Avatar Characters

Aang (Zach Tyler Eisen) is the fun-loving, 112-year-old protagonist of the series, 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 duty as the Avatar and making friends over fighting the Fire Nation.

Katara (Mae Whitman) is a powerful, 14-year-old 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. Katara is also one of the only waterbenders that have the ability to bloodbend which allows her to control any person by bending their blood although she is reluctant to use the ability. In the original unaired pilot episode, Katara's name was Kya; this later is stated to be her mother's name.

Sokka (Jack DeSena) 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 does not have any bending ability, 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 (Jessie Flower) is a 12-year-old blind tough 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 (Dante Basco) 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 (Grey DeLisle) is the manipulative 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 casting lightning. She has no qualms about bullying and threatening her relatives or friends, reserving any familial loyalty for her father.

Iroh (Mako in season one and until episode 15 in season 2. Greg Baldwin in season three) 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 powerful 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 is the only shown character to both have the abilities of casting lightning and redirecting lightning attacks.

Appa is a fictional character on the Nickelodeon animated television series Avatar: The Last Airbender. In the show, Appa is the only known living Sky Bison, a race of animals that can naturally fly. He is voiced by Dee Bradley Baker.

Momo is an intelligent and curious winged lemur. Aang found him at the Southern Air Temple soon after starting his quest and decided to keep him as a pet. He often picks fights with other winged and smaller creatures and with Appa over food. Momo can only understand Aang, it was shown in a episode when he asked Momo to get his marble, and in a different episode Katara asked Momo to get some water all he heard was mumbling.
