A new rumor is circulating online about Doctor Doom’s first contact with the Multiverse during a failed experiment in Marvel’s Avengers: Doomsday. During filming, a leaked image from the set revealed a mysterious man standing behind a door, and it is reportedly said to be Robert Downey Jr.’s Victor Von Doom.

Note: This report is a rumor shared by user Majestic on X. It is said that the explosion that destroys Doom’s house occurs during a failed experiment to contact his mother’s soul. Doom survives, but his family dies.
According to the rumor, Doom is not completely disfigured, but his pride leads him to cover his face anyway. His mask becomes a symbol of guilt rather than physical wounds.
The rumor also claims that Doom’s mother, Cynthia, made a deal with Mephisto when Victor was born, and she died as a result. That bond would be the true origin of the tragedy.
The laboratory accident not only affects his body, it also connects him with an unknown energy that blends science and magic.
It is rumored that Reed Richards appears indirectly in his story, serving as the one who warns Doom about the mistake he ignores before the disaster.
After the explosion, Doom disappears for years. Some say he is found by monks in the mountains of Tibet, where he forges his first armor.
Doom is said to have placed his mask on his face while it was still red hot, choosing to endure the pain as a reminder of his failure.
His body survives, but his mind is fractured. From that moment on, he begins to hear his mother’s voice, trapped between two worlds.
The experiment is believed to have opened a dimensional rift, a first contact with the Multiverse.
Avengers: Doomsday is directed by the Russo brothers from a screenplay by their longtime collaborator Stephen McFeely and Michael Waldron. The film features cinematography by Newton Thomas Sigel (Bohemian Rhapsody, X-Men: Days of Future Past).
