Doctor Eggman (Dark Mobius)

Dr. Ivo Robotnik (born day 253, 3189), also known as Dr. Eggman, is a character that appears in the Sonic the Hedgehog comic book series and its spin-offs. He was an alternate version of Dr. Eggman from Dark Mobius.

Past
Eggman's early history was most likely largely the same as his Mobius Prime counterpart's. The point of divergence was when Knuckles became corrupted by his chaos powers and decided to conquer Mobius. During Knuckles' descent, Eggman was seemingly vaporized by the echidna.

Legacy
Knuckles later learned that he only thought that he vaporized Dr. Eggman, as he was not in complete control of his powers at the time. Eggman would end up being the first being that Knuckles took a Core from. It also took a great deal of experimentation to restore his body, which Knuckles would hang up as a trophy in the Citadel of Darkness. Knuckles never did like his Prelate form though because he thought its neon mustache was ridiculous.
