Avatar: The Untold Legend
The Man Who Challanged the Avatar
Hao had a light brown skin, indicating a Water Tribe nationality, and he wore a black robe, much like Liu.
Most of Hao’s backstory is unknown, as the only time he was seen by The Six Benders was when he challanged the Avatar and terrorised the spectators, where he was shortly killed by Avatar Kyoshi. His name was also mentioned in the meeting between Liu and another robed man just outside Chin Village, where they found his death “a pity”.
Hao was a powerful waterbender, capable of controlling groundwater to use it to flood an arena, and some survivors of the attack claim he opened the arena’s ceiling with earthbending, but Avatar Kyoshi was certain that he was just a normal waterbender.
