Deadpool because he's just an awesome character in general, Wolverine because he's lived for hundreds of years and is pretty strong, or the Hulk because he's a gigantic killing machine
the only problem with most of these heros is: they can turn into zombies (i read a comic where nearly every super hero and villian turned into zombies). another reason to chose death because she cant turn into a zombie or something else and is powerful enough to kill/defeat them all.
