Kuvira

Kuvira is a master metalbender who served as a political and military leader of the Earth Kingdom and the Earth Empire between 171 and 174 AG. Before her rise to power, she was a prominent member of the Metal Clan, serving as both the captain of the guard in Zaofu and part of Suyin Beifong's dance troupe. Following the outbreak of anarchy in the Earth Kingdom upon Earth Queen Hou-Ting's assassination, Kuvira left the Metal Clan and earned the trust of the world leaders by stabilizing Ba Sing Se and was appointed as the nation's provisional leader. For the next three years, she subsequently set out to reunite the rest of the kingdom with her army, which earned her the title of "Great Uniter". In her pursuit of order, Kuvira offered to protect the nation's states from bandits in exchange for their loyalty. During Prince Wu's coronation, Kuvira denounced the authority of the Earth King and dissolved the Earth Kingdom in favor of an "Earth Empire" under her leadership.
