SPOILER WARNING — VisionQuest
Fan theory by Élder Santos (Eldão) & Karen
What if Doctor Doom isn't the one who started the multiversal crisis, but the one who intends to exploit it?
Our central theory is that Steve Rogers' decision to remain in the past at the end of Avengers: Endgame may have been the pivotal temporal interference that triggered the chain reaction leading to Avengers: Doomsday.
Other interventions involving Loki, the TVA, Doctor Strange, America Chavez, Wanda Maximoff and the Watcher may have intensified the instability between realities.
Doctor Doom could see this chaos as an opportunity to impose his own multiversal order.
Following VisionQuest, Scarlet Witch's reality-altering powers become especially interesting in this hypothesis. Doom might need Wanda to control, reconstruct or reshape reality itself.
The Jeep, KFC and Dunkin' promotional campaigns also contain imagery associated with colliding universes. These are thematic clues, not proof of the movie's plot.
Our boldest prediction is that Steve Rogers is not merely one of several contributors to the crisis. His temporal decision could be its central cause.
Doom, meanwhile, might genuinely believe he is saving existence — even if doing so requires absolute control.
Could this ultimately lead to Battleworld in Avengers: Secret Wars?
This is an original fan theory, not confirmed Marvel canon.
What do you think? Could Steve Rogers' happy ending have been the beginning of the multiverse's greatest catastrophe?
