Sokka came from the Southern Water Tribe. A warrior-to-be, 15-year-old Sokka was a very physical person. He was protective of his younger sister, Katara, and treasured the boomerang given to him by his father, Hakoda.
When his father left with the other men of the tribe to fight in the War, Sokka was put under his Gran Gran's care and became his tribe's last defense, although there were little kids who were about seven–nine years old who assumed the role of soldiers. He took the task very seriously and even built a number of snow watchtowers around the village. Although Sokka had the spirit of a soldier and the courage to stand up to any enemy, at the beginning of the series he lacked the skills and techniques that would make him a formidable opponent. That wouldn't stop him from trying though, especially if his friends needed help.
