Zuko

""You rise with the moon. I rise...with the sun.""

- ~Zuko to Katara

For a time, Zuko was recognized as the main villain in the cartoon series Avatar: The Last Airbender.

Origin
Zuko was the only son of Firelord Ozai, although, he was never treated like much of a son. From the beginning, Ozai seemed to favor Azula over Zuko for some unknown reason. When Zuko was old enough, his father invited him to take part of his military operations. However, Ozai became infuriated when Zuko protested an operation that would've claimed the lives of Fire Nation soldiers. Ozai challenged his son to Agni Kai, a special Fire Nation duel, and severely burned Zuko's left eye. Then, Ozai banished him from the Fire Nation, and charged him with capturing the Avatar. Zuko also has an alter-ego known as the Blue Spirit.

Powers and Abilities
Zuko is a very skilled firebender who controls his fire quite well. When challenged to Agni Kai by Admiral Zhao, Zuko was able to beat him fairly easily, thanks to all his training. Zuko's fire was fueled by rage and anger, which he had plenty of. When Azula threatened his life, and Iroh's Zuko attempted to learn how to shoot lightning. Unfortunately, this was a skill he was unable to master until he learned to manage his inner turmoil.
