Gomu Gomu no Mi/Techniques

Monkey D. Luffy always begins his attacks by saying "Gomu Gomu no..." and finishes with an attack-specific word, either in Japanese or English, such as Gatling or Yari. The majority of them are named after guns and various other firearms. This naming pattern originates from the claim that Luffy made to Shanks that his fist is as strong as pistol fire. Other known attacks were named after various other aspects such as physical objects to mental stupidity.

It is important to note that this is not a martial art. Luffy is a brawler and merely uses his favorite techniques on the spot sporadically and experiments with new moves in between arcs and during the two years spent training on Rusukaina with Rayleigh.

In the VIZ manga, all of Luffy's Devil Fruit based attacks begin with "Gum-Gum" instead of "Gomu Gomu". In the 4Kids dub, Luffy's attacks also begin with "Gum-Gum". However, the gun references are completely renamed for censorship reasons. In the Funimation dub, they begin with "Gum-Gum" and the gun references are kept in. The Odex dub often translated Gomu making attacks begin with "Rubber" for the first 56 episodes and "Rubber Rubber" for 57 and up.

Oars was also able to utilize some of these techniques while under the effect of Moria's Kage Kakumei technique.

Gun and Artillery Themed Attacks
The known normal Devil Fruit based attacks so far that are named after guns and various other artillery, that Luffy has used, are as follows:


 * Gomu Gomu no Pistol (ゴムゴムの): Luffy's signature attack; he stretches his arm back then throws a devastating punch. In other words, it is a standard straight punch, augmented with stretching. This attack can be used from short to long range. Luffy would typically increase the striking reach of fist by 'charging up' by means of first repeatedly swinging his un-stretched punching arm around before using the spinning force to both stretch his arm to its limits, and to maximize the hitting power. Its name comes from Luffy's claim to Shanks that his punching arm is "as powerful as a pistol!" The first version of this is seen when Luffy tried fighting against Ace and Sabo when he was a child, but it kept failing. Ace asks for the point of his fruit, and Luffy replays the move in his head, saying it does not come out the way he wants. This was first successfully seen being used on the Lord of the Coast after ten years of training in the manga, while in the anime, it is first seen being used against Alvida. This is called Gum-Gum Pistol in the VIZ manga and Funimation dub, Gum-Gum Blast in the 4Kids dub, Rubber Pistol in Episodes 1-53 of the Odex dub, and Rubber Rubber Pistol in the Odex dub after Episode 53. In the second version of Romance Dawn, Luffy used a technique similar in concept to this attack against Spiel. According to a fan poll, this is the ninth favorite attack amongst fans with a total of 552 votes.




 * Gomu Gomu no Pistol "Shot" (ゴムゴムの｢｣ or ｢｣): Starts off as an ordinary Pistol attack, after which Luffy "twangs" his stretched arm, causing his fist to connect multiple times. This was first seen being used against Crocodile after Luffy wet his own body with water. In the anime this is called Gomu Gomu no Pistol and Shot (or merely called Gomu Gomu no Shot/Shotgun and by proxy written as "ゴムゴムの散弾"). In the VIZ manga, this is called Gum-Gum Pistol Shotgun, while in the 4Kids dub, it is called Gum-Gum Quake. Coincidentally, the kanji 弾 not only means bullet, but can also mean to "fling", "twang" or "repel/deflect" in this move's case.


 * Gomu Gomu no Rocket (ゴムゴムのロケット): Luffy's main method of traveling long distances fast. He stretches out one or both of his arms, grabs a handhold, and then retracts them, projecting himself high into the air at high speeds, over great distances, or even into an opponent. This technique is often times reckless especially if not done properly as Luffy could accidentally propel himself into a body of water or worse. Indeed, Luffy has little to no control after launching himself, being unable to change directions in mid-flight, and is only able to (barely) decelerate before landing. This was first seen being used to propel Luffy to the top of the Marine Base in Shells Town in the manga. In the anime, it was first seen being used to crash into Alvida's crew. This was first developed when Luffy was a child, along with Ace and Sabo, battling against the king of Mt. Colubo, a giant tiger; Ace gave this attack its name. This technique is also capable of landing devastating attacks against larger opponents as shown against Dorry. A humorous usage of this "attack" was accidentally against Ace and Smoker in a restaurant, who are both Logia users but did not have the reflex to counter the charge. This is called Gum-Gum Rocket in the VIZ manga and the 4Kids and Funimation dubs. However, in the anime, sometimes when this technique is used, Luffy dubs it with a different title, like Gum-Gum Pardon the Intrusion, or Gum-Gum Mooring Line.
 * So far only in Jump Ultimate Stars as his jumping strong attack, this attack has been used without Luffy grabbing onto anything as a mere simple diving attack (same applies to his JET Rocket in Gear Second).




