Part of the horrific appeal of the whole zombie thing is that it can happen to anyone. Your wife, your kids, your grandma, even that guy you buy coffee from, they can all shift from friendly humans to rotting, flesh-hungry undead in a matter of minutes, and suddenly it's shotgun time. (Aim for the head, kids.) So it's no surprise that the whole "no one is safe" thing has spread to the realm of fictional characters.
Zombie viruses are the great equalizer, after all. If it can happen to you, it can happen to Batman, or Spock, or Optimus Prime. (OK, maybe not Optimus, but it's fun to think about.) With that in mind, and for the 13th in our series of 31 posts for the 31 days of Halloween, we collected gruesome art featuring your favorite sci-fi characters transformed into shambling corpses that want your brains.
