Luffy fires out his arm and punches his enemy. He developed this attack because he wanted to have a punch as strong as a bullet fired from a pistol. The kanji for “pistol” is ‘juu’ meaning gun. Important note: Oda has a habit of writing kanji for attacks, but they are pronounced in other languages. Sometimes they end up being puns or jokes. In 2005, this was selected as the 9th most popular attack in the first One Piece 'Your Favorite Techniques' vote with 552 votes.

In 2005, this was selected as the 17th most popular attack in the first One Piece 'Your Favorite Techniques' vote with 162 votes.
Gomu Gomu no Kama	Gomu Gomu Sickle	Buggy	Vol.3 pg15.	Luffy stretches his hand horizontally across that which he wants to 'cut', then launches his body forward, 'cutting' his target in half with his arm.

Luffy pulls his hands far behind his back, then launches both of them forward simultaneously wrist to wrist hitting his foe very hard and usually sending them far, far away. In 2005, this was selected as the 5th most popular attack in the first One Piece 'Your Favorite Techniques' vote with 995 votes.
Gomu Gomu no Gatoringu	Gomu Gomu Gatling Gun	Kuro Neko Pirates, Krieg, Arlong, Sir Crocodile, Surprising Ball, Ener, Foxy, Usopp, Lucci, Marines, Blueno, Moria	Vol.4 pg81. Vol.8 pg54. Vol.10 pg166.