 * Gomu Gomu no Bazooka (ゴムゴムのバズーカ): Luffy stretches both his arms far back, and then hurls them forward, striking his opponent with both instantaneously with a double open palm strike with both hands, that frequently sends the recipient(s) flying off the other direction. This is usually used as a finishing move, he often prefers to do it at point-blank range, sometimes running up to his opponent as he's charging it. This was first seen being used to defeat Buggy. This is called Gum-Gum Bazooka in the VIZ manga and Funimation dub, Gum-Gum Double Barrel in the 4Kids dub, and Rubber Rubber Bazooka in the Odex dub. According to a fan poll, this is the fifth favorite attack amongst fans with a total of 995 votes. This is one of the few gun-based attacks (not named after any ammunition) to not be written in kanji. In the video games, the Gomu Gomu no Cannon followed after a Gomu Gomu no Gatling is somehow often done akin to this move.
 * Gomu Gomu Gomu Gomu no Bazooka (ゴムゴムゴムゴムのバズーカ): A stronger version of Gomu Gomu no Bazooka, used to send flying heavy opponents. The attack is the same as Bazooka but with the difference that when Luffy stretches his arms back, he stretches them an extremely long distance. The distance of the stretched arms back is so long that it can cover from the Drum Castle to the villages of Drum Island. After the strike unlike regular Bazooka, Luffy's arms end up crossed and the impact is such that he recoils a little. It was first used to defeat Wapol by sending him flying out of the Drum Kingdom. While not named in most cases differently from his normal version Gomu Gomu no Bazooka, it has been first given this name as his Special Attack A in Jump Super Stars for his 5 koma version (where it can be charged up to make Luffy say "Gomu" a total of 6 times during the charging period).
 * Gomu Gomu no Gatling (ゴムゴムの): Luffy uses his stretching ability to bring his fists forward repeatedly in a blurry, rapid barrage of strong punches that creates the illusion of him having multiple arms, however he does not actually grow more arms so he can still be stopped by an opponent fast enough (as Enel, Rob Lucci and Usopp have demonstrated). This was first seen being used against a group of Black Cat Pirates after being accidentally hypnotized stronger by Jango. This is called Gum-Gum Gatling Gun in the VIZ manga, Gum-Gum Gatling in the Funimation dub (and sometimes the VIZ manga), Gum-Gum Rapid Fire in the 4Kids dub, Rubber Gatling in Episodes 1-53 of the Odex dub, Rubber Rubber Punch during one scene in the Warship Island arc in the Odex dub, and Rubber Rubber Gatling for the rest of the Odex dub. According to a fan poll, this is the favorite attack amongst fans with a total of 3785 votes.
 * In several of the video games, it is common to see Luffy finish off this move with an extra stretching strike, though it varies per game:
 * In the Grand Battle series, he finishes with a simple stretch punch akin to Gomu Gomu no Pistol.
 * In Battle Stadium D.O.N, he finishes with a Gomu Gomu no Bullet which can be fully charged, and also does so for his Gomu Rush in Jump Super Stars and Jump Ultimate Stars (the very former game of the three oddly has his arm fully stretched for the Gomu Gomu no Bullet portion).
 * While in games such as the Pirate Warriors games and J-Stars Victory Vs, he performs a Gomu Gomu no Cannon that's more akin to a standard Gomu Gomu no Gatling-into-Gomu Gomu no Bazooka instead.
 * In some other media however, such as in Jump Super Stars and Jump Ultimate Stars, the kanji for the "Gatling" portion of the move's name is instead written as 銃乱射 (jūransha), making the attack literally mean "Rubber Rubber Gun Wild Shot". Ransha, being a part of the idiom ransharangeki (乱射乱撃) are both Japanese words for indiscriminate and random shooting.


 * Gomu Gomu no Bullet (ゴムゴムの): Luffy stretches one arm, far behind him while running, then snaps it back to deliver a short-distance, one-fisted powerful blow to an opponent. This was first seen being used on Don Krieg. This is called Gum-Gum Bullet in the VIZ manga and Funimation dub and Gum-Gum Burst in the 4Kids dub. According to a fan poll, this is the twenty eighth favorite attack amongst fans with a total of 68 votes. In all instances in the anime before the Water 7 arc, this attack is always called "Gomu Gomu no Pistol". Despite this move's name, this attack's range is meant to be for close quarters compared to the likes of Pistol and/or its other timeskip variant. Other media may instead have Luffy instead throw a hooking punch akin to Gomu Gomu no Kama (the most common type of punch Luffy uses for this is often a straight blow).
 * Oddly enough, in Battle Stadium D.O.N., this attack used as the finishing followup from both the Gomu Gomu no Pistol and Gomu Gomu no Gatling, where he punches with a fully stretched arm as opposed to a non-stretched one.


 * Gomu Gomu no Bow Gun (ゴムゴムのボーガン): Taking hold of his opponent from behind, Luffy repeatedly twists his torso vertically around his hips before grasping them with his feet and then rapidly untwisting, creating a snapback that sends his opponent flying upwards. This was first seen being used against Wapol. This is called Gum-Gum Bowgun in the VIZ manga and Funimation dub and Gum-Gum Crossbow in the 4Kids dub. This is one of the few gun-based attacks (not named after any ammunition) to not be written in kanji.




 * Gomu Gomu no Rifle (ゴムゴムの): Similar to the Gomu Gomu no Bullet, but Luffy twists his arm around as he stretches it behind him and hits the opponent at close range, massively increasing the velocity of the punch as twisting the arm stretches the arm even further without having to draw it back any longer which also saves the amount of time the kick-back takes. This attack is called Gum-Gum Rifle in the VIZ manga and Funimation dub and Gum-Gum Drill in Grand Adventure. This was first seen being used against Enel. According to a fan poll, this is the twenty first favorite amongst fans with a total of 85 votes. The kanji of this attack likely references the spin on a bullet fired from most rifles that give it more piercing power and torque than smaller firearms.
 * So far, only the Pirate Warriors series gives this move and one other variant the ability to fire a powerful compressed projectile of force from the punch that gives it fairly long range, akin to Gomu Gomu no Cannon (and funny enough, akin to an actual rifle shot).


 * Gomu Gomu no Cannon (ゴムゴムの): Luffy builds up speed and momentum with a long series of quick punches similar to Gomu Gomu no Gatling, stopping just short of the target(s) at first, and finishes with a single double-palm blow similar to Bazooka to thrust-forward the gathered force all at once as a forward projectile. A powerful technique that can pierce strong armor, and, in combination with Roronoa Zoro's Three Sword Style, is devastating enough to puncture a hole through a massive tidal wave. This was first seen being used against one of the Franky Family's Kairiki Destroyers. In the VIZ manga, Funimation dub, and video game Grand Adventure, this is called Gum-Gum Cannon.
 * In several later video games such as in the Pirate Warriors series (only for his pre-timeskip versions) and J-Stars Victory Vs., Luffy instead performs this attack in the style of a basic Gomu Gomu no Gatling-into-Gomu Gomu no Bazooka combo, without the aforementioned projectile blast in both of these cases (though in the latter game, the normal non-Gear versions of Gomu Gomu no Cannon cannot be accessed in his moveset as he always follows up into JET Cannon).
 * Oddly enough, only in the Pirate Warriors series, Luffy is able to unleash this same kind of force with his Gomu Gomu no Rifle and its other variants. Pirate Warriors 3 is also the only game of these cases somehow to allow Luffy only in his PTS form to use the original long-ranged version of Cannon as his Kizuna Special Attack.

Other Weapons Themed Attacks
The known normal Devil Fruit based attacks so far that are named after other weapons other than guns, that Luffy has used, are as follows:




 * Gomu Gomu no Muchi (ゴムゴムの鞭): Luffy stretches his leg and kicks in a wide circle, striking multiple foes. This was first seen being used against a group of Marines in Shells Town. This is called Gum-Gum Whip in the VIZ manga as well as the 4Kids and Funimation dubs.


 * Gomu Gomu no Tsuchi (ゴムゴムの槌): Luffy stretches out his arms while twisting them, and then takes hold of his opponent. He then untwists them, rapidly spinning his opponent, while bringing him crashing to the floor. This was first seen being used against Richie after he and Mohji destroyed Chouchou's master's store. This is called Gum-Gum Gavel in the VIZ manga and Gum-Gum Hammer in the 4Kids and Funimation dubs.


