The wendigo is a demonic creature appearing in the legends of the Algonquin peoples along the Atlantic coast of the United States and Canada, and the upper Midwest United States. The wendigo is probably my state's only popular mythic character. Michigan's weather apparently doesn't suit many supernatural beings. As it happens, the wendigo doesn't mind our cold weather at all, and that's why it was found here and in most northern states. According to Algonquin legends, a wendigo is an insatiable, yet emaciated, beast that desired for nothing but the taste of human flesh. All wendigos were humans at one time, but had resorted to cannibalism and thus turned into this dreaded beast. Humans could also turn into wendigo's if they became too greedy or ravenous. If you were unlucky enough to run into one in the woods, it would devour you without hesitation. Wendigos were seen as a gaunt looking giant, a being that is always hungry. The fear of turning into a wendigo kept many Algonquin people from consuming too much or taking more than they needed. While greediness was looked down upon, cannibalism was extremely taboo in the Algonquin tribes. You either committed suicide in the event of famine, or resigned yourself to death. Eating someone, even to save your own life, was one of the worst things you could do. So it's easy to see why the Algonquin came up with a creature that represented all that could go wrong when you committed such acts. You weren't a human anymore, just an insatiable monster gorging itself on the flesh of your comrades.
Real monster or not, the wendigo has become a popular villain in many TV shows, video games, and movies, including Cabin in the Woods, Supernatural, Final Fantasy, Dungeons and Dragons, and Hannibal.
