Werewolf
From The Dark Shadows Wiki
A Werewolf is a supernatural creature that resembles a hybrid of a human being and a wolf. It is savagely dangerous, but only exists (usually) during the three nights of the full moon. The rest of the time, a werewolf is nothing but an ordinary human being. However, in human form, the werewolf sometimes sees a sign that someone is destined to be attacked by them--a pentagram visible only to the werewolf.
Evidently, only men can be werewolves. The only demonstrable means of becoming a werewolf is to be cursed by a witch or (presumably) a warlock, or to be the descendant of another werewolf (whether this is true of all werewolves is as unknown).
Werewolves can only be killed in their beastly form by silver weapons such as silver bullets or a silver-headed cane. If killed in human form, the werewolf will become the animal and stay that way permanently (944).
Leviathans are afraid of werewolves.
Werewolves do not remember what happens while in their bestial state. They do remember, however, the beginning of their transformation.
