Sonic X/Characters

Sonic's World Inhabitants

Sonic the Hedgehog

The Ace: Leans more as this as the show progresses, especially due to his more one dimentional role and the majority of the cast's idolization of him.
Ace Pilot: Proved to be this when he flew the X-Tornado.
Always Someone Better: A lot of characters convey an amnosity towards him because of his bravado and popularity, Eggman, Knuckles and the Chaotix in particular have recurring jealous rivalries towards him.
An Odd Place to Sleep: Has a tendency to sleep on rooftops, balcony guards, the wing of the X-Tornado and even on top of a castle battlement in one instance.
Beware the Nice Ones: When he becomes "Dark Super Sonic" in response to seeing Chris and Cosmo get hurt.
Big Brother Mentor: To Chris. Also while not as much as he usually is in other continuities, he has his moments with Tails.
Big Damn Heroes: Pulls this off Once an Episode.
Breaking the Fourth Wall: The character most likely to pull this off.
Brilliant but Lazy: Spends most of his time lazing around, and only sets off to defeat the Monster of the Week at the last minute.
Catch Phrase: In the Japanese version, he tends to exclaim "Oh shoot!" whenever something goes wrong.
Chick Magnet: He's shown to have many fans, including fangirls.
Creepy Monotone: His voice becomes this when he becomes "Dark Super Sonic", right before tearing the two Gold and Silver Metarex new ones. The sheer difference between his normal voice and this voice is extremely creepy
Deadpan Snarker
Demoted to Extra: A lot more episodes are played from Chris or another heroes perspective, with Sonic acting more as something of a friendly Aloof Ally who only steps up when the Monster of the Week appears. The comics play him more as the main hero, though he later leans as a Hero Antagonist due to Eggman's expanded role.
Determinator
The Everyman: Started as more of an Idiot Hero, but became more of this as the series progressed. The comic tones him back down to his initial wackier persona.
Golden Super Mode: The only animation adaptation so far to include it.
Gratuitous English: At least Once an Episode, at least in the Japanese dub.
Green Eyes
Heroic Safe Mode: Almost permanently.
Improbable Piloting Skills: Makes you wonder why he didn't fly the planes more.
Invincible Hero
Lightning Bruiser: He has Super Speed, can bust through robots with ease, and can take quite a bit of damage.
Lovable Rogue
Made of Iron: He appears to be capable of taking immense physical beatings and yet get back up nearly every single time.
Men Don't Cry: Cries in episode 52, but his eyes are hidden from view when he does.
No Guy Wants to Be Chased: He doesn't like being smothered with affectionate attention, either by Amy or by his human fans.
Real Men Wear Pink: He seems to hold a strong appreciation for flowers.
Screw the Rules, I'm Doing What's Right
Signature Move: Spin Attack.
Sleepyhead: Often found sleeping on Chris' roof.
Super Speed: Naturally.
Super-Powered Evil Side: Although it didn't make him evil, just more aggressive.
Vitriolic Best Buds: With Knuckles.
Walking the Earth: Although he spends a lot of his time at Chris' home, he's quite often shown travelling the world in his spare time.
Weaksauce Weakness: He can't swim.
Why Did It Have To Be Water?: Usually infallably collected and mellow, in the face of even a puddle of water however he becomes a frantic Nervous Wreck.
You Gotta Have Blue Quills

Miles "Tails" Prower

Ace Pilot
Adorkable
All of the Other Reindeer: He used to be bullied for having two tails, though Intelligence Equals Isolation was part of it as well.
Blue Eyes
Cheerful Child
Child Prodigy
Cool Plane: The X-Tornado.
Cunning Like a Fox
Adorably Precocious Child
Demoted to Extra: To an extent. His role as Sonic's right hand man is seen a lot less in favor of the latter's bond with Chris. He gains a more prominant role in the third season however and the comics also use his sidekick role more often.
The Everyman: Despite his genius intellect and occasional Cheerful Child traits, he is mostly little more than the Nice Guy of the group. He is developed slightly in the third season, though it's still kinda hard to define his personality.
Flight: Though he very rarely uses his trademark tail-flight, he often pilots the aircraft the team is using.
Fur Of Gold
Gadgeteer Genius
Humble Hero
Intergenerational Friendship: Most of his friends are a lot older than him, but his friendship with Chuck takes the cake.

