Perona

Perona (ペローナ) is a girl dressed in a 'gothic lolita' fashion that is able to produce ghosts from her body. She is the Zombie Animal and Zombie Ambush Commander of Thriller Bark. She is one of the major antagonists of the Thriller Bark arc.

Appearance
Perona's looks are inspired by the 'Gothic Lolita' style, with black, white and bright red clothing. Her hair is light pink colored and very long. Perona's usual hair style has it tied in two high pigtails with somewhat flower-shaped black and white hairpins, and she always wears a red crown with a cross on top. Her stockings cover her entire legs and wears a mini-skirt to match. She is often seen carrying around a red umbrella shaped somewhat like a cute version of a mini devil before her battle with Usopp. She is drawn in a rather different style from the usual, with big round eyes. She's always wearing red lipstick and a thick layer of eyeliner.

In Hogback's flashback, she is seen as a child. While her crown is visible, the rest of her outfit is hard to see, however she seemed to be wearing a dress that gave her a childish appearance.

Personality
Perona is confident and firm with herself. She dislikes people telling her what to do and dislikes anyone disobeying her will. She was even willing to put Absalom in his place and remind him of where her authority lies on Thriller Bark. In the original japanese manga, she normally speaks using a very masculine language, despite her looks.

She apparently likes 'cute' creatures and will only allow someone to work for her if they are cute. Her dream is to create a country where all the 'cute' people are turned into zombie animals that obey only her. She dislikes Kumacy because, although he is cute in appearance, his voice is not, and thus she prefers him to just be quiet. Her desire for cute things gives her a slight childish outlook on some issues. She is very playful, threatening to burst Usopp's heart when she was in her ghost form. Usopp nearly died of the fear itself, and got enraged when Perona simply laughed it off, saying she could do no such thing.

She seems to be terrified of cockroaches, even to the point of screaming in fear and believing that plastic cockroaches are real ones. Also, she seems somewhat naive, not doubting for a second that Usopp can lift ten tons.

Like many of the One Piece cast, she has her own unique laugh that use the word Horo. (i.e Horo-horo-horo-horo-horo!)

Enemies
In the short amount of time she appears in, she makes enemies with one particular member of the Straw Hats: Usopp. This is mainly for him defeating her in battle, handing her the first defeat she had ever suffered. She completely ignored Nami when she met her later, stating "the long-nose" is her foe, not her.

Devil Fruit
With the use of her Devil Fruit, Perona is able to conjure up ghosts and form a "ghost network" using them. She either conjures up one ghost or splits herself into many ghosts, able to reform whenever she pleases. Once formed, the ghosts are able to split up into even more ghosts. When a ghost passes through a person they are drained of all their will to live leaving them slumped on the ground regretting even being born, rendering them an easy target.

Despite her powers she so far seems to lack any alternative approaches to fight with. When her Horo Horo no Mi powers failed to stop Usopp she herself became negative and continued to persist with using her powers against him even though she had already failed. However, an additional ability that Perona has is the ability to create exploding ghosts that can make holes in stone walls, and a giant ghost that is even more powerful (although its destructive capabilities are not shown). As well, she can create an astral projection of herself, which can't be hurt through any means. She can pass through solid objects in this form, although she can't damage them, and she can change in size. However, while she is doing this, her true body remains unconscious and vulnerable. To negate this, she usually hides before resorting to astral projection.

Thriller Bark Arc
Perona has been with Moria and Absalom for over 10 years. When she is seen meeting Hogback, she was still a young girl. She was holding a bear that seems to have been later used as source of inspiration to make a real life replica, Kumacy. It is unknown if Perona is a survivor of Moria's original crew or a new recruit.

Five years ago, she was sleeping while Brook was causing trouble in Thriller Bark. This explains why she never heard of him. When Kumacy tried to wake her up, she simply told him to shut up and went back to sleep.

Perona uses her negative ghosts to scout the ship and the nearby area, presumably looking for people whose shadows can be used for Moria and Hogback's experiments. She recently got into a fight with Usopp, who was immune to her negativity ghost attack. During this fight, her faithful servant Kumacy was effectively killed, since his shadow was removed from him, reverting him to a lifeless corpse. Usopp pursued her and figured out the way her ability (creating a copy of herself using astral projection) worked and succeeded in defeating her using a super-sticky glue to keep her in place, plastic cockroaches (which she took to be real ones), the Usopp Golden Pound, an attack involving his new 10-Ton Hammer (actually a balloon). Oddly enough, despite being the leader of a zombie army, Perona is scared fairly easily. She fears Usopp simply because her negative ghosts don't work on him, and she is so terrified that she faints when encountered with cockroaches and Usopp's "10-Ton Hammer" balloon.

She is later seen, still passed out, surrounded by her zombies while Oz rampages through Thriller Bark. When she wakes up later, after been taken by the zombies to another (probably safer) place, she's still confused and scared, thinking that Usopp is still there, and keeps screaming about the hammer and the cockroaches as if she was still talking to him. She's then informed by the zombies that Usopp's gone already and that the damage done to the building wasn't made by the Strawhat Pirates like she first thought, but by Oz. Just after they finish talking, Oz's arm broke the wall close to her, hitting a few zombies. She got scared and hid behind a rock that should have been a part of either the wall or the ceiling before. When she hears Oz saying he's looking for a "woman" (referring to Nami), she freaks out and decides to run away from Thriller Bark using the pirates' ship, as she thinks that that's way too much for her and that Thriller Bark is already done for.

Current Events(Spoilers)
As she comes upon the Sunny, she is confronted by Bartholemew Kuma. When she refuses to tell Kuma where Moria is, Kuma makes Perona disappear. It is unknown exactly where she is now, however, Kuma asked where she would like to go, and she answered 'somewhere near an old castle engulfed in malice' and disappeared. It is comfirmed that he sent her flying with his Paw Paw fruit ability, though whether it's actually possible for him to target a specific location is unknown. When Hogback and Absalom escaped Thriller Bark later, they left without Perona, stating they could not find her anywhere.
