Werewolves (classified Type 3) are a post-human supernatural species which, during the full moon every month, transform into fearsome, monstrous, wolf-like beasts. In their human form, a werewolf cannot be distinguished from normal humans, although their senses of smell and hearing seem to sharpen before and after the full moon. The werewolf curse is normally passed on when a human is scratched by a transformed or transforming werewolf.
