The final season focuses once again on Avatar Aang, now seeking to learn Firebending, and his friends Katara, Sokka, and Toph, who must defeat the tyrannical Fire Lord Ozai before the arrival of Sozin's Comet. Concurrently, it also follows Prince Zuko, who is finally welcomed back into the Fire Nation after betraying his uncle Iroh and helping his sister Azula conquer Ba Sing Se in Book Two.
