Eggman Nega

Eggman Nega is a minor antagonist in the Sonic the Hedgehog series who first appeared in Sonic Rush. He is a human scientist and the descendant of Dr. Eggman from approximately 200 years into the future, though he initially introduced himself as Dr. Eggman's alternate reality counterpart from Blaze's world.

He is the primary nemesis of Blaze the Cat and Silver the Hedgehog.Dr. Eggman Nega's design appears reminiscent of the older design of Dr. Eggman prior to Sonic Adventure, albeit with the colors reversed, a longer nose, a white mustache (suggesting he is at an elderly age), pointy blue sunglasses, and visor-styled goggles instead of normal ones.
