‘Avengers: Doomsday’s’ SDCC Booth Just Revealed a Mysterious New Witch, and Fans Think They Know Who She Is
San Diego Comic Con has always been one of Marvel’s biggest playgrounds for teasing what comes next, and this year’s convention floor has already delivered one of the most talked-about reveals of the entire weekend. With ‘Avengers: Doomsday’ still five months from release, the studio’s booth has become a treasure trove of clues for fans desperate to piece together the film’s biggest secrets.
That excitement reached a new peak when Marvel’s exhibit revealed a costume unlike anything fans had seen before, tucked in among more familiar faces like Yelena, Cyclops and Gambit. The character’s design immediately sparked a wave of theories that has spread across social media within hours of the first photos surfacing.
A costume displayed at the Marvel Studios booth for San Diego Comic Con has ignited debate about a mysterious new character being called the Latverian Witch. Marvel exhibited the outfit alongside other ‘Doomsday’ props, giving convention attendees a first glimpse at a figure that has never appeared on screen in any previous MCU project.
The design itself borrows heavily from Doctor Doom’s own visual language. The costume features green robes flowing from shoulder to floor, fastened with metallic clasps, paired with a hood draping over a silver face mask that strips back much of the ornamentation seen on Doom’s own facial covering, instead sculpting more defined lips at the base. A green belt cinches the waist, its buckle featuring a silver diamond motif whose meaning has not yet been explained.
That striking visual similarity to Doom has fueled the most popular theory circulating online, with fans and outlets alike speculating this could actually be a variant version of Elizabeth Olsen’s Scarlet Witch, reimagined with Latverian roots rather than her usual Sokovian origins. Marvel had already revealed a Doctor Doom action figure featuring plastic attachments resembling red tinted magic, adding fuel to speculation about a possible partnership between Doom and a version of Wanda Maximoff.
Other rumors circulating separately suggest an entirely different backstory, with some insiders claiming Doom will be reimagined in the film as a family man, positioning the Latverian Witch as his wife rather than an ally or servant. Under that theory, her early death within the story could serve as the emotional catalyst that shatters Doom’s composure and drives his destructive rampage across the multiverse.
The costume was not the only ‘Doomsday’ related surprise on display at the booth this weekend. Marvel’s exhibit also featured a giant Sentinel head as a photo opportunity, alongside a section themed to Xavier’s School for Gifted Youngsters and merchandise tied to the film’s massive X-Men presence.
This kind of ambitious crossover scale fits the film’s overall scope, which brings together the Avengers, X-Men and Fantastic Four in what stands as the MCU’s most expansive team up to date. With Robert Downey Jr. leading the ensemble as Victor Von Doom, the film’s cast already includes nearly three dozen major Marvel stars pulled from across multiple franchises and eras.
Who do you think the Latverian Witch really is in Avengers: Doomsday?
With official confirmation of the Latverian Witch’s true identity still absent, this SDCC reveal has only intensified fan speculation heading into Marvel’s Hall H panel later this weekend, where further details about the film could finally emerge. Given how quickly this single costume has generated theories, it seems clear Marvel has succeeded in making this particular mystery one of the weekend’s biggest talking points.
