Concept: Muttering growls, these hungry unliving shells are no more The Grimm than you or I.  Somehow their instincts run deep, leaving some form of muscle memory.
Astro Zombies will do their best to gnaw at you with their teeth, claw at you with their hands and then feast on your brains. They'll do anything to feed their hunger.
