Sokka

Sokka is a teenage Water Tribe warrior. Raised by his grandmother Kanna along with his younger sister Katara in the Southern Water Tribe, Sokka is the son of Chief Hakoda, who left along with all of the other men in his tribe to fight the Fire Nation. As a result, Sokka was the oldest male in the South Pole. He assumed responsibility for the tribe until his sister discovered an Air Nomad named Aang frozen in a block of ice. When he learns that Aang is the Avatar, he is at first skeptical that a child could really save the world. As he and his sister help Aang on his quest, he begins to believe that Aang really is the only hope for peace in the world.