A barrage of straight punches that are so fast, Luffy appears to be riddling his opponents with Gatling Gun fire. The kanji means literally “Battering Gun” but may be interpreted as “Gatling Gun”. In 2005, this was selected as the most popular attack in the first One Piece 'Your Favorite Techniques' vote with 3785 votes.
Gomu Gomu no Yari	Gomu Gomu Spear	Captain Kuro, Arlong, Ener, World Government Agent	Vol.5 pg23 Vol.11 pg34. Vol.30 pg91. Vol.40 pg77.	Putting the soles of his feet together, Luffy launches them directly at his target like a lance.
Gomu Gomu no Kane	Gomu Gomu Bell	Captain Kuro, Arlong	Vol.5 pg89. Vol.10 pg165.	Luffy grabs hold of his opponent immobilizing them and stretches his neck far back only to whip it forward, planting it in his opponent's face.
Gomu Gomu no Oogama	Gomu Gomu Scythe	Krieg Pirates	Vol.6 pg175.	While in mid-air Luffy stretches both of his arms out to his side and can clothesline at least eight grown men. Works best combined with Gomu Gomu Rocket.
Gomu Gomu no Ono	Gomu Gomu Axe	Krieg Pirates, Arlong, Sir Crocodile, Ener	Vol.7 pg118. Vol.11 pg60. Vol.20 pg23. Vol.30 pg98.	After stretching his right leg high into the air, Luffy brings down his leg with tremendous force on top of his target. The kanji reads “War Axe”
Gomu Gomu no Buretto	Gomu Gomu Bullet	Krieg, Arlong, Wapol, Crocodile, Ao Kiji, Usopp, Blueno	Vol.8 pg18, pg56 Vol.10 pg166. Vol.16 pg96, pg186. Vol.22 pg195. Vol.34 pg80. Vol.35 pg116. Vol.37 pg32. Vol.40 pg198.	Luffy puts all of his body weight and strength into his right fist for a POWERFUL punch typically to his opponent's gut. The kanji used in this attack name indicate that it is a bullet fired from a rifle. In 2005, this move tied with Zoro's Bleeding the Wolf as the 28th most popular attack in the first One Piece 'Your Favorite Techniques' vote with 68 votes.
Gomu Gomu no Oozduchi	Gomu Gomu Giant Mallet	Krieg	Vol.8 pg74	Basically the same idea as the Gomu Gomu Mallet, but carried out with Luffy’s legs instead of his arms.
Gomu Gomu no Kazaguruma	Gomu Gomu Windmill	Moomu, Arlong Gang	Vol.10 pg22.	Luffy grabs hold of his target and twirls it in a circle at high speeds then releases it. Depending on the size of his target, this may also create a tornado-like effect that will sweep up anyone inside his swinging range. It is likely that seeing the pinwheel attached to Gen's hat in Cocoyashi village gave Luffy the idea for this attack.
Gomu Gomu no Tate	Gomu Gomu Shield	Arlong	Vol.11 pg29.	Stretching out his fingers across his face or body, Luffy makes a flexible shield.
Gomu Gomu no Ami	Gomu Gomu Net	Arlong, Sir Crocodile	Vol.11 pg33. Vol.20 pg34.	Shooting out his fingers and weaving them together, Luffy creates a net to capture his target in.
Gomu Gomu no Ikebana	Gomu Gomu Ikebana	Laboon	Vol.12 pg105.	Using his own ship’s mast, Luffy plunged it into Laboon’s face like a part of an ikebana arrangement. Ikebana is a term for traditional Japanese flower arragement. This was a gag technique.
Gomu Gomu no Tonkachi	Gomu Gomu Hammer	Candle Set, Candle Lock, Mr. 3	Vol.14 pg123.	Using Mr. 3‘s skills against him, Luffy fires his arm covered in the Officer Agent’s ‘Candle Lock’ at him. It is strong enough to break through 3’s ‘Candle Wall’.
Gomu Gomu no Sutanpu	Gomu Gomu Stamp	Candle Champion, Mr. 3, Sir Crocodile, Wiper, Blueno, Blueno, Moria	Vol.14 pg156, pg182. Vol.20 pg.20 Vol.28 pg99. Vol.40 pg208. Vol.44 pg41. Vol.48 pg75	A powerful kick from the sole of Luffy’s foot.
Gomu Gomu no Bo-gan	Gomu Gomu Bow Gun	Wapol	Vol.17 pg120.	Luffy coils himself tightly around his opponent, then releases them, sending them flying into the air as if shot from a bow gun.
Gomu Gomu no Dame Da!!	Gomu Gomu No Way!	Usopp	Vol.19 pg9.	Luffy defends his last water ration in the desert from Usopp by swinging it around. This was a gag technique. In 2005, this was selected as the 24th most popular attack in the first One Piece 'Your Favorite Techniques' vote with 76 votes
Gomu Gomu no Baku Baku	Gomu Gomu Chomp Chomp	Sir Crocodile	Vol.20 pg39.	Taking a cue from Wapol, Luffy expands his mouth and tries to catch his opponent by eating them.
Gomu Gomu no Marunokogiri	Gomu Gomu Buzz Saw	Sir Crocodile	Vol.22 pg82.	Luffy grabs onto his opponent from afar by stretching his hands out in front of him. He then curls his body into a ball and rotates at an incredible rate. Finally he pulls himself towards his enemy colliding with like a buzz saw chewing into a piece of wood.
Gomu Gomu no Pisutoru Shotto	Gomu Gomu Pistol Shotgun	Sir Crocodile	Vol.22 pg114.	This begins like Gomu Gomu Pistol, but Luffy twangs his rubber arm before it impacts with its target creating a single barrage of punches in one hit. It is difficult to translate this attack, normally I would just call it Gomu Gomu Shotgun, but Luffy specifically says “Pistol” before “Shotto” which is Japanese for ‘shotgun’. The kanji reads “Scatter Shot”. In conclusion, I’m not sure if Oda intends it to be ‘scatter shot’ or ‘shotgun’, but shotgun sounds cooler.
Mizu Mizu no Pisutoru	Water Water Pistol	Sir Crocodile	Vol.22 pg114.	After filling himself with water, Luffy shoots it out of his mouth in bubbles.
