During the battle, Ozai manages to slam Aang into a sharp rock, which stabs Aang's scar. Aang releases the seventh chakra and enters the "Avatar state". Though Aang easily overwhelms Ozai, he refuses to kill him. Aang instead uses Energybending to strip Ozai of his Firebending powers. The Order of the White Lotus manage to liberate Ba Sing Se, and Katara manages to defeat Azula and heal Zuko. During his coronation, Fire Lord Zuko promises to aid the world in reconstruction.
