One Piece Devil Fruit Guide: One-Shot Builds (2026)

Devil Fruits have always been the engine behind One Piece power scaling—mystical abilities born from human imagination, with the tradeoff of losing the ability to swim. And while most fruits are fearsome on their own, some are portrayed as so overwhelming they can end a fight in a single strike.

The “too powerful to survive” Devil Fruits

The story establishes that Devil Fruits grant their eaters extraordinary capabilities, yet also follow a rule: the more incredible the power, the more dangerous the cost. That idea is reinforced by Vegapunk, who confirms that Devil Fruits originate as an alternate form of evolution tied to human imagination.

Within that framework, the following Devil Fruits are framed as being on a higher tier—fruits that are believed to be capable of killing anyone with one shot, or at least doing so under the right conditions.

10 Mero Mero no Mi

Type: Paramecia
User: Boa Hancock

The Mero Mero no Mi is used by Boa Hancock, the Pirate Empress. It lets Hancock petrify anyone in her path, with the effect especially tied to people drawn to her. However, the fruit’s use is not limited to attraction—it can also turn inanimate objects to stone.

Hancock only needs a single touch to trigger petrification. If she hits someone with “Mero Mero Mellow,” the target can be turned into stone immediately. Only Hancock can reverse that petrification, and the power is so severe that even Teach, a Yonko, feared it and couldn’t undo the effect.

9 Magu Magu no Mi

Type: Logia
User: Sakazuki

The Magu Magu no Mi is a Logia Devil Fruit consumed by the new Fleet Admiral Sakazuki. It’s described as one of the most overpowered fruits, with an emphasis on its extreme offensive potential. With this Devil Fruit, he can transform into magma, create it, and manipulate it at will.

Because of that control, Sakazuki can flood opponents with magma and kill in a single shot. In the fight against Ace, Akainu demonstrated that he could kill with one clean hit.

8 Goro Goro no Mi

Type: Logia
User: Enel

Goro Goro no Mi is presented as one of the rare Devil Fruits said to be invincible. As a Logia ability, the user can become, as well as produce and control lightning at will.

The fruit is claimed to have enough destructive power to wipe out an entire island without even awakening. It can easily kill most characters in One Piece in a single shot, which is why it’s treated as such a dangerous ability.

7 Doku Doku no Mi

Type: Paramecia
User: Magellan

Eaten by Magellan, the former Warden of Impel Down, the Doku Doku no Mi lets him manipulate poisons. The fruit is described as especially lethal, granting control over millions of toxin types that he can handle however he wants.

It’s framed as both a standout ability and a fatal one. During the Impel Down arc, it’s said it could have killed Luffy with a single shot, and it could have wiped out the entire Blackbeard crew in one strike—if they hadn’t received an antidote.

6 Ope Ope no Mi

Type: Paramecia
User: Trafalgar Law, Unknown Doctor From The Void Century

The Ope Ope no Mi is used by Trafalgar Law, the “Surgeon of Death,” and is presented as one of the most overpowered powers in the world of One Piece. The fruit allows Law to operate on anyone inside the “ROOMs” he creates.

Inside his ROOM, everything is treated like a patient on an operating table, and Law can even reshape the terrain as he chooses. With strong combat capabilities within his ROOMs—and now that his Devil Fruit has awakened—it’s claimed he can kill in a single shot using techniques like Puncture Wille.

A new Devil Fruit straight from hell has also been officially revealed in One Piece’s latest release of the Elbaf arc.

5 Gasu Gasu no Mi

Type: Logia
User: Caesar Clown

The Gasu Gasu no Mi is a powerful Logia introduced to fans during the Punk Hazard Arc through Caesar Clown. It allows Caesar to turn into, produce, and manipulate gases freely.

Caesar could remove oxygen from smaller spaces. The fruit is described as potentially deadly in the hands of a better user, and it’s said to be able to kill anyone in one shot via oxygen removal—making it one of the most dangerous powers in existence.

4 Soru Soru no Mi

Type: Paramecia
User: Former Yonko Big Mom

Eaten by Big Mom, the former Emperor of the Sea, the Soru Soru no Mi is described as among the most dangerous abilities introduced in One Piece. It lets the user manipulate souls in whatever way they want, including ripping out a soul or, in certain cases, taking away part of an enemy’s lifespan with a single shot.

It can kill targets who have little life left. Still, depending on Big Mom, some can survive the ability. The effect is also tied to fear—this power only works if the target fears the user. Since Big Mom wields it, the majority of people in the world are said to fear her, making the fruit’s impact widespread. On top of that, the Devil Fruit is said to include additional capabilities that give Big Mom enough power to kill nearly anyone in a single shot.

3 Gura Gura no Mi

Type: Paramecia
User: Blackbeard, Whitebeard (former)

The Gura Gura no Mi is widely known as the strongest Paramecia-class Devil Fruit. It allows the user to generate vibrations, which can then be routed through the ground, the air, or any other medium—making the user, in effect, a “vibration man.”

This Devil Fruit is used to create devastating quakes and even trigger tsunamis. It’s described as so catastrophic it could destroy the entire world, a level of threat compared to the Ancient Weapons. Because of that, it’s easy to see why the fruit is treated as a “kill in one shot” contender.

2 Ryu Ryu no Mi, Model: Nidhoggr

Type: Zoan
User: Loki

The Ryu Ryu no Mi, Model: Nidhoggr is a Mythical Zoan Devil Fruit wielded by Loki, the Accursed Prince of Elbaf. It’s described as legendary and said to have been passed down through Elbaf’s royal bloodline for generations—until 14 years ago, when Loki ate it.

The fruit’s powers allow Loki to transform into the world’s largest dragon, known as Nidhoggr, which can produce lightning. The lightning is claimed to be strong enough to destroy the entire world. With abilities such as Thorheim, the user is said to be able to kill practically anyone in a single shot, and with repeated use, even countries can be left utterly destroyed.

1 Akuma no Mi

Type: Unknown
User: Nerona Imu

Officially introduced in One Piece Chapter 1179, the Akuma no Mi is a unique Devil Fruit. With no known classification, it’s described as among the strongest in the entire world—allowing its user, Nerona Imu, to transform into the Devil God from the One Piece universe.

Using powers such as Demonic Contracts, it can turn anyone into demonic slaves. It also enables control over a distinct ability referred to as Omen or Maki. The firepower of this Omen is said to be so extreme that most people can die in a single hit, and its capabilities are described as unmatched.
