     The Heroes 

Sonic the Hedgehog

  • Badbutt
  • Big Brother Instinct: Probably the most emphasized usage of any Sonic incarnation. He looks out for Tails constantly and regularly goes frantic the moment something happens to him.
  • Blood Knight: One of the nicest ones there are. He always loves a good challenge and fighting (without killing) Robotnik, but the moment Robotnik (falsely) claims that he has given up his life of crime, Sonic accepts it though a bit disappointed and hopes to find something equally exciting.
  • Catch Phrase: "Up, over and gooone!", "I'm waaaaiiiiiiitiiiiiing…", "Gotta speed, keed!", "You got it ace - let's race!" amongst other rhyming phrases.
  • Chick Magnet: Tends to have a lot of fangirls.
  • The Chosen One: He was apparently prophesied to save the kingdom featured in "Hedgehog of the Hound Table", if the legend of the Holy Hedgehog is any indication.
  • Comically Invincible Hero: Handily outsmarts and overpowers Robotnik and his goons for Laughs. There are occasional points the joke's over and Robotnik gives Sonic a rough time however.
  • Determinator: Even the odd time his foes give him a genuine challenge, Sonic is not one to back down.
  • Friendly Enemy: He at least tries to keep Robotnik's henchbots from hurting themselves in the "Sonic Sez" segments.
  • Guile Hero: Achieves victory through his wits just as often as his speed.
  • The Hero: Since he's the protagonist.
  • Heroic RROD: Very rarely, but yes, Sonic can be tired out. Exploited for Robotnik's Evil Plan in "Mass Transit Trouble".
  • Hidden Depths: As corny as the Sonic Sez segments are, he shows this at times in them. In one he talks about how great reading is, and in many others he shows genuine concern for the safety of children.
  • Karmic Trickster: The show nudges Sonic's characterization into this category, where he uses all sorts of mental tricks and misdirection to deflate Robotnik's plans.
  • The Kirk: This incarnation of Sonic enjoys adrenaline-inducing activities like his games counterpart, but is shown to take rules and responsibility seriously, as is shown in the Sonic Sez segments and his relationship with tails. Many of his antics are also intellectual as well as physical.
  • Knight in Shining Armor: Takes up the mantle of the legendary "Holy Hedgehog" in "Hedgehog of the Hound Table".
  • Mr. Vice Guy: Occasional overconfidence.
  • Paper-Thin Disguise: Much of Sonic's disguises are this. One's just Sonic with a hat and a bag of mail, and they fall for it.
    • Lampshaded by Sonic when, to his alarm, sufficient doses of downloaded ninjutsu allow Scratch and Grounder to see through a disguise.
      • Also in the episode Grounder the Genius twice. The first time Sonic visits the fortress as a "Chip Recycler" and looks for the genius chip. Grounder says he has it which Sonic tries to get him, however Grounder, now being a genius, petrifies him aware that this would happen. Another example is later where Grounder makes out a trap and tosses it away far before anything bad happens. Sonic takes off his disguise and Grounder states he already knew Sonic was going to pull that.
    • At one point, Sonic even winks at the audience while showing himself through disguise.
    • In "Too Tall Tails" Sonic actually takes off his disguise midway through one of his schemes. Scratch and Grounder still don't recognize him!
      • Dr. Robotnik actually does manage to see through the majority of Sonic's disguises, however the few times he does it is either a few moments too late, or he's too far away to tell Grounder and Scratch, the ones typically being tricked.
  • Parental Substitute: To Tails, who happily accepts that Sonic's his "mom, dad, and picket-fence".
  • Race Lift: Type 5. Simply put, Jaleel White didn't want Sonic to sound too black.
  • Required Secondary Powers: Without his shoes, Sonic cannot use his Super Speed without burning his feet.
  • Rhymes on a Dime
  • Sharp-Dressed Man: Sonic in some of his disguises counts for this.
  • Smug Super: At times.
  • Teen Genius: Sonic has his moments of this.
  • Totally Radical
  • Trademark Favorite Food: Chili-dogs.
  • Walking the Earth: His home is never shown and he travels a lot.

