Disney Drops ‘Doomsday’ Bomb That Resets MCU Back to ‘Avengers Endgame’
For more than a decade, the MCU has prided itself on constant forward momentum. Yet Marvel Studios now seems ready to rewind the clock dramatically. With Avengers: Doomsday arriving in 2026, Disney isn’t just launching another ensemble adventure—it’s setting up a reset that drags the franchise back to the emotional core of Avengers: Endgame (2019).
The buzz around this move feels like the excitement that surrounded the Infinity War and Endgame double feature. Only this time, instead of building toward something new, Marvel is revisiting the moment that defined its golden age.
Fantastic Four and the Road Ahead
The reset comes right as Phase 6 begins. Fantastic Four: First Steps kicked things off, reintroducing Marvel’s “First Family” in a vibrant, retro-futurist style. More than just a superhero origin, it opened a door into the Multiverse that will be central to everything that follows.
Next up is Spider-Man’s fourth film, set before Doomsday. After No Way Home left Peter Parker erased from his friends’ lives, rumors swirl that the wall-crawler’s next chapter will be darker than ever. A more isolated, mature Peter—shouldering responsibility alone—would line up perfectly with Marvel’s recent tonal shift.
Shadows in the MCU
That tonal shift was already on display with Thunderbolts (2025), a story about uneasy alliances and antiheroes operating in moral gray areas. Together, the Thunderbolts’ success and Spider-Man’s rumored darker turn signal that Marvel is experimenting with stories that feel less optimistic and more complex.
But even with this experimentation, the focus keeps snapping back to Endgame. Avengers: Doomsday is shaping up to be the point where Marvel ties its future directly to its past.
Doctor Doom’s Arrival
The film is set to bring familiar faces back to the big screen. Thor, Bucky Barnes, Yelena Belova, and others are all expected to return, potentially joined by fresh names like Ryan Reynolds’ Deadpool. But the headline grabber is Robert Downey Jr., who steps back into the MCU—not as Iron Man, but as its greatest villain, Doctor Doom.
The storyline reportedly spans multiple realities, visiting the Fantastic Four’s world, the Fox-era X-Men, and more. If it sounds enormous, that’s the point. Marvel is making this one the biggest Avengers film since 2019’s Endgame.
The Leak That Changed Everything
What really has fans talking, though, is a reported set leak. Scooper UnBoxPHD revealed that Marvel has rebuilt Steve Rogers and Peggy Carter’s house—the one from Endgame’s finale—on the Doomsday set in Windsor Great Park. While no photos have surfaced, the replica looks to be a near match for the original.
That detail hints at something massive: Steve and Peggy’s quiet life together may be more than just a happy ending.
Why Their Return Matters
If Steve’s alternate timeline is revisited, it suggests his decision to stay in the past may have destabilized the Multiverse. His choice to rewrite history could place him squarely in Doctor Doom’s crosshairs, making him a key player in Doomsday.
Seeing Steve and Peggy again would also hit fans emotionally. Chris Evans’ farewell felt final in 2019, but Multiverse storytelling thrives on unfinished business. Bringing them back reminds viewers that no story in the MCU is ever truly closed.
Endgame Reimagined
Disney’s decision to revisit Endgame is more than nostalgia. It’s a chance to reshape the future of the MCU by questioning one of its most iconic endings. If Doomsday reframes Steve’s choice as a mistake with catastrophic consequences, Endgame may no longer feel like a conclusion—it could be the prologue to Marvel’s darkest chapter yet.
