Zuko is a firebending master, born as a prince in the Great Fire Nation Royal Family, who held the title of Fire Lord. Initially, Team Avatar's primary enemy, Zuko's early life revolved around trying to capture the long-lost Avatar to end his banishment and regain his honor as Crown Prince of the Fire Nation. Zuko is easily recognized by the distinctive scar on the left side of his face. It was given to him by his father, Fire Lord Ozai, shortly before his banishment as a result of an incident in which he unintentionally disrespected his father by speaking out of turn and refusing to duel him. He was a major figure in the First War and numerous events throughout the Multiverse's history. He joined the allies once he joined Team Avatar.
