Although not traditional anime, this series is an American anime with martial arts, comedy, and a really good lesson. The story is about air benders, fire benders, earth benders, and water benders. They are basically skilled people who know how to use their body to control the four elements through concentration and practice. A young pair of siblings, Katara(who is the last water bender of her people) and Soka, living in the south polar country of a fictional world. They come across a boy named Aang and his giant flying bison Appa, who happen to be frozen in a big bloc of ice. For 100 years(during that time a terrible war broke out between the Fire Nation and all the rest of the world). Oh yeah, and Aang is the very last air bender and is also the Avatar, the almighty powerful being who can control all four elements. Together, Aang, Katara, Soka, Appa, and the new addition Momo (a flying lemur) travel around the world so Aang can learn all for elements before the Fire Nation concurs the war, and also avoiding a whiny banished Fire Nation prince who wants to kidnap Aang and imprison him so that he can return home. I really recommend this series, it matures as Aang and the gang matures and teaches awesome morals to kids.
