How long has Tom Holland’s Peter Parker been Spider-Man in the MCU? Well according to Heroic Hollywood, Parker has been the web-slinger for little over a year prior to events in Captain America Civil War. Apparently Spider-Man is just considered a myth as well, so no one knows that he actually exists. I’m sure once Peter Parker gets his new Spidey suit, and teams up with the Avengers, people will welcome the friendly, neighborhood Spider-Man. Except for J. Jonah Jameson of course.