 * Gomu Gomu no Kama (ゴムゴムの鎌): Luffy grabs an object behind his opponent and pulls himself towards them. He then stretches out his other arm and clotheslines his opponent. This was first seen being used against Buggy. This is called Gum-Gum Sickle in the VIZ manga and Funimation dub, and Gum-Gum Fist in the 4Kids dub.


 * Gomu Gomu no Yari (ゴムゴムの槍): Luffy holds his feet together (with the bottoms of each touching each other) and kicks with both simultaneously via his toes (giving off the image of an actual spearhead). This was first seen being used against Kuro after Luffy dodged his attack. This is called Gum-Gum Spear in the VIZ manga and the 4Kids and Funimation dubs. There are instances where this attack is also sometimes performed via his two feet stomping on his target's face, making it akin to a two-legged Gomu Gomu no Stamp.


 * Gomu Gomu no Ogama (ゴムゴムの大鎌): Identical to Gomu Gomu no Kama, but he uses both arms for the rocket and the clothesline. This was first seen being used on a group of Krieg Pirates that were attacking the Baratie. This is called Gum-Gum Giant Scythe in the VIZ manga and the 4Kids and Funimation dubs.


 * Gomu Gomu no Ono (ゴムゴムの戦斧): Luffy stretches one leg high into the air, then brings it crashing down via a high-gravity stomp on an opponent or structure, for massive damage, strong enough to destroy large buildings and ships in a single hit. Usually when Luffy executes this attack, after stretching out his leg, he brings his foot down immediately below him, however sometimes (mainly in the anime and in the video games) he keeps his leg extended and brings it down, like a vertical version of Gomu Gomu no Muchi. This was first seen being used on the fins of the Baratie. It was also used to destroy Crescent Moon Galley's ship in the First Romance Dawn although not named. He also defeats Arlong with this move. This is called Gum-Gum Battle Axe in the VIZ manga and Funimation dub and Gum-Gum Axe in the 4Kids dub (and occasionally in the Funimation dub).
 * Despite the kanji for this move being possibly read as "senpu", it is read in Japanese with the kun'yomi rendering for the axe (斧) character instead, unlike all other variations of this attack.




 * Gomu Gomu no Ozuchi (ゴムゴムの大槌): Similar to Gomu Gomu no Mallet, but he performs it using the feet and legs instead of hands and arms while in mid-air. He performed this while he was trapped inside Krieg's net, sending the latter crashing into Baratie's fins. This was first used to defeat Don Krieg. This is called Gum-Gum Giant Gavel in the VIZ manga and Funimation subs, and Gum-Gum Giant Hammer in the 4Kids and Funimation dubs.

Other Concepts and Themed Attacks
The known normal Devil Fruit based attacks so far that are named after other concepts other than weapons, that Luffy has used, are as follows:




 * Gomu Gomu no Fusen (ゴムゴムの風船): A technique where Luffy inflates himself rapidly through his mouth, further increasing his resistance to blunt attacks. With his inflated body, Luffy is capable of deflecting projectile attacks back at his attackers. This is not necessarily always an attack as Luffy can also use this technique for other purposes aside from deflecting projectiles such as escaping Smoker's Smoke Snake technique or using himself as a cushion when his ship is in for a hard landing. This can also prevent Luffy from sinking under water, making him bounce off the surface. This was first seen being used against one of Buggy's cannonballs after Luffy insulted Buggy. This is called Gum-Gum Balloon in the VIZ manga and the 4Kids and Funimation dubs. According to a fan poll, this is the seventeenth favorite attack amongst fans with a total of 162 votes.




 * Gomu Gomu no Kane (ゴムゴムの鐘): While latched onto an enemy, Luffy stretches his neck backwards, then snaps it back for a devastating head butt to the opponent's face (though there exist times where Luffy does not need to latch onto an enemy and only does the headbutt portion). This was first seen being used to defeat Kuro. This is called Gum-Gum Bell in the VIZ manga and the 4Kids and Funimation dubs.


 * Gomu Gomu no Kazaguruma (ゴムゴムの風車): A technique that was used once in the Arlong Arc. Luffy planted his feet into the ground to steady himself, then twisted his body around tightly. He then grabbed hold of Arlong's pet Momoo and unwound, spinning the Sea King around rapidly to crush the Fish-Men surrounding him. After spinning around several times, Luffy then let go of Momoo and threw him far away. While it took out most of Arlong's Fish-Men, it however had the disadvantage of getting Luffy's feet stuck in the ground. This was first used against the Arlong Pirates. This rather reckless move was inspired by the sight of the pinwheel on top of Genzo's hat by Luffy. "Kazaguruma" can be translated as either "windmill" or "pinwheel". In the VIZ manga, this is called Gum-Gum Windmill while in the 4Kids and Funimation dubs, this is called Gum-Gum Pinwheel. Luffy also used an alternate version of this move in the video game Grand Battle! and Grand Battle Rush! where he merely twists his mid-section as he unwinds with both arms out to smack around himself 360 degrees; another version is also during his fight with Rob Lucci, where he simply grabs his target and twisting his mid-section before unwinding, and throwing his opponent. Both these alternate versions do not involve planting his feet on the ground prior.


 * Gomu Gomu no Tate (ゴムゴムの盾): Luffy grabs the fingers of one hand with the other, and stretches them before his face to block blades that pass between the fingers. This was first seen being used on Arlong. This is called Gum-Gum Shield in the VIZ manga and the 4Kids and Funimation dubs. In several video games, this is often his blocking/guarding animation before the timeskip, though it's only in Battle Stadium D.O.N. this is a standalone technique working as a counter/reversal special.




 * Gomu Gomu no Ami (ゴムゴムの網): Luffy entwines his fingers making a net like shape and then stretches out his fingers making a larger net in an attempt to trap his opponents. This was first seen being used on Arlong. This is called Gum-Gum Finger Net in the VIZ manga and the 4Kids and Funimation dubs.


 * Gomu Gomu no Ikebana (ゴムゴムの生け花): A technique in which Luffy grabs hold of the Going Merry's mast and slams it into his opponent. This was first seen being used on Laboon. The name is derived from the fact that the way the mast is slammed resembles typical Japanese flower arrangements. In the 4Kids dub, this technique is not present. This is called Gum-Gum Bouquet in the VIZ manga and Gum-Gum Flower Arrangement in the Funimation dub.




