Avatar: The Last Airbender (Avatar: The Legend of Aang in some regions) is an American animated television series that aired for three seasons on Nickelodeon. The series began in February 2005 and concluded in July 2008 with a two-hour episode titled Sozin's Comet. Avatar: The Last Airbender is set in an Asiatic-like world in which some people can manipulate the classical elements with psychokinetic variants of the Chinese martial arts known as "bending". The series is presented in a style that combines anime with American cartoons and relies on the imagery of East/South Asian, Inuit, and New World societies. It follows the protagonist, 12-year-old Aang and his friends, who must bring peace and unity to the world by ending the Fire Lord's war with three nations.
The series was commercially successful and was acclaimed by audiences and critics who praised its art direction, humor, cultural references, characters, and themes. It was nominated for—and won—Annie Awards, Genesis Awards, a Primetime Emmy Award, and a Peabody Award. The first season's success prompted Nickelodeon to order a second and third season. Merchandising for the series consisted of action figures, a trading card game, three video games, stuffed animals distributed by Paramount Parks, and two Lego sets. An art book was published in June 2010. The complete series was released on Blu-ray on June 5, 2018 for the 10th anniversary of season 3's finale.
The series inspired a critically panned but financially successful live-action film, The Last Airbender, directed by M. Night Shyamalan and considered one of the worst movies ever made. An animated sequel series, The Legend of Korra, aired from 2012 to 2014. A new live-action remake of the series by its original creators produced for Netflix was announced in September 2018.
