Captain America has been a secret Hydra agent from the start. Marvel revealed this in “Captain America: Steve Rogers #1.” What would this comic book twist mean for future movies? Will Steve Rogers now be the villain in “Avengers: Infinity War?”

This reveal shocked a lot of die-hard fans. But Marvel executive editor Tom Brevoort said this twist has been thought of for a long time. “It’s been in the works for more than a year,” Brevoort told Time. “Nick Spencer, who is the writer of the series, pitched us the story as part and parcel of restoring Steve to his youth and vigor.”

Spencer, for his part, explained that a previous writer, Rick Remender, has been working towards a similar reveal before he came in. “[Remender] had been building towards this story of Hydra having infiltrated various institutions of government and various super teams. I thought that sounded like too big of a story,” he told Entertainment Weekly. “I drilled it down and thought, what if there’s just one very valuable Hydra plant?”

The Marvel writer said he soon realised there was no character who can be a “more valuable” secret Hydra agent than Steve Rogers. “It was really obvious straight away that there’s nobody who could do more damage … That was really the genesis. It sprang pretty organically from story ideas that were already on the table,” Spencer explained.

Does this mean Steve Rogers will be out to destroy the Avengers in the upcoming “Infinity War” movie? No word as of yet can confirm this. However, Brevoort said this twist could change the Marvel universe for good. “It means … that the most trusted hero in the Marvel universe is now secretly a deep-cover Hydra operative,” he said. “That makes every interaction he has with anyone take on a second layer, a second meaning.”
