Polar Bear

A Polar Bear was one of the Beasts of Narnia. It is not known if they could talk. But if not, they were tamed by Jadis.

In the Disney adaption to The Lion, the Witch, and the Wardrobe, Polar Bears were pulling the White Witch's chariot. When Oreius the Centaur charged toward Jadis' chariot, the Polar Bears tried to claw Oreius only for him to jump out of the way.
