Skinwalker

The skinwalker, known in Navajo as yee naaldlooshii (literally "with it, he goes on all fours"), originates in the folklore and religious tradition of the Diné (Navajo) people of the Southwestern United States, centered on the Navajo Nation across present-day Arizona, New Mexico, and Utah. The figure belongs to the broader Navajo category of witchcraft known as the Witchery Way ('ánt'įįh), whose practitioners are termed 'ánt'įįhnii, of which the skinwalker is the most feared and best known type outside the culture.

A skinwalker is understood to be a person, usually described as a witch or medicine person who has turned to evil, who has gained the ability to transform into, possess, or take on the appearance and abilities of an animal, most commonly a coyote, wolf, fox, owl, or crow. In many tellings the transformation is achieved by donning the pelt or skin of the animal in question. Accounts describe skinwalkers moving unnaturally fast, running on all fours even in partially human form, and being sighted at night along roads or near homes, where their eyes are said to reflect light abnormally when caught in a vehicle's headlights or a flashlight beam.

The central taboo said to grant this power is the killing of a close family member, often a sibling, as an initiation rite into the witchcraft society, which marks the skinwalker as having committed the gravest violation of Navajo kinship and moral order. Powers attributed to skinwalkers in various tellings include shapeshifting, superhuman speed, mimicking the voices of loved ones or animals to lure victims, cursing or causing illness and death at a distance, and reading the minds of those they target. In some tellings a skinwalker can be wounded or killed if struck, and the wound will appear on the person's human body when they are later encountered, exposing their identity. Because the subject is considered genuinely dangerous and sacred within Navajo religious life, many Navajo people regard it as taboo to discuss skinwalkers in detail, especially with outsiders, and the topic has been extensively sensationalized and distorted in non-Navajo popular media, a distortion that many Navajo commentators and scholars have specifically criticized.

Interpreting the folklore through a behavioral lens, the skinwalker is defined by a will to power achieved through the deliberate inversion of communal bonds rather than through open confrontation. Its intelligence is calculating and predatory, oriented toward concealment, patience, and exploiting the trust of its former community rather than toward direct combat. Where it appears in accounts, it operates alone and at night, approaching occupied homes and vehicles rather than avoiding human contact entirely, which suggests a motive of intimidation and predation over simple survival. Its emotional register in these stories is dominated by malice and contempt for the kinship ties it betrayed to gain its power, with little indication of remorse. Because the figure is fundamentally a corrupted human being rather than a natural animal, its cunning and adaptability are portrayed as higher than an ordinary beast's, while its moral standing is portrayed as the lowest possible within the tradition's own framework.
