The Marvel Cinematic Universe's new generation Jean Grey, portrayed by Sadie Sink, made her highly anticipated debut last month in "Spider-Man: Brand New Day," earning widespread acclaim and captivating countless fans. This pivotal appearance has laid a solid foundation for the upcoming "X-Men" film. It appears this character introduction strategy is set to become a frequent occurrence, as recent reports indicate that Jean Grey will not be the only X-Men member to first appear in other Marvel films.

Renowned entertainment journalist Matt Belloni recently revealed on his podcast, "The Town," that the multi-picture deals signed by the new "X-Men" cast not only commit them to multiple "X-Men" sequels but also include appearances in other Marvel projects. For instance, Storm has long been rumored to appear in the third "Black Panther" installment.
Belloni further teased that "Avengers: Doomsday," "Avengers: Secret Wars," and the upcoming "Ghost Rider" reboot are also slated to introduce additional new "X-Men" characters. This strategic rollout aims to build significant anticipation and popularity for these mutants across the MCU, ensuring that when they finally assemble for their first dedicated "X-Men" film, their collective impact will rival the original Avengers' monumental debut.
