Tom Holland portrays Peter Parker / Spider-Man in the Marvel Cinematic Universe (MCU), a Queens teenager bitten by a radioactive spider who gains superhuman abilities and is mentored by Tony Stark (Iron Man). His journey includes joining the Avengers, surviving the Blip, and clashing with villains like Adrian Toomes and Quentin Beck, the latter of whom publicly reveals his secret identity. To undo this, Peter enlists Doctor Strange, but the spell fractures the multiverse, bringing Tobey Maguire and Andrew Garfield's Spider-Men into his world and leading to the tragic death of his Aunt May. Ultimately, a new spell erases the world's memory of Peter Parker, forcing him to start over as a solitary hero protecting New York City. Holland's portrayal has been a critical and commercial breakout, making him a flagship MCU character across seven films as of 2026, with a return planned for Avengers: Secret Wars (2027).
