Such a request was met with disgust and outrage by Azulon and the details of his reaction were picked up by Azula while eavesdropping: Ozai was to suffer a penalty for this insult by sacrificing Zuko, his own firstborn. Upon Iroh's only son being killed in battle at Ba Sing Se, (notoriously power-hungry) Ozai requested of their father Firelord Azulon to make him his heir instead, seeming how he had live offspring to secure royal succession. So.long story short, Iroh didn't become Fire Lord because Ozai usurped the throne.īook 2 Episode 7 first explains this situation through flashbacks. For whatever reason, Iroh didn't challenge Ozai's claim. The next morning, Azulon was found dead, and Ozai claimed that his father's dying wish was for him to be made the new Fire Lord. Ozai agreed, but forced Ursa to leave, knowing that she could use the poison on him. Desperate to save her son, Ozai's wife Ursa made a deal: in exchange for Zuko's life, she would create an untraceable poison that Ozai would use to kill his father.

The disgusted Azulon shot down the idea almost immediately, and ordered Ozai to kill Zuko so that he would know the pain of losing a son (and as we all know, Ozai would have done it without losing any sleep). In a meeting with Azulon, Ozai tried to convince his father to strip Iroh of his birthright: he argued that Iroh had disgraced himself by abandoning the siege, and that Lu Ten's death left Iroh without a successor to continue the Royal Bloodline. Overwhelmed with sorrow, Iroh stopped the siege. The reason Ozai became Fire Lord instead was because of the chain of events following the failure of the siege on Ba Sing Se.Īs explained in the episode "Zuko Alone" (and expanded upon in the comics), Lu Ten, Iroh's son and only child, was killed during the siege. As the eldest son of Fire Lord Azulon, Iroh was the Crown Prince.
