Gomu Gomu no Mi

The Gomu Gomu no Mi, also known as the Gomu Gomu Fruit, is a Paramecia type Devil Fruit that turns the user's body into rubber. "Gomu" means rubber in Japanese. This Devil Fruit is a large violet cherry like shaped fruit with swirls. In the 4kids dub and Viz manga, it is called the Gum Gum Fruit. It was originally a treasure that Shanks and his crew took from an unspecified enemy but was accidentally eaten by Monkey D. Luffy. In the second version of Romance Dawn, it originally belonged to Luffy's grandpa who took it from an unspecified enemy.

Strengths and Weaknesses
The fruit's major strength, as demonstrated by Luffy, is that the person can stretch their body like rubber at will, and makes them almost entirely immune to blunt attacks, including bullets or even cannonballs. Owing to Rubber's insulating properties, the user is also immune to electrical attacks.

By training his Gomu Gomu abilities, Luffy has found unexpected ways to increase his fighting ability, such as the ability to stretch his blood vessels wider to allow more oxygen and nutrients to get to other parts of the body allowing him to become faster and stronger, at a cost of depleting his body's energy. Luffy can even inflate his bones to increase the mass of his body and power up his attacks.

Despite all the advantages Luffy gets by using his fruit, he can however still be hurt by cutting or stabbing attacks, as well as non-physical attacks such as fire or ice. Of course, he also suffers the same weaknesses to water and Seastone as other Devil Fruit users. One risk of Luffy's powers is that he is vulnerable attack in the moments when his limbs are stretched to their limit-- Luffy, however, has adapted his fighting style to minimize this risk.

Usage
The powers of the fruit have been used by Luffy in a variety of ways. These range from simply moving from one place to another in rather reckless manner, to attacking an enemy with a barrage of punches.

Attacks
Luffy notably uses the Gomu Gomu no Mi to attack. His attacks all follow a pattern. They begin with "Gomu Gomu no..." and finish with an attack-specific word. The majority of them are named after guns and various other firearms. This naming pattern originates from the claim that Luffy made to Shanks. He claimed 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. 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.

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 (ゴムゴムの銃(ピストル)): Luffy's standard straight punch, augmented with stretching. This attack can be used from short to long range. In the Viz manga, it is called Gum Gum Pistol. In the 4kids dub, it is called Gum Gum Blast. It's name comes from Luffy's claim to Shanks that his punching arm is "As powerful as a pistol!" This was first seen being used on the Lord of the Coast after ten years of training. 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 Rocket (ゴムゴムのロケット): Luffy's main method of travelling long distances fast. He stretches out his arms and grabs a handhold, then lets them, projecting himself high into the air, 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. This was first seen being used to propel Luffy to the top of the Marine Base in Shell Town. This is called Gum-Gum Rocket in the Viz manga and 4kids dub.


 * 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 simultaneously. This is usually used as a finishing move. This was first seen being used to defeat Buggy. In the Viz Manga, this is called Gum-Gum Bazooka. In the 4kids dub, this is called Gum-Gum Double Barrel. According to a fan poll, this is the fifth favorite attack amongst fans with a total of 995 votes.


 * Gomu Gomu no Gattling (ゴムゴムの銃乱打(ガトリング)): Luffy uses his stretching ability to bring his fists forward repeatedly in a blurry, rapid barrage of weak punches that creates the illusion of him having multiple arms. This was first seen being used against a group of Black Cat Pirates. Usually only used against weaker opponents or when Luffy is becoming frustrated, as it has little effect on stronger enemies. In the Viz Manga, this is called Gum-Gum Gattling. In the 4kids dub, this is called Gum-Gum Rapid Fire. According to a fan poll, this is the favorite attack amongst fans with a total of 3785 votes.


 * Gomu Gomu no Bullet (ゴムゴムの銃弾(ブレット)): Luffy stretches one arm far behind him, then snaps it back to deliver an short-distance, one-fisted blow to an opponent. This was first seen being used on Don Krieg. In the Viz Manga, this is called Gum-Gum Bullet, while in the 4kids dub, this is called Gum-Gum Burst. According to a fan poll, this is the twenty eighth favorite attack amongst fans with a total of 68 votes.


