Marvel's Avengers: Armageddon #4 hints at Bucky Barnes' death, fueling Avengers: Doomsday fan theories

Marvel Comics' "Avengers: Armageddon" #4 depicts Bucky Barnes being vaporized in an explosion caused by Red Hulk, fueling fan speculation that his MCU counterpart may die in "Avengers: Doomsday." The blast, triggered by gamma radiation exposure, kills civilians and Bucky, though other heroes survive. Fans theorize Sebastian Stan's schedule conflicts with "The Batman Part II" suggest his MCU exit, with his death potentially uniting heroes like Coulson's did. However, killing Bucky risks undermining his redemption arc and relationships, particularly with Sam Wilson and Steve Rogers. Stan remains enthusiastic about the role, and comic deaths rarely directly foreshadow film plots.
