Sonic's World Inhabitants

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

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 note 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."
  • Adaptation Personality Change: Sonic is notably much more aloof and passive in this series. When he's not fighting Eggman, he usually spends his time sleeping where ever he can rather than hanging out with his friends or seeking out high stakes adventure.
  • Adaptation Relationship Overhaul: Compared to the games or other Sonic media, here Sonic spends significantly less time with his friends. In some episodes he even deliberately refuses to join his friends on their trips until Eggman gets involved.
  • All-Loving Hero: Much like his game incarnation, this incarnation of Sonic easily makes friends out of his former enemies and even forgives them too.
  • Aloof Ally: Downplayed case. Sonic is friendly and cheerful, but not very expressive and tends to prefer being by himself until a threat appears. He also declines the authorities' requests for his aid in fighting Eggman, as he prefers doing things on his own terms. This is far less apparent in the comics, where he's more of a do-goody hero.
  • 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. Could be considered this to Sam Speed but in a lesser extent.
  • 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 aggressive and pragmatic than Sonic. He also only occurs when Sonic's friends get hurt.
  • Beware the Nice Ones: He's overall a pretty easy-going, and sympathetic guy, but hurting his friends is what sets him off. Best 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.
  • He even lampshades this in the comic.
    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: Whenever he's not roaming the planet or being with his friends, he tends to laze around a lot, and has a few times beaten Eggman's robots at the last minute. This gets deconstructed in the Sonic Battle saga, in which people are inspired by him and start imitating his lazy and carefree lifestyle (minus the brilliant part) to their detriment.
  • Catchphrase: In the Japanese version, he tends to exclaim "Oh shoot!" whenever something goes wrong.
  • Character Exaggeration: The show takes Sonic's Super Drowning Skills and turns them into full-blown hydrophobia, to the extent that landing in a simple puddle of water in "Cracking Knuckles" triggers a panic attack until he realizes it's barely half a foot deep.
  • Chick Magnet: He's shown to have many fans, including fangirls.
  • Deadpan Snarker: Like in other continuities, he makes a lot of jokes at everyone, especially Knuckles.
  • Determinator: He will fight any and all threats in the galaxy, no matter how menacing or fierce they are.
  • Demoted to Extra: Despite the show acknowledging he's the main protagonist, 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 focus, though he later leans as a Hero Antagonist due to Eggman's expanded role.
  • 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.
  • Famed in Story: He becomes so popular to the point that his fans started a movement in his likeness and quit their jobs just to run fanclubs.
  • Golden Super Mode: As in the games, Sonic can use the seven Chaos Emeralds to achieve a Super Mode called "Super Sonic", which makes him glow, fly, and takes his already established Super Speed Up to Eleven. Sonic X is the only animated adaptation of the franchise to include it, so far.
  • Gratuitous English: Sonic would say at least one phrase in English about Once per Episode. It helps that his actor, Junichi Kanemaru, is an English teacher. So much English, so little time...
  • Healing Hands: Has the ability to heal the wounds of others whilst in his Super Form.
  • The Hero: He's the main hero of the series as per usual.
  • 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. He briefly gets this status again when he is framed for Shadow’s theft and when he starts taking down the towers for Eggman’s Sunshine Balls.
  • 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 usual.
    • 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.
  • 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.
  • Nice Guy: Similiar to his game counterpart, he is often noted for his compassion and selflessness.
  • No Guy Wants to Be Chased: He doesn't like being smothered with affectionate attention, either by Amy or by his human fans.
  • Not Helping Your Case: During the Egg Moon saga, Sonic goes about destroying Eggman's Sunshine Balls, which he's using to provide the populace with artificial sunlight after his Egg Moon supposedly malfunctioned and created a permanent eclipse, and ends up making himself a Hero with Bad Publicity in the process. While it turns out he was right to do so (Eggman was in fact deliberately controlling the Egg Moon to keep blocking the sun in order to sell the Sunshine Balls as part of a get-rich-quick scheme and to make himself a Villain with Good Publicity), he still doesn't bother telling anyone this before he starts smashing the towers, and only does so after he gets tired of fighting the combined forces of Knuckles and G.U.N., something Knuckles calls him out on; Sonic simply retorts that he thought it was obvious.
  • 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; even geniuses like Tails and Chuck forgot that detail. When Knuckles demands to know why he didn't tell them that before he went about smashing the towers, Sonic retorts that it should've been obvious.
  • Out of Focus: Even in Season 1 with Chris taking so much attention Sonic still got to be the star of all of the episodes, especially in season 2. But by the time Season 3 comes about and introduces the relationship between Tails and Cosmo, he gets pushed to the wayside a bit further.
  • Pint-Sized Powerhouse: See the One Man Army example above.
  • Real Men Wear Pink: He seems to hold a strong appreciation for flowers.
  • Screw the Rules, I'm Doing What's Right!: In the Egg Moon Saga, he goes against the Law by destroying the Mirror Towers upon (rightly) concluding that they had to be part of Eggman's latest scheme.
  • 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: Sonic X pins his top speed before bursting past the sound barrier at 600 mph, which is essentially the far limit of subsonic speeds. Later on, he races against a supersonic car and wins handily to the point a high-speed camera had to be used to show him darting past the line, coming back to make faces, and then shoot back over it again before the car catches up. Furthermore, he's shown fast enough to outrace lightning.
  • Superpowered Evil Side: Dark Super Sonic. Although it didn't make him evil, just more aggressive.
  • The Friends Who Never Hang:
    • Outside of missions, Sonic notably spends very little time with his friends from his world, usually perferring to sleep or run by himself. In some episodes (such as 5 and 9), he outright refuses offers to join his friends on their trips, only getting involved after Eggman attacks them.
    • Despite Chris' friendship with Sonic being the driving force for the former's character, the two don't spend much of their freetime together, with Chris usually hanging out with Tails, Amy, and Cream instead.
  • Übermensch: An heroic example, he doesn't care about others' rules or morals and simply fights for what he believes in. Rouge brings up this personality trait of his when the President questions why Sonic would oppose them and destroy the Mirror Towers.note 
  • 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.
    • Also has this with Shadow, due to their rivalry.
  • 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: His fear of water is much more prominent in this series. He is unable to swim, as well, and must find ways to adapt to this.
  • Why Did It Have to Be Snakes?: Sonic X takes Sonic's inability to swim and upgrades it into a personality flaw, where Sonic is literally terrified of being surrounded by or falling into large bodies of water. Even in the face of just a puddle of water he becomes a frantic Nervous Wreck.
  • You Gotta Have Blue Hair: Blue quills.

    Miles "Tails" Prower
Voiced by: Ryo Hirohashi (JP), Amy Palant (EN), Marie-Eugénie Maréchal (FR)

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.

  • Tragic Keepsake: Cosmo's seed, after he kills her. A plant on the windowsill suggests it's going to sprout into a new Cosmo.
  • Would Hit a Girl:
    • He has no problem challenging Rouge in battle. He loses. Rouge gives him points for trying, though.
    • Tails blasts Cosmo, killing her, in order to stop the plans of the villains. Doesn't mean he's happy about it.

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

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.

