Encyclopedia Entry:
Beast-women with batlike features that live in caves and other dark places. They hang from the ceilings of their homes and wait for animals or humans to pass beneath them.
When a human male comes within her range, a werebat will dive from out of the darkness, knock him down, and forcibly mount him. Sadistic by nature, a werebat will respond to resistance or pleading by escalating the violence of the rape.
