As the MCU builds its major Phase Six crossover event, the fate of some of its longest-running heroes hangs in the balance.
Sebastian Stan, who has played Bucky Barnes since 2011's Captain America: The First Avenger, recently sparked his character's rumored death regarding the Winter Soldier.
Between teasing a brutal path ahead in upcoming films and admitting the uncertain future of his presence down the line, fans are questioning how much longer Bucky really has left in the MCU.
Sebastian Stan's Unexpected Avengers: Secret Wars Update Sparks Death Rumors
While promoting his recent projects, Sebastian Stan opened up about what fans can expect from the impending multiversal clashes, directly addressing his involvement in Marvel Studios' slate.
When speaking with IndieWire, Stan shared a surprisingly ambiguous status update regarding his spot in Avengers: Secret Wars, noting that he has not yet received word or scheduling confirmation for the film:
"I know there's this other film that's meant to shoot next year, but I haven't heard anything about it," Stan revealed. "There's a lot of people waiting to see when it's going to happen. I don't know if it's on the schedule yet."
Combined with his previous comments to Decider, where he warned that Avengers: Doomsday will be "heartbreaking, in a lot of ways" where audiences will "see who makes it to the next level," the internet immediately began speculating that Bucky Barnes could be among the major casualties claimed by Doctor Doom.
How Bucky Barnes' Potential Death Changes Avengers: Secret Wars and MCU Future
Having survived World War II, decades of brainwashing as the Winter Soldier, and the trauma of the Infinity Saga, Bucky represents one of the final remaining emotional bridges that bring fans back to Phase One. Losing him would mark a tragic close to one of the originals.
After his lead role in MCU projects like Thunderbolts*, Bucky's permanent exit would leave a huge void among the non-cosmic, grounded heroes of the MCU as they face a multiversal annihilation in Doomsday, and potentially another in Secret Wars.
With Secret Wars poised to deal with heavy alternate timelines and variants, even if Bucky falls in Doomsday, the door remains open for alternate versions or emotional flashbacks for Stan to reprise his part, leaving fans to wonder if his absence is a smokescreen for a potential twist.
For now, Avengers: Doomsday premieres on December 18, 2026, with Avengers: Secret Wars slated for December 17, 2027. Stay tuned!
