Zendaya's MJ could make her return in Spider-Man 4 with a twist, portraying a Spider-Man-like hero in the Marvel Cinematic Universe movie. MJ has been a fixture of the MCU's Spider-Man movies, appearing in all three entries of Tom Holland's Marvel franchise. Despite the character's importance, it seemed like Spider-Man: No Way Home had closed the door on Zendaya playing MJ in Spider-Man 4. In the movie's ending, MJ and the rest of the world forget who Peter Parker was due to Doctor Strange's spell, and Holland's character decides not to tell her the truth in order to protect her.
