Doctor Ivo Robotnik, better known as Doctor Eggman (ドクター・エッグマン Dokutā Egguman) or Classic Eggman (クラシックエッグマン Kurashikkuegguman), is an antagonist that appears in the Sonic the Hedgehog series. He is a human and Dr. Eggman's counterpart from another dimension set in the recent past, as well as Sonic the Hedgehog's arch-enemy. Like his counterpart, he is a selfish, self-proclaimed evil genius with an IQ of 300 who dreams of ruling the world with his army of Badniks. For all his brilliance, however, Eggman's plans are constantly thwarted by Sonic and his friends, who are always around to save the day. Basically a past version of his mainstream counterpart from his younger days, Eggman first appeared during the Time Eater incident where he teamed up with his counterpart to rewrite history in his favor, only to be stopped by Classic and Modern Sonic. Since then, Eggman has continued to follow his ambitions of creating Eggman Land.
