Sadie Sink finally appeared on a new Spider-Man: Brand New Day poster. Even one week out from Brand New Day's July 31 theatrical release, Marvel Studios is still keeping its cards close to its chest with regard to Sadie Sink's MCU debut. The 24-year-old rising star is one of the top-billed stars in the long-awaited Spider-Man: No Way Home follow-up, and yet fans still only have theories and rumors to go off when it comes to the identity of her mystery, mind-controlling villain. 

Marvel Studios dropped a new poster to celebrate Spider-Man: Brand New Day's release in Chinese markets, featuring the web-slinger alongside the Hulk, M.J., Punisher, Scorpion, the Hand, and Sadie Sink's mystery character. The Asian-targeted poster marks the Stranger Things veteran's first appearance on an MCU poster, even though her face is obscured under a hood.

The marketing development comes as rumors heat up that Sink may lead the MCU's third saga and X-Men reboot movie as Jean Grey after she enters the fray with Brand New Day. If that is the case, this is bound to be the first of many Marvel Studios posters that center around Sink, although it ought to be one of the few that mask her face.

Beyond keeping Sink's identity a secret until Brand New Day hits theaters, Marvel Studios also omitted the Stranger Things breakout's face from every trailer, hiding her face under an ominous hood and mask.

Recent comments from Tom Holland indicated that Sink won't be unmasked until the "third act," perhaps after masterminding the movie's villainous plot from the shadows.

The only other shots of Sink's character are her restrained in a room surrounded by glass in some sort of facility.

Perhaps this is a tease that Sink is under the control or influence of another villain, who is truly behind the events of Brand New Day.

Alternatively, these restraints may be Jean's own doing. Perhaps her powers are on the fritz, and she is unable to get them fully under control, forcing her to hold herself back to prevent too much harm.

Sadie Sink's MCU Reign Is Only Just Starting With Spider-Man: Brand New Day

Marvel Studios' decision to omit the identity of Sadie Sink's character from Spider-Man: Brand New Day's marketing is a clever gambit to replicate the mystery that helped drive No Way Home's box office to new heights. However, it seems rather strange to keep the actress' recognizable face out of the posters and trailers, given that it would hardly offer any indication of her Marvel icon's identity. 

As almost everyone will be aware by now, the prevailing theory is that Sink is playing Jean Grey and that Brand New Day will tee her up for a return in Avengers: Secret Wars and a much larger role in the next iteration of the X-Men. With Tramell Tillman rumored to play the anti-mutant villain William Metzger in Brand New Day, the looming MCU flick may be a vital prequel to the X-Men reboot. 

It seems increasingly likely that Jean Grey is Brand New Day's main villain, a major shift from her usual heroic nature. Typically, Jean starts off in the comics as a hero, with her villainous Dark Phoenix persona emerging only after she has firmly been established.

However, Marvel Studios probably won't introduce its next leading superhero as an outright villain, meaning she may instead be introduced as a young mutant who has yet to grasp control of her powers, something that the next Charles Xavier will one day help her gain.

Under a week before Brand New Day's release is San Diego Comic-Con, where many are hopeful to see the MCU's X-Men cast unveiled, finally ending years of rumors. If Sink is Jean Grey, she would be a crucial part of that announcement, so Marvel Studios may hold the news until August's D23 Expo, once Spider-Man 4's biggest secrets are revealed.
