Top Zombie Killers:
Father Grigori. he's just a insane othodox catholic preist with converse sneakers and a lever-action rifle. His one-liners arent one-liners, either, they're verbose benedictions that no one else can manage. I'm not a big fan of religion (like saying bill gates is a little nerdy) but the man is an undeniably effective zombie-hunter).
Master Chef, if flood count. He has a shotgun, a single blast of which will insta-kill any flood in nearly any form. It does seem kind of cheap, though. He has killed absolutely rediculous numbers of the damn things, though
Ash Williams. Best Weapons. Best One-liners. Best Enemies. Best Chin.
He's more like a heroic fantasy-type hero, though, in that he mostly kills demon zombies and skeletons, and weird undead mutant things. never conventional zombies (slow, moany, or fast and screamy, they have to be brainless, and relatively non-supernatural).
