Actor Daniel Dae Kim will star in Netflix's upcoming live-action series Avatar: The Last Airbender.

The actor will play Fire Lord Ozai, a ruthless leader of the Fire Nation, who demands that everyone live up to his impossible standards, especially his teenage son, Prince Zuko (Dallas Liu). Ozai believes that it is his job to unite the world under the firebender rule, and believes that it’s his destiny to finish a war started by his ancestors.

Kim joins the previously announced cast that includes Liu, Gordon Cormier, Kiawentiio, and Ian Ousley.

The show is written, showrun, and executive produced by Albert Kim. Rideback’s Dan Lin and Lindsey Liberatore are executive producing along with Michael Goi. Roseanne Liang will serve as a co-executive producer, and will also direct alongside Goi, Jabbar Raisani and Jet Wilkinson.

Notably, Kim has previously voiced General Fong in a 2006 episode, and in the 2007 video game. He also voiced Hiroshi Sato on the spinoff series The Legend of Korra.
