WereWolf
A werewolf, also known as a lycanthrope (from the Greek λυκάνθρωπος: λύκος, lykos, "wolf", and ἄνθρωπος, anthrōpos, "man"), is a mythological or folkloric human with the ability to shape shift into a wolf or an therianthropic hybrid wolf-like creature, either purposely or after being placed under a curse or affliction (e.g. via a bite or scratch from another werewolf). This transformation is often associated with the appearance of the full moon. Early sources for belief in lycanthropy are Petronius and Gervase of Tilbury.
