Background
J. Geil is the man responsible for the rape and murder of Sherry Polnareff, earning him her brother's desire for revenge. He also tried to kill Sherry's friend but failed. No one but Polnareff believed the girl's testimony on J. Geil having two right hands.[9] It is later implied that he raped numerous girls before Sherry, as he says that he had many girls who "loved and admired" him, Sherry being just one of them.[10]
Entering DIO's service like his mother Enya, he is one of the seven Stand Users sent in Asia to stop the Joestars. J. Geil is first explicitly mentioned by Rubber Soul, who reveals a part of his ability to Jotaro Kujo.[11]

Hanged Man sent to taunt Polnareff
In Calcutta, J. Geil makes his Stand appear in front of Polnareff and forcing him to separate from the rest of the group, making him an easy target for him and his partner Hol Horse.[12] He later joins up with Hol Horse to confront Polnareff, knowing that their bait has succeeded.[13] After a short confrontation between Emperor and Silver Chariot, Muhammad Avdol joins the fight but is quickly disposed of by a combination of the antagonists' Stands.[14]
Polnareff is blinded by anger and is almost killed in the same way, but Noriaki Kakyoin manages to save him in time. The two escape with a jeep,[15] but Hanged Man follows them and destroys the vehicle. At this point, Polnareff deduces J. Geil's Stand's true nature: it is made of light and can move between reflections at high speed and attack from there. Having guessed its location and trajectory, Silver Chariot manages to stab it, revealing J. Geil's position.[16]
J. Geil defeated by Polnareff
When Kakyoin and Polnareff finally confront J. Geil, Polnareff gloats by explaining Hanged Man's ability. However, Polnareff and Kakyoin are once again tricked: J. Geil slashed a man in the chest as a decoy and left him there to place the duo in a trap. He gathers a crowd of people and makes its Stand enter their eyes. The trick is foiled by Kakyoin, who focuses the people's attention on a coin while Polnareff then kicks dirt in everyone's eyes and then cuts the fleeing Hanged Man with Silver Chariot. Silver Chariot then finishes J. Geil with a flurry. Flung into the air from the final blow, J. Geil comes down hung upside down on a gate, becoming a visual metaphor for the Tarot card his Stand represented.[17]
