Rokushiki

Rokushiki (六式) are special, superhuman skills that are the base of an advanced hand-to-hand combat technique.

They first appeared in Chapter 342 and Episode 242. It was first introduced being used by the CP9 agents. Later, some other marines demonstrated this technique. Coby and Helmeppo used their (recently learned) ability against Luffy and Zoro. Vice-admiral Momonga along with other officer used it to confront Luffy at Marineford.

It is exactly unknown how much the Rokushiki technique is spread around the Marines. Vice Admirals are shown using some Rokushiki techniques. Outside weapons and Devil Fruits, the series is very obscure about which technique overall Marine combatants use.

Kami-e
... But there's no art to being hit... The Kami-e (紙絵) makes the users' body go limp in order to avoid any attacks, and float like a piece of paper. In the Viz Manga, this is called Paper Art.

Variations of Kami-e

 * Seimei Kikan: Kami-e Bushin (生命帰還　紙絵武身): Used by Lucci. Using Seimei Kikan (Life Return, the same Sennin technique as Kumadori), he makes his half-leopard form smaller and lighter, and possibly increasing his speed. At any rate, he is much more agile in this form, and harder to hit - as opposed to his hulking normal half-leopard form. In One Piece: Unlimited Adventure (the FUNimation dub) this was called Rebirth: Sketch Form.
 * Seimei Kikan: Kaijo (生命帰還　解除): Used by Rob Lucci while in his smaller half-leopard form. It cancels his Seimei Kikan: Kamie-e Bunshin, and returns to his larger, stronger half-leopard form.


 * Kami-e "Slime" (紙絵　『軟泥」): Used by Fukurou. Instead of the body becoming limp like paper, it stretches and moves in ways slime or sludge would move in order to avoid attacks. In the Viz manga, this is called Paper Slime.

Geppou
... one can also kick the air to float... The Geppou (月歩) allows the users to actually jump off the air itself, allowing them to stay in the air for much longer than usual. CP9 members can use this technique to cross great distances without ever touching the ground, or set themselves up for swift, aerial attacks. No CP9 member has yet shown any variations of the technique, with the exception of Lucci's Kamisori and Fukurou's one legged Geppou (which in theory, other Geppou users may have the capability to do). It has once been used aggressively by Lucci, performing a suplex-styled move while Luffy clung onto his back. The impact left a rather large crater in the floor. While the technique itself affords several advantages in both in and out of battle for the user, it has but one major weakness: since its usage depends heavily on the user's legs, restraining or pinning down any major parts of their lower body can significantly disrupt Geppou. This was seen during Fukurou's fight with Franky, where the latter managed to grab on to one of the CP9's legs, noticeably affecting the technique. However, it should noted Lucci has been seen kicking off the air with one leg at a time rather like hopping and keeping himself afloat. In the Viz Manga, this is called Moonwalk.

Rankyaku
It is possible to be fast enough to cause slicing winds... The Rankyaku (嵐脚) is a powerful projectile technique, in which the users starts by kicking at very high speeds and strength, sending out a sharp "air blade" that can slice objects and greatly damage a human body. In the Viz Manga, this is called Tempest Kick.

Variations of Rankyaku

 * Rankyaku "Hyoubi" (嵐脚　『豹尾」): Used by Lucci in his half-leopard form. Lucci creates a large, powerful Rankyaku in the shape of a swirl, which is launched at the enemy like a razor blade. When it hits the opponent, he/she takes damage and is stunned.


 * Rankyaku "Gaichou" (嵐脚　『凱鳥」): Used by Lucci. Lucci creates a large Rankyaku in the shape of a bird, but instead of using his legs, he uses his claws in his half-leopard form. This Rankyaku has a much wider range, greater attack power, and is capable of cleaving steel - something not witnessed from other variations. The cut also seems more focused, instead of flickering and jagged like a normal Rankyaku. The "Gaichou" can also mean "Injurious Bird".