 * Gomu Gomu no Bow Gun (ゴムゴムのボーガン) / (Gum-Gum Crossbow): Luffy takes hold of his opponent, then repeatedly twists his torso vertically around his waist. The resulting snapback sends his opponent flying.


 * Gomu Gomu no Shotgun (ゴムゴムの銃(ピストル)｢散弾(ショット)｣): Starts off as an ordinary Pistol attack, after which Luffy "twangs" his stretched arm, causing his fist to connect multiple times. The kanji can be read as "Pistol Shot" but it is pronounced as "Shotgun" in the anime. In the 4kids dub, this is called Gum-Gum Quake. This was first seen being used against Crocodile after Luffy wet his own body with water.


 * Gomu Gomu no Rifle (ゴムゴムの回転弾(ライフル)) / (Gum-Gum Drill): Similar to Gomu Gomu no Pistol, but Luffy twists his arm around as he stretches it behind him and hits the opponent at close range, putting a spin on them. According to a fan poll, this is the tweenty first favorite amongst fans with a total of 85 votes.


 * Gomu Gomu no Cannon (ゴムゴムの攻城砲 (キャノン)): Luffy builds up speed with a long series of quick punches, and finishes with a single double-fisted blow. A powerful technique that can pierce strong armour.

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 Shell Town. This is called Gum-Gum Whip in the Viz manga and 4kids dub.


 * Gomu Gomu no Tsuchi (ゴムゴムの槌, Rubber Rubber Mallet): Luffy takes hold of his opponent with his hands, then spins, twisting his arms. 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 Shushu's master's store. In the Viz manga, this is called Gum-Gum Gavel. In the 4kids dub, this is called Gum-Gum Hammer.


 * 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. In the Viz Manga, this is called Gum-Gum Sickle. In the 4kids dub, this is called Gum-Gum Fist.


 * Gomu Gomu no Yari (ゴムゴムの槍): Luffy holds his feet together and kicks with both simultaneously. This was first seen being used against Kuro after Luffy dodged his attack. This is called Gum-Gum Spear in the Viz Manga and 4kids dub.


 * Gomu Gomu no Ōgama (ゴムゴムの大鎌): Identical to Gomu Gomu no Sickle, but he uses both arms for the rocket and the clotheslining. This was first seen being used on a group of Krieg's pirates that were attacking the Baratie. This is called Gum-Gum Giant Scythe in the Viz Manga and 4kids dub.


 * Gomu Gomu no Ono (ゴムゴムの斧) Luffy stretches one leg high into the air, then brings it crashing down on an opponent or structure, for massive damage. This was first seen being used on the front porch of the Baratie. In the Viz Manga, this called Gum-Gum Axe. In the 4kids dub, this is called Gum-Gum Battle Axe.


 * Gomu Gomu no Ōzuchi (ゴムゴムの大槌, Rubber Rubber Giant Mallet) / Gum-Gum Giant Hammer: Similar to Gomu Gomu no Gavel, but he performs it using the feet and legs instead of hands and arms.

Other Concepts 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 Fuusen (ゴムゴムの風船): A technique wherin 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 to their shooters. This is not necessarily always an attack as Luffy can also use this technique for other purposes aside from deflecting projectiles. 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 4kids dub. 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 grappled onto an enemy, Luffy stretches his neck backwards, then snaps it back for a devastating head butt to the opponent's face. This was first seen being used to defeat Kuro. This is called Gum-Gum Bell in the Viz Manga and 4kids dub.


 * Gomu Gomu no Kazaguruma (ゴムゴムの風車) / Gum-Gum Windmill (Gum-Gum Pinwheel): 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 Sea King and unwound, spinning the Sea King around rapidly to crush the entire Fishmna crew.


 * Gomu Gomu no Tate (ゴムゴムの盾) / Gum-Gum Shield: Luffy grabs the fingers of one hand with the other, and stretches them before his face to block blades that pass between the fingers. Used on Arlong.


 * Gomu Gomu no Ami (ゴムゴムの網, Rubber Rubber Net) / Gum-Gum Finger Net: 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.


 * Gomu Gomu no Ikebana (ゴムゴムの生け花, Rubber Rubber Flower Arrangement) / Gum-Gum Bouquet: Luffy grabs hold of the Going Merry's mast and slams it into his opponent. Was used on Laboon first.


