After the last challenge, Aang is forced to figure out the King's name, and based on the nature of the challenges, he realizes that the King is his old friend Bumi. The King suspects that Aang is the Avatar and puts him through three deadly challenges to test his skills. Put in front of the crazy King of the city, the gang is given a feast. The trio gives the chutes a try but runs into trouble after it destroys a cabbage merchant's cart. There, Aang shows Katara and Sokka the Omashu chute mail delivery system, which he and his friend Bumi used to ride for fun a hundred years ago. The next stop on the group's trip around the world is the Earth Kingdom city of Omashu. Meanwhile, Zuko catches up to them and begins to burn the village until the group leaves the village, knowing that Zuko will follow them. While there, Sokka is trained by the Kyoshi Warrior Suki who manages to change his sexist attitude, and Aang lets the village's reverence of him go to his head. Aang is able to convince them to trust him, for Kyoshi was a past Avatar and he is the current Avatar. Before they are able to leave, the gang are captured by a group of female warriors who live on the island. Looking for a short break from their travels, Aang brings the gang to Kyoshi Island, where he seeks to ride the Elephant Koi, a large fish who inhabits the surrounding waters. Zhao tries to kill Zuko after Zuko turns his back on Zhou, though Iroh stops the attack in time. Zuko then challenges Zhao to a duel over the right to track the Avatar, which Zuko wins. There, he and his uncle run into Commander Zhao, who manages to learn that the Avatar has been found. Meanwhile, because his ship was damaged by Aang in the previous episode, Zuko needs to stop at a docking area to have it repaired. When he learns the truth about how the Fire Nation had raided his home, Aang becomes angry and enters the Avatar State. At the temple, Aang finds a flying lemur, whom he names Momo. He tells stories of his old mentor, Monk Gyatso, as well as sports and games that Airbenders used to play. Katara and Sokka decide to travel with Aang to the North Pole so that Aang can learn Waterbending.Дue to an interest in reliving his old memories, Aang suggests a visit to the Southern Air Temple. Aang and his friends manage to defeat Zuko and his subordinates. Katara and Sokka take the flying bison Appa to go after Aang.

Aboard Zuko's ship, Aang is at Zuko's mercy, but he eventually manages to maneuver away from the guards and to battle Zuko. Aang returns into the village, after previously being banished, to surrender himself to Zuko as long as he agrees to leave the village alone. When Zuko locates the Southern Water Tribe village where Aang had been, he demands the Avatar be surrendered to him. They accidentally set off an explosion in the ship, which alerts Zuko to the village. While exploring an abandoned Fire Nation ship, Katara tells Aang about the war that had been going on for the past hundred years. Meanwhile, Zuko, the banished Prince of the Fire Nation, is patrolling the seas in search of the Avatar. The Avatar is reincarnated generation after generation and would be the only one who could prevent the Fire Nation from conquering all the nations, which is the reason why the Fire Nation started the war. Later, he reluctantly reveals that he is also the Avatar, the only person with the power to manipulate all four elements. After freeing him, they discover that Aang is an Airbender, a race of people assumed to have died out a hundred years before. While fishing, Sokka and Katara discover Aang and his flying bison, Appa, icebound floating on the sea.
