Zhao

For a time, Admiral Zhao was a villain in the cartoon series Avatar: The Last Airbender.

Origin
Admiral Zhao was once a student of the fire-bending master Jeong Jeong. However, while his master attempted to teach Zhao about restraint, Zhao was only concerned with the power he could wield through fire-bending. He, then, abandoned his teacher, and joined the Fire Nation military.

Goals and Ambitions
Admiral Zhao sought to carry out Firelord Ozai's will, and conquer opposing nations, as well as capture the Avatar. Zhao attempted to dominate the Northern Water Tribe by killing a certain fish in the Spirit Oasis. This fish represented the Moon Spirit.
