Vinegar Doppia | 'Dealing' with you

APPEARENCE: Doppia appears as a fairly slim yet fit young woman, described as appearing too young to have children. She has freckles, contributing to her girlish looks, and light-colored irises that disappear when she is not in control of the body. Her hair is tied into a neck-length ponytail by 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.

Her clothing consists of a light-colored sweater with gash-like openings on it that leave the midriff exposed and a loose pair of jeans with studs covering the thigh as well as studded loafers

PERSONALITY: Doppia is a much more regular person in contrast to Diavola: friendly, honest, and a bit cowardly. Doppia regularly hallucinates random objects as "phones" with which she talks with her alter-ego, not knowing that they share the same body. Doppia mostly behaves like a good-natured teenager, being friendly and polite. After borrowing a toy phone from a child while taking a plane, she apologizes for taking too long. She cares for insects, risking her life by jumping in front of a truck to save one when a kid was about to catch it. Whenever attacked, Doppia automatically reverts to a state of true fear and submission, often choosing the safest option such as comply with her aggressor's demands. She believes himself to be unlucky, which provides an ironic contrast to Diavola's good fortune.

Fiercely loyal to her boss to a point of attempting to fulfill the mission first and foremost, Doppia is somewhat resourceful although Diavola has to help and counsel her from time to time. Despite this, Doppia has a sense of pride. During her battle against Risotto Nero, Doppia refuses to leave the battle or have her boss step in, remaining and doing all she could to find a weakness in Risotto's Stand, Metallica. She shares her alter ego's collected nature when in battle, and while her first actions are usually panicking and screaming, she soon and very quickly calms down, carefully using her tools to identify the enemy and their powers.

As Diavola is very gentle and patient with Doppia, she is usually completely unquestioning, agreeing to whatever her boss says. As she dies, Doppio's last thoughts are of her boss, remaining faithful until the end and smiling. She believes that Diavola will surely win and asks Diavola to call her in her last moments, remarking that she feels lonely.

Doppia is subjected to angry mood swings, and swears heavily during these fits, though unlike Diavola she is less controlled and focused with it. Snappy, Doppia flat-out disobeys and argues with the Boss during the battle with Risotto, berates Bucciarati for nearly falling into the street, and even rebukes Diavola himself once more for "calling" her in Bucciarati's presence. She also has a low tolerance and almost zero patience for "idiots" and people who withhold "phones" from her.

Doppia doesn't believe in fortune telling, stating that some of the claims that a fortune teller made were simply guesses due to her appearance, such as thinking that she's a tourist because she has a bag.

She is entirely unaware that she shares a body with Diavolo, considering herself Diavola's underboss and, furthermore, an entirely separate person. Doppia strongly believes that any object can become a phone when she needs to converse with Diavola, including an ice cream cone, a burned cigarette, or even a frog. She seems to have a poor memory as well; before encountering Risotto, Diavola warns her alter ego that the assassin is in the area and gives her 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 Doppia to immediately forget her mission, what she was just ordered, the fact that Risotto was in the area, and above all, how she managed to talk to the boss despite his phone being broken

Abilities: Due to sharing the same body with Diavola, Doppia is at least partially capable of using King Crimson, notably its Epitaph, a sub-ability of Queen Crimson, as well as Queen Crimson's arms. However, Diavola informs Doppia that she’s only lending her these abilities. As such, it allows Doppia to see ten seconds into the future and perform powerful strikes the same way Diavola does. According to Diavola, however, Doppia cannot use Queen Crimson's signature ability unless Diavolo himself takes over the body.

Doppia and Diavola are two souls that inhabit the same body. As a result, they can switch their personalities as well as their physical appearance. Compared to Diavola, Doppia appears a lot younger and is described by a fortuneteller as looking too young to have children. Diavola appears to be a lot taller, as well as more busty. When she takes over, Doppia's freckles disappear, her voice deepens, and her hair is seemingly a different length. According to Diavola, it takes a couple of seconds for her to completely take over Doppio's body.

Diavola seems to be able to manipulate Doppia's memories, as Diavola remembers everything and can see everything that happens to Doppia but not vice versa, although it's unknown how much of this is based on Doppia's possible poor memory.

Doppia can communicate with Diavola through any kind of object while not in control, making the underboss believe she is another person altogether. Doppia can always hear her alter ego's voice through the object. Whenever Diavola wants to talk to her, Doppia subconsciously making a ringing noise and grabs a random object in her vicinity to act as a phone. Doppia also always carries a broken or dismantled phone headset.
