Werewolves are human beings or non-human beings that transform into a canine-like humanoid under the full moon. They appear in two of King's works, including IT and Cycle of the Werewolf. It transforms into a werewolf to scare Richie Tozier after he had watched I Was a Teenage Werewolf. Lester Lowe was also a werewolf and was killing residents of Tarker's Mill, Maine. Both are harmed or killed with silver.