 * Gomu Gomu no Stamp (ゴムゴムのスタンプ) / (Gum-Gum Stamp): Luffy stretches his leg out and hits his opponent with the bottom of his foot, leaving an imprint, or "stamp", of his sandal.


 * Gomu Gomu no Suishinki (ゴムゴムの推進器, Rubber Rubber Propeller) / (Gum-Gum Twister): Used against a giant sea bird, Luffy jumps into the air and does a Gomu Gomu no Gavel, spinning the bird around in a cyclone before slamming down onto the Going Merry.


 * 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. In the 4kids dub, this is called Gum-Gum No Way!, Gum-Gum Stay Away!. According to a fan poll, this is the tweenty fourth favorite attack amongst fans with a total of 76 votes.


 * Gomu Gomu no Sensuikan (ゴムゴムの潜水艦) / (Gum-Gum Submarine): Similar to the Pistol, but his fist travels underground to uppercut the target.


 * 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 4kids dub, this is called Gum-Gum Munch-Munch. This technique was first seen being used against Crocodile.


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


 * Gomu Gomu no Storm (ゴムゴムの暴風雨(ストーム): This is easily Luffy's strongest attack without entering Gears Second or Third. Luffy begins by launching his opponent into the air. Luffy then uses Gomu Gomu no Balloon and twists his body around tightly, then blows the air towards the ground. This propels Luffy spinning upwards, where he delivers a flurry of punches similar to Gatling, only much more devastating. 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 feet into the air. Luffy has a another version of this attack where, after launching himself high into the air, he proceeds to rain a barrage of punches downwards him instead of above, devastating hordes of adversaries below him. In the 4kids dub, 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.


 * Gomu Gomu no Hanabi (ゴムゴムの花火) / (Gum-Gum Fireworks): Luffy jumps into the air and spins around rapidly. Then he unleashes a flurry of punches and kicks that go in every direction due to the spinning motion.


 * Gomu Gomu no Boh... (ゴムゴムのボー, Rubber Rubber Idio...): Luffy 'switches off' his conscious mind, allowing him to avoid attacks entirely on instinct. This makes him immune to Enel's mind-reading Mantra ability. The disadvantage is that he can neither think nor attack in this state. According to a fan poll, this is the tweentieth favorite attack amongst fans with a total of 95 votes.


 * Gomu Gomu no Tako (ゴムゴムのたこ, Rubber Rubber Octopus): All of Luffy's appendages go limp reducing the damage he takes.


 * Gomu Gomu no Tako Hanabi (ゴムゴムのたこ花火, Rubber Rubber Octopus Fireworks): Much like Gomu Gomu no Hanabi except, due to the previous move, his limbs bounce off of walls without losing speed. Because his limbs are limp, even Luffy can't predict (much less a mantra-using opponent) or control where they will go if they ricochet off of an object.


 * Gomu Gomu no Mikata Robo (ゴムゴムの味方ロボ, Rubber Rubber Ally Robot): Luffy wraps his arms around a person's limbs in order to manipulate their movements.
 * Mikata Robo Punch (味方ロボパンチ, Ally Robot Punch): Luffy uses his "Ally Robot" to punch an opponent.
 * Mikata Robo Kick (味方ロボキック, Ally Robot Kick): Luffy uses his "Ally Robot" to kick an opponent.


 * Gomu Gomu no Kazan (ゴムゴムの火山 (かざん), Rubber Rubber Volcano): Similar to Gomu Gomu no Ono, except Luffy's foot is stretched upwards to break through a roof.

Anime Uses
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 Neji (ゴムゴムのネジ, Rubber Rubber Screw): 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 ablilty's limit, then slams the object into a foe while spinning. This was first seen being used against Bear King in the first One Piece movie.


 * Gomu Gomu no Amidori (ゴムゴムの網取, Rubber Rubber Net-Catch): 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 unonscious Apis adrift on her boat. The recoil of this technique is somewhat reckless as Luffy's arm pushed Zoro off the Going Merry as Luffy reeled it back in.


 * Gomu Gomu no Tsuribashi (ゴムゴムの吊橋, Rubber Rubber Suspension Bridge): 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.


