Albert Kim, who replaced creators Michael Dante DiMartino and Bryan Konietzko, is handing over the series to colleagues Christine Boylan and Jabbar Raisani.

Sources say Kim’s intention was to lay the foundation for season one of Avatar: The Last Airbender after stepping in for the beloved franchise’s creators. Given the long turnaround time in crafting the series — Netflix ordered it in 2018, the creators left in late 2020 and the show didn’t debut until February 2024 — sources say Kim was ready to move on to new opportunities.

Co-executive producer Christine Boylan and exec producer/director Jabbar Raisani — both of whom were hired by Kim — will take over as the drama’s third showrunners for the previously announced second and third seasons.
