The Senlin Village leader was the head of a village that was terrorized by an angry spirit named Hei Bai. Though he entrusted AvatarAang to try and calm Hei Bai, he was slightly skeptical of the young Avatar's ability to do so.[2]
The village leader met Aang and his friends when an old wanderer guided them into town, hoping that the Avatar would be able to resolve the village's crisis. Upon learning that Aang was the Avatar, he expressed his joy to be in the young Avatar's presence, but also doubted Aang's ability to help the village. He was fearful of Hei Bai's rampage, but was even more frightened at the prospect of the approaching winter solstice, in which the natural world and the Spirit World would grow closer together. The leader was uncertain of what the spirit might do when the line between both worlds was blurred completely.
The village leader locked himself in the main building with the other villagers while Aang tried to calm Hei Bai during the night. Upon noticing Aang's failure to do so, and his running behind the spirit, the leader simply remarked that "the Avatar's methods [were] unusual". Despite being strongly warned of the dangers, Sokka rushed out to help Aang. When Katara moved to leave as well, the village leader held her back. Once Aang managed to calm down the enraged Forest Spirit, the leader wanted to repay them, and offered them money and supplies to help them prepare for their journey to Crescent Island.[1]
After Team Avatar left his village, PrinceZuko arrived and pushed the leader down in order to inquire about the Avatar's whereabouts.[3]