 * Gomu Gomu no Nagenawa (ゴムゴムの投げ縄, Rubber Rubber Lasso): 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 Ryuji's raft.


 * Gomu Gomu no Tomozuna (ゴムゴムの艫綱, Rubber Rubber Ship to Ship Line): Luffy stretches both of his arms between the ship he is on and the one he wants to go to. By jumping off the ground, he is able to pull himself and passengers to the ship that he is holding onto.


 * Gomu Gomu no Pachinko (ゴムゴムのパチンコ) / (Gum-Gum Slingshot): Luffy grabs hand and foot holds, then intercepts a projectile, stretching back and firing the projectile back at its origin.


 * 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.


 * Gomu Gomu no Sadowari (ゴムゴムの砂土割り (さどわり), Rubber Rubber Sand Splitter)


 * 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 (ともつな), Rubber Rubber Stern Rope)


 * Gomu Gomu no Warp (ゴムゴムのワープ)


 * Gomu Gomu no Propeller (ゴムゴムのプロペラ)


 * 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 homerun.


 * 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 Fuusen.


 * Gomu Gomu no Hittakuri (ゴムゴムのひったくり)


 * Gomu Gomu no Koma (ゴムゴムの独楽, Rubber Rubber Top)


 * Gomu Gomu no Jutte (ゴムゴムの十手): While wielding a jutte, Luffy uses Gomu Gomu no Gattling. Used in the fourth one-hour special.


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


 * Gomu Gomu no Gomu Douryoku (ゴムゴムのゴム動力, Rubber Rubber Rubber Powered): 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.

Forms
Throughout the series, Luffy would sometimes change his "form" per say to fight. This is either in order to match up to an opponent he couldn't beat against under normal circumstances, or for the share sake of it. The most revolutionary of these forms so far is his gear forms in which he makes use of his rubbery body to the fullest. These Gear forms closely follows a popularly used manga concept that is popularly recognized as being based on the Super Saiyan forms from Dragon Ball.

The named forms that Luffy has so far used are as follows:

Mizu Luffy
In the fight with Sir Crocodile, the leader of Baroque Works, Luffy used a barrel filled with water, in order to weaken Crocodile and make him vulnerable by disabling to use his sand-morphing ability. With this Luffy could coat his appendages with water and use water-supported attacks against Crocodile. However upon realizing the barrel and it's contens were in too much danger from Crocodile's attacks, Luffy later swallowed the entire barrel of water, becoming Mizu Luffy. Though the at first glance the form looks idiotic and somewhat flawed, the form however allowed Luffy to safely store the water and spit it out at Crocodile for use. Luffy stayed in this form until he was complety dried up by Crocodile.


 * Mizu Mizu no Pistol (水水の銃(ピストル), Water Water Pistol): By drinking a barrel of water and becoming "Mizu Luffy", Luffy 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 the only named attack used by Luffy unique to this form.

Afro Luffy
During the Davy Back Fight arc, Luffy had to face Foxy the Silver Fox in the final event, Combat. Beforehand, he got to choose what he would wear for the fight. Usopp, who was with him, spotted a big black afro, and had Luffy wear it. Thus, Afro Luffy was born.

Usopp claims that the afro gives Luffy extra power. Indeed, everyone (except for Nami, and possibly Zoro) believed this fact to be true, even Robin (although it is likely that she may have just been playing along). Luffy's appearance also changes, as in the fight, he also wears boxing shorts, boxing gloves, some type of straps on his feet, and has a temporary tattoo of a flaming skull and cross-bones on his chest. Also he also tends to say things such as "Hell yeah!".

Although this form only appears once in the original manga, Afro Luffy returns again in a filler episode. When Foxy tries to get his ship and crew back, he is forced to ask for Luffy's help. When doing so, he hands over the afro he had before, and Luffy uses it to fight.

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


 * Gomu Gomu no Hook (ゴムゴムのフック): Luffy launches an elongated hook, which can hit the enemy’s back due to his stretching ability.


 * Gomu Gomu no Flail (ゴムゴムの連接鎚矛(フレイル)): Luffy swings one arm in a circle at high speed, then drives his fist into his opponent.

