Law's abilities (chapter 9)

I did not personally type any of the techniques below, it's simply more convenient for readers as some type of reference tool.

Techniques:

[ROOM]

ROOM (ROOM Rūmu?): The precursor to all of Law's techniques, Law creates a spherical space around his targets, in which he can manipulate anything he wants in a variety of ways; he cannot perform any of his other techniques outside of this spherical area. This was first seen used against a Marine soldier during the escape from the Human Auctioning House. He can hold off on the activation of his ROOM by creating a small circle around his hand,[2] which later will expand to form the ROOM itself.[31] The size of the ROOM can vary from a few meters wide to surrounding entire buildings and mountains, although larger ROOMs require more effort to maintain. The color of the ROOM is transparent, with only the boundaries visible in a light blue aura, so Law can keep his ROOM unnoticed by enemies if he expands it to a size beyond their line of sight.[19] Despite the ROOM being stationary, in both One Piece: Gigant Battle 2 and One Piece: Super Grand Battle X, it can be "carried around" as Law can create a ROOM around himself but cannot place it anywhere else if so; though there are also times where for his subsequent techniques, Law himself does not need to be within a ROOM for them to take effect. Depending on the source of media, ROOM is either written in all capitals in English text (ROOM), or in katakana.

[Amputate]

Amputate (Anpyutēto?, literally meaning "Severance"): Law's basic offensive technique. Law cleanly cuts his target without actually harming them. Law's sword doesn't actually have to make contact with the enemy to cut the target apart. The separated body parts seem to maintain a connection similar to Buggy when using his Bara Bara no Mi powers. While Law has never called this technique before using it, he named it while explaining Radio Knife.[32] Amputate also seems to be necessary when performing operations, in order to extract narcotics from patients, as he did so on the drug addicted children on Punk Hazard.[33] Law first demonstrated this move against a Marine soldier outside the Human Auctioning House in the Sabaody Archipelago, using it in combination with "Shambles". The literal reading of the kanji is setsudan (with amputate being one of its meanings), while an amputation is the removal of a body extremity by trauma, prolonged constriction, or surgery.

[Radio Knife]

Radio Knife (Rajio Naifu?): An advanced version of Amputate. Law charges his sword with electricity in a similar manner to his Counter Shock move and then quickly slashes his enemy, which results in the target being separated into several segments while also suffering an electric shock. It was used for the first time against Trebol inside his ROOM after using Shambles to swap his position with Doflamingo.[34] The cutting itself, like Law's regular slash attacks, is not harmful; however, it differs from them as it prevents the target from briefly being able to reattach their own body, and is meant to be a counter to any abilities where one can re-assemble themselves from Law's original amputation abilities.[35] A radio knife is a surgical instrument that uses a high-frequency electric arc to cut away or through tissue. In Pirate Warriors 3, Law performs it the same way during the attack's debut; through a sideways somersault/side flip to his right while re-sheathing his nodachi. However, in One Piece: Burning Blood and Jump Force, Law instead slashes his target multiple times instead of slashing once with a different type of acrobatic flip, and the damage visibly occurs as soon as Law re-sheaths his blade upon successfully connecting; also in the former game it can be used by Law only in his Duel DLC form.

[Shambles]

Shambles (Shanburuzu?): Within the space created with ROOM, Law can switch the places of any object inside the space. An example is when he switched a decapitated Marine's head for a cannonball coming towards him, attaching the ball of iron back to where the Marine's head used to be. This was first seen being used against a Marine soldier during the escape from the Human Auctioning House.[36] Interestingly, it is shown that he can bring objects to himself without the need for switching with another object. He can also use this move to switch himself with other objects in order to dodge attacks or for transportation purposes. In the VIZ manga, it is called Chambres, which is French for "rooms," while in the FUNimation dub, it retains its original name.

[Jinkaku Ishoku Shujutsu]

Jinkaku Ishoku Shujutsu (Jinkaku Ishoku Shujutsu?, literally meaning Personality Transplant Surgery): During his confrontation against the Straw Hat Pirates, Law showed that he can use Shambles to swap non-physical items such as souls, effectively putting one person in another one's body, though before he can do this he needs to do a thrusting motion at each person, to bring their "heart" out,[4] although if the 'hearts' are already not in the original body he simply needs to make a gesture without the thrusting motion. In the case of Tashigi, switching hearts made her lose consciousness. He later used this attack to bring Franky and Tony Tony Chopper back to their original bodies. This technique was named by Doflamingo.[37] In the Viz manga, this is called the Personality-Switching Surgery.

[Takt]

Takt (Takuto?): Law uses his ability to levitate an object within his ROOM in a telekinetic manner. To use this technique, Law performs a lifting motion with his index finger (by pointing upwards). This technique is first seen being used against the G-5 Marines, and is powerful enough to lift a battleship and some of the surrounding water into the air.[25] He can also use Takt to raise stone thorns from the ground to impale his enemies. Takt is German for "cadence" or "tact", in some forms of One Piece media (such as the Pirate Warriors series), it is even written with a c.

