The Real Ages of Netflix’s ‘Avatar: The Last Airbender’ Cast Will Make Your Head Spin

With Season 2 of ‘Avatar: The Last Airbender‘ now streaming on Netflix, the conversation around the live-action Gaang has reignited in a very specific way. Fans are not just talking about earthbending and Ba Sing Se conspiracies. They are talking about just how much the cast has aged up since those first audition tapes.

The series’ first season premiered on Netflix on February 22, 2024, and the second season followed on June 25, 2026. That is over two years between drops, and for a cast playing cartoon teenagers, time has been both kind and mildly chaotic. Here is a full breakdown of where the main ‘Avatar: The Last Airbender’ actors stand age-wise heading into Season 2, along with their characters’ ages for comparison.

Quick Reference List: ‘Avatar: The Last Airbender’ Cast Ages (Season 2, 2026) Gordon Cormier (Aang) — 16, Kiawentiio (Katara) — 20, Ian Ousley (Sokka) — 24, Dallas Liu (Zuko) — 24, Elizabeth Yu (Azula) — 23, Miyako Cech (Toph) — 19, Paul Sun-Hyung Lee (Iroh) — ~53.

Gordon Cormier as Avatar Aang — 16 Years Old

Gordon Cormier’s career was fairly new when he was cast in ‘Avatar: The Last Airbender’, with earlier roles coming in TV shows such as ‘Get Shorty’, ‘Lost in Space’, and ‘The Stand’. His casting as the 12-year-old Avatar was therefore a significant leap, and one that paid off with a massive global following almost overnight.

For the second season of Netflix’s adaptation, Gordon Cormier is 16. That four-year gap from the character’s canonical age is already attracting attention, but even the show’s creative team has leaned into it. Executive producer Christine Boylan noted that “Gordon is the Aang you want, but he’s also flesh and blood, a person growing up before your eyes, exactly like Aang would have if he were not animated.”

Kiawentiio as Katara — 20 Years Old

Kiawentiio is a First Nations actress who has starred in films and TV series including ‘Beans’, ‘What If…?’, and ‘Anne with an E’. For her, landing the role of Katara was not just a career milestone. She described herself as a “super huge mega fan” of the original animated series, telling Netflix that she never thought playing Katara could become her reality.

Katara is 14 years old in the original source material, but her actress Kiawentiio is 20 in Season 2. A six-year gap between actor and character is not unusual in Hollywood by any stretch, but when the character is drawn as a young teenager, it does put a fresh spotlight on the casting math as the show progresses.

Ian Ousley as Sokka — 24 Years Old

Ian Ousley is an American actor whose previous credits include recurring arcs on ’13 Reasons Why’ and ‘Big Shots’, along with guest appearances on ‘Young Sheldon’ and ‘Sorry for Your Loss’. He is also a black-belt and former champion martial artist. That background in combat sports made him a natural fit for a character who relies on strategy and physical combat rather than bending.

Sokka is slightly older than the rest of the core trio in the original show, but only marginally at 15. In the Netflix show, he is played by Ian Ousley, who is 24. The showrunners seem unbothered by the disparity, and Season 2 executive producer Christine Boylan praised Ousley’s dramatic depth, saying “Sokka is a genius, Sokka is an engineer, and Ian was able to embody that kind of person who thinks 20 steps ahead.”

Dallas Liu as Prince Zuko — 24 Years Old

Dallas Liu is an American actor born in Los Angeles, California. His earliest appearances came in martial arts-centric movies and shows, including ‘Tekken’ and ‘Mortal Kombat: Legacy’, along with a brief role in ‘Shang-Chi and the Legend of the Ten Rings’. His background in martial arts proved invaluable when bending bootcamp came calling.

Dallas Liu plays Zuko, who is 16 years old in the original show. In real life, he is actually 24. Despite that eight-year difference, Liu remains one of the most praised castings in the entire series, and his enthusiasm for the story has not dimmed. In a behind-the-scenes video ahead of Season 2, Liu could be heard saying “Now that we’re past Season 1, we’re into the real meat of the story.”

Elizabeth Yu as Princess Azula — 23 Years Old

Elizabeth Yu was born on October 6, 2002, in New Jersey. Before ‘Avatar: The Last Airbender’, she appeared in the comedy film ‘Somewhere in Queens’ and the drama film ‘May December’. Her casting as Azula was one of the most anticipated reveals for fans of the animated original, and she did not disappoint.

Upgraded to a main character for Season 2, 23-year-old Elizabeth Yu plays 16-year-old crown princess of the Fire Nation, Azula. To prepare, Yu trained five days a week to build up strength before even arriving on set to prepare for the physicality of the role. That dedication has translated into one of the most compelling performances in the new season.

Miyako Cech as Toph Beifong — 19 Years Old

Miyako was announced as having joined the main cast as Toph Beifong for the second season in September 2024. Toph is one of the most beloved characters in the entire ‘Avatar’ universe, a blind earthbending prodigy whose arrival was already the most talked-about addition heading into Season 2.

Miyako Cech is fully 19 playing a 12-year-old Toph. The production even made 20 pairs of fake feet for the character, and the team worked with blindness experts to help Miyako step authentically into the role. That level of care signals just how seriously the production is taking its most fan-celebrated new addition.

Paul Sun-Hyung Lee as Uncle Iroh — ~53 Years Old

Paul Sun-Hyung Lee was 51 at the time of the Netflix series premiere in 2024. His character Iroh is Zuko’s uncle and the older brother of Fire Lord Ozai, who accompanies Zuko on his journey to capture the Avatar. Lee is arguably the most naturally age-matched cast member in the entire series, stepping into a role that feels written for exactly his stage of life.

Lee put in substantial work to embody Iroh, including physical training he credits to co-star Dallas Liu. He recalled telling Netflix that learning to breathe and stand correctly for his one action sequence took five full days of preparation, adding that there were “a lot of Epsom salt baths” involved. That honest, self-aware commitment to the craft is exactly the kind of energy that has made Lee’s Iroh a fan favourite across both seasons.

Does the growing age gap between this cast and their beloved animated counterparts change anything about how you see the show, or does the quality of the performances make it irrelevant?
