Marvel fans have plenty of reasons to be excited about Avengers: Doomsday, one of the biggest upcoming films on the 2026 movie calendar. Scheduled to arrive at the end of the year, the film is already shaping up to be a massive event for the Marvel Cinematic Universe.
Not only will it reportedly feature the long-awaited return of Chris Evans as Steve Rogers, but it will also bring the Fantastic Four deeper into the MCU following their big-screen introduction in The Fantastic Four: First Steps.
Now, a new rumor suggests that Steve Rogers and the Fantastic Four may share a major scene in Avengers: Doomsday—and interestingly, it might have originally been planned for an earlier Marvel release.
Steve Rogers and the Fantastic Four: A Scene Fans Were Supposed to See?
According to recent buzz surrounding the upcoming film, Marvel had allegedly planned a significant moment involving Steve Rogers, the Fantastic Four, and Doctor Doom that was supposed to appear much sooner.
The rumor claims that this scene may have originally been intended as an end-credits tag for The Fantastic Four: First Steps, but was removed before the film’s final cut.
Instead of being discarded entirely, it may now be saved for Avengers: Doomsday, where it could play a much bigger role.
If true, this would be a major crossover moment that helps connect Marvel’s newest superhero team with the MCU’s established heroes.
Doctor Doom’s Multiversal Mission
Earlier rumors about Avengers: Doomsday have already suggested that Doctor Doom, played by Robert Downey Jr., will play a central role in the film’s multiverse storyline.
One report claimed that Doom would seek out the Fantastic Four on Earth-828, a universe separate from the main MCU timeline.
It’s still unclear whether Doom originates from that world or if he simply travels there as part of his larger multiversal plans.
The rumor suggests that Doom approaches the Fantastic Four to help stop dangerous incursions—catastrophic multiverse collisions that threaten multiple realities.
From there, the Fantastic Four would travel to the MCU’s primary world, Earth-616, to warn its heroes about the growing crisis.
This idea was reportedly teased in the Thunderbolts end-credits scene, which hinted at major multiversal trouble ahead.
Steve Rogers as the Key to Gaining Trust
The newest rumor adds an intriguing twist: Doctor Doom and the Fantastic Four may recruit Steve Rogers to help them gain the trust of Earth-616’s heroes.
This makes sense, because Steve Rogers remains one of the most respected figures in the MCU.
Even after stepping away from his role as Captain America, Steve’s legacy carries enormous weight among heroes like:
- Sam Wilson
- Bucky Barnes
- Thor
- Bruce Banner
- The remaining Avengers
If Steve Rogers were to vouch for the Fantastic Four, it would immediately make other heroes more willing to listen.
In other words, Steve could serve as the bridge between Marvel’s newest team and the MCU’s established defenders.
Doctor Doom’s Face and the Tony Stark Connection
One of the most fascinating layers of this rumor involves Doctor Doom’s appearance.
Since Robert Downey Jr. is portraying Doom, there’s speculation that Doom may have Tony Stark’s face—either as a disguise, a variant, or something far more complicated.
At the end of The Fantastic Four: First Steps, Doom reportedly shows Franklin Richards his unmasked face, which would presumably resemble Tony Stark.
That alone would be enough to shock Earth-616’s heroes.
Imagine the Avengers seeing the face of their fallen friend Tony Stark… attached to the MCU’s next major villain.
Combined with Steve Rogers’ presence, this could lower the heroes’ guard long enough for Doom to manipulate them.
But of course, Marvel fans know one thing for sure:
Doctor Doom is not to be trusted.
Doom’s Manipulation: The Avengers vs. The X-Men?
Doctor Doom is expected to be the main antagonist not only of Avengers: Doomsday, but also of Avengers: Secret Wars.
So whatever alliance he forms with the Fantastic Four and the Avengers is almost certainly part of a larger scheme.
Another rumor claims that Doom may lead both teams into the X-Men universe, which could be the source of the next major multiversal incursion.
The wording of the report suggests Doom might manipulate events so that the Avengers and Fantastic Four end up battling the X-Men.
If true, this would set up an explosive crossover:
- Avengers vs. X-Men
- Fantastic Four caught in the middle
- Doom pulling the strings behind the scenes
This kind of conflict would fit Doom’s character perfectly—using heroes as pawns in his quest for power.
Steve Rogers’ Reaction When the Truth Comes Out
If Steve Rogers truly becomes involved in Doom’s plan, one major question arises:
How will Steve react when he learns he was being used?
Steve Rogers is known for his strong moral compass and deep sense of responsibility.
If Doom tricks him into helping gain the Avengers’ trust, Steve would likely feel betrayed—and possibly guilty for allowing the villain access.
This could lead to an emotional arc where Steve must confront his return to a world that has changed, while also dealing with the consequences of Doom’s deception.
Captain HYDRA Rumors Seem Unlikely
Some fans had previously theorized that Avengers: Doomsday might introduce an evil version of Steve Rogers, similar to the controversial “Captain HYDRA” storyline from the comics.
However, based on the Steve-focused teaser released recently, that doesn’t appear to be the direction Marvel is taking.
Instead, it looks like audiences will reunite with the Steve Rogers last seen after Endgame, when he traveled through time to return the Infinity Stones.
This would be long before he reappeared as an elderly man and passed the shield to Sam Wilson.
So rather than an evil Steve, the film may focus on the heroic Captain America fans remember.
Take the Rumor With Caution
As exciting as this rumor sounds, it’s important to remember that Marvel has not confirmed any of these details.
Scenes change, end-credit tags are often reworked, and storylines evolve during production.
For now, fans should treat this as speculation until official trailers or announcements provide more clarity.
Still, the idea of Steve Rogers teaming up with the Fantastic Four—while Doctor Doom lurks in the background—would be one of the most intriguing MCU moments in years.
With Avengers: Doomsday set for release on December 18, 2026, more concrete details are likely to emerge as the premiere draws closer.