Miles "Tails" Prower

     The Badniks 

Dr. Ivo Robotnik

Scratch & Grounder

Robotnik's newest, dedicated anti-Sonic robots and general minions. Unfortunately for him, they're both total incompetents and idiots. Created at about the same time from the same machine, they would originally have been identical, but Scratch pulled a lever that caused Grounder to come out with a different chassis. Both Badniks are based off of badniks from Sonic the Hedgehog 2; Grounder is a straight lift of the Grounder badnik (itself a lift of Burrobot from the first game), while Scratch is a heavily modified Clucker (a turret-firing chicken badnik).

  • Affably Evil: In "Grounder The Genius" when Grounder gains super-intelligence, he also gains a considerable amount of charm to his personality.
  • Annoying Laugh: Scratch: "Ba-HA ha-HAAAA!!"
  • Arm Cannon: Grounder
  • The Bully: They are occasionally seen harassing random Mobian citizens for no good reason and once they even attempted to beat up an old (and seemingly weak) crane.
  • Card-Carrying Villain: Both, but Scratch takes the cake what with being very vocal about cheating and proud about it.
  • Chew Toy: They have been blown up, frozen, melted, run over, squashed, tied together… at least half of the humor in the show revolves around them getting turned into spare parts by Sonic.
  • The Ditzes: Scratch is only slightly smarter than Grounder, which isn't saying a whole lot.
  • Dirty Coward: Scratch resembles his master very much on this, being a bully who likes to pick only on those whom he deems as weaker than him and being quite open about it being more fun.
  • Do-Anything Robot: Scratch and Grounder are full of all sorts of tools, up to and including inflatable supermodel decoys.
  • The Dog Bites Back: Though usually undyingly loyal to Robotnik, there are odd times they attempt revenge over his abusive treatment of them.
  • Evil Laugh: Scratch's rooster laugh, which sounds like a trumpet.
  • Expy: Of C-3PO and R2-D2. Scratch is tall and bossy, like 3PO, while Grounder is short and full of hidden gadgets, like R2.
  • Fat and Skinny: They're not organic beings, but they contrast appropriately in appearance.
  • Genre Blindness: Sonic tricks Grounder and Scratch endlessly all the time with various disguises, yet as far as they seem to know there's just a lot of hedgehogs all over the planet with a series of different and very diverse jobs. Although Scratch does see through his disguises from time to time.
  • Gone Horribly Wrong: For Robotnik, anyway. They were intended to be hyper-competent Super Soldiers who could easily defeat Sonic; instead, they're Lethally Stupid clowns who Sonic runs circles around and outwits on a regular basis.
  • Heel–Face Turn: In an inversion of Criminal Amnesiac Scratch temporarily turns good in "Blank-Headed Eagle" when he suffers amnesia and thinks he's a superhero named Edgar Eagle, whom he surprisingly admired.
  • Ineffectual Sympathetic Villain: While Robotnik could at least strive to be fearsome every now and then, Scratch and Grounder were completely incompetent for the large majority of the time, when not being defeated easily by Sonic, their plans were taken apart by random civilians or even their own bumbling.
    • Not-So-Harmless Villain: They had odd times they could act out Robotnik's plans competently. "Mass Transit Trouble" has them successfully Out Gambit Sonic and escape for example.
  • Jerkass: Scratch towards Grounder, often venting his frustration when the latter's stupidity results in Sonic's plans succeeding. Given Robotnik's treatment of the two, this might be understandable.
  • Laser-Guided Tykebomb: The Super Special Sonic Search and Smash Squad. This combined with Goldfish Poop Gang. Robotnik created Scratch and Grounder for the express purpose of hunting down and killing Sonic, but since the two have only a quarter of a brain between them, Sonic always ends up the winner.
  • The Magnificent: Listening to how Scratch and Grounder address Robotnik is one of the best parts of the show. Such as "Your Masochisticness".
  • The Millstone: Whenever one of Robotnik's plans fail, it's typically because of their bumbling.
  • Minion with an F in Evil: Averted most of the time, what with them being vicious bullies, but they have their moments when Robotnik's not around, such as in "Blank-Headed Eagle", where they're shown to be huge fans of the heroic "Edgar Eagle" TV character.
  • No Indoor Voice: Scratch's incredibly loud, braying voice.
  • Ridiculously Human Robot: They manage to produce tears in Sonic's Song.
  • The Pollyanna: Considering how abusive and uncaring their father-figure is, it takes a special kind of obliviousness to feel optimistic and believe they can be his favourites.
  • Screams Like a Little Girl: Scratch, especially in the German dub.
  • Simpleton Voice: Grounder
  • Smug Snake: Grounder, when he temporarily becomes a genius.
    • Scratch seems to have a high opinion of himself half the time.
    Scratch: He made me persistent! He made you too dumb to quit!
  • Swiss Army Weapon: Grounder
  • Terrible Trio: Robotnik is the leader; they're the two minions. They also sometimes play as such with Coconuts.