 * Rankyaku "Sen" (嵐脚　『線」): Used by Kaku and Nero in a stomping action. The air is blasted straight ahead in a line towards the opponent like a bullet, instead of in a curve as witnessed in the normal version.


 * Rankyaku "Hakurai" (嵐脚　『白雷」): Used by Kaku. A much more powerful form of Rankyaku that is used by using both legs, it appears to cut the air in a larger area.


 * Rankyaku "Ran" (嵐脚　『乱」): Used by Kaku. After using Geppou to launch himself into the air, Kaku stabs his swords into the ceiling to stay in the air, then launches multiple Rankyakus with both legs. Each cut is smaller than a normal Rankyaku. Lucci also used a version of this attack (without the swords) during his fight with Luffy, but he did not name it. The "Ran" can also mean "War".


 * Rankyaku "Amane Dachi" (嵐脚　『周断」): Used by Kaku in his half-giraffe form. In this attack, he spins around quickly in a circle on one hand while performing Rankyaku to create a circle shaped Rankyaku which radiates outward. The attack was powerful enough to cut through the outer walls of the Tower of Justice in all directions. It can also be used to send an enormous mass of Rankyaku at the user's opponent. Kaku says that this is his most powerful Rankyaku.


 * Rankyaku "Kiri Shigure" (嵐脚　『麒麟時雨」): Used by Kaku in his half-giraffe form. After turning himself into a cube with Tekkai "Mushikaku", Kaku uses Rankyaku towards the ceiling with all four of his limbs. There, the mass of small Rankyaku cuts bounce back, falling like rain on the enemy. The "Kiri" part of the name can also mean "mist".


 * Rankyaku "Neji Hakujin" (嵐脚　『ネジ白刃」): Used by Kaku in his half-giraffe form. He does a normal Rankyaku after using his Kyoku Bigan Kirimanjaro, then twists his neck into a screw so the Rankyaku spins in a drill motion.


 * Rankyaku "Roudan" (嵐脚　『龍断」): Used by Kaku in his half-giraffe form. Kaku uses an upward Rankyaku with both of his back legs, creating a large cut similar in appearance to a dragon's fang.


 * Rankyaku "Shuriken" (嵐脚　『手裏剣」): Used by Kaku. Kaku fires multiple Rankyaku blades in the shape of shuriken.


 * Rankyaku "Korou" (嵐脚　『孤狼」): Used by Jyabura in his half-wolf form. In this attack, the Rankyaku-cut skips across the ground, bouncing in curves towards the opponent.


 * Rankyaku "Lupus Four" (嵐脚　『群狼連星」): Used by Jyabura in his half-wolf form. In this attack, Jyabura shoots four Rankyaku cuts, each in the shape of a wolf, straight at the opponent. Because of their unusual shapes, these Rankyaku seem to explode upon contact rather than cutting, much like compressed air bullets rather than blades. Jyabura has honed this technique so he is able to initiate it correspondingly with Geppou. The kanji of "Lupus Four" is read as "Wolf Pack Synergy/Cooperation".


 * Rankyaku "Renge" (嵐脚 『蓮華」): Used by Kumadori. In this attack, Rankyaku is performed with both legs instead of one, causing multiple cuts on either side of the opponent. The cuts at first appear small and then "blossom" into larger ones, perhaps explaining the name.

Shigan
A bullet isn't needed to pierce the human body. The Shigan (指銃) is a close-quarter combat technique, in which the user pushes their finger into a certain target at a very high speed, leaving a wound similar to a bullet wound, making guns unnecessary. A sharper point is added to this technique when Lucci and Jyabura morph into their half-beast forms, enabling the use of their claws to fire the Shigan like an actual modern bullet. So far, it seems each CP9 member has their own version of Shigan, aside from Blueno, Nero, and Spandam, the latter two not even knowing how to use the technique. The Shigan's shape is derived from the shape of the finger, hence the hit of Shigan will have more of an impact on Luffy's rubber body (which normally reflects bullets) as it is sharper than the round bullet and resembles more modern bullets.

