Ozai

""You're weak, just like the rest of your people! They did not deserve to exist in this world — in my world! Prepare to join them. Prepare to die!""

- ~Ozai to Avatar Aang

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

Origin
Ozai seemed like a normal man living in the Fire Nation, but he certainly had a lust for power. When his nephew, Lu Ten, was killed in battle he asked his father, Azulon to relinquish the title of Firelord to him. Outraged by this request, Azulon 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 King". To do this, he attempted to use Sozin's comet to wipe out any remaining forces that opposed him.

Defeat

As Ozai started his rampage, he was intercepted by Aang, who shot down his warship. Ozai evacuated the ship and launched himself onto a pillar opposite aang. the two faced off in an epic clash. Ozai ultimately gained the advantage due to Aang's reluctance to kill Ozai. As Ozai knocked aang against a rock, the scar that kept aang from accessing the avatar state was filled by a rock, freeing the chakra. Aang, now in the avatar state, grabbed a stunned Ozai by the beard and proceeded to mercilessly pummel him. Ultimately aang refused to kill Ozai, and instead stripped him of his power with Energybending. Ozai was then thrown into a prison cell to rot. He also became a broken man. He deeply regrets banishing Zuko because Zuko became a better man and help the Aang defeat him.