Gear Second
A form that was first seen in Luffy's fight against Blueno. Luffy pumps his blood rapidly with his legs kickstarting the process, increasing his blood flow, thus providing more oxygen and nutrients to various parts of his body which makes him faster and stronger; Lucci compares the process to taking a stimulant. In Luffy's case, all of his organs are rubber, so they can expand and allow the blood to move at the increased speed without stressing any one internal organ and causing it to explode. This mode's enhancements to Luffy's physiology gives him the ability to use a new set of attacks which are generally the same as his old ones but now are so fast that even a skilled assassin would have a hard time actually seeing them. In this form his metabolism rate is so high that his sweat vaporises rapidly giving rise to a steaming appearance, and his skin turns slightly pink from the increased blood flow.

Currently Luffy can only use Gear Second for a short period of time, because the accelerated speed at which nutrients are used up depletes his stores rapidly. The mechanics behind this enhancement also mean reduced strength and ability after significant amounts of usage (with nutrient stores running low, having a faster blood flow would be quite pointless since there are no nutrients to deliver), as pointed out by Lucci when Luffy's attacks start losing their speedy edge. After gear second wears off, Luffy can recover quickly through replenishing of his nutrient storage by eating meat.

Also, while not considered canon, in the 7th movie of the series which takes place before the Water 7 arc, Luffy briefly and unknowingly activated Gear 2 during his fight against Ratchet, the antagonist of the film, showing this to be the move's origin of sorts.

The known named techniques that are used by Luffy so far in this form are as follows:


 * Gomu Gomu no Jet Pistol (ゴムゴムの JET銃[ピストル]): Luffy delivers a Gomu Gomu no Pistol so fast that the fists' movement is invisible, and it truly seems like he shoots his opponent, except that the resulting impact is not akin to an actual pistol, but to a small hand-held cannon abd powerful enough to propel the unlucky recepient several meters away. The incredible speed both makes the strike more powerful, and harder to dodge. This was first seen being used against Blueno.


 * Gomu Gomu no Jet Stamp (ゴムゴムの JETスタンプ): Luffy delievers a Gomu Gomu no Stamp, with the same effect as the Jet Pistol. This was first seen being used against Blueno.


 * Gomu Gomu no Jet Bazooka (ゴムゴムの JETバズーカ): Luffy charges at his opponent at high speed, and delivers a very fast and very strong Gomu Gomu no Bazooka. This was first seen being used against Blueno. It was apparently powerful enough to break through Blueno's strongest Tekkai technique.


 * Gomu Gomu no Jet Whip (ゴムゴムの JET鞭[ウィップ]): Luffy delivers a Gomu Gomu no Muchi, so fast, that only the slipstream is visible. This was first seen being used against Rob Lucci in order to protect Franky from him.


 * Gomu Gomu no Jet Bullet (ゴムゴムの JET銃弾[ブレット]): An extremely fast close range punch. The stretchjing of the original Bullet along with the resulting snapback seem to occur almost simultaneously at once, making it virtually inescapable. This was first seen being used against Rob Lucci.


 * Gomu Gomu no Twin Jet Pistol (ゴムゴムの ツインJET銃[ピストル]): Luffy punches with both arms simutaneously. Visually, the move only differs from his bazooka in that instead of doing an open palm strike, he has clenched fists which leave two knuckle shaped imprints on his foe. This was first seen being used against Rob Lucci.


 * Gomu Gomu no Jet Gattling (ゴムゴムの JET銃乱打(ガトリング): This move is the strongest that Luffy has used to date, as seen by the effect on its unfortunate target, Rob Lucci. Luffy stands still, and moves his arms so fast that they become invisible, covering the enemy with punches (each with the force equal to a Jet Pistol) in a mere split second. The hits land so fast that, after a volley, they seemingly connect simultaneously, while a circle of airbursts from the punches surround Luffy. The circle resembles the many barrels of a real gatling gun.


 * Gomu Gomu no Jet Rifle (ゴムゴムのＪＥＴ回転弾): A Gear Second technique that first appeared in the anime. Luffy delievers a very fast Gomu Gomu no Rifle. The winding of the original Rifle along with its snapback happening almost at the same time makes this move impossible to evade. This was first seen in the anime being used against Blueno.


