Role Type: Major Antagonist

Voice Type: Medium-low to Low. If you’re going for imitations, then they gotta be either those of Deem Bristow OR Mike Pollock.

The Insufferable Genius. The Robot Master. The man who proves that sometimes, Humans Are the Real Monsters. The doctor who has tried Hijacking Cthulhu many times and has eventually succeeded.

The Emperor Scientist. The Fat Bastard Big Bad.

THE Recurring Boss.

He is the Eggman! (That's who he is!)

Big Bad of the series, eternal Arch-Enemy of Sonic the Hedgehog, patron saint of stuffing woodland creatures into robot soldiers, self-professed gentleman genius, neck-and-neck with Dr. Wily as gaming's most premiere Mad Scientist, and amusement park enthusiast.

Dr. Ivo Robotnik, better known to the world as Dr. Eggman, is a portly, mustachioed roboticist whose main desires are to impose his own view of a glorious utopia upon everyone and everything using his technology… which he would be able to do if he could just destroy the little blue rodent that keeps spin-dashing a hole into his plans.

While Dr. Eggman doesn't have a significant background, it's known that he looked up to his grandfather, Gerald Robotnik, and aspired to be a great scientist like him. Eventually, he decided his genius was enough to put him at the top of the food chain, and he's been trying to Take Over the World to establish an Eggman Empire ever since.

On the surface, the good doctor is very temperamental and childishly eccentric despite his stated IQ of 300 — he's quick to throw a fit of anger whenever things don't go his way, many of his robots have goofy appearances, and his ideal paradise appears to fall somewhere between a casino and a carnival. Don't be fooled, though, he's every bit as clever as he claims to be, able to create or exploit almost anything to further his goals, possesses quite a bit of cunning and planning to carry them out, and frequently sends Sonic running through zone after zone littered with his traps and mean machines.

Eggman's master plans of global (and potentially universal) conquest almost never change, and with his intellect, determination, and legions of robots, he's always willing to pull out all of the stops to accomplish his goals and destroy Sonic and his friends, matching the hedgehog's unstoppable physical prowess with his immovable evil genius, and surpassing him in ego a million times over.
