Tom Holland's replacement in the Marvel Cinematic Universe is Kamala Kahn.

Kamala Khan (Ms. Marvel, if you're nasty) is a fresh wide-eyed kid who is squaring up against the MCU's seasoned veterans, so move over, Spider-Man.

According to Screen Rant, Marvel needs new talent to play the role of a spirited young person attempting to find their feet in a world of gods

and monsters because Peter Parker has grown up as a result of the profound events in Spider-Man: No Way Home. Iman Vellani's Kamala fills that role.

As far as we know, Spider-Man himself won't be leaving the MCU, but he no longer plays the same part that he once did. 

In Captain America: Civil War, Spider-Man and Tom Holland, who plays him, were initially introduced to Marvel fans as newcomers to the heroic life. 

Peter Parker spent as much time admiring (pardon the pun) everyone's impressive powers and outfits as he did fighting in the infamous airport fight scene from Civil War.

Peter Parker, however, underwent significant growth over the span of three solo movies and two further Avengers movies.

By the end of No Way Home, he had lost his star-struck youth, leaving a void in the MCU's structure that Kamala Kahn must now fill.
