Robert Downey Jr.’s Iron Man makes his Marvel Cinematic Universe return in a Spider-Man 4 theory, and if it turns out to be accurate, Marvel Studios would have one of the franchise’s most emotional projects on its hands. Marvel’s slate of projects includes several exciting movies and series, with entries like The Fantastic Four, the next two Avengers movies, and Spider-Man 4 drawing the most attention. Given how Tom Holland’s first MCU Spider-Man trilogy is among the franchise’s best, it makes sense that anticipation is high for the return of his version of Peter Parker.
Every single one of Holland’s Spider-Man movies has featured a major role for an MCU character. That is part of the deal Sony and Marvel Studios made so that Holland’s Spider-Man could be part of the MCU while Sony still holds the character’s movie rights. Spider-Man: Homecoming featured Robert Downey
Jr.’s Iron Man as Peter Parker’s mentor, continuing their relationship from Captain America: Civil War. Due to the hero’s death in Avengers: Endgame, Tony Stark was missing from Holland’s other Spider-Man movies. However, an MCU theory shows the perfect way for Iron Man to be part of Spider-Man 4’s story.