  • Adaptational Dumbass: While Knuckles was always Super Gullible in the games, he still eventually caught on to Eggman's tricks, and by the time of the Riders and Rivals games, refused to believe anything he said or be tricked anymore. Here, Knuckles never learns, no matter how many times it happens, that Eggman is not to be trusted in the slightest.
  • Adaptational Jerkass: The 4kids dub of episode 74 has him outright say that they should remove the device in Cosmo's head knowing full well that it would impair Cosmo's vision and hearing. In the sub version, he was against it and insisted that there had to be a way to remove it without rendering Cosmo both deaf and blind.
  • 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.
  • Aesop Amnesia: No matter how many times he's tricked by Eggman's Blatant Lies or fake Heel-Face Turns, Knuckles repeatedly fails to learn and always ends up falling for the same tricks and lies again and again. It's even lampshaded in the episode "An Enemy in Need," where Amy outright asks him just how many times he's going to fall for it before it finally sinks it for him 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 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.
  • Big Damn Heroes: His introduction in episode 1 when he saved Tails and Amy. Also when he saved Tails in episode 10.
  • The Big Guy: Despite being about the same size as Sonic, he possesses incredible strength, capable of shattering boulders many times bigger than him with his fists.
  • Big "SHUT UP!": In the episode "Cracking Knuckles", he gives Sonic one for making a mockery out of him. It gave the hedgehog pause for a moment as he realized Knuckles wasn't playing.
  • 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.
  • Cannot Tell a Joke: The reason why everyone likes to tease him. He'll always snap when a joke is aimed at him.
  • Character Development: When first introduced, Knuckles was a temperamental lone Wolf who despised Sonic for accidently sending them to earth. But he calms down and becomes more sociable during the process of the show, despite still being short tempered and abrasive. And though he still confronts Sonic when he acts before he thinks, Knuckles develops a genuine friendship with him in season 2 onwards.
  • Character Exaggeration: His Super Gullibility is taken Up to Eleven here. While Knuckles was often duped by Eggman in the games, he eventually grew wise to Eggman's tricks. X!Knuckles... never does.
  • 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 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. This is never called out and the team and even Knuckles act like the effort and fun was worth it.
    • Happens again in Cosmic Crisis, where his supposed friends steal the Master Emerald (without even apologizing or telling him about it) and then get mad at him after he gets (rightfully) angry at them.
  • Cute Little Fangs: He has a whole set of them when he's mad or excited.
  • 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 he's the Butt-Monkey of the show.
  • 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's still treated like the Butt-Monkey of the group.
  • Fiery Redhead: A red echidna who isn't afraid to use his fists.
  • 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 his extreme dislike towards him.
  • Friendly Rivalry: With Sonic, though on his part, the friendly part would be stretching it a bit.
  • 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.
  • Good Cannot Comprehend Evil: He believes in the inherit goodness of people and is always willing to give people second chances. Eggman has used this to his advantage on multiple occasions to trick him into either fighting Sonic or believing he's willing to change his ways, but Knuckles never learns.
  • Green-Eyed Monster: Jealous of Sonic's freedom, popularity, and carefree nature, which is one of the reasons for their turbulent relationship.
  • Hair-Trigger Temper: Even the slightest abrasive comment will trigger a flurry of his punches.
  • 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.
  • Jerkass Has a Point:
    • He has a massive chip on his shoulder regarding Sonic and often blames him for a lot of things, but he does have a leg to stand on since Sonic got flashy while facing Eggman and duped his robots into shooting the machine that was containing the Chaos Emeralds, which is what triggered the Chaos Control that left them stranded on Earth in the first place.
    • He gets another moment during the Egg Moon saga, again regarding Sonic. While Sonic destroying Eggman's Sunshine Balls did turn out to be the right thing to do, considering Eggman caused the eclipse that triggered their need in the first place and was keeping it up so the Egg Moon kept blocking the sun as part of a get-rich-quick scheme, Sonic didn't even bother to tell anyone this before he went about smashing the Mirror Towers, and only did so after fighting both Knuckles and the authorities when they tried to stop him. Knuckles states outright that Sonic should have just told them that before he started knocking the towers down.
  • The Lancer: A dissenting variant to Sonic.
  • 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.
  • Mysterious Past: The Last of His Kind, that's all he knows.
  • Nice Job Breaking It, Hero!: Near the end of Season 1, he ends up deciding their best chance at returning to their home world is by making a deal with Eggman and giving him the rest of the Chaos Emeralds so he can induce Chaos Control. Unsurprisingly, the minute Knuckles hands them over, Eggman double-crosses him, takes Chris hostage, and ejects Knuckles from the Egg Fort.
  • 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: He's an exceptionally skilled fighter, a cunning Trap Master on his home turf, and possess ancient knowledge not known to many. Yet, everyone treats him like an idiot due to his temper and lack of social tact. 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 that playing baseball with Eggman is not a good idea, and they refuse to listen. Instead, they mock him into going in with the plan. There's even more glaring when he actually 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: He's a short guy with a powerful punch. His knuckles have spikes on them, after all.
  • 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.
  • Sensitive Guy and Manly Man: The Manly Man to Sonic's Sensitive Guy.
  • Skilled, but Naïve: While an exceptionally skilled fighter, a cunning Trap Master on his home turf, and possessing ancient knowledge not known to many, Knuckles also lacks social tact and is Super Gullible to the point of repeatedly falling for Eggman's Blatant Lies and claims of changing his ways; while he grew up believing in honesty and the inherit goodness of people, he can't seem to comprehend that with Eggman, there's just no "good" to see.
  • Smile of Approval: In the ending of "Cracking Knuckles", after being rescued by Sonic from being blown away from the exploding machine, he looks at Sonic with a frown before smiling at him, developing respect for him.
  • Super Gullible: Eggman always manages to dupe him with his latest lie or fake Heel–Face Turn. Sonic and the others even call Knuckles out on it in "An Enemy in Need", Amy in particular:
    Amy: Knuckles, you have got to be kidding me! How many more times are you gonna fall for Eggman's tricks?!
  • Trademark Favorite Food: Leek buns.
  • Turn the Other Cheek: Knuckles believes in the good of people, therefore he will always forgive a villain no matter what bad things they do.
  • 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.
  • With Friends Like These...: His friends have a tendency to take advantage of him, jarringly noticeable (yet Played for Laughs for some reason) in Cosmic Crisis when they steal the Master Emerald and just expect him to be okay with it.
  • 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.

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

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.

  • The Ditz: She can't see the difference between Sonic and any other male hedgehog.
  • Demonic Possession: Amy gets possessed by a Boom Boo at one point in episode 19. The difference is staggering, with Scary Teeth and ghostly eyes.
  • Depending on the Writer: In some episodes she's a kind girl who is a bit short-tempered but not terribly so, while in others she's far more hot-headed. Comparing some original episodes to the adaptations, it's hard to think Amy would treat Gamma as anything more than upcoming scrap metal. In Season Three however, she's more often comic relief, so her rude and overaggressive qualities start to take over her personality more.
  • Drop the Hammer: The Piko-Piko Hammer is her weapon of choice..
  • Evil Laugh: She lets out two menacing ones out in episode 69. The English version sounds more like one.

    Cream the Rabbit & Cheese
Voiced by: Sayaka Aoki (Cream, JP), Ryo Hirohashi (Cheese, JP); Rebecca Honig (Both, EN); Marie Millet (Cream, FR), Naïke Fauveau (Cheese, FR)

A six-year old rabbit, Cream is the Tagalong Kid of the protagonists. She is very sweet and good-natured, though she misses her mother Vanilla. Cream is accompanied by Cheese, a loyal Chao who usually mirrors her feelings.

  • Adaptational Wimp: In Sonic Advance 2, Cream and Cheese were perfectly capable of racing through the same levels Sonic and co could, and actually had the easiest time defeating Eggman's machines thanks to Cheese's invincibility. Here, they're much less capable and have to be saved several times by Sonic and other characters, and are generally Non Action Guys.
  • Badass Adorable: Occasionally joins in on the fight when the plot demands it, especially during Season 3. The rest of the time she has to settle for just being adorable.
  • Badass Pacifist: Almost never fights, and doesn't like it either, but sometimes, it happens. Especially when It's Personal.
  • Berserk Button: Calling Cheese her pet - he's her friend. She also hated being questioned about her role with the team because of her age. Granted both are more "Mild Sulk Buttons" than a berserk rage, but for Cream, it's a pretty jarring showing of temper.
  • Beware the Nice Ones: Has moments where she becomes more wily or snaky, mostly Played for Laughs. Also as pacifistic as she is, Knuckles and Emerl know she is far from weak.
  • Bunnies for Cuteness: Cream is a friendly little bunny girl.
  • Cheerful Child: Despite all of the dangerous situations she finds herself in, Cream is always polite and respectful.
  • Cowardly Lion: As she's a young child, she is easily frightened. However, she does have her moments of bravery, and will get involved if she has to.
  • Damsel in Distress: Their being captured by Eggman and Sonic going to save them is the reason they got sent to Earth in the first place. An episode later, they were catptured by the human government for study, only to be rescued by Sonic and Tails. Since then, they have been avoiding this trope.
  • Deliberately Cute Child: During the baseball game, she uses her cute charms to distract Eggman's pitcher.
  • Ears as Hair: Her ears resemble Girlish Pigtails
  • Empathy Pet: Cheese usually mirrors Cream's feelings.
  • Flight: Cream can fly with her ears, but very rarely uses it. Cheese is in flight much more often.
  • Free-Range Children: Vanilla, like her games counterpart has no problem with Cream's adventures and rather nonchalantly allows her to travel with the team to fight the Meterax. This is actually lampshaded by Vector in one instance, though quickly shot down by the others.
    • Subverted at one point in the comics, when her mom was considering taking her and Cheese away from Station Square because its usually attacked by anything involving Eggman, but decided against it when they and Chris saved Vanilla and Chris's mother from ghosts.
  • Intergenerational Friendship: Most of her friends are much older than her, but this is especially prevalent in her friendship with Ella.
  • Japanese Politeness: She is polite, follows manners (and never forgets them) and does what she is told
  • Jerkass Ball: Really strangely, she can be randomly devious or snide towards Knuckles and a few others at certain times. While these instances still aren't precisely common and nearly all Rule of Funny, it's as close to having a version of Cream that isn't infallibly nice.
  • Nice Girl: She's very friendly, hardworking and tries to be close to everyone she meets, which is always returned in kind, and is always read to lend her friends a hand whenever the situation calls for it.
  • Prone to Tears: She's usually a Cheerful Child, but she's highly sensitive and prone to tears.
  • Ridiculously Cute Critter: An adorable rabbit.
  • Sailor Fuku: Her dress resembles a simplified version of one.
  • Strong Family Resemblance: Cream looks a lot like her mother outside of attire and body shape.
  • Technical Pacifist: Hates violence, but will get involved if she has to.
  • Tomboy and Girly Girl: The Girly Girl to Amy's Tomboy.
  • Took a Level in Badass: Though they rarely ever fight, being the youngest of the Sonic cast, she and Cheese are very capable of holding their own against the likes of [an out-of-control] Emerl. In the third season, they have been able to face a group of Metarex robots. Cream even flew a small space fighter near the end.

    Rouge the Bat
Voiced by: Rumi Ochiai (JP), Kathleen Delaney (EN), Marie Lenoir (FR)

A jewel thief bat who begins neutrally aligned but ends up as a government agent working for the President of the United States. She forms a friendship with her partner Topaz, and has a complicated relationship with Knuckles.

