Gomu Gomu no Mi

The Gomu Gomu no Mi is a Paramecia type Devil Fruit that turns the user's body into rubber. "Gomu" means rubber in Japanese. In the Viz Manga and 4Kids and FUNimation dubs, 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 series protagonist Monkey D. Luffy. In the second version of Romance Dawn, it originally belonged to Luffy's grandpa who took it from an unspecified enemy.

Appearance


The Gomu Gomu no Mi is a violet, spherical fruit with a root sprouting out of the top, with swirls that go in a curly "S" pattern. It overall resembles a Yubari Melon. While its final design has the characteristic Devil Fruit swirls all over it, the fruit was initially drawn without them in the first version of Romance Dawn.

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. The user's rubber body also allows the user to survive falls from heights that would kill a normal person. The user's ability to stretch and twist like rubber to extreme lengths not only makes them immune to injuries that originate from such, but it also allows them moves that can give them a great advantage in battle or otherwise. Stretching also allows the user to drastically increase the range of what would otherwise be considered a powerful close-range attack, turning it into a devastating mid-range or long-range attack. A stretched limb can also be used to store potential energy like a stretched spring, increasing the power of an attack. Combined with Haki, his power is increased even more. Owing to rubber's insulating properties, the user is also immune to electrical attacks and is also able to hit electric Logia users without Haki.

In the anime, Luffy has used his stretching abilities to inhale great amounts of air to thus exhale a big gust of wind; this application of his powers was used to blow away Marigold's poisonous smoke from her venom spit and Magellan's poison breath.

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 increase the speed of his blood flow in order to become faster and stronger, at a cost of depleting his body's energy at a faster rate. Luffy can even inflate his bones to increase the volume of his body and significantly increase his attacks, at the cost of his body becoming smaller for a short period of time. Although after the timeskip Luffy has seemingly been able overcome this weakness as after he used Elephant gun on the Kraken and he didn't revert to his smaller size afterwords he like usually would before the timeskip.

Despite all the great 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. One major risk of Luffy's powers is that he is vulnerable to attacks in the moments when his limbs are stretched to their limit, as Buggy and Kuro both demonstrated early on in the series. Luffy, however, has adapted his fighting style to minimize this risk such as when Buggy attempted to exploit this weakness of Luffy. Luffy, of course, also suffers the same weaknesses to water and Kairoseki similar to all other Devil Fruit users. However, he appears to forget about his weakness to water, as he always wants to try some type of sport in the sea and will dive into the ocean when he sees someone drowning (only to end up drowning himself).

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 a rather reckless manner, to attacking an enemy with a barrage of fast and strong punches. He has also developed several peculiar methods of combat as time passed, adapting new forms by manipulating his elastic body, most prominent his "Gear Second" and "Gear Third" forms, allowing him momentarily increase his strength in combat. After the time skip, he has learned to use Haki in conjunction with the fruit's powers, as well as having more control over his forms.

Attacks
Luffy always begins his attacks by saying "Gomu Gomu no..." and finish 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 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. In the FUNimation dub, the gun references are kept in.

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）)

The literal translation means 'Rubber Rubber Pistol'. This is his signature attack, while stretching his arm back he throws a devastating punch. The basis of this attack can be traced back to his childhood when he tells Shanks that his punch is "As powerful as a pistol!" 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. This is called Gum-Gum Pistol in the Viz Manga and FUNimation dub and Gum-Gum Blast in the 4Kids dub. 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 attempted by Luffy 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 doesn't 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. 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 (ゴムゴムの銃｢散弾｣（ピストル｢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. In the anime this is called Gomu Gomu no Pistol and Shotgun. In the Viz Manga, this is called Gum-Gum Pistol Shotgun, while in the 4Kids dub, it is called Gum-Gum Quake. This was first seen being used against Crocodile after Luffy wet his own body with water.


 * 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 of his arms or both and grabs a handhold, then retracts them, projecting himself high into the air at high speeds, over great distances, or even into an opponent. This technique is oftentimes 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 Shells Town in the manga. In the anime, it was first seen being used to crash into Alvida's crew. A humorous usage of this "attack" was accidentally against Ace and Smoker in a Restaurant, who are both Logia Users but didn't have the reflex to dodge the Rocket. This is called Gum-Gum Rocket in the Viz Manga and 4Kids and FUNimation dubs.


 * 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 either a double punch side-by-side, or an 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-black 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 and Gum-Gum Double Barrel in the 4Kids dub. According to a fan poll, this is the fifth favorite attack amongst fans with a total of 995 votes.


 * Gomu Gomu no Gatling (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 strong punches that creates the illusion of him having multiple arms, however he doesn't actually grow more arms so his arms can be caught by an opponent fast enough (as Enel and Rob Lucci 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), and Gum-Gum Rapid Fire in the 4Kids dub. 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 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 except the fight against Usopp, The Franky Brothers and in the fight against Blueno, this attack is always renamed "Gomu Gomu no Pistol".


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


 * Gomu Gomu no Rifle (ゴムゴムの回転弾（ライフル）): 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, putting a spin on them. This attack is called Gum-Gum Rifle in the Viz Manga and FUNimation dub and Gum-Gum Drill in One Piece 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.


