Yeah, in the comics, the Robotnik we see now (commonly called Eggman) is different from the one in the beginning of the comic series. I learned that from the Free Comic book day issue of Sonic the Hedgehog.

@Hazlenaut: Thanks for the info I haven't read sonic in a while

@BlackArmor: In the Archie comics there are others. Eggman aka Robo-Robotnik aka Robotnik 2 is from another reality the same reality that cyborg sonic is from. When Robotnik died in endgame Robo-Robotnik took his place. he seeks to takeover Mobius Prime. He either seeks a challenge as he already kill Sonic before he was born and the Acorn Kingdom or want to make sure his victory is his own and no one but his. Nega-Eggman at this time is at war with the Zone Cops. In short Robotnik prime is dead Robotnik 2 took over his world and killed his Sonic2 by Robotnik primes knowledge now wants to takeover Mobius prime and defeat Sonic Prime.

Wait I thought Robotnik died in an explosion of his own creation and then Snively awakend a clone of him (the clone being Eggman) from a hall with like 20 or 30 diffrent clons of him. So what's this about Eggman being from another dimension I thought Nega-Eggman was the only Eggman from another dimension
