Zuko (Avatar: The Last Airbender)

Zuko is a character from the Avatar: The Last Airbender TV series. He was a firebender and prince of the Fire Nation who was banished from his country, unable to return until he found the long-lost Avatar.

While Zuko was an antagonist at first, trying to kidnap Aang, later he became friends with Aang and company, and taught Aang how to firebend.