 * 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 similar to Gomu Gomu no Gatling, but with none of the punches actually making contact with the target(s) at first, and finishes with a single double-fisted blow similar to Bazooka. A powerful technique that can pierce strong armor, and, in combination with Zoro's Three-Swords Style, devastating enough to puncture a hole through a massive tidal wave. This was first seen being used against one of the Franky Family's "Mighty Destroyers". In the Viz Manga and video game One Piece Grand Adventure, this is called Gum-Gum Cannon.

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 and 4Kids and FUNimation dubs.


 * Gomu Gomu no Tsuchi (ゴムゴムの槌): 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 Chou-Chou'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. 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 and FUNimation dubs.


 * 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 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 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 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) 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 front porch of the Baratie. This is called Gum-Gum Battle Axe in the Viz Manga and FUNimation dub and Gum-Gum Axe in the 4Kids dub.


 * Gomu Gomu no Ozuchi (ゴムゴムの大槌): Similar to Gomu Gomu 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 front porch. This is called Gum-Gum Giant Gavel in the Viz Manga and Gum-Gum Giant Hammer in the 4Kids and FUNimation dubs.

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 Fusen (ゴムゴムの風船): A technique wherein 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 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. It is named for the fact that if one were to hit another's head hard enough, they could make them hear bells. This was first seen being used to defeat Kuro. This is called Gum-Gum Bell in the Viz Manga and 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 Mohmoo and unwound, spinning the Sea King around rapidly to crush the Fishmen surrounding him. After spinning around several times, Luffy then let go of Mohmoo and threw him far away. While it took out most of Arlong's Fishmen, it however had the disadvantage of getting Luffy's feet stuck in the ground. 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 One Piece Grand Battle, and during his fight with Rob Lucci, where he doesn't plant his feet into the ground, but simply grabs his target and twisting his mid-section before unwinding, and throwing his opponent.


 * 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 4Kids and FUNimation dubs.


 * 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 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 finish off Mr. 3. In the Viz Manga, and FUNimation dub this is called Gum-Gum Stamp.
 * Gomu Gomu no Stamp Gatling (ゴムゴムのスタンプ銃乱打（ガトリング）): Similar to Gomu Gomu no Stamp, except he makes multiple strikes with his foot. This was first seen used at Marineford against the Three Admirals, crushing a mast frozen by Aokiji. In the Viz Manga and FUNimation subs, 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 is called Gum-Gum No Way! in the Viz Manga, 4kids and FUNimation dub. 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 Sensuikan (ゴムゴムの潜水艦): Similar to the Pistol, but his fist travels underground to uppercut the target. In the 4Kids and FUNimation dub, this is called Gum-Gum Submarine.


 * 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 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. In the Viz Manga, 4Kids dub, and the FUNimation 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）): An extremely powerful move and is easily one of Luffy's strongest attacks. Luffy first uses Gomu Gomu no Balloon and twist 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 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 Alabasta, and then propel him several hundred feet into the air. This technique can be used going sideways, upwards towards airborn targets, and downwards while Luffy is airborne. In the Viz Manga and 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. 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 and Gum-Gum Daze... in the FUNimation dub.


 * 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. 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 can't 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 Mantra ability user as they also can't 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 around a person's limbs in order to manipulate their movements. In the Viz Manga, this is called Gum-Gum Ally Robot. This was first used against a Marine in Enies Lobby.
 * Mikata Robo Punch (味方ロボパンチ): Luffy uses his "Ally Robot" to punch an opponent. In the Viz Manga, 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. In the Viz Manga, 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. In the Viz Manga, this is called Gum-Gum Volcano. This was first seen being used against marines at Enies Lobby.


 * 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. In the Viz Manga and FUNimation subs, this is called Gum-Gum Rain. It was first seen being used on gaolers of Impel Down.


 * 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. This was first seen used against Dracule Mihawk's Kokuto Yoru, with Buggy as the shield. Buggy isn't harmed due to his Devil Fruit ability, but it doesn't make him any happier about it. The Gear Second version of this attack was first seen before this normal version made its debut. In the Viz Manga and FUNimation subs, 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.

 * 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. In the FUNimation dub, this is called Gum-Gum Grab. 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 pushed Zoro off the Going Merry as Luffy reeled it back in.


 * 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. In the FUNimation dub, this technique is called Gum-Gum Suspension Bridge. 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): A technique wherein Luffy entwines himself around something, and then stretches his arm to grab an object. In the FUNimation dub, this is called Gum-Gum Lasso.

 * 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 Barbarbossa's ship in one of the Alabasta 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 Alabasta filler episode because Luffy went delusional from drinking cactus juice and thought that he was Crocodile. In the FUNimation dub, this is called Gum-Gum Submarine.


 * 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.

In the FUNimation dub, this is called Gum-Gum Bungee Jump.


 * Gomu Gomu no Tomozuna (ゴムゴムの艫綱): 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. This was first seen being used in Sanji's filler episode in the Post-Alabasta arc to get on and off a marine ship. In the FUNimation dub, this is called Gum-Gum Mooring Line.


 * 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 Fuusen during the Enies Lobby saga as Luffy uses it to escape the Marines by jumping down from a build in while still holding on the 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, 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.

In the FUNimation subs, 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 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 Dave 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 Kanpachino and Brindo.


