Avengers: Doomsday may be bringing Earth’s Mightiest Heroes together for the first time since 2019, but they’re not the only superhero team appearing in the upcoming Marvel movie. The MCU’s Fantastic Four will be back in action on the 2026 movies schedule following their introduction last summer, and we’ll also reunite with many characters from the old X-Men franchise. These heroes and many more will band together against the multiversal threat that is Doctor Doom, but now there’s a wild Doomsday rumor claiming that Robert Downey Jr.’s new MCU character has something strange planned for the Fantastic Four and X-Men.
We briefly met Downey’s Doom in The Fantastic Four: First Steps’ mid-credits scene when he was shown kneeling in front of Franklin Richards, with his mask in hand, four years after the main events of the movie. Victor von Doom is best known as the Fantastic Four’s arch-nemesis, but if scooper @MyTimeToShineHello is to be believed, he’ll actually seek out the team in Doomsday to help stop the incursions affecting the multiverse. From there, they head over to the main MCU reality to warn its heroes, which lines up with the Thunderbolts* post-credits scene.