 * Gomu Gomu no Stamp (ゴムゴムのスタンプ): Luffy stretches his leg out and hits his opponent with the bottom of his foot, leaving an imprint, or "stamp", of his sandal. This was first seen being used to defeat Mr. 3. In the VIZ manga and Funimation dub this is called Gum-Gum Stamp, and in the Odex dub this is called Rubber Rubber Stamp. Sometimes in a few instances, the aforementioned Gomu Gomu no Yari is performed akin to a Gomu Gomu no Stamp, only with both of Luffy's feet close together.
 * Gomu Gomu no Stamp Gatling (ゴムゴムのスタンプ): Similar to Gomu Gomu no Stamp, except he makes multiple strikes with his feet. This was first seen used at Marineford against the Three Admirals, crushing a mast frozen by Aokiji. In the VIZ manga, Funimation adaptations, this is called Gum-Gum Stamp Gatling.


 * Gomu Gomu no Dame Da! (ゴムゴムのダメだ): A joke technique in which Luffy stretches his arm to stop Usopp stealing his water given to him by Toto. This was first used against Usopp. This is called Gum-Gum No Way! in the VIZ manga and 4kids and Funimation dubs. It was additionally called Gum-Gum Keep Away! in the 4Kids dub and Gum-Gum Leave me Alone! in the Funimation dub. In the anime, it was used again in the Rainbow Mist filler arc. According to a fan poll, this is the twenty fourth favorite attack amongst fans with a total of 76 votes.




 * Gomu Gomu no Baku Baku (ゴムゴムのバクバク): Luffy stretches his mouth wide open, and attempts to bite or swallow his opponent. This attack was named after and copied from Wapol's Baku Baku no Mi powers. In the VIZ manga and the 4Kids and Funimation dubs, this is called Gum-Gum Munch-Munch. This technique was first seen being used against Crocodile.


 * Gomu Gomu no Marunoko (ゴムゴムの丸鋸): Luffy grabs his opponent from afar with both arms and winds himself up like with a bow gun. He then kicks off from the ground and spins towards his opponent to deliver a powerful head butt. This was first seen being used against Crocodile after Luffy wet his own body with water. In the VIZ manga and the 4Kids and Funimation dubs, this is called Gum-Gum Buzzsaw.




 * Gomu Gomu no Storm (ゴムゴムの): An extremely powerful move and one of Luffy's strongest attacks. Luffy first uses Gomu Gomu no Balloon and twists his body around tightly, then blows the air out behind him while untwisting to fly in forward while spinning towards an opponent, where he delivers a constant barrage of powerful punches similar to Gomu Gomu no Gatling, with power greatly enhanced by the momentum of his spinning launch. This was first seen being used to defeat Crocodile. This attack was powerful enough to beat Crocodile through an extremely thick ceiling of solid bedrock and cause a huge earthquake in Arabasta, and then propel him several hundred feet into the air. This technique can be used going horizontally forward, upwards towards airborne targets, and downwards while Luffy is airborne. In the VIZ manga and the 4Kids and Funimation dubs, this is called Gum-Gum Storm. According to a fan poll, this is the seventh favorite attack amongst fans with a total of 815 votes. In the video game One Piece: Unlimited Adventure, an alternate version of this move is seen where Luffy first twists himself right before inflating, making the move quicker and faster.


 * Gomu Gomu no Hanabi (ゴムゴムの花火): Luffy jumps into the air and spins around rapidly. He then stretches and wraps himself in his own arms and legs like a rubber ball. When the rubber rebounds and the 'ball' is unwrapped he unleashes a flurry of punches and kicks of increased speed, that go in every direction due to his fists and feet bouncing back and forth. This was first seen being used against the White Berets in Skypiea. In the VIZ manga, the English version of Pirates Carnival (dubbed by 4Kids), and the Funimation dub, this is called Gum-Gum Fireworks.




 * Gomu Gomu no Boh... (ゴムゴムのボー): A technique in which Luffy "switches off" his conscious mind, allowing him to avoid attacks entirely on instinct. This made him immune to Enel's mind-reading Mantra ability. The disadvantage is that he can neither think nor attack in this state. This was first used against Enel. According to a fan poll, this is the twentieth most favorite attack amongst fans with a total of 95 votes. This is called Gum-Gum Space-Out in the VIZ manga, Gum-Gum Daze... in the Funimation dub, and Gum-Gum Airhead in the Funimation subs.


 * Gomu Gomu no Tako (ゴムゴムのたこ): A technique in which Luffy makes his appendages go limp that they resemble the tentacles of an octopus. In the anime, he takes a deep breath which inflates his head to a large size and his limbs go limp when he exhales. This was done in an attempt to figure a way to fight against Enel's Mantra ability. This is called Gum-Gum Octopus in the VIZ manga and Funimation dub.
 * Gomu Gomu no Tako Hanabi (ゴムゴムのたこ花火): Much like Gomu Gomu no Hanabi except, due to the previous move, Gomu Gomu no Tako, his limbs bounce off of walls without losing speed. Because his limbs are limp, Luffy cannot predict or control where they will go if they ricochet off of an object, much less the unlucky opponent(s). This is completely advantageous against a Kenbunshoku Haki user as they also cannot predict where Luffy's punches and kicks would come at them. This technique was used against Enel during Luffy's battle against him. In the VIZ manga and the Funimation dub, this is called Gum-Gum Octopus Fireworks.




 * Gomu Gomu no Mikata Robo (ゴムゴムの味方ロボ): Luffy wraps his arms and legs around a person's limbs in order to manipulate their movements. This was first used against a Marine in Enies Lobby. In the VIZ manga and Funimation dub, this is called Gum-Gum Ally Robot.
 * Mikata Robo Punch (味方ロボパンチ): Luffy uses his "Ally Robot" to punch an opponent. This was first used against a Marine in Enies Lobby. In the VIZ manga and Funimation dub, this is called Ally Robot Punch.
 * Mikata Robo Kick (味方ロボキック): Luffy uses his "Ally Robot" to kick an opponent. This was first used against a Marine in Enies Lobby. In the VIZ manga and Funimation dub, this is called Ally Robot Kick.


 * Gomu Gomu no Kazan (ゴムゴムの火山): Similar to Gomu Gomu no Ono, except Luffy's foot is stretched upwards to break through a roof, and is not followed by a stomp like Gomu Gomu no Ono. This was first seen being used against marines at Enies Lobby. In the VIZ manga and Funimation dub, this is called Gum-Gum Volcano. In some instances, such as a few video games, it is often the starting technique for the upward version of Gomu Gomu no Storm.


