i'd have to say vampire because vampires would so kick zombies a**es and if the zombies started to take over the the vampires could just fly away untill the zombies ran out of brains to feed on whereas the vampires could just fly down and feed on the zombies.. .. .. ..
actually what would happen if a vampire did feed on a zombie or a zombie ate the brains of a vampire would you get some new kind of strange vampire-zombie race would the still be mindless would they still have all the vampire/zombie strengths or weakness' :?: hmmmm
