Avengers: Doomsday Describes the Return of Steve Rogers as a 'Miracle,' but Some Marvel Fans Believe There's More Going on Than Meets the Eye

Avengers: Doomsday might describe the triumphant return of Steve Rogers as a "miracle," but some Marvel fans believe there's more going on than meets the eye.

Yesterday's Avengers: Doomsday trailer was a solemn affair, as it showed the Avengers, New Avengers, and X-Men uniting to take down the seemingly unstoppable threat of Doctor Doom. A fully-powered Thor couldn't make a dent in Robert Downey Jr.'s character, leading him to declare that a miracle was needed... prompting the arrival of former Captain America Steve Rogers.

Of course, audiences have known for months that Chris Evans returns in Doomsday, and in a previous teaser we saw Cap in his house from the finale of Endgame, now holding a baby. But some fans think this new, bearded Steve Rogers in yesterday's trailer is not the same incarnation at all — but a chance for Evans to flex his muscles as an alternate universe Hydra Cap.

There's certainly a marked difference in the look of Evans here to the first Avengers teaser, not that the assembled Avengers would know any different. A shock reveal of Cap being evil would also be a good tactic to stun audiences, who will not share the Avengers' surprise by Evans' return, nor the shock at the reveal of Doom being Downey Jr.

Imagine seeing the scene with Steve Rogers holding his baby at the start of the film, only for his next appearance later on to be a different incarnation working undercover for Doom. It'd be a cool surprise, sold to the audiences (and the Avengers themselves) by the fact that Rogers can still wield Mjolnir.

But he has to be good — he's wielding the hammer! This is a fair reaction, and yet fans are now debating this too. In the comics, Hydra Cap did wield a modified version of Mjolnir, and it's believable that Doom could have manipulated the spell to allow Hydra Cap to fool the others.

Also, that is definitely Hydra Cap.

Whether this really is an evil, Hydra-aligned Steve Rogers remains to be seen, though if it is, it'll be interesting to see where this alternate version has come from. Is he from another corner of the multiverse? Or is he the actual Steve Rogers we know and love, corrupted by Doom's magic? In the Marvel comics, Red Skull rewrote Rogers' history to make him a follower of Hydra's ideology. The storyline led to an epic showdown between good and bad versions of the character, something that would be cool to see on screen before Evans departs the role (again) for good.

Speaking of Doom, we also have a new Avengers: Doomsday poster that teases Doctor Doom's motivation in the story.

Avengers: Doomsday hits theaters December 18, 2026. Here's the official synopsis:
