OVA
Description
J. Geil is a minor antagonist in the third part of the series, appearing in the "Emperor and Hanged Man" story arc. An assassin and the son of DIO's advisor Enya the Hag, he was dispatched alongside Hol Horse to eliminate the Joestar Group. He is the murderer of Sherry Polnareff and the target of Jean Pierre Polnareff's quest for vengeance. J. Geil is a Stand User whose ability is named Hanged Man.

He is a muscular man of average to above-average height, distinguished by the presence of two right hands. His appearance is notably hideous, featuring a bald head with an abnormally high crown and a gaunt face with blank, squinted eyes, a small nose, and a nearly toothless mouth. Earlier depictions show him with long, gaunt hair, though it remains unclear whether this was his natural hair or a wig. He typically wears a plain shirt, trousers, a leather jacket, and arm warmers. Upon his initial introduction, he is also shown with a dark purple turban-like cap and a face veil, which do not appear later. In his youth, he wore attire resembling either a dress suit or a private school uniform.

J. Geil is a thoroughly amoral and depraved psychopath. He operates primarily from concealment, relying on a partner—a trait that made him compatible with Hol Horse. While Hol Horse shattered glass to enable his Stand’s function, J. Geil remained hidden in shadows, occasionally executing combination attacks. His personality is profoundly twisted and sexually depraved, ranking him among the most reprehensible of DIO's followers. He habitually raped and murdered young girls, expressing no remorse. He openly boasted of these crimes and derided Polnareff for failing to avenge his sister. When confronted directly, he exhibited cowardice, attempting to flee and begging for mercy.

His Stand, Hanged Man, is composed of light and can travel between reflective surfaces. By attacking a person’s reflection, it inflicts injury on the actual individual. This power depends on reflective surfaces such as glass or eyes to operate effectively.

J. Geil committed the rape and murder of Sherry Polnareff. He also attempted to kill her friend, succeeding in decapitating her in the OVA adaptation though failing in the manga. His remark about being “surrounded by young beauties like your sister” strongly implies a long history of such crimes. These actions motivated Polnareff to join the Joestar Group in pursuit of revenge.

During Stardust Crusaders, J. Geil and Hol Horse ambushed Polnareff, isolating him from his allies. After an initial struggle, Polnareff and Kakyoin deduced Hanged Man’s abilities. They used a coin to concentrate the Stand’s movement and struck it as it tried to escape. This revealed J. Geil’s location, and he attempted to flee. Polnareff cornered him and executed him with multiple stabs from Silver Chariot. J. Geil’s body was left hanging upside down on a gate, evoking the Tarot card after which his Stand is named.

In the OVA adaptation, J. Geil pleads for mercy as he dies, but Polnareff refuses, citing the absence of mercy shown to his sister.

J. Geil appears in the video game "Heritage for the Future," where Hanged Man is incorporated into Hol Horse’s moveset, capable of immobilizing opponents or assisting in damage-dealing through specific game mechanics.

He is noted for having two right hands, though an error in the first Italian edition of the manga depicted this as two left hands due to mirror-printing. His localized name, Centerfold, refers to a fold-out page in pornographic magazines and shares its name with a song by The J. Geils Band.

Enya the Hag, J. Geil’s mother, mourned his death. This reflects her delusion regarding her son’s nature rather than implying any redeeming qualities in J. Geil.
