This ominous plot thread has come to light following the recent theatrical re-release of the 2019 cinematic milestone Avengers: Endgame, titled Avengers: Endgame Encore. The newly surfaced version of the film features additional post-credits and connective footage that directly bridges the gap toward the events of Avengers: Doomsday. Among the most striking additions is a scene featuring Bruce Banner recording a desperate video message from deep within a secure, isolated bunker. Banner had retreated into self-imposed seclusion following the dramatic fallout of Spider-Man: Brand New Day. However, his quiet moment of isolation is abruptly and violently interrupted when Doctor Victor Von Doom suddenly materializes in the bunker and seemingly abducts the brilliant scientist. While the exact motives driving Doom remain shrouded in mystery, it is already becoming abundantly clear that his grand design extends far beyond simply capturing the Incredible Hulk.
Speaking in a recent interview with Empire, co-director Joe Russo offered tantalizing hints regarding the true scale of the villain’s ambitions, suggesting that Banner is merely a single chess piece in a much larger, more insidious scheme orchestrated by Doom. "I mean, look, his interest may extend beyond just Banner," Russo told the publication when discussing the shocking sequence, adding with a deliberate sense of caution, "So, that’s what we’ll say about that."

Russo’s vague yet ominous comments align closely with other recent cinematic hints, giving fans plenty of material to speculate on regarding who else might be squarely in Doctor Doom’s crosshairs. During the post-credits sequence of The Fantastic Four: First Steps, Doom makes a chilling appearance inside the living room of the Baxter Building, where he is seen engaged in a quiet conversation with a young Franklin Richards. Although Sue Storm abruptly enters the room and interrupts the tense encounter, it remains entirely ambiguous whether Doom successfully managed to abduct the extraordinarily powerful child or if he was ultimately forced to retreat empty-handed.
For months, a prominent and long-running fan theory surrounding the film has speculated that Doctor Doom might be targeting the children of various powerful Marvel heroes. Alongside Franklin Richards, this theory has frequently pointed toward Thor’s adopted child and, previously, the child of Steve Rogers and Peggy Carter. However, the credibility of the latter possibility took a significant hit following the revelations and narrative developments presented at the conclusion of Avengers: Endgame Encore.
Regardless of the specifics surrounding the rumored child abductions, the overarching picture emerging from these interconnected releases is that Doctor Doom is executing a calculated strategy to capture, isolate, and potentially manipulate some of the most formidable entities within the Marvel universe. With roughly two months remaining until the global theatrical premiere of Avengers: Doomsday, audiences are eagerly anticipating the answers and clarity that the film will inevitably bring to these compelling plot threads. Even so, Marvel Studios is unlikely to lay all its cards on the table just yet, as the narrative threads involving Doctor Doom are scheduled to continue unraveling further next year with the release of the massive crossover event Avengers: Secret Wars.
