Ep 1. The Avatar State

In the season 2 premiere episode of Avatar: The Last Airbender, titled "The Avatar State," Aang is still reeling from his defeat at the hands of Azula. Azula has taken control of Ba Sing Se and Aang's friends have been captured. Aang is struggling to come to terms with the fact that he lost the battle and that his friends are in danger.

While Aang is feeling defeated, the Fire Nation is celebrating their victory over Ba Sing Se. However, Azula warns her father, Fire Lord Ozai, that the war is not over. She tells him that they need to prepare for the Avatar's return and that they must capture Aang before he becomes too powerful.

Back in the Earth Kingdom, Aang is in the spirit world looking for advice from Avatar Roku. Roku encourages Aang to embrace the Avatar State, a powerful state that all avatars can enter. In this state, the Avatar gains immense power, but risks losing control.

Aang returns to the physical world and decides to enter the Avatar State. As he does so, he gains incredible power and his tattoos begin to glow. However, he quickly loses control and begins to rampage through the Earth Kingdom. Aang's friends try to help him, but they quickly realize that they need to find a way to help him safe again.

Katara decides to visit a spirit oasis in hopes of finding a solution. She is met by the spirit of the moon, who tells her that she must seek out the spirit of the sun in order to find a way to calm Aang down. The spirit of the sun is located in a Fire Nation temple, so Katara and her friends must sneak in without being discovered.

As they make their way to the temple, they encounter a group of Fire Nation soldiers. Sokka devises a clever plan to disguise themselves as members of the Fire Nation in order to get past the guards. Once they reach the temple, they encounter Azula and her team. Aang's friends engage in a fierce battle with Azula, Ty Lee, and Mai.

Meanwhile, Aang is still in the Avatar State and is attacking everything around him. Appa, Aang's loyal sky bison, manages to calm him down and bring him back to his senses.

Aang's friends eventually defeat Azula and her team, but they realize that they need to leave the temple quickly before any more Fire Nation soldiers arrive. They make a narrow escape and return to Aang.

With Aang back to normal, his friends tell him about their journey to the Fire Nation temple and how they were able to find the spirit of the sun. They use the knowledge they gained to help Aang safely enter and exit the Avatar State.
