One of his jobs brings him into conflict with the government operative Venom. During this conflict, Venom threw a live grenade into his mouthpiece and it dislocated his jaw. Even after the explosion, he was still able to run and retreat. Later, Crime-Master is able to use contacts to discover Venom's true identity Flash Thompson, and has Jack O'Lantern kidnap Betty Brant (Flash's girlfriend) in exchange for Venom letting Crime-Master get a shipment of Antarctic Vibranium. When Venom leaves to rescue Betty, he is distracted by Spider-Man's appearance, which drives the Venom symbiote into an uncontrollable rage. Eventually Betty is rescued at the last second by Spider-Man, with Venom then trying to recapture Crime-Master. However, Venom is attacked by Jack O'Lantern who proclaims Flash as his first real nemesis, and desiring revenge for the disfiguring grenade explosion, also mockingly calling out Venom's first name. While it hasn't been confirmed, this depiction claims to have killed every other person to go by the Jack O'Lantern name in an effort to "clean up the brand". Jack O'Lantern is a member of the Crime-Master's Savage Six.
