5. Neron

(Underworld Unleashed, DC Comics)

Well, I've got a deal for you"¦

Neron is the DC Universe's resident trickster demon. He has a thing for fluorescent green, which looks so freakin' good when printed.

Neron had what was actually a pretty solid plan. He gathered up a bunch of d and e list supervillains and promised that he could give them upgrades for one cheap price: their souls.  And some of them took him up on that deal. But in the end, the combined might of Captain Marvel and The Trickster brought him down, and that was the end of Underworld Unleashed. He popped up again a bunch of times, most recently in the Midnighter and Apollo miniseries. But his costume was so flippin' great, and he's always been one of my favorites.

Dude was the nineties-ist devil you ever done saw. And hey, anyone who turned Killer Moth into a literal giant moth monster deserves some credibility.
