Avatar is set in an Asian-influenced world of martial arts and elemental manipulation. The TV show drew on elements from East Asian, South Asian, and Western culture, making it a mixture of what were previously traditionally separate categories of anime and US domestic cartoons.
The movie follows the adventures of the main protagonist Aang and his friends, who must save the world by defeating the Fire Lord and ending the destructive war with the Fire Nation.
List of Avatar: The Last Airbender characters
Aang: is the fun-loving, 112-year-old protagonist of the series, who is biologically 12 years old, but was frozen in an iceberg with his flying bison, Appa, for 100 years. He is the current incarnation of the Avatar, the spirit of the planet in human form. Aang is a reluctant hero, who would prefer adventure over his job as the Avatar and making friends over fighting the Fire Nation.
Katara: is a 14-year-old female Waterbender of the Southern Water Tribe. Katara and her brother, Sokka, discover and free Aang from the iceberg in which he had been trapped. With her brother Sokka, she accompanies Aang on his quest to defeat the Fire Lord, and eventually becomes his Waterbending teacher. In the original unaired pilot episode, Katara's name was Kya; this later is implied to be her mother's name.
Sokka: is a 15-year-old warrior of the Southern Water Tribe. With his sister, Katara, he accompanies Aang on his quest to defeat the Fire Lord. The joker of the group, Sokka describes himself as "meat-loving" and "sarcastic".Unlike his companions, Sokka is not gifted with the power of bending an element, but the series, though it often makes him the victim of comedy at his expense, frequently grants him opportunities to use his ingenuity and weapons, including his trusty boomerang and a sword he forged from a meteorite.
Toph Bei Fong: is a 12-year-old blind Earthbender that appears in the second season of the show. Not long after meeting Aang and his friends, she leaves her wealthy family and comfortable home to join Aang on his quest, with a plan to teach him Earthbending. Though blind, Toph "sees" by feeling the vibrations in the ground through her feet. She is the only Earthbender seen in the show to learn to bend metal and is considered one of the most powerful Earthbenders.
Zuko: is the 16-year-old exiled prince of the Fire Nation and original antagonist of the series. Due to events in Zuko's past, his father, Fire Lord Ozai, deems him a complete failure, and Zuko feels he must capture the Avatar to regain his honor. Over time, Zuko struggles to deal with his anger, self-pity, and familial relationships; meanwhile, he grows sympathetic to the peoples his nation has terrorized. In season three, he defects from the Fire Nation, and joins Aang and the team in order to teach Aang Firebending. At the end of the series, he is crowned ruler of the Fire Nation.
Azula: is the 14-year-old princess of the Fire Nation. She is Zuko's younger sister and one of the major antagonists of the series. Azula is a Firebending prodigy and is one of the few living Firebenders capable of summoning lightning. She has no qualms about bullying and threatening her relatives, reserving any familial loyalty for her father. She is first introduced at the end of season one, although she appears in the background in an earlier episode.
Iroh: is a retired Fire Nation general, known as the Dragon of the West, and Prince Zuko's uncle and mentor. Iroh was the original heir to the Fire Nation throne until his brother usurped the throne after Fire Lord Azulon's death. On the surface, Iroh is a cheerful, kind, and optimistically eccentric old man, but he still remains a competent warrior and a devoted surrogate parent to Zuko. Iroh is a Grand Master of the Order of the White Lotus, a secret society of men from all nations and helps retake Ba Sing Se during the series finale. Unlike most Firebenders, Iroh does not use fury as the source of his strength; instead he uses the original Firebending skills learned from the Dragons. He too is one of the few Firebenders with the rare ability to shoot and redirect lightning. He also has a unique ability to see characters of the spirit world.
