Skeleton

Skeletons are the supporting frames of the bodies of living creatures. However, they are also a common type of monster in various forms of fiction. In most fiction, skeletons of dead creatures can be reanimated after a creature's death through the use of necromantic magic or by being possessed by souls of the deceased. The methods and reasons for reanimation often vary, but in a great many stories, reanimated skeletons will terrorize the living and even actively seek harm towards them.