  • Adaptational Early Appearance: Appears long before the Sonic Adventure 2 arc.
  • Anti-Hero: She only does heroic work for money or emeralds in return. She worked with Topaz and GUN to avoid any previous charges of theft while she is on Earth, as well as keep a diamond she stole beforehand.
  • Bathing Beauty: She has two bath scenes, strangely with her gloves and, possibly, clothes on.
  • Beauty Is Never Tarnished: In one episode, Rouge, along with Sonic and Knuckles, need to travel through some water to get to their destination, but she objects because it would 'spoil [her] makeup'. But even after they get out of the water, Rouge's makeup is perfectly fine.
    • Defied during a tournament episodes where she and Knuckles fought in a dark tent. She left battered and bruised, but appeared fine until she lost conciousness while leaving the arena, resulting in her loss. Obviously, Knuckles did not hold back.
  • Belligerent Sexual Tension: With Knuckles. The two are rivals like in the games. However, their love interest in each other is more emphasized as the two have a few romantic conversations with each other which hinted their love in a few episodes.
  • Boobs of Steel: Has the largest breasts out of the Sonic girls due to her age and image. She literally kicks people asses with kickboxing, making her one of the stronger female characters.
  • Classy Cat-Burglar: She is a renowned jewel thief.
  • Combat Stilettos: Equipped with metal soles.
  • Cute Little Fangs: You don't see them that often, but they're there.
  • Curbstomp Battle: She gives one to Amy in the quarterfinals of the tournament and on the receiving end of one to Knuckles in the semifinals.
  • Dark Action Girl: Downplayed, as while she has worked for Eggman, she's much more of an Anti-Hero than villain.
  • Deadpan Snarker: She never holds back her sass, that's for sure.
  • Femme Fatale: Her voluptuous and daring attitude turns any man's head.
  • Flight: Being a bat, Rouge is able to fly and glide.
  • Greed: She loves gems and wishes that all the world's gems were hers.
  • 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 get into a comical argument 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, Shadow 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.
  • Loveable Rogue: She's a government agent, but she's still a thief, too. Better yet, the title works even if you misspell it!
  • Male Gaze: She tends to pose in... odd ways in the series.
  • Ms. Fanservice: She is really curvy and buxom and this animated version emphasizes much this than the video games.
  • Ms. Vice Girl: She can be heroic, but is always after jewels.
  • Sexophone: Her appearances are almost always accompanied by this.
  • Stationary Wings: Her wings rarely move when she's flying.
  • The Tease: She sarcastically flirts with Knuckles.
  • Tsundere: One moment she's teasing, insulting and beating up Knuckles and the other she starts flirting with him and making her interest on him clear.
  • Underestimating Badassery: To Tails in their battle, sure she beat him at the end but it took her more effort than she tought it would.
  • Vitriolic Best Buds: With Topaz. Though at first the regimental Topaz disapproves of the scheming Rouge (who keeps calling her an old lady), the two become friends fast.
  • Weaksauce Weakness: She can't handle loud, high-pitched noises due to her sensitive bat ears.
  • Well, Excuse Me, Princess!: In episode 52, Rogue starts criticizing Knuckles' tough guy attitude and demands him to treat her better, to Knuckles' great dismay. However, she arguably treats him the same way.
  • White Hair, Black Heart: She's not evil (not always anyway), but she's selfish and manipulative enough to qualify.
  • Wouldn't Hurt a Child: She kisses Tails to embarrass him into losing his battle with her instead of fighting him,Downplayed in that she initially tried to defeat him conventionally.

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

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 Sonic's equal and rival in all aspects in power. He is released by Eggman to conquer the world, but has his own motivation. 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 doesn't share the same way of doing things with the group which makes him detach.
  • Anti-Hero: He's this after finding out Gerald Robotnik's plan onwards. He has no qualms about hitting women or weaker foes, and is probably the most violently impulsive character that isn't crazy. But he also embeds heroic qualities, such as sacrificing himself for the greater good twice, and supporting Molly in achieving her goal to save her planet.
  • Anti-Villain: Shadow is rather confused with who to really trust. He'd much rather do good than bad, but gets pushed towards being a villain a lot during the show. When he first appeared, he was driven by the loss of his sister, Maria. Believing the humans were evil, Shadow drove a revenge scheme towards them until he was convinced of her promise to protect earth. Even there, he still saved Chris in the process despite his hatred for humanity. Much later after losing his memory, Shadow reluctantly works for Eggman, believing that he will help him get his memory back until he discovered that it was all a trick to be his pawn. After some time he traveled with Rouge, he discovered that Cosmo was a spy and attempted to assassinate her to prevent her from sending out information about Sonic and his friends, until he later joined them in fighting the Metarex.
  • Artificial Human: More like Artificial Hedgehog. He was created by Gerald Robotnik as the ultimate creature.
  • 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 the most powerful character without question. Even Sonic is unable to hold him back for long in a fight.
  • Byronic Hero: He means well. But has no calms in causing amorality to achieve what feels necessary to him.
  • Brooding Boy, Gentle Girl: When she was alive, he was a non-romantic variant of this with Maria.
  • Because You Were Nice to Me: Shows this several times in the uncut version.
    • He 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
    • He thanks Rouge and continues traveling with her after she helped him out, which seemed to surprise her.
  • Berserk Button: Do not talk about Maria in a bad way.
  • Combat Pragmatist: He isn’t afraid of fight dirty to outsmart his opponents. Demonstrated when he first fought Sonic
  • Curb-Stomp Battle: In episode 73, Shadow is able to, in one attack each, blast his way through the X-Tornado and every defense system on the blue typhoon except for the Sonic Power Cannon's barrel. Knuckles fails to stop Shadow in hand to hand combat and Tails tries to launch Shadow into space, but Shadow just Chaos Controls back.
  • Deadpan Snarker: Snarks regularly at his opponents and everyone around him.
  • The Dragon: To Dr. Eggman when he came back and suffers from amnesia, until He found out that Eggman was only using him for his personal gain.
  • Dark and Troubled Past: Motivated by the death of his only true friend, an event that scarred him for life.
  • 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 others specifically when they 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: Is often referred to as being scary by other characters. Chris (At first) and Cosmo also both seem to be frightened by him.
  • Genius Bruiser: He managed to hack into Team Sonic’s security system while beating them up one by one.
  • 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 keeps to himself but shows his compassionate side once in awhile.
  • Heartbroken Badass: Losing Maria really traumatisized him.
  • Heroic Sacrifice: He gave his life to save the world in Episode 34, and the universe in episode 78.
  • 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 does have heroic qualities.
  • The Juggernaut: Best shown when he attacks the Blue Typhoon and tries to kill Cosmo. He takes Sonic out of commission within the first few minutes, and nothing any of the others do manages to slow him down for more than a minute.
  • 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. He especially becomes this when he hunts Cosmo.
  • Ki Manipulation: Chaos Spear is a mix of this style of energy manipulation and Shock and Awe.
  • Super Speed: He’s the only one who equals this with Sonic.
  • 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.
  • Screw the Rules, I'm Doing What's Right!: Shadow is mostly of good intentions, but is not afraid to break the rules if he feels it’s neccesary. That includes stealing, lying and occasionally killing (though only when he feels someone really deserved it).
  • 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.
  • Smug Smiler: He sometimes gives a smirk smug, like the first time he fought Sonic.
  • Smug Super: As usually, He does nothing to hide his power.
  • Surrounded by Idiots: He felt this way after Sonic and his friends found out the truth about Cosmo being a spy for the Metarex, and still wanted to keep her on the team.
  • 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.
  • Tragic Hero: His role is a combination of the Byronic Hero, and the Woobie, Destroyer of Worlds.
  • The Unfettered: Much like his game counterpart, Shadow will go through extreme lengths to do what he feels is right, including killing in a completely stoic tone.
  • Unscrupulous Hero: Shadow's mortality differs from Sonic and his friends, as he is far more unfettered.
  • Vitriolic Best Buds: With Sonic of course.
  • Woobie, Destroyer of Worlds: He was originally very optimistic about visiting earth, but is only friend being shot by the GUN soldier changed his view on the world and turned him into the renegade he is now.
  • What the Hell, Hero?: Sonic's group had this against him when he tried to kill Cosmo; granted, he did have a good reason (he found out that Dark Oak was using Cosmo as an unwilling spy), but for some reason he flat-out refused to just tell everyone this.
  • 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: In Season 3, he starts off by working for Eggman until he discovered that he's been used. He then continues to travel with Rouge to defeat the Metarex. In the process, he attempts to assault Cosmo after finding out she's a Metarex spy, which resulted in fighting Sonic and all his friends. But in the end, he helps Sonic destroy the Metarex.

