What is Luffy’s Devil Fruit in ‘One Piece?’


Throughout our journey alongside Luffy in One Piece, we’ve had the privilege of witnessing his remarkable evolution from a spirited youngster to a burgeoning pirate. Presently, we’re navigating the adventures of Monkey D. Luffy, the revered captain of the Straw Hats Grand Fleet and the formidable Emperor of the Sea.

Undoubtedly, it’s been an absolute delight to observe Luffy’s authentic essence persisting while his combat skills continually burgeon throughout each successive arc. Yet, none of us could have predicted that the rookie we met at the outset would metamorphose into one of the most feared and respected pirates on the seas. We might have anticipated it vaguely, but it took a staggering 26 years for us to arrive at this point.

Throughout the series, we’ve also borne witness to the evolution of Luffy’s abilities. We’ve seen the unveiling of at least five different gears, his remarkable mastery of Haki, and, of course, his unparalleled genius on the battlefield. If you’re feeling a bit perplexed about the intricate details of his Devil Fruit and its capabilities, fear not — allow me to elaborate.


Luffy’s Devil Fruit, for the longest time — precisely 25 years — was believed to be the Gum-Gum Fruit. However, while that notion isn’t entirely incorrect, it’s also not entirely accurate. In actuality, Luffy’s Devil Fruit is the Human-Human Fruit, Model: Nika. This revelation occurs during the clash between Kaido and Luffy in Wano, as Luffy’s fruit undergoes an awakening, completely altering his appearance.

This particular Devil Fruit belongs to the lineage of the Human-Human Fruit, akin to Chopper’s. It’s classified as a Mythical Zoan-type fruit, transforming its user into the mythical warrior known as “Sun God Nika.” It renders Luffy’s entire body white — hair, attire, everything — and essentially, the only limitation to his power lies within his creativity, making it practically boundless.

Essentially, he gains the ability to turn everything around him, including his adversaries, into rubber, all while embodying the legendary figure. For years, the existence of this fruit remained concealed, renamed by the World Government as the “Gum-Gum fruit” in an attempt to suppress its existence. Only Imu and the five elders are known to be cognizant of this fruit, to the extent that Saturn immediately recognizes Nika upon seeing Luffy.

The gears in One Piece denote techniques devised by Luffy to augment his physical prowess in combat, leveraging the rubber properties of his Devil Fruit. Gear 2 and Gear 3 were introduced in Enies Lobby as alternative states to his regular form. Gear 4 made its debut in Dressrosa, and the revelation of Gear 5 occurred during the events in Wano.

Naturally, each of these gears exacts a toll on his body. Gear 2 initially shortened Luffy’s lifespan due to the strain on his body and organs, but that has ceased since. Similarly, Gear 4 temporarily limited Luffy’s abilities after usage, leaving him unable to utilize Haki or the Gear for a period. Gear 5 appears to be the most exhausting of all, causing Luffy to experience temporary aging upon activation.

Gear 2, as mentioned earlier, accelerates the flow of Luffy’s blood within his vessels and organs, thanks to their rubbery properties, significantly enhancing his capabilities and speed. Even to this day, Luffy frequently employs Gear 2, especially when executing his Red Hawk attack.

In contrast, Gear 3 involves Luffy blowing an enormous amount of air into his thumb, inflating the bones of that specific body part. This inflated form allows him to inflict massive damage on a grand scale, whether against adversaries or even structures. Presently, we’ve observed Gear 3 being utilized alongside Haki in Wano.

Gear 4 introduces a more intricate set of abilities. Developed during his training with Rayleigh, Luffy activates Gear 4 by inflating his arm. This action results in three distinct forms: Boundman, resembling a bouncing rubber ball; Tankman, which increases Luffy’s size and enables him to deflect attacks using his body; and Snakeman, a slimmer form focused on speed and offense.

Gear 5, on the other hand, represents the awakening of the Human-Human Model: Nika Devil Fruit. Unveiled during the Raid on Onigashima in the clash against Kaido, this fruit had remained dormant since the void century. Consequently, Luffy gains the ability to manipulate his surroundings into rubber at will, altering his body’s shape and size and bestowing upon him god-like strength and speed.

This awakening is described as possessing “the most absurd power in the world,” granting its wielder the freedom to engage in combat as they see fit, even able to convert thunder and lightning from the sky into rubber. He becomes a “Warrior of Liberation,” spreading joy and freedom to those around him. Moreover, Luffy seems capable of sustaining Gear 5 as long as he matches his heartbeat to the rhythm of the Drums of Liberation. Undoubtedly, this stands as Luffy’s most formidable Gear and form in the ongoing story.

As of now, we’re left in suspense regarding how Luffy’s abilities might evolve further. It’s a waiting game to see if Eiichiro Oda will surprise us once more with Luffy’s newfound powers. In the interim, these represent the diverse array of Gears that have emerged thus far in Luffy’s journey.
