Other Spider-People

Miles, Peter, and Gwen are also joined in Miles’ dimension by three other Spider-people. There’s Spider-Man Noir (Nicolas Cage), whose dimension is perpetually 1933 where he’s a private detective fighting Nazis. There’s Peni Parker (Kimiko Glenn), a young Japanese American girl from the year 3145 who has a psychic link with a radioactive spider who helps power a giant robot Peni’s dad made. Then there’s Spider-Ham (John Mulaney), a pig with the powers of Spider-Man who is from a cartoon universe where he’s a news reporter.
At the end of the film, each is sent back to their own dimension. Only Gwen, in the film’s final scene, breaks through back into Miles’s dimension.
