boyish as most examples.
  • By-the-Book Cop
  • Fair Cop
  • Ship Tease: Topaz seems to have romantic inclination towards Chris Thorndyke's butler, Mr. Tanaka, which seems to have started after he saved her from falling to her death when the Egg Golem dropped her.
  • Vitriolic Best Buds: With Rouge. Topaz is at first intolerant of Rouge because of her jokes at calling her old, but admired her considerable skills as a thief due to their advantages on missions. Their squabbles and jokes at the others' expense led into a playful relationship of sorts and they even began hanging out together outside work.


    Dr. Ivo "Eggman" Robotnik 
Voiced by: Chikao Ohtsuka (JP), Mike Pollock (EN)

  • Affably Evil: He wants to take over the world, he lies to get what he wants, but he respects Sonic as an enemy and often feels bad the thought of him dying. He never seems to want to kill Sonic, just defeat him, since he knows that he'd have no challenges left with no enemies to fight. He even once lectured Chris about that he needs to stop acting selfish, and it turns out his lecture helped Chris through Jerkass Realization.
  • Ambiguously Human: On top of having cartoonish proportions Eggman is also freakishly big compared to normal humans. He had to kneel down quite a bit to shake the president's hand, which also allowed the viewer to see that Eggman's fists are bigger than a normal human's head.
  • Adaptational Heroism: Subverted. He's nearly just as villainous as his game counterpart. However, his rivalry with Sonic is toned down to the point of actually being friends.
  • Anti-Villain: He is also this in the series as a whole, due to being frenemies with Sonic, and being against villains who are worse than himself, but essentially becomes one as the series goes on. Taken even further in the comic.
  • Badass Moustache
  • Badass Normal: In the comics, Eggman was able to go toe to toe with Sonic in a wrestling match.
  • Bad Boss: Treats Decoe, Bocoe, and Bokkun quite badly at times, although it's Played for Laughs and he has occasional Pet the Dog moments with them.
  • Bald of Evil
  • Beware the Silly Ones: Sometimes. In the earlier episodes at least he is feared by the humans, with a lot of his plans coming off as genuinely deadly until Sonic intervenes. He did also nearly kill Sonic at the end of the first season.
  • Big Bad: Of Season 1.
  • Breakout Character: He had a large amount of development in the anime itself. In the comics however he almost eclipses Sonic as the main star.
  • Cloud Cuckoolander
  • Determinator
  • Ditzy Genius
  • Card-Carrying Villain: He loves boasting about how evil he is.
  • Egopolis: He wants to make the world into Eggman Land, whether Sonic's world, Earth, or both!
  • Enemy Mine: Teams up with the heroes when a bigger threat comes along.
  • Even Evil Has Standards: He can threaten his hostages with no problem, but he will not hurt them.
    "It's one thing to take people prisoner and threaten them, but when you hurt somebody, that's going too far."
  • Evil Genius
  • Evil Is Hammy
  • Evil Virtues: He's very hard-working, and never gives up. He does have at least some restraints in his menace as well.
  • Evil Is Petty: He'd do anything to get on Sonic's nerves, not that he's always very successful with it.
  • Fat Bastard
  • Friendly Enemy: Has moments in the anime with Sonic, took Up to Eleven in the comics. People rarely bat an eyelash at him and his mooks appearing at a pool party.
  • Goggles Do Nothing: Never wears them.
  • Gonk: Looks more cartoony than most of the humans in the show.
  • Harmless Villain: Increasingly so as the series goes on.
  • Heel–Face Turn: Has a very brief one in the comics due to taking to his profession as popular wrestler, El Gran Gordo.
  • Ineffectual Sympathetic Villain: Depending on the Writer.
  • It's All About Me
  • Large Ham: As usual.
  • Laughably Evil
  • Mad Scientist
  • Morally Ambiguous Doctorate
  • Not-So-Harmless Villain: This childlike, not so evil, lovable goofball is the one who kidnapped Chris, caused genocide against an army, nearly killed Amy, and blew up the half of the moon!!!
  • Noblewoman's Laugh
  • The Only One Allowedto Defeat You: In the 3rd season he actually saves Sonic's life one few accessions.
  • Opaque Lenses
  • Paper-Thin Disguise: Utilizes these a fair few times in the comics, most notably with El Gran Gordo. Only Sonic tends to see through them.
  • "The Reason You Suck" Speech: Delivers an awesome one to Chris.
  • Redemption Promotion: When he's not a villain in the 3rd season, he's much more competent.
  • Robot Master
  • Sadist: Played With. He often abuses Bokkun (and is justified to be responsible for Bookun's mood swings), Decoe and Bocoe when he's bored, and has no hesitation in injuring Sonic with a smile on his face. However, he finds the idea of torture horrid and during the first season finale, when his robot went haywire in the battle with Sonic and begins to brutally beat him, Chris begs him to stop the robot and Eggman tries to stop it.
  • Stout Strength: Once beat up a bunch of crocodiles and broke a mechanical laser turret with his bare fist. In an issue of the comic he actually wrestles Sonic in hand to hand combat, and holds his ground for a while.
  • Terrible Trio: With Decoe and Bocoe.
  • Took a Level in Badass: In season 2.
  • Victory Is Boring: Becomes an Antagonist in Mourning and cries out for Sonic's attention when he doesn't return to their home planet with the rest.
  • Villain Protagonist: By the end of the comic's run, Eggman is practically the main character. Granted he held onto his "villain" role by a thread by that point. Has odd moments of this in the anime as well (he is at the very least more spotlighted than Sonic).
  • Villains Out Shopping: There are a few episodes where Eggman takes a break from trying to Take Over the World, to just stay inside of his lair, and spend time with his minions, Decoe and Bocoe, and in one episode he also cooked food to Bokkun, though he wasn't very good at it.
  • Villainous Friendship: Sort of with, Bokkun, Decoe, and Bocoe. He treats them like dirt, but he does care about them, and they seem to be the closest thing he has to friends. They're also nice to him, even after he mistreated them. Then again, his treatment of them is mostly Played for Laughs, as well as it's apart of his "evil" facade, and he actually takes care of them to an extent.
  • Worthy Opponent: Views Sonic as this (even if a lot of their bouts are somewhat one sided). His life becomes empty without Sonic around to spar with, and frequently teams up with him when another antagonist endangers them both.

