For the uninitiated, Miles Morales is a black Latino Brooklyn teen who becomes Spider-Man in the Ultimate Marvel imprint of Marvel Comics, first appearing in 2011. This is as opposed to the Peter Parker Spider-Man most fans know. Miles is voiced in the movie by Shameik Moore (“Dope,” “The Get Down”) as a gifted student who’s more interested in his street art than school. After Miles is bitten by a radioactive spider (don’t you just hate when that happens?), he meets Spider-heroes from other dimensions in the Marvel Comics “multiverse.” These include the teen Spider-Gwen/Spider-Woman, a manga-inspired version pairing a schoolgirl with a spider-robot, and a film-noir-inspired iteration, a cartoon pig and two Peter Parkers.
