Marvel Studios screened exclusive Avengers: Doomsday footage in Hall H at San Diego Comic-Con 2026 on Saturday, and while the presentation was meant to stay in the room, clips leaked across social media almost immediately. The footage suggests a narrative thread connecting Doctor Doom and Tony Stark that goes far beyond Robert Downey Jr. pulling double duty as both characters. For anyone who has followed the MCU's emotional core since Avengers: Endgame, the implications are striking: Victor Von Doom's driving tragedy may be a dark reflection of the very fear that nearly stopped Tony Stark from joining the time heist in the first place.
The leaked Hall H material centers on two key moments. Sue Storm describes Victor as someone who "used to be kind, he used to be caring" before "everything he loved was taken from him" — a backstory that positions Doom as a man broken by loss rather than born villainous. Later, Doom himself declares, "All of you... have stolen lives. But now, you must give them back." That accusation, aimed squarely at the Avengers, fuels the prevailing theory that Steve Rogers' decision to remain in the past while restoring the Infinity Stones triggered a multiversal mishap that cost Doom his wife and/or daughter. If accurate, the Avengers' victory over Thanos inadvertently authored a new catastrophe — one that gave Victor Von Doom the same motive Tony Stark once dreaded.
Doctor Doom Is Tony Stark's Nightmare
The Hall H screening gave attendees the first substantial look at how Avengers: Doomsday plans to frame its antagonist. Sue Storm's testimony — "Victor was always the smartest guy. He used to be kind, he used to be caring. Everything he loved was taken from him. He was broken." — reframes Doom not as a conqueror by nature but as a grief-stricken genius lashing out at the universe that wronged him. That characterization aligns with the trailer line where Doom references an "unthinkable decision," suggesting his multiversal campaign stems from personal loss rather than abstract ambition. The footage stops short of confirming exactly what was taken, but the timeline implications point toward the Avengers' Endgame time heist as the catalyst.
"All of you... have stolen lives. But now, you must give them back"
Doctor Doom
Doom’s opening line cuts straight to the chase, both pointing fingers and laying out a mission. It hints that the Avengers, as a collective, are to blame for a disaster that could rival the magnitude of Thanos’ Snap—perhaps a narrow wipeout triggered by the divergent timelines Steve Rogers set into motion when he kept the stones. Players following the MCU saga will see this the same way Tony Stark feared: that messing with time could erase the ones he loves most. The connection goes beyond plot; both heroes are driven by an intense need to protect family, and they’re ready to twist reality itself to keep those loved ones safe.
Doctor Doom: Stark's Secret Nightmare Made Real
Tony Stark's hesitation in Avengers: Endgame was never about doubt in the science — it was about Morgan. He initially rejected the time heist pitch because he feared the ripple effects could erase his daughter, who was born after the Snap, from ever existing. A deleted scene with Katherine Langford as a teenage Morgan Stark made this explicit: Tony appears in the Soulworld and confesses, "I'm scared I made a mistake." Morgan reassures him the sacrifice worked, allowing Tony to pass peacefully. But the Avengers: Doomsday footage invites a haunting what-if: what if Morgan had been erased, and the only way to restore her required the "unthinkable decision" Doom now pursues? That scenario would make Victor Von Doom a literal mirror of Tony Stark — same face, same intellect, same love, same willingness to break the world to save one person.
The comparison extends beyond grief. Tony's "ends justify the means" mindset birthed Ultron, a catastrophe born from trying to preemptively save humanity. Doom appears to be following that same logic: if the Avengers' actions stole his family, then dismantling their reality to reclaim them is justified. Whether Doom is a Stark variant or simply a man who arrived at the same philosophical extreme remains unconfirmed, but the Hall H footage strongly suggests Marvel is positioning him as Tony's dark reflection — the version of Tony who didn't get the reassurance from Morgan, who didn't get to let go. As the footage implies, Tony Stark wasn't the only one who loved someone 3000.
Additional SDCC 2026 reveals include:
- Ryan Gosling cast as Ghost Rider
- David Jonsson joining Black Panther III as T'Challa's son
- Kevin Feige pushed back on criticism that Doom lacks Thanos-level build-up
