Werewolf

Mythological human with acquired ability to transform into a wolflike creature

In folklore, a werewolf, or occasionally lycanthrope, is an individual who can shape-shift into a wolf, or especially in modern film, a therianthropic hybrid wolf-like creature, either purposely or after being placed under a curse or affliction, often a bite or the occasional scratch from another werewolf, with the transformations occurring on the night of a full moon. Early sources for belief in this ability or affliction, called lycanthropy, are Petronius (27–66) and Gervase of Tilbury (1150–1228).