In the Viz Manga, this is called Finger Pistol.

In a fan question on SBS, Oda said that if you got poked in the butt with a Shigan, you'd die. In another SBS, Oda also claimed that the CP9 agents would sprain their fingers when they failed in the technique during training.

Variations of Shigan

 * Shigan "Ouren" (指銃　『黄蓮」): Used by Lucci. This attack is simply a rapid-fire version of the normal Shigan technique that hits the enemy multiple times. In the anime, he is also seen using this technique to kill the captain of a crew who raided the kingdom 15 years ago, but did not name it as "Ouren".
 * Tobu Shigan "Bachi" (飛ぶ指銃　『撥」): Used by Lucci. A projectile version of Shigan that fires sharp air bullets from the fingers, similar to "Rankyaku", and are therefore able to pierce Luffy's rubber body. Unlike other versions, this type of Shigan is launched by flicking instead of jabbing.
 * Tobu Shigan "Mitsubachi" (飛ぶ指銃　『三撥」): Used by Lucci. Same as above, except Lucci launches it three times in three rows. This is an anime only technique.
 * Tobu Shigan "Hibachi" (飛ぶ指銃　『火撥」): Used by Lucci. Same as Tobu Shigan: Bachi, except that it ignites the victim upon impact. This is an anime only technique. "Hibachi" is a type of Japanese grill.


 * Shigan "Madara" (指銃 『斑」): Used by Lucci. Appears as Ouren, but is performed with both hands instead of one and in half-leopard form (meaning that his fingers are clawed), this makes for the ultimate Shigan barrage.


 * Bigan (鼻銃): Used by Kaku, in his half-giraffe form. In this attack, Kaku uses his nose instead of his finger to perform the attack. As his nose is much larger in diameter than a finger, the hole it creates is also much larger than that of a normal Shigan, as well as being completely square.
 * Kyoku Bigan "Kirimanjaro" (極・鼻銃　『麒麟マン射櫓」): Used by Kaku in half-giraffe form. After using Kirin Hodai, he can fire his neck out like a cannon, making his Bigan stronger. The name Kirimanjaro is a reference to "Kilimanjaro", the mountain that shares the same name.


 * Juushigan (十指銃): Used by Jyabura in his half-wolf form. In this attack, Jyabura puts both of his hands together and performs Shigan with all ten of his clawed fingers at once, greatly damaging the opponent.
 * Gekkou Juushigan (月光十指銃): A combination of Juushigan and Geppou. After using Geppou to get himself into the air and subsequently avoid his foe's attack, Jyabura finally uses it to launch himself towards his airborne target in a vertical drop. The added momentum and the vulnerable target makes the following Juushigan more effective, and harder to avoid.


 * Shigan Cue (指銃 Q): Used by Kumadori. In this attack, Kumadori uses his blunt staff in the same way a finger is normally used in Shigan. The Q in the name is a reference to a pool cue, which is held in the same manner that Kumadori wields his staff.


 * Shishi Shigan (獅子指銃): Used by Kumadori. Rather than using his own fingers, Kumadori shapes his hair into the form of hands and repeatedly uses the fingers of said hands to rapidly jab the opponent, similar to Lucci's Shigan "Madara", but less powerful.


 * Jugon (獣厳): Used by Fukurou, this is a very strong punch which is done at the same speed as Shigan, making it even more powerful.
 * Jugon Ougi: "Fukuro Dataki" (獣厳奥義　『梟叩き」): A rapid-fire version of Jugon, in which Fukurou unleashes a flurry of punches at the enemy while using Soru to move around him, in order to strike from all directions.


 * Shinaru Shigan "Whip" (しなる指銃　『鞭」): Used by Kalifa. In this attack, Kalifa pulls back her arm as if to use a normal Shigan attack, then whips her arm out at the opponent at high speed, causing her arm to appear as if it is bending like a whip would, and hits the enemy with her finger. The whip aspect of this variation results in the added effect of the target being thrown forcibly backwards.

