Daniel J. D'Arby

Daniel J. D'Arby is a minor antagonist in Part III: Stardust Crusaders. He is an American professional gambler, and an enemy of the protagonists.

Personality
Daniel J. D'Arby is a calm and collected man with a very sharp mind, but becomes angry every time someone says his name wrong. He describes himself as living for the cheap thrills of gambling, but this does not seem to deter him from cheating in every way he can to ensure his victory. Cheating was one of D'Arby's greatest skills, something he proudly admits, while his eyes aren't deceived easily in case someone decides to cheat against him. He sees no problem at all in cheating in games, because according to him, the cheated player deserves it for being gullible enough to not notice anything wrong in the first place. Jotaro descrives him as one of the most dangerous stand users, almost beating the entire group without violence.

Synopsis
The Joestar group encounter D'Arby while searching Cairo for Dio's mansion. After asking around in a cafè he is sitting in, D'Arby tells them he knows the location of the mansion, but refuses to share the information for money. Instead, he tries to convince the group to try winning the information from him in games of chance. He first quickly sets up a game to see which one of two pieces of beef a nearby cat would take first. An impatient Polnareff accepts his bet, as well as the condition that Polnareff bets his soul in return, thinking it is all nonsense. D'Arby wins the bet and takes Polnareff's soul with his Stand, Osiris, as well as revealing himself to be one of Dio's men and the owner of the cat involved in the game.

Because of his Stand's nature, the Joestar group had to beat him at his own game to win back their friend's soul. Joseph tries outsmarting D'Arby in a game where they put coins in a glass of liquour until someone loses by causing the glass to spill over, but D'Arby turns out to be the better cheater.

Jotaro then challenges D'Arby at poker, which the gambler comments on is his strongest game. After Jotaro foils his attempt at second dealing by breaking his finger, D'Arby is visibly shaken and declares that he is no longer fighting for Dio, but for his pride as a gambler. He splits Polnareff's and Joseph's souls into five chips each for them to use. They then get a nearby boy to deal the cards for them. Jotaro loses with his pairs of eights and nines to D'Arby's queens and jacks. As it turns out, D'Arby owns the entire cafè and "everyone within a stone's throw of it". He confidently tells himself that no matter who Jotaro picks to deal the cards, he will only get bad hands.

In the second round of the game, Jotaro refuses to look at his cards, saying he will play with the ones he has, which frustrates D'Arby. Jotaro begins raising D'Arby with his remaining "soul chips", as well as Abdul's and Kakyoin's souls, without a single twitch. He also promises to give up Kakyoin's soul instead of his if he forfeits the poker game. This, along with Star Platinum fetching Jotaro a cigarette and a drink without D'Arby's immediate notice, confuses him and causes him to have doubts about whether he truly is in control of the situation anymore. D'Arby's four kings was apparently a guaranteed win, but he begins wondering if Jotaro really has one of the three possible hands that could beat him, or if Star Platinum had switched the cards without him noticing. As D'Arby is about to call, Jotaro raises his mother's soul, demanding D'Arby meet his raise with information on Dio's Stand. This causes D'Arby to panic, knowing that if he were to lose, Dio would have him killed for betraying him. D'Arby tries to force himself to call Jotaro's bet, but he falls apart completely and becomes a hysteric mess, admitting defeat in his heart. Polnareff, Joseph and the hundreds of other souls D'Arby had collected over the years were freed from his collection.

Stand
His Stand, Osiris, is a very big humanoid figure with muscular arms, a face resembling a mask, and mist instead of a lower body, much like how the genie from Arabic folklore is portrayed today. It has the power to extract a person's soul from his body if certain demands are met, upon which is compresses it into a poker chip for D'Arby to put in his collection. D'Arby seems to have a predatory desire for tricking people into his seemingly innocious games, goading the loser's friends and family to try winning back the soul, giving him even larger winnings. He shares this interest in collecting souls with his younger brother, Terence, though Daniel has no interest in keeping the souls conscious in captivity, instead having them in a deep sleep inside his collection. In addition, his collection is meticulously detailed, with every soul's name listed, as well as area and date of capture.
