One of several varieties of hunting-bat engineered by Human vampires, these creatures are bred completely immune to vampirism as they may otherwise compete with their masters for blood.

   Bred as a hunting companion, this large and powerful beast can go where its breeders cannot, unperturbed by vampire-specific psionic and chemical defenses. Though omnivorous, it actually prefers to eat fruit, leaving more blood and meat for the true vampires.

   Chiraptor harbor an intense hatred of bat-vampires (known simple as "The Sinister") which enjoy taunting and tormenting these and other domesticated bat mutants.
