9 Darkest Abilities in One Piece: Unveiling the Depths of Darkness

One Piece is a popular manga and anime series that features a world of pirates, marines, and supernatural powers. The main source of these powers is the Devil Fruits, mysterious fruits that grant users various abilities, such as transforming into animals, manipulating elements, or altering their bodies.

However, not all Devil Fruits are benign or beneficial. Some of them have dark and sinister effects that can cause harm to others or even themselves. This article will explore some of the darkest abilities in One Piece, ranked from least to most terrifying.

9. Defective SMILE Devil Fruits

The defective SMILE Devil Fruits are artificial Zoan-type fruits created by Caesar Clown and Donquixote Doflamingo. They are supposed to allow users to transform into animals, but only a small fraction work properly.

The rest of them have a horrifying side effect: they make the consumers unable to express emotions other than joy. Even in the most tragic situations, they can only smile and laugh, losing their sense of self and dignity. Kaido used the defective SMILE fruits to create an army of mindless soldiers known as the Gifters.

8. Shibo Shibo no Mi

The Shibo Shibo no Mi is a Paramecia-type Devil Fruit that allows users to extract liquids from anything they touch. It was eaten by Charlotte Smoothie, one of the Sweet Commanders of the Big Mom Pirates. With this ability, Smoothie can squeeze out juice from objects, animals, or people, and either drink it herself or store it in containers.

She can also use the liquid to increase her size and strength or create weapons. This ability is dark because it can cause severe dehydration and death and destroy living beings’ physical integrity.

7. Hobi Hobi no Mi

The Hobi Hobi no Mi is a Paramecia-type Devil Fruit allowing users to turn anyone they touch into a toy. Sugar, an officer of the Donquixote Pirates, ate it. With this ability, Sugar can transform people into various types of toys and erase their memories from everyone else’s minds.

She can also give orders to the toys they must obey without question. The only way to reverse the effect is to make Sugar lose consciousness or die. This ability is dark because it strips people of their identity and freedom, and makes them into playthings for Sugar’s amusement.

6. Soru Soru no Mi

The Soru Soru no Mi is a Paramecia-type Devil Fruit allowing users to manipulate souls. It was eaten by Charlotte Linlin, also known as Big Mom, one of the Four Emperors of the Sea. With this ability, Big Mom can steal fragments of people’s lifespans and use them to create homies, living creatures made from objects, animals, or natural phenomena.

She can also transfer souls between homies or people, or even infuse her soul into objects to create powerful weapons. The process of stealing lifespans is based on fear: if the victim fears Big Mom, they will lose more years of their life. This ability is dark because it deprives people of their free will and longevity, making them slaves or tools for Big Mom’s whims.

5. Yami Yami no Mi

The Yami Yami no Mi is a Logia-type Devil Fruit that allows the user to create and control darkness. Marshall D. ate it Teach, also known as Blackbeard, was one of the most notorious pirates in the world. With this ability, Blackbeard can create a sphere of darkness with a strong gravitational pull, sucking in everything around it and crushing it with immense pressure.

He can also use the darkness to nullify the powers of other Devil Fruit users by touching them, making them vulnerable to physical attacks. The darkness also has the property of absorbing damage, allowing Blackbeard to endure more pain than normal. This ability is dark because it represents the evil and destructive nature of Blackbeard, who seeks to become the Pirate King by any means necessary.

4. Ice Oni Virus

The Ice Oni Virus is not a Devil Fruit power, but a biological weapon created by Caesar Clown, a former scientist of the World Government who became a criminal mastermind. The virus is spread through bullets that inject it into the bloodstream of the victims.

The virus causes the body temperature of the infected to drop rapidly, turning them into ice zombies that attack anyone nearby with icy claws and breath. The only way to cure the virus is to heat the body enough to melt the ice crystals in the veins, which requires fire or strong willpower. The virus is dark because it turns people into mindless monsters that endanger themselves and others.

3. Ope Ope no Mi

The Ope Ope no Mi is a Paramecia-type Devil Fruit that allows users to create a spherical space to manipulate anything. It was eaten by Trafalgar Law, a former member of the Donquixote Pirates and a current ally of Monkey D. Luffy, the protagonist of One Piece.

With this ability, Law can perform various operations on objects or people, such as cutting, swapping, shuffling, or extracting. He can also use the power to cure diseases or grant eternal youth to someone, at the cost of his own life. This ability is dark because it can cause severe damage or death to living beings and violate their physical and mental integrity.

2. Toki Toki no Mi

The Toki Toki no Mi is a Paramecia-type Devil Fruit that allows users to travel forward in time. It was eaten by Kozuki Toki, the wife of Kozuki Oden and the mother of Kozuki Momonosuke and Kozuki Hiyori. With this ability, Toki could send herself or others to the future by opening a portal in the air.

She could also choose how far into the future she wanted, up to 20 years. However, she could not return to the past, making it a one-way trip. This ability is dark because it involves leaving behind everything and everyone in the present and facing an uncertain and possibly dangerous future.

1. Kage Kage no Mi

The Kage Kage no Mi is a Paramecia-type Devil Fruit that allows the user to manipulate shadows. It was eaten by Gecko Moria, a former member of the Seven Warlords of the Sea and an enemy of Monkey D. Luffy. With this ability, Moria can detach his shadow or steal shadows from others using scissors. He can then use the shadows to create zombies by inserting them into corpses or other objects.

He can also fuse multiple shadows to create giant monsters or enhance his body. The shadows retain some of the personality and skills of their original owners but are loyal to Moria. The drawback of this ability is that the shadowless victims will die if exposed to sunlight, and the zombies will also be destroyed. This ability is dark because it violates the natural order of life and death, and enslaves the souls of the living and the dead.


These are some of the darkest abilities in One Piece that have been shown to cause great suffering and horror to their victims or users. They range from manipulating souls, shadows, and ghosts, creating zombies, ice onis, and defective SMILEs, extracting liquids, turning people into toys, and traveling in time.

These abilities reflect the cruelty and madness of their wielders, who use them for selfish or evil purposes. However, they also have their limitations and drawbacks, which the courage and willpower of the heroes can counter. One Piece is a series that explores the themes of freedom, adventure, and friendship but does not shy away from the darker aspects of its world and characters.
