Wendigo

For the Marvel Comics character, see Wendigo (comics). For the 2001 horror film, see Wendigo (film) The Wendigo (also Windigo, Windago, Windiga, Witiko, and numerous other variants) is a malevolent cannibalistic spirit into which humans could transform, or which could possess humans, appearing in Algonquian mythology. Humans who indulged in cannibalism were at particular risk, and the legend appears to reinforce this practice as taboo.

[Native American] The Wendigo is a monster who comes from the coldest place. He is composed of mud and ice. A cannibal, he will devour anything in his path, including another Wendigo. His mouth is lined with jagged teeth and he is magic, able to change form at will. One warrior defeated a Wendigo by changing himself into a giant dog.
