Description
Perona, who styles herself the Ghost Princess, is a young woman with pink hair usually worn in twin tails, a crown-like hair ornament, and a Gothic Lolita wardrobe. She is about eighteen years old when she is introduced. She serves as a former commander of the wild zombie and surprise zombie divisions aboard the island ship Thriller Bark, working under Gecko Moria, one of the Seven Warlords of the Sea, and she is one of the crew's four high-ranking members known as the Mysterious Four. She also oversees the Perona Wonder Garden, a section of Thriller Bark where an army of animal zombies lives and serves as her protectors.

Perona gained her powers by eating the Horo Horo no Mi, a Paramecia-type Devil Fruit also known as the Hollow-Hollow Fruit or Ghost-Ghost Fruit. The fruit allows her to create and control ghostly apparitions. Her most famous technique, the Negative Hollow, sends a ghost through a target's body and floods them with overwhelming pessimism and despair, temporarily draining their will to fight. She can also produce explosive ghosts for direct attacks, release her spirit from her physical body to observe and roam freely, and levitate or fly while keeping her body intact. Her recurring laugh, horohorohoro, plays on the word horo, which means ghost and mirrors the name of her Devil Fruit. Because her combat style relies on psychological manipulation rather than physical strength, it has clear limits. Individuals with unusually strong wills or deeply pessimistic outlooks can resist the Negative Hollows, as shown during the Thriller Bark conflict when Usopp remained unaffected and Perona herself became overwhelmed after firing too many hollows at him at once. She is also vulnerable to attacks that target the soul or spirit, such as those used by Brook.

In terms of personality, Perona is childlike, spoiled, and self-absorbed. She acts on her own whims, dislikes being told what to do, and has little patience for anyone who disobeys her. She is sharp-tongued and bossy, often shouting at her subordinates, yet beneath that bratty exterior she is lonely and emotionally vulnerable, and she can cry when she is alone. She has a strong fondness for anything cute and a strong aversion to anything she considers not cute, such as insects, and she is particularly afraid of cockroaches. She is also quite gullible and can be easily fooled. Despite her selfish tendencies, she is capable of genuine kindness, gratitude, and loyalty toward the people she respects, and she shows a softer side to those close to her, such as her teddy bear-like zombie companion Kumacy, whom she scolds but clearly cares for. Her central motivation is the dream of ruling her own kingdom populated by cute zombie animals, a goal that reflects her playful, self-indulgent view of the world.

In the story, Perona acts as one of the main antagonists of the Thriller Bark arc. She raids the Straw Hats' ship, the Thousand Sunny, with a group of zombie followers and later confronts several crew members, including Zoro, Sanji, Usopp, Franky, and Nami. Her Negative Hollows easily drain the fighting spirit of most of them, and she proves to be a dangerous opponent through psychological tactics rather than direct combat. She is eventually captured by the Straw Hats, and Moria's defeat leads to the collapse of Thriller Bark. A running gag in her early appearances is that she slept through the arrival of Brook years earlier, so she has no memory of him or the events surrounding his appearance.

Perona's later development takes place after she flees to the dark island of Kuraigana following Thriller Bark's destruction. There she encounters Roronoa Zoro, who is severely injured after the Straw Hats' battle with Bartholomew Kuma. Despite initial hostility between them, she tends to his wounds and eventually forms a bond with him. During the Straw Hats' two-year separation, Perona lives on Kuraigana Island alongside Zoro and the swordsman Dracule Mihawk. Her relationship with Zoro is complex and marked by frequent bickering, such as an incident in which she takes his swords, but it also shows genuine cooperation. In the end, she helps Zoro reach the Sabaody Archipelago so he can rejoin his crew, bringing him there and assisting him with information about Luffy's return.

Her relationship with Gecko Moria is one of the most defining aspects of her character. She views him as a father figure and remains loyal to him even though she is not afraid to criticize his decisions, and her allegiance is tested at times. While she initially considers leaving him after feeling defeated, she ultimately returns to him, showing the depth of their bond.

Perona is also more resourceful than her pampered demeanor suggests. She demonstrates basic medical knowledge when treating Zoro, shows navigation skills during her travels, and is physically capable enough to carry Kumacy's body while levitating with her powers. Over the course of the series, she develops from a self-centered antagonist into a more nuanced figure who is still spoiled and dramatic but also compassionate, loyal, and capable of forming meaningful connections with former enemies.
