The official title for Spider-Man 4 has finally been revealed, and it could mark the perfect MCU debut for Harry Osborn, Peter Parker's best friend.

Brand New Day teases Harry Osborn’s MCU debut, mirroring the comic's reboot. Will Peter Parker’s new ally become his greatest foe?

As Screen Rant pointed out, the comic version of Brand New Day heavily featured Harry Osborn. This has led to the belief that Osborn could be introduced in the upcoming film. However, as the theory explains, there's no shortage of controversy around Osborn, as he was brought back from the dead in the comics.