Soru
With leg strength explosive enough to seemingly cause one's body to "disappear"... The Soru (剃) allows the users to moves at extremely high speeds in order to avoid attacks, as well as to attack at higher speeds. It was revealed that the principle of this move was to kick off the ground at least ten (10) times in a blink of an eye. Luffy has also learned from this move and was able to use it in his fights against Blueno, Lucci, and Mihawk, though Luffy's own version (via Gear Second) is more powerful and swifter. Coby was seen being able to use this move during his friendly fight with Luffy after the Enies Lobby arc. As Nero lacked the complete training, his Soru is actually more of a swift run instead of disappearing speed seen from other Soru users.

In the Viz Manga, this is called Shave.

Another thing that should be noted of this particular skill is that Kuro's "Shakushi" travels at roughly the same speed as CP9's Soru ability. The difference is that when Kuro uses that technique, he cannot see what he is attacking, or how far he is going, whereas CP9 have mastered this ability and therefore can. The fact that other people, outside of CP9 membership has exhibited being able to imitate the skill (either by copying the move directly or developed their own version of it) suggests that Soru might be the most fundamental of Rokushiki.

Variations of Soru

 * Kamisori (剃刀): Used by Lucci. A combination of Geppou and Soru, where Lucci uses Soru in a zigzag motion in midair, allowing extremely fast movement in 3 dimensions.


 * Soru "Tekkai Dama" (剃　『鉄塊玉」): Used by Fukurou. In this attack, Fukurou spins his body at great speeds towards his opponent using Soru, then uses Tekkai to harden his spherical body.
 * Chou Sokuten Tekkai Dama (超側転　鉄塊玉): A variation on the above technique used by Fukurou wherein he combines his usual Tekkai Dama movements with Geppou to use it in midair.

Tekkai
We've trained our bodies such that we can turn them into "Iron Carapaces" if we so choose... The Tekkai (鉄塊) hardens the users' muscles to the level of iron, in order to nullify damage taken from attacks. However, it can be broken by strong enough forces such as Luffy's various Gears, Roronoa Zoro's Shishi Sonson and Sanji's Diable Jambe. When Tekkai is active, the user is unable to move, with the exception of Jyabura's Tekkai Kenpou. The strength of Tekkai can vary for users with different physical conditions, as a person with a higher level of muscular strength would be able to take stronger forces with his use of Tekkai. Furthermore, despite the increased physical density that one gains when activating this move, one should remember that the user's body is still flesh and blood. Thus, its resistance to other than solid attacks remain pretty much the same, making the user as vulnerable as ever to certain attacks. An example was during Sanji's fight with Jyabura where he used the burning force of friction to incinerate through the latter's Tekkai or when Franky used his actual iron fist to break Fukurou's Tekkai. As such, even masters of Tekkai are far from indestructible. However, for Rob Lucci, he seemed to be able to resist even cannonball flames at 13 years old.

In the Viz Manga, this is called Iron Body.

Variations of Tekkai

 * Tekkai "Utsugi" (鉄塊　『空木」): Used by Lucci. This form of Tekkai is used entirely as a counter, where the purpose isn't to absorb damage from the attack, but to transfer the shock of the attack back to the attacker, which can lead to broken bones in a normal human body.


 * Tekkai "Mushikaku" (鉄塊　『無死角」): Used by Kaku in his half-giraffe form. Kaku bends his neck and legs to shift himself into a cube. When Tekkai is used in this form, he eliminates the weak points of his body, particularly his neck, and ensures that not a single spot is vulnerable to his following Kiri Shigure, though he looks ridiculous. Pun with "mashikaku", means "perfect square".


