In 1984, editor Len Wein assigned Swamp Thing to British writer Alan Moore. When Karen Berger took over as editor, she gave Moore free rein to revamp the title and the character as he saw fit. Moore reconfigured Swamp Thing’s origin to make him a true monster as opposed to a human transformed into a monster. In his first issue, he swept aside most of the supporting cast Pasko had introduced in his year-and-a-half run as writer, and brought the Sunderland Corporation to the forefront, as they hunted Swamp Thing and “killed” him in a hail of bullets. The subsequent investigation revealed that Swamp Thing was not Alec Holland’s consciousness transformed into a plant but actually a form of plant life that had absorbed Holland’s consciousness after exposure to his work, with Swamp Thing’s appearance being the plants’ attempt to duplicate Holland’s human form.
