His skin color is a mixture of Violet hues (darkest from the top and brightest to the bottom) with Persian Indigo spots on his head. He wears a Black-Inch Worm robe and unlike his minions, he doesn't walk nor run but is always seen riding on his anti-gravity device which makes things faster for him.
He is the personal enemy of Agent Brains. An extraterrestrial villain who adores maths problems and with the biggest ego in the entire galaxy. Egghead will never admit that Agent Brains is more intelligent than him. He cannot bear to hear her name, and even less that of Fred, since he frustrated his plans to destroy the Earth, by sitting on his egg-control.