 * Gomu Gomu no 100,000 Degree Bazooka (ゴムゴムの100,000ダグレーバズーカ): Basically a regular Gomu Gomu no Bazooka technique that was used by Luffy against Don Achino. The technique differs a little from a regular Bazooka technique, however at the moment of impact, Luffy continued applying force to the attack despite his hands being burned by the powers of Don Achino's Devil Fruit, the Atsu Atsu no Mi. As a result, Luffy was able practically use Achino's own Devil Fruit powers against him by allowing the heat being accumulated into his arms as he maintains contact with the Don's body to build-up. Thus allowing Luffy to send Achino flying away into his house, Lovely Land.


 * Gomu Gomu no Haragi (ゴムゴムのハラギ): Luffy uses Gomu Gomu no Fuusen and draws a face on his expanded belly and moves it while he dances. In the manga, this move was not named. In the FUNimation subs, this technique is called Gum-Gum Belly Talk. This joke technique was used in the Kuja's dinner celebration.


 * 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 subs, this technique is called Gum-Gum Ricochet.


 * Gomu Gomu no Scatter Chomp: An attack Luffy used in the One Piece x Toriko crossover special.

Forms
Throughout the series, Luffy is often faced with opponents that require unusual methods to defeat. For this reason, he sometimes adopts certain "forms" intended to enable him to defeat those enemies. However, some of these forms are simply cosmetic and don't involve his Devil Fruit powers in any way, such as Afro Luffy, giving him no actual physical advantages whatsoever. The most revolutionary and useful of these forms so far are the "Gear" forms, as described in the section below.

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

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 use his sand-morphing ability. 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 it's contents were in too much danger from Crocodile's attacks, Luffy later drains 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.


 * Mizu Mizu no Pistol (水水の銃（ピストル）): 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, this is called Water-Water Pistol.

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 (アフロルフィ) was born.

Usopp claims that the afro gives Luffy extra power. While donning the afro, Luffy also donned boxing shorts, boxing gloves, some type of straps on his feet, and had a temporary tattoo of a flaming skull and cross-bones on his chest. While wearing the afro, Luffy also tends to say things such as "Hell yeah!". Although only Nami and possibly Zoro think that it doesn't help anything, the others say "Because of the afro..." is how he gets more powerful (but they might be joking or just playing along).

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 Hook (ゴムフック): Luffy launches an elongated hook, which can hit the enemy’s back due to his stretching ability. In the Viz Manga and the video game One Piece Grand Adventure (dubbed by 4Kids), this move is called Gum Hook.


 * 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. In the Viz Manga and One Piece Grand Adventure, this is called Gum-Gum Flail.

Gear Second


Gear Second (ギア2（セカンド）) is a powerful form that was first seen in Luffy's fight against Blueno. Luffy pumps his blood rapidly with his legs to kick start the process which in turn, increases the speed of his blood flow, thus providing more oxygen and nutrients to various parts of his body which makes him much faster and stronger. It uses even more oxygen and energy, hence using up more food and he has to breathe harder. The increase in his metabolism causes him to be hungrier than usual or even a paralytic type effect after a long usage of it, like in the second fight with Rob Lucci, where Luffy was only able to lie on the floor. Lucci, one of the first of Luffy's opponents to witness it, compares the process to doping. Doping is adding more red blood cells to the body, which in turn allows for greater delivery of oxygen and nutrients to the body. In Luffy's case, his organs and blood vessels are made of rubber allowing them to expand and contract at greater amounts without tearing. Essentially Luffy increases the blood flow by forcing more blood through his blood vessels via his legs and thus increase his fighting ability. This mode's enhancements to Luffy's physiology gives him the ability to use a new, stronger set of techniques which are generally the same as his old ones, but are so fast that even a skilled assassin would have a hard time actually seeing them. This is called Gear Two in the Viz Manga, Second Gear in the Official Simulcast subs, and Gear Second in the FUNimation dub.



This form also enables Luffy access to his own version of the Rokushiki technique, Soru, which would make sense since he used Soru's principle, which is to kick the ground ten or more multiple times to propel the user over to a desired distance at imperceivable speeds, as the basis of Gear Second by incorporating it with his Gomu Gomu No Mi powers. In other words, Luffy practically uses his elastic body by compressing it and using it as the kick-off point when initiating Gear Second. As a result, he can not only utilize a much more refined form of Soru that is far superior to other Soru users, but the power of his attacks are also greatly enhanced by the great speed that they seem to break the sound barrier, generating sonic boom-like effects in the process. He has been able to heavily damage some of the strongest characters in the series in this form with only one attack, such as Magellan, Blackbeard, Shiki and Garp. In this form, his metabolism rate is so high that his sweat vaporizes rapidly giving rise to a steaming appearance, and, in the anime, his skin turns slightly pink and shiny from the increased blood flow. He also says almost all of his attacks in English as opposed to Japanese. Luffy also tends to take a certain pose right after activating Gear 2nd with one hand making a fist and touching the ground in front of him and the other one touching his knee, possibly to maintain the increased blood flow until the process has stabilized.

