San Diego Comic-Con 2026 has kicked off, and it's already brought with it some interesting details about Avengers: Doomsday. On the opening preview night, the costumes for the upcoming Marvel movie were on display, including a character that we are yet to meet.
As you can see from the image below, one of the costumes is for a "Latverian Witch". This looks very similar to what we've seen of Doctor Doom's costume so far, complete with another distinctive mask.
We've not seen this character in any of the promotion for Avengers: Doomsday yet. She didn't appear in the recently released trailer nor has she been announced as part of the cast. As you might imagine then, Marvel fans have been having a field day speculating about who she might be.
Posting on Reddit, several fans think this could spell the return of Wanda Maximoff, the MCU's most well known witch. This has been fuelled by a comic book run called Avengers: The Children's Crusade where Doctor Doom kidnaps Wanda.
"The first thing I thought of when I saw the costume and the word 'witch' was Wanda from that Children’s Crusade comic," wrote one, while another suggested: "Perhaps even a secret Scarlet one? (Wishful thinking)."
Others have wondered if this may finally be how Clea is reintroduced after Charlize Theron's character made a brief appearance in Doctor Strange in the Multiverse of Madness post-credits scene. "It might be Clea - seen some theories that her and Strange actually end up helping Doom," wrote another.
Others have been wondering whether the witch may actually be Doom's mother, who does seem to be a part of the poster and was mentioned during the pop-up a few months ago. "Could also be Doom's mother, his first love Valeria (not Richards), Morgan Le Fey (maybe renamed) or Lady Victorius as well. Will wait and see. Of course I'd love if it were Wanda, but not gonna get my hopes up," another theory suggested.
Avengers: Doomsday arrives in theaters on December 18, 2026. For more check out our guides to upcoming Marvel movies and shows as well as how to watch the Marvel movies in order.
