Wolf spirit

The wolf spirit was a ferocious beast who attacked Team Avatar when they were traveling to Hira'a.

History
When Team Avatar was traveling to Hira'a in search of answers to finding Zuko and Azula's mother, Aang began feeling a strange urge to constrict his face, feeling the presence of the wolf spirit. He briefly saw the wolf spirit a short while after, before being distracted by Azula's quick desertion. The wolf spirit then appeared again, this time, it tried to eat Sokka's head. When Aang tried to respectfully approach the spirit and reveal his position as the Avatar, the wolf spirit quickly attacked Aang. Team Avatar tried multiple ways of attacking the wolf spirit, all to no avail before Appa swiped the wolf spirit with his tail. The wolf spirit then threw up a cloud of moth wasps that quickly surrounded Team Avatar, before Azula struck all the moths with a bolt of lightning and scaring off the wolf spirit.
