Spider-Man: Brand New Day, starring Tom Holland, opened in theaters with what IGN reports as the biggest domestic opening day of all time, surpassing the previous record held by Avengers: Endgame.
According to Polygon, the film also features a major plot element tied to the MCU's growing X-Men storyline: Sadie Sink appears as Jean Grey, displaying both telepathy and telekinesis as she learns to control her powers.
Polygon reports that Bruce Banner (Mark Ruffalo) wears a device that suppresses the Hulk, allowing him to live normally. When Peter Parker's Spider-Man powers begin intensifying due to stress, he and Banner discuss creating a universal inhibitor capable of suppressing any super-powered individual's abilities, with both men's conditions repeatedly described as a 'mutation' during the conversation.
Per Polygon, Spider-Man later uses a version of this inhibitor in a fight with Jean Grey to stop her from using mind control, raising ethical questions in the film about which parts of a person's identity are right to suppress. Jean reportedly describes the device as taking away part of who she is, while Banner questions the morality of suppressing abilities at all.
Polygon notes that the neck-worn inhibitor resembles the mutant-suppressing collars long featured in X-Men comics, cartoons, and Fox's X-Men films, suggesting the device could become a tool used against mutants in future MCU stories—despite Jean Grey destroying one in this film. The outlet raises the question of whether it will matter that Banner and Parker, both traditionally allied with the X-Men, helped create the technology.
IGN's report does not include additional details beyond the record-breaking opening day claim, as the rest of its article was inaccessible for this summary.