    Decoe & Bocoe
Voiced by: Ken Yamaguchi (Decoe, JP), Bin Shimada (Bocoe, JP), Andrew Rannells (Decoe, EN), Darren Dunstan (Bocoe, EN)

Dr. Eggman's robotic assistants. Docoe is the tall gold one, and Bocoe is the short silver one. Though they originally start out as background characters, they eventually get more direct screentime, lines, and developed personalities. Unlike many incarnations of Eggman's minions, these two don't usually confront Sonic and Co. directly, but rather personally assist Dr. Eggman, usually in whatever base / flying fortress he's currently operating.

  • Affably Evil: They just seem to follow the orders of their creator, Dr. Eggman. Whenever they're not busy helping him, they're usually seen engaging in peaceful activities, such as daintily drinking tea. When they temporarily run away from Eggman, they live at Chris's house and prove to be very helpful and friendly.
  • Ambiguous Robots: They seem more human compared to other robots. They have humanized emotions, goofiness, and aren't waterproof.
  • Beware the Silly Ones: Unlike Dr. Eggman's lackies in previous animated shows, Docoe and Bocoe are generally competent and able to follow out their creator's orders, and show more insight than the Doctor quite a few times. For instance, they are put in charge of defending Eggman's island base when G.U.N. decides to attack it, and put up quite a fight against the navy and the air force. They are only sent packing when Dr. Eggman confronts and fails to stop a special strike force.
  • Combining Mecha
  • Deadpan Snarker: Both of them, especially towards Dr. Eggman. They make fun of everything from his weight to the ridiculousness of his plans, sometimes within earshot.
  • Expy: Personality-wise, to Scratch and Grounder. Personality-wise, to Scratch and Grounder. Appearance-wise, to Omega and Epsilon.
  • Fat and Skinny
  • Heel–Face Turn: Briefly became butlers to Chris when Eggman treated them poorly and the heroes treated them kindly. It only lasted two episodes, however.
  • Guilt-Ridden Accomplice: They sometimes feel bad for assisting Eggman in some of his more callous acts. They briefly turn sides when he kidnaps Chris after he bothered to rescue them.
  • Ineffectual Sympathetic Villains
  • Mecha-Mooks
  • Minions With An F In Evil
  • No Indoor Voice: Bocoe shouts everything in the original Japanese.
  • Red Eyes, Take Warning: Inverted. Decoe is a villain, but a rather harmless Minion with an F in Evil for the most part.
  • Sissy Villain: The two display rather effeminate and whiny habits at times, and tend to be more efficient as butlers and technical assistance for Eggman rather than any physical work.
  • Those Two Bad Guys
  • Vocal Evolution: The two bots are voiced in a stiff Robo Speak in early episodes of the English dub. Throughout the first season, while their overall pitch and synthetics remain largely the same, they gradually fluctuate into emotional human-like acting similar to their Japanese voices.

Voiced by: Yumiko Kobayashi (JP), Andrew Rannells (EN)

Eggman's childlike Messenger Robo.

