Momo is the only known Winged Lemur. Avatar's co-creator Bryan Konietzko admits that Momo is his favorite character to draw and that his body language is derived from memories of a childhood cat. Much like Appa, Momo is the last of his kind in the show. Momo was introduced in the episode "The Southern Air Temple". In the episode Aang finds him at the Southern Air Temple and then keeps him as a pet. Although Momo has been in many dangerous situations while traveling with the protagonists, he has also been of aid to them and a source of comic relief throughout the series. According to the creators, Momo was intended to represent the spirit of Aang's mentor, Monk Gyatso.