One of Robotnik's earlier creations; pushed aside in favor of Scratch and Grounder, Coconuts yearns to re-earn Robotnik's attention and affection and so often works independently of his "little brothers", though he will work with them if he must. Coconuts' name and design are lifted directly from the "Coconuts" badnik of Sonic the Hedgehog 2.

  • Advertised Extra: He appears in the opening, but stars in only 17 episodes, roughly a quarter of the series.
    • Ascended Extra: He appeared more regularly than Scratch and Grounder in the Archie comic series.
  • Boisterous Weakling: He is pretty aggressive for a pint-sized monkey.
  • Butt Monkey: Takes abuse most of the time simply for existing despite his rather extreme effort and enthusiasm, getting demoted constantly for mostly nothing…and it's not like Scratch and Grounder have it good either.
  • Catchphrase: "Yeah! YEAH!"
  • The Ditz: Memorable moments include believing Sonic that he would let him hit him and trying to shoot Sonic with an automatic weapon when he was standing on him.
  • Glory Hound: There is noone more persistent and more obsessed than him in proving himself to the Doctor.
  • Ineffectual Sympathetic Villain: He's slightly more savvy and crazy than Scratch and Grounder, though still very much a pitiful bumbler. And even at that he just wants Robotnik's approval.
  • I Work Alone: He sometimes works as a Terrible Trio with Scratch and Grounder, but more often desires to make his own solo missions to prove his superiority, even sometimes sabotaging their's so he can take full credit.
  • The Millstone: His egotism and shortsightedness has done more bad than good to his own team.
  • Smug Snake: He's a more pitiful case than standard examples, but he's still fairly assured he's smarter than Robotnik's other minions and his next plan will definitely get him on his boss' good books.
  • Terrible Trio: When he works with Scratch and Grounder.
  • The Unfavorite: Gets it much worse than Scratch and Grounder, which is really saying something.

Lesser known bounty-hunters who got easily tricked by Sonic and reappeared in Dr. Robotnik's Mean Bean Machine




  • Adorable Evil Minion: Some of them are kinda cute but his attitude makes him stand out.
  • Chew Toy: He is bandaged most of the time because he has balancing difficulties.
  • Nervous Wreck: The moment he sees his opponent he goes through a Freak Out.
  • Shrinking Violet: Despite fighting you he is described as shy and is quick to retreat to his shell the moment he loses.

Davy Sprocket


  • The Ditz: In the same way as Scratch and Grounder he got tricked by Sonic's poor disguise and fake carnival and fell from a cliff.
  • Drives Like Crazy: A literal road hog and very keen on using his tires.
  • Evil Is Hammy: This is probably the best example.
  • Evil Sounds Raspy: His "sizzling" voice must feel like sizzling your ears.
  • Gluttonous Pig: Having the form of a wheeled hog he expectedly, spews tons of food puns at you pre-battle.


