climax one piece Elbaf Arc has revealed some of the most powerful abilities in this world that creator Eiichiro Oda has created for us to enjoy, including some of the most powerful Devil Fruit types. Over the years, Eiichiro Oda has introduced numerous powerful Devil Fruits, as well as unique Devil Fruit types such as the Mythical Zoan, the Ancient Zoan, and even the Logia and the special Paramecia. The most powerful Devil Fruits that exist in the world of One Piece are unique and do not belong to any category, and are wielded by the kings of the world, Nero or Imu.
Imu possesses the most unique and powerful Devil Fruit in the entire world. one pieceKnown as the Devil's Fruit or 'Devil's Fruit', which trumps all other powers in the world. This Devil Fruit is unique, and over the course of One Piece Chapter 1180 to 1188, Eiichiro Oda has officially been confirmed to be the most powerful Fruit in existence in terms of power.
One Piece Chapters 1179-1188 officially confirmed Akuma no Mi as the biggest ability of the story.
one piece The Demon Mi ability was first confirmed in Chapter 1179 of Shueisha's Weekly Shonen Jump Issue 19, released on April 5, 2026. In this chapter, Nerona Imu is a descendant of Elbaf, and Eiichiro Oda confirms in the introduction box that she wields the ability known as Akuma no Mi, or Devil Fruit. As soon as I saw this ability, it felt like the normal Devil Fruit rules didn't apply. This is because Nero and Imu's Devil Fruit are not in the same category as regular Devil Fruits. All fruits that exist in the world of One Piece have a double naming pattern. This was the same across all categories and subcategories that exist in the world of One Piece, such as Luffy's Hito Hito no Mi, Model: Nika, Enel's Goro Goro no Mi, Katakuri's Mochi Mochi no Mi, Big Mom's Soru Soru no Mi, Sakazuki's Magu Magu no Mi, or other fruits. All Devil Fruits have a dual naming pattern, in addition to Nerona Imu's unique Akuma no Mi ability.

Moreover, all the fruits that exist in the world one piece Although it falls into a unique category called Logia, Zoan, and Paramecia, the fruit of Nero or Imu is a 'devil's fruit'. This means that it stands above all other Devil Fruits and exists in a class of its own. The power of Nero or Imu officially confirms to us that this Devil Fruit is its own kind and a unique force that rules over everything. So far, Eiichiro Oda has revealed quite a few of Nero and Imu's abilities, and needless to say, they are incredibly powerful fruits. Nerona Imu can use abilities that grant various powers to individuals through brands known as Covenants, among other things. As explained in Chapter 1167 of One Piece in WSJ Issue #1, December 1, 2025, there are three different covenants in the world of One Piece. They are the Shallow Covenant, the Abyssal Covenant, and finally the Abyssal Covenant. They all grant the user immense power, with Abyssal being the most powerful, Depths being wielded by Holy Knights, and Shallows being the weakest of them all.
“There are three levels of covenant. The shallow is merely a vestige of solidarity, but the covenant of the deep and the covenant of the abyss are reserved for only 13 exclusive individuals who can enter into a covenant with the True God.” — Five elders explain the covenant. One piece 1167 pieces
Imu also has an ability called Domi Reversi, which was officially confirmed in One Piece Chapter 1150, allowing her to utilize her Devil Fruit powers to turn her enemies into demon slaves. Nero or Imu can create an army of immortal slaves in seconds, but this is only a small portion of their immense Akumanomi abilities.
Imu can also call up a spellbook, which is believed to contain thousands of spells, which allows him to utilize a variety of abilities, including summoning various weapons. The actual size of this spellbook has not yet been confirmed.
Among other things, Nero or Imu possesses the power of Omen or Maki, which manifests itself in the form of black flames that can be manipulated in countless ways in battle. The Fruit of Nero or Imu exhibits the characteristics of all three types of Devil Fruit: Logia, Paramecia, and Zoan, which is why Devil Fruits exist as unique types. For example, Imu's black blob-like form shows the same power as its Logia type. His normal state gives him the ability to utilize demonic transformations and covenants similar to the Zoan type, bestow omens on individuals, manipulate black flames, conjure books, and use spells in battle, all belonging to the Paramecia class. Clearly, Imu's abilities tower over all devil fruits, and it makes sense why they are called 'devil fruits'.
“The Omen is my military power. It is the power that resides within all living things. People crave power. But when they easily obtain the power they crave, it leads to corruption.” — Imu explains Omen. One Piece Episode 1181
Why Nerona Imu's Akuma no Mi Beats Nika Fruit
As it stands, Nerona Imu's Akuma no Mi is clearly much stronger than Luffy's Hito Hito no Mi (model: Nika). The Nika fruit is powerful and allows Luffy to transform into the Sun God of the One Piece universe, but it is by no means a match for Imu's Akuma no Mi abilities. Nika is powerful, especially when his imagination is at its peak, but Akuma no Mi's abilities are more dangerous and varied.
Imu's skill set was officially tested against Nika in One Piece Chapter 1188 in Issue 33 of Shueisha Weekly Shonen Jump on July 12, 2026. It was very clear to us that Nika was rather easily overpowered and easily defeated.

The full power of Nero or Imu has not been revealed yet.
It's important to keep in mind that Imu is strong, but is currently heavily nerfed. Imu was caught vomiting blood as soon as he stepped on Elbaf. one piece April 5, 2026 Episode 1179. During the entire battle with Loki, Imu felt considerable pain as he was on the lower side. Sommers also directly confirmed that Imu's body was not designed to be in the Underworld in One Piece Chapter 1182, released on May 10, 2026, in Issue 24 of Shueisha's Weekly Shonen Jump, meaning that Oda has already given him a significant nerf.
Despite this, he was able to easily defeat Luffy, on top of having already fought Loki. Certainly, Nerona Imu's Akuma no Mi surpasses Hito Hito no Mi, Model: Nika, and every other Devil Fruit that exists in the One Piece universe. The only fruit that can potentially match it is Blackbeard's Yami Yami no Mi, but it's still not even remotely close in terms of firepower. The only way Blackbeard can stand a chance against Imu is to cancel his abilities and strike when he gets the chance. However, due to Imu's diverse abilities, not even Blackbeard stands a chance against him.