Gomu Gomu no Suto-mu	Gomu Gomu Storm	Sir Crocodile, Ao Kiji, Marines, World Government Agents	Vol.23 pg81. Vol.34 pg99. Vol.40 pg22.	Luffy fills himself with air then twists his body and facing the ground, releases the air at once sending him spinning into the sky. As he spins he performs a punching attack similar to Gomu Gomu Gatling but far more intense and from a greater distance. This is one of Luffy's strongest basic attacks and is effective against large groups or a single powerful individual. In 2005, this was selected as the 7th most popular attack in the first One Piece 'Your Favorite Techniques' vote with 815 votes
Gomu Gomu no Hanabi	Gomu Gomu Fireworks	White Berets	Vol.26 pg113.	After spinning in mid-air, Luffy explodes into a display of kicking feet and punching hands. In 2005, this was selected as the 19th most popular attack in the first One Piece 'Your Favorite Techniques' vote with 111 votes.
Gomu Gomu no "Bo~"	Gomu Gomu "Gu~h"	Ener	Vol.30 pg119.	By emptying his mind (hence the "Gu~h") Luffy is able to hide his movements from someone who can sense Mantra. The drawback is that since he cannot think, he cannot attack and may only dodge attacks instinctively. In Japanese when someone spaces out it's called 'bo~ tto suru'. In 2005, this was selected as the 20th most popular attack in the first One Piece 'Your Favorite Techniques' vote with 95 votes
Gomu Gomu no Tako	Gomu Gomu Octopus	Ener	Vol.30 pg120.	This is the second move Luffy creates in an attempt to counteract Mantra sensers. Luffy allows his body to go limp making his appendages seem like octopus tentacles.
Gomu Gomu no Tako Hanabi	Gomu Gomu Octopus Fireworks	Ener	Vol.30 pg121.	Luffy sends out a fury of punches and kicks from a mid-air position in no particular direction. Since he is acting, and therefore 'thinking' about doing something, that movement may be read by a Mantra seer. HOWEVER, with his body limp, if his blows bounce off of an object, he cannot control where the rebounded barrage of punches and kicks end up, much to the dismay of someone trying to read his actions.
Gomu Gomu no Raifuru	Gomu Gomu Rifle	Ener, Blueno, Lucci	Vol.30 pg125. Vol.40 pg118. Vol.44 pg38.	Luffy winds up his fist and pounds it into an opponent much like the Gomu Gomu Pistol. The kanji directly tranlates to "revolving shot". Since the Japanese word for rifle is "raifuru" the double meaning here is, I suppose, that modern rifles put a lengthy spin on the bullets fired from them. In this sense, Luffy is firing his "bullet" from a rifle as opposed to a shotgun or pistol as in other techniques he displays. In 2005, this was selected as the 21st most popular attack in the first One Piece 'Your Favorite Techniques' vote with 85 votes
Gomu Gomu no Hanabi-Ougon Botan	Gomu Gomu Fireworks-Golden Tree Peony	Ener	Vol.32 pg40.	With a giant gold sphere sealed around his right hand, Luffy swings the orb in all directions within a massive electrical field in an attempt to conduct a huge amount of electrical current to his rubber body which acts as a ground.
Gomu Gomu no Ougon Raifuru	Gomu Gomu Golden Rifle	Ener	Vol.32 pg58	With a giant golden sphere attached to his arm, Luffy winds up his fist and delivers a devasting blow just as with Gomu Gomu Rifle but combined with the fantastic weight of the massive orb. In 2005, this was selected as the 13th most popular attack in the first One Piece 'Your Favorite Techniques' vote with 327 votes.
Gomu Hukku	Gomu Hook	Foxy	Vol.33 pg191	Luffy delivers a painful hook to his opponent from behind.
Gomu Gomu no Fureiru	Gomu Gomu Flail	Foxy	Vol.34 pg25.	Luffy twirls his arm like a flail while wearing a boxing glove and stops his fist from flying at maximum speed by landing it on his opponent's face. The kanji for this is literally read as "Linked Hammer"
Gomu Gomu no Kyanon	Gomu Gomu Cannon	Franky Family Mighty Destroyer	Vol.35 pg53	Through a non-connecting Gomu Gomu Gatling-like series of punches, Luffy gather a tremendous force behind his fists which he unleashes similarly to Gomu Gomu Bazooka. Think of it as a concentrated Gomu Gomu Gatling. The impact of this move is supposedly greater than that of a battleship cannon. The kanji for 'cannon' are literally read as "Siege Cannon". This is indicative of the 'portable' nature of the attack not to mention Luffy does indeed use it for the first time during a siege. One will find this term used for medieval shoulder-mounted cannons that may be carried by troops.
Gomu Gomu no Mikata Robo	Gomu Gomu Robot Friend	A Marine	Vol.39 pg190	Twisting his arms and legs around an enemy's said appendages, Luffy moves the victim at will creating a walking shield/warrior. Kinda like a robot pal.
Mikata Robo Panchi	Robot Friend Punch	Marines	Vol.39 pg190	By controlling an opponent's movements via Gomu Gomu Robot Friend, Luffy uses his 'friend' to punch his/her own fellow warriors.
Mikata Robo Kikku	Robot Friend Kick	Marines	Vol.39 pg190	By controlling an opponent's movements via Gomu Gomu Robot Friend, Luffy uses his 'friend' to kick his/her own fellow warriors.
Gomu Gomu no Kazan	Gomu Gomu Volcano	Marines, World Government Agents	Vol.40 pg42	Definitely an attack used for striking a large group of foes. Similar to starting his Gomu Gomu Axe, Luffy launches his foot into the air and completely blows the roof off of a building. This act resembles an exploding volcano. To further the effect (and the damage) Luffy can push down the shattered wreckage of the building onto any opponents below via Gomu Gomu Gatling, in mid-air no less, where Luffy creates a rain of stone and mortar that will devastate any normal human foes below, similar to an explosion from a volcano.