    Chaotix Detective Agency 
Voiced by: Kenta Miyake (Vector, JP), Yuuki Masuda (Espio, JP), Yoko Teppouzuka (Charmy, JP); Jimmy Zoppi (Vector, EN), David Wills (Espio, EN), Amy Birnbaum (Charmy, EN); Yann Le Madic (Vector, FR), Antoine Nouel (Espio, FR), Marie Millet (Charmy, FR)

  • Anti-Hero: Vector is very greedy when it comes to money, although he's generally good-natured despite that.
  • Beware My Stinger Tail: Charmy, of course.
  • Bratty Half-Pint: Charmy, to Vector's annoyance.
  • Breaking the Fourth Wall: Vector, during one episode in the third series.
    Vector: (playing a grand piano) I bet you're pretty surprised to see me playing the piano.
  • Butt-Monkey: The whole team often act as luckless comic relief.
  • Dumbass Has a Point: When Vector prepares to throw Cream into a sack to take her home to her mother whether she likes it or not, he kind of has a point. True, her mother didn't ask for Chaotix to bring her home, but it is rather insane for a six-year-old to be running around in space trying to save the galaxy from evil Metarex.
  • Face of a Thug: Vector looks rough, but he's really a self-admitted softie.
  • Flechette Storm: Espio does this with explosive shuriken.
  • Flight: Charmy, quite frequently.
  • Genius Bruiser: Vector is both the muscle and the brains behind the bunch.
  • Goggles Do Nothing: Charmy never wears his goggles.
  • Green-Eyed Monster: The Chaotix are occasionally shown to be jealous of Sonic's popularity, bravado and high lifestyle, being a much more renowned hero than them, while they struggle to make ends meet as detectives.
  • Intergenerational Friendship: Vector, Espio and Charmy are 20, 16, and 6, respectively.
  • Likes Older Women: Vector has a crush on Vanilla.
  • The Matchmaker: Vector notices Tails and Cosmo's relationship and attempts to help him woo her.
  • Mr. Vice Guy: Vector is the greediest of the trio, and convinced Espio to steal a DVD player, but he's a sweet guy.
  • Straight Man: Vector to Charmy, and Espio to Vector.
  • Vocal Evolution: In their first appearance in Episode 39, Jimmy Zoppi voices Vector in a gravelly lisped tone. In their later appearances, his rendition is completely altered into an extremely nasally bellow.

    Vanilla the Rabbit 
Voiced by: Sayaka Aoki (JP), Rebecca Honig (EN)
Creme's mother, Naïke Fauveau (FR)
  • Actual Pacifist: She doesn't engage in any fighting/violence like the heroes do.
  • Everyone Calls Her Barkeep: Goes by Mom/Mama, Cream's Mom, or Cream's Mother. No one ever refers to her by name throughout the series, or even Ms. Rabbit.
    • For some reason, there's even a sign near her house that says "The House of Cream's Mom".
  • Humanoid Female Animal: Somewhat downplayed but, like Rouge, she has something of humanoid shape, though she's heavier set and is shaped more so like a rabbit would be.
  • Team Mom: She's this to the entire non-human cast.


Thorndyke Residence & Family

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

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 16-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.

  • Brainy Brunette: When he's older and becomes a Gadgeteer Genius.
  • Character Development: Between the second and third season, he grows past his childhood brattiness and becomes a much more mature person in the six years that passed for him. During Season 3, he matures further by becoming a dependable member of Sonic's crew and by the end of that season, he departs from Sonic and his friends in a much more positive way than he did at the end of Season 2.
  • Composite Character: Amy's role in Adventure 2 of talking down to Shadow to save humanity is given to Chris, due to both him and Maria being similar to Shadow.
  • 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.
  • Expy: Aside from his Lonely Rich Kid status, Chris is pretty much a human version of Tails. Like Tails, he felt lonely growing up before he met Sonic, he believes without Sonic around he's useless, and he eventually moves past it and becomes more self-confident to the point where he does useful things even when Sonic is not there with him.
  • Fatal Flaw: He's held back by his emotional neediness, caused by his feelings with regards to the absence of his parents, which has led to him making some very selfish decisions, at one point even getting called out by Cream and Dr. Eggman of all people (and the latter would know about being selfish). He eventually gets to a point where he admits to his selfishness, and grows past it by the time Season 3 roles around.
  • Fiction 500: He's the child of a superstar actress and a wealthy businessman, and his grandfather is The Professor to boot. In one episode, he's able to provide the funds and materials that Tails needs to transform an old World War I biplane into a transforming jet fighter.
  • 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.
  • Gadgeteer Genius: Becomes this during the skip, taking over this role from Chuck in the third season.
  • Idiot Ball: He goes along with Knuckles' plan to form an alliance with Eggman to send them back to their home at the end of the first season, even after the bad doctor tells them to leave their Chaos Emeralds in his care. It ends about as well as you'd expect.
  • Impaled with Extreme Prejudice: Downplayed. In the Japanese version of episode 67, Black Narcisusus nonlethally stabs Chris in the stomach.
  • Informed Attribute: Chris was written in to the show to represent what would it be like if an average kid who represents the general child audience was best friends with Sonic the Hedgehog. However, Chris isn't exactly average as his family is wealthy and he lives with them in a mansion with his CEO father, his mother who is an actress, his grandfather who is a scientist, and he has a housemaid and a butler who lives with them with the former being a Hispanic talented cook while the latter is a Japanese bodyguard who is a skilled martial artist.
  • Informed Loner: The show says that he feels lonely because his parents spend their time at work rather than with him, which is what led to him getting so attached to Sonic. Which is undermined by the fact it's never shown how he is lonely despite being around plenty of people, in which he's living with his loving grandpa, has a second set of parents in Ella and Tanaka, regularly sees his uncle Sam, has a group of friends at public school, and all of that is before meeting Sonic and his friends. And even after that his parents do try to spend time with him when they can and feel guilty when they can't.
  • It's All About Me: Zigzagged. While he is usually a considerate kid who thinks about the well being of others, he displays an irrational and selfish behavior and a possessiveness over Sonic whenever his fears of abandonment and loneliness get the best of him when the prospect of Sonic going back to his world pops up, so much that he stopped Sonic from going back home when their worlds' timelines were going to merge and thus freezing time. When he's not under those fears, he actually does think about how homesick Sonic and his friends must feel like in Episode 25, in which he decides to help Knuckles make a truce with Eggman to help them get back home.
  • 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 act rather 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. This lessons in the final season, where he grows more emotionally stable and leans less on his friends as a result.
  • Lonely Among People: Chris is implied to be this, but the anime doesn't really expand on it enough to make it seem true, which makes Chris' Lonely Rich Kid status feel like a forced and informed conflict.
  • 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 and insecurity issues, as well as a void that is originally filled by Sonic and his world spilling into Chris'.
  • Nice Guy: Chris is usually this whenever he doesn't sink into his It's All About Me and Lonely Rich Kid statuses through the prospect of Sonic going back to his world. Even more so in the English dub where his self-centered and immature moments are downplayed to make his Spoiled Sweet traits stand out more.
  • Nice Job Breaking It, Hero!:
    • In Episode 25 he helps Knuckles with his plan to form a truce with Eggman, a plan that involves Chris stealing all of the Chaos Emeralds the heroes had previously gathered and giving them to the doctor. As one would expect, the doctor betrays them, now has all but one of the seven emeralds, and uses them to power a robot that nearly kills Sonic.
    • In Episode 32, near the end of the Sonic Adventure adaptation after Chaos already has six of the emeralds, Chris (who had found the seventh emerald) comes running up to Sonic and Knuckles holding said gem up high in his hand. Predictablly, Chaos attacks him and causes him to drop it, which allows the monster to transform into its perfect form.
    • In Episode 50, Chris closed the portal when Sonic was just about to go back to his own world, even though he knows doing so will result in time coming to a permanent stand-still. To make matters worse, it even looked like Sonic was glaring at him as if he was disappointed in Chris afterwards.
  • 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 his home's two attendants, Ella and Mr. Tanaka. His grandfather Chuck Thorndyke was also way too busy to raise Chris as he sealed himself in his lab as he was so devoted to his scientific work and research.
  • Secret Keeper: Until Sonic and co. become known to the public.
  • Shonen Hair: Looks a lot like Sora's.
  • Spoiled Sweet: Usually he's this whenever his problems regarding loneliness and his companionship is not the episode's conflict. Even more so in the English dub where his It's All About Me and bratty moments are downplayed.
  • Spotlight-Stealing Squad: He's pretty much a prime example of this. Even though he was supposed to come off as a character who represents what would it be like if an average everyday kid was friends with Sonic the Hedgehog, the anime gives him so much screen time that it even ends up overshadowing Sonic's screen time, and an Audience Surrogate doesn't usually get this much screen time, especially more than the titular character.
  • The Friends Who Never Hang: Despite Chris' friendship with Sonic being the driving force for the former's character, the two don't spend much of their freetime togehter, with Chris usually hanging out with Tails, Amy, and Cream instead.
  • 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 inhibitor 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), Antoine Nouel (FR)

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.
  • The Cameo: He makes a background appearance in the 257th issue of Archie's Sonic comic as one of the citizens evacuating Station Square during an earthquake.
  • Cool Car: He has a vintage one.
  • 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. He does most of the raising of Chris while Ella and Tanaka typically did their jobs as a house maid and butler.
  • 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), Yann Le Madic (FR)

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.

  • Battle Butler: He isn't always successful, but he certainly tries.
  • Black Bead Eyes: He has these and they make him stand out amongst the rest of the cast which has more detailed eyes.
  • Crouching Moron, Hidden Badass: Both of them to varying degrees.
  • Fat and Skinny: The Skinny to Ella's Fat.
  • Parental Substitute: Helps take on the responsibilities of raising Chris, along with Ella and Chuck, in Lindsey and Nelson's absence. But due to his responsibilities as a butler, most of the raising went to Chuck.
  • Secret Keeper: Until Sonic and co. become known to the public.
  • Shout-Out: To The Green Hornet in one episode when he and Chris dress up as him and Kato respectively.

