3rd season Azula's rigged 3d model. Model created and rigged in Blender 3d version 3.0.0 , rendered in evee. In the early episodes of this season, Azula bonds with her brother and friends after their victorious return to the Fire Nation with Iroh as a prisoner. However, Azula lies to Ozai by claiming that Zuko killed Aang, as she has a hunch that Aang survived and knows that all the blame would now fall on Zuko if this were true. During the two-part episode The Day of Black Sun, Aang assembles an elite invasion force and attacks the capital, taking advantage of a solar eclipse that renders the firebenders powerless. Having been warned by Azula, Ozai is evacuated to an underground bunker prior to the invasion. Azula and her Dai Li agents stall Aang and his friends Sokka and Toph from finding Ozai before the eclipse, which lasts only eight minutes, allowing the firebenders to retaliate with full force once they regain their bending, causing the invasion to fail. However, Zuko defects to Team Avatar after confronting Ozai during the eclipse.[11]

Later, Azula, accompanied by Mai and Ty Lee, visits The Boiling Rock, the top security Fire Nation prison where Zuko has been captured in an attempt to infiltrate the prison and rescue the captured forces of the failed invasion. However, Zuko, Sokka, Suki (leader of the Kyoshi Warriors, who had been captured in the aftermath of their battle with Azula) and Sokka's father Hakoda manage to escape. Mai betrays Azula by aiding the group's escape, proclaiming that she is doing so out of her love for Zuko. Enraged, Azula attempts to attack Mai but is stopped by Ty Lee, who renders her incapable of bending by blocking her chi (the energy within one which one would use for bending). After having Mai and Ty Lee imprisoned for betraying her,[12] Azula leads a platoon to the Western Air Temple, where she duels with Zuko. The fight ends in a draw, with Azula narrowly escaping death after falling from one of the airships while the protagonists manage to flee.[13]

In the finale, Ozai leaves Azula behind in the Fire Nation as he sets out to conquer the world, naming her as his successor to the Fire Lord position. Soon afterward, Azula sinks into psychosis, hallucinates about her long-lost mother, and deposes nearly all of her servants and advisers. Before she is crowned as Fire Lord, Zuko and Katara interrupt the ceremony, whereupon Azula challenges Zuko to single combat in an Agni Kai. However, Azula's attacks, while powerful, are wild and emotional while Zuko's are calm and disciplined; and when his attacks begin to overpower her, she sends a bolt of lightning toward Katara, but ends up striking down Zuko, who attempts to redirect it.[14] She is ultimately defeated by Katara who takes her captive via waterbending, causing Azula to have a complete nervous breakdown.[15]
