Wendigo
In Algonquian folklore, the wendigo () or windigo is a mythical man-eating monster or evil spirit native to the northern forests of the Atlantic Coast and Great Lakes Region of the United States and Canada. The wendigo may appear as a monster with some characteristics of a human or as a spirit who has possessed a human being and made them become monstrous. It is historically associated with murder, insatiable greed, and the cultural taboos against such behaviours.
