Dr. Eggman is a self-proclaimed evil genius with a comically high IQ of 300. He is a portly man, easily recognized by his massive, bushy brown mustache, bald head, and signature goggles. He typically wears a red and yellow coat. Despite his intelligence, Eggman is incredibly arrogant, short-tempered, and prone to childish outbursts and tantrums whenever his elaborate schemes are foiled.
