As Marvel and Sony have yet to confirm that The Shocker is even in Spider-Man: Homecoming, nothing is known about the scope of his role.
Created in 1967 by Stan Lee and John Romita Sr, The Shocker creating localized earthquake-like vibrations and emitting concussive blasts as a weapon.
Marvel Studios’ upcoming Spider-Man: Homecoming is looking to prove that isn’t a rule, by including The Vulture (Michael Keaton, presumably) as part of the film’s storyline, along with weapons-maker The Tinkerer (Michael Chernus).
Like many Spider-Man villains, Shocker is not typically a world-conqueror or a master criminal.
