Zuko

Although initially the main antagonist, Zuko has proven to be a complex person rather than a true villain. Initially there is no indication that he will become an anti-villain, but over time he becomes a hero in his own right. Zuko's big heart was, for most of the time, overcome by his desire to return to the Fire Nation; Zuko desperately wanted to regain his right as heir to the throne of the Fire Nation, but above all to regain his father's love, recognition and respect. Zuko believed (or forced himself to believe) that by capturing the Avatar his dreams would come true, which makes Aang his greatest enemy. Zuko believes that a person becomes strong by having to work hard and fight for what they want. He says that he doesn't want to have good luck, because he believes that he can control his own destiny. Even so, all the bad luck he has had in his life has led him to believe that the world is against him. This has turned him into someone with great determination and an iron will that even exceeds his own limits. In the Northern Water Tribe he tells Aang about how his dad doesn't take him seriously since he told him that his sister was born lucky and that he was lucky to be born.

A very kind man and he is like a father to Zuko, he is his uncle, but he loves him like a son, he is a kind and funny person, he loves tea and always accompanies his nephew wherever he goes.
