Wendigo

Wendigoes are Dark spirits from Canada and northern parts of the USA that are strongly associated with winter, famine, and starvation.

Appearance
No one really knows what the original spiritual form of the wendigo looks like, but when they possess someone, the host tends to appear like a hybrid of whatever they were and an emaciated yeti. They will grow white fur on most of their body, claws on their hands and feet, fangs, red eyes, and their ears, if they don't already have this, will become pointed. Also their bones/ribs will show up through their skin, as if they were without food for several days.

Behavior
Wendigoes are extremely malevolent spirits that will possess others who, for whatever reason or another (to them the reason doesn't matter), have committed the taboo of cannibalism. Those possessed will have no mind of who they are, or anything, in fact. The only thought that those possessed have in mind is HUNGER. They will eat anyone that they get their claws on until they are killed, or until the spirit is banished from possessing the host.
