Previously-announced cast members include Gordon Cormier as Aang, Kiawentiio as Katara, Ian Ousley as Sokka, and Dallas Liu as Prince Zuko, the son of Fire Lord Ozai. Ozai’s drive to conquer and unite the world under firebender rule is a family burden-he believes that it’s his destiny to finish a war started by his ancestors." He demands everyone live up to his impossible standards, especially his teenaged son, Prince Zuko. Netflix describes the live-action Ozai as "the ruthlessly-driven leader of the Fire Nation. In Korra, he played Hiroshi Sato, father of Asami Sato. In the original series, he played Earth Nation soldier General Fong. This is far from Kim's first adventure with Avatar, as he appeared in both the original series and the follow-up, The Legend of Korra. After all, the last time Hollywood tried. If Kim is a series regular, it seems like he'll have a bit more to do. When Netflix announced a new live-action adaptation of Avatar: The Last Airbender in 2018, fans of the beloved animated series were cautiously optimistic.
While Ozai ended up being Aang's final battle in the show, Ozai appeared in visions and shadows early in the series, and didn't actually make a full appearance until the show's third season. "Daniel Dae Kim joins the Avatar: The Last Airbender cast as a series regular," Netflix announced in a follow-up tweet, suggesting that he'll play a bigger role in the live-action series than he did in the animated series. "Netflix's live-action Avatar: The Last Airbender has found its Fire Lord Ozai: Daniel Dae Kim." I have all the power in the world!" the tweet reads, quoting a line from the animated series version of the character as voiced by Mark Hamill.