 * Gomu Gomu no Jet Yari (ゴムゴムのＪＥＴ槍, Rubber Rubber Jet Spear): A Gear Second technique that first appeared in the anime. Luffy delievers a very fast Gomu Gomu no Yari. This was first seen in the anime being used against Blueno.


 * Gomu Gomu no Jet Missile (ゴムゴムのＪＥＴミサイル): A Gear Second technique that first appeared in the anime. Luffy stretches and grabs onto an enemy's body. Then, he very quickly retracts, crashing into the foe. This was first seen in the anime being used against Blueno.


 * Gomu Gomu no Jet Axe (ゴムゴムのＪＥＴ斧 ): A Gear Second technique that first appeared in the anime. Luffy stretches his leg vertically and then crashes it down on his opponent. This was first seen in the anime being used against Lucci.

Gear Third
A form that is first seen being used by Luffy to knock down a steel door in Enies Lobby. It was first fully seen in Luffy's fight against Lucci, Luffy corks his mouth with his thumb, bites into his thumb joint and blows very hard into it, which inflates his arm. He is then able to transfer the air through his entire body, requiring the torso to act as an interface for his various limbs. Luffy blows so much air into his body that when they're all focused on a single limb, they become the size equivalent to that of a giant's. Used with his already-strong physiology, this apparently gives his arm more mass and a larger area to attack with, but he sacrifices speed for this strength. The bones are the key difference between this form and his old "Gomu Gomu no Fuusen" move, where his balloon form was soft and squishy like a regular balloon, whereas the inflated bones are very hard, similar to an inflated car tire, to the point of withstanding bullets. The bones being much harder also mean a lot of compression of air takes place when using Gear Third, making Gear Third not just a 'for-show' move as Lucci initially thought, but like a giant mace of astounding mass when used in attacks. In between his attacks, Luffy brings the air back to his chest and then shifts it into another body part. To deactivate Gear Third, Luffy leaves the form by exhaling heavily, which can cause him to be propelled backwards.

The deactivation of Gear Third brings about shrinking (to chibi size), which is a negative side-effect. The amount of time Luffy spends in his shrunken form is roughly equivalent to the amount of time spent in Gear Third mode. This shrunken form has shown no ability to stretch at all, and it has been shown that Luffy loses strength when he kept hitting Lucci's face to no effect. A currently used strategy would be to run and hide from an opponent for the duration of the shrinkage.

The known named techniques that are used by Luffy so far in this form are as follows:


 * Hone Fuusen (骨風船, Bone Balloon): Luffy inflates his body by blowing air into his bones. It seems a more effective defense than the regular balloon, since bullets now ricochet instead of bounce off him. This was first fully shown in Luffy's battle against Rob Lucci.


 * Gomu Gomu no Gigant Pistol (ゴムゴムの 巨人の銃(ギガント･ピストル)): Luffy delivers a Gomu Gomu no Pistol with extremely high amounts of power due to the larger size of his fist. This was first fully seen being used against Rob Lucci. It's sheer power was able to fling him from the Bridge of Hestitation on to a Buster Call Battleship.


 * Gomu Gomu no Gigant Axe (ゴムゴムの 巨人の斧(ギガント･アックス)): Gomu Gomu no Ono with more power due to his enlarged foot and leg. This was first seen being used against Rob Lucci. It's sheer power is able to damage and create a hole in the deck of a Buster Call Battleship.


 * Gomu Gomu no Gigant Whip (ゴムゴムの 巨人の鞭ギガント･ウィップ)): Gomu Gomu no Muchi with more power due to his enlarged foot and leg. This was first seen being used against Rob Lucci. It's sheer power is able to damage the mast of a Buster Call Battleship.

Situational Cases
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 because 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 disablility into an advantange instead.

The known techniques that Luffy has had to create under such circumstances and their origin are as follows:


 * Gomu Gomu no Tonkachi (ゴムゴムのトンカチ, Rubber Rubber Hammer): 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 clyinder to his advantage. Using it like a hammer, he first destroyed the pole on Mr. 3's wax creation with a cylinder wraped 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 binded Luffy's feet and arm both broke upon impact.


 * Gomu Gomu no Hanabi: Ougon Botan (ゴムゴムの黄金牡丹, Rubber Rubber Fireworks: Golden Peony): The same as Gomu Gomu no Fire Works, but with a Golden Ball attached to his arm. According to a fan poll, this is the nineteenth favorite amongst fans with a total of 111 votes.


