Back in April the former head writer of Avatar: The Last Airbender, Aaron Ehasz sent shockwaves through the ATLA fan community. While the original series had ended with three seasons Ehasz revealed on his personal twitter that at one point a fourth season of the series was briefly considered.

The only major plot point he discussed was the character of Azula and that he had always planned for her to have a redemption arc. In her deepest and darkest moment she would have turned to Zuko for help, paralleling his own journey out of darkness. He also said that one of the reasons season 4 didn’t happen was that ATLA co-creators Michael Dante DiMartino and Bryan Konietzko were focusing on The Last Airbender film directed by M. Night Shyamalan.

When we got the chance to speak with Ehasz as he was promoting his new series, The Dragon Prince, at San Diego Comic-Con we had to ask further details about this never seen fourth season. Ehasz was first keen to clarify he didn’t want to sound like he was second-guessing DiMartino and Konietzko. It was simply that, towards the end of season three, he had been asked to think about what a fourth season would have been like.

“In my mind I was always thinking this was going to be a four season arc,” says Ehasz. “Mike and Bryan’s initial plan was three seasons, but there was a period where they were open to the possibility of a fourth season. There was a period where Mike said, “Hey, can you run season four?” Then some of those plans got interrupted.”
