Werewolves

Two types of werewolves have been sighted, although they're not different enough to warrant two separate categories. The first is the classic human turned werewolf. By being scratched or bitten by another werewolf, upon every full moon the human will turn into a humanoid wolf form and gain unimaginable power and speed. They are tough to take down, silver being the only known thing that can take them down for good.

The other types of Werewolves are huge wolves, not quite the size of Direwolves, who are usually responsible for creating the other variant of the species. They are much more savage, but they are stronger, faster, and even tougher to take down. Silver has been known to be either greatly effective or less effective depending on the abilities of said werewolf.
