New footage screened for Avengers: Doomsday at San Diego Comic-Con 2026 indicates that Doctor Doom's motivations may be deeply intertwined with Tony Stark's greatest fear, as revealed in Avengers: Endgame. The connection appears to stem from a potential tragedy that befalls Doom, mirroring Stark's own anxieties about his daughter, Morgan.
During the Hall H presentation, Sue Storm's dialogue hinted at Victor Von Doom's past: "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." Later, Doom himself is heard saying, "All of you... have stolen lives. But now, you must give them back."
A prevailing theory posits that Steve Rogers' decision to travel back in time to restore the Infinity Stones at the end of Avengers: Endgame, and his subsequent choice to remain in the past, may have inadvertently caused a multiversal incident. This event could be responsible for the cosmic chaos depicted in Doomsday, potentially including the death of Doom's wife or daughter, akin to Thanos's devastating Snap.
Such a loss would serve as a powerful motivator for a brilliant and driven individual like Victor Von Doom, aligning with his ultimate objectives and directly reflecting Tony Stark's most profound fear expressed in Endgame. Stark initially hesitated to support the Avengers' time heist precisely because he worried it could erase his daughter Morgan from existence.
A deleted scene from Endgame showed Tony Stark in the Soulworld, confessing his fears to a teenage Morgan. He expressed concern that the time heist and his own Infinity Gauntlet snap might negate Morgan's existence. Morgan's assurance that his sacrifice had protected her allowed Tony to accept his fate.
The narrative implications suggest a scenario where Morgan, born after the Snap, could have been erased. If Tony had to make "an unthinkable decision" to bring her back, this could be the driving force behind Doctor Doom's universe-ending plans. Alternatively, Doom's actions might be driven by a desire to avenge his own losses by targeting the offspring of the Avengers and Fantastic Four.
Stark himself pursued controversial "ends justify the means" agendas in the MCU, most notably leading to the creation of Ultron. This suggests Doom could be a dark reflection of Tony Stark. While it remains to be seen if Victor Von Doom will be a variant of Stark or a distinct character, the revelations from Avengers: Doomsday suggest that Tony Stark was not the only one who loved someone "3000."
