Anamagqkiu
In Algonquian myths, the Anamagqkiu are underworld spirits whose chieftains are bears. They dragged Moqwaoi the wolf brother of the Great Hare, Manabusch under the frozen lake to his death. Manabusch revenged his brother death by killing the bear chiefs, but the other Anamakiu caused a great inundation that flooded the world.
