Mark Ruffalo‘s Hulk could have an unexpected role in Avengers: Doomsday. However, his screen time might be more limited than fans expect. With several established heroes facing Doctor Doom, questions remain about how much room the film will give each character.
Scooper James Mack recently shared a claim about Hulk’s screen time on X. He wrote, “Mark Ruffalo’s Hulk only appears in the final battle of Avengers Doomsday.” This remains an unconfirmed rumor, as Marvel Studios has not commented on the claim. Nevertheless, the claim has raised questions about how the studio plans to develop Bruce Banner’s storyline in the upcoming crossover.
How Avengers Endgame: Encore’s post-credit scenes set up Hulk’s Doomsday role

The latest speculation comes after Avengers Endgame: Encore, which teased Banner and Doctor Doom. The post-credits sequence features an encounter that could have consequences for both characters in the next Avengers installment.
The scene takes place inside an underground government facility, where Banner records video logs documenting his attempts to suppress his transformations into the Hulk. However, Doom suddenly appears and tells him, “Mr Banner, I’ve come to collect you.”
Banner subsequently begins transforming into the Hulk, but the scene cuts away before viewers see the full confrontation. Doom’s unexpected visit suggests that he has a particular interest in Banner, although the reason behind it remains unclear.
The encounter could serve as an important setup for the two characters’ next appearance in the MCU. Doom could be interested in Banner’s scientific expertise or the Hulk’s immense strength, but the reason behind his interest remains unclear.
If the rumor is accurate, it could disappoint fans of Ruffalo’s Hulk. Rather than playing a substantial part in the story, Hulk might only appear during the final battle.
Avengers: Doomsday will release in theaters on December 18, 2026.
