J. Geil is the individual accountable for the murder of Polnareff's sister, a deed that ignited Polnareff's thirst for vengeance.
Most of J. Geil's time is spent evading detection, favoring the presence of a partner to depend on. This characteristic made him an ideal match for Hol Horse, who shares the belief in the efficacy of working in pairs. While J. Geil would lurk in the shadows, Hol Horse would shatter the glass required for his Stand to operate, occasionally executing coordinated assaults. For instance, Hol Horse might break the glass while J. Geil attacked simultaneously, and Hol Horse fired a bullet from his Stand, Emperor, trapping the enemy within a deadly loop.
Akin to his mother, J. Geil possessed a deformity granting him two right hands.
