Aang is a fictional character and the main protagonist for Nickelodeon's animated television series Avatar: The Last Airbender. The character was created by Michael Dante DiMartino and Bryan Konietzko and is voiced by Zach Tyler Eisen. Aang, being the central characer for the program, has appeared in every episode of the show, including the pilot episode that has never been aired. In addition to the series, Aang has also appeared in a variety of other media, such as trading cards, video games, T-shirts, and web comics.

In the show, twelve-year-old Aang is the last surviving Airbender, a monk of the Air Nomads' Southern Air Temple, and a supercentenarian at the incarnation age of 112. However, one century of his lifetime, which occurred before the events of the first episode in the show, was spent frozen is suspended animation, making his biological age only twelve. He is revealed in the second episode as the current incarnation of the Avatar, the spirit of the planet manifested in human form. Aang, as the Avatar in the show, controls the elements and is tasked with keeping the Four Nations at peace. The show follows Aang's journeys to complete this task, including many battles and disputes that he must settle either along or with others.

In the show, Aang has shown fun, yet very conservative and caring traditions. Most of these traits, such as vegetarianism, are based off of Buddhism and Taoism tradition. In addition, Aang is claimed to be the series' reluctant hero, showing hesitation when joining new friends Katara and Sokka on a quest to master the elements and save their world from the war-hungry imperialist Fire Nation. His fun, lighthearted personality has been accepted well amongst critics as well as the show's audience itself. As it can probably be deducted, the creators intended Aang to mainly use his wits to defeat enemies and be a kind of trickster hero.
