A technological genius whod developed virtually outwordly technologies and inventions, hailed as the only man on Earth leagues above Iron Man's prowess in engineering. However, he'd soon went to criminal activties after he'd saw potential in world domination, and the effort of taking valuable resouces.

Soon enough, Dr. Eggman became a super-villain, ony ever stopped by the Avengers, but has been stopped numerous time by Spider-Man.