Gears

This section contains spoilers regarding attacks that Luffy learns far into the story. If you do not wish to learn about them please proceed to Officially Listed Battles Fought to continue reading. The further Luffy traveled along the Grand Line, the more he came to realize that in order to protect his comrades and continue their grand adventure, he would have to come up with a drastically new form of using his Devil Fruit powers. Suffering a terrible defeat at the hands of a Marines Vice Admiral, Luffy was determined to find a, 'new way' to fight and he found it in the form of the Gears. It is not fair to make a judgement of exactly when he conceived of them as it is unclear whether or not he attempted to try using them before we (the readers) see him use them against a villain for the first time. However, it is clear he only thought of them after his defeat by the Marine Vice Admiral.

So what are the Gears exactly? They're simply Luffy using his powers beyond their obvious use. The main villain from the Arabasta arc noted that he 'honed his powers' to their greatest extent and although Luffy showed signs of doing the same shortly thereafter, the concept slowly faded away...until Chapter 387 where author Eiichiro Oda finally dropped a bomb on readers showing Luffy using what could best simply be described as a "power-up" in the form of Gear 2nd. Since that time Luffy has shown the ability to perform yet another power-up known as Gear 3rd. Whether or not he will refine these power-ups or create more remains to be seen. They are the prime example of Luffy's creative and sometimes scary grasp of biological needs/processes as related to his own body in combat. That or dumb luck.

Gear 2nd

The first of Luffy's power-up abilities in the series, this goes beyond standard 'power-ups' of the action/adventure manga genre which are gained only after weeks or years of brutal training. In this case, Luffy actually applied some comic book logic to his rubber body and further 'honed' his abilities as a Devil's Fruit user. Luffy squats and rests both hands on his knees which he proceeds to squish down to his feet and then release. Moments later Luffy's body begins to involuntarily twitch followed by steam pouring out from all parts of his body as he squats hunched over with his right hand clenched in a fist on the ground and his left hand on his knee. So what exactly is Luffy doing? First one must consider that Luffy's entire body is rubber, inside and out. When Luffy squishes his knees down and then releases them this acts as a pump shooting blood through his body. Since his heart and veins are rubber, they can take the extreme force without exploding. So what good does this do? Although much fan speculation has tried to apply logic to this, it's best described by a character who figures out the secret for himself. Luffy is performing a 'doping' of sorts, the increased blood-flow allows him to move at a tremendous speed, so fast that he seems to warp. Luffy learned this movement by watching users of the Six Forms techniques, specifically their move Soru where they kick the ground 10 times in an instant to dodge or move at impossible speeds. As Luffy has not named this particular movement, I will follow in suit by leaving it nameless specifically for him. However, Luffy's movement in Gear 2nd is actually not the main advantage of this power-up, far from it.

