Devil Fruits come in all shapes and sizes, holding powers that, according to Vegapunk, represent humanity’s evolutionary possibilities. These special fruits can offer anything from superhuman abilities to life-changing physical transformations. All it takes is a single bite. In One Piece, many of the strongest characters take advantage of their Devil Fruit powers to travel across the high seas.
Unfortunately, given the variety of Devil Fruits in the world, it makes sense that some wouldn’t be picturesque or particularly attractive. In fact, some of them are downright nasty, transforming the user’s body in weird ways or manifesting in a truly disgusting fashion. While their powers may be useful or extremely powerful, they may not be worth having because they’re so gross.
9 Venom-Venom Fruit
The Fruit With The Worst Stomach Problems
It could be said that the Venom-Venom Fruit is extremely powerful since it makes the user immune to poison while also letting them produce and control it. This poison is potent enough to kill someone outright through the simplest forms of contact. However, it does come with a very specific, strange weakness.
Despite being immune, the user is unable to digest or process ingested poisons, leaving them with harsh bowel movements that keep them in the restroom for hours at a time. The simplest solution would be not to eat poisoned food, but some Devil Fruits come with odd habits. Eating poison could just be part of the Venom-Venom Fruit, leaving the user to suffer from some extreme IBS.
8 Memo-Memo Fruit
An Awkward Power To Use
In practice, the Memo-Memo Fruit has some incredible utility. Being able to manipulate the memories of any person would provide the user with many advantages, especially when it comes to information gathering and espionage. Pudding was able to make great use of her Devil Fruit during the Whole Cake Island arc.
The power of the Memo-Memo Fruit is actually quite appealing, since memories are represented as strips of film. The gross part of this ability is the way it’s activated. In the One Piece world, it may be normal, but for most people, reaching into someone’s head is quite awful. However, this is one of the more tame forms of body horror in the story.
7 Brain-Brain Fruit
Making "Big Brain" Literal
Part of the reason why Vegapunk is such a genius is his Devil Fruit. The Brain-Brain Fruit allows the user to infinitely store information and recall it perfectly. Essentially, Vegapunk has a super photographic memory, meaning he always has the information he needs when he needs it. It’s incredibly useful.
However, the more the user learns, the more their brain grows. Eventually, the brain grows so much that the user’s head needs to expand to contain it, resulting in a gross physical distortion. Vegapunk’s brain contained so much information that he had to chop the top of his head off and create a cloud system to hold it all.
6 Swamp-Swamp Fruit
As Dirty As Mud
Logia Devil Fruits are usually cool and interesting, transforming the user’s body into a type of natural element or substance. The Swamp-Swamp fruit is much less iconic, as it basically turns the user into a walking pile of mud. It’s pretty strong as the user is a living sinkhole that can absorb anything, even entire buildings.
Swamps and mud can generally be seen as gross or messy, but this Devil Fruit’s reputation is exacerbated by its current user, Caribou, who is quite an unsavory character. Due to his greasy appearance and wicked demeanor, he definitely gives his fruit a bad name.
5 Bomb-Bomb Fruit
The Booger Blaster
The power of the Bomb-Bomb Fruit isn’t inherently gross. It has the potential to be incredibly destructive while keeping the user completely safe. With the power to turn any body part or body product into a bomb, the user should be able to end most fights immediately.
Unfortunately, this Devil Fruit was portrayed in the grossest way possible. The current user, Mr. 5 (aka Gem), used his powers to turn boogers into bombs and fling them at his opponents. It’s meant to be a joke, but it’s also one of the nastiest ways to use a Devil Fruit.
4 Flower-Flower Fruit
One Too Many Hands
Although Nico Robin uses her Devil Fruit quite elegantly, the concept of the Flower-Flower Fruit is quite disturbing. This Devil Fruit allows the user to sprout their body parts on any physical surface like a flower. That means the user can make their legs, arms, hands, and feet appear almost anywhere.
Naturally, it would be pretty unsettling to see disembodied limbs hanging from the walls or jutting out from the floor. It’s even worse thinking about other body parts like ears, eyes, and noses randomly sticking to places they shouldn’t be. The anime makes this power look charming, but the reality is terrible.
3 Jacket-Jacket Fruit
Getting Underneath Someone's Skin
One of the most controversial Devil Fruits to appear in the series is the Jacket-Jacket Fruit. Since its debut, fans have wondered who would ever want the ability to turn into someone else’s clothing. This fruit’s power allows the user to take control of whoever is wearing it, giving them access to that person’s abilities.
In theory, it’s an interesting ability, but the way it’s presented is horrendous. The user basically becomes a literal skin suit with a zipper, and they can be worn like a big onesie. This is probably one of the worst examples of body horror in One Piece.
2 Mucus-Mucus Fruit
Slime And Snot
Not much needs to be said about the Mucus-Mucus Fruit. As its name implies, it allows the user to create and manipulate mucus, which actually has some good combat uses, but that doesn’t excuse the sheer grossness of this Devil Fruit. Mucus is probably one of the worst substances to control.
The current user, Trebol, doesn’t do this power any favors by wearing his mucus as clothing. While this may give him an edge in combat, it’s a pretty disgusting thing to do every single day. This Devil Fruit may also cause the user to have a constant runny nose and to always be congested, which is a terrible way to live.
1 Sick-Sick Fruit
An Eternally Ill Patient
The grossest Devil Fruit is the Sick-Sick Fruit by a large margin. It gives the user the ability to create and infect people with diseases. While not much is known about this power, it can create sicknesses that change people’s genders, so it must be capable of much worse as well.
This Devil Fruit also has one of the worst side effects of any power. The eater enters a state of constant sickness, and anyone they come in contact with also becomes sick. Being ill can feel pretty gross, so having to live like that forever must be pretty terrible.
