Dr. Ivo Robotnik, usually known by his alias, Dr. Eggman, is the main antagonist of the Sonic The Hedgehog series. He was originally called Dr. Robotnik in America and Europe, though his Japanese name, Eggman, has become his English nickname since Sonic Adventure; the name Robotnik, meanwhile, has been mentioned several times in Japan.

Character Description

Dr. Eggman is a mad scientist who seeks to rule the world by enslaving small animals in robots, but has always lost to Sonic and his friends, no matter how many plans he attempts. He is terribly immature as he tends to throw tantrums when he loses. He is also very vain as a lot of his robots resemble him. Lately he has taken a backseat, serving as comic releif, or as the initial villain before the true villain of the game is revealed. Examples of this include Sonic Adventure where Eggman is betrayed by Chaos, Sonic Adventure 2, where Eggman teams up with Sonic to save earth from the Space Colony ARK and the Biolizard, Sonic Heroes where Metal Sonic, his own creation, imprisons and impersonates him, and Sonic the Hedgehog (2006) where he is manipulated like the heroes by Mephiles. He has appeared as the final boss in the Sonic Rush games alongside his new accomplice Eggman Nega.
