Steeplejack (Marvel Comics)

Jack Mallard was the first criminal to go by the name Steeplejack. He was a construction worker, and he and his two brothers were employed by contractor Maxwell Plumm. As Plumm unethically cut corners and safety and materials, Mallard's two brothers fell to their deaths when a girder slipped its cable in a sudden wind. He blamed Plumm and vowed vengeance, becoming the first Steeplejack. He attacked Plumm and was about to hurl him to his death from a construction site, when Power Man intervened. Steeplejack fought Cage, and then hurled Plumm from the building, and fled. Cage saved Plumm, who swiftly agreed to hire Cage for protection.

That night, Steeplejack returned to the construction site to sabotage it, and Power Man emerged from hiding to battle Steeplejack. During the fight, Steeplejack fell on one of the girders he had weakened, and it gave with the impact. Mallard plunged several stories towards the street, and the impact caused his fuel tanks to explode, apparently killing him.[1]

Maxwell Plumm took the designs and outfit of the first Steeplejack. He fought Ms. Marvel and lost.[2] He attended the final bash at the "Bar With No Name," and was shot to death by the Scourge of the Underworld.[3]

Roderick Kingsley later sold the Steeplejack gear to an unknown criminal. Steeplejack, Ringer, and Tumbler are shown to be in the services of Roderick Kinglsley. They were later ambushed by the Goblin King's servants Menace and Monster (the "Goblin" form of Carlie Cooper). Steeplejack is killed by Goblin Knight.[4]
