Navajo Skinwalker Although it is most frequently seen as a coyote, wolf, owl, fox, or crow, the yee naaldlooshii is said to have the power to assume the form of any animal they choose, depending on what kind of abilities they need.
Skinwalkers - 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.
Coyotes in Native American Lore: Skin-walker Native American (Yeenaeldooshi - "with it, he goes on all fours" - Navajo). Usually described as being naked except for a coyote skin or a wolf skin. Said to be impossible to catch and agile, these creatures can transform into an animal to travel large distances or just to wreck havoc. Wild animal hides are taboo, and rarely seen in Navajo culture because of their association with the Skin-walkers.
