This one is not RP related because I ran out of ideas. Instead this is more of a personal concept thing based on some interpretations of wendigos being somewhat beastly looking, so i took it a step further. This is an evil spiritual entity that collects the skins of animals that it has killed and wears them, taking on the properties of the animal in the process. It wears multiple pelts all the time and can take on different aspects of multiple animals at once.
