The wendigo is often said to be a malevolent spirit, sometimes depicted as a creature with human-like characteristics, which possesses human beings. It is said to cause its victims a feeling of insatiable hunger, the desire to eat other humans, and the propensity to commit murder. In some representations, the wendigo is described as a giant humanoid with a heart of ice, whose approach is signaled by a foul stench or sudden unseasonable chill.