  • Beauty Mark: A beauty mole just below her lip's left side.
  • Happily Married: To Nelson.
  • Huge Guy, Tiny Girl: She's much shorter and more petite than her husband, Nelson.
  • Lethal Chef: There's a reason why on the movie set, the chefs never let her cook a thing...
  • 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

  • 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.
  • 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), Antoine Nouel (FR)

  • Adaptation Personality Change: He has much more of a temper in the comics then in the show. Also develops some kind of a inferiority complex and jealousy towards Sonic.
  • 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.
  • Never Got to Say Goodbye: In the dub, when Sonic and co. have to return to their world, Sam shows up when they're about to walk through the portal, intending to ask Sonic for a race. He decides to leave without understanding the context, believing that he can ask later when they're done doing whatever they're doing. Averted in the original Japanese version, in which briefly showing up and leaving without saying anything was his way of saying goodbye.
  • Not So Different: Him and Sonic are both people who enjoy the high speed thrill of the their trips instead of getting to their destination. Even Amy points out how similar they are to each other.
  • 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.

  • Flat Characters: They don't really have much character outside of the Token kid tropes. Though, Helen slightly has more regarding her parents and her status as a handicapped kid, but not much to make her stand out among the human characters since she's similar to Chris.
  • Token Trio: A black kid, a tomboy, and a girl in a wheelchair.

  • 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.

Other Characters


An ancient robot created a long time ago, who is awoken by Bokkun to break Eggman out of jail, but is befriended by Cream.

Eggman Empire

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

  • Adaptational Heroism: Although he does follow the same villainous actions of his game counterpart, the anime version refuses to torture his hostages, while in the games he had no problem with torturing Sonic. This is furthered in the comics, where his Friendly Enemy status is amped more and more.
  • 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.
  • Ambiguous Situation: While he hails from Sonic's world, both Professor Gerald and his cousin Maria still hail from Earth; this leads Eggman to theorize that he was initially born on Earth and somehow ended up on Sonic's world, but it's unclear whether or not this is the case.
  • Ambiguously Human: On top of coming from another world and 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.
  • Anti-Villain: Borders on this, due to never going as far as the other villains in the series. Taken even further in the comic.
  • Badass Normal: In the comics, Eggman was able to go toe to toe with Sonic in a wrestling match.
  • Bad "Bad Acting": Vector calls him on it and Sonic recognizes it in episode 71.
  • 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.
  • 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.
  • 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.
  • Card-Carrying Villain: He loves boasting about how evil he is.
  • Did You Actually Believe...?:
    • In "A Dastardly Deed," after double-crossing Knuckles into giving him the remaining Chaos Emeralds, he makes such a speech to Chris, informing him that unlike Sonic and co., he has never cared about returning to their home planet; he just wants to establish his Eggman Empire, and either world would do.
      Chris: What do you think you're doing, Eggman?!
      Eggman: Wise up! You didn't really believe that I was homesick like your loser friends, did you? The only thing I care about is establishing the Eggman Empire. I can do that on my planet, or yours. It makes no difference to me.
    • Done again in "Eggman for President," when he reveals to Decoe and Bocoe that the Sunshine Ball/Egg Moon event was all set up by him as yet another plan, and mocks them for ever believing he had truly reformed.
      Eggman: Don't tell me you metallic meatheads think that this hero act is for real. Why, I planned this crafty little coup right from the beginning!
  • Ditzy Genius: He's capable of being threatening and was the Big Bad of Season 1 but, as we can tell, he's also not too bright
  • Egopolis: He wants to make the world into Eggman Land, whether Sonic's world, Earth, or both!
  • Dramatic Irony: Act like blurring out his monologue so Sonic crews can hear the Metarex plan to ambush them
  • 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 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.
  • Falsely Reformed Villain: During the Egg Moon saga, he claims to have changed his ways, winning good faith and publicity by rebuilding the moon, and then solving the problem of a seeming "malfunction" that caused a solar eclipse by making artificial Sunshine Balls; in reality, Eggman was deliberately controlling the Egg Moon to keep orbiting with the Earth in order to maintain the solar eclipse, and the Sunshine Balls were both a Get-Rich-Quick Scheme and a way to brainwash people into accepting him as their leader. His act is so convincing that even Decoe and Bocoe genuinely believe Eggman has actually reformed.
  • Fat Bastard: He's a villain and rotund.
  • Flaw Exploitation: He really enjoys taking advantage of Knuckles' Super Gullible nature.
  • 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.
  • 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.
  • I'm Standing Right Here: To the point of a Running Gag, Decoe, Bocoe, and occasionally Bokkun have a habit of talking smack about him or his other creations literally behind his back. For example, guess where Eggman is during this exchange:
    Bocoe: Aren't all strategies strategic?
    Decoe: Not Dr. Eggman's. His strategies lack strategy the way his tactics lack tact.
    Bokkun: And his thinking lacks thought.
  • Jerk with a Heart of Jerk: In general, whenever Eggman shows a softer side or does a "good" deed, it's nothing more than a cover-up for his own selfish purposes or Evil Plans. Best shown in the Egg Moon saga, where he rebuilds the destroyed half of the moon with robotics, and when it seemingly malfunctions and causes a permanent solar eclipse, he produces Sunshine Balls to solve the problem of a world without sunlight, winning public support and convincing everyone but Sonic he's changed for the better. As it turns out, there was no malfunction; Eggman himself was controlling the Egg Moon to keep blocking the sun so he could sell the Sunshine Balls, which doubled as Hypno Trinkets, as a Get-Rich-Quick Scheme and to brainwash the people of Earth into loving him.
  • Large Ham: It's Dr. Eggman we're talking about, of course there's going to be some scenery chewing from him.
  • Manchild: He does tend to have some childish moments in the show, but this trope is Played for Laughs.
  • 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!!!
  • Nominal Hero: In season 3, he joins forces with Team Sonic to save the world from the Metarex so he can conquer it and to prove that he can be just as much of a threat as Sonic.
  • The Only One Allowed to Defeat You: In the 3rd season he actually saves Sonic's life one few accessions.
  • Opportunistic Bastard: His first reaction upon arriving on Earth is to simply decide to conquer it if he can't conquer Sonic's world. Near the end of Season 1, after tricking Knuckles into giving him the rest of the Chaos Emeralds, he flat-out admits that he only cares about establishing the Eggman Empire; whether he does so on Sonic's world or Earth makes no difference.
  • 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 near the end of season 2 when Chris accuses him of freezing time just to get rid of Sonic.
    English version: "You're the one who's lying to yourself. You don't wanna accept the truth. Deep down, you know that once Sonic is gone, your life will have to go back to the way it was before. Your days of adventure are at an end, boy, just like your friendship with that hyper-annoying hedgehog. All your dreams have been shattered, haven't they? Life is like that, kiddo. Take it from somebody who knows! Whenever you reach too high, life smacks you down. But on the bright side, at least you and I won't have to see each other ever again."
    Japanese version: "How long are you going to act like a spoiled child, you fool?! Since you and Sonic always interfered with my plans together, I thought you were a little tougher I was wrong. You always rely on others and blame other people. If you think you can get away with that forever, you're wrong! You only want to be with Sonic? That may be enough for you. However, if that's all you care about, you'll always be small-time. Can't you understand that?!"
  • Redemption Promotion: When he's not a villain in the 3rd season, he's much more competent. And then there's his El Gran Gordo alias in the comics...
  • 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.
  • 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).
  • Villain with Good Publicity: He manages to become one during the Egg Moon saga, claiming to have changed his ways. After rebuilding half of the moon with robotics, he also solves the problem of a seeming "malfunction" that caused a solar eclipse by making artificial Sunshine Balls. In reality, Eggman is deliberately controlling the Egg Moon to keep orbiting with the Earth in order to maintain the solar eclipse, and the Sunshine Balls are also emitting a brainwashing signal to force the citizens to turn on Sonic in favor of him; once he's found out, Eggman loses his good publicity and is promptly arrested and incarcerated.
  • 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); Antoine Nouel (Decoe, Fr), Yann Le Madic (Bocoe, FR)

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.
  • 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.

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.
  • Ambiguous Robots: Supposedly a robot like Decoe and Bocoe, but has a crush on Cream, and is shown to be able to eat and drink, and generally appears more organic than his counterparts.
  • 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.
  • Keet: Programmed with the personality of a rambunctious child.
  • Mad Bomber: Often sends explosive video messages from Eggman to the heroes.
  • The Pollyanna: Bokkun is this in spades due to his rambunctious and lively attitude.
  • Stuff Blowing Up: The messages he delivers. Other characters catch onto this and get nervous when he shows up.
  • Sweet Tooth: He gets distracted by Ella's sweets.

  • 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).
  • 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.

The Metarex

    In General
Click here to see all the commanders 

The collective true antagonists of Sonic X, their most active in Season 3. A mechanical empire from another world, they are lead by Dark Oak 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 last male members of her species who strived to gain power but corrupted themselves in the process.

