Secret Empire is a 2017 Marvel Comics limited series and crossover storyline. This limited series event addresses the aftermath of the crossover event Avengers: Standoff! and the ongoing series Captain America: Steve Rogers, in which Captain America has been replaced by a version of himself loyal to Hydra, who has been acting as a sleeper agent and covertly setting the stage to establish Hydra as the main world power.

The initial groundwork for Secret Empire was laid in the 2016 limited crossover series Avengers: Standoff! by Nick Spencer, Mark Bagley, and Jesus Saiz. In Standoff there was a moment that Captain America was transformed into his "former" self by Kobik, reverting him from a 90-year-old man to a young fit adult. This transformation was explored further in the ensuing ongoing series Captain America: Steve Rogers in which the transformation is revealed to have been masterminded by the Red Skull altering Captain America's memories making him a HYDRA agent and setting forth a plan to bring the American government to its knees and enable HYDRA to become the world-power that it was always meant to be. Throughout the rest of 2016 and the first half of 2017, subsequent issues of Captain America: Sam Wilson, Thunderbolts and Captain America: Steve Rogers along with certain issues of Uncanny Avengers and U.S.Avengers and the limited series event Civil War II unveiled how Captain America planned to alter the playing field covertly without the rest of the heroes becoming aware of his plan.

In early 2017 Marvel began to release teaser posters in anticipation for the Secret Empire event. One month after the posters were released it was announced that the limited series would be sold twice monthly and would be a total of nine issues including a prelude issue serving as #0, with issue #1 set to be released in May 2017 and issue #8 would end the limited series in August that same year. Editor-in-chief Axel Alonso went on to mention that one of the main purposes for this event was to bring the heroes within Marvel back together ever since the divisive events of the Civil War II and the Inhumans vs X-Men storyline as a unified group against a common foe as the Avengers, Defenders, Guardians of the Galaxy, Inhumans, X-Men, Ultimates, and Champions would all have a stake in this event. In March it was revealed that some of the members of the creative team included Steve McNiven (Monsters Unleashed), Nick Spencer (Captain America: Steve Rogers), Andrea Sorrentino (Old Man Logan), and Leinil Yu (Star Wars). In April it was announced that following the close of Secret Empire would be an 18-month hiatus for Marvel from big crossover events, the company's longest consecutive gap without any major crossovers in twelve years. Issue #0 was released on April 19, 2017 and the first issue was released on May 3.

The storyline deals with HYDRA's takeover of the Marvel Universe after Captain America is revealed to be one of their agents ever since the sentient Cosmic Cube Kobik affected his memories upon Red Skull's clone using her powers on him. This causes the rest of the superheroes to join forces and rebel against their former leader and friend to prevent the United States from falling under Hydra's control.

Steve Rogers (Hydra Supreme) has not been a contender in any CBUB matches.