While in Gear 2nd, his normally quick attacks are all leveled up in speed and supposedly in strength as well; so much so that he appears to break the sound barrier each time he unleashes an attack with a sonic boom-like effect. This speed is the heart of Gear 2nd which came at a time when the opponents he was facing were remarkably quick as a result of their intense martial arts training. So what's with the steam? Luffy's body is evidently so far into overdrive that when he perspires, the sweat instantly evaporates causing the steam effect. Although there has been some speculation as to the physiological source of the power-up, the manga has gracefully stayed away from such a topic and we may be satisfied with the fact that if author Eiichiro Oda says it is so, it is. In the manga, steam is the signature characteristic of Gear 2nd. Occassionally Oda will draw Luffy with shaded eyes in the form but this is not always so and may simply be to express Luffy's determination. The animated version of One Piece shows Gear 2nd Luffy with a shiny pink hue to his skin and a husky voice. Although it would seem preposterous that Oda was not consulted on these decisions, he has made no effort to show such characteristics in the comic either via toning, shading or altered font.

Every power-up must have its weakness because then it wouldn't be a comic book power-up. Gear 2nd currently has two disadvantages, one is that Luffy cannot 'aim' accurately in this form when attacking. For his signature Gomu Gomu Pistol attack he must use his left hand to aim for his opponent, even if they are stationary, using his hand as a cross-hair of sorts before attacking. Luckily he has not shown any need to aim yet for attacks that are kick-related or use both hands, nor has Oda made this a debilitating handicap, at least not yet. This a bit hard to swallow since we're supposed to believe he can think and process information fast and accurately enough to appear to warp, but can't follow a target. The far more troublesome side-effect of Gear 2nd is that even though Luffy's body is rubber and his veins or heart won't explode, he's still a human. His heart in overdrive for a long period of time is simply 'too tiring', as stated in the comic, and he does not yet have the stamina to hold the form for long. Speaking of which, it remains to be seen whether there is a time limit or not on the form. One might imagine if so, there are two possible outcomes, Luffy dies from cardiac arrest or his blood pressure returns to normal. This is not something we know yet but it seems Luffy has control over the form as he can shift out of it at will.

So why have I decided to go with Gear 2nd instead of Gear Second or Second Gear or Gear 2 as it is written in the comic? Well, personally I'd love to call it Gear Second but that simply doesn't get across the fantastic bold "2" that Oda blatantly wrote as the chapter title where we first saw it in use. The romanized Japanese reads as 'gia 2' where the 2 is spelled in yomigana as 'sekando'. So the fact that he intended the 2 to be read as 'second' is without question. As far as leaving in the 2 in my translation, it just seems to express the Japanese name of the attack which Oda wrote for a purpose whereas the 'nd' clearly indicates the proper reading in English. And why not reverse/correct it to "Second Gear"? Because Oda's Japanese, not stupid. If he wanted to write Second Gear, he probably would have. It's not a simple spelling error, it's an entirely different syntax so I'm not going to mess with it.

Regarding the organization of the attacks listed here, since literally all of Luffy's attacks are leveled up but don't necessarily all have different names(such as Gomu Gomu Whip, Stamp etc) just for the sake of keeping this as accurate as possible for reference purposes, all attacks performed while in Gear 2nd despite their names will be listed here.

