The Legend of Aang: The Last Airbender, the upcoming feature-length addition to the Avatar universe, has finally confirmed the actor behind one of its most iconic characters.
Steven Yeun, widely recognised for his roles in The Walking Dead and Invincible, will voice the adult version of Zuko, Aang’s one-time enemy, later friend and mentor, in the 2026 animated film.
Yeun’s casting had sparked speculation earlier this year when he was announced as part of the film's ensemble in an unspecified role. Many fans assumed he might reprise his part as Avatar Wan from The Legend of Korra, but creators Michael Dante DiMartino and Bryan Konietzko confirmed during San Diego Comic-Con that Yeun is now stepping into the role of Fire Lord Zuko.
Konietzko stated, “Steven Yeun was Avatar Wan. He played the first Avatar in The Legend of Korra. We loved working with him, and we're excited to have him back in the universe.” Although it's still unclear whether Yeun will also return as Wan, the creators emphasised their excitement about his expanded role in the Avatar world.
Joining Yeun are Eric Nam, Jessica Matten, Román Zaragoza, and Dionne Quan as Aang, Katara, Sokka, and Toph, respectively. The film explores Team Avatar's adult lives and bridges the narrative gap between The Last Airbender and The Legend of Korra.
The film is directed by Lauren Montgomery and co-directed by William Mata, with DiMartino and Konietzko producing. It’s slated for release on October 9, 2026.
