A new report about the upcoming Avengers: Doomsday has potentially revealed more of what we can expect from the backstory of Robert Downey Jr.’s Doctor Doom.

What do we know about Doctor Doom’s past ahead of Avengers: Doomsday?

Insider MyTimeToShine recently took to social media to reveal what a cryptic post from 2025 meant. Back in September, the insider shared a photo that the Russo Brothers had shared, showing off a piece of Doomsday’s set, with the cryptic message of “look hard” attached.

The insider noted that he can now reveal that image comes from a set where they filmed a scene feature Doom and his family in the movie. The post mentions that the scene will show Doom and his family in a lab, where an experiment goes awry and kills his family, while also damaging his own body.

While it’s unconfirmed that the scene is that, it would go a long way in corroborating the reports that Downey Jr. is playing the actual Victor Von Doom. MyTimeToShine goes on to note that Chris Evans’ Steve Rogers indirectly causes this to happen via movement from other universes, which ends up leaving Doom blaming Rogers for it.

He doesn’t, not directly. But by moving to a universe where he doesn’t belong, he triggered the Incursion. Doom then spent years trying to fix it in secret, and one of his experiments literally blew up in his face. So he blames Steve.— MyTimeToShineHello (@MyTimeToShineH) February 27, 2026