[Scan]

Scan (Sukyan?): Law scans people inside his ROOM by imbuing his sword with the fruit's energy and beaming it through the crowd, using it much like an x-ray machine. This allows him to see the location of any items on the scanned people, selectively swapping away any items they may have on their person. It was first used to steal all the Den Den Mushis from a group of G-5 Marines.[4] In the Pirate Warriors series, it functions similar to the "Scope" ability used by Chopper, implying that Law can use this ability to also find weakpoints on one's person as well.

[Mes]

Mes (Mesu?): Law strikes his opponent in the chest with his bare hand, causing their heart to expel out of their body, encased in a glass-like cube. This attack leaves a cube-shaped hole on the opponent's body where the heart was. It presumably tires the victim in some way, since Smoker panted heavily after Law succeeded at depriving him of his heart, although it does not kill the victim. It was first seen being used on Smoker.[13] Since all body parts severed with Law's abilities still act as if they were still intact, squeezing or beating the heart-cube inflicts great pain and internal damage to the victim, making this technique suitable for subduing and controlling people.[38] Puncturing the heart will cause instant death.[39] Mes means "Scalpel" or "Knife" in Dutch, which is what the Japanese term for scalpel, Mesu, is derived from. In the Viz manga and FUNimation subs, it is called Scalpel.

[Counter Shock]

Counter Shock (Kauntā Shokku?): Law places both of his thumbs onto his opponent's chest and releases a strong electrical surge like a defibrillator. This technique was strong enough to defeat Scotch.[26] He can also use just his thumbs for this technique as shown in his battle with Vergo.[31] Later, it was shown that he can use it with just one hand while the other was cut off.[19] Later on, Law was able to hurt Big Mom with this attack. A countershock is an electric shock that is applied to the chest to restore the normal rhythm of the heart. In the Pirate Warriors games, Law is able to send a whole electrical current through an entire ROOM as well, in order to strike multiple targets; in Pirate Warriors 3, Law can also perform it through firing an electrical forward torrent if used during a Kizuna Rush Special Attack. Law is also able to send a shock through another surface as well, such as through the ground while inside a ROOM in One Piece: Great Pirate Colosseum. In most of these cases, Law himself does not need to properly contact a target in order to unleash the surge. Oddly enough in Super Grand Battle! X, as Law's side strong attack, he is able to use it without an active ROOM.

[Injection Shot]

Injection Shot (Injekushon Shotto?): While aiming at his target, Law rushes towards them with his sword stretched out in order to stab them. Once the sword connects, Law makes it "fire" like a gun, making the target bleed in the aimed spot while pushing them back a fair distance.[40] Law's signature ability of being able to cut objects from afar can still be used while performing this move, as seen when he cut through Trebol's Hanamizu Shinken Shirahadori without having to touch it with his sword, but the move can still be blocked by hitting the blade from the side. It was first used against Trebol, but was interrupted by Doflamingo before it made contact.[35] Its first successful use was against Doflamingo himself.[40] A targeting reticule similar to his Scan also appears on Law's hands or on the blade itself while he is preparing the attack. Only the "injection" part of the attack's name is rendered in kanji, via its literal reading being "chuusha". Via its debut appearance outside of the manga in One Piece: Pirate Warriors 3, the gun-shot sound is not applied; while in Burning Blood, the force of the attack is enough to fire a blast of energy forward from a distance upon stabbing. In the former case however, the ROOM created beforehand from Law's prior attack strings leading up to the C4~2 (Square x3, Triangle x2) input or his R1 ability will oddly enough, disappear when Law prepares and unleashes the attack despite Injection Shot being a ROOM-based technique.

[Gamma Knife]

Gamma Knife (Ganma Naifu?): This is Law's strongest technique. Law creates a short blade of energy before stabbing his opponent with it. This technique destroys his victim's internal organs without leaving any external wounds. According to Law, not even someone of Doflamingo's caliber can survive this. This was first used to fatally wound Doflamingo, though he managed to mitigate the worst of the effects by stitching his damaged organs back together with his string ability.[19] Later on, Law was able to injure Kaido with this technique.[41] A gamma knife is a method of radiosurgery which is used to treat brain tumors. In One Piece Bounty Rush, Law teleports a certain distance and then uses gamma knife which deals a lot of damage and leaves the enemy stunned. In the anime and other recent media, the color of the energy is shown as pale-green.

[Sterben]

Sterben (Suteruben?, literally meaning "Blade of Death"): A technique used when Law had his right arm severed by Doflamingo. After using Takt on his severed arm, Law makes it spin. Because the arm is still holding Law's sword, it effectively ends up acting like a buzzsaw that cuts the opponent in a vertical motion. It was first used to defeat Trebol.[42] However, via one of Law's DLC forms in One Piece: Burning Blood, the attack is instead used by levitating and buzzsaw-twirling the blade in front without Law's arm being detached and gripping it, along with purple energy that trails his sword emitted by his Radio Knife. It is also used the same way in Great Pirate Colosseum and in Pirate Warriors 4, only without the said energy in the former game. Sterben means "to die" or "dying" in German, often used as a term for hospital deaths. The kanji's literal reading is Shi no Tō.
