Rumors have circulated for months about Sydney Sweeney joining the Marvel Cinematic Universe. After her appearance in the critically panned Madame Web, where she portrayed Julia Cornwall, a character destined to become Spider-Woman, many fans believe she deserves another shot at a superhero role.

Speculation intensified when scooper accounts linked her to Emma Frost in Marvel’s X-Men reboot, though Samara Weaving ultimately landed that part. Despite missing out on Emma Frost, Sweeney remains a top fan-casting choice for multiple Marvel characters. Her blend of charisma, physicality, and dramatic range makes her an ideal candidate for the MCU’s next phase.

Here are five roles that would perfectly suit the Hollywood diva.

Felicia Hardy, known as Black Cat, stands as one of Spider-Man’s most compelling allies and occasional adversaries. The character combines acrobatic prowess, expert thievery, and a morally ambiguous streak that makes her unpredictable in any storyline.

Sweeney’s portrayal of Julia Cornwall in Madame Web already positioned her within the Spider-Man universe, giving her a natural pathway to take on a similar role as Black Cat. Her ability to balance charm with danger aligns perfectly with Felicia’s personality.

The actress has shown she can deliver both vulnerability and strength, qualities essential for a character who oscillates between hero and villain. Fans have actively campaigned for Sweeney as Black Cat since the Emma Frost rumors began, citing her screen presence as an ideal match. This role would allow her to reclaim her place in superhero cinema after Madame Web underperformed.

Black Cat is not the only iconic Marvel role fans believe Sweeney could embody with ease.

Raven Darkholme, known as Mystique, represents one of Marvel’s most complex and shape-shifting villains. The character has appeared in numerous X-Men films, portrayed by Rebecca Romijn and Jennifer Lawrence, but the MCU reboot offers a chance to reimagine her entirely.

Mystique is a mutant shapeshifter who can alter her appearance, voice, and even clothing, making her a master of espionage and infiltration. Sweeney’s dramatic range, showcased in Euphoria and The White Lotus, would allow her to portray Mystique’s layered identity struggles and moral ambiguity.

Fans have actively campaigned for her to take on the role, arguing her ability to convey vulnerability and menace in equal measure makes her ideal for the character. Introducing Mystique in the MCU’s X-Men launch would provide a compelling antagonist with deep ties to the mutant narrative.

Mystique’s shapeshifting prowess is formidable, yet another Marvel character offers a different kind of spotlight.

Alison Blaire, better known as Dazzler, brings a unique blend of mutant powers and pop stardom to the X-Men roster. Her ability to convert sound waves into light-based energy attacks makes her visually spectacular on screen, while her career as a disco and pop singer adds layers of personality and conflict.

Sweeney’s recent roles in Euphoria and The Idol demonstrate her comfort portraying ambitious entertainers navigating fame and personal struggle. This experience positions her perfectly to embody Dazzler’s dual life as a performer and a mutant fighter.

The character’s introduction would coincide with the X-Men reboot, allowing Sweeney to join a fresh ensemble without the baggage of previous Spider-Verse projects. Her musical talents could even be showcased in a way that few other MCU characters allow. Dazzler’s optimism and resilience mirror qualities Sweeney has displayed in her own career trajectory.

If a mutant singer feels too niche, a classic X-Men villain could offer Sweeney a chance to explore darker territory.

Wanda Maximoff, the Scarlet Witch, remains one of the MCU’s most powerful and tragic figures, portrayed by Elizabeth Olsen since Avengers: Age of Ultron. With Olsen’s future in the franchise uncertain following Doctor Strange in the Multiverse of Madness, fans have speculated about potential successors to the role.

Sweeney’s ability to portray emotional depth and psychological complexity makes her a compelling choice to inherit the mantle of the Scarlet Witch. Her dramatic credentials would allow her to explore Wanda’s grief, power, and moral ambiguity in new ways.

While no official recasting has been announced, the idea of Sweeney stepping into the role has gained traction among fans seeking a fresh interpretation. Such a move would be bold, yet it could revitalize one of the MCU’s most iconic characters.

Julia Cornwall, the character Sweeney portrayed in Madame Web, is destined to become a version of Spider-Woman in Sony’s Spider-Man Universe. The actress already has established ties to the spider-powered corner of Marvel’s multiverse, making her a natural candidate to take on or expand that role in the MCU.

Spider-Woman, whether as Julia Carpenter or another iteration, possesses superhuman strength, agility, and venom blasts, offering a dynamic action presence. Sweeney’s performance in Madame Web demonstrated her ability to handle superhero material, despite the film’s poor reception.

Bringing her into the MCU as Spider-Woman would create continuity between Sony’s projects and Marvel’s overarching narrative. Fans have expressed enthusiasm for this possibility, noting her existing connection to the character.
