"Skin-walkers are perhaps best documented among the beliefs of the Navajo tribes. The Navajo believe that the Skin-walker, more commonly referred to as Yenaldooshi, is an evil human being who has gained the supernatural power to assume the form of an animal through breaking cultural taboo. More specifically, a person is said to gain the power of a Skin-walker by murdering a close relative. Skin-walkers are often described as naked wanderers, who wear nothing but the skin of an animal, wandering the community by night spreading misery and desecration everywhere they go. Skin-Walkers are also often found in Norse folklore, that speak of a person who can travel in the shape of an animal to learn secrets and take on certain animalistic traits. The most common example, found in Norse folklore, of a Skin-Walker is that of a warrior who takes on the strength and stamina of a bear!"
