Haro was a Dothraki khal who lived during the Century of Blood. He was one of the four khals that fought in the Field of Crows.
Khal Haro joined forces with Khals Qano, Loso, and Zhako to fight against High King Mazor Alexi, who had united all of the Sarnori lesser kings to defend their homeland against the Dothraki hordes. The battle took place halfway between Sarnath and the ruins of Kasath. The Sarnori chariots smashed the center of the Dothraki horde. Haro was trampled and died, while his Dothraki fled. However, the escape was a trap and Alexi and his forces were attacked on all sides and destroyed.