 * Gomu Gomu no Haragi (ゴムゴムのハラギ): Luffy inflates himself and draws a face on his expanded belly and moves it while he dances. In the manga, this move was not named. This joke technique was used in the Kuja banquet on Amazon Lily. In the Funimation adaptations, this technique is called Gum-Gum Belly Talk. It was possibly inspired by Pagaya, who performed a similar dance during the end-of-hostilities party on Skypiea.


 * Gomu Gomu no Ame (ゴムゴムの雨): Luffy jumps into the air and performs a strong, rapid-fire punching attack while spinning. Similar to Gomu Gomu no Storm, except without inflating himself beforehand, and he punches while descending like rain. It was first seen being used on jailers of Impel Down. In the VIZ manga and Funimation adaptations, this is called Gum-Gum Rain. This technique was actually first mentioned by a fan in an earlier SBS, with the key differences of rather than jumping, he propels himself using the same method as Gomu Gomu no Storm, and rather than punching the enemy, Luffy spits at them. In the Pirate Warriors games, it functions more akin to an airborne version of Gomu Gomu no Gatling aimed downward with no spinning involved unlike Storm (and funny enough, the Gatling itself is also an airborne-based attack in the said games).




 * Gomu Gomu no Migawari (ゴムゴムの身代り): Luffy avoids getting hurt from his opponent by grabbing someone else around him and use them as a human shield, normally against their will akin to Mikata no Robo. This was first seen used against Dracule Mihawk's Yoru, with Buggy as the shield. Buggy is not harmed due to his Devil Fruit ability, but it does not make him any happier about it. The Gear 2 version of this attack was first seen before this normal version made its debut. In the VIZ manga and Funimation adaptations, this is called Gum-Gum Human Shield.

Anime Only Techniques
In the anime, Luffy displays some more unique uses of his rubbery body. The known named regular Devil Fruit techniques that are exclusive to the anime are as follows:


 * Gomu Gomu no Pachinko (ゴムゴムのパチンコ): Luffy grabs hand and foot holds, then intercepts a projectile, stretching back and firing the projectile back at its origin. In the Warship Island Arc he used this move to stop a lot of Marines and throw them into the water. This was first seen being used against the cannonball that Fullbody fired at Luffy; whereas in the manga, Luffy bounced it back with a Gomu Gomu no Fusen. This is called Gum-Gum Slingshot in the 4Kids and Funimation dubs, and Rubber Rubber Slingshot in the Odex dub. In the Funimation dub of the Warship Island arc, it is called Gum-Gum Pinball.


 * Gomu Gomu no Neji (ゴムゴムのネジ): Luffy grabs onto a large, spinning object that is shot at him while holding onto a foothold, twists his arms and legs as if to do a Gomu Gomu no Giant Gavel while the force of the object propels him further to his ability's limit, then slams the object into a foe while spinning. This was first seen being used against Bear King in the second One Piece movie.


 * Gomu Gomu no Amidori (ゴムゴムの網取): A technique wherein Luffy stretches his arm out to catch something. This was first seen being used to catch what Luffy assumed to be fish. Instead of catching fish however, Luffy caught an unconscious Apis adrift on her boat. The recoil of this technique is somewhat reckless as Luffy's arm knocked Zoro right off the Going Merry as Luffy reeled it back in. In the Funimation dub, this is called Gum-Gum Grab, and in the Odex dub this is called Rubber Catch.


 * Gomu Gomu no Tsuribashi (ゴムゴムの吊橋): A technique wherein Luffy turns himself into a make-shift bridge by laying his rubber body across a gap. This was first seen being used to help Nami get across a wide gap in Warship Island. In the Funimation dub, this technique is called Gum-Gum Suspension Bridge, and in the Odex dub this is called Rubber Bridge.


 * Gomu Gomu no Nagenawa (ゴムゴムの投げ縄): A technique wherein Luffy entwines himself around something, and then stretches his arm to grab an object. This was first seen being used when the Going Merry was going through a typhoon to get to the Lost Island. Luffy entwined his body to the ship's mast and stretched out his arm to lasso Ryu's raft. In the Funimation dub, this is called Gum-Gum Lasso.


 * Gomu Gomu no Propeller (ゴムゴムのプロペラ): Used against a giant sea bird in the anime, Luffy jumps into the air and does a Gomu Gomu no Gavel, with his hands grabbing the bird's beak to prevent it from attacking him, spinning the bird around in a cyclone before slamming down onto Going Merry's deck. In the 4Kids dub, this is called Gum-Gum Twister and in the Funimation dub, it is called Gum-Gum Propeller.
 * Propeller Modoshi (プロペラ戻し): A continuation of the above technique, after spinning his opponent in one direction, he then spins them in the opposite direction, further disorienting them. It was first used against the giant Lily Enstomach.


 * Gomu Gomu no Mizu Kure (ゴムゴムの水くれ): Similar to Gomu Gomu no Rocket, except Luffy wraps the outstretched arm several times around the target before rocketing towards it. This was first seen being used to get onto Barbarossa's ship in one of the Arabasta anime filler episodes. In the Funimation dub, this is called Gum-Gum Give Me Water.


 * Gomu Gomu no Sadowari (ゴムゴムの砂土割り): While fighting on sandy terrain, Luffy outstretches his arm and skims the surface of the sand to uppercut the opponent from afar. This was first seen being used against Zoro in an Arabasta filler episode because Luffy went delusional from drinking cactus juice and thought that Zoro was Crocodile. In the Funimation dub, this is called Gum-Gum Submarine.


 * Gomu Gomu no Zenmai (ゴムゴムのゼンマイ): Similar to Gomu Gomu no Rocket, however he wraps his arm around a round object multiple times, making it very firm, he then spins around the object then suddenly getting shot very far and high in the direction Luffy wants. This was first been seen trying to get out of the ruins that Zoro and Chopper fell down and Luffy who climbed down. In the Funimation dub, this is called Gum-Gum Spring.


 * Gomu Gomu no Shoot (ゴムゴムのシュート): Used in Pirate Soccer King featurette. Luffy stretches back leg and kicks.


 * Gomu Gomu no Tomotsuna (ゴムゴムの艫綱): Luffy used this to make a way from his ship to another ship. He stretches his arm far to catch the Marine ship and retracts it, just like Gomu Gomu no Rocket. This was first seen being used when he carried Sanji and Taijiyo back to and from a Marine ship in Post-Arabasta arc. In the Funimation dub, this is called Gum-Gum Mooring Line.


 * Gomu Gomu no Bungee (ゴムゴムのバンジー): When holding onto a ledge while stretched, Luffy retracts his arm to pull him up while hopping along the wall. This was first seen being used in Nami's filler episode in the Post-Arabasta arc to get back onto the Going Merry after Luffy accidentally fell off. In the Funimation dub, this is called Gum-Gum Bungee Jump.


