Wendigo: 

The Wendigo originates from the Algonquin-speaking peoples, including the Ojibwe, the Saulteaux, the Cree, the Naskapi, and the Innu. It is a culture-bound syndrome called wendigo psychosis. It is 9 - 15 feet tall, a humanoid, emaciated-looking, gaunt giant, with a grayish complexion and sunken eyes. The creature stinks of death and decay; its desiccated skin pulled tightly over its bones. With its bones pushing out against its skin, its complexion the ash-gray of death, and its eyes pushed back deep into their sockets, the Wendigo looked like a gaunt skeleton recently disinterred from the grave. What lips it had are tattered and bloody. Its hunger for human flesh causes it to chew off its lips. Unclean and suffering from suppuration of the flesh, the Wendigo gives off a strange and eerie odour of decay and decomposition, of death and corruption. After resorting to cannibalism, usually in cold environments, a person's mind will be driven mad. This will cause them to act like a wendigo and the culture-bound syndrome takes over, causing them to change form. Their hunger changes their movements and their diets change their form. The Phylogenies of this species are of the Kingdom Animalia, the Phylum Chordata, the Class Mammalia, and the Order Primates.