 * Gomu Gomu no Ougon Rifle (ゴムゴムの黄金回転弾, Rubber Rubber Golden Rifle): The same as Gomu Gomu no Rifle but with a Golden Ball attached to his arm. This move possesses much more speed than a regular Gomu Gomu No Rifle in that it creates a Sonic Boom when used. Used in his fight against Eneru. According to a fan poll, this is the thirteenth favorite amongst fans with a total of 327 votes.

Team Combinations
At certain times, Luffy would use his Devil Fruit powers in team combos with his crew. This is in relation to his bonds of friendship and comradery with the rest of them. The known named techniques that Luffy uses with others are as follows:


 * Army De L'air Gomu Shoot (空軍(アルメ・ド・レール)ゴムシュート, Air Force Rubber Shoot) / (Taffy Trouncer): A combo attack between Luffy and Sanji. Luffy stretches and grabs Sanji's leg, and as Sanji kicks forward, Luffy uses a Gomu Gomu no Rocket, propelling him forward at higher speeds than normal.


 * Gomu Gomu no 300 Pound Cannon (ゴムゴムの三百煩悩(ポンド)攻城砲(キャノン), Rubber Rubber 300 Pound Cannon): A combo attack between Luffy and Zoro. Luffy and Zoro use the Gomu Gomu no Cannon and the 108 Pound Cannon at the same time. This is actually a 216 Pound Cannon, but Luffy decided that name was too long and hard to pronounce.


 * 600 Million Belly Jackpot (６億Ｂ・ＪＡＣＫＰＯＴ(6おくベル・ジャックポット)): A combo technique that is done with Luffy, Zoro, Sanji, Robin and Franky against a large group of opponents. The five of them attack in all directions, taking out the entire group. In here, Luffy is seen using one of his trademark punches in conjuction with his crew. This was first seen being used against a group of Zombies.


 * Gomu Gomu no Kaiten Ono (ゴムゴムの回転斧, Rubber Rubber Spinning Axe): Anime only. A combination of moves executed by Luffy, Zoro, Sanji, and Usopp. Luffy executes Gomu Gomu no Fusen (ゴムゴムの風船) as well as twsiting his body, using the stored air to launch himself into the air. Then, Usopp abord the Merry-Go fires a canonball at Sanji, while Luffy shoots both of his arms towards the target. Sanji at this point Armeé de L'air Power Shoots the canonball at Zoro who executes 108 Pound Cannon (百八煩悩鳳) to fire the canonball up into the air and toward Luffy. Luffy catches the ball with his feet, the inertia of the canonball spinning him vertically several times causing his legs to twist with each revolution. After all of the canonball's inertia is gone, Luffy drops it and proceeds to spin forward releasing the full force of the stored energy from the winding, his body falling towards the target during all this. As Luffy approaches the target he stretches his legs out, which, through the speed of his spinning, creates the image of a large rotary blade. This attack impacts with the target, cutting it in half. The force of this seems out of Luffy's control.


 * Kame Hame Gomu Gomu no BazooHa (かめはめゴムゴムのバズー波): A combo technique that Luffy used with Goku in the special One Piece and Dragonball crossover comic, Cross Epoch, against Buggy and Emperor Pilaf's Tettiri No.55. In here, Luffy uses a Bazooka technique in conjuction with Goku's Kamehame Wave. The name of this technique is a combination of their attack names.


 * Gomu Gomu No Kame Hame Ha (ゴムゴムのかめはめ波): A combo technique that Luffy used with Goku in the One Piece/Dragonball Special against Eneru.

Early One Piece
Oda rewrote several details about the Gomu Gomu no mi in his early version of One Piece Romance Dawn V.1 and Romance Dawn V.2. In V.1, the Devil Fruit the fruit was the same except the Gomu Gomu no mi was the fruit of the Gomu Gomu tree which grew once every 50 year and there were no named attacks in V.1. In V.2 the first named attack is given, however rather say "Gomu Gomu..." at the start of all his moves, Luffy simply said "Right hand stopper!". Little detail was given on the Devil Fruit itself in V.2.
