Marvel’s MCU is introducing Sadie Sink’s Jean Grey as a markedly different character from earlier comic, film and animated versions: a fugitive whose powers and actions initially make her appear to be Spider-Man’s enemy. The article argues this unconventional debut in Spider-Man: Brand New Day is promising because it signals that Marvel intends to reinvent the X-Men rather than simply repeat familiar origin stories, while beginning the transition away from Fox’s long-running cast.

Jean attacks Department of Damage Control sites and possesses figures including Scorpion and Hulk while trying to rescue her captive sister, Sara. After learning that Jean is a victim rather than a straightforward villain, Peter Parker prevents her from destroying much of New York; Jean helps save his life and leaves for what is implied to be Xavier’s school. This contrasts with the traditional portrayal of Jean as Professor X’s protected early student and a founding X-Man, suggesting a new team with a less conventional history.