At first, 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 thus also mean reduced strength and ability after significant amounts of usage, as pointed out by Lucci when Luffy's attacks start losing their speedy edge because with all his nutrients running low, having a faster blood flow would be useless as there are no nutrients to use. Due to this, as also pointed out by Rob Lucci, Gear Second hacks away Luffy's life force dramatically, increasing a chance of having a much shorter life because he is starving his body, though Luffy rebutles, saying that it doesn't matter as long he saves his nakama. After Gear Second wears off, Luffy can recover quickly through replenishing of his nutrient storage by eating meat. Recently, Luffy has demonstrated more excessive use of his Gear second ability throughout the cause of the Impel Down arc without such exhausting costs like his fight with Rob Lucci, as well as being able to activate it at conveniently brief periods of time to save his stamina and strength reserves for more lasting durations. This is possibly because of Luffy's mastery over the form along with his desire to save Ace, and possibly the large amount of food he ate during the trip to Impel Down.

While not in the anime and manga, in the 7th movie of the series which takes place before the Water 7 arc, Luffy briefly and unknowingly activated Gear Second during his fight against Ratchet, the antagonist of the film, when the sheer pressure of the machine Luffy is forced to hold up unknowingly causes his legs to end up pumping his blood flow.

Often times, when using several attacks in succession, Luffy will omit the "Gomu Gomu no" prefix. 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 fist's 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 and powerful enough to propel the unlucky recepient several meters away. The incredible speed both makes the strike far more powerful, and harder to dodge. In the Viz Manga and FUNimation dub, this is called Gum-Gum Jet Pistol. This was first seen being used against Blueno.
 * After Time-Skip: Luffy has shown to be able to use this attack in conjunction with Busoshoku Haki, making it even more powerful, to completely destroy a Pacifista.


 * Gomu Gomu no Jet Stamp (ゴムゴムのＪＥＴスタンプ): Luffy delivers a Gomu Gomu no Stamp, with the same effect as the Jet Pistol. In the Viz Manga, this is called Gum-Gum Jet Stamp. 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. In the Viz Manga, FUNimation dub, and FUNimation subs, this is called Gum-Gum Jet Bazooka. This was first seen being used against Blueno. It was apparently powerful enough to break through Blueno's strongest Tekkai technique, Tekkai: Gou. During the battle against Moria in his Shadow's Asgard form, Luffy demonstrated being able to use this move to propel himself from mid-air, allowing him to perform this attack continuously.


 * 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. In the Viz Manga and FUNimation dub, this is called Gum-Gum Jet Whip. 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 with great force. When attacking head-on, the stretching 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. In the Viz Manga and FUNimation dub, this is called Gum-Gum Jet Bullet.


 * 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 simultaneously. Visually, the move only differs from his normal Gomu Gomu no Bazooka in that instead of doing an open palm strike, he has clenched fists which leave two knuckle shaped imprints on his foe. As since the move hit so fast, the air from it really looks like Luffy is literally firing two pistols. This was first seen being used against Rob Lucci and is one of the few moves unique to Gear Second (unless the anime-only regular "Gomu Gomu no Twin Pistol" is included). In the Viz Manga, this is called Gum-Gum Twin Jet Pistol.




 * Gomu Gomu no Jet Gatling (ゴムゴムのＪＥＴ銃乱打（ガトリング）): This is one of Luffy's strongest techniques. Luffy stands still, bends forward and moves his arms upwards at speeds which they can no longer be seen, leaving only jet streams in their place, very much like how the Jet Pistol looks. This results in an effect comparable to Foxy's Kyuubi Rush, except that Luffy doesn't need to make use of Noro Noro photons to slow down his target in order to accumulate the hits. The hits land so fast that, after a volley, they seemingly connect simultaneously. The circles of air bursts from the punches surrounding Luffy, resemble the many barrels of an actual Gatling gun. However, due to the large amount of energy it uses, Luffy cannot sustain it for long, although the time it is used is considerably longer than the regular Gatling. During his fight against the combined efforts of Marigold and Sandersonia, Luffy demonstrated an omnidirectional version of this move by falling on his back, then, while lying down, launches a rapid barrage of powerful high-speed punches from the ground, effectively nullifying both sister's attacks. In the Viz Manga and FUNimation dub, this is called Gum-Gum Jet Gatling.


 * Gomu Gomu no Jet Rocket (ゴムゴムのＪＥＴロケット): A Gear Second version of Luffy's Gomu Gomu no Rocket technique. After grabbing onto something with stretched out arms, Luffy instantly propels himself forward with blinding speed. This was first seen being used against Moriah. In the Viz Manga, this is called Gum-Gum Jet Rocket.


 * Gomu Gomu no Jet Migawari (ゴムゴムのＪＥＴ身代り): Somewhat of a gag move where Luffy stretches his arms to grab a person (an ally, an opponent, or otherwise a simple bystander) from afar then pulls them close to where he is to block an attack that Luffy would otherwise be incapable of surviving on his own. Using his Gear Second's speed, Luffy can capture himself a shield very quickly. He has a normal (non-Gear Second) variant of this move where Luffy sends the recipient spinning towards the assaulter to preoccupy them as he makes his escape. This was first seen being used by Luffy on Buggy, using the latter as a human shield against Mihawk. This is called Gum-Gum Human Shield Jet in the Viz Manga and Gum-Gum Jet Human Shield in the FUNimation subs.

