Windigos



Windigos are horse-like spirits that first appeared in the episode Hearth's Warming Eve. They feed off of hatred and create blizzards. The more hatred is available, the colder and more powerful their blizzards become. Eventually, the ponies whose hatred they feed off of will become as frozen solid as their hearts. The blizzard that these creatures created was partially responible for the land of Equestria's founding

Windigos are based off of a creature from Algonquian myth called the Wendigo. Wendigos were said to be cannibalistic spirits who could shapeshift and possess people.
