Snooping as usual, I see?!
~ Dr. Ivo Robotnik's most famous quote.
~ Dr. Ivo Robotnik's most famous catchphrase after being defeated.

Dr. Ivo Robotnik is the main antagonist of the cartoon Adventures of Sonic the Hedgehog. He is a more comical version of his video game counterpart, who similarly desires to conquer Mobius and destroy Sonic the Hedgehog. While he is nowhere near as dangerous as his many other counterparts he has made up for it with his melodramatic flair and absolute refusal to give up despite his numerous failings. He was also quite possibly one of the most insane Robotniks who ever graced the screen and has become both loved and hated by both fans and non-fans alike.

He is also extremely extravagant in personality, having gone as far as creating a giant golden statue of himself that takes pride and place right outside his main stronghold.

In the pilot, he was voiced by Jim Cummings, who would also voice his Sonic SATAM counterpart. In the series, he was voiced by the late Long John Baldry, who also voiced Komplex.


Dr. Ivo Robotnik is portrayed as a mad scientist and supervillain who has terrorized Mobius for years and although powerful enough to hold his own fortress (complete with a large gold statue of himself outside) he never amassed the power of any of his other versions. However he was just as persistent—if not more so—and had a true love of villainy. He was also the only version of Robotnik to reach super forms, such as Super Robotnik and Supreme High Robotnik.

Dr. Ivo Robotnik was also a genius despite his often idiotic behavior and created many hench-bots to aid him in his schemes to either take over Mobius, destroy Sonic or generally cause trouble - the most well-known of these hench-bots would be the trio of Scratch, Grounder and Coconuts who served their master loyally but were often in the firing line of his wrath should things go wrong.

Indeed, one of Robotnik's major weaknesses in the series was being extremely arrogant and almost always placing the blame for any failure on his underlings. He also despised anything nice and was very likely insane (for example he took pride in being called "ghastly" "fiendish" or "generally unpleasant").

Dr. Robotnik also had an equally insane mother who went by the name of Mama Robotnik. She was often cruel to her son and may very well have been the reason he turned to villainy in the first place as she was criminally insane and hated anything normal or pleasant (she also considered her son a complete failure despite his many attempts to please her).

Despite the more comedic tone of the character to befit the series' style, Robotnik demonstrated that he was capable of truly reprehensible actions. One notable case in the episode "Mass Transit Trouble" involved him sabotaging mass transit systems across Mobius with bombs that would kill all present-and theoretically distant enough that Sonic couldn't save everyone. In the clip show episode "Hero of the Year", he tricked Sonic into a trap and caged all of his friends aboard a sinking yacht, leaving them to be drowned.

Not to mention the countless times he kidnapped someone, notably Tails and Professor Von Schlemmer, and either forced them to work on a weapon intended for use against Sonic, or threatened to kill them. One particularly bad case involved him keeping his perceived romantic rival Lucas trapped in a cage for thirty years because Lucinda, a woman Robotnik loved and desired, cared about Lucas and wanted nothing to do with Robotnik.


Supreme High Robotnik

The Supreme High Robotnik

Supreme High Robotnik

Put them all together, it spells... the Supreme High Robotnik, master of the universe!!
~ Dr. Robotnik transforming into the Supreme High Robotnik via the power of the Chaos Emeralds.

The Supreme High Robotnik was the ultimate villain of the AoStH universe and an empowered Dr. Robotnik who gained godlike powers sufficient to rewrite the laws of the universe to his will.

Supreme High Robotnik was formed when the regular Robotnik obtained all 4 Chaos Emeralds and wore them together - upon transforming into a god, Dr. Robotnik hurled Sonic and Tails through time to the Big Bang itself. However this simply served to create a paradox of sorts that formed five Sonics and five Tails, the team of heroes then united to combat Supreme High Robotnik via stealing back the Chaos Emeralds and using them to undo all the madness Supreme High Robotnik had created.

After traveling through time and space, Dr. Robotnik obtained the four Chaos Emeralds (Invisibility, Invincibility, Immortality, and the Power of Life). By wearing all four emeralds together, Dr. Robotnik transformed into the Supreme High Robotnik. Hoping to finally destroy his enemies, he sent Sonic and Tails through time to the Big Bang. However, they returned with four additional Sonics and Tails from different points in time. The team of heroes that now consisted of ten all worked together to steal back the Emeralds and return them to their original places.

Powers and Abilities

Giant Supreme High Robotnik

The gigantic Supreme High Robotnik demonstrates his cosmic powers including the ability to grow in size.

In this state, Robotnik is granted power so great that he claims he could rule the entire universe, and possesses several reality warping powers. By wielding all four Chaos Emeralds at the same time, the Supreme High Robotnik has direct access to all the emeralds individual powers at once; With the Chaos Emerald of Invincibility and the Chaos Emerald of Immortality the Supreme High Robotnik is granted immeasurable strength, invulnerability and is successfully immortal, the Chaos Emerald of Invisibility allows him to turn himself invisible and the Chaos Emerald of Life allows him to animate anything. Other powers of the Supreme High Robotnik include sending victims back in time, shooting lasers from his handpalms and changing his size. While the Supreme High Robotnik does not have any weaknesses, he is still vulnerable to surprise attacks, and he will lose all his powers if somebody removes the necklace with the Chaos Emeralds attached to from around his neck.