After Time-Skip
After the time skip, it appears that Luffy has gained far greater control over this form as he was shown utilizing it in only parts not on his body but rather a set part or parts of it. How he does this is currently unknown. The advantage of using it in a set part of his body could be that it doesn't exhaust him as quick as he seemed to be not tired after using it in rapid succession. Luffy also now does not need to perform his usual stance to activate his Gear Second like two years ago. Because of that, he has demonstrated being able to enter Gear Second to perform incredible air-borne feats even while his upper body was restrained.


 * Gomu Gomu no Jet Hammer (ゴムゴムのJETハンマー): The Gear Second version of Gomu Gomu no Ozuchi, which was not used since Luffy's battle with Don Krieg. Luffy wraps his legs around his opponent and, at an extreme speed, smashes him into the ground. Unlike the normal version, Luffy doesn't twist, and then un-twist his legs during the execution of this technique. It was first used against Vander Decken IX while Luffy was tied up.

Anime Uses

 * Gomu Gomu no Jet Rifle (ゴムゴムのＪＥＴ回転弾（ライフル）): A Gear Second technique that first appeared in the anime. Luffy delivers a very fast Gomu Gomu no Rifle. The winding of the original Rifle along with its snapback happening almost at the same time as Luffy speeds towards the target makes this move impossible to evade. In the Viz Manga, this is called Gum-Gum Jet Rifle. This was first seen in the anime being used against Blueno.


 * Gomu Gomu no Jet Lance (ゴムゴムのＪＥＴランス): A Gear Second technique that first appeared in the anime, with the name of Gomu Gomu no Jet Yari (ゴムゴムのＪＥＴ槍), however time after, Luffy makes the same move with its official name. Luffy delivers a very fast Gomu Gomu no Yari that seems to connect instantly with his opponent. 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（アックス）): A Gear Second technique that first appeared in the anime. Luffy stretches his leg vertically and then crashes it down on his opponent, unlike the usual version however, rather than merely smashing his foot into the enemy the speed at which it is done is so quick that rather than attacking the area directly in front of him, his Jet axe strikes several metres in length, thus increasing its range. This was first seen in the anime being used against Lucci.

Gear Third


Gear Third (ギア3（サード）) is another powerful form that is first hinted at the climax of the fight between Luffy and Blueno, and first used, but not witnessed, 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 (or greater than) that of a giant's, if anything resembling Oars size. Used with his already-strong physiology, this apparently gives his arm more mass and a larger area to attack with far greater strength, but he sacrifices mobility for this strength, as his limbs are now so large that Luffy has extreme trouble moving unless he is in his Fuusen form. This is called Gear Three in the Viz Manga, Third Gear in the FUNimation subs, and Gear Third in the FUNimation dub.

Gear Third is generally used when raw physical strength is needed, the bones are the key difference between this form and his old "Gomu Gomu no Fusen" 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. Unlike the normal Gomu Gomu no Fusen technique, bullets ricochet off of Gear Third instead of bouncing off. 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. The downside is, the lag time in which it takes Luffy to transfer and re-channel the amount of air trapped inside his bones through his very being can be disadvantageous. Furthermore, it is quite difficult for Luffy to move while part of his anatomy has been converted to gigantic proportions, making the Gear inadvisable to use against opponents capable of moving at high speeds (like Lucci) or in an enclosed place as he is leaving himself vulnerable to attack, which is why since his battle against Rob Lucci, Luffy tends to only activate Gear Third against massive and often slow-moving targets whom he likes to assault with his Gear Third moves coming from high above in mid-air, where the said attacks could not be obstructed. 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, which is a negative side-effect for Luffy due to the massive expansion undergone prior to release. 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 little to no ability to stretch at all, and it has been shown that Luffy loses an incredible amount of strength when he kept hitting Lucci's face to no effect. The best strategy Luffy could use, while waiting for himself to return to normal, is to run and hide from an opponent for the duration of the shrinkage. Another strategy is only using Gear Third for a few seconds for only one move so his shrinkage is minimized. As with most Devil Fruit abilities, his clothes expand or contract as necessary. During the Whitebeard War, this drawback was not shown during every use, perhaps being glossed over by the many different battles taking place all at once; the anime includes the drawback.

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


 * Hone Fusen (骨風船): Luffy inflates his body by blowing air into his bones. This is done by biting into his right thumb, presumably cutting it open down into to the bone, and then blowing air directly into the opened bone. This technique seems to give Luffy a sturdier defense than the regular balloon, since bullets now ricochet off of him instead of bouncing off of him. Due to this form having a disadvantage of moving about, he can transfer his air into his torso, and then launching himself with his "Gomu Gomu no Rocket" technique. This was first fully shown in Luffy's battle against Rob Lucci. In the Viz Manga, this is called Bone Balloon.


 * 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 extreme force due to the larger size of his fist. This was first fully seen being used against Rob Lucci. Its sheer power was able to fling him from the Bridge of Hesitation on to a Buster Call Battleship. In the Viz Manga, FUNimation dub, and FUNimation subs, this is called Gum-Gum Giant Pistol.


 * Gomu Gomu no Rocket (ゴムゴムのロケット): A Gear Third version of Luffy's normal Gomu Gomu no Rocket. While using this move, Luffy's chest bones are inflated, and bullets ricochet off his body. This is not explicitly name as a "Gigant" move. This was first seen being used to propel Luffy onto a Buster Call battleship in pursuit of Rob Lucci.


