A fourth season for Batman Beyond is a possibility if the recently announced Blu-ray set sells well. Batman Beyond originally premiered in 1999 and followed Terry McGinnis as the new Batman under the guidance of an elderly Bruce Wayne.
Although many fans were skeptical before it premiered, Batman Beyond would go on to be one of the most acclaimed DC animated shows of all time. It expanded on the mythos of Batman's universe, bringing the continuity of Batman: The Animated Series many years into the future. Fans praised the serious storytelling, the characterizations of Terry, Bruce, many of the villains, and the overall unique atmosphere of Neo-Gotham. The show ran for three seasons and was followed by the film, Batman Beyond: Return of the Joker. That seemed to be the end of Terry McGinnis in animation, but the character was brought back twice in Justice League Unlimited. Batman Beyond was also adapted for the comics, which is currently running. Fans have been hoping for years that the show would see a revival; and now a fourth season isn't out of the question.
During the Batman Beyond panel at San Diego Comic-Con (via CBR), a young fan dressed as Terry McGinnis asked series co-creator Bruce Timm when the next season would be released. Timm responded that it could happen, but only if the new Blu-ray sells well and gets people talking. He said:
"I'll tell ya - if this thing sells like crazy on Blu-ray and creates a giant buzz, that will make it more possible that it would happen. We would totally do it."
Timm's response is to the point - if fans want a fourth season, it's important for Warner Bros. to see there is a large demand for more Batman Beyond in animation. This is the first time Batman Beyond has been released on Blu-ray, and it even contains Return of the Joker. So, it should sell well, but it remains to be seen if it sells well enough to justify a new season.
An interesting thing to ponder is if Batman Beyond season 4 was to be made, when would it take place? It could either take place after the events of Return of the Joker, or possibly after the Justice League Unlimited episode, "Epilogue," which took place many years after the film. Perhaps it could go even further, taking place after Bruce has passed away, and now Terry has to work alone as Batman. It's fun to think about, but fans will have to wait and see how the Blu-ray set sells when it releases in October. And the future could be bright. If Young Justice was able to make a comeback after being canceled, anything is possible.
