For a sneak peek at Robert Downey Jr.’s transformation into Doctor Doom, you can watch the official production announcement below:
In the upcoming MCU film Avengers: Secret Wars (2027), Doctor Doom is expected to play a pivotal role by leveraging the Sentry’s immense power to reshape reality itself. This aligns with his portrayal in Avengers: Doomsday (2026), where he manipulates the Sentry’s darker persona, the Void, to serve his agenda.

Doctor Doom’s Plan Involving the Sentry
Drawing inspiration from the 2015 comic storyline Secret Wars, where Doctor Doom usurps the power of the Beyonders to create a new Battleworld, the MCU adaptation is likely to follow a similar trajectory. In this narrative, Doom seeks to harness the Sentry’s reality-warping abilities to construct a new multiverse under his dominion. The Sentry’s darker half, the Void, is particularly crucial, as its connection to the Void dimension enables it to manipulate reality on a cosmic scale. (Doctor Doom – Wikipedia, What if Sentry is the stand in for Molecule Man in Secret Wars?)
A fan theory suggests that Doctor Doom might convince the Void to join his cause, using its power to warp reality and create Battleworld—a patchwork planet composed of fragments from various universes. This would position Doom as the central authority, with the Sentry’s abilities facilitating the reconstruction of the multiverse according to his vision. (What if Sentry is the stand in for Molecule Man in Secret Wars?)
The Sentry’s Role and Potential Conflicts
The Sentry, portrayed by Lewis Pullman, is depicted as one of the most powerful beings in the MCU, potentially surpassing all Avengers in strength. His immense power raises questions about how the narrative will address potential conflicts between him and Doctor Doom, especially considering Doom’s manipulative nature. It’s anticipated that the film will explore the dynamics between these two formidable characters, possibly leading to alliances and betrayals that could significantly impact the multiverse. (Avengers: Doomsday)
As the release of Avengers: Secret Wars approaches, more details are expected to emerge, shedding light on the intricate relationship between Doctor Doom and the Sentry, and how their interactions will shape the future of the MCU.
