Summary
A newThe Fantastic Four: First Stepsset video could have revealed a major plot point, and aMarvel Cinematic Universetheory explains how that could tie the team and Robert Downey Jr.’s Doctor Doom. At the moment, RDJ’s Victor von Doom has yet to be officially confirmed as a member of theFantastic Four reboot’s cast. However,Doctor Doom will reportedly make his first MCU appearance inThe Fantastic Four: First Steps' mid/post-credits scenebefore starring in 2026’sAvengers: Doomsday.
RDJ’s Doctor Doom is now the new main villain of the Multiverse Saga, replacing Kang the Conqueror. Setting up the character before his major role in theupcoming MCU movieswould not be the most shocking idea, especially with a debut alongside the Fantastic Four. Not only is Doom the team’s biggest villain in the comics, but the Fantastic Four have been confirmed to appear in the next two Avengers movies, just like RDJ’s Doctor Doom. As such, the heroes and the villains will be linked in the MCU, and aFantastic Four reboottheory deepens that bond.
Galactus and the Silver Surfer are confirmed to appear in The Fantastic Four: First Steps.
I’m Convinced The MCU Is Hiding A Key Fantastic Four Suit Change In Plain Sight

Sue Storm Is Holding A Baby In The Fantastic Four: First Steps Set Video
The Marvel Team Could Be Larger In The Movie
AnewThe Fantastic Four: First Stepsset videoof Vanessa Kirby’s Sue Storm might have confirmed a key plot point for the new MCU movie. In the set video, Sue is seen holding a baby. In the comics,Sue Storm and Reed Richards have two kids, Franklin and Valeria. For some time now, even before Pedro Pascal and Vanessa Kirby had been cast as the MCU’s Reed and Sue, the characters had been rumored to be parents in the Fantastic Four reboot.
The movie’s title could be a reference to a child’s first steps at the same time as a nod to the Fantastic Four arriving in the MCU.
Franklin and Valeria appearing inThe Fantastic Four: First Stepswould make sense for a few reasons. First is the fact thatthe kids were members of the Future Foundation in the comics, an organization that has been teased for the movie. Franklin’s reality-altering powers also played a role in the aftermath of the comics' Secret Wars, which the MCU could use. Finally, the movie’s title could be a reference to a child’s first steps at the same time as a nod to the Fantastic Four arriving in the MCU.

RDJ’s Doctor Doom Could Be The Godfather Of Valeria Richards
The Villain And The Team Could Be Established In Their World
In Marvel Comics, Doctor Doom is Valeria Richards' godfather. The MCU could go in that direction with RDJ’s Doom, cementing his intimate bond to this version of the Fantastic Four from the get-go. AsThe Fantastic Four: First Stepsis all but confirmed to take place in a different universe, the movie could reveal that the team and Doom have already been active for several years, with Reed and Sue parents to a young Franklin and Valeria. This way, the reboot can show flashes of the Fantastic Four and Doctor Doom’s backstories before they fight in the next Avengers movies.
