To be both a successful pawn shop owner and an extra-terrestrial gun dealer, you have to stay cool and not lose you're head—sorry, couldn't resist. Most of the people on this list are heroes and immortals, tasked with some special mission or saddled with some inner drive that keeps them moving past the grave and towards their goals. Jeebs, on the other hand, is just a small-time crook who regenerates his head.

It's a nifty approach to casual immortality—his regeneration isn't unlike recovering from a stubbed toe or a paper cut. Jeebs uses his abilities quite nefariously: He isn't afraid to get underhanded in his dealings. Because, hey, what's the worst that can happen?
