One Piece: Captain Shu’s Sabi Sabi no Mi, Very Good’s Beri Beri no Mi, And 5 of the Weakest Paramecia Type Devil Fruits, Ranked

In the realm of Devil Fruits, it’s the Paramecia family that is renowned for bestowing its consumers with some of the most peculiar powers. From inducing earthquakes powerful enough to cleave an island in two, to stealing souls and trapping them inside lifeless objects, or even transforming individuals into toys with a mere touch, users of the Paramecia fruit can perform a variety of unusual feats, many of which are highly dangerous and capable of causing significant harm.

In reality, there are several Devil Fruits of the Paramacia category that many consider to be quite weak and almost ineffective in a genuine battle. To put it simply, here are the 7 weakest combat-focused Paramacia Devil Fruits, arranged based on their weakness. It’s worth noting that this list only concentrates on the combat aspects of these Paramacia fruits; support-oriented fruits such as Mansherry’s Heal-Heal Fruit or Kin’emon’s Garb-Garb Fruit won’t be included in the list.

By rephrasing the original text, I aimed to create a version that is easy to understand and flows naturally.

7. Rust-Rust Fruit

Good Against Blades, Useless Against Others

Japanese Name: Sabi Sabi no Mi
User: Captain Shu
Affiliation: Marine
First Appearance: Episode 309

The Rust-Rust Fruit allows its wielder to accelerate rusting on any metallic item instantly, whether it’s a sword or a ship’s hull. Captain Shu of the Marines, upon obtaining this fruit, could merely touch metal objects and they would dissolve swiftly in his grip. During their encounter at Enies Lobby, he utilized this power to corrupt one of Zoro’s swords, the Yubashiri.

Initially, Captain Shu’s ability may appear potent or beneficial, but upon closer inspection, its significant flaws become apparent. For instance, while Shu can shatter a sword in a matter of seconds, larger objects will take longer to succumb to rust. Additionally, nearly every skilled swordsman in the New World is adept at infusing their blades with Armament Haki. Some of these swordsmen even have the ability to slice their targets without physical contact. Consequently, Captain Shu’s rust power holds little advantage against these skilled opponents.

6. Berry-Berry Fruit

A Weaker Version of Buggy’s Power

Japanese Name: Beri Beri no Mi
User: Captain Very Good
Affiliation: Marine
First Appearance: Episode 309

Observing closely, it appears that the Berry-Berry Fruit grants its user, in this case, Captain Very Good of the Marines, an extraordinary ability. Instead of maintaining a single form, they can transform their body into multiple round entities, reminiscent of berries. With this transformation, they possess an impressive control over these spherical parts, capable of propelling them forcefully towards an adversary, much like a cannonball would be launched.

The Berry-Berry Fruit, in comparison, is a less potent version of Buggy’s signature Chop-Chop Fruit. Both fruits grant their users the ability to divide various body parts, but unlike Buggy who maintains the integrity of his body shape, Captain Very Good’s body transforms into spherical forms. This difference means that Buggy can separate his hand and use it to strangulate enemies from a distance, a feat that Captain Very Good cannot accomplish. While Captain Very Good is able to hurl his transformed body parts like a cannonball, if an enemy captures these parts, Captain Very Good effectively loses those specific body parts.

5. Spin-Spin Fruit

Barely Fly, Barely Strike

Japanese Name: Guru Guru no Mi
User: Buffalo
Affiliation: Donquixote Pirates
First Appearance: Episode 618

With Spin-Spin Fruit, the user from the Donquixote Pirates, known as Buffalo, can transform various parts of his body and attire into spinning propellers. Whether it’s his hair or socks, he has the power to spin them freely, adjusting the speed and direction at his will. In most cases, Buffalo uses this ability to spin his hair, turning himself into a makeshift plane for his crewmates, serving as a means of transportation. For defensive purposes, he rapidly spins his fist or even his head when necessary, charging towards enemies with great force.

A seemingly powerful ability that includes flight or a spinning punch might appear strong and versatile at first glance. However, this couldn’t be more misleading. While Buffalo can indeed fly, his speed and agility in mid-air are significantly restricted. Similarly, his spinning punch lacks substantial force. Skilled fighters in the New World would effortlessly dodge or even retaliate against Buffalo’s feeble attacks.

4. Mark-Mark Fruit

An Easy-to-Counter Homing Missile

Japanese Name: Mato Mato no Mi
User: Vander Decken IX
Affiliation: Flying Pirates
First Appearance: Episode 525

Mark-Mark Fruit empowers user Vander Decken IX of the Flying Pirates to effortlessly hit his chosen target at any given time or place, using any item he chooses to throw. By simply marking a target with his hand, Vander Decken is able to launch objects in any direction; they will adjust themselves instinctively and home in on the marked target without needing any prior knowledge of its location. This remarkable power allows whatever is thrown to continuously fly towards the precise spot where the target currently resides, even if it’s moving. In essence, the object behaves like a guided missile that persistently tracks and follows its designated target.

