Zuko is easily recognized by the characteristic burn scar on the left side of his face given to him by his abusive father, Fire Lord Ozai shortly before his banishment. On his journey to capture the Avatar, he is assisted by his uncle Iroh in Firebending training.
Prince Zuko is played by Dev Patel in Avatar the Last Airbender Movie, a 16-year-old prince who travels with his uncle and tries to capture the Avatar in order to regain his honor and position as heir to the Fire Nation throne.