  • Affably Evil: He's usually extremely cheerful, and his name-callings are rather used in a playful manner half of the time he's not angered.
  • Annoying Younger Sibling: Essentially how Docoe and Bocoe view Bokkun. For his part, Bokkun has ratted out Docoe and Bocoe to Dr. Eggman several times when they mention something unflattering towards him.
  • Bratty Half-Pint
  • Keet: Programmed with the personality of a rambunctious child.
  • Mad Bomber: Often sends explosive video messages from Eggman to the heroes.

  • Arrogant Kung Fu Girl: E-91 Lady Ninja, from what brief sentience she shows.
  • Attack of the 50-Foot Whatever: E-99 Egg Emperor.
  • Dub Name Change: E-99 Egg Emperor is changed to the Eggsterminator in the dub due to the boss of the same name from Sonic Heroes, which it looks nothing like.
  • Gratuitous Greek: Joked about "As far as their names go, it's all Greek to me".
  • The Fool: Pretty much E-77 Lucky's premise.
  • Knight of Cerebus: E-99, the fight with being one of the few moments in the series where Sonic dying is presented as possibility.
  • Lightning Bruiser: E-99, with the Chaos Emeralds powering it (we don't see it fight much without them). It moves so fast that not even Sonic can keep up with it.
  • Humongous Mecha: Some of them are big enough to qualify.
  • Minion with an F in Evil: Some of the E-Series are more loyal drones than evil, some such as Gamma and Lucky turn out to be rather benevolent when not under Eggman's control.
  • Monster of the Week: The recurring plotline of the first season was for Eggman to send in one of his robots to cause chaos each episode.
  • Spared by the Adaptation: E-100 Alpha "ZERO" is not destroyed in the anime, he is last seen comically knocked out by Amy.

    E- 102 Gamma 
Voiced by: Naoki Imamura (JP), Andrew Rannells (EN)
  • Co Dragon: Briefly acts as one alongside Chaos to Eggman, following his brothers "demotion".
  • Gender Bender / She's a Man in Japan: For unknown reasons Gamma was referred to as female in the Dutch dub, in so far that Amy solely referred to Gamma as 'Miss Robot'. The gender change may be a nod to Gamma's pink flicky (which is also referred to as Lily's sister the English dub).
  • Heel–Face Turn
  • Heroic Sacrifice
  • Minion with an F in Evil: Gamma is a robot, so most of "evil" actions owe to following Eggman's orders. As he gains emotions, he becomes increasingly empathetic and ultimately turns sides.
  • My Master, Right or Wrong: To Eggman, initially. Directly lamented in the Japanese edit.
    Sonic: You want to fight.
    Gamma: It is Eggman-sama's orders.
  • Obi-Wan Moment: Given he's a robot, it's mostly a given. However, he specifically states his happiness about Beta's bird coming out safe before shutting down in the original Japanese edit.
    E-102 Gamma: Gamma; Mission Complete...
  • Robo Speak: In both dubs, in contrast to his Machine Monotone in the games versions. Oddly, the English dub also gives him a helium pitch synthetic.
  • Robot Buddy: With Amy, even more strongly than the games story.

    Dark Oak 
Voiced by: Joji Nakata (JP), Jonathan Todd Ross (EN)

The Big Bad of Season 2, Dark Oak leads the Metarex to obtain the universe's planet eggs, hidden within the cores of every planet in existence. They were responsible for destroying Cosmo's world, actually being the male members of her species who strived to gain power but corrupted themselves in the process.

  • Knight of Cerebus: The show gets A LOT more serious when he takes over as the Big Bad.
  • Knight Templar
  • Love Redeems
  • Cosmo, I may be your father: Implied to be Cosmo's father.
  • Manipulative Bastard: We learn in "Shadow's Arrival / The Cosmo Conspiracy" that he secretly manipulated Cosmo into using Sonic and his friends to gather all of the Chaos Emeralds for him. In "The Lost Planet / Eye Spy" after that, it is revealed that Dark Oak had been using a device implanted within her head to make her his unwilling spy the whole time.
  • Orcus on His Throne: He sends Metarex out to kill Sonic, and besides that mostly just sits around and does nothing. Especially jarring given that it turns that he could have easily found and killed him whenever he wanted to.
  • Taking You with Me: After Super Sonic and Super Shadow destroy the shell of the Final Nova's planet form, he decides to try his hand at attempting to OBLITERATE the ENTIRE galaxy with himself in his final moments.
    Dark Oak: Foolish hedgehogs. With the help of the Planet Egg, you were able to stop my plans to transform the universe. But you can never win this battle... If the Metarex cannot rule the galaxy, then we will destroy it! Muahahahahahah...!
  • Tragic Villain
  • We Can Rule Together: He uses this with Sonic in the fourth-to-last episode before devouring him for deciding he would rather they get rid of him than him join the Metarex and let them take over the galaxy without a fight.
  • We Have Reserves: The Metarex seem to adopt this doctrine as a whole, and Dark Oak invokes this trope when Sonic and he meet again after their battle
    • "For each one you destroy, there are hundreds more that shall take their place".

