~ Vinegar Doppio

Vinegar Doppio is a side character and the secondary antagonist featured in JoJo's Bizarre Adventure: Golden Wind.

Doppio is Diavolo's younger, more innocent and eccentric underboss. As a member of Passione, he thinks of himself as the most loyal subordinate to Diavolo, but the two are actually separate souls inhabiting the same body.

During the course of Vento Aureo, he helps Diavolo to act and move around undetected. Doppio is allowed to partly wield King Crimson in battle.

He is voiced by Sōma Saitō in the Anime Adaptation, and was voiced by Akira Ishida in JoJo's Bizarre Adventure: All-Star Battle and JoJo's Bizarre Adventure: Eyes of Heaven.


Doppio is first seen in Sardinia, carrying a briefcase. In his introduction he appears to be saving a little boy from being hit by a truck as the boy is seen playing with 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 skeptical, Doppio became interested in the man's fortune telling when he began telling him that he had a daughter, even though he looked far too young. The fortune teller himself was left astonished that Doppio was a father, and pried to see his palms, leaving him uneasy. Doppio begins to panic as the fortune teller began to harass him not of a desire for money, but to figure out the mystery behind the strange boy. Doppio suddenly snaps and physically changes, grabbing the fortune-teller by the throat, telling him that he's a dead man. The fortune-teller realizes that his attacker has two personalities, light and dark. It is then that Diavolo executes the Fortune Teller with King Crimson. The boy from before witnesses this, but it's Doppio who emerges from the shadows who pushes him out of the way, and tells the bug that was next to him to be careful as the boy runs away screaming and crying in fright.

After getting into a taxi and being conned by the driver, Doppio arrives at Donatella's house seemingly with no sign of pursuers. but is "called" by Diavolo through Doppio's imaginary phone and told that they are being watched. Doppio turns around and sees Risotto Nero, having arrived to attack Team Bucciarati when they inevitably arrive at the house as well. Instructed by his Boss to get Risotto within two meters so as to allow King Crimson to kill the traitor, Doppio waits for Risotto to appear behind him and turns around to attack. However, Risotto quickly outmaneuvers him and Doppio smacks his face against a rock. Left bleeding profusely enough to get blood all over his shoes, Doppio begins to panic. When Risotto questions what's in an envelope (containing the photo of Donatella) underneath Doppio that the young man appeared to have deliberately hid, he is led 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.

Though Doppio has convinced Risotto that his fear and cowardice were genuine, Risotto notices that Doppio reacted to the sound of Aerosmith patrolling the area, and figures out that he's a Stand User. Doppio once again attacks Risotto, but it is then that razor blades suddenly appear in his mouth. Attempting once more to attack Risotto by running at him unintentionally reveals to the assassin that whatever Stand Doppio has must be a close-ranged Power-type, and keeps himself from getting within 2–3 meters. Needles then begin spewing out of Doppio's mouth, leaving him even more confused to Risotto's Stand as the assassin suddenly disappears. Diavolo calls Doppio through Doppio's imaginary phone and grants him Epitaph to predict Risotto's movements, as well as King Crimson's arms. The first thing Doppio forecasts using Epitaph is Risotto turning invisible and a pair of scissors inexplicably forming in his neck, ready to cut his throat. He wonders how the scissors could move on their own, and before they could snip his throat, he forcefully tears them out. Risotto once again disappears, and Doppio sees a foot getting severed. He tells Diavolo what happens, and is ordered to run away. However, he figures out Risotto's Stand, Metallica's ability, and throws the scissors in a direction. The scissors sever Risotto's foot while a nearby frog explodes into razors. This proves to Doppio that Metallica's ability is that of magnetism of the iron in blood. Just then, multiple knives created from the iron in sand are sent at Doppio, and while he deflects most of them, few are able to strike him. Diavolo reprimands him and tells him that he is "on his way" to finish Risotto off himself. Risotto, now aware of Doppio's pre-cognitive abilities, reattaches his foot with metal staples while noting Doppio's two different personalities and turns invisible once more.

Doppio peers into Epitaph's forecast and sees a large chunk with blood gushing missing from his own head, causing him to panic. While his body begins to change as Diavolo slowly emerges, Doppio uses the knives to pinpoint Risotto's location like a compass. However, upon throwing them, Risotto reveals that he expected it, and actually detached his severed foot for the knife to locate. Razors start forming in Doppio's head, and Risotto prepares to finish off Doppio, slowly coming to the realization of the identity of Doppio's second personality. The instant he orders the razors to explode out of Doppio's head, Risotto is shot by a volley of bullets. Diavolo takes over and reveals that the knives thrown were in the direction of Bucciarati's group, causing Aerosmith to attack whomever was in the direction of the thrower. As Doppio has lost a lot of blood and is heavy on breath, Risotto, the larger blip on Narancia's radar, was targeted. More bullets rip through Risotto, sending his still-invisible skin flying and landing on Diavolo's body, revealing the cause of the missing chunk in Doppio's head. Diavolo is left standing over Risotto in victory, and offers him a quick and honorable death in exchange for him restoring his iron levels to normal. However, as a last resort, Risotto uses Metallica, caught on Aerosmith when his skin was sent flying, to guide Aerosmith and shoot Diavolo. Diavolo erases half a second to avoid the bullets, and Risotto ends up getting shot himself, bringing an end to the assassin.

Doppio is used to disguise Diavolo, in combination with the stolen clothes of a child Diavolo kidnapped, to allow him to get close to Leone Abbacchio and kill him before his Moody Blues could reveal Diavolo's face. Later, Diavolo "calls" Doppio and reluctantly orders him to send Cioccolata and Secco, the last remaining members of his elite guard after Bucciarati's team.

