Sebastian Stan's Future Roles and Theories About His Character's Fate
January 7, 2026
The rumor that Sebastian Stan might star in The Batman Part 2 has sparked a frenzy among superhero fans, leading to wild theories about his character possibly dying in the upcoming Avengers: Doomsday. Known for his role as Bucky Barnes, aka the Winter Soldier, in the Marvel Cinematic Universe (MCU) since Captain America: The First Avenger over 15 years ago, Stan’s latest casting news has caused a ripple across fan communities.
From Marvel to DC: A Surprising Casting
According to early reports, Sebastian Stan may take on the role of Harvey Dent, also known as Two-Face, in The Batman Part 2. This potential move from Marvel to DC has prompted fans to connect the dots, speculating about what this means for his Marvel character.
Fan Theories and Predictions
Many fans believe that Stan’s involvement in The Batman Part 2 could mean Bucky's death in Avengers: Doomsday—a major Marvel film scheduled around the same timeframe. The reasoning is rooted in scheduling conflicts; fans argue that Stan can't appear in both universes simultaneously, so Bucky might have a sacrificial end in Marvel to allow him to portray Two-Face.
“Sebastian Stan being in The Batman means Bucky is gonna die in Doomsday,” one fan stated, highlighting the popular theory.
Another fan humorously commented:
“Sometimes you gotta lose some (Bucky Barnes dying in Doomsday) to win some (Sebastian Stan in The Batman).”
Opportunities for a New Performance
Some supporters see this role as an exciting opportunity for Stan to showcase his range as an actor. “Sebastian Stan clocking out for the last time as Bucky, who dies saving Steve Rogers, and finally getting to play a new hero in The Batman 2,” explained a fan.
Concerns and Frustration Among Fans
However, not all reactions are positive. Many Stan fans express disappointment or frustration over the potential death of Bucky. One fan shared:
“Being excited for Sebastian Stan to join The Batman II but realizing that means Bucky is so dead in Doomsday,” expressing their sadness.
Others took their concerns directly to Marvel leadership. One tweet addressed Kevin Feige:
“If Sebastian Stan playing Harvey Dent means Doomsday is his last Marvel movie... I swear to god @KevFeige.”
Despite the uncertainty, fans remain eager to see Stan's performances in both the Marvel and DC universes.
