Dr. Eggman: Hedgehog Nemesis
"Dr. Eggman, the mustached, goggle-wearing antagonist from "Sonic The Hedgehog," takes a break from his World-conquest mission to attend the weekly Bad-Anon meeting."
Dr. Eggman sports a long, straight red-brown moustache with black eyes with red pupils and goggles above his head. He wears blue glasses, a red coat with yellow cuffs and white spots and a white zipper over a black suit that goes down to his feet. He has a circular face, round body and white gloves.
- Unlike his nemesis, Eggman does not have a speaking voice in Wreck-It Ralph. However, in the 1993 animated series Sonic the Hedgehog, he was voiced by Jim Cummings, who has worked with Disney voicing (among others) Winnie the Pooh, Tigger, and Captain Pete.
- This was due to Mike Pollock, Eggman's current voice actor in the games in addition to recent animation (notably Sonic X and Sonic Boom), not being informed of the recording sessions.
- Eggman is seen fighting Sonic in the Chemical Plant Zone of Sonic the Hedgehog 2, though the machine he is piloting (the Flame Mobile) originates from Sonic 3 & Knuckles.
- Even though Dr. Eggman is seen in his artwork from Sonic Adventure, the only Sonic arcade games are him in his original design, alternatively known as Dr. Robotnik.
