|Dr. Eggman Nega|
|First Appearance||Sonic Rush|
Eggman Nega is Dr. Eggman's human alternate dimension counterpart, existing in the same dimension as Blaze the Cat who is his arch enemy. Eggman Nega made his first appearance in Sonic Rush and has since appeared in other games. He has been a main villain in every game he's appeared in so far and is even more evil than Eggman himself whom he betrays in Sonic Rivals by turning him into a card.
Eggman Nega's goal is exactly the same as Eggman's; he wishes to rule the planet by any means.
