What the Heck is up with the people who created this page? Most of this info and the pictures should be removed because they refer to EGGMAN and not EGGMAN NEGA. Nega is not the exact same person as Eggman, so stop putting Eggman's information down here and put up only things that Eggman Nega has been confirmed of doing!
As a male fan of Scourge, I can say that it's because that he's such a jackass and unlike other "Evil Twins" who just try to defeat the original, Scourge took over his own planet just to differentiate himself from Sonic.
Personally, I think the best one is Scourge the Hedgehog, because unlike other evil twins who simply try to destroy their originals to be the original, Scourge took time off from trashing Sonic to take over his own universe to distance himself from Sonic the Hedgehog.
