The Horo Horo no Mi (Hollow-Hollow Fruit) is one of the most unique and psychologically devastating Paramecia-type Devil Fruits in the entire *One Piece* universe, granting its user the power to produce and control ghosts. As of the current storyline in late 2025, the fruit’s primary user, Perona, has resurfaced in major, high-stakes events, proving that her seemingly whimsical ability remains a critical factor in the New World’s power struggles. The fruit's true lethality lies not in physical strength, but in its ability to instantly incapacitate even the strongest opponents by weaponizing extreme despair.
Consumed by the "Ghost Princess" Perona, this Devil Fruit allows her to become a "Ghost Human" (霊体人間, Reitai Ningen), transforming her into a master of spectral warfare. While initially introduced during the Thriller Bark Arc as a comedic foil to the Straw Hat Pirates, recent manga developments have placed Perona and her fruit at the center of a major conflict involving the Blackbeard Pirates and the fate of her former master, Gecko Moria. Understanding the Horo Horo no Mi is essential to grasping the full scope of its strategic and combat potential.
Ghost Princess Perona: A Brief Biography and Profile
The Horo Horo no Mi is intrinsically tied to its user, Perona, whose gothic aesthetic and dramatic personality perfectly complement the fruit’s spooky powers. Her journey from a subordinate of one of the Seven Warlords to a temporary resident of the World's Strongest Swordsman's castle is a testament to her tenacity, and her latest appearance confirms her unwavering loyalty.

The Horo Horo no Mi's Destructive Capabilities: More Than Just Depression
The core ability of the Horo Horo no Mi is the creation of "Hollows," which are spectral, ghost-like beings that Perona can control. These are not just simple illusions; they are potent weapons with diverse applications in battle, reconnaissance, and even defense. The fruit’s powers can be categorized into three main forms of spectral manipulation.
1. The Lethal "Negative Hollows"
This is the Horo Horo no Mi's most famous and devastating technique. Perona can create small, floating ghosts that pass directly through an opponent's body. Upon contact, the victim is instantly overwhelmed by an intense, crippling wave of negativity and despair.
- The Effect: Victims immediately fall to their knees, lamenting their existence and apologizing for every failure in their life. They are rendered completely unable to fight or even move for an extended period.
- The Combat Advantage: This ability offers an instant, non-physical form of crowd control. It can neutralize a large group of powerful fighters simultaneously, regardless of their physical strength or Haki level, making it one of the most broken abilities in the series.
- The Weakness: The only known immunity comes from individuals who are already inherently pessimistic or negative, as demonstrated by Usopp, whose natural state of despair countered the ghost’s effect.
2. The Ghost Projection (Out-of-Body Experience)
Perona can separate her own consciousness from her physical body and transfer it into a spectral form. This ability is a game-changer for stealth and defense.
- Intangibility: In her ghost form, Perona is completely intangible. Physical attacks, including those imbued with Busoshoku Haki, pass harmlessly through her.
- Reconnaissance: She can fly through walls and cover vast distances quickly, making her an unparalleled spy and scout.
- The Vulnerability: While her ghost form is invulnerable, her physical body remains unconscious and exposed. This is the fruit’s greatest tactical weakness, requiring her to hide her body in a secure location during combat.
3. The Explosive "Mini Hollows"
Perona can also produce large, balloon-like ghosts that she can detonate on command. These are used for area-of-effect damage, providing a more direct, offensive capability to an otherwise purely psychological fruit.
The Horo Horo no Mi's True Potential: Haki, Awakening, and Strategic Value
Despite the fruit's immense psychological power, its effectiveness in the New World is often debated, primarily due to the introduction of advanced Haki.
Can Haki Counter Negative Hollows?
The general consensus among fans and analysts is that Busoshoku Haki (Armament Haki) cannot defend against the Negative Hollows. Haki allows a user to physically touch and strike an intangible Devil Fruit user (like a Logia), but the Negative Hollows are not a physical attack. They are a psychological wave that passes through the body, affecting the mind and spirit. A strong will, perhaps reinforced by Haoshoku Haki (Conqueror's Haki), might allow a user to resist the despair, but the initial contact effect is nearly impossible to block.
This unique nature is why the Horo Horo no Mi is often considered a "Hax" (a broken or overpowered) ability, as it bypasses the conventional strength hierarchy of the *One Piece* world. Even a Yonko-level fighter would be momentarily incapacitated, creating a crucial opening for an ally to strike.
The Hypothetical Awakening
Like all Paramecia fruits, the Horo Horo no Mi is theorized to have an Awakening. A common theory suggests that an Awakened user could transform their surroundings into ghosts or spectral matter. This could allow Perona to:
- Turn the ground into a massive, intangible ghost to phase through enemy attacks.
- Create an entire army of autonomous, despair-inducing Negative Hollows from the environment itself.
- Turn objects into temporary ghosts, making them immune to damage.
Perona's Latest Manga Appearance: The Current Status of the Horo Horo no Mi
In a major, recent development in the *One Piece* manga, Perona's loyalty to Gecko Moria was highlighted, bringing the Horo Horo no Mi back into the spotlight. Following the events of the Wano Country Arc, Perona was last seen in a precarious position.
The Hachinosu Infiltration: Perona was shown infiltrating Hachinosu (Pirate Island), the base of the Blackbeard Pirates, who had captured Gecko Moria. This bold move was driven by her desire to free her former captain. She even approached Koby of the Marines, a known enemy, to negotiate his help in exchange for her own freedom, demonstrating a high level of strategic thinking and desperate resolve.
This reappearance confirms that Perona is currently operating in one of the most dangerous locations in the New World. The Horo Horo no Mi's abilities—stealth, the ability to pass through walls, and the instant neutralization of powerful foes—make it the perfect tool for infiltration and rescue operations against formidable opponents like the Blackbeard Pirates.
The Horo Horo no Mi, therefore, is far from a joke fruit. It is a psychological weapon of mass incapacitation, currently being wielded by a determined and loyal operative in a critical, high-stakes conflict. Its power to bypass conventional strength will ensure Perona and the Ghost Princess remain relevant figures in the final saga of *One Piece*.