 * Gomu Gomu no Warp (ゴムゴムのワープ): A sort of joke move used in the Rainbow Mist. Since the phenomenon creates a wormhole-like effect, Luffy attempts to "rocket" out of it only to end up exactly where he started. In the Funimation dub, this is just simply called Gum-Gum Rocket.


 * Gomu Gomu no Home Run (ゴムゴムのホームラン): Used in Pirate Baseball King featurette. Luffy first hits a baseball with his fist. Next, he twists his body around with Gomu Gomu no Pinwheel. Luffy finally unwinds his body making the ball fly out of his fist and making a home run.


 * Gomu Gomu no Yo-Yo (ゴムゴムのヨーヨー): With a gold ball attached to his arm, Luffy holds onto an object and uses the ball to stretch himself so far that when he snaps back, he is sent flying into the sky. A variation of this is used with Gomu Gomu no Fusen during the Enies Lobby saga as Luffy uses it to escape the Marines by jumping down from a building while still holding on and then bouncing back up. This is known as Gum-Gum Yo-Yo in the Funimation dub.


 * Gomu Gomu no Koma (ゴムゴムの独楽): Luffy wraps an outstretched arm several times around a target, and then pulls his arm away suddenly, causing the target to spin out of control. This was first seen being used against Foxy's Gorilla Puncher #13 in an anime filler episode.


 * Gomu Gomu no Jutte (ゴムゴムの十手): While wielding a jutte, Luffy uses Gomu Gomu no Gatling. Used in the fourth one-hour special, against the Buggy family and later Hatchan. This is also a pun that can mean "ten-hands" as well as referring the weapon used. Hatchan comments on this as being "outnumbered" compared to his six swords style. In the Funimation adaptations, this is called Gum-Gum Billy Club.


 * Gomu Gomu no Senjukannon (ゴムゴムの千手観音): An alternate version of Gomu Gomu no Gatling with the name being a pun on Gomu Gomu no Cannon. Senjukannon is a thousand-armed Guanyin/Kannon goddess of mercy. Used in the fourth one-hour special.


 * Gomu Gomu no Gomu Doryoku (ゴムゴムのゴム動力): Luffy twists his arms around each other as if to do Gomu Gomu no Tsuchi, then grabs onto a propeller and spins his arms, increasing the power of the propeller. The move greatly exhausts him, however, probably because it requires him to submerge his arms in water, triggering his Devil Fruit weakness. This was first seen being used in the seventh movie, although the concept was seen during the anime version of the Donut Race in the Davy Back Fight arc.


 * Gomu Gomu no Twin Pistol (ゴムゴムのツインピストル): Basically, Luffy's normal Pistol attack, only with both of his arms instead. This was first seen used against Campacino and Brindo. Unlike his normal Pistol attack however, there is no kanji written for this attack. In the Funimation adaptations, this is called Gum-Gum Twin Pistol.


 * Gomu Gomu no Hyakuman-do Bazooka (ゴムゴムの百万度バズーカ): Basically, a regular Gomu Gomu no Bazooka technique that was used by Luffy against Don Accino. The technique differs a little from a regular Bazooka technique, however, as at the moment of impact, Luffy continued applying force to the attack despite his hands being burned by the powers of Don Accino's Devil Fruit, the Atsu Atsu no Mi. As a result, Luffy was able to practically use Accino's own Devil Fruit powers against him by allowing the heat being accumulated into his arms as he maintained contact with the Don's body to build-up, thus allowing Luffy to send Accino flying away into his house, Lovely Land. In the Funimation adaptations, this is called Gum-Gum Million-Degree Bazooka.


 * Gomu Gomu no Ricochet (ゴムゴムのリコチェット): Luffy uses both of his arms and legs to rapidly having them bouncing on the surface of the area to attack multiple opponents, similar to Gomu Gomu no Tako Hanabi. This is first seen against the other Impel Down guards, while trying to rescue Ace. In the Funimation adaptations, this technique is called Gum-Gum Ricochet.


 * Gomu Gomu no Midare Gui (ゴムゴムの乱れ食い): Luffy rapidly stretches his neck to grab multiple items, such as meat, in his mouth. This was used in the One Piece x Toriko crossover special. The kanji used (食い) is often a Japanese term for a fishbite on a fishing line.

Video Game Only Techniques
In the several One Piece video games, Luffy was given several techniques and moves, the known named techniques that are exclusive to the video games are as follows:


 * Gomu Gomu no Bakazu?! (ゴムゴムのバカズ?!): An alternate-pun-named version of Gomu Gomu no Bazooka seen in Dragon Dream!, where Luffy instead shoots out both fists in an underhanded fashion as opposed to palming forward like with the original attack, likely due to his memories being jumbled along with the others' and forgetting how to truly use this attack.


 * Luffy Punch (ルフィパンチ): A standard, short-ranged, non-stretching punch with Luffy's right arm. Serves as the starting input for his Front Attack strings. Present in Grand Battle!, Grand Battle! 2, One Piece: Grand Battle! 3, One Piece: Grand Battle! Rush! and One Piece: Grand Adventure (Grand Battle series).


 * Luffy Swing (ルフィスイング): A standard, short-ranged backhanded swing of Luffy's left arm aimed vertically upward. Serves as the starting input for his Up Attack strings. Present in the Grand Battle series.


 * Gomu Gomu no Masakari (ゴムゴムのまさかり): A technique different from Gomu Gomu no Ono and is more akin to a vertical Gomu Gomu no Muchi which is a vertical-based stretched leg swing downwards (normally while airborne). Used as his base Up Attack base string finisher in the Grand Battle games (via 3, Rush! and Grand Adventure) where he swings to strike with the heel of his foot from above while airborne, and as his midair up special in Battle Stadium D.O.N. where he tumbles away a bit and strikes with a back-to-front-backflip-stretch kick forward. Masakari (鉞) is the Japanese name for a broadaxe, but if written as 真盛り means either "in the height/middle of a full bloom". In the localized Grand Battle and Grand Adventure, it is called Gum Gum Battleaxe.
 * A similar move, though unnamed, also appears in his J-Stars Victory Vs. move set as his weak-to-strong string finisher and base strong attack string finisher.


