Ozai

Firelord Ozai is the main villain in the cartoon series Avatar: The Last Airbender.

Origin
Ozai seemed like a normal man living&#160; in the Fire Nation, but he certainly had a lust for power. When his nephew, Lu Ten, was killed in battle he asked Sozin to relinquish the title of Firelord to him. Outraged by this request, Sozin ordered Ozai to kill his son, Zuko. At first, Ozai was willing to comply with this request, however, his wife, Ursa managed to save her son's life by taking his place. However, instead of being killed, she was banished.

Goals and Ambitions
Ozai's main goal is to conquer all the nations and rule over them under the title of "The Phoenix". To do this, he attempted to use Sozin's comet to wipe out any remaining forces that opposed him.
