Absalom is a young man with brown skin who carries with him great hatred and fixation with civilization, even willing to kill himself for a world without it. His Stand represents this hate and obsession, taking the form of the very thing he loved and killed his family: a train. When DIO promises to create a new world different from the civilized one, he even is capable of committing suicide to see this dream come true.
Absalom was raised in the deserts of Egypt, but was ashamed of the uncivilized life he had. In his childhood he was attracted to civilization, particularly to trains (even dreaming of driving one), and believing that "the human being can only find happiness in a civilized society". However he became disappointed even with the civilized men and began hating civilization four years ago when his parents died during a family trip in a train accident in Cairo. In that accident, his sister Michal lost her voice because of throat injuries. They both pledged loyalty to DIO, as he promised to create a new world different from both the desert and the civilized ones if the Joestar group is killed. His Stand, Satanic Coupler, represents his fixation and hatred with civilization.
The Joestar group, exhausted from the Nubian Desert's heat, suddenly encounters Absalom, who presents himself as the driver of the "Satanic Coupler" locomotive and offers refuge for them inside it. Revealing the train to be his own Stand, Absalom confines them in it, planning to push the group from hope to despair with enclosure. Absalom tries a suicide attack, planning to destroy his own Stand with everyone inside, but Jotaro Kujo, Jean Pierre Polnareff and Iggy use their wits to escape, foiling his plan. After the defeat of his sister, Absalom confronts them again in his hideout close to an oasis village, his hometown. Because his attack involved a boy from the village, he soon faces the wrath of a furious Jotaro, who discovers his Stand's weakness and hammers it with a barrage of punches thanks to a plan made by a recently rescued Joseph Joestar. His last attempt of resistence is to shrink his Stand and sneak it into Avdol's body, but lost to the also smaller Hierophant Green and Star Platinum and becomes incapacitated. Villagers later mistake the Joestar group as bad people and rescue Absalom, who decides to live with them peacefully.