 * Gomu Gomu no Dance (ゴムゴムの): A special move that combines several of Luffy's attacks, starting with Gomu Gomu no Kane, Gomu Gomu no Pistol, Gomu Gomu no Muchi, and with Gomu Gomu no Gatling as the finisher (along with its video game-signature finishing Pistol-like punch. This group of techniques is the same used by Luffy against Arlong during the beginning of their second fight. Present in the Grand Battle series, this is a Lv. 2 super in Grand Battle and Grand Battle 2, and a Lv. 1 super in Grand Battle 3, Rush! and Grand Adventure (where in those cases, he instead performs multiple turning strikes, rotating between both Pistol and Muchi, then propels himself in a leap for a diagonally downward aerial Gatling that can be button-tapped for more hits). In the localized titles, this move is called Gum-Gum Dance.
 * Unlike Luffy's other supers in Grand Battle! Rush and Grand Adventure, this move is the only one that can K.O. an opponent normally at any health amount (his other supers can mysteriously only K.O. an opponent that is already at the lowest HP value possible).


 * Gomu Rush (ゴムラッシュ): A special move that starts off with a Gomu Gomu no Gatling followed up with a Gomu Gomu no Bullet, then finishes with a double Gomu Gomu no Bazooka (the second one becomes delayed and can break guards/become unblockable). Present in both Jump Super Stars and Jump Ultimate Stars as Special Move A for Luffy's 4 koma version, but unlike most versions of Gatling in the video games, the Gatling performed in this move cannot be button-tapped for more hits.


 * Kung Fu Kick (カンフーキック): A unique special action used exclusively by Kung Fu Luffy in One Piece: Burning Blood. Allows Luffy to perform Kung Fu based kicks depending on the button imput.

Post-Timeskip Attacks
This is a list of attacks used by Luffy, that were not seen pre-timeskip, and are also not Haki enhanced. The majority has a gun and artillery concept theme name, with the difference that they also have a reference to a specific animal. Additionally, he made an even stronger version of his original counter technique, as well as an interesting method of fighting which allows him to hover and attack at the same time.

Gun and Artillery Themed Attacks



 * Gomu Gomu no Snake Shot (ゴムゴムの): Luffy uses his Devil Fruit abilities to launch his arm in a swerving snake-like movement and grasp the enemy with an open hand gripping hard enough to cause great pain. Snake shot is a type of lead shot, it is very small, fits typically into a cartridge, and is generally used to shoot at snakes, rodents, and other small animals at very close range. This was first seen used against Hody Jones to break one of his ribs and make him release Shirahoshi's hair from his grip. This is called Gum Gum Snake Shot in the VIZ manga and Funimation adaptations.


 * Gomu Gomu no Orei Fire (ゴムゴムのお礼): A stronger counter version of Gomu Gomu no Fusen, Luffy first absorbs the gunshots the way he does normally and then accurately rebounds the bullets right back at the enemy with twice the power as when they hit him. When he used this technique, Luffy put the thumb and forefinger of each hand together to form a rectangle with a crosshair similar to Chopper's Scope ability. This was first used against Rock. In the VIZ manga and Funimation adaptations, this is called Gum-Gum Fire Salute.

Haki Enhanced Attacks

 * Buso Koka: Gomu Gomu no Gatling (武装硬化 ゴムゴムの): Luffy uses Busoshoku Haki to harden his fists, greatly increasing the strength of his standard Gomu Gomu no Gatling attack. It was used to shatter an icicle pincushion he was lured into by the Yeti Cool Brothers. In the VIZ manga and Funimation adaptations, this is called Armament Hardening Gum-Gum Gatling.


 * Buso Koka: Gomu Gomu no Bullet (武装硬化 ゴムゴムの): Luffy stretches one arm, far behind him while running, uses Busoshoku Haki to harden the fist at the end of his stretched arm, then snaps it back to deliver a powerful short-distance, one-fisted blow to an opponent's abdomen. It was used to deal a crippling blow to Hody Jones, sending him flying into a cliffside with enough force to shatter it. It was unnamed in the manga, though in Episode 558, it was referred to as Gum-Gum Bullet.

Other Concepts and Themed Attacks



 * Gomu Gomu no UFO (ゴムゴムの): Luffy twists back his legs midair, and lets them go, causing them to spin around and around horizontally similar to a discus, occasionally lashing out with his legs and kicking anyone within reach. Using this technique seems to allow him to hover a few feet off the ground and also seems to have a cutting affect. This was first used against some of Caesar Clown's subordinates. This is called Gum-Gum UFO in the VIZ manga and the Funimation adaptations.


 * Gomu Gomu no Tsuppari (ゴムゴムのつっぱり): Luffy strikes his opponent with an open, slightly enlarged hand. It was first used in a sumo wrestling match against Urashima. Tsuppari is a form of harite (open hand) strike used in sumo wrestling. This is called Gum-Gum Sumo Slap in the VIZ manga and Funimation adaptations.

Haki Enhanced Attacks



 * Atama Buso: Gomu Gomu no Kane (頭武装 ゴムゴムの鐘): Luffy uses Busoshoku Haki to harden his forehead and gives a powerful stretched headbutt to the opponent. A much stronger version of his standard Gomu Gomu no Kane attack that was able to shatter the iron shields of the New Fish-Man Pirates' Iron Shell Squad. This was first used against the New Fish-Man Pirates' Iron Shell Squad. In the VIZ manga this is called Head Armament Gum-Gum Bell. In the Funimation adaptations, this is called Head Hardening Gum-Gum Bell.


 * Gomu Gomu no Tako Stamp (ゴムゴムのタコスタンプ): Luffy hardens his legs, down to and including his sandals, and kicks in a manner similar to Gomu Gomu no Stamp Gatling. This technique was first used in the fight against Doflamingo and the controlled Bellamy, when Luffy was down on the ground with his hands tied behind his back.

Anime Only Attacks

 * Gomu Gomu no Spread (ゴムゴムのスプレッド): A Haki-enhanced version of Gomu Gomu no Pistol, in which Luffy enhances the punch with Busoshoku Haki followed by his trademark extended punch. It was used against the Big Toro, immediately followed by a Gomu Gomu no Stamp and Gomu Gomu no Kane. The Funimation adaption of the special however, refers to this technique as Gum-Gum Bullet instead.


 * Gomu Gomu no Spring Bullet (ゴムゴムのスプリング): Luffy coils his legs and hardens them with Busoshoku Haki to increase their tensile strength, allowing him to bounce from surface to surface in order to build up momentum for a Haki-hardened punch. This was first used against Doflamingo. It is an homage to Bellamy's Spring Hopper technique.


 * Gomu Gomu no Suika (ゴムゴムのスイカ): Luffy stretches out both his hands to grab what he thought to be a giant watermelon which was floating on the sea, which later turns out to be a Fruit Footballfish. In the Funimation dub, this attack is called Gum-Gum Melon Grab and Gum-Gum Waterlmelon in the subs.