 * Gomu Gomu no Gigant Axe (ゴムゴムの巨人の斧（ギガント･アックス）): A Gomu Gomu no Ono with even more power due to his enlarged foot and leg. This was first seen being used against Rob Lucci. Its sheer power is able to damage and create a hole in the deck of a Buster Call Battleship. In the Viz Manga, this is called Gum-Gum Giant Axe.


 * 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. Its sheer power is able to damage the mast of a Buster Call Battleship. In the Viz Manga, this is called Gum-Gum Giant Whip.


 * Gomu Gomu no Gigant Bazooka (ゴムゴムの巨人のバズーカ): A Gear Third version of Luffy's Gomu Gomu no Bazooka attack. To create this attack, Luffy inflates both his arms by biting both his thumbs and blowing into them. With both his arms inflated to large proportions, Luffy then delivers the attack onto an opponent the same way he regularly does with a normal Gomu Gomu no Bazooka attack, except with much greater power. This was first seen being used against Oars to break his spine. In the Viz Manga, this is called Gum-Gum Giant Bazooka.




 * Gomu Gomu no Gigant Jet Shell (ゴムゴムの巨人のＪＥＴ砲弾（ギガント・ジェットシェル）): One of the strongest techniques Luffy had. While he is still in Gear Second, Luffy goes into Gear Third with Hone Fuusen. With the combination of Gear Second's high speed and Gear Third's air within his bones, Luffy launches his air filled body and rams onto an opponent like a large cannonball. This move is quite reckless, as Luffy suffers both from the excess burn on his body from Gear Second, and the difficulty of moving his body from Gear Third. This was first seen being used against Gekko Moriah while he is in his Shadow's Asgard form. In the Viz Manga, this is called Gum-Gum Giant Jet Shell.


 * Gomu Gomu no Gigant Rifle (ゴムゴムの巨人回転弾（ギガント･ライフル）): Luffy activates Gear Third to expand one of his arms and then use it to launch a giant version of the original Gomu Gomu No Rifle at a target with greater power, drilling hard into the unfortunate target. This attack is strong enough to destroy the heavily-armored Pacifista, and was first seen being used to defeat PX-4 on the Sabaody Archipelago. The fist produced in this attack is approximately the same size as the entire body of the giant Vice Admiral Luffy uses it to defeat. In the Viz Manga and FUNimation subs, this is called Gum-Gum Giant Rifle.


 * Gomu Gomu no Gigant Stamp (ゴムゴムの巨人のスタンプ): Luffy activates Gear Third and expands his foot to deliver a giant version of Gomu Gomu no Stamp with greater force. Incidentally, this was first used in conjunction with Mr. 3's Giant Candle Wall to push it back. This was first seen being used against Magellan in Impel Down. In the Viz Manga and FUNimation subs, this is called Gum-Gum Giant Stamp.


 * Gomu Gomu no Gigant Fusen (ゴムゴムの巨人の風船): Luffy activates Gear Third and expands his torso to create a giant version of his traditional Gomu Gomu no Fuusen, with a much sturdier defense. This move was strong enough to cushion the impact from a massive adversary and was first used to protect Ace and Mr. 3 from a punch of Sengoku in his giant form. In the Viz Manga and FUNimation subs, this is called Gum-Gum Giant Balloon.

After Timeskip
After the time skip, as with Gear Second, Luffy seems to have obtained better skill at utilizing Gear Third. Previously, Gear Third would increase the size of the majority of Luffy's arm, thus reducing the speed of the attack in exchange for a powerful impact. However Luffy after two years can seemingly control where the air is allowed to "sit" within his limbs, where his fist becomes large and instead of the air being equally distributed throughout his arm, an equivalently large mass forms behind the fist. This allows a majority of Luffy's arm to remain as it is, allowing him to stretch it, thus allowing him to attack much faster than pre-time skip. He was seen being able to enlarge his right fist while inside a Yarukiman bubble (where there is limited air supply) rapidly upon engaging against the Kraken, demonstrating the use of infusing Busoshoku Haki into his colossal-sized arm to enforce its durability and defeat the sea monster. It also appears that after using Gear Third, Luffy doesn't suffer any side effect as he did before he turns into his chibi form. It's still unknown whether this is due to his new found control over Gear Third or the fact that he imbued Haki to it.


 * Gomu Gomu no Elephant Gun (ゴムゴムの象銃（エレファント・ガン）): After activating Gear Third, Luffy will also implement Busoshoku: Koka into his attack, turning his arm black by instantly vulcanizing it. Just like his Gomu Gomu no Pistol, Luffy launches his attack at his enemy with great destructive power. However, the Gear Third's air only fills the end of his arm, giving him a giant fist with an elephantine round wrist. It is named after an elephant gun, a large caliber firearm used to hunt elephants that used black powder at first and then started using smokeless powder. This attack was first seen underwater against the Kraken. After this attack, Luffy appeared to remain the same size. The reason for this is so far unknown.

