Oyaji

"earth"

- How do we know you're not Fire Nation spies? Kyoshi stayed out of the war so far. And we intend to keep it that way!

Oyaji was the leader of the Kyoshi Island village, appointed to the position over twenty years ago. When the Avatar and his friends first arrived on Kyoshi Island, he was initially averse to the idea of them coming, as Avatar Kyoshi had remained neutral in the war so far. However, he later stood beside Aang and his friends and helped get his people to safety when the Fire Nation attacked.

History
Avatar Aang, Katara and Sokka came to Kyoshi Island. Oyaji, Suki and the other Kyoshi Warriors were initially suspicious of Aang, but believe that he is the Avatar once he Airbends in front of them. He was then seen running to Sokka and the other Kyoshi Warriors, urging them for help as the Fire Nation troops were approaching. He was later shown thanking Aang after he used the Unagi for extinguishing the fires, a result of the fight between Aang and the Kyoshi Warriors and the Fire Nation.

A few months later, he helped Katara and Sokka somewhat in their quest to clear Aang's name. He explained the legend around Avatar Kyoshi's weapons and clothing (and sternly tries to keep the siblings from touching them) and explained the meaning of the picture "Birth of Kyoshi". He also informed Sokka about Suki's departure from Kyoshi Island and the influence he had on her.

His ultimate fate after the war is unknown, although it is likely that he lived happily.
