Among the three families of Devil Fruits, the Paramecia is known to be the type of Devil Fruit that grants the strangest abilities to its users. From causing an earthquake that can split an island in half to snatching people’s souls and placing them into inorganic objects to turning people into toys with a single touch, the Paramecia users can do all sorts of strange things, most of which are incredibly dangerous and can inflict a lot of damage.
One Piece: 7 Best Devil Fruits That Aren't for Fighting
The following Devil Fruits from One Piece aren't particularly suited for combat, but they still have incredible and practical uses.
There are, however, quite a few Paramecia Devil Fruits that are not only considered weak but are also borderline useless in a real fight. So with that in mind, here are the 7 weakest Paramecia-type Devil Fruits, ranked based on how weak they are. Keep in mind that this list focuses solely on combat-type Paramecias. This means support-type Paramecias, like Mansherry’s Heal-Heal Fruit or Kin'emon’s Garb-Garb Fruit, won’t be on the list.
Rust-Rust Fruit
Good Against Blades, Useless Against Others
- Japanese Name: Sabi Sabi no Mi
- User: Captain Shu
- Affiliation: Marine
- First Appearance: Episode 309
Rust-Rust Fruit enables its user to cause any metallic object, be it a sword or the hull of a ship, to rust instantaneously. As the user of this fruit, Captain Shu of the Marine can simply touch any metallic object, and it will immediately disintegrate in his hands. In fact, that was precisely what he had done to one of Zoro’s swords, the Yubashiri, when they fought at Enies Lobby.
This ability might seem powerful, or at least useful, at first glance, but the deeper you look into it, the more you’ll notice its glaring weakness. First of all, while Captain Shu can crumble a sword in seconds, large objects will take longer to rust. Second of all, almost every swordsman worth their salt in the New World can coat their blade with Armament Haki. Some are even able to slice their target without having to touch it. Shu’s rust power is basically useless against this type of swordsman.
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
Berry-Berry Fruit enables the user to turn his body into numerous spherical objects, sort of like berries. As the user of this devil fruit, Captain Very Good of the Marines can freely control his spherical body parts and launch them towards his opponent at high speed, sort of like a cannonball.
Berry-Berry Fruit is essentially a weaker version of Buggy’s iconic Chop-Chop Fruit. Both enable their users to separate parts of their bodies, but unlike Buggy, who retains the overall shape of his body parts, Very Good’s body turns into balls. This means Buggy can separate his hand and use it to choke his enemy from afar, but Very Good can’t do such a thing. Sure, Very Good can launch his body parts like a cannonball, but if the enemy manages to capture them, this Marine Captain will essentially lose those body parts.
Spin-Spin Fruit
Barely Fly, Barely Strike
- Japanese Name: Guru Guru no Mi
- User: Buffalo
- Affiliation: Donquixote Pirates
- First Appearance: Episode 618
Spin-Spin Fruit enables its user, Buffalo of the Donquixote Pirates, to turn any part of his body and his clothing into propellers. Be it his hair or his socks, he can rotate them at will and freely control the speed and direction of the rotation. Buffalo mainly uses this ability to rotate his hair and basically turn himself into a propeller plane, basically a mode of transportation for his crewmates. For offensive purposes, he often rotates his fist and sometimes his head at high speed, and charges at his enemy.

An ability that allows its user to fly or perform a rotating punch might seem like a strong and versatile power. But that couldn’t be further from the truth. Though Buffalo can fly, his speed and maneuverability are highly limited. His high rotation punch also barely has any power behind it. Any seasoned fighters in the New World could easily evade or even counter Buffalo’s puny attacks.
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 enables its user, Vander Decken IX of the Flying Pirates, to accurately hit his target anywhere, anytime, and with anything. Once he marks a target with his hand, Vander Decken can throw anything in any direction, and it will automatically correct itself to home in on the marked target. He doesn’t even need to know about the target’s current whereabouts. Thanks to this power, the object that he throws will always fly towards the target’s precise location. Even if the target happens to be on the move, it will still follow like a homing missile.
