Leaked promotional images from *Avengers: Doomsday* reveal Doctor Strange as Doctor Doom's sidekick 'Boris', marking a significant shift in his character arc.12

The images showcase Strange in a new suit, suggesting a dark alliance with Doom, who is portrayed as a master of sorcery and technology.6

According to sources, Strange becomes convinced that the Avengers cannot stop the multiversal collapse, leading him to accept Doom's plan for total control over magic. “He serves as the executor of Doom’s plan, manipulating incursions and controlling the TVA,” a report states.4

The leaked images also highlight the costumes of the Latverian Witches, previously featured at the SDCC Marvel booth, with speculation pointing to characters like Clea, Sylvie, and the Scarlet Witch.5

The film, directed by Anthony and Joe Russo, is set to release on December 18, 2026, and promises a complex narrative involving Strange's loyalty to Doom, reminiscent of comic storylines where he aided Doom in saving the multiverse.7

As the plot unfolds, fans are left to ponder the implications of Strange's transformation and the fate of the Avengers amidst the looming threat of multiversal incursions.

“The presence of a third eye on his mask may be telling,” hints at a darker path for the former Sorcerer Supreme.

With the film's release still years away, anticipation builds as more details emerge, keeping fans engaged in the evolving Marvel narrative.

Alex Perez: There’s no specific reason outside the possibility of wanting to keep some characters secret. And you’d think that even with all the plot leaks and everything people keep talking about, the cat’s out of the bag. But the truth of the matter is there is a lot that isn’t really out there yet for *Avengers: Doomsday* regarding specific details, characters, or motivations. There are still some characters that are surprises for *Doomsday*, mainly around the third act.”
