AceShowbiz - Marvel Studios showcased a costume labeled 'Latverian Witch' at their San Diego Comic-Con 2026 booth, displayed alongside props from Avengers: Doomsday. The exhibit featured four different color variants of the costume, which were rotated each night throughout the convention weekend, sparking fresh speculation about new characters in the film.

The 'Latverian Witch' costumes have not appeared in any trailers or official promotional materials for Avengers: Doomsday so far, and the identity of these characters remains unconfirmed. Fans have connected the Latverian Witches to Robert Downey Jr.’s Doctor Doom, theorizing they may be his magical followers. The costume colors themselves have fueled fan theories: a purple outfit recalls Clea, a sorceress introduced in Doctor Strange in the Multiverse of Madness, while an orange version draws comparisons to Scarlet Witch’s signature hues. Leaked images have also teased a masked figure nicknamed Boris, whose mask includes a circular slot on the forehead reminiscent of the third eye from Doctor Strange’s lore.

Sophia Di Martino, who portrays Sylvie in the Disney+ series Loki, briefly engaged with fan speculation by liking, then removing her like on an Instagram comment mentioning the Latverian Witch. She also posted and deleted a cryptic Instagram story, which, combined with sightings of her stunt double near Avengers: Doomsday filming locations in London, has fueled rumors of her possible return in the film. Sylvie is known as a powerful multiverse traveler who played a pivotal role in breaking the Sacred Timeline, making her a natural fit for the film’s expanding multiversal themes.

Avengers: Doomsday, directed by Joe and Anthony Russo and produced by Marvel Studios, is set for release on December 18, 2026. The film stars Robert Downey Jr. alongside Joseph Quinn, Pedro Pascal, Ebon Moss-Bachrach, and Vanessa Kirby, and promises to explore multiversal chaos, revisiting locations like The Void first introduced in Loki. While Sylvie’s return remains unconfirmed, the film’s ensemble includes characters from across Marvel’s expanding universe, including the Fox X-Men and Fantastic Four franchises.

The appearance of the Latverian Witch costume hints at new magical elements and alliances within Avengers: Doomsday, potentially deepening Doctor Doom’s role and introducing powerful sorceresses who could shift the stakes. With multiverse mayhem central to the story, these new characters may be key players in shaping the future of the MCU’s next big chapter.
