Golden Wind

Boss of an Italian crime organization "Passion", secretly controlling all underground businesses in Italy. The scope of Passion includes drug dealing, illegal trades, and politics.

Born in a jail after his mother's two-year pregnancy, Diavolo naturally grew pink hair, he doesn't cry and has eyes wide open after his birth. The strange things happened to him and his weird appearance makes him more like an avatar of the devil rather than a normal human.

Diavolo is evil incarnate, he lived a happy childhood after been adopted by a godfather and behaved like a cowardly child for a long time. However, one day the godfather accidentally finds out Diavolo's mother buried under floors in his house. Diavolo then kills the godfather and burns the entire village, then he left his home. Nothing in his life experiences forges his evil, he just born to be that way.

After getting a job digging an Egypt remnant, Diavolo accidentally finds six Stand Arrows. Those arrows can awake powerful beings generated from people's life energy, those beings are "Stands". He sold five arrows to Dio Brando and got paid a lot of money. Using that money, Diavolo founds the "Passion" and secretly runs the organization.

Another secret of Diavolo is he has dissociative identity disorder. There is a secondary personality named "Doppio" hides in his body. Doppio is a cowardly person who seems harmless. Diavolo usually lets Doppio controls his body and Doppio believes himself is Diavolo's trustful follower. Doppio always uses a phone to speak with Diavolo, without noticing Diavolo is actually another personality inside his head. When he cannot find a phone, he will grab a random object near him and imagine it as a phone. Doppio seems short and skinny, but when Diavolo takes control, his body somehow turns more masculine with muscles pops out. Diavolo appears as Doppio to give commands and claims himself as Diavolo's messenger, since no one in the organization ever saw Diavolo, everyone just believes they are different person.

Diavolo stabbed himself with the remaining arrow, and gains a Stand named "King Crimson". He has the power to "delete" a few seconds of time.

After accidentally discovered he has a daughter Trish Una, he commands a team of Stand users to bring Trish to his base, while his true purpose is to kill Trish by himself to prevent anyone track his real identity.

However, a member of the team Bruno Bucciarati finds out Diavolo's true purpose and decides to betray him to protect innocent Trish. Then, the whole team turns against Diavolo except one decides to quit and left.

King Crimson

Diavolo finds out Stand Arrows can awake people's Stands, which are entities generated from people's life energy representing people's mind and spirit, each stand has a unique superpower, and people who have abilities to summon stands were "Stand Users". Diavolo's stand is named King Crimson, it appears like a strong, muscular man with red, leather-like skin and white armors covering shoulders and belly. It has strange octopus eyes, and a small, pink face on its forehead.

As a Stand User, Diavolo can summon King Crimson whenever he wants or hides it in his body. King Crimson is a close-range Stand, so it stays in a range of 2 meters away from Diavolo's body after being summoned. The power of King Crimson is to "delete" a few seconds of time.

A secondary power of King Crimson is Epitaph, which is from the small face on the forehead. This power is to predict several seconds of the future to Diavolo.

Powers

• Delete time: King Crimson can somehow "delete" time for a few seconds. When using this power, people will do what they intend to do during this time, and forget these few seconds ever happened. This is because time is deleted during those few seconds, so normal people won't experience this time, they also cannot change their decided moves during this time. Only Diavolo himself can feel the deleted time and able to move freely during these seconds. From other people's view, it seems Diavolo just suddenly disappears.
• Intangible: When deleting time, Diavolo becomes invisible and intangible in the few seconds he deleted. This power makes him able to phase through anything to dodge incoming attacks effectively. However, this intangibility also makes him unable to interact with other objects when deleting time. Diavolo cannot touch or attack anything when deleting time.
• Predict Future: The little face on King Crimson's head can use a power named "Epitaph". This power will show visions of several seconds of the future to Diavolo's eyesight. This power is extremely practical when co-works with the power of deleting time. Diavolo can sense possible attacks by Epitaph, and delete time to avoid those attacks by turning intangible.
• Strength: King Crimson's strength is much superior to normal human and most Stands. Its strength is rated A in Stand's standard, thus it can destroy large rocks, walls, and flesh bodies using bare hands. The signature move of Diavolo is to penetrate enemy's body with King Crimson's fist. Diavolo usually deletes time and sneak behind his enemy, then suddenly attacks after the time flows normally.

Characterism

Diavolo desires to be a secret underground emperor. He doesn't let anyone know his true identity and never shows up himself. To avoid exposing his identity, he even decides to kill his only daughter in order to prevent anyone from investigating his identity through his bloodline.

His Stand power is almost invincible in solo fights since he can predict and dodge all attacks by deleting time, but he tends to avoid fights when facing multiple opponents since he can't bear the risk of left any enemy sneak away and reveal his identity.