Name of Attack	Translation	Used Against	Location in Manga	Special Notes
Gomu Gomu no JET Pisutoru	Gomu Gomu JET Pistol	Blueno	Vol.40 pg206-207. Vol.43 pg181. Vol.44 pg19*, 116.	Holding out his left palm Luffy uses his fingers as a target to aim at his opponent. When his target is acquired he fires off his right arm similar to his normal Gomu Gomu Pistol attack only at a tremendous speed.
Sutanpu	Stamp	Blueno	Vol.40 pg208.	Luffy sends the sole of his left foot into the face of his opponent before they know what has hit them.
Gomu Gomu no JET Bazu-ka	Gomu Gomu JET Bazooka	Blueno, Lucci	Vol.40 pg212-213. Vol.43 pg186	Rushing his opponent Luffy prepares as he would for the normal Gomu Gomu Bazooka but stops short in front of his opponent and unleashes his double-handed attack in a furious near-invisible blast at point-blank range.
JET Uippu	JET Whip	Lucci	Vol.43 pg184.	A blinding long-range sweeping whip-like kick that has a larger impact zone than a direct kick.
JET Buretto	JET Bullet	Lucci	Vol.44 pg119.	Luffy puts all of his strength into a solid and fast punch. Different from the standard Gomu Gomu Bullet, Luffy seems to throw back his left hand before driving it home into an opponent's stomach.
Tsuin JET Pisutoru	Twin JET Pistol	Lucci	Vol.44 pg120-121.	Luffy's first original attack in Gear 2nd, Luffy fires off both his fists at his opponent like twin jets breaking the sound barrier. Insane.
Gomu Gomu no JET Gatoringu	Gomu Gomu JET Gatling	Lucci	Vol.44 pg160-161	Unfortunately this attack is somewhat difficult to describe as it moves at such a fantastic speed that it seems Luffy is doing little more than convulsing while the opponent in front of him is ravaged by an awesome maelstrom of blasts appearing on his/her chest. The attack is essentially the same idea as Gomu Gomu Gatling only at Gear 2nd speed meaning we see little more than Luffy's fist disappear and the impact on his target. Since Gatling is already a high speed attack this makes it all the more exciting since as described above the opponent is simply riddled relentlessly with a series of small explosions. It appears that Luffy does not need to aim while performing this attack.

*Not said but unmistakenly performed.

Gear 3rd

Luffy's second 'power up' Geard 3rd, while a completely different concept from Gear 2nd, retains the same idea of expanding Luffy's abilities in an entirely new way essentially upgrading his entire arsenal of attacks. Although first alluded to in Volume 40, it was not certain that this upgrade actually existed until Volume 44. Luffy sticks his right thumb into his mouth and appears to bite down hard on his own digit, right down to the very bone. He then takes a deep breath and plugs his mouth with the same thumb while blowing with all his might. The opening in his thumb forces air into the bone of his thumb and ultimately his skeletal system. His rubber body allows him to manipulate this surge of air which he moves into his trunk. Once there Luffy appears to have an awkward oversized chest resulting from his bones literally stretching and expanding, however, Luffy can now move the air throughout his entire body creating massive appendages at will. So what is the point of all of this? This grants Luffy the ability to pull off his old moves while expanding his appendages to size of a giant. What differentiates this particular attack from something along the lines of Gomu Gomu Balloon is that rather than expanding his lungs which simply stretches his skeletal system, here Luffy is actually expanding his bones, not stretching surrounding tissue which would otherwise result in a fleshy pulp. Now something like Luffy's trademark Gomu Gomu Pistol can be turned into a gigantic flying fist of hardened death. Not wanting to disappoint, Oda showed fans in Gear 3rd's second outing that Luffy can spread the air to multiple appendages at once so, for example, two-fisted Gear 3rd attacks are quite possible.

