The Ope Ope no Mi, a Paramecia-type Devil Fruit from One Piece, gives its user the power to create a spherical “operating room” called the Room, where they can manipulate everything inside with incredible precision. Trafalgar D. Water Law is the current user of this unique fruit, which is often called the “Ultimate Devil Fruit” for its wide range of abilities.
The Ope Ope no Mi, also known as the Op-Op Fruit, is a heart-shaped fruit with a distinctive appearance. It has a vibrant red color with swirly patterns covering its surface. The fruit’s stem resembles a small spike and is often depicted as glowing with an otherworldly light.
Powers and Abilities
Room
The Ope Ope no Mi’s main ability creates a spherical space called the “Room.” Within this field, the user has full control over objects, living beings, and even the environment.
The Room can expand or shrink based on the user’s energy and purpose. Smaller Rooms are perfect for precise tasks, while larger ones are better for wide-area combat or manipulating the surroundings. The sphere is visible, with a blue, semi-transparent boundary, so both those inside and outside can see it. Anything inside the Room is controlled by the user, and this ability is the foundation for all other powers of the Ope Ope no Mi.
Shambles
Shambles allows the user to instantly swap the positions of objects or people within the Room.
This technique is fast and precise, letting the user switch anything, regardless of size or weight. For example, the user could trade a small pebble with a large weapon to create a distraction or confuse an opponent. Shambles also works on living beings, allowing the user to swap positions between enemies or allies.
Amputate
Amputate is a technique that lets the user cut through objects, weapons, or even body parts without causing harm. The severed parts stay functional, and there is no bloodshed. For example, the user can cut off an opponent’s limb to immobilize them while keeping them alive and conscious. This power is effective for neutralizing threats by disabling an enemy without inflicting permanent damage. The user can also reattach severed parts.
Tact
Tact gives the user telekinetic control over objects within the Room. The user can lift, move, or throw them with incredible accuracy.
This ability is so powerful that the user can even move massive objects, like ships. In combat, Tact can be used to throw debris at enemies, create shields by repositioning obstacles, or disarm enemies by pulling weapons away.
Personality Transplant Surgery
The Ope Ope no Mi also allows the user to swap the personalities or souls of individuals through Personality Transplant Surgery. By touching two people inside the Room, the user can exchange their consciousness, effectively putting them in each other’s bodies. This ability can confuse enemies, forcing them to deal with unfamiliar bodies and abilities. The user can reverse the process anytime.
Heart Extraction
One of the most famous abilities of the Ope Ope no Mi is Heart Extraction. This power lets the user remove the “heart” of a living being, which appears as a small, glowing cube. The extraction is painless, and the heart stays functional. The user can control the extracted person by manipulating the heart, and damaging the heart inflicts pain on the original body.
Scalpel
Scalpel is a precise technique that allows the user to remove specific objects or substances from a target. It is especially useful in medical situations, letting the user extract foreign materials, like bullets or toxins, without causing harm. Scalpel can also be used tactically in battle to disable traps or remove weapons stuck inside an enemy.
Counter Shock
Counter Shock is an offensive technique where the user generates electricity and delivers it directly to a target. This attack works like a defibrillator, using a strong jolt to incapacitate opponents.
Radio Knife
Radio Knife is a more advanced version of the cutting abilities granted by the Ope Ope no Mi. This technique combines physical cutting with electrical energy. The user creates an electric blade that can sever objects or living beings. The electric charge makes it harder for the severed parts to reattach, which is especially useful against opponents who can regenerate.
Gamma Knife
Gamma Knife is one of the most destructive techniques available with the Ope Ope no Mi. The user forms a concentrated energy blade that targets and destroys internal organs without leaving any external damage.
This attack bypasses the body’s outer defenses, dealing devastating damage to the inside. Gamma Knife is particularly useful against opponents who are tough enough to withstand regular attacks.
Injection Shot
Injection Shot is a technique where the user delivers fast, precise attacks using a weapon or energy-infused projectiles. This ability is perfect for quick strikes aimed at vital points.
Immortality Surgery
The Immortality Surgery is the most legendary and mysterious ability of the Ope Ope no Mi. This technique allows the user to grant eternal life to another individual, rendering them immune to aging or death from natural causes. However, this procedure comes at the ultimate cost—the life of the user. This one-time-use ability is considered the pinnacle of the Ope Ope no Mi’s powers and a significant reason for its reputation as the “Ultimate Devil Fruit.”
Weaknesses
Stamina Consumption
Using the Room and its abilities drains the user’s stamina. Larger Rooms and advanced techniques require more energy. In prolonged battles, overuse can exhaust the user, leaving them vulnerable.
Skill Dependency
The Ope Ope no Mi’s abilities are not inherently effective without a skilled and knowledgeable user. Many of the fruit’s techniques, particularly its surgical applications, require a high level of precision and understanding. For instance, advanced abilities like Scalpel and Gamma Knife demand medical expertise and a thorough knowledge of anatomy to be used effectively. A less experienced or untrained user may struggle to unlock the fruit’s full potential, rendering its more intricate techniques useless.
Limited Range
While the Room can be expanded to encompass a large area, its range is not infinite and depends on the user’s capabilities. The user’s control is confined to the Room’s boundaries, meaning targets outside of this spherical area are unaffected by the fruit’s powers. Opponents who can move quickly or attack from outside the Room’s range can exploit this limitation, forcing the user to constantly reposition or expand the Room at the cost of additional stamina.
Vulnerability During Use
Creating or expanding the Room, as well as performing complex techniques, requires focus. This moment of concentration can leave the user open to attacks.
Story
The Ope Ope no Mi was previously sought after for its Immortality Surgery. At some point, it was in possession of the World Government, which offered a staggering 5 billion berries for it. The fruit eventually came into the possession of the pirate Donquixote Rosinante (Corazon), who stole it to prevent it from falling into the hands of his brother, Donquixote Doflamingo. Rosinante sacrificed himself to give the fruit to Trafalgar Law.
Awakened Abilities
K-Room (Knife Room)
The K-Room (short for “Knife Room”) is an advanced application where Law envelops his sword, Kikoku, with the properties of the Room. This allows the blade to extend its spatial reach, phase through solid objects, and generate shockwaves upon impact.
R-Room (Remote Room)
The R-Room (Remote Room) allows Law to create smaller, localized Rooms that can attach to targets or objects without requiring him to be physically inside the Room. This innovation enables him to operate remotely, bypassing the limitation of having to stay within the Room’s boundaries.
Anesthesia
Anesthesia is a preparatory technique that Law uses to numb or immobilize an opponent before launching attacks. When combined with K-Room, it enhances his sword-based techniques, ensuring that his strikes are more effective.
Shock Wille
A direct application of K-Room, Shock Wille generates powerful internal shockwaves that cause severe internal damage to enemies. The attack channels destructive energy through the blade into the target’s body, bypassing external defenses.