Although the Mark-Mark Fruit’s lethal projectile might appear ideal for an assassin, it can be effectively countered in various ways. Firstly, the thrown object comes to a halt when it collides with something, not necessarily the intended target. For instance, if it gets lodged in a wall, a shield, or any obstacle that alters its path, those projectiles will no longer persist in pursuing the target. Secondly, even moderately powerful combatants can divert the trajectory of the thrown objects, causing them to cease chasing the target. Furthermore, since Vander Decken relies on his hands to hurl these deadly objects, if an adversary manages to bind his hands, break them, or worse, sever them, this ability becomes ineffective.

3. Pile-Pile Fruit

A Power That Requires Other People’s Help

Japanese Name: Gocha Gocha no Mi
User: Charlotte Newshi
Affiliation: Big Mom Pirates
First Appearance: Episode 822

Using Pile-Pile Fruit, Charlotte Newshi from the Big Mom Pirates can combine her body with others, resulting in a transformation where she becomes a new entity that’s larger and more powerful than her original self. The composition of individuals involved and their individual strength significantly influence the final form’s size and power. As one of the renowned Charlotte Decuplets, Charlotte Newshi often combines with her nine siblings, resulting in a massive, scythe-wielding monster.

A combat devil fruit that necessitates the participation of others to be effective is essentially worthless. Additionally, Newshi can’t forcibly merge with any random bystander; he needs their agreement. Consequently, he always merges with his twins. This implies that when his twins are not present, Charlotte Newshi is once again rendered completely useless.

A devil fruit used in combat that relies on others to function properly is essentially worthless. Furthermore, Newshi cannot forcibly merge with anyone he chooses; he needs their permission. Therefore, he only merges with his twins. As a result, when his twins aren’t around, Charlotte Newshi is once again rendered completely useless.

2. Wheel-Wheel Fruit

An Embarrassingly Weak Devil Fruit

Japanese Name: Shari Shari no Mi
User: Captain Sharinguru
Affiliation: Marine
First Appearance: Episode 310

Should Buffalo’s Spin-Spin Fruit allow Buffalo to transform various body parts into spinning propellers, Captain Sharinguru of the Marines, with his Wheel-Wheel Fruit, can twist different body sections like wheels. Primarily, this devil fruit empowers him to spin his arms and legs rapidly, utilizing these swiftly rotating limbs to dash towards his adversaries in a powerful charge.

In the narrative, Captain Sharinguru entered during the conclusion of the Enies Lobby arc. In that instance, he transformed his limbs into rapid wheels and rushed towards Franky. However, it was just one arm from Franky (pre-time skip, before he incorporated Vegapunk’s technology) that managed to halt the captain and his spinning limbs in their tracks. Thus, even though the Straw Hat’s DIY cyborg was able to stop this captain with a single arm, it’s clear that the power of his Devil Fruit is quite feeble.

1. Jacket-Jacket Fruit

A Weak, Useless, and Pathetic Devil Fruit

Japanese Name: Jake Jake no Mi
User: Kelly Funk
Affiliation: Mogaro Kingdom
First Appearance: Episode 645

The enchanting Jacket-Jacket Fruit bestows upon Kelly Funk of the Mogaro Kingdom an extraordinary ability: he can transform into a full-body suit, essentially a sentient jacket. If another individual chooses to don this unique apparel, Kelly gains control over their body. It’s safe to say that no sane person would desire a living jacket resembling human skin and adorned with a conversing human face.

To avoid such peculiar situations, Kelly often travels accompanied by his brother, Bobby Funk, who graciously agrees to wear his brother as a jacket.

Although Kelly is small in stature, he’s an accomplished boxer with no fear of confrontation. In contrast, Bobby is tall and muscular but lacks confidence and often fears challenges. When Kelly, metaphorically speaking, finds himself in the role of a jacket worn by Bobby, he suddenly inherits Bobby’s physique and strength that complement his boxing abilities and bold personality.

It’s clear that this devil fruit from One Piece is among the most bizarre, if not the absolute strangest. Who in their right mind would want to don a human coat? This implies that Kelly can only activate his Devil Fruit abilities with his brother. A devil fruit whose power depends on another specific individual is essentially worthless. To make matters worse, their combined powers aren’t particularly impressive. Even experienced fighters in the New World could easily overpower them. In essence, the Jacket-Jacket Fruit is not only weak, but it also appears repulsive and woefully ineffective in a real fight scenario. That’s why it rightfully earns the title of the weakest Paramecia Devil Fruits in One Piece.
