Avatar: The Last Airbender is an American animated series, created by Michael Dante DiMartino and Bryan Konietzko. It ran for 61 episodes on Nickelodeon, and won a number of awards for its high-quality production. The show combined the styles of anime and American cartoons. Due to this style, the series regularly enters the conversation regarding its consideration as an anime work.
The protagonist, Aang, is a 12-year-old monk who is the Avatar, the only person in the world capable of manipulating, or "bending", all four elements. Together with his comrades, they explore the various nations of the world and fight the evil Fire Lord Ozai.
In addition to the show, there was an awful movie adaptation by M. Night Shymalan (The Last Airbender), a non-awful sequel (The Legend of Korra), and several video games and comics.
For questions about James Cameron's Avatar (which is unrelated), head on over to Movies & TV - they have an [avatar] tag for that film.