Upon arriving in Rome, Doppio is taken hostage by Secco, whom is fighting Bucciarati. As neither of them recognise him, Bucciarati saves him by placing a zipper on him to punch through him and kill Secco without hurting him. As Bucciarati 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 Chariot Requiem swapped the souls of the inhabitants of Rome, his soul got switched into Bucciarati's body while Bucciarati's soul went to Diavolo's body. Team Bucciarati keeps a close eye on Bucciarati's body. The moment Doppio began to awake, he was shot down by Mista in Trish's body. Though Mista claimed that the shots would not be fatal, Doppio eventually bleeds out on the pavement. Before his death, he claims that he feels lonely and was waiting for a call from Diavolo, whom left Bucciarati's body knowing it was dangerous to stay, sacrificing Doppio to keep himself alive. Despite this, Doppio viewed his Boss' decision as a smart one that would allow him to defeat the traitors.


Doppio appears as a slim yet fit young man/boy (described as having the physique of a person in their late teens). He has freckles, contributing to his boyish looks, and pink irises that disappear when he is not in control of the body. His hair is tied into a neck-length ponytail, tied back with a hair clip in the manga but the anime changes it into a weave-like braid. The front hair is left loose and sweeps over to one side lock, the position and length of which is portrayed inconsistently.

His clothing consists of a light-colored sweater with gash-like openings on it that leave the midriff exposed and loose purple jeans with studs openings on the thighs and ankle sides. Doppio also wears a black mesh shirt underneath the sweater.


Doppio is a much more regular person in contrast to Diavolo: friendly, honest, and a bit cowardly. Doppio regularly hallucinates random objects as "phones" with which he talks with his alter-ego, not knowing that they share the same body.

Doppio mostly behaves like a good-natured teenager, and is by default a friendly and polite individual. Doppio frequently seems good with children as he once successfully borrowed a toy phone from a child while taking a train, and even risked his life to save another one. Whenever attacked, Doppio automatically reverts to a state of true fear and submission, often choosing the safest option such as comply with his aggressor's demands. He believes himself to be unlucky, which provides an ironic contrast to Diavolo's good fortune.

Fiercely loyal to his boss to a point of attempting to fulfill the mission first and foremost, Doppio is smart and quite resourceful, even if Diavolo has to counsel him from time to time. Despite this, though, bits of Diavolo are in Doppio: during the battle with Risotto Nero, Doppio refused to leave the battle or have his boss step in, remaining and doing all he could to find weakness in Risotto's Stand, Metallica. He shares his alter ego's collected nature when in battle, and while his first actions are usually panicking and screaming, he soon and very quickly calms down, carefully using his tools to identify the enemy and his powers. He is able to think several steps ahead, having baited Narancia to attack Risotto Nero by taking advantage of his own weak position and predicting Risotto's moves.

As Diavolo is very gentle and patient with Doppio, he is usually completely unquestioning, agreeing to whatever his "boss" says. As he dies, Doppio's last thoughts are of his boss, remaining faithful until the end and smiling, saying that if Diavolo is going with them he'll surely win and asks Diavolo to call him, remarking that he feels lonely.

However, Doppio is also quick to anger, and swears heavily during these fits, though unlike Diavolo he is less controlled and focused with it. Snappy, Doppio flat-out disobeyed and argued with his direct superior during the battle with Risotto, berated Bucciarati for nearly falling into the street, and even rebuked Diavolo himself once more for "calling" him in Bucciarati's presence. He also has low tolerance and almost zero patience for "idiots" and people who withhold "phones" from him.

Doppio has been shown questioning fortune telling, as he stated that some of the guesses the fortune teller made were simply that due to his appearance ("you're a tourist," because of his bag, "you have a secret" because everyone does, etc.).

Even with the bridge of personality to personality, however, he is seemingly unaware of their co-inhabitance and appears to consider himself Diavolo's underboss and, furthermore, Diavolo as an entirely separate person. The source of this ignorance is dissociative. Diavolo was shown moving Doppio out of the alley shortly after killing the fortune teller so he didn't see the corpse, but it's also possible that Diavolo withholds memories from Doppio. Doppio seems to be largely unaware of what the objects he calls "phones" really are which he uses to converse with Diavolo, being capable of hearing the Boss' voice come from whatever he's grabbed, be it ice cream or a frog. He seems to have a poor memory to top it off, but whether it's due to his Mental Illnesses or Diavolo's ability to withhold information from Doppio is unknown; Before encountering Risotto, Diavolo warned his alter ego that the assassin was in the area and gave him strict instructions on how to deal with him and how to complete the mission. However, upon "hanging up", it didn't take more than a brief moment for Doppio to immediately forget his mission, what he was just ordered, the fact that Risotto was in the area, and above all, how he managed to talk to the boss despite his phone being broken.

Mental State


Doppio shows signs of DID (Dissociative Identity Disorder) and Schizophrenia, such as Memory Loss/Amnesia, Headaches, Hallucinations (Mostly phones) and Unawareness that he and Diavolo share the same body. While Doppio is a polite man, he can be quick to anger and act bipolar once stressed.

It is theorised that Doppio is the original personality or alternatively the dominate one, as the Boy seen in the flashback had fashioned his hair into a braid like Doppio, had freckles just like Doppio does and Doppio fits the "honest but dim" description better. However, whether this is true or not is currently unknown. In the anime, Doppio's voice actor, Soma Saito, also voiced the boy in the flashback, implying it even more. When Silver Chariot Requiem swapped everyone's souls, Diavolo wasn't transferred to a separate body, but instead his soul latched onto Mista's body which had already another soul in it, implying that Diavolo needs a Host to be able to live on while Doppio was transferred to Buccellati's body where he was able to live on alone until he was killed by Mista. When Polnareff explained DID, he used Billy Milligan as example.