Video Game Only

 * Gomu Gomu no Gigant Gatling (ゴムゴムの巨人の銃乱打（ガトリング）): Luffy activates Gear Third and expands both his fists to deliver a giant version of his powerful Gomu Gomu no Gatling technique. This technique is completely exclusive in the fighting game, Jump Ultimate Stars (using Luffy's strongest battle set) and does not appear in either the manga or in the anime, as it would not normally be usable in normal circumstances due to the extremely large masses the technique involves, which normally inhibits Luffy's speed.

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 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.

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): 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 dub.


 * 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 Fire Works, but with the Golden Ball attached to his arm. This technique was used against Enel's Raigoh. 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. This is called Gum-Gum Fireworks: Golden Peony in the Viz Manga and FUNimation dub. According to Oda in a response to a fan in a SBS, Luffy himself didn't 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.


 * Gomu Gomu no Ogon Rifle (ゴムゴムの黄金回転弾（ライフル）): 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 Raigoh with the Golden Ball, Luffy used this technique to defeat Enel and ring the Golden Bell of Shandora. 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. According to a fan poll, this is the thirteenth most favorite attack amongst fans with a total of 327 votes.




 * Gomu Gomu no Gigant Thor Axe (ゴムゴムの巨人の雷斧（ギガント・トール・アックス）): A Gear Third move performed when Luffy enlarges his leg and thrusts it high into a low-lying thundercloud. When he brings it down, the charged limb unleashes a massive shock wave, powerful enough to cause the ground underneath to crumble. This was first seen used to defeat Shiki, and was only possible thanks to the storm that they were fighting in. The attack was named after Thor, the Norse god of thunderstorms, who wielded a hammer rather than an axe. It is also said that every time Thor hit with his hammer, a lightningbolt would be brought from the skies, not always hitting the opponent, but usually just for demonstrating its powers. The kanji for this attack, "Kyojin no Rai Ono", means "Lightning Axe of the Giant".

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:


 * Armée de L'Air Gomu Shoot (空軍（アルメ・ド・レール） ゴムシュート): 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. This was first seen being used against Wapol. This is called Armée de L'air Air Assault in the Viz Manga, Taffy Trouncer in the 4Kids dub, and Armée de L'Air Assault Gum Shoot in the FUNimation dub.


 * Gomu Gomu no Tatsu Épaule Muchi Maki Shoot (ゴムゴムの龍 肩肉 巻き ムチ シュート): A combo attack of Luffy, Zoro and Sanji to kill a Sandora Lizard in the desert of Alabasta. It's a combination of Luffy's Gomu Gomu no Muchi, Zoro's Tatsumaki, and Sanji's Epaule Shoot. For this attack however, he uses his arm for the Gomu Gomu no Muchi instead of his leg. This is called Gum-Gum Dragon Epaule Twister Whip Sprawl in the Viz Manga and Gum-Gum Tatsu Epaule Maki Whip Shoot in the FUNimation dub.


 * Gomu Gomu no Sanbyaku Pound Cannon (ゴムゴムの三百煩悩（ポンド）攻城砲（キャノン）): A combo attack between Luffy and Zoro. Luffy and Zoro use the Gomu Gomu no Cannon and the 108 Pound Hou at the same time. This is actually a 216 Pound Cannon, but Luffy decided that name was too long and hard to pronounce. Zoro expressed amused indifference and accepted the new name for the attack. This was first used against a huge wave during the Aqua Laguna to let the Rocket Man pass.


 * 600,000,000 Beli Jackpot (６億Ｂ・ＪＡＣＫＰＯＴ（6おくベル・ジャックポット）): This attack was a huge collaborative effort between Luffy, Zoro, Sanji, Robin and Franky in an all-out, multi-directional assault against a horde of zombies. Luffy provides his trademark punches to the assault. This was first seen being used against a group of Zombies. The name is derived from The Straw Hats' combined bounties.


 * Santoryu Gomu Gomu no Diable Mouton Jet Roppyaku Pound Cannon (三刀流ゴムゴムの悪魔風羊肉JET六百煩悩攻城砲): A combo attack performed by all three top fighting members of the Straw Hat Crew: Zoro, Luffy and Sanji. Zoro performs a 108 Pound Hō, while Sanji activates his Diable Jambe technique and delivers a Mouton Shoot, then Luffy uses Gear Second and fires a Gomu Gomu no Jet Cannon. The impact of the three techniques hits a single target simultaneously. This was first seen being used against PX-4. In the FUNimation subs, this is called Santoryu Gum-Gum Diable Mouton Jet 600-Caliber Phoenix.


 * Gomu Gomu no Tonkachi Rifle (ゴムゴムのトンカチ･回転弾（ライフル）): A combo attack between Luffy and Mr. 3. Mr. 3 uses his Candle Lock technique on Luffy's hand to begin, whereupon Luffy stretches and twists his arm back before delivering a powerful blow aided by the hard wax. This was first used as the finishing blow to Minotaurus on Level 3 of Impel Down. Due to the extreme heat of the place, the Candle Lock only lasted for a very brief period of time, and the hammer melted as soon as the blow was dealt. This is called Gum-Gum Hammer Rifle in the Viz Manga and Gum-Gum Mallet Rifle in the FUNimation subs.


 * Gomu Gomu no Champion Rifle (ゴムゴムのチャンピオン･回転弾（ライフル）): A technique in which Luffy does a regular rifle technique, aided by Mr. 3's wax. To avoid making contact with Magellan's poisonous skin, Luffy had Mr. 3 encase his arms and legs in a wax armor, allowing him to hit Magellan without worry of harming himself. In the Viz Manga and FUNimation subs, this is called Gum-Gum Champion Rifle.


