Not that fans are happy with the development. It was one thing to turn Captain America into a Hydra agent. It was another to reveal that the entirety of Marvel Comics history was a lie and that Steve Rogers — along with Hydra — were the true winners of World War II.
Secret Empire #1 takes place about a year after the Captain set off a chain of events that would put Hydra back in control. History books have been fixed, Big Brother is even bigger, and anyone exhibiting any forms of superpowers must register with the government.
Many of Earth’s mightiest heroes are still in space, locked out by a global shield. Those on Earth unwilling to accept the new way of things have either been imprisoned or have been forced into hiding, hoping to maintain some safety from the Dreadnoughts, Hydra’s Sentinel-like robots.
