Speculation is growing around Sadie Sink’s mystery role in Spider-Man: Brand New Day after a reported merchandise leak surfaced online.
Sink, known for her role in Stranger Things, was previously confirmed as part of the film’s cast. However, Marvel has not revealed her character.
The latest rumours began after images allegedly linked to film merchandise appeared online.
The visuals reportedly show a red-haired character with pink energy effects around the eyes and hands.
These details have led many fans to speculate that Sink could be playing Jean Grey.
Jean Grey is one of the most iconic characters from the X-Men universe.
The theory has circulated for months, but the alleged leak has intensified discussion among fans.
Some viewers also claim that footage from the film suggests Sink’s character may have telekinetic-style abilities.
Others pointed to costume colour hints, noting yellow elements often associated with Jean Grey in the comics.
Despite the growing speculation, neither Marvel Studios nor Sony Pictures has confirmed her role.
For now, Sink’s character remains officially undisclosed ahead of the film’s release on July 31, 2026.
