Therianthropy

Therianthropy is the magical ability of human beings to metamorphose into other animals by means of shapeshifting. Therianthropes also known as were-creatures are known and are located throughout the world. The most common type is the werewolf though other types such as werebears, werecats, werehyenas, and even werebeasts are known to exist, all of which if given time can control their abilities, though none can resist transforming on the full moon.

Most therianthropes exhibit superhuman strength, endurance, and stamina as well as shapeshifting. Killing a therianthrope generally requires either a magical metal, like silver, decapitation, and/or burning. The origins of Therianthropes are a matter of some debate.
