Shapeshifting, also referred to as Changing, is the supernatural ability to alter one's physical form.
Skinwalkers possess the ability to turn into any animal they desire.
Werewolves possess this ability to a certain degree and their transformation can be both voluntary or involuntary. When Werewolves experience extreme emotions or are effected by the Full Moon, their bodies will undergo several changes. The first sign of transformation in Werewolves is that their eyes will start to glow. Additionally, they will grow canine-like fangs and their brow ridge will become more pronounced. Their nails will increase in length and will become razor-sharp claws that can easily shred through skin and bone.