 * Gomu Gomu no Champion Bazooka (ゴムゴムのチャンピオン･バズーカ): An anime only technique in which Luffy uses his regular bazooka attack, but aided by Mr. 3's wax to prevent him from being poisoned by Magellan. In the FUNimation subs this is called Gum-Gum Champion Bazooka.


 * Gomu Gomu no Champion Gatling (ゴムゴムのチャンピオン･銃乱打（ガトリング）): An anime only technique in which the settings are the same as the Champion Bazooka; Luffy with his arms encased in wax is able to attack Magellan with a gatling technique without being poisoned. In the FUNimation subs, this is called Gum-Gum Champion Gatling.


 * Gomu Gomu no Kaiten Ono (ゴムゴムの回転斧): An anime only technique, a combination of moves executed by Luffy, Zoro, Sanji, and Usopp. Luffy executes Gomu Gomu no Fusen as well as twisting his body, using the stored air to launch himself into the air. Then, Usopp aboard the Merry-Go fires a cannonball at Sanji, while Luffy shoots both of his arms towards the target. Sanji at this point Armeé de L'air Hana Shoots the cannonball at Zoro who executes 108 Pound Ho to fire the cannonball up into the air and toward Luffy. Luffy catches the ball with his feet, the inertia of the cannonball spinning him vertically several times causing his legs to twist with each revolution. After all of the cannonball'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 since Zoro and Sanji has to stop him after cutting his target. This was first used to destroy Ratchet's castle in the seventh One Piece movie.


 * Kamehame Gomu Gomu no Bazoo'ha (かめはめゴムゴムのバズー波): A combo attack that Luffy and Goku invented together to use against Buggy and Emperor Pilaf's Tettiri No. 55, during the One Piece/Dragon Ball crossover comic special, Cross Epoch. This is a simultaneous attack of Luffy's "Gomu Gomu no Bazooka" and Goku's "Kamehameha Wave". The name of this technique is a combination of their individual attack names. In the Viz Manga, this is called Kamehame Gum-Gum Bazooha.


 * Gomu Gomu no Kamehameha (ゴムゴムのかめはめ波): This is a special combo maneuver that Luffy invents with Goku during the One Piece/Dragon Ball Special. The pair create a 360o "Kamehameha Wave" attack as Luffy swings Goku round and round to help him blast the surrounding Enel horde.


 * Gomu Gomu no Ora Ora (ゴムゴムのオラオラ): Only present in the game Jump Super Stars, Luffy teams up with Jotaro Kujo from JoJo's Bizarre Adventure with Luffy attacking with his Gomu Gomu no Mi and Jotaro attacking with his Stand, Star Platinum.


 * Gomu Gomu no Kugi Punch (ゴムゴムのくぎパンチ): A combo attack that Luffy and Toriko invented together to use against the Knock-Out Koala that resided on Hangerilla Island. Stretching his limbs around the roots of the Multitude Fruit Tree, Luffy acts as a sling for Toriko to launch himself at the koala, so his San Ren Kugi Punch's power is increased.

Early One Piece
Luffy's stretching powers were a result of Oda's desire for the fighting style to be silly, so that no matter how tense a situation got, the reader could relax without becoming stressed out. Oda originally just called the fruit the 'Gomu Fruit'. But his editor pointed out there really existed a Rubber fruit so Oda changed the name.

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.

Translation and Dub Issues
Viz, 4Kids and FUNimation all translate this fruit's name as the "Gum-Gum Fruit". This translation comes from the etymology of the Japanese word "Gomu". "Gomu" is a loan word from English, it comes from "Gum" which is used in English to refer to rubber to identify it as "Natural Rubber" instead of "Synthetic Rubber". This is not only true of Japanese, but most worldly language derive their word for "Rubber" from "Gum". For example, in Spanish: Goma, French: Gomme, German: Gummi, Albanian: Gomë, Croatian: Guma, Italian: Gomma, Finnish: Kumi, Norwegian: Gummi and so forth.

Viz most likely selected "Gum-Gum" as a translation over "Rubber Rubber" due to "Gum" being phonically similar to "Gomu". The only English version of the series to ever translate it out as the "Rubber Rubber Fruit" is the Odex version. This is because it has no connections to the North American versions at all. Despite translating Gomu as "Gum", all English versions refer to Luffy as a "Rubberman".

Trivia

 * In the 3rd Movie, it is shown that Luffy won't sink in water in his Gomu Gomu no Fuusen technique. However, this is not seen in the anime nor in the manga.
 * Luffy has more named Devil Fruit attacks than any Devil Fruit user.
 * After the time-skip, Luffy can activate his Gear Second without doing his "Blood-Pumping" pose. He can now pump his blood while standing, and even select a particular part of his body to bestow the effect upon; this ability to centralize the effects of Gear Second to any part of his body is not unlike that of those exhibited by skilled Zoan users, who are able to transform only a designated body part into animal form.
 * It appears that Luffy no longer reverts to his chibi form after using Gear Third. This was first shown after he defeated the Kraken. However this happened as well during his fight with Magellan, which was later added in the anime.
