A brand new "secret" Avatar: The Last Airbender TV series is currently in the works, it has been revealed!
Update (8/14) - Paramount has filed to trademark Avatar Kuruk: Wave of Chaos for a potential new Avatar series along with toys and merchandising. It's currently unknown whether this project is related to Avatar: Red Thunder, although both are set to feature waterbenders.
Speaking to GamesRadar+ at Comic-Con International: San Diego 2026 about what's coming up next for Avatar: The Last Airbender, Michael Dante DiMartino, the co-creator of Nickelodeon's iconic Avatar franchise, teased "There's stuff in development, just TV shows in production, but not features at the moment."
"We have another secret thing in production, but yeah, it's on the series side," added co-creator Bryan Konietzko. "To be clear, we're series people, so that's okay to us. Features is a new thing to us."
We already knew something was in the works thanks to previous comments from Konietzko. "The [Avatar] Aang movie was just one of a whole slate," he shared. "I'm working on another thing, which we'll announce when the time's right."
The news comes at the first project announced under Nickelodeon's Avatar Studios label, the movie Avatar Aang: The Last Airbender, is released on Paramount+ on Saturday, July 25. This will be followed by the brand new series, Avatar: Seven Havens, set to premiere on Paramount+ on Friday, October 9.
The original plan was for three feature-length films, however, things have changed slightly since Paramount merged with Skydance. The first of these changes were announced in December, with Paramount+ becoming the home of all new Avatar content produced under the Avatar Studios label. Beforehand, Avatar Aang was originally slated for theaters, and Avatar: Seven Havens for Nickelodeon.

New Villain Details For Avatar Studios ‘Avatar: Red Thunder’ Animated Series (EXCLUSIVE)
The very first antagonist details have been revealed for the secret Avatar: Last Airbender animated series titled Red Thunder.
Last summer, we at Knight Edge Media brought you the first character details of a secret animated series in development at Avatar Studios under the working title Red Thunder. This new series will take place in a different era from their previously announced Avatar: Seven Havens series, most likely in the distant past. While the project was not officially announced or titled, Avatar: The Last Airbender co-creator Bryan Konietzko confirmed at SDCC 2026 that a show exists but will be fully revealed at a later date. The character descriptions from a casting call last summer were for a new teenage Water Tribe Avatar codename “Baroo” and his future chief of the Water Tribe friend “Meebs”. (These codenames are only for the casting call process and won’t be used in the final cut of the series.) The studio was looking for teenage Indigenous/First Nations actors for the role. It will most likely be complete unknowns, just like Avatar Pavi (played by Shaeli Khan) and Nisha (played by Aishu Devan) were in Seven Havens. Apparently, there were multiple rounds of casting for the roles of Meebs and Baroo in both 2024 and summer 2025 (see below).
We also learned that the antagonist of the series will be a female Water Tribe leader codename “Deela”. She will also be Meebs’ mother in this story. We have also exclusively learned that a high-profile Indigenous actress was in talks for the role. Interestingly, the role of Deela appeared only in the 2024 casting call, not in the 2025 one, which means the actress could have remained signed on throughout both casting processes. Paramount is high on this series, as they see the Avatar: The Last Airbender franchise as more geared towards boys than girls, even though Seven Havens will feature twin female heroines. The loglines from both casting calls are only slightly different but tell the same premise:
2024 -“A teenager ventures into mysterious lands cursed by ice, only to discover his former teacher–and now hunter–is behind it all. Now he must break the curse and free the world, all while having a little chaotic fun along the way.”
2025 – “A rebellious teenager bucks thousands of years of tradition to go on globetrotting adventures, staying one step ahead of his angry teacher, rowdy pirates, and chaotic gremlins–all while helping the world in his own unique ways.”
From what we have learned, the main premise of the story is that it takes place during an Ice Age (possibly inspired by the on-hold AAA video game), with the Water Tribe as the villain nation. So what happens when an Avatar is born into an aggressive nation? While Avatar Roku comes to mind, he had to die for Firelord Sozin to wage war on the Air Nomads. Avatar Kyoshi also had to deal with Emperor Chin and the conquest of the Earth Kingdom. However, both Roku and Kyoshi were already adults by that time, not teenagers. The pilot has been done for a while, but the show hasn’t been fully picked up just yet.

Viacom Registers ‘Avatar Kuruk: Wave of Chaos’ Trademark For Avatar Studios
A new trademark was registered by Viacom International for a new Avatar Studios property titled Avatar Kuruk: Wave of Chaos.
Today, a new trademark was registered by Viacom International for a new Avatar Studios property titled Avatar Kuruk: Wave of Chaos. While trademark registrations could mean almost anything from video games to novels to clothing, it was registered under Class 41. Classification 41 specifies “Entertainment Services, namely, the provision of continuing in multimedia programs featuring animation delivered by television, satellite, the internet and computer networks.” So it’s very possible this is something animated-related.
We at Knight Edge Media have already revealed in 2025 that a secret Water Tribe animated series was in development under the working title Red Thunder. However, the casting calls used codenames for all the characters (i.e “Baroo”). So it was hard to determine if it was a new Avatar series or based on a previously established Avatar like Kuruk. We were told the series takes place during an Ice Age; however, we don’t know if it’s the same Ice Age from the on-hold AAA video game, which is 7,000 years before Aang’s time. While Avatar Kuruk lived only a few hundred years before Aang. It should be noted that the logline for Red Thunder did read,
“A rebellious teenager bucks thousands of years of tradition to go on globetrotting adventures, staying one step ahead of his angry teacher, rowdy pirates, and chaotic gremlins–all while helping the world in his own unique ways.”
It’s possible they took the AAA game premise since it’s no longer technically canon and simply gave it to Kuruk, but we really don’t know. We’ll have to wait and see whether this trademark is the same as the secret Red Thunder series. This is mostly speculation, trying to connect the two until it is officially announced.
Avatar: Red Thunder and Avatar Kuruk: Wave of Chaos have no set release date
