Avatar: The Last Airbender (Avatar: The Legend of Aang in some regions) is an American animated television series that aired for three seasons (referred to as "books" in each episode's title card) on Nickelodeon from 2005 to 2008. Avatar: The Last Airbender is set in an Asiatic-like world in which some people are able to manipulate the classical elements by use of psychokinetic variants of Chinese martial arts, known as "bending". The show combines the styles of anime and American cartoons, and relies on the imagery of various East Asian, Inuit, Southeast Asian, South Asian, and New World societies. Therefore, whether or not the series can be considered as an anime work is often discussed.
