* Toph Bei Fong (Jessie Flower) is a 12 year old blind, tough Earthbender who 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 and a plan to teach him Earthbending. Though blind, Toph "sees" by feeling vibrations in the ground through her feet. She is the only Earthbender 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 complex familial relationships. Over the course of the series he grows sympathetic to the people his nation has terrorized. He takes on the identity of "the blue spirit" at the end of season one and beginning of season two. In season three, he defects from the Fire Nation and joins the Avatar 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 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.
