Peter started suiting up in a homemade costume and practicing “with great power comes great responsibility” shortly after the death of his Uncle Ben, but his hero game gets taken up a few notches when Tony Stark (Robert Downey Jr.) takes him in as part of the Stark Internship Program (which winds up suiting as a nice cover story for Peter to tell Aunt May and his friends in Spider-Man: Homecoming).
Thanks to his participation in the Leipzig-Halle Airport battle against Captain America, he has a fancy Stark-designed Spider-Man suit to work with — and as you’ll see in the new solo film, it provides him with an impressive number of cool tricks kept up his sleeve.
