#4. Marvel Zombies 2
Written by Robert Kirkman, illustrated by Sean Phillips and Arthur Suydam

You have to give it up for a company that would take its flagship properties — I'm looking at you, Wolverine, Iron Man, the Hulk, Spider-man, Captain America — and turn them into flesh-eating zombies. A comic where Spider-man eats Aunt May and Mary Jane? That's a comic with the courage of its convictions. The Marvel Zombies series takes place in an alternate world where every hero is infected with a zombifying illness: They crave human flesh and they can't die. The key is that the 'heroes' actually retain their sentience, so they appreciate the horrific nature of their actions, they just can't calm their insatiable hunger for human flesh. The result is a genuinesly subversive orgy of Sadean cruelty, wherein most of the living beings in the universe perish. Good clean fun.
