The Boys’ fourth season ended on a nightmarish note that made the show’s upcoming final chapter seem like it’s going to its most deranged. But during this year’s San Diego Comic-Con, Amazon revealed that while The Boys may be coming to an end, the larger franchise is about to get even bigger with a prequel series set in the distant past.

Though The Boys showrunner Eric Kripke was tightlipped about the show’s series finale, he was all too excited to bring actor Jensen Ackles on stage during a panel to announce the forthcoming arrival of Vought Rising, a new prequel series. Set in the ‘50s, Vought Rising will chronicle the lives of Soldier Boy (Ackles) and Stormfront (Aya Cash) — two of Vought’s earliest and most powerful superhumans.

In a press release about the new show, Kripke described Vought Rising as a “twisted murder mystery” that, in addition to being “soaked in blood and Compound V,” will delve into how Vought became a nefarious megacorporation. Paul Grellong is attached to showrun and executive produce the series, which does not yet have a projected premiere date.
