Avatar: The Last Airbender

The series is set in a largely Asian-inspired world in which some people can telekinetically manipulate one of the four elements—water, earth, fire or air—through practices known as "bending", inspired by Chinese martial arts. The only individual who can bend all four elements, the "Avatar", is responsible for maintaining harmony among the world's four nations, and serves as the link between the physical and spirit worlds. The series follows the journey of twelve-year-old Aang, the current Avatar and last survivor of his nation, the Air Nomads, along with his friends Katara, Sokka, and Toph, as they strive to end the Fire Nation's war against the other nations and defeat Fire Lord Ozai before he conquers the world. The series also follows Zuko—the exiled prince of the Fire Nation, seeking to restore his lost honor by capturing Aang, accompanied by his uncle Iroh—and later, his sister Azula. Avatar: The Last Airbender is presented and animated in a style that combines Japanese anime influences with those of American cartoons and relies on the imagery of primarily Chinese culture, with various other influences from different East Asian, Southeast Asian, South Asian, North Asian, and indigenous American cultures.

Avatar: The Last Airbender was a ratings success and received widespread acclaim from critics and audiences, with high praise given to its characters, cultural references, art direction, voice acting, soundtrack, humor, ending, and thematic content. The series explores themes rarely touched on in youth entertainment, such as war, genocide, sexism, gender roles, imperialism, totalitarianism, class warfare, political corruption, indoctrination, animal cruelty, fate, and free choice. It won five Annie Awards, a Genesis Award, a Primetime Emmy Award, a Kids' Choice Award, and a Peabody Award. Since its release, the show has been regarded by critics as one of the most acclaimed series of the 21st century, and one of the greatest animated television series of all time. It is also considered Nickelodeon's magnum opus.

The extended franchise includes an ongoing comics series, a prequel novel series, two animated sequel series, a live-action film, and a Netflix live-action adaptation series. The complete series was released on Blu-ray in June 2018 in honor of the tenth anniversary of its finale and was made available to stream on Netflix in the United States and Canada in May 2020, on Paramount+ in June 2020, and on Amazon Prime Video in January 2021. A direct animated sequel film was scheduled to release theatrically, but was instead released on Paramount+ in July 2026.
