New Marvel Report Reveals Steve Rogers’ Biggest Mistake, And Its Avengers Doomsday Consequences

According to a new report, a significant error Steve Rogers (Captain America) made in Avengers: Endgame will have lasting consequences and play a role in the storyline and motivations of Doctor Doom in the upcoming Avengers: Doomsday. Rogers’ time in the Marvel Cinematic Universe concluded with a memorable finale in Endgame, including moments like proving himself worthy of Thor’s hammer, leading the fight against Thanos, restoring the Infinity Stones, and traveling back in time for a life with Peggy Carter. Despite a seemingly complete ending, some aspects of his story remain open for further exploration.

According to entertainment news source My Time to Shine, Steve Rogers’ decision to go back in time and build a life with Peggy Carter has huge consequences for the Multiverse and the upcoming Avengers: Doomsday film. They suggest he effectively “sacrificed” the stability of reality to be with the woman he loved.

“He really sacrificed the multiverse just so he could be with his girl again.”

Sources say Chris Evans is coming back to play his Marvel character in Avengers: Doomsday, and he’ll be acting alongside Robert Downey Jr. – though this time, Downey Jr. will be playing a villain seeking revenge. Details about how Captain America fits into the larger multiverse story are still a secret.

In September 2025, sources reported that a scene featuring Peggy Carter, Steve Rogers, and Doctor Doom (played by Robert Downey Jr.) was being filmed. This suggests the scene happens sometime after the end of Avengers: Endgame, where Steve and Peggy are shown dancing together in the 1970s.

Doctor Doom is relentlessly hunting Steve Rogers, but it’s unclear why. While the breakdown of the Multiverse likely plays a role, Doom’s personal involvement suggests there’s a deeper, more personal reason behind his pursuit.

The upcoming Marvel movie, Avengers: Doomsday, directed by the Russo Brothers, will feature a huge team of heroes battling Doctor Doom to save the Multiverse. Chris Evans is returning, and the film also stars Chris Hemsworth, Pedro Pascal, Vanessa Kirby, Florence Pugh, Patrick Stewart, James Marsden, Kelsey Grammer, Ian McKellen, and a large ensemble cast. It’s scheduled to hit theaters on December 18, 2026.

How Steve Rogers’ Mistake in Avengers: Endgame Could Lead to His Downfall

Although Avengers: Endgame gave Steve Rogers a satisfying conclusion, some believe his choice was selfish. He left the timeline he promised to defend and intentionally created a new one, which could have serious consequences, potentially even causing dangerous disruptions to reality.

The disruptions might have damaged Doctor Doom’s home world, forcing him to move to the Fantastic Four’s Earth. There, he could be trying to figure out what caused the destruction and why it happened, ultimately leading him to Steve Rogers. This could be the reason Doctor Doom holds such a strong personal grudge against Rogers, and what sparked his dangerous plan for the Multiverse.

It’s unclear if Steve’s time travel started the problems with different universes colliding, but it seems his actions are definitely contributing to them. Because of this, the Avengers leader might choose to sacrifice himself to stop Doctor Doom from taking over.

Steve’s choice actually positions Avengers: Doomsday as a direct follow-up to Avengers: Endgame, solidifying how all the stories in the Marvel Cinematic Universe are connected and bringing the Multiverse Saga to a close.