Super Robotnik


Super Robotnik

This is like bending spaghetti.
~ Super Robotnik as he turns one of his prison bars into a pretzel and grinds it with his teeth.

Super Robotnik is a powerful supervillain ego of Dr. Ivo Robotnik. Dr. Robotnik falls into a tub of mixed cleaning chemicals that Coconuts makes but gains superpowers in the process and is mostly invulnerable. His weak spot is his own butt because it didn't get affected by the chemicals like the rest of his body did. After Robotnik transformed, he gave Coconuts a promotion to First Lieutenant for his actions, assigned him to recreate the super-strength formula, and demoted Scratch and Grounder. While Sonic and Tails are being served Chili Dogs for recovering a village's stolen goods, Super Robotnik arrives, first "shaking things up a little", then using his Super Freeze Breath, freezing Sonic and Tails, and throwing them to the frozen wastelands on the planet.

Super Robotnik later arrives back at his fortress, where Scratch and Grounder take inventory of stolen goods. Robotnik later tells them that Sonic should be escaping this very moment. Later, Coconuts has Scratch and Grounder assist him with the formula, but Coconuts creates a monster accidentally. After Scratch and Grounder throw ingredients into the formula that make it explode, Robotnik arrives, blaming them. Shortly after, however, he hears that the Four World Leaders are discussing on how to deal with him. Robotnik later captures the four, and tells Sonic that if he wants them released, he must defeat him in a gladiator battle. Tails later discovers his weak spot: his butt. Professor Von Schlemmer creates a powder that will penetrate Robotnik's butt and slowly negate his powers. He puts the powder on a cushion. Sonic disguises himself as a cushion salesman, and Robotnik steals that cushion from Sonic.

At the Gladiator Colosseum, Coconuts was unable to recreate the formula, so he gave Robotnik a Rump Protector. On the first two events, Robotnik was able to win with ease. However, in the final event, Robotnik's powers were finally neutralized, and he falls into the muck. He later re-promotes Scratch and Grounder so they can pull him out of the muck. But they fall in as well. Sonic wins, and Robotnik says "I hate that hedgehog!" quietly.

While most games feature a different version of Dr. Robotnik, the only game to ever have this particular incarnation of Eggman to appear in was Dr. Robotnik's Mean Bean Machine. He serves as the main antagonist and the final boss of the game with his own music (every other opponent has the same music). He is also the only character to have his own voice in the game: Laughing when he wins and yelling when he loses.

Sonic Live in Sydney


Ivo Robotnik as he appeared in Sonic Live in Sydney.

Robotnik later reappeared in Sonic Live in Sydney. In the musical, Robotnik escapes Mobius with the Chaos Emeralds and makes a new base in Sydney, Australia, prompting Sonic, Tails and Sally Acorn to follow him. After spying on his enemies, Robotnik devises a plan to kidnap Sally by giving her a pair of "Eggboots" and sings the song Give Me Chaos. After capturing Sally by freezing her, Robotnik unsuccessfully attempts to woo her, causing Sonic, who discovered Robotnik's lair thanks to the audience, to dress up as "Doctor Sonicstition" and offer him a love potion. After drinking the love potion Robotnik, proclaims his love for Sally, only to fall asleep as the "love potion" was actually a sedative. After Sonic disposes of his bomb, Robotnik escapes and presumably goes back to Mobius.





Snooping as usual, I see?!
~ Dr. Ivo Robotnik to his cohorts Scratch and Grounder (normally mistranslated as "Snoo-PINGAS").
How dare anyone interrupt me when I'm being vicious!
~ Dr. Ivo Robotnik
I'm not in trouble, I make trouble!
~ Dr. Ivo Robotnik
You lame-brained knuckle-dragging dork! How dare you interrupt me when I'm having a bath with my rubber crocodile?!
~ Dr. Ivo Robotnik to Coconuts
Sonic fell for it! Tails is ours! I'll have to give myself a prrrrrrromotion!
~ Dr. Ivo Robotnik
I know I lied, I know it's despicable and cruel. But despicableness and cruelty are my favorite hobbies.
~ Dr. Ivo Robotnik
I've called you all together because you're the worst assortment of low-life mercenaries I ever made! You're mean! You're malicious! You're MY kind of rotten!
~ Robotnik addressing his minions.


  • This incarnation of Robotnik has become the center of a slew of internet memes. One such meme is PINGAS, derived from his line: "Snooping as usual, I see?!".
  • Super Robotnik is obviously a parody of the DC Comics superhero Superman, and even has the same powers as Superman himself.
  • How Robotnik became Super Robotnik could be a reference to The Joker's origin story, as both fell into a tub of chemicals to become the very evildoers they are today.
  • This is the first televised version of Robotnik to be referred to as Eggman in western regions, and the second version overall (the first being his counterpart from the Archie comics).
