Doctor Eggman

Dr. Ivo Robotnik, better known as Doctor Eggman, is a fictional character and primary antagonist of the Sonic the Hedgehog franchise.

Dr. Eggman is Sonic the Hedgehog's arch-nemesis, and a rotund mad scientist who plans to conquer the world to build his own Empire. While he has gone through several major and minor appearance changes throughout the series, his in-game designs retain several basic characteristics, such as his egg-shaped body, red-black-yellow clothing, bald head, a onesie, pince-nez sunglasses, and large mustache. Eggman commonly creates machines and robots, including a wide variety of Badniks. Notably in early games, he has also served as a recurring boss, appearing in almost every level piloting one of his created vehicles.

 * Doctor Eggman (addressed as Doctor Robotnik) is a guest crossover antagonist in Marvel's Spider-Man: Webbed Champion, voiced by J. K. Simmons. He appears in episode "Legendary Universes, Part 3: Unlimited Speed", on which he seeks to regain control of a reanimated EggRobo, and retake Jarvis's robot body, leading him to a intense conflict with Sonic and the Freedom Fighters and Spider-Man's team of Champions. This version of Robotnik is shown to be an amalgam of his counterparts from the 2006 Sonic the Hedgehog video game (from where Robotnik is visually based upon) and the 2020 film (where Robotnik runs his technology company on Earth).
