Mula

Mula is Avatar Wan's animal companion and a cat-deer. Wan first freed her from a trap, set by people looking to eat her. From that day on Wan and Mula became close friends.

History
When people from Wan's hometown were in the Spirit Wilds hunting for food, Wan saw her trapped. He freed her from the trap, and since then they shared a close bond. As Wan traversed the world, looking to learn the elements in order to defeat Raava, Mula journeyed with him.
