SPOILER WARNING: This article contains minor spoilers for Spider-Man: Homecoming, in theaters now.

Some of the more cinematically-neglected members of Spider-Man's rogues gallery -- Vulture (Michael Keaton), Shocker (Bokeem Woodbine) and Tinkerer (Michael Chernus) -- feature prominently in Spider-Man: Homecoming. However, there's another longtime villain who makes his theatrical debut in the film: MacDonald "Mac" Gargan, also known as Scorpion.

Gargan, who is played by Michael Mando, appears buying weapons on the Staten Island Ferry from Adrian Toomes before getting knocked overboard during an encounter with Spider-Man. The villain is imprisoned at some point after the encounter and shows up again in the film's mid-credits scene, bearing a scorpion tattoo and vowing revenge on the wall-crawler.

Gargan has been a long-time member of Spider-Man's rogues gallery, first appearing in 1964's Amazing Spider-Man #19 before undergoing a transformation at the behest of J. Jonah Jameson that turns him into the villain Scorpion in the next issue. The character eventually went on to bond with the symbiote and become Venom.

Marvel Studios President Kevin Feige intuited in an interview back in June that future films might be looking at villains never-before-seen in any of Spider-Man's other cinematic outings, so it seems likely that Mando will return in some capacity for the sequel to Spider-Man: Homecoming, which is due out in 2019.
