where did the marvel zombie virus come from
Marvel Zombies Within the Marvel Multiverse is an alternate Earth designated Earth-2149, which contains alternate versions of Marvel superheroes. The story begins as an unknown superhero from another dimension, brought by the "Hunger", crash lands before infecting the Avengers. The infection spreads via contact with the blood of the victim, usually through a bite by an infected individual. The zombie super heroes largely retain their intellect, personality and their super powers, although they are consistently driven by the "Hunger" for human flesh. As the story begins, the Marvel Zombies have already devoured all non-transhuman human life on Earth and are now without food (as prefigured in Marvel Zombies: Dead Days, a later tie-in).
