One Piece is frequently misunderstood as a light-hearted series filled with humorous characters, but that misconception couldn't be more wrong. The series delves into numerous serious issues that viewers might encounter in their own lives. Additionally, One Piece features a selection of truly terrifying characters.
Many of these characters possess a cruel nature that is complemented by a frightening appearance. The combination of these elements is sufficient to instill fear in the hearts of the audience, yet certain characters elevate the intensity with their exceptional abilities. Utilizing the darkest powers they possess, they enhance their infamous reputation even more.
7 Soru Soru no Mi
Big Mom, the queen of Totto Land and one of the Four Emperors, possesses the Soru Soru no Mi. Formerly a member of the Rocks Pirates, she later formed her own crew. Unpredictable and dangerous, Big Mom is known to take lives without hesitation, even those of her own children, over trivial matters.
Stopping Big Mom proves to be a formidable task, especially when she is enraged. Utilizing the Soru Soru no Mi, she has the ability to strip individuals of their entire lifespan, instilling immense fear in even her own offspring.
6 Yami Yami no Mi
The Devil Fruit known as the Yami Yami no Mi, or the Dark Dark Fruit, was consumed by Blackbeard after he stole it from Thatch. Blackbeard had eagerly awaited the chance to obtain this Devil Fruit for a lengthy period of time, and it is evident why. This fruit grants him the power to manipulate darkness at his will, making it the most powerful ability in the world of One Piece.
The darkness created by the Yami Yami no Mi possesses a distinct quality, possessing an intense gravitational force that crushes anything within its reach. Additionally, it possesses the ability to neutralize the powers of other Devil Fruits, likely the primary reason why Blackbeard sought after it. Furthermore, Blackbeard is capable of utilizing the Yami Yami no Mi to absorb the attacks launched by his adversaries.
5 Shibo Shibo no Mi
The Shibo Shibo no Mi is a Paramecia-type Devil Fruit consumed by Charlotte Smoothie. It debuted in the Whole Cake Island arc, showcasing Smoothie's ability to draw out juice from living and non-living entities.
This ability is deeply unsettling, as it depletes the moisture within a person's body, leaving them severely dehydrated. When used on a woman, it elicited nothing but screams and desperate pleas for mercy. Undoubtedly, this power is perilous, and fans might anticipate its potential recurrence in the future.
4 Hobi Hobi no Mi
After eating the Hobi Hobi no Mi, Sugar of the Donquixote Pirates no longer aged physically, thanks to its incredible power. This Devil Fruit is truly terrifying, allowing Sugar to transform anyone into a living toy.
Once transformed, the individuals retain their memories but are completely forgotten by those who know them. It is truly frightful to imagine being trapped in a toy's body, with no one even acknowledging your existence.
3 Ice Oni Virus
The Ice Oni virus was originally developed by Queen, who was previously a member of the legendary scientific group MADS, led by Dr. Vegapunk. During his time with MADS, Queen gained extensive knowledge about Lineage Factor and various other subjects. Utilizing this knowledge, he devised new weapons to enhance his arsenal.
Among his most remarkable creations is the Ice Oni virus, a highly contagious virus that spreads rapidly from person to person. Unfortunately, there is no known cure for the virus apart from the consumption of an antidote. Infected individuals experience a sharp increase in their physical abilities, but tragically, they also suffer from a gradual loss of sanity. Eventually, the strain on their bodies becomes too much, resulting in a complete loss of their senses and ultimately leading to death. Unquestionably, this power stands as one of the darkest forces in the series.
2 Kage Kage no Mi
Gecko Moria possesses the formidable Kage Kage no Mi, a Devil Fruit that grants him the ability to pilfer the shadows of individuals. Utilizing this power, Moria assembled an invincible legion of immortal zombies, aiding him in accomplishing his objectives.
Upon successfully snatching someone's shadow, the individual falls into a deep coma lasting for two days. Additionally, they are constrained to dwell within the shadows, for even the slightest contact with sunlight promptly causes their disintegration. Given the nature of this ability, it comes as no surprise that Moria was capable of contending against formidable adversaries like Kaido.
1 Mori Mori no Mi
The Mori Mori no Mi, owned by Admiral Ryokugyu, is a Logia-type Devil Fruit. An exhibit of the fruit's power occurred during the conclusion of the Wano Country arc. With the Mori Mori no Mi, Ryokugyu possesses the capability to generate and manipulate plant life.
Ryokugyu's plant creations display remarkable sturdiness and have the capability to overpower numerous adversaries effortlessly. By infiltrating an opponent's body, the roots of these plants can extract moisture, resulting in complete incapacitation. This unique ability presented by Ryokugyu renders battling against him significantly challenging.
