A teenager and Avenger who received spider-like abilities after being bitten by a genetically-modified spider. Director Jon Watts said that in contrast to Spider-Man: Homecoming, in which Parker longs for the responsibilities of an adult, in Far From Home, he wants to hang onto his youth, saying, "This film is about the world telling him, 'It's time for you to step up and grow up, kid,' and he's saying, 'But I still want to be a kid and go on vacation.'"

Parker's best friend.

A Skrull hired by Nick Fury to impersonate himself, the former director of S.H.I.E.L.D. Watts describes Fury's relationship with Parker as "the mean new stepdad", contrasting his role with Tony Stark's "supportive cool uncle" in Homecoming, saying, "Fury doesn't see himself in Peter Parker. Fury sees Peter Parker as an asset that he needs who is too preoccupied with a bunch of high school problems." Watts originally pitched Homecoming using Fury as a mentor to Parker. Far From Home puts Fury in a situation in which he does not have the same level of control he is used to having.[9] Ben Mendelsohn portrays Talos without disguise in the post-credits scene, reprising his role from Captain Marvel; Jackson also portrays the real Nick Fury in the post-credits scene.

Regarding Beck's relationship with Parker, Watts says that "If Tony Stark was sort of the mentor in the previous films, we thought it would be interesting to play Mysterio as almost like the cool uncle." Having Beck team up with Fury and Parker to take on a global threat was "really exciting" to Watts, who wanted to bring the character into the MCU "in a way that people weren't expecting."