Knuckles the Echidna

Adorkable: He tends to be shy and awkward around girls.
Belligerent Sexual Tension: With Rouge.
Butt Monkey: Prone to slapstick, and often the butt of gags from the rest of the team (often owed to his loner attitude). You know you're low on respect when even Cream The Rabbit mocks you. This is downplayed in the comics, though he's still kinda bumbling in tone.
The Comically Serious
The Complainer Is Always Wrong: Even when he has a valid point...
Cute Little Fangs
Determinator
Dreadlock Rasta
Dumbass Has a Point/Jerkass Has a Point: He very antagonistic to Sonic due to the latter being partly responsible for them being sent to Earth and leave their home world, and often points out this specific flaw in Sonic's character. While no one really gives a shit about his opinion, he makes a rather strong point there.
Fiery Redhead
Green-Eyed Monster: Jealous of Sonic's freedom, popularity, and carefree nature.
Grumpy Bear
Gullible Lemmings: Both Eggman and his own friends explot this at times.
Hair-Trigger Temper

Vitriolic Best Buds: With a lot of the cast due to his brash attitude and Butt Monkey status, but especially with Sonic and Amy.
Walking the Earth: Before joining Sonic and Co., Knuckles travelled around on his own to find his way back home.
The Worf Effect: The most likely of the heroes to fall to this, to the point he hardly ever won a battle without teamwork or an outside interference.
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.

Amy Rose

Action Girl
Badass Normal
Berserk Button: Ruining the moment between her and Sonic, or suggesting he doesn't return her feelings.
Bob Haircut
Bratty Half-Pint: Usuually rather pleasant and compassionate, when riled up however she can be rather sulky and obnoxious, if not outright violent and intimidating. This got taken Up to Eleven in later episodes.
Catch Phrase: In the Japanese version; "{{[[[What the Hell, Hero?]] SONIC, YOU IDIOT!!!}}"
Clingy Jealous Girl
Cute and Psycho: She's a nice bubbly girl, but her Hair-Trigger Temper and Tsundere mood swings sometimes come across as a bit... unhinged. Just about everyone is scared of her when she's angry.

Fan Girl

Tsundere: Type B.
Violently Protective Girlfriend
Vitriolic Best Buds: Can be this to a lot of the cast due to her brash attitude, but especially clashes with Knuckles.

Cream the Rabbit & Cheese

A Rabbit And Her Chao
Badass Adorable: Occasionally. The rest of the time she has to settle for just being adorable.
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.
Bow Ties Are Cool: Cheese.
Brown Eyes
Cheerful Child
Cowardly Lion
The Cutie
Deliberately Cute Child: During the baseball game, she uses her cute charms to distract Eggman's pitcher.
Damsel in Distress: Her being captured by Eggman and Sonic going to save her is the reason they got sent to Earth in the first place.
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.
Fragile Flower
Free-Range Children: Vanilla, like her games counterpart has no problem with Cream's adventures and rather nonchalently 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.

Heroic Sacrifice
Humans Are the Real Monsters: His initial attitude until he remembers Maria's true wish.
Invincible Villain --> Invincible Anti-Hero: Even moreso than Sonic.
Jerkass Has a Point: His attempt to kill Cosmo, while unnecessary, did make a lot of sense due to the Metarex literally using her as a living walky talky.
Ki Attacks: Chaos Spear is a mix of this and Shock and Awe.
Large Ham
Lightning Bruiser
Multicoloured Quills
Perpetual Frowner
Person of Mass Destruction: When he fought the Meterex Fleet alone after Molly's death and the ending of season two where he warp a blast that would destroy the universe.

Signature Moves: Chaos Control and Chaos Spear.
The Stoic: But has occasional moments where he's Not So Stoic
Sugar and Ice Personality

Ultimate Lifeform
The Unfettered: Compared to his games counterpart, this version of Shadow is racked far less with doubt and moral conflict, and will attack and even kill to reach his goals in a completely stoic tone.
Well-Intentioned Extremist: Frequently.