The Mark-Mark Fruit might seem like the perfect ability for an assassin, but there are actually numerous ways to counter this ability. First of all, the thrown object will stop once it “arrives” at something, and it doesn’t have to be the target itself. This means if it gets stuck in a wall, or a shield, or anything that may hinder its trajectory, those thrown objects will no longer pursue the target. Second of all, any reasonably strong fighters can simply knock the thrown objects off course, and it will also stop chasing the target. Besides, since Vander Decken needs to use his hands to throw, if the enemy manages to tie his hands up, or break them, or worse, cut them off, then this ability will be useless.
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
Pile-Pile Fruit enables its user, Charlotte Newshi of the Big Mom Pirates, to merge his body with other people. Once merged, Newshi will become a new person who is bigger and stronger than his original body. However, the number of people and the strength of each individual will greatly affect the size and the power of the final transformation. Since Charlotte Newshi is one of the infamous Charlotte Decuplets, he usually merges with his nine twins, which results in a giant, scythe-wielding monster.
Any combat-type devil fruit that requires other people’s involvement in order to use it is utterly useless. Not only that, Newshi can’t just forcefully merge with a random passerby. He needs their consent. That’s why he always merges with his twins. That means when his twins are not around, Charlotte Newshi is, once again, utterly useless.
Wheel-Wheel Fruit
An Embarrassingly Weak Devil Fruit
- Japanese Name: Shari Shari no Mi
- User: Captain Sharinguru
- Affiliation: Marine
- First Appearance: Episode 310
If Buffalo’s Spin-Spin Fruit enables Buffalo to turn any part of his body into propellers, the Wheel-Wheel Fruit enables Captain Sharinguru of the Marines to rotate any part of his body like a wheel. The captain mainly uses this devil fruit to rotate his arms and legs at high speed and use those rotating limbs to charge at his opponents.
7 One Piece Characters Who Should Never Have Become Marines
These characters may be part of the Marines, but none of them should’ve joined this institution in the first place.
Captain Sharinguru appeared in the story at the end of the Enies Lobby arc. At the time, he turned his limbs into high-speed wheels and charged at Franky. Franky stopped him with his right arm. Keep in mind that it was Franky before the time skip, way before he augmented his body with Vegapunk’s techs. Yet a single arm is all it took for the Straw Hat’s DIY cyborg to stop the poor captain and his rotating limbs. So, as you can see, this devil fruit is embarrassingly weak.
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
Jacket-Jacket Fruit enables its user, Kelly Funk of the Mogaro Kingdom, to turn into a jacket, or to be more precise, a full-body suit. If anybody agrees to wear him as a jacket, Kelly will be able to control that person's body. Needless to say, nobody in their right mind would want to wear a jacket that looks like a human skin and has a talking human face. That’s why Kelly usually travels together with his brother, Bobby Funk, who is willing to wear his brother as a jacket.
Kelly is a short man, but he has proper boxing skills and is not afraid to pick a fight. Bobby, on the other hand, is a towering man with a buff body, but he is timid and gets scared easily. When Bobby wears Kelly as a jacket, Kelly finally gets the body and the strength that can match his boxing skills and his brazen attitude.
As you can see, this is one of the most, if not the most, outrageous devil fruits in One Piece. Again, nobody in their right mind would want to wear a human jacket. This means Kelly can only utilize his Devil Fruit power with his brother. A devil fruit that requires one other specific person to use is basically useless. Not only that, but their combined powers are also not that impressive. Any seasoned fighters in the New World can easily knock them down. So in summary, the Jacket-Jacket Fruit is not only weak, but it also looks repulsive and devastatingly useless in a real combat situation. That’s why it deserves the title of the weakest Paramecia Devil Fruits in One Piece.
