Dr. Eggman

Dr.

Eggman is the primary antagonist in the Sonic the Hedgehog video game franchise—a rotund, mustachioed mad scientist who builds robots and schemes to conquer the world.

Originally called Dr.

Robotnik in Western releases, Eggman became his official name globally, though both names persist among fans.

His egg-shaped body and egg-themed machines give him his name: Every level ends with another ridiculous Eggman contraption.
