Eggman

Dr. Ivo Robotnik, better known as Eggman, is the main antagonist of the Sonic the Hedgehog franchise and its live-action film adaptation.

Early Life
Robotnik grew up as an orphan, causing him to resent family. In school, Robotnik was punched in the face by the resident bully, humiliating him. Instead of reporting him to the principal, Robotnik achieved revenge through technological means, causing the bully to spend the next year eating through a straw. At some point in his career he allegedly helped stop several coups in the Middle East.

How Sonic the Hedgehog Should Have Ended
Sonic gets help from his “new friends” to fight Robotnik so Robotnik summons his robot friends, the Badnik Carreys, which Sonic finds weird. Robotnik orders the Badnik Carreys to attack Sonic's friends and fights Sonic after Sonic reclaims his quill. After the Badnik Carreys' defeat, Wade simply shoots Robotnik to death.
