Sokka is a fictional character in Nickelodeon's animated television series Avatar: The Last Airbender and its sequel series The Legend of Korra. The character, created by Michael Dante DiMartino and Bryan Konietzko, is voiced by Jack DeSena in the original series and by Chris Hardwick in the sequel series. He is a warrior of the Water Tribe and the son of Chief Hakoda and Kya. In the live-action film adaptation, he is portrayed by Jackson Rathbone, while in the forthcoming live-action television series adaptation, he will be portrayed by Ian Ousley. In the original series, fifteen-year-old Sokka is a warrior of the Southern Water Tribe, a nation where some people are able to telekinetically manipulate, or "bend", water. He, along with his younger sister Katara, discovers an Airbender named Aang, the long-lost Avatar, and accompanies him to defeat the imperialistic Fire Nation and bring peace to the war-torn nations. Unlike his companions, Sokka is a non-bender, but as the show progresses he masters swordplay and proves himself to be a worthy strategist. Being a non-bender, Sokka uses different weapons such as his boomerang and machete; and eventually a jian sword to combat enemies.
