Spider-Man: Brand New Day Trailer Confirms Sadie Sink as Jean Grey, Mark Ruffalo's Hulk as Primary Antagonist

A second trailer for Spider-Man: Brand New Day has been released, providing more detailed glimpses into Tom Holland's fourth solo MCU adventure. The trailer confirms that Mark Ruffalo's Hulk will be the primary antagonist facing Spider-Man, with the character appearing to be under some form of external control during their confrontation.

The trailer has substantially bolstered theories that Sadie Sink is portraying Jean Grey, the iconic X-Men character. Although Sink remains largely obscured in the footage—appearing mostly in a hoodie and speaking through other characters via apparent mind control—dialogue and visual cues strongly suggest she is playing a psychic character. In one notable moment, the character tells Spider-Man through a proxy, "You're the only person I can't jump into," implying Peter's unique biology makes him immune to her telepathic powers. The character is shown taking control of multiple civilians and appears to force Banner to transform into the Hulk, triggering the film's major action sequence.

While the trailer frames Jean as a potential supervillain, analysts suggest Marvel may be intentionally misdirecting audiences. This version of Jean Grey appears to operate independently from the X-Men and Charles Xavier, suggesting she may be a misunderstood fugitive struggling with her newly manifested psychic abilities rather than a traditional villain. The introduction of this core X-Men character in a Spider-Man film rather than a dedicated X-Men project raises questions about her ultimate role in the MCU's broader narrative, particularly given the planned X-Men reboot scheduled after Avengers: Secret Wars.

The film is also confirmed to feature other villains including Michael Mando's Scorpion, Marvin Jones III's Tombstone, and Boomerang, though they are de-emphasized in promotional materials compared to the focus on Jean and the Hulk conflict.
