Tony Stark’s Greatest Fear Might Finally Play Out in Avengers: Doomsday | Comic Con 2026

The caller Avengers: Doomsday footage that was screened exclusively successful Hall H connected Saturday for attendees of San Diego Comic-Con (well, “exclusively” until it leaked everyplace connected societal media successful nary time) suggests that determination is thing that links Doctor Doom and Tony Stark beyond the information that Robert Downey Jr. plays some roles.

In the Hall H footage, Sue Storm says, "Victor was ever the smartest guy. He utilized to beryllium kind, helium utilized to beryllium caring. Everything helium loved was taken from him. He was broken." Later, Victor Von Doom says, "All of you... person stolen lives. But now, you indispensable springiness them back."

The going mentation is that by going backmost successful clip to reconstruct the Infinity Stones astatine the extremity of Avengers: Endgame, and staying successful the past, Steve Rogers unwittingly triggered a multiversal mishap that leads to the cosmic mayhem that volition play retired successful Doomsday. Specifically, that someway the Avengers’ actions caused the decease of Doom’s woman and/or daughter. Perhaps a benignant of mentation of Thanos’ Snap that wiped retired fractional of each beingness successful the universe.

Such calamity and heartbreak would surely motivate a fella, particularly 1 arsenic brilliant, driven and resourceful arsenic Victor Von Doom, and would shed much airy connected what mightiness beryllium his eventual goal. It would besides straight reflector Tony Stark’s ain top fearfulness that helium revealed successful Endgame.

You’ll callback that Tony initially rejected his teammates’ clip heist transportation precisely due to the fact that helium feared it could conceivably erase his beloved girl Morgan from ever existing.

In a deleted country that featured histrion Katherine Langford arsenic a teenage Morgan Stark, Tony appeared successful the Soulworld wherever helium confessed his fears to her, saying, “I'm frightened I made a mistake.” Tony was acrophobic that the Avengers’ clip heists and his ain Infinity Gauntlet drawback to Blip backmost each those who Thanos wiped retired could erase his beloved girl Morgan from existence. When Morgan assured him his sacrifice worked and each would beryllium good for her, Tony was capable to fto spell and walk away.

But ideate if Morgan – who was calved aft the Snap – had been erased from beingness and the lone mode Tony could bring her backmost was to marque what Doom calls successful the trailer “an unthinkable decision”? That would look to beryllium the impetus down Doctor Doom’s universe-ending plans.

Or possibly Doom conscionable wants to termination each of the Avengers and Fantastic Four’s offspring to avenge his own.

Imagine if Morgan had been erased from beingness and the lone mode Tony could bring her backmost was to marque what Doom calls “an unthinkable decision”?“

Tony Stark surely had his ain “the ends warrant the means” agendas successful the MCU (that’s however Ultron came about), truthful Doom would look to beryllium Tony’s reflector image. Whether Victor Von Doom really looks conscionable similar Tony Stark oregon is immoderate benignant of variant of him remains to beryllium seen, but for present the authoritative revelations astir Avengers: Doomsday would suggest that Tony Stark wasn’t the lone 1 who loved idiosyncratic 3000.

For much MCU sum from SDCC, work up connected Ryan Gosling’s casting arsenic Ghost Rider, David Jonsson joining Black Panther III arsenic T’Challa’s son, Kevin Feige’s pushback connected Doom not having a Thanos-level build-up, and Ryan Reynolds’ Deadpool crashing the Doomsday panel.