Topaz

Villains

Dr. Eggman

Adult Child
Affably Evil
Animal Cruelty is Just Wrong: Given the fact he's seen kidnapping animals, Eggman draws the line on animal cruelty.
Anti-Villain: Essentially becomes one as the series goes on. Taken even further in the comic.
Badass Moustache
Bad Boss: Treats Decoe, Bocoe, and Bokkun quite badly at times, although it's Played for Laughs and he has occasional Pet the Dog moments with them.
Bald of Evil
Beware the Silly Ones: Sometimes. In the earlier episodes at least he is feared by the humans, with a lot of his plans coming off as genuinely deadly until Sonic intervenes.
Big Bad
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.
Cloudcuckoolander
Determinator
Ditzy Genius
Egopolis: He wants to make the world into Eggman Land, whether Sonic's world, Earth, or both!
Enemy Mine: Teams up with the heroes when a bigger threat comes along.
Even Evil Has Standards

"It's one thing to take people prisoner and threaten them, but when you hurt somebody, that's going too far."

Evil Genius
Evil Is Hammy
Evil Virtues: He's very hard-working, and never gives up.
Fat Bastard
Friendly Enemy: Has moments in the anime with Sonic, took Up to Eleven in the comics. People rarely bat an eyelash at him and his mooks appearing at a pool party.
Goggles Do Nothing: Never wears them.
Gonk: Looks more cartoony than most of the humans in the show.
Harmless Villain: Increasingly so as the series goes on.
Heel Face Turn: Has a very brief one in the comics due to taking to his profession as popular wrestler, El Gran Gordo.
Ineffectual Sympathetic Villain
It's All About Me
Large Ham
Laughably Evil
Mad Scientist
Morally-Ambiguous Doctorate
Noblewoman's Laugh
Opaque Lenses
Paper-Thin Disguise: Utilizes these a fair few times in the comics, most notably with El Gran Gordo. Only Sonic tends to see through them.
Robot Master
Stout Strength: Once beat up a bunch of crocodiles and broke a mechanical lazer 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).
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

Blue Eyes: Bocoe.
Combining Mecha
Deadpan Snarker
Expy: Of both Scratch and Grounder and Omega and Epsilon.
Fat and Skinny
Heel Face Turn: Briefly became butlers to Chris when Eggman treated them poorly and the heroes treated them kindly. It only lasted two episodes, however.
Ineffectual Sympathetic Villains
Mecha-Mooks
Minions With An F In Evil
No Indoor Voice: Bocoe shouts everything in the original Japanese.
Red Eyes, Take Warning: Inverted. Decoe is a villain, but a rather harmless Minion with an F In Evil for the most part.
Sissy Villain: The two display rather effiminate and whiny habits at times, and near strictly butlers for Eggman rather than programmed for any physical work.
Those Two Bad Guys
Vocal Evolution: The two bots are voiced in a stiff Robo Speak in early episodes of the English dub. Throughout the first season, while their overall pitch and synthetics remain largely the same, they gradually fluctuate into emotional human-like acting similar to their Japanese voices.

Bratty Half-Pint
Cloudcuckoolander
Dark Secret: His crush on Cream.
Deadpan Snarker
Expy: Of Coconuts.
Eyes of Gold
Keet: Has the personality of a rambunctious child.

E-Series

Arrogant Kung Fu Girl: E-91 Lady Ninja, from what brief sentience she shows.
The Fool: Pretty much E-77 Lucky's premise.
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

Co Dragon: Briefly acts as one alongside Chaos to Eggman, following his brothers "demotion".
Heel Face Turn
Heroic Sacrifice
Minion with an F In Evil: Gamma is a robot, so most of "evil" actions owe to following Eggman's orders. As he gains emotions, he becomes increasingly empathetic and ultimately turns sides.
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.

Drunk with Power
The End of the World as We Know It: He removed planets' Egg, allowing the planets to wither and die.
Even Evil Has Loved Ones
