Sokka was a Water Tribe warrior, raised by his grandmother Kanna along with his younger sister Katara in the Southern Water Tribe. Sokka was the son of Kya and Chief Hakoda.
Hakoda left along with all of the other men in his tribe to fight the Fire Nation when Sokka was a young boy. As there were no other teenage boys in the tribe, Sokka was the oldest male in the South Pole, and left leader of the tribe. He assumed responsibility for the tribe, until his sister discovered an Air Nomad named Aang frozen in a block of ice. When he learned that Aang was the Avatar, he was at first skeptical that a child could really save the world. As he and his sister helped Aang on his quest, he began to believe that Aang really was the only hope for peace in the world.
