Ackles and Aya Cash will play Soldier Boy and Stormfront, respectively, in the upcoming series.

The majority of The Boys’ Hall H panel at San Diego Comic-Con on Friday morning was a victory lap commemorating the most memorable moments from the just released season 4. Showrunner Eric Kripke couldn’t say anything about the upcoming season because he and the writers had just been working on it for two months. However, the panel concluded with a surprise appearance from a guest who revealed exciting news about another spinoff to further extend the universe of The Boys.

Moderator Jeffrey Dean Morgan couldn’t wait to introduce his Supernatural son Jensen Ackles in the last seconds of the panel. Ackles’ return as Soldier Boy was hinted at the end of Season 4, and Kripke stated that he will be a series regular in Season 5. But that is not all! Ackles will also play the role in Vought Rising, a new prequel series set in the 1950s at the start of the superhero era.

Ackles said that the new show “will be a lurid pulp prequel set in New York City at the dawn of the ’50s about the humble beginnings of the Vought Corporation.”

Ackles will be joined by another former star of The Boys: Aya Cash, who will be reprising her role as Stormfront in the series. Although Stormfront was initially presented as a new member of the Seven, she was actually a long-lived Nazi and the very first subject of Frederick Vought’s superpower serum Compound V. So it makes sense that she would be a factor in this new ‘50s-set series.

Cash couldn’t be at the panel in person, but she did appear via video clip to further tease Vought Rising. “I am so excited about working with Jensen,” Cash said in the video. “I think this thing is gonna be incredible. We’ve got everything from Judy Garland to Joe McCarthy. How? I don’t know, I didn’t write it. But I have read it, and it’s really really good.”

In a press release, Kripke and series showrunner and executive producer Paul Grellong described the upcoming series as “a twisted murder mystery about the origins of Vought in the 1950s, the early exploits of Soldier Boy, and the diabolical maneuvers of a Supe known to fans as Stormfront, who was then going by the name Clara Vought.”

“We cannot wait to blow your minds and trouble your souls with this salacious, grisly saga drenched in blood and Compound V,” they added.
