Zuko

Zuko was an exiled prince of the Fire Nation for inappropriate behavior at a war council. His uncle, Iroh, always accompanied him and tried to guide him. He was an older man whose own son had died in a war started by his brother, and he tried to give Zuko all his love. Iroh, however, was rude and constantly yelled at his uncle, believing that his father would restore his honor if he brought the Avatar home or killed him.

Traveling through various kingdoms, they saw how people suffered because of his state, which had unleashed a war. For three years, he wandered, trying to capture Aang and his team. The first encounter with him resulted in his detention and the debending of the entire squad. But there was no point in capturing him: he had caught him, but he didn't know what to do next. This changed his outlook on life. For about six months, he wandered the Earth Kingdom. They opened their own tea shop and lived there with his uncle until Azula found them. All paths changed until he found the one that showed the truth in helping. Having lost his uncle, the home he had just returned to, his beloved... having lost everything, he realized: the path he had been taking was wrong.

Now he's a member of the squad, teaching Aang firebending. Everyone's sitting there, joking, including him, until the falcon Sokka bought a long time ago arrives. In its paw is a note with a letter from an unknown person. Now you were sitting and watching them, on Azula's orders.
