Amazing Spider-Man #131, page 6 (1974) Appearing in "My Uncle... My Enemy?" Rushing to the Westchester County mansion of Doctor Octopus, Spider-Man arrives just in time to see that his arch-nemesis is about to get married to his Aunt May. Before Spider-Man can react, Hammerhead and his goons bust in on the marriage with guns blazing. Octopus fights off some of Hammerhead's men, and manages to make an escape with Aunt May through a secondary exit. Spider-Man intercepts them and tries to stop Octopus from getting away, but he is knocked out. Octopus then makes his escape with May in a helicopter. Witnessing this, Hammerhead and his men decide to follow after Octopus in the helicopter that they arrived in themselves. Spider-Man, reviving from his blow from Doctor Octopus, secretly hitches a ride aboard Hammerhead's helicopter.
