Diavolo/History

History
Diavolo was born in an all-female prison sometime in 1967, his birth is a mystery as his mother claimed that she had been pregnant for two years, and all the guards were female. Because she was unable to raise him while in prison, Diavolo's mother sent him to live in her home town of Sardinia with a priest. As he was growing up he was considered dim-witted and timid, but frank, and remarked that he wanted to be a sailor rather than a priest, which his guardian agreed would suit him.

When he turned 19, as the priest was constructing a garage for him, he discovered Diavolo's mother buried alive next to Diavolo's room with her mouth sewn shut. That night a fire broke out, consuming every house in the village. Seven were listed as dead, including Diavolo and the priest. However he survived and created Passione soon after. During the same year his village burnt, Diavolo went on an archaeology expedition to Egypt. Upon finding six arrows, he quickly stole them and left, selling five to Enya for a huge sum of money and keeping the last one for himself (the same arrow attached to Polpo's Black Sabbath).

After the events of Stardust Crusaders Polnareff and Jotaro set out to find the six arrows. Upon noticing the crime and death rates surrounding Diavolo's organisation were twenty times higher than average, Polnareff began investigating Passione and its leader. Diavolo easily defeated Polnareff, damaging his eye, right arm, and legs.

Having found out about his daughter he had given orders to Polpo to protect and bring her to him, but as Polpo was assassinated before he could carry out the order it was inherited by his successor Bruno Buccellati. He decided to kill her himself upon meeting her so that he could erase all major evidence of his identity. It was not until they were there and Diavolo cut Trish's hand off to take her away that Buccellati realised his plan and quickly went after him to retrieve her.

Diavolo is first seen as a shadowy figure in the tower that Buccellati brings Trish to. It is not until later when they meet Polnareff that he truly shows his face.

When Doppio encounters a fortune teller who reads a stain from where doppio fell and mentions his daughter before trying to force him into showing his palms, Diavolo takes control and questions the man about Risotto Nero's whereabouts before ripping off his hand and killing him.

Throughout the fight with Risotto, Diavolo gives advice and encouragement to Doppio, claiming Doppio is his most trusted subordinate; but proves to be the more cowardly of the two as he suggests Doppio escapes with his life while he still has the chance and Doppio refuses. After defeating Risotto and escaping, Diavolo attacks a child, ties his mouth shut with his own shoelace, and drinks his blood to replace the iron in his own blood; donning his football uniform as a disguise to kill Abbacchio.

At the Coliseum, Polnareff was taken by surprise at Diavolo revealing himself and attempted to get the arrow away from him. He was took mortal damage from King Crimson, but used the arrow on his own stand and create Silver Chariot Requiem as a last resort, which caused everyone to pass out for at least six hours and switch bodies.

Upon reawakening, Buccellati's gang follow Silver Chariot Requiem in an attempt to retrieve the arrow before Diavolo, unaware that he was hiding with Trish in Mista's body. After watching the group for a while Diavolo realised how to defeat the Requiem and take the arrow for himself. Just as he was close enough to the arrow to take it Giorno noticed that Mista's gun had been broken by force, causing the group to stop and allow Giorno to check them to see who had Diavolo's soul sharing their body. Diavolo panicked and chopped off Giorno's arm, causing Trish to bring out Spice Girl who he grabbed and used to control Mista's body.

Thanks to having worked out Silver Chariot Requiem's ability, he is able to easily defeat it once he escapes the group in Mista's body, but upon gaining the arrow he immediately drops it thanks to Giorno's dried blood being on his hand and Giorno's ability to turn that blood into termites. He also proves to have underestimated Trish as she softens Mista's bullets with Spice Girl and sends the arrow over to Mista.

He is eventually defeated by Giorno after Giorno's Gold Experience evolves into Gold Experience Requiem and is trapped in an infinite death loop by its effects. He is shown to have died in many different ways, including being stabbed, hit by a car, and autopsied alive. In his last appearance he is shown screaming at a child to leave him alone, clearly terrified of what might happen to him.

2001 (Vento Aureo)
Doppio is first seen in Sardinia, carrying a briefcase. In his introduction the audience is made to believe he is saving a child from being hit by a car, though it is later shown he barely took notice of the child and was actually saving a bug. After possibly subconsciously using King Crimson to avoid being hit by the car, Doppio caught the attention of a fortune teller. While at first sceptical, Doppio became interested in the man's fortune telling until the fortune teller tried to force him into letting him see his hands. After becoming panicked, Diavolo took Doppio's place and killed the man, leaving Doppio to chase his bug again afterwards (terrifying the small boy who was watching).

After getting into a taxi and being conned by the driver, Doppio is met by Risotto Nero. In his rush to get away, Doppio smacks his face against a rock and bleeds profusely, getting blood all over his shoes. When Risotto asks what's in an envelope (containing a photo of Diavolo) he is lead to believe it is only a bit of rubbish as Doppio manages to stick the photograph to the bottom of his foot with his own blood.

During the fight with Risotto, Diavolo tells Doppio that he has been loaned King Crimson's power in an attempt to encourage him to fight back. There is, however, no confirmed way of loaning stands other than Whitesnake's power, which indicates that Doppio could either use the whole of King Crimson from the start or his willpower was only strong enough to use Epitaph and one of King Crimson's arms. Doppio shows great determination to defeat Risotto despite his fear and despite Diavolo warning him to escape. He also proves himself to be very resourceful, using Narancia's Aerosmith and King Crimson in combination to shoot and kill Risotto.

Upon arriving in Rome, Doppio is taken hostage by Secco, who is fighting Buccellati. As neither of them recognise him, Buccellati saves him by placing a zipper on him to punch through him and kill Secco without hurting him. As Buccellati had lost his sight and hearing Doppio easily fooled him into believing he was Trish, allowing him to be lead straight to Polnareff who was obviously wary of him.

When Silver Chariot Requiem swapped the souls of the inhabitants of Rome his soul got switched into Buccellati's body, with Buccellati's soul going to Diavolo's body. After waking up from Silver Chariot Requiem's ability and standing, he was shot by Mista using Trish's body. Though Mista claimed his attack was not enough to kill him, Doppio died nonetheless.
