Zuko is the Crown Prince of the Fire Nation and a skilled firebender, meaning he has the ability to create and control fire. He is the eldest child of Fire Lord Ozai and the older brother of Princess Azula. Before the events of the series, Zuko is banished from the Fire Nation by his father and told he must capture the Avatar, a unique spiritually powerful individual who could threaten Ozai's plan for global conquest, in order to restore his honor and right to the throne. Zuko is accompanied and advised in his search by his uncle Iroh. ## Personality Book One: Water In the first season, Zuko is introduced as the main antagonist, the exiled son of Fire Lord Ozai who is attempting to capture Avatar Aang in hopes of reclaiming his honor. Throughout the season he pursues the Avatar, at times both helped and hindered by his uncle, Iroh. Zuko competes in his quest against Zhao, an ambitious Fire Nation admiral who is also attempting to capture the Avatar for political gain. When Zhao captures Aang, Zuko disguises himself as "The Blue Spirit" and rescues Aang from Zhao's fortress to prevent him from accomplishing his goal. Later, Zuko escapes an assassination attempt plotted by Zhao. During the invasion of the Northern Water Tribe, Zuko captures Aang, but both nearly die in a snowstorm before they are rescued by Aang's friends, Katara and Sokka. Zuko encounters Zhao and attacks him, but Aang, in the Avatar State, abducts Zhao before the fight is concluded. Zuko attempts to save Zhao from Aang, but Zhao is too proud to accept Zuko's help. Zuko survives the battle with help from Iroh, who betrayed Zhao to protect the ocean and moon spirits. In retaliation for Iroh's betrayal and Zuko's failure to capture the Avatar, Ozai assigns Zuko's psychopathic younger sister Azula to capture Zuko and Iroh. Book Two: Earth In the second season, Zuko and Iroh travel the Earth Kingdom as impoverished refugees, pursued by Azula. After briefly quarreling and parting ways with Iroh, Zuko reunites with his uncle against Azula. After Azula wounds Iroh, Zuko nurses Iroh back to health and Iroh teaches Zuko the rare firebending technique of redirecting lightning. Zuko and Iroh travel to the walled city of Ba Sing Se and find employment at a tea shop in the slums. Zuko reluctantly adapts to his new life until he learns of Aang's presence in Ba Sing Se and attempts to steal Aang's pet bison Appa. However, Iroh convinces Zuko to abandon his quest and let Appa go. Azula infiltrates the city to stage a coup and arranges a trap for Zuko and Iroh. Imprisoned together with Aang's friend Katara, Zuko is rescued alongside her by Aang and Iroh, only to be convinced by Azula to betray Iroh, Katara and the Avatar and finally regain his honor. In the resulting fight, Aang is mortally wounded, though later revived by Katara, and Iroh is arrested for helping Aang, Katara escapes from the conquered city with Aang. Book Three: Fire In the third season, Zuko returns to his country a hero thanks to Azula crediting him with killing the Avatar. Zuko suspects that Aang survived and hires an assassin to ensure Aang's death to cover up Azula's lie. He resumes his romantic relationship with his childhood friend Mai, but continues to feel guilty and uncertain of his decisions. After he learns that his mother's grandfather was Avatar Roku, Aang's predecessor, as well as Azula and Ozai's plan to burn the Earth Kingdom to the ground, Zuko decides to turn his back on the Fire Nation and help Aang overthrow Ozai. He confronts his father about his cruel treatment and the Fire Nation's destructive effect on the world, before leaving to join Aang. Although they initially reject him, Aang and his companions grow to accept Zuko as a member of the group after he proves his loyalty to them. He trains Aang in firebending, and the two journey together to meet the last dragons, from whom they learn that firebending can be powered by the energy of life, rather than rage. When Zuko is finally reunited with Iroh in the series finale, he tearfully apologizes for his mistakes and gets his uncle's forgiveness. Refusing the throne himself, Iroh suggests that Zuko become the next Fire Lord, citing Zuko's "unquestionable honor." Arriving at the Fire Nation capital with Katara, Zuko duels Azula for the throne. When Azula faces defeat, she forces Zuko to place himself in the path of a lightning bolt aimed at Katara, wounding him. Katara defeats Azula and heals Zuko. After Aang defeats Ozai and wins the war, Zuko becomes the new Fire Lord, promising world order and harmony with the aid of the Avatar.

Zuko is a complex character who demonstrates a number of contradictory traits, beliefs, and behaviors. As Fire Nation royalty, he has a superiority complex and considers many people to be inferior to him. Though at the same time he has a great sense of justice and refuses to view people as expendable. Zuko felt that he did not need luck so he could be the master of his own fate; but he also believed that he was "lucky to be born" in contrast to Azula who was "born lucky", and that his bad luck had turned the whole world against him. In "Avatar: The Lost Adventures," it was revealed that he studied under Master Piandao, his uncle's colleague and Sokka's master sword fighting instructor. Zuko has also demonstrated an ability in stealth and unarmed combat, as when able to infiltrate a Fire Nation fortress, the Northern Water Tribe's city, and the Dai Li's base in the Earth Kingdom without detection