 * Tekkai Kenpou (鉄塊拳法): Used by Jyabura. Using Tekkai Kenpou, Jyabura is able to move while using Tekkai. Tekkai Kenpou is also an entire fighting style, with various techniques of its own.
 * Tekkai Kenpou "Ookami Hajiki" (鉄塊拳法　『狼弾」): After hardening his hands with Tekkai, Jyabura punches his opponent.
 * Tekkai Kenpou "Rouga no Kamae" (鉄塊拳法　『狼牙の構え」): Simply called Rouga for short. Rouga is one of Jyabura's forms of Tekkai Kenpou. The way that Rouga is called is a pun in Japanese; oftentimes sentences end with darou, approximately meaning "probably". Sometimes, however, the particle ga would be added onto the end of a sentence to make it seem more direct. This is the way Jyabura normally speaks, so he simply replaces where he would normally say darou ga (だろうが) with da rouga (だ狼牙).
 * Tekkai Kenpou "Rouba no Kamae" (鉄塊拳法　『狼芭の構え」): A form of Tekkai Kenpou, in which Jyabura seems to combine Tekkai with Soru in order to move at extreme speeds.
 * Roukaru Area Network (狼狩エリア・ネットワーク): While moving at high speed, Jyabura slashes at his opponent with both hands. Because of his high speed, it appears as if he was attacking with multiple hands. "Roukaru" is the Japanese way of pronouncing the word "local", making this attack a pun on "local area network".
 * Tekkai Kenpou "Don Pou Rou" (鉄塊拳法　『重歩狼」): A punch to the opponent's stomach with Tekkai in use. "Dongpo Rou" can also mean simmered square pork meat in Chinese.
 * Tekkai Kenpou "Maten Rou" (鉄塊拳法　『魔天狼」): Jyabura flips onto his hands, then kicks his opponent up into the air. In the anime, this attack was instead portrayed as a jumping kick. "Matenrou" is also Japanese for "skyscraper".


 * Tekkai "Rin" (鉄塊　『輪」): Used by Blueno. Blueno uses Tekkai and kicks one leg into the ground and starts rotating his legs at a fast speed, causing his legs to simultaneously slam into the ground on a set path toward his opponent. It also seems to incorporate Rankyaku, as the legs leave blue traces in the air like a normal Rankyaku shockwave and a glancing attack cut a small amount of Luffy's hair.


 * Tekkai "Sai" (鉄塊　『砕」): Used by Blueno. After using Tekkai to harden his body, Blueno then uses Geppou to project himself towards his opponent, smashing them.


 * Tekkai "Gou" (鉄塊　『剛」): Used by Blueno and Kumadori. Visually, the move differs from the ordinary Tekkai in that the user visually tenses his body even further while standing still; the ordinary Tekkai could be activated seamlessly. According to Blueno, it is his strongest form of Tekkai.

Rokuougan
Let me show you... the most powerful attack available to those with full mastery of Rokushiki. The Rokuougan (六王銃) is the secret and ultimate attack of the Rokushiki style. Rob Lucci states that only those who have absolute mastery of the other six skills can have access to this seventh skill. The user places both his/her fists right in front of the target and launches a devastating shock wave, which seems to have the same power to an Impact Dial or even a Reject Dial (depending on the amount of energy absorbed by the dial), and causing massive internal injuries. This is only used during desperate situations as Lucci is always shown panting after using it.
 * Rokushiki Ougi: Rokuougan (六式奥義　六王銃): Used by Lucci. This is the ultimate Rokushiki technique that can damage an opponent internally, similar to the Impact Dial, or of equal or more strength to the Reject Dial, but the technique is considered much more powerful, and can be performed without the side effect of great pain to the user. It appears to be two fists held at close range that can damage the opponent with a blast powerful enough to cause even Luffy to cough up blood and come close to death.
 * Sai Dai Rin: Rokuougan (最大輪　六王銃): Used by Lucci in his half-human half-leopard form which gives him the advantage of having a tail which is used to immobilize an opponent if they attempt to escape it, this technique is used in the same way as Rokuougan, except now with a larger attack radius and greater attack power. The move is so powerful that the shock wave it sends out can punch a hole in rock even after going through its intended target, similar to Bartholomew Kuma's Pad Cannon technique.
