Sozin's Comet: The Final Battle
That night, Aang sleepwalks to a forest not to be found in the morning. After the group fails to locate him, Zuko takes them to June, a tracker who might be able to locate Aang, using his smell. Meanwhile, Fire Lord Ozai proclaims himself to be ruler of the world, under the title "Phoenix King", and declares Azula to be the new Fire Lord, setting off to burn the world and rebuild it under his New Order.
