Avatar: The Last Airbender

The story takes place in a war-torn, Asian setting where some characters have the ability to "bend" any one of the four elements—earth, fire, water, or air. As the only person who possesses the ability to bend all elements, Aang is known as the "Avatar" and is tasked with bringing peace to the globe from the Fire Nation. While being chased by the banished prince Zuko of the Fire Nation, who wants to restore his dignity by capturing the Avatar, Aang sets out to master the elements with the help of his new friends Katara and Sokka.
