On August 23, 2026, in Shueisha's Weekly Shonen Jump Issue #39, One Piece saw the release of chapter 1191, which showcased the brand-new Devil Fruit power of the strongest character in the world at the moment, Nerona Imu. Imu is the ruler of the World Government and the wielder of the legendary Akuma no Mi.
In One Piece chapter 1179, which was released officially on April 5, 2026, Imu made landfall in Elbaf and has since done incredibly well to showcase his strength. Now, in One Piece chapter 1191, Imu unleashed his new strongest Devil Fruit power by taking on a unique transformation, which brings out even more of his strength. This new power could potentially be tied directly to the 19 Kings of the One Piece world, and its full extent will be shown to us on September 6, 2026, with the release of chapter 1192.
One Piece Chapter 1191 was significant for Nerona Imu as it once again showed his superiority over all the characters present in Elbaf. Previously, Chapter 1190, which was officially released on August 10, 2026, showed us the battle between Imu and Scopper Gaban. Against all odds, the Left Arm of the Pirate King pushed Imu quite a lot and did more damage to him than the combined effort of Luffy and Loki. Imu's Akuma no Mi form took quite a lot of damage from Gaban's Yachitakeru, which was an incredibly powerful strike infused with Supreme King Haki. After sustaining quite a lot of damage, Nerona Imu decided to go all out and utilized his strongest Devil Fruit transformation in Chapter 1191.
"Crew of the King of the Pirates! I failed to foresee what would become of those mere children at God Valley! I should've eliminated all of it on God Valley, along with Rocks, on that day, years ago!" — Imu shocked upon witnessing Gaban's power, One Piece Chapter #1191
This new power saw him get much bigger in terms of size and take on a completely different appearance as well. Imu's hands and legs were completely coated in Omen, and the ring of black flames with eyes embedded in it, which was previously floating behind his back, was now around his waist and his wrists. Furthermore, Imu also sprouted much bigger wings than before, and his hair took a flame-like appearance similar to Luffy's Gear 4: Snake Man transformation. As things stand, this new form that was officially unveiled to us in Chapter 1191 is the peak of Imu's Devil Fruit powers. It is the ultimate Akuma no Mi form that Oda has revealed to us so far, and it pushes Imu to a completely new level. In fact, Nerona Imu himself stated in Chapter 1191 that his new form is so strong that the next strike from it would be strong enough to end both Luffy and Gaban, who had already sustained quite a lot of damage from him.
It is interesting to note that Nerona Imu's Akuma no Mi powers don't function like traditional Devil Fruit abilities. For one, this fruit is named ‘The Devil’s Fruit’ and does not have a double-naming pattern like all the other fruits that exist in the One Piece world, such as Gomu Gomu no Mi, Hito Hito no Mi, Gura Gura no Mi, Goro Goro no Mi, and every other fruit that exists. At the same time, it is also important to note that this fruit does not have a classification. Eiichiro Oda did not assign any classification to Imu's Akuma no Mi when it first debuted in Chapter 1179 on April 5, 2026, in Shueisha's Weekly Shonen Jump Issue #19. A case could be made for this fruit to fit any of the three categories of Logia, Zoan, and Paramecia, depending on which form Imu is in.
"800 years ago, the 19 Kings who forged this world took an oath of equality, thrusting their weapons into the ground around the Empty Throne. Blade of Chaos, Tohu! Vohu! Nemesis! Longinus! Stigma! Muramasa! They are the 19 weapons of those who brought the world to heel! The Great One used Omen to bring them back and grant them to us.
There are no lies among the legends each family passed down!" — Sommers explains the 19 Kings’ Weapons, One Piece Chapter #1189
