Eggman Nega

Eggman Nega (エッグマン・ネガ, Egguman Nega ?) is an alternate dimension version of Eggman, first introduced in Sonic Rush as the arch-enemy of Blaze the Cat.[83] Although his outward appearance resembles that of Doctor Eggman, his personality is different.[84] He is heartless and calculating, but maintains polite speech and manners.[84] His exact role in series varies; in the Sonic Rush series, he works alongside the main Eggman as a team,[85] while in the Sonic Rivals series, he tends to use the fact that he resembles Eggman to his advantage, letting Eggman take the heat for his actions.
