AVENGERS: DOOMSDAY Theory Explains Why Doctor Doom Is Targeting the MCU’s Children
When it comes to Marvel, right now, all eyes are on Avengers: Doomsday, easily one of the most anticipated Marvel movies on the release calendar. With very little officially revealed, theories are filling the gaps, and one of the latest ideas floating around is especially dark.
It suggests that Robert Downey Jr.’s Doctor Doom’s plan may involve stealing children across the multiverse. Even more interesting, it sounds a lot like something we just saw play out in Stranger Things.
Directed by Anthony Russo and Joe Russo, Avengers: Doomsday is being kept tightly under wraps. That mystery has pushed fans to read deeply into early footage, teaser moments, and recent MCU breadcrumbs.
Anyone who’s watched Stranger Things knows the final season recently wrapped up on Netflix, showing Vecna kidnapping children as part of a larger plan to reshape reality itself. A new rumor tied to Doomsday, shared by ScreenRant, has fans wondering if Doctor Doom might be pulling from a similar playbook.
This theory points to several curious details. Early Doomsday footage includes Captain America shown with his infant child. Thor, meanwhile, appears alongside his adopted daughter Love.
Then there’s the credits scene from Fantastic Four: First Steps, which only adds fuel to the fire. Taken together, fans believe these moments aren’t random. The idea is that Doctor Doom may be targeting the children of this shared universe.
According to the theory, Doom isn’t just kidnapping kids for leverage. He’s allegedly collecting superpowered children to replace existing Anchor Beings throughout the multiverse. Because they’re young, the theory claims he could manipulate them, mold their beliefs, and shape entire universes to his liking. That’s pretty close to Vecna’s plan in Stranger Things Season 5.
At this stage, it’s important to keep expectations in check. This is still just a theory, and there’s a lot we don’t know about Avengers: Doomsday. But the parallels are interesting.
Doctor Doom has always been tied to massive multiversal schemes in Marvel lore. The Doomsday cast announcement strongly hints at a story that jumps across timelines and realities, which makes this kind of plan feel at least plausible within the MCU framework.
Over the course of Stranger Things Season 5, the heroes worked desperately to protect a group of children from Vecna, also known as Henry Creel and Mr. Whatsit. They eventually took the fight directly to him and managed to save the kids before the world collapsed around them. Whether Avengers: Doomsday follows a similar emotional path or flips the script entirely is still anyone’s guess.
All of this speculation will finally be put to rest when Avengers: Doomsday hits theaters on December 18, 2026.