So what of the inevitable weakness? As of this writing although we've only seen it in practice twice, Gear 3rd is not without its downsides. For one, Luffy's otherwise nimble body becomes much slower as a result of his own increased size not to mention his weight shifting dramatically as he conducts the air throughout his body from attack to attack. Luffy does reduce some of the physical strain by expanding attacking appendages only just before attacking with them. This saves him the stress of moving around a gigantic arm or leg and instead uses the weight to his advantage. Again, pretty smart move for an otherwise dim guy. The biggest drawback to Gear 3rd is the 'recoil' so to speak. At this point it does not seem that Gear 3rd is limited by time, however, when Luffy exits Gear 3rd by means of a tremendous exhale, the amount of air leaving his bones seems to be greater than that which he put in, effectively shrinking him into some kind of super-deformed Mini Luffy. I could attempt to cook up a scientific explanation for the following but let's just say it's comic book biology. Luffy cannot do much more than struggle or run while in this shrunken form. The amount of time he spends shrunken is roughly equivalent to the time he spent in Gear 3rd so technically while it isn't a time-limited power up, the longer he uses it the more dangerous it becomes if he doesn't take his opponent down. When the determined time passes, Luffy pops back into his normal self ready for action.

A few fun facts about Gear 3rd, normally Luffy is immune to bullets but they still enter his body and stretch him out before being launched involuntarily back out. However, the part of his body with the inflated bones are actually impervious to bullets as they simply stop dead upon impact.

An interesting choice by Oda is how he chose to describe the 'air' Luffy injects himself with. When first explaining the power up, Luffy says that he fills himself with 'air' written in kanji. However, the yomigana for 'air' reads as 'pawa-' or 'power'. One might read this as him saying 'air power' or that Luffy considers the air used in this way to be raw power. Either way nifty stuff.

Again, as with Gear 2nd, if any attacks pop up without name changes I will list them here regardless so long as they are performed while he is in Gear 3rd. One more little observation, Luffy seemed to switch many of his attack names that were previously in Japanese to English. I will make note of this where present. Oh, and as for the 'gigant' part of the attacks, the Japanese kanji present is read as 'kyojin' literally giant. However, his choice of 'gigant' for the furigana pronounciation, while understood in English as meaning giant, is actually of European origin (Norwegian, Danish & Romanian) but commonly used in Japanese hero or tokusatsu programs not to mention video games. Furthermore the possessive article 'no' is present in the traditional Japanese naming of the attacks which makes all them "Giant's _______ ".

Name of Attack	Translation	Used Against	Location in Manga	Special Notes
Hone Fuusen	Bone Balloon	Self	Vol.44 pg42	After biting into his thumb, Luffy inflates his bones by forcing air into them. This technique initiates Gear 3rd and by bringing it to different parts of his body, in addition to increasing his appendages in size, he can even deflect attacks.
Gomu Gomu no Giganto Pisutoru	Gomu Gomu Gigant Pistol	Lucci	Vol.44 pg44 & 45	Luffy shoots his left hand behind him and then pulls it forward simultaneously enlarging it to the size of a giant's fist which he sends flying into his opponent.
Gomu Gomu no Roketto	Gomu Gomu Rocket		Vol.44 pg56	Identical to his normal Gomu Gomu Rocket except for the bony mass in his trunk. We have yet to see him use this offensively.
Gomu Gomu no Giganto Akkusu	Gomu Gomu Gigant Axe	Marines, Lucci	Vol.44 pg58 & 59	Luffy extends his left foot straight into the sky and when it reaches the desired height, Luffy fills his foot with the Bone Balloon and then brings his giant foot crashing down on his opponent(s).

Yet to be Listed Conflicts

The last published One Piece data book, One Piece Yellow, covered events through Volume 45 but did not include a detailed battle list such as the one found in One Piece Blue which listed major battles through Volume 24. As such I've taken it upon myself to create a rather complex (some might say needlessly so) rubric for determining what constitutes a 'conflict'. If you read this list or the list for any crew member and think to yourself, "Hey, why didn't he include the part where ____", chances are the answer to your question is somewhere in there. My goal was not to create a list of every time two characters bumped into each other, but rather where there existed a serious conflict of sorts. So here is my rationale for what constitutes a conflict and the time-frame in which it took place.

Unlisted Conflicts

The requisites for some battles are questionable. It appears that if only one punch (or kick or whatever) is thrown, then it does not count as a battle (except in the very first bout listed). There are also different types of conflicts, (meaning other than throwing punches or kicks), which are not listed. These are my opinion and were not officially listed.
