"Now that you have learned the secrets, and you know about our tribe's existence, we have no choice but to imprison you here forever ... just kidding ... but seriously, don't tell anyone!"
— Sun Warrior chief to Aang and Zuko.[1]
The Sun Warrior chief was the head of the Sun Warrior tribe for over twenty years. His followers appreciated his adherence to traditions. The chief's main goal was to keep his tribe secret and protected. He was aware of how valuable the dragons were to the world, and he wanted to keep them safe.[2] As the leader of the tribe, he had a deep spiritual reverence for fire, as it represents energy and life.
Zuko and Aang later traveled to the city in the summer of 100 ASC, and the chief answered Aang's call for help after Zuko had accidentally trapped them in a slimy substance by touching the tribe's sacred sunstone. With the help of two aardvark sloths, he freed them from their precarious situation, but wanted to punish them severely for taking their ancient relic. Zuko and Aang managed to persuade him not to condemn them and show them the original way of firebending instead. The chief told them that if they wished to learn the true way, they would need to pass the judgment of the masters, Ran and Shaw, and proceeded to lead the duo to the Eternal Flame. He presented them each with a part of the ancient flame before sending them on their way to the cave of the masters. The chief also warned both of them that the masters may be angry to see them because Zuko's ancestors hunted the dragons for glory and Aang neglected his duties as the Avatar by running away. Once Zuko and Aang arrived at the base of the master's cave, he conducted a ceremony to bring them out. When the masters presented themselves, he and the rest of the Sun Warriors bowed down in respect.
He took Sun Warrior philosophy very seriously, however, after Aang and Zuko were deemed worthy by the masters; he was shown to be less stern with them and even made an attempt to joke, by saying that he would have to imprison them forever now that they had knowledge of the dragons and their tribe. This statement worried the duo until the chief revealed he was only joking, although he requested them to keep silent about the tribe's existence.[1]
The Sun Warrior chief was a serious man, being very protective of the firebending origin. He was a kind and informative person, helping Aang and Zuko when the latter visited the Sun Warrior ruins. Even though he was very serious, the chief also had a lighter side and a sense of humor, shown when he messed with Aang and Zuko's heads by telling them that they were to be imprisoned at the ruins forever after learning the true meaning of firebending.[1]