 * Gomu Gomu no Suika-wari (ゴムゴムのスイカ割り): After Luffy was swallowed whole by a watermelon type Fruit Footballfish, Luffy kicks upwards, bursting his foot out of the sea creature, before bringing it down in a similar manner as Gomu Gomu no Ono, completely breaking the fish into pieces. In the Funimation dub, this attack is called Gum-Gum Watermelon Splitter and Gum-Gum Waterlmelon Splitting in the subs.


 * Gomu Gomu no Eda (ゴムゴムの枝): With Charlotte Brûlée taken as a hostage, Luffy used her as a human shield from her sisters Mondée and Effilée on Nuts Island. The name comes from Luffy's habit of calling Brûlée "Branch", much to her chagrin, and she angrily corrects him after he calls out the attack. In the Funimation adaptations, this attack is called Gum-Gum Branch.

Situational Attacks
During certain situations, Luffy is sometimes forced to adapt in his use of his Devil Fruit powers in order to fight an enemy. This is usually due to an attack inflicted by an enemy on him that leaves him at a disadvantage. To compensate, Luffy thus adapts to the situation and turns his disability into an advantage instead.




 * Gomu Gomu no Tonkachi (ゴムゴムのトンカチ): A technique that Luffy had to temporarily come up with while on Little Garden. While the Straw Hat Pirates were on Little Garden, they faced off against four of Baroque Works' Officer Agents; Mr. 5, Miss Valentine, Miss Goldenweek, and Mr. 3. Mr. 3 has the power of the Doru Doru no Mi, which allows him to produce and control a wax-like substance from his body. He used this wax power several times to wrap a large wax cylinder around Luffy's feet and then later arm. Instead of slowing Luffy down, Luffy actually uses the wax cylinder to his advantage. Using it like a hammer, he first destroyed the pole on Mr. 3's wax creation with a cylinder wrapped around his feet. Luffy then later broke through Mr. 3's Candle Wall and pounded Mr. 3 himself with a cylinder on his arm. The cylinders that bound Luffy's feet and arm both broke upon impact. This technique is called Gum-Gum Hammer in the VIZ manga and Gum-Gum Mallet in the Funimation adaptations.


 * Gomu Gomu no Hanabi: Ogon Botan (ゴムゴムの花火・黄金牡丹): During Luffy's fight with Enel, Enel encased Luffy's arm in a Golden Ball he created by melting some gold with his Gloam Paddling technique. With this, Enel hoped to hinder Luffy's actions as he tossed him overboard the Maxim. Luffy however, despite burdened with this huge cumbersome object, was able to still move about and use his burden to his advantage in two techniques that he had to temporarily come up with. The first of these is Gomu Gomu no Hanabi: Ougon Botan. It is the same as Gomu Gomu no Hanabi, but with the Golden Ball attached to his arm. This technique was used against Enel's Raigo. By swinging the Golden Ball around, Luffy was able to use it as a conductor to destroy the storm cloud. The lightning all zapped through the ball and was discharged. In the VIZ manga and Funimation dub, this is called Gum-Gum: Golden Peony and in the Funimation sub it is called Gum-Gum: Gold Peony. According to Oda in a response to a fan in a SBS, Luffy himself did not exactly know what he was doing when he did this technique. According to a fan poll, this is the nineteenth most favorite attack amongst fans with a total of 111 votes. A (tree) peony is a type of flower known as the Paeonia suffruticosa, or a moutan.


 * Gomu Gomu no Ougon Rifle (ゴムゴムの黄金): The same as Gomu Gomu no Rifle but with the Golden Ball attached to his arm. This move possesses much more speed than a regular Gomu Gomu no Rifle in that it creates a massive sonic boom when used. After destroying Enel's Raigo with the Golden Ball, Luffy used this technique to defeat Enel and ring the Shandorian Golden Belfry Bell. This was so fast that even though Enel's Mantra ability could detect it, this was too fast for Enel to avoid. With this technique, Luffy was also able to break the Golden Ball encasing his arm as the ball hit the bell. In the VIZ manga and Funimation dub, this is called Gum-Gum Golden Rifle and in the Funimation sub it is called Gum-Gum Gold Rifle. According to a fan poll, this is the thirteenth most favorite attack amongst fans with a total of 327 votes.


 * Gomu Hook (ゴムフック): While in his "Afro Luffy" form, Luffy launches an elongated hook, which can hit the enemy’s back due to his stretching ability. This was first used against Foxy. In the VIZ manga and the video game Grand Adventure (dubbed by 4Kids), this move is called Gum Hook.




 * Gomu Gomu no Flail (ゴムゴムの): Luffy swings one arm in a circle at high speed, then drives his fist into his opponent. This was first used against Foxy. In the VIZ manga and Grand Adventure, this is called Gum-Gum Flail.

Situational Forms
Throughout the series, Luffy is often faced with opponents that require unusual methods to defeat. For this reason, he sometimes adopts certain "forms" aside from his "Gear" forms intended to enable him to defeat those enemies.

Mizu Luffy


In the fight with Crocodile, the leader of Baroque Works, Luffy used a barrel filled with water in order to weaken Crocodile and make him vulnerable by disabling his ability to transform into sand. With this, Luffy could coat his appendages with water and use water-supported attacks against Crocodile, along with a plan to soak Crocodile completely with water. However, upon realizing the barrel and its contents were in too much danger from Crocodile's attacks, Luffy drank the entire barrel of water, becoming Mizu Luffy (水ルフィ). Though at first glance the form looks idiotic and somewhat flawed as he had trouble keeping the water down (to the point of causing even the enemy Nico Robin to burst out laughing), it allowed Luffy to safely store the water and spit it out at Crocodile for use. Luffy stayed in this form until he was completely dried up by Crocodile. In the Funimation dub, the form is called Water Luffy.

The known Devil Fruit attacks that Luffy uses in this form are as follows:


 * Mizu Mizu no Pistol (水水の): By drinking a barrel of water and becoming "Mizu Luffy", Luffy pumps water into his mouth with his arms before he spits spheres of water at his opponent. This was first seen being used against Crocodile. Aside from Luffy's regular Devil Fruit techniques enhanced by water while in this form, this is the only named technique used by Luffy unique to this form. In the VIZ manga and Funimation dub, this is called Water-Water Pistol and in the 4Kids dub, it is called Water-Water Blast.

Trivia

 * In the 3rd movie, it is shown that Luffy will not sink in water in his Gomu Gomu no Fusen technique. It is also seen in the anime.
