After the Battle of New York, Adrian Toomes and his company are contracted to clean up the city, but the operation is taken over by Tony Stark’s Damage Control Department (DCP). Angry that he was taken out of business, Toomes persuades his employees to keep the Chitauri technology they have already recovered and to use to conceive and sell advanced weapons. Eight years later, Peter Parker is co-opted in Avengers by Stark to help an internal dispute, but he returns to school when Stark tells him he’s not yet ready to become Avenger.
Parker drops out of the decathlon high school team to focus more on his crime fighting activities as Spider-Man. One night, after stopping criminals from robbing an ATM using their advanced weapons they purchased from Toomes, Parker returns to his apartment in Queens where his best friend, Ned, discovers them the secret identity.
One night, Parker gives over to Toomes, Jackson Brice / Shocker and Herman Schultz, who are trying to sell weapons to a local killer named Aaron Davis. Parker intervenes and is about to die, but he is rescued by Stark who secretly monitors him and warns him that it is very dangerous to interfere with important offenders. Toomes accidentally kills Brice with one of his weapons, and then Schultz becomes the new Shocker.