     Yellow Zelkova 
  • A Father to His Men: Implied as the soldiers under his command seem to share his enthusiasm for victory.
  • Blood Knight: Jumps at the chance to fight the Sonic Team, demanding to face them first.
  • Boisterous Bruiser: He regularly seems jovial in his battles, my friend.
  • Card-Carrying Villain: Has stated himself to be evil a few times.
  • Disney Death: After his fight with Knuckles he falls into a volcano. Subverted in that he visibly catches on fire briefly.
  • Dumb Muscle: While undoubtedly the strongest of the 4 commanders (and possibly stronger than Dark Oak), he is as dumb as a slab of pork and just as hammy.
    • It is implied in a flashback that he used to be reasonably intelligent, though it seems to have faded over the years.
  • Faux Affably Evil: Despite his dull wit and moments of being absolutely goofy (Eggman tattoos anyone?), he gets his hands dirty more than any other commander, fighting against Sonic and nearly destroys them multiple times.
  • Front Line General: Not so much as leading his troops into battle as lead only himself into battle.
  • Large Ham: Pick ME! I shall be the representative for this TROPE!
  • Pet the Dog: He is the only one of the 3 remaining commanders (with the possible exception of Dark Oak) to miss his fellow commander Red Pine, claiming he was almost as strong as him (or in the case of the sub, was always careful).
  • The Brute: Obviously.
  • Villainous Breakdown: Suffers one as he fails to defeat Knuckles and after he knocks his armor off.

     Red Pine 
  • Continuity Nod: Is constantly referenced to after his death and is shown with the others and Dark Oak in their group picture after their people's history is revealed.
  • Forgotten Fallen Friend: Would be a villainous example if it wasn't subverted. Despite appearing once, he is mentioned in multiple episodes in passing, immediately after his death.
  • Redshirt: Quite literally.
  • Sacrificial Lamb: Appears for half of one episode and instantly dies, despite being one of the 4 commanders.
  • Small Role, Big Impact: Despite being seen in just one episode, he sets in motion the second half of the Metarex Saga and reveals the existence of the 4 commanders.

     Black Narcissus 
  • The Dragon: Shares this with Pale Bay Leaf to some extent, and they are the only commanders of the original 4 remaining when Dark Oak activates forestation.
  • Foul Flower: The only main Metarex named after a flower, and one of the most cruel.
  • Frontline General: Seen leading a campaign on an unnamed world.
  • Manipulative Bastard: Seems to be his hat and prefers to plot and scheme over diplomacy (Pale Bay Leaf) or brute force (Yellow Zelkova).
  • Narcissist: In his name.
  • The Smart Guy: Boasts his intelligence and is a natural plotter, manipulating people to do as he wants. Also knows better than to go to battle blind, wanting to gauge Sonic's abilities first before committing forces.
  • Weak, but Skilled: While he is a good plotter and capable of bending people to fall where he needs them to, he is a terrible fighter (losing to Decoe and Bocoe and Bokkun).

     Pale Bay Leaf 
  • Arm Chair Military: Unlike Yellow Zelkova (who constantly brawls with Sonic's forces), Red Pine (who goes down with his ship), and Black Narcissus (who is first seen leading a campaign planet side), Bay Leaf only fights himself at the end of the series (even his ship is seldom seen in battle, as Shadow destroys an entire fleet, but he appears later, indicating he wasn't there).
  • Genre Blind: Doesn't check to see if it was a trick after he thinks he destroyed the Blue Typhoon, gleefully going off to tell Dark Oak the good news.
  • I Lied: Played With. It is unknown if he was going to keep his promise to give the Freedom Fighters a spot in the Metarex hierarchy, but since they failed it is a moot point.
  • Inter Service Rivalry: Averted. While it looks like he and the other commanders do not do well with each other, as Pale Bay Leaf points out "we're not fighting, just having a difference of opinion".
  • Knight of Cerebus: Shared with and possibly excelled over Dark Oak. Compared to the rest of his subordinates, Pale Bay Leaf is seriously played and completely ruthless and at times darkly sadistic, particularly in his treatment of Molly's army.
  • Manipulative Bastard: More of the diplomatic type (as opposed to Black Narcissus' behind the scenes plotting).
  • The Dragon: Shares this with Black Narcissus to some extent, and they are the only commanders of the original 4 remaining when Dark Oak activates forestation.
