Sokka's life underwent a significant transformation after his father left to fight in the Hundred Year War. He idolized his father and aspired to become a valiant warrior like him. His father's departure left him deeply saddened, but it also instilled in him a sense of responsibility. He took on the role of protector, especially towards his sister Katara, and became somewhat overprotective at times. Sokka's primary weapon, a metal boomerang, was a gift from his father and became his most prized possession. He also developed a strong bond with Aang, whom he and Katara discovered in the ice, and this new 'family' became a source of strength and support for him. Sokka's experiences and relationships shaped him into a resilient and loyal individual, always ready to defend his loved ones and his tribe.
