For Marvel to effectively position Avengers: Doomsday as a contender alongside the monumental Avengers: Infinity War, it must embrace innovative storytelling techniques, particularly in its portrayal of villains. At the center of this intrigue is Robert Downey Jr.’s role as Doctor Doom, a casting choice that has captivated audiences since it was announced during the 2024 San Diego Comic-Con. With the film set to release in 2026, anticipation continues to surge regarding its storyline, cast, and the overarching implications for the Marvel Cinematic Universe (MCU) moving forward.
One of the most compelling aspects of Avengers: Doomsday is the recasting of Downey Jr. as a villain, given his longstanding association with the heroic persona of Iron Man. Fans are eager to see how Marvel will navigate this duality and whether it can succeed in rendering Doctor Doom as a complex antagonist worthy of the franchise’s legacy. A strong strategy could involve adopting innovative narrative techniques reminiscent of how Thanos was portrayed in Infinity War.

Crafting the Complexity of Thanos



The depiction of Thanos in Avengers: Infinity War represents a significant departure from his comic book origins. Traditionally, in comics, he was portrayed as the Mad Titan with a singular obsession for Lady Death and an often unfathomable rationale for his actions. However, the MCU introduced a more relatable motivation—his tragic experience witnessing the collapse of his own home planet, Titan. This backstory added a layer of empathy to his character, transforming him into a more nuanced figure rather than a simple villain.
This reimagining culminated in Thanos becoming the narrative’s focal point. His character commanded the most screen time, 29 minutes, surpassing the Avengers and adding depth to his motivations. The film dedicated substantial time to exploring his beliefs, allowing audiences to understand the complexity behind his desire to eliminate half of all life as a misguided effort to ensure universal sustainability.

Envisioning Doctor Doom’s Central Role

Marvel has the opportunity to replicate this successful narrative strategy with Doctor Doom in Avengers: Doomsday. By positioning Doom as a central character, the film could enhance his depth similarly to Thanos. Robert Downey Jr.’s immense talent and reputation lend an additional layer of credibility to Doom’s characterization, suggesting that he will not merely be a conventional villain but a pivotal figure in the storyline.
This casting choice has ignited widespread discussion, with many speculating that Marvel would not cast an actor of Downey Jr.’s caliber only to relegate him to a minor role. There’s speculation that the opening act may heavily feature Doom, possibly engaging in complex interactions with alternate versions of Thanos or the Council of Kangs. Such a focus could elevate both the character and the film’s narrative structure.

Long-Term Impact on the MCU Beyond Doomsday

Should Marvel decide to emphasize Doom’s character, this would not only enhance his role in Avengers: Doomsday but could also lay critical groundwork for future installments, particularly Avengers: Secret Wars. Doom’s first full appearance in the MCU will set a precedent for his involvement in subsequent films, as he’ll presumably play a dominant role in the narrative arc leading to Battleworld—a concept drawn directly from Marvel’s comic lore. This would allow the audience to witness his evolution from villain to a ruler with tragic motivations, ultimately creating a character that is multifaceted and compelling.
Challenges of Centering Doom as the Main Antagonist
Issues Tied to Hero Development



Despite the advantages of making Doctor Doom a central character, this approach presents significant challenges for the Avengers team. Unlike the established character dynamics of Infinity War, the current Avengers roster is still developing during Phases 4 and 5. With only limited appearances from core heroes like Captain America and Iron Man, there’s a risk that the film may under-develop its protagonists in favor of enriching Doom’s storyline.
Moreover, many characters slated for the film will have had minimal interactions with the established MCU prior to its release. This necessitates a tightly woven narrative structure to balance screen time between Doom’s development and the heroes’ introduction, ensuring that all characters are adequately represented and that they can work cohesively as a team. The script must address these challenges effectively to mirror the success that Thanos achieved in Infinity War.
