The show's story centers around Aang, the biologically-12 ( chronologically 112) year-old incarnation of the current Avatar, and the eponymous Last Airbender. The Avatar's role is to serve as a peacekeeper and protector for all four nations (as well as bridging and balancing the physical and spiritual worlds). Each nation has developed a spiritual art form to manipulate ("bend") their namesake element, but only the Avatar - one person reincarnated periodically into each race - is capable of mastering all four elements. It is the first series in an eponymous franchise which takes place in a Constructed World divided into four nations: the Water Tribes, the Earth Kingdom, the Fire Nation, and the Air Nomads.

Avatar: The Last Airbender is a Nicktoon that ran from 2005-2008 on Nickelodeon.
