Elsewhere, Jet repeatedly tries and fails to gather evidence that Zuko and Iroh are firebenders, and his allies in the Freedom Fighters begin to believe he is losing his steel.
While at Xin Fu's earthbending tournament, Team Avatar witnesses a display of powerful earthbending by a young blind girl named , who Aang recognizes as the girl from his vision in the spirit swamp. And Iroh bonds with an unlikely individual. His last attempt, challenging Zuko to a sword fight, ends in his own arrest and being brainwashed by the Dai Li into believing there is no war in the city.

The Earth Kingdom remains and fights a hopeless war against the Fire Nation. It is here that the village's last remaining waterbender Katara and her warrior brother Sokka rescue a strange 12-year-old boy named Aang who has been suspended in hibernation in an iceberg. As Zuko defends the family against abusive Earth Kingdom soldiers, he reveals his identity as the Fire Prince at the battle's end, and the boy, his family, and the townspeople reject him because of it. Upon hearing that Appa was muzzled, Aang becomes so angry and upset that he enters the Avatar State, almost wiping out the sandbenders, but is eventually calmed by Katara. Almost at the point of true enlightenment, Aang sees a vision of impending danger for Katara and retreats from disattachment, instantly deciding to return to her and protect her at all costs, even though Guru Pathik warns that this may leave Aang's final chakra inaccessible, compromising his ability to safely and reliably access the Avatar State at all. Aang nearly destroys the base in anger but is then told by Avatar Roku that if he is killed in his Avatar State the Avatar Spirit will cease to exist, bringing to an end the cycle of reincarnation which preserves the Avatar as a force for balance in the world.
That bender is the Avatar. Their journey leads to , the capital of the , where they uncover great internal government corruption. Last Episode, 19 July 2008: Aang defeats the Fire Lord by bending the elements within the Fire Lord and removing his fire bending abilities. He later unwillingly enters a fight with a Boarcupine, and wins but is badly wounded. They are assigned a liaison, an uncomfortably cheerful young woman named Joo Dee, who indirectly makes it clear to them that any mention of the war is forbidden within the walls of the city, one of many disturbing rules they begin to encounter that are enforced by the Dai Li, the secret police of Ba Sing Se, and their corrupt leader, Long Feng, who appears to know something about Appa. They are reunited and attacked by a swamp monster who turns out to be a wise man from a tribe of swamp waterbenders who use the moisture inside the swamp's plants to manipulate the plants and hide their identities. In the United Kingdom, only the season boxset was released without being released in four volumes first.
They travel to a facility located at the bottom of Lake Laogai, in the hopes of finding Appa. Long Feng is tricked into a deal with Azula where he will exchange Aang for assistance in regaining control of the Dai Li and consolidating their power over the Earth Kingdom throne, which will then act as a proxy government for the Fire Kingdom. She runs away from home and joins Aang. Toph blames Appa for the chase and the group realize that she is correct: they are being tracked because Appa is shedding. The group finally makes it to Ba Sing Se only to find the Fire Nation is about to send a gigantic drill to penetrate the titanic outermost walls of the capital region, which have protected the people within, including the Earth Kingdom leadership, form more than a century of Fire Nation assault.
In the battle that follows, Aang realizes that he must let go of Katara in order fulfill his destiny, and meditates into the Avatar state, but Azula hits him with lightning while in the Avatar State, striking him in exactly the location of the Chakra the Guru had cautioned him about, and putting the Avatar near the brink of death. However, while he possesses ten years of experience and in-depth knowledge, starting afresh with neither sponsors nor a team in a game that has changed over the years presents numerous challenges. The Air Nomads were destroyed, the Air Temples ravished, and all airbender monks eradicated. The villagers blame Avatar Kyoshi, one of Aang's previous incarnations in the avatar cycle of reincarnation, for killing their leader, Chin the Great. Aang reveals his identity and is arrested and put on trial for Kyoshi's supposed crimes. But General Fong, inspired by Aang's battle-determining actions during the Siege of the North, suggests that Aang defeat the Fire Lord and end the war immediately by triggering the Avatar State. Elsewhere, Zuko discovers that Aang is in the city and sets out in the disguise of the Blue Spirit to find him, and believes he has hit on a winning strategy when he discovers the imprisoned Appa.
Uncle and nephew manage to escape but are forced to become outcasts because of Iroh's efforts in saving of the Moon Spirit at the North Pole are viewed as a treachery by the Fire Nation, and Zuko's failure to capture the Avatar has made him a target as well. Launching into an offensive, Iroh delays Azula, Zuko, and the Dai Li long enough to allow Katara to escape along with the gravely injured Aang, and then surrenders, being taken prisoner as a traitor to the Fire Nation. In each generation, only one bender is solely capable of controlling all four elements. After a long trek and much hardship in the desert, tracks down the sandbenders who stole Appa, and learns that Appa was traded to a merchant and is likely in Ba Sing Se, the imposing capital city of the Earth Kingdom. Like , the creative forces behind the show have tapped into that basic, generation spanning storytelling that will live long after the series' youngest fans are old and bitter. Zuko also arrives determined to claim his prize.
Now Katara and Sokka must safeguard the child Avatar in his journey to master all four elements and save the world from the Fire Nation. Inside, Sokka discovers a crucial weakness to the Fire Nation that could end the war: the date of the upcoming solar eclipse which will temporarily prevent the bender of the Fire Nation from firebending for its duration. Katara uses a vial of spirit water earlier given to her from the pool of the spirits after the Siege of the North in order to save Aang as the team, with a deposed Earth King Kuei in tow, flees from Ba Sing Se, now in the hands of the Fire Nation after a century of resistance. Aang attempts to trade him for King Bumi, but Princess , calls off the trade; she is now backed up by her friends Mai and Ty Lee, recently re-recruited because each is a skilled fighter. Aang is pardoned after he defeats a group of Fire Nation soldiers that attack the village, and the town changes the anti-Avatar celebration to a pro-Avatar celebration.
