skinwalker, “He who walks in the skin,” is an English word that loosely translates the Navajo term Yenaldooshi o Naglooshi, which literally means "with it, walk on all four". Both of these definitions refer to a particular type of "shapeshifter" in Navajo folklore, a sorcerer able to assume the forms of different animals by wearing their skin. The Skinwalkers they can transform into wolf, deer, crow, owl or even into fireballs darting in the sky, but the most recurrent metamorphosis associated with them is that of coyote. The result is a monstrous hybrid that roams the wastelands of the southwestern United States at night, bringing pain and torment to humans. The Skinwalkers they can move at great speed, so much so as to equal a speeding car, but their movements are never completely natural: the footprints they leave on the ground are uncoordinated, and there are those who say they have seen them run backwards, with limbs twisted into impossible positions.
