Diavolo

Diavolo (also known as Solido Naso) is the main antagonist of Part 5: Golden Wind.

Diavolo is the boss of the Neapolitan crime syndicate known as Passione. He assumed the identity of the Boss at some point, and became the most powerful man in Italy while selling drugs. He is a man afflicted with dual-personality disorder, and his other half, Aceto Doppio, serves as his second in command. Diavolo lives in total isolation, as no one but his alter ego knows his true identity. Eventually he is tracked down by Giorno Giovanna and Team Bucciarati, and the two of them fight for control over the Stand Arrow, but he inevitably loses to the ultra powerful Gold Experience Requiem. He is killed, and in his final moments, lives out an infinite death loop within his own mind, so that he may never reach the truth of how he dies.

Diavolo shares his time skipping Stand, King Crimson, with Doppio.

Physical Appearance
As himself, Diavolo is a tall muscular man with long pink hair. In his hair are random black splotches. He wears purple pants and has some sort of lace that he wears over his arms and torso.

As Doppio, he appears much younger than his primary personality. He has shorter hair, and wears a pink sweater.

Personality
Diavolo is obsessed with keeping his identity secret. So much so that he does everything in his power to make sure that anyone left alive that knows his identity will die. He is also power hungry, and wants to be in control of fate itself, as later in the part he seeks out the Stand Arrow to evolve his Stand King Crimson and take control of fate.

King Crimson
Diavolo's Stand King Crimson gives him the ability to erase time, meaning that for a certain period of time, the events are "skipped" and only the results of said events remain. Diavolo is able to manipulate fate in this way.

Epitaph
His Sub-Stand, Epitaph, lets him see five seconds into the future.

Age
Diavolo is 33 in Vento Aureo.

Trivia

 * Diavolo means "devil" in Italian.
 * It is ironic that Giorno, son of DIO (meaning God in Italian) fights someone named after the devil.
 * His assumed identity when living in Sardegna (Solido Naso) means "Solid Nose," which is funny I think.
 * He is indirectly referenced in Part 8 with Tooru/ Satoru Akefu, as both Tooru and Diavolo are the leaders of a criminal organization that takes on an assumed identity to hide their true face (Akefu/Doppio.)
