First came Avatar: The Last Airbender, an animated series that ran for three seasons from 2005-2008, about a young boy named Aang with spectacular powers destined to unite a fantasy world at war. Then there was The Legend of Korra, which ran for four seasons from 2012 to 2014; this one followed Aang's successor, who got his powers when he died.
Then the series lay quiet until last year, when Netflix debuted a new live-action remake of the original show. Also, the guys behind the original series — Bryan Konietzko and Mike DiMartin — formed Avatar Studios, which will work on new animated projects; they're already working on a movie about a grown-up Aang due out in January of 2026. Suddenly, The Last Airbender universe is busier than it's ever been.
Avatar Studios has several projects in development beyond the Aang movie. According to Knight Edge Media, one of them is a whole new Avatar TV series set after The Legend of Korra, focusing on the person who inherits her powers. Although we haven't confirmed this, Knight Edge Media reports that the first two episodes of this series are already in pretty good shape, and has some plot details to share with the world. Beware potential SPOILERS beyond this point.
Per Knight Edge Media, the next Avatar will be an Earthbender, which lines up with the cycle established by the previous shows. She will one of two amputee twins. For whatever reason, her sister was raised by the Order of the White Lotus — a powerful society we first met in the original show — while she was cast aside and lost. When we meet her, she is homeless. She's also missing her left leg and has some kind of large feline-type creature as a familiar.
Eventually, the new Avatar will reunite with her sister and the two will train together. Also of note is that, in that new show, the four nations fans have become familiar with — the Water, Air, Fire and Earth nations — are no more. Apparently, some cataclysmic event during Korra's time will lead to the world being reshaped into seven "havens."
In 2024, a novel called Avatar, the Last Airbender: The Reckoning of Roku revealed that Avatar Roku — the Avatar before Aang — had a twin brother, so the idea of the Avatar being a twin has been explored, if not onscreen. I also can't help but look at this idea and think of several other recent genre TV shows that have focused on pairs of sisters, including Arcane, Dune: Prophecy and Star Wars: The Acolyte, which also featured long-sundered twins. Sometimes, when one idea catches on in Hollywood, it spreads. This might be one of those times.
Of course, right now, this is all rumor, but expect to see a lot more of The Last Airbender universe in the coming years. Right now, the race to see what will come out first: the animated movie about adult Aang or the second season of Netflix's Last Airbender live-action remake.
