Sophia Di Martino's social media activity suggests her involvement as a Latverian Witch in Avengers: Doomsday.

Sophia Di Martino, known for her role as Sylvie, recently sparked significant fan speculation regarding Avengers: Doomsday. The actor briefly liked an Instagram comment from a fan directly asking about her involvement as a "Latverian Witch," a mysterious character teased by Marvel Studios. This fleeting social media interaction, quickly reversed, has ignited conversations about her potential role in the highly anticipated film.

The brief validation, from an actor who receives countless comments, quickly became more telling in its retraction. The disappearance of the like suggests Di Martino either realized she had inadvertently revealed a secret or was instructed by production to remove it. This subtle yet impactful interaction strongly aligns with ongoing fan speculation connecting Sylvie, her character, to one of Doctor Doom’s enigmatic Latverian Witches.

The Latverian Witches first emerged as a mystery at San Diego Comic-Con 2026, where Marvel Studios showcased a series of costumes near Avengers: Doomsday props. The exhibit featured four distinct color schemes for the "Latverian Witch" attire, rotated nightly, sparking immediate fan curiosity. Despite their prominent display, these characters have remained absent from all trailers and promotional materials, with no cast or crew, including Robert Downey Jr., commenting on their identities.

The varied color schemes of the costumes have fueled extensive fan theories. A purple variant immediately suggested Clea, portrayed by Charlize Theron, due to its association with the Dark Dimension sorceress in Marvel Comics. An orange-toned version led to speculation about Elizabeth Olsen's Scarlet Witch, aligning with her signature crimson. Furthermore, leaked promotional images revealed a masked figure, nicknamed Boris, with a distinctive third-eye slot, reminiscent of Stephen Strange's transformation in Doctor Strange in the Multiverse of Madness.

The characters linked to these theories—Clea, Scarlet Witch, and Sylvie—are all powerful magic wielders with deep connections to the multiverse. Sylvie's actions in Loki directly led to the fracturing of the Sacred Timeline, while Doctor Strange, Wanda, and Clea have all navigated its complexities and dangers. Their shared history of survival and willingness to make sacrifices, often outside traditional heroic norms, positions them as compelling, if morally ambiguous, potential allies for Doctor Doom in Avengers: Doomsday.
