Skin-walker

In some Native American legends, a skin-walker is a person with the supernatural ability to turn into any animal he or she desires. To be able to transform, legend sometimes requires that the skin-walker wears a pelt of the animal. In most cases, this pelt is not used in modern times because it is an obvious sign of them being skin-walkers.

Similar lore can be found in cultures throughout the world and is often referred to as shapeshifting by anthropologists.
