A buyer at an arms deal who got arrested, held a grudge for years, and came back with a list of names.
MacDonald Gargan is a professional criminal and one of Adrian Toomes’s potential buyers. After an encounter with Spider-Man on the Staten Island ferry in 2017 he is arrested by the FBI and swears revenge, and while recovering he approaches Toomes in prison on the strength of a rumour, wanting to know Spider-Man’s identity.
That prison scene, after the credits of Homecoming, sat unresolved for nine years. It is one of the longest running unpaid setups in this catalogue.