Tropes associated with the Metarex:

  • Aliens Are Bastards: They destroyed Cosmo's world after trying to gain power
  • Always Chaotic Evil: All the Metarex shown are antagonists, loyal to their collective cause.
  • Antagonist Title: Season 3 is otherwise known as the Metarex Saga.
  • Arc Villain: They are the collective Big Bad Duumvirate of Season 3.
  • Bishōnen Line: The Metarex come in a wide variety of different shapes and sizes, but those with higher positions of authority are a bit more humanoid and uniform than the rest, though at the same time are more decorated and visibly different from one another, as seen with their commanders.
  • Color-Coded for Your Convenience: The Metarex commanders are colored and named appropriately.
  • Cyber Cyclops: The key physical trait of every unique Metarex member are their singular large eye.
    • Eyes Do Not Belong There: The commanders have identical looking orbs on different parts of their bodies. Pale Bay Leaf is the unique standout for both tropes, having two eyes in conventional spots but also a third eye along with it and three more running down his torso, though Red Pine and Yellow Zelkova might also be subverted or at least downplayed cases of the former trope.
  • Drunk with Power: As the above states, they destroyed Cosmo's world after trying to gain power, which they got and it didn't end well.
  • Eating Machine: A few Metarex with mouths are shown actually putting their jaws to work. In Hedgehog Hunt they serve actual food and drink, though Yellow Zelkova is the only one who explicitly chows down on anything (Pale Bay Leaf is standing next to a table of food too though it's anyone guess how he eats). It's justified in Yellow Zelkova's case, as he's not actually a machine.
  • End of the World as We Know It: The Metarex extract the planet eggs from planets and leave the worlds to slowly die. Planet Cascade is a shown example of this, courtesy of Pale Bay Leaf.
  • Evil Is Bigger: Unique members are huge, with the humanoid commanders themselves already towering over the entire rest of the cast.
  • Eye Motifs: The hallmark trait of every Metarex member are their "eyes": a singular glass orb that is in most cases near pitch black and only reflects a bit of color unique to the subject. It dominates a large portion of their faces (and in some instances is their only facial feature), and the commanders even have additional identical looking orbs on different parts of their bodies; Dark Oak has one on his chest, Red Pine has two on his forehead and chest, Black Narcissus has two in his shoulders, Yellow Zelkova has two on his forehead and his "belt", and Pale Bay Leaf has five on his face running down his torso.
  • Five-Man Band: The Metarex commanders are these.
  • Gaia's Vengeance: Their true goal is to wipe out all non-plant life in the cosmos, Dark Oak's former goal as Lucas dialed Up to Eleven.
  • Galactic Conquerer: Their goal is galactic conquest, with several planets having already fallen to them before.
  • Gendercide: They were on the receiving end of this, every male Seedrian having been wiped out by Earthia and the other females of the species. However, Lucas and four others survived, going on to become the Metarex commanders and doing this back to the female Seedrians, this time with only Cosmo as the survivor. With Final Mova's destruction, all the males of their generation are completely gone, followed by the following generation's with Cosmo's death, though her sacrifice likely means this has been undone for the species.
  • Kill 'Em All: All of them are killed off by the end of Season 3, as is Cosmo, the only survivor of when they did this to their own species.
  • Knight of Cerebus: Season 3, amongst the darkest of stories in the Sonic series, is heralded by these guys as the representatives of it, and it stays that way until the very end.
  • Made of Iron: The unique Metarex moreso, but this especially applies for the commanders, where even their frailest, Black Narcissus, can still take a LOT of punishment. This even applies to them without their armor, being the only survivors of a ploy that took out every other male of their species.
  • Mecha-Mooks: They're all mechanical, but the actual Metarex Troopers are the most straight example of this.
    • Underground Monkey: Gold & Silver, two stronger Metarex Troopers painted as such and designed by Black Narcissus to test Sonic.
  • Mother Nature, Father Science: Their contrast between Cosmo's species (or what little there is of it) is fairly prominent; the feminine Seedrians are tender and gentle Plant People while the masculine Metarex are mechanical, oppressive Space Pirates.
  • No Mouth: It's 50/50 whether a Metarex unit has a visible, conventional jaw or not, which applies for the commanders as well; Dark Oak and Red Pine have no semblances of one, Black Narcissus and Pale Bay Leaf have vague semblances of mouths, and Yellow Zelkova has a large, blocky mouth guard with grills, him being the only one of the five to be shown actually eating anything.
  • Non-Standard Character Design: Compared to the cartoony Mobians and Eggman or the fairly grounded humans and machines (if not at least sometimes elaborate), the Metarex all look like they came from an entirely different anime with their detailed and uniform designs, particularly the commanders. It does work to good effect, given they are the antagonistic alien force of Season 3, thusly allowing them to stand out strikingly with how jarringly threatening looking they can be.
  • Off-Model: A particularly egregious example; though Sonic X isn't particularly known for stellar animation, the Metarex commanders usually have a few parts of their bodies colored incorrectly between scenes, sometimes missing a few of their less noticeable physical traits.
  • One-Gender Race: Though they're machines, they have obviously masculine voices and the commanders are referred to with male pronouns. It's played with in a roundabout way, as the Metarex commanders are male Seedrians, the only survivors out of hundreds that survived a cataclysmic explosion that struck them during their war against an unknown opponent years ago. After they fought back, Cosmo would be left as the last living female of her species.
  • Theme Naming: Twofold for the commanders.
    • Colorful Theme Naming: Their names start with the color their bodies are primarily painted, even with the less obvious examples: Dark-, Red-, Yellow, Black- and Pale-.
    • Floral Theme Naming: Oddly for their mechanical visages, the second halves of their names are various plantlife: -Oak, -Pine, -Zelkova, -Narcissus and -Bay Leaf. This turns out to be a big hint at their true identities.
  • Unrobotic Reveal: A big twist is that Cosmo is not really the last of her species, but rather the last female of her species; the Metarex commanders are revealed to be the last male Seedrians, though only Dark Oak & Yellow Zelkova's true forms are shown off and only the former's original name is revealed (Lucas).
  • Voice of the Legion: All Metarex members that talk have noticeable robotic filters over their voices.
    • Power Echoes: In the sub, in place of the filter the Metarex have a very apparent reverb to their voices.

    Dark Oak
"Oh, perfect: One day they will learn the true extent of my power, but by then they will be too late!"
Voiced by: Joji Nakata (JP), Matt Hoverman (EN), Antoine Nouel (FR)

The Greater-Scope Villain of Season 2 and Big Bad of Season 3. Dark Oak is the leader of the Metarex, having co-founded it alongside his fellow commanders.

Tropes associated with Dark Oak:

  • Authority Equals Ass Kicking: This guy BEAT Super Sonic (likely very badly considering he only had some slight superficial damage while Sonic was exhausted), who was presented as invincible in the first two seasons.
  • Big Bad: Of Season 3, as the head of the Metarex.
  • The Chessmaster: His smooth plans involved using Cosmo as a spy to have all seven Chaos Emeralds gathered for him so he could bring them together for the Forestation process.
  • Combat Tentacles: Beneath his large shoulders are massive, segmented tendrils.
  • Cyber Cyclops: He has a single, bright green eye on his head, notably shown with more color than usual compared to his fellow commanders. Subverted in that he actually has two eyes.
  • Darth Vader Clone: Fits this in every way. Dark and Troubled Past, Badass Cape, Cool Helmet, Noble Demon, We Can Rule Together etc. Plus, his desire to destroy planets, and formerly being a hero, to doing a Heel–Face Turn after in the very end.
  • Did You Just Punch Out Cthulhu?: The first thing he does on screen is beat Super Sonic in a fight, if not outlast. He remains the only villain in any Sonic series to actually defeat Super Sonic in a fair fight.
  • Death Equals Redemption: Upon his defeat, he finally realizes that he was wrong in his goals and that his wife was right all along, ultimately passing into the afterlife with her.
  • Even Evil Has Loved Ones: He did love his wife Earthia, even when he started going to darker methods to win the planetary war, but the relationship turned strained when she turned against him and they both claimed the other was a traitor. Then it was obliterated when she nuked the planet with him and his followers still on it to wipe out most of the males of their race and he eventually retaliated by destroying her and her follower's ship to wipe out most of the females. By the very end, however, he seems to rekindle that love when he admits she was right all along.
  • Everything's Better with Samurai: He's evidently modeled after a shogun of sorts (most prominently, his head), what with being the leader of the Metarex and wielding swords.
  • Evil Sounds Deep: He always has a pretty deep baritone, regardless of which dub.
  • For the Evulz: What his motivation as leader of the Metarex amounts to at first, until his true origins are revealed.
  • He-Man Woman Hater: He didn't start out that way but he shows shades of this after his wife, Earthia, turned against him for his ways.
  • Horned Humanoid: Double Subverted. His head isn't really horned like his comrades' and more akin to a kabuto with a crest on it. As a Seedrian, however, he did have blunt, brown horns.
  • Knight of Cerebus: The show gets A LOT more serious when he takes over as the Big Bad.
  • Knight Templar: As the war that ravaged his planet continued, he eventually became convinced that life as the universe knew it was too flawed and he needed to reset it in order to end all wars and conflict, regardless of how many would have to die to see it through.
  • Luke, I Might Be Your Father: Implied to be Cosmo's father.
  • Machine Monotone: Played with. His voice filter is the heaviest of all the Metarex to the point it makes him actually sound like a more genuine robot, which only furthers how he does have a tendency to Chew the Scenery.
  • 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.
  • Mister Big: He's actually the shortest of the Metarex commanders by a considerable amount. It's downplayed, as 6'6 is still very tall, and exemplifies moreso how he and especially his peers are huge compared to the heroes or even Eggman.
  • 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.
  • Purple Is Powerful: Predominantly colored purple, and is both the leader of the Metarex and the most powerful of all the antagonists in Sonic X.
  • 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 have indeed prevented me from transforming the galaxy. But you can never win this battle. If the Metarex cannot rule the galaxy, then we will destroy it! Muahahahahahah...!
  • Together in Death: In the end, he was reunited with his beloved wife in his final moments before joining her in the afterlife.
  • Tragic Villain: At one point, he was a warrior desperate to win a great war for his planet by any means necessary, even if it risked the very life of his planet in the process. As a result, he lost his people, his wife's love and respect, his planet, and his morality as he refashioned himself into a galactic conqueror and murdered the majority of his surviving species' females for betraying him and turned what might have been his only remaining daughter into an Unwitting Pawn for his schemes.
  • Unrobotic Reveal: In "The Lost Planet / Eye Spy", just like Yellow Zelkova, he is revealed to be of the same species as Cosmo, and potentially even her father.
  • Viler New Villain: To Dr. Eggman. As bad as Eggman could get, he wasn't a sadist, was Affably Evil, and wanted to conquer the world, not destroy it. Dark Oak is a genocidal monster who's destroyed multiple planets by stealing their Planet Eggs, plotted to wipe out all non-plant life forms in the galaxy, and decides to destroy the entire galaxy in his final moments rather than let Sonic and Shadow win.
  • 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.
  • You Gotta Have Blue Hair: His hair is revealed to be deep purple, a bit more unusual than Cosmo & Yellow Zelkova's green shades.

