This would not only mark an exciting entry for Sink but also pave the way for a crossover between the X-Men and Spider-Man universes.
Jean Grey, one of the most iconic mutants in Marvel Comics, is known for her powerful telepathic and telekinetic abilities. If Sink takes on this role, it will be a landmark moment in the MCU, as it will mark the introduction of mutants into the universe—a highly anticipated development for Marvel fans.
