Black Swan will make her MCU debut soon.
According to insider James Mack, who leaks major plot details of Avengers: Doomsday, Marvel Studios is considering introducing Black Swan in Doctor Strange 3 as a supporting character.

Black Swan is an important character in the Secret Wars storyline from the comics and could also appear in Avengers: Secret Wars. The character was first introduced in New Avengers (2013) by Jonathan Hickman, which directly sets up the Secret Wars storyline. She is one of the first characters to explain and witness “incursions” — the catastrophic collisions of parallel Earths in the multiverse.
As we reported, Doctor Strange (Benedict Cumberbatch) and Clea (Charlize Theron) are currently in the Dark Dimension, as seen in the Doctor Strange in the Multiverse of Madness post‑credits scene.
By the time Avengers: Doomsday takes place, Doctor Strange will have been missing from Earth‑616 for two years. Strange’s sudden disappearance creates suspense, and he has not informed Wong of his whereabouts.

Marvel is planning to adapt elements from the Time Runs Out comic event for Doctor Strange 3. Black Swan also plays a major role in both the Incursions and Time Runs Out storylines.
According to rumors, the plot will continue from Doctor Strange in the Multiverse of Madness, where Clea arrives from another dimension seeking Strange’s help to fix an incursion he caused. In the comics, Clea is part of the multiversal group known as the Black Priests, who operate in the “Nothing Space” of destroyed universes — a group formed from two dead universes caused by an incursion.
The film is expected to define the dying Multiverse as a result of ongoing incursions, including those triggered by Doctor Strange’s actions, and explore his growing threat to the Multiverse, as revealed in Multiverse of Madness.