     Yellow Zelkova
"This task requires strength: It is I who should go; Yellow Zelkova!"
Voiced by: Takeshi Watabe (JP), Ted Lewis (EN), Benoit DuPac (FR)

The very obvious muscle of the Metarex commanders, Yellow Zelkova is a classical Boisterous Bruiser to his core, a chummy fellow when not seeking the next enemy to pulverize with his fists.

Tropes associated with Yellow Zelkova:

  • A Father to His Men: Implied as the soldiers under his command seem to share his enthusiasm for victory.
  • Affably Evil: He gets his hands dirty more than any other commander, fighting against Sonic and nearly destroys them multiple times. Contrasting with this are his dull wit and moments of being absolutely goofy (Eggman tattoos anyone?), and when he isn't in the middle of combat, he's quite chummy with his peers.
  • Barbarian Longhair: He's revealed to have pretty long hair, which seems to naturally come with adult Seedrians.
  • 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.
  • The Brute: If his frame wasn't a good enough indicator, he isn't very bright but is the most willing to get into a brawl (and the most capable).
  • Card-Carrying Villain: Has stated himself to be evil a few times.
  • Cyber Cyclops: His eye is more wide and visor-like. That said, he has a more traditional one on his forehead, which may make this a subverted case.
  • David vs. Goliath: His dynamic with Knuckles is akin to this, especially given Yellow Zelkova's massive stature at 12'2.
  • Disney Villain Death: After his fight with Knuckles he falls into a volcano, visibly catching fire on the way down.
  • 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.
    • Took a Level in Dumbass: It is implied in a flashback that he used to be reasonably intelligent, though it seems to have faded over the years.
  • Dying Curse: Declares Dark Oak will be victorious and avenge him before he falls to his death.
  • Evil Is Hammy: Pick ME! I shall be the representative for this TROPE!
  • Face Death with Dignity: He refuses Knuckles' attempt to save him and lets himself fall into the volcano whilst smiling, albeit while declaring Dark Oak will get his revenge.
  • Front Line General: Not so much as leading his troops into battle as lead only himself into battle.
  • Good Old Fisticuffs: Unlike the other Metarex, he fights with his massive fists rather than any weaponry.
  • Go Out with a Smile: He smirks proudly even as he falls to his death.
  • Horned Humanoid: His horns are incredibly broad, angular and flat. As a Seedrian, they're still yellow but somewhat branch-like.
  • Killed Off for Real: He falls into the lava in his last appearance and dies.
  • Muscles Are Meaningful: He's the absolute biggest character that isn't an outright monster of sorts and very strongly built; he serves as The Brute for the Metarex.
  • Pet the Dog: He claims 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).
  • Psychopathic Manchild: A few scenes paint him as this, such as his giddiness over showing Sonic & friends his temporary Eggman tattoo and his overall rash behavior.
  • Unrobotic Reveal: In his final appearance, once his armor is destroyed, he is revealed to not be a robot, but a giant lizard-like alien, who is also the same species as Cosmo.
  • Villainous Breakdown: Suffers one as he fails to defeat Knuckles and after he knocks his armor off.
  • You Gotta Have Blue Hair: His hair is revealed to be a grassy shade of green. It's subverted as, for a Seedrian, it's a perfectly reasonable hair color to have.

     Red Pine
"We don't know how to thank you: Perhaps, we'll just destroy you!"
Voiced by: Hochu Otsuka (JP), Jonathan Todd Ross (EN), Antoine Nouel (FR)

The first of the Metarex commanders introduced outside of Dark Oak, Red Pine has the dubious honor of the shortest screentime of the lot, only physically appearing in his debut episode.

Tropes associated with Red Pine:

  • Attack! Attack... Retreat! Retreat!: After rushing in to destroy the compromised Metarex base, he has this moment when Super Sonic & Super Shadow created a gravitational force.
  • Battleship Raid: His fleet and battleship make up much of the direct conflict of "A Metarex Melée" besides the ongoing fight with Dark Oak. It's downplayed however as his squadron isn't ever really fought directly but rather the compromised Metarex base where Sonic and Dark Oak were fighting is the main event.
  • Big Red Devil: Evokes this visually with his maroon armor and large horns.
  • 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.
  • Cruel and Unusual Death: For the Mauve Shirt of the bunch, he has the rather brutal fate of having his ship slowly pulled into a gravitational force before it explodes while he's onboard, with no hope of escape.
  • Cyber Cyclops: Evokes this the best among his peers, besides Dark Oak himself. That said, he has a second orb in a socket on his forehead, possibly subverting this like Yellow Zelkova.
  • Evil Is Hammy: He would have probably been just as hammy as Yellow Zelkova if he survived past his first appearance. This applies for both sub and dub.
  • Evil Sounds Deep: In both versions, moreso in the dub but he sounds especially booming in the sub.
    • Evil Sounds Raspy: It's very evident with his dub voice where he sounds cartoonishly evil.
  • 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.
  • Genius Bruiser: Allegedly, he was around Yellow Zelkova's strength and was a careful leader. We never get to see this.
  • Guttural Growler: He sounds like this in the dub.
  • Horned Humanoid: Four horns in his case, angular like Yellow Zelkova's but not nearly as massive.
  • Mauve Shirt: Quite literally, too. Between the other commanders, he served the smallest role and was killed off quickly, but did bring several plot points with him, such as the existence of the other commanders in the first place.
  • Out-of-Character Moment: Noted In-Universe by Yellow Zelkova and Pale Bay Leaf. He was always a careful commander, which intrigued Pale Bay Leaf because of how recklessly he acted during his final moments.
  • 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.
  • Smug Snake: Introduces himself by flaunting the successes of the Metarex' plans, thanking the heroes for their help before announcing their incoming defeat. He doesn't even survive past the episode, not even getting a chance to actually fight directly.
  • Starter Villain: The first of the Metarex commanders to be fought and subsequently destroyed, his existence primarily a reveal for the fact that there are a few more of them than expected.
  • The Unfought: He never got a chance to fight the heroes directly, being introduced on his battleship which would also be where he would die without ever moving from.
  • Unrobotic Reveal: In "The Lost Planet / Eye Spy", just like his fellow Metarex commanders, he is the same species as Cosmo.
  • We Hardly Knew Ye: He is only shown in the episode where he gets killed and doesn't appear again outside of flashbacks.

     Black Narcissus
"It's all a matter of brainpower; you see, it's impossible to vanquish a powerful opponent, unless you understand him!"
Voiced by: Ken Narita (JP), Sean Schemmel (EN), Antoine Nouel (FR)

Arguably the most infamous of the Metarex commanders besides Dark Oak, Black Narcissus is a a cruel manipulator of the highest caliber, even to those powerless against him.