  • Complexity Addiction: He is still incredibly difficult and can create incredibly large combos to end you, but the time he spends doing overly elaborate combos means it's easier to overwhelm him.
  • The Ditz: In the same way as Scratch and Grounder he got tricked by Sonic's poor disguise and fake carnival and fell from a cliff.
  • Mad Bomber: A given considering that he is a moving stick of dynamite.
  • The Napoleon: For someone so short he certainly has a short fuse.
  • Slasher Smile: Has a very wide one when he's winning which showcases his insanity.


Sir Ffuzzy-Logik


Other Robotnik Robots

  • A.I. Is a Crapshoot: At worst, some of Robotnik's droids can turn out to be disobedient or even worse, good willed. At best they are loyal but incompetent fools like Scratch and Grounder.
  • Ambiguous Disorder: The Music Destroyer was built with hyper-sensitive hearing and an extreme intolerance for music, as though he had misophonia.
  • Ascended Extra: A lot of Robotnik's earlier robots from the pilot appear as enemies in Dr. Robotnik's Mean Bean Machine.
  • Berserk Button: Don't ever play music around the Music Destroyer.
  • The Brute: Many of the one-episode badniks fit this role, being significantly larger and stronger than Scratch and Grounder, but possess otherwise unremarkable intelligence. Coachnik, Arnold Robonegger, and the Music Destroyer are all good examples of this.
  • Butt Monkey: Almost any robot made to commit evil by Robotnik is doomed to be humiliated and turned to scrap by Sonic.
  • Damn, It Feels Good to Be a Gangster : Ballhog and Roller were adapted for one episode with this persona.
  • The Gunslinger: The Despicable Desperados in "Magnificent Sonic", naturally using lasers in place of traditional pistols.
  • Living Prop: Many generic robots assist Scratch and Grounder in certain schemes, some with recurring designs.
  • Robot Of The Week: The biggest role these characters play.
  • Unwilling Roboticisation: Despite being more synonymous with the Sonic Satam version, Robotnik used this odd times in the show, notably in the Chaos Emerald four parter, where he does this to Blackbot the Pirate. However, AoStH is also notable for being the only DiC Sonic show to feature the more traditional "organic battery" form of Unwilling Roboticisation from the games (where an animal is encased in a robotic shell and used as an energy source, rather than have its flesh turned into metal as in SatAM and the Chaos Emerald arc), albeit only once in the episode "Pseudo Sonic," where the titular character is piloted by a diminutive mouse. Needless to say, the vast majority of Robotnik's Badniks in AoStH are not Unwillingly Roboticized, but constructed out of parts like any other robot.

     Other Characters 


A robotic female hedgehog created by Robotnik to run Sonic into an exhausted state by bending him around her little finger and sending him on impossibly long quests to please her. She has a change of heart when Sonic turns out to genuinely care for her and winds up joining a community of Robotnik's various "junked" robots.

Momma Robotnik

Robotnik's harridan mother, normally held safely away in the "Mobius Home for Really Bizarre Mothers" but who sometimes escapes to harass her son and everyone else. She looks almost identical to her son, but she's considerably larger (usually twice his size, depending on the scene) and much nastier.

Robotnik Jr.

An artificial son created by Robotnik to inherit his empire, since the alternative, giving it to Scratch, Grounder and Coconuts, is unthinkable to him. Unfortunately for Robotnik, he turns rebel against him and goes to live with Robotnik's other rejects, where he develops a crush on Breezie.

Wes Weasley

Collie Chang


An infamous intergalactic bounty hunter. When she meets Robotnik, she immediately falls in love with him and won't take no for an answer.


A cute little Blob Monster from another dimension. He becomes Tails' pet in "So Long Sucker!"

  • A Fox And His Alien: With Tails, although Sonic thinks he's too dangerous to keep around.
  • Berserk Button / Beware the Nice Ones: When he gets angry or hungry, he grows to enormous size and devours everything and everyone in sight.
  • Big Eater: The only thing that can satisfy his appetite is - you guessed it - chili dogs.
