Werewolf horror is not so much a subgenre as it is a story element.
There are commonly two types of werewolves. The alpha werewolf is born a werewolf. When the alpha werewolf bites a human and doesn't tear them to shreds, the victim turns into a werewolf which is the beta werewolf. In early stories, werewolves change from humans to their wolf form when the full moon is visible in the sky. In a lot of tales, the werewolves can be killed with silver. When the beta werewolf is in its wolf form, it has no human awareness, it only acts on instinct which is often hostile. Sometimes the werewolf is looked at as a horrid villain that needs to be slain. In other contexts, the werewolf is a victim that cannot help their affliction.