Tropes associated with Black Narcissus:

  • Avenging the Villain: Declares that he will do this for Red Pine, even if it would go against Dark Oak's orders.
  • The Blank: Subverted. He appears to have an actual face of sorts below the signature Metarex "eye", unlike his comrades.
  • Blood Knight: A more subtle example compared to Yellow Zelkova. In his first appearance, he declared he had effectively conquered a planet much too easily, while also demanding to be the one to have Sonic's head, even if it would be against Dark Oak's orders.
  • Boom, Headshot! / Off with His Head!: How he and Pale Bay Leaf seemingly bite the dust as Final Mova.
  • Co-Dragons: 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.
  • Cyber Cyclops: His signature Metarex eye spans almost the entirety of his head and is ovular in shape.
  • Dark Chick: Disregarding his gender, he plays the symptoms of the trope very well, a skilled and deceptive manipulator whom also happens to primarily be a non-combatant.
  • Dark Is Evil: Decked out in black with bits of purple, and among the most diabolical of the Metarex commanders.
  • Deadpan Snarker: He has his moments. One standout is when Chris throws down a flash bomb and runs off with Cosmo. Black Narcissus hasn't moved an inch from his chair as he dryly quips,
    ..Eugh. This is the most dismal escape attempt that I've ever seen. I'll give them a head start to try and add some excitement.
  • Evil Genius: 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.
  • The Fighting Narcissist: The mirror on his staff allows him to invoke this while on the battlefield.
  • 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.
  • Horned Humanoid: More like antennae compared to the horns of his fellow commanders.
  • Kubrick Stare: If one chooses to believe his real face is below the large "eye", then he's got a perpetual one.
  • Lean and Mean: The second tallest of the Metarex commanders at 10'9 and rather thinly built compared to, say, Red Pine or Yellow Zelkova.
  • Manipulative Bastard: Seems to be his hat and prefers to plot and scheme over diplomacy (Pale Bay Leaf) or brute force (Yellow Zelkova).
  • Meaningful Name: Named specifically after the narcissus, it's namesake being a man who was incredibly vain and obsessed with himself, and in one version of the tale, couldn't get his eyes off his own reflection. Not only is Black Narcissus quite vain himself, he has a massive mirror on his staff so that he can always admire himself in the midst of battle.
  • Muscles Are Meaningful: An inverse example compared to Yellow Zelkova; he's quite lithe and is shown to be surprisingly inept in combat.
  • Narcissist: If the entire page hasn't tipped you off.
  • Non-Action Big Bad: Because of his laughable fighting strength, he usually spends his time scheming and planning things out.
  • Revenge: A subtle but key trait with Black Narcissus is how he holds grudges. He declared he would avenge Red Pine more boldly than even Yellow Zelkova and was all for getting at Chris and Cosmo as payback to Sonic, one of Red Pine's murderers. After being humiliated by Eggman's goons in combat, he declares to his face that he'll never be forgiven even while he's on the Metarex' side for the time being.
  • Sadist: It's clear he enjoys torturing the victims of his schemes.
  • Simple Staff: His weapon is a large staff with a mirror at the end of it.
  • Slouch of Villainy: He's lounging in his chair while awaiting for Cosmo to fall for his ploy.
  • Soft-Spoken Sadist: In the sub, he has a very gentle and quiet voice.
  • The Stoic: Most prominent in his debut in the Japanese version, practically never raising his voice and speaking calmly and analytically.
  • Took a Level in Badass: Could go toe to toe with Rouge and Knuckles when he returns with Pale Bay Leaf and Dark Oak.
  • Unrobotic Reveal: Just like the other Metarex commanders, he is the same species as Cosmo.
  • 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).
  • Would Hurt a Child: While none of the Metarex are above this, Black Narcissus is a special case because he stabs Chris in the stomach!

     Pale Bay Leaf
"We'll be watching, and when they least expect it, we strike again; and this time, we'll destroy them!"
Voiced by: Jurota Kosugi (JP), Jim Napolitano (EN), Antoine Nouel (FR)

A brilliant tactician, Pale Bay Leaf is the Metarex commander most often actually observing political affairs; most prominently, resistance fighters trying to rebel against them.

Tropes associated with 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).
  • Big Creepy-Crawlies: Pale Bay Leaf is more overtly insectoid than the rest of the commanders, looking like he took some design cues from a cricket or a mantis.
  • The Blank: Possibly outright averted, as he has eyes in more conventional placements and a semblance of a mouthpiece.
  • Boom, Headshot! / Off with His Head!: How he and Black Narcissus seemingly bite the dust as Final Mova.
  • The Chessmaster: One of the single best characters in the series in that regard. For bonus points, in one episode he's relaxing during a mission by playing chess with a rook-shaped drone, and for his voice actor in the dub to be an actual puppeteer.
  • Co-Dragons: Shares this with Black Narcissus to some extent, and they are the only commanders of the original 4 remaining when Dark Oak activates forestation.
  • Creepy Long Fingers: He has unnecessarily long and very thin fingers.
  • Deadpan Snarker: He can certainly have his moments, much like Black Narcissus.
    Pale Bay Leaf: You misjudge him. His endgame was weak. But then again, he's not like someone I know who relies solely on power.
    Yellow Zelkova: What?
  • Dual Wielding: Could do this with swords he can summon at will.
  • Evil Genius: Of a different shade to Black Narcissus, focusing rather on diplomacy and tactical brilliance over his contemporary's more direct manipulation skills.
  • Evil Laugh: Can pull off an insane one quite well.
  • Evil Sounds Deep: Especially in the Japanese version, where he has quite the baritone.
  • Extra Eyes: Unlike the others of his clan, he runs with this and runs with it hard, having two eyes in more "conventional spots" alongside the more traditional in the middle of his head and three more running down the middle of his torso, giving him the most eyes of all the Metarex.
  • Faux Affably Evil: He regularly acts calmly and in a professional manner, such as referring to his argument with Yellow Zelkova as a "difference of opinion over tactics". Despite this, he's arguably the most terrifying and sadistic of the Metarex commanders.
  • 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.
  • Green and Mean: The green Metarex commander, and he can have his moments of cruelty.
  • Hero Killer: Pale Bay Leaf has the possible honor of the highest onscreen kill count by an antagonist in Sonic X, his fleet being responsible for Molly's death and personally overseeing the torturous execution of the remaining Resistance members, including Leon.
  • Horned Humanoid: His horns in particular are the longest of them all.
  • 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 to Black Narcissus "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.
  • Lean and Mean: The skinniest of the Metarex generals (though the second shortest at 8'9), and very much evil.
  • Manipulative Bastard: More of the diplomatic type (as opposed to Black Narcissus' behind the scenes plotting).
  • Muscles Are Meaningless: The skinniest of the generals, yet still capable of noselling Sonic’s attacks.
  • Not Himself: Noticed that the usually cautious Red Pine's plan of attack was unusually different during his final mission.
  • Odd Name Out: Only name that’s 3 words. His color isn't explicit either even if it's still apt (pale green, as in his armor), though one can argue "Green Bay Leaf" would be rather redundant with their theme naming.
  • Rewarded as a Traitor Deserves: Inflicts this to Leon after having been given a fake Chaos Emerald, eliminiating the remainder of the Resistance.
  • Third Eye: The only one of the Metarex commanders to don these.
  • Unrobotic Reveal: Just like his fellow commanders, he is a male member of Cosmo's species.

    Final Mova 
Voiced by: Joji Nakata (JP), Matt Hoverman (EN), Antoine Nouel (FR)

The result of Dark Oak and his remaining Metarex commanders fusing into a giant plant-like creature as part of the forestation project to eradicate all non-plant life in the galaxy.

Tropes associated with the Final Mova:

  • Botanical Abomination: It's a massive hydra made of plantlife, with its necks terminating into roots that encompass a planet. It's further forms are a colossal, appalling looking seed, and finally a compressed core.
  • Final Boss: The last threat faced by Sonic and his team in the finale and the entire series.
  • Fusion Dance: Dark Oak, Pale Bay Leaf, and Black Narcissus fuse into this monstrosity with the aid of the Planet Eggs and Chaos Emeralds. Presumably, if they were still alive, Yellow Zelkova and Red Pine could have likely added to it as well.
  • Genius Loci: A giant sentient plant that has Dark Oak's consciousness even after losing two of its heads.
  • Multiple Head Case: In its first form, it has three dragon-like heads, each with the matching colors of Dark Oak, Pale Bay Leaf and Black Narcissus. Even after Black Narcissus and Pale Bay Leaf are destroyed by the Sonic Power Cannon, Dark Oak's head is absorbed into Final Mova.

Season 3 Heroes

Voiced by: Etsuko Kozakura (JP), Amy Birnbaum (EN), Marie Lenoir (FR)

A plant-like alien and allegedly the last of her kind, Cosmo joins the core cast in the second season, striving to defeat the Metarex responsible for destroying her homeworld. She forms a romantic bond with Tails.

  • Break the Cutie: She started off pretty fractured, the rest of the series finished her off.
  • The Cameo: A possibly unconfirmed one in Sonic Chronicles as the potted plant by the window on the top screen in Tails' workshop.
  • The Chosen One: Sorta, though we don't know about it until near the end.
  • Cool Big Sis: What she thinks of Galaxina.
  • Cute Monster Girl: Cosmo and the female Seedrians, in comparison to their large, brutish male counterparts.
  • Famous Last Words: Her spirit's parting words to Tails are equal parts touching and heart-wrenching: "I'll always love you".
  • Floral Theme Naming: Her entire race has this.
  • Flowers of Nature: She is a plant-like alien with flowers on her head. They start off as buds, but bloom into flowers when she matures.
  • Green Thumb: She has some kind of affinity with Planet Eggs: in a moment of desperation, she inadvertently uses one to summon vines to defend herself.
  • Go Out with a Smile: Her last scenes involve her spirit smiling happily as she bids her friends goodbye.
  • Heroic BSoD: When she suddenly remembers why Dark Oak called her the ultimate Metarex spy, "White Seed".
  • Heroic Sacrifice: Tails actually had to be the one to finish her off. And he was NOT happy about it.
  • It's All My Fault: All over the place. Try not to count a time where she hasn't blamed herself for her friends getting hurt.
  • Someone Has to Die: That final episode made Tails into a Woobie all by itself.
  • Sorting Algorithm of Deadness: Could very well have turned out to be on the low end if Sonic X hadn't ended right after she died - that plant she left behind could be a means for her to regenerate.
  • Theme Naming: Cosmo's species are all named after plants in the subbed version, whereas the dubbed [4kids] version used space-themed names.
    • The Metarex have plant-based names which makes sense, since Dark Oak and the other leaders are male members of Cosmo's species
