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. Witches use the form for expedient travel, especially to the Navajo equivalent of the ‘Black Mass’, a perverted song (and the central rite of the Witchery Way) used to curse instead of to heal. They also may transform to escape from pursuers.
