Fresh leaks surrounding Spider-Man: Brand New Day have reignited speculation about the mystery role of Sadie Sink.
Reports suggest leaked promotional merchandise may hint that Sink is playing Jean Grey, one of the most powerful mutants in the X-Men universe.
Fans point to the figure’s red-haired appearance and pink energy effects, which closely resemble Jean Grey’s signature powers.
The speculation has intensified following another alleged trailer leak, adding to growing excitement around the film.
Neither Marvel Studios nor Sony Pictures has confirmed Sink’s character, keeping details tightly under wraps.
If the rumours prove true, the film could mark a major step toward introducing more mutant characters into the Marvel Cinematic Universe.
Spider-Man: Brand New Day, starring Tom Holland, is scheduled to arrive in theatres on July 31, 2026.
