Aang recovers from a long coma to find his friends and allies disguised as soldiers on a Fire Nation ship, preparing invasion of the Fire Nation. Despite receiving credit for the Avatar's apparent death, Zuko regrets his role therein. Although the invasion meets great success at first, Aang and his friends are unable to find Ozai and are forced to retreat with many of their allies captured. At the same time, having learned of his father's intention to destroy the Earth Kingdom at the time of Sozin's Comet, Zuko leaves the palace to teach Aang Firebending. As the comet approaches, Aang becomes reluctant to kill Ozai, and goes alone to consult his predecessors' spirits. Katara and the others unsuccessfully search for Aang, and find the newly escaped Iroh, joined by the other members of a secret society called the Order of the White Lotus: Bumi, Master Pakku, Jeong-Jeong, and Master Piandao (a master swordsman who taught Sokka). Together, the Order of the White Lotus liberates Ba Sing Se. Sokka, Toph, and Kyoshi Warrior Suki hinder the Fire Nation's airships, while Zuko and Katara prevent Azula from becoming the new Fire Lord. As Sozin's Comet arrives, Aang confronts Ozai, but finds himself in a losing battle until Ozai mistakenly re-establishes Aang's connection to the Avatar State. Thus enabled, Aang strips Ozai of his firebending powers, instead of killing him. Soon after, Zuko is crowned the new Fire Lord and initiates an armistice. The series ends in a meeting of all the protagonists at Ba Sing Se in Iroh's tea shop, the Jasmine Dragon, where Aang and Katara hug and then kiss beneath the sunset. The camera then zooms up and into the sunset, displaying the words "The End" with their Chinese counterparts above them.
