User:Thy mighty overlord

In his youth, after Law realized he was dying, he went to Doflamingo to join the future Warlord of the Sea's crew, planning on causing as much devastation as possible to the world before dying. Doflamingo accepted Law, and while part of the Donquixote Pirates, he learnt marksmanship from Gladius, martial arts from Lao G and swordsmanship from Diamante, in Doflamingo's hope that they would find a cure for Law and raise him into being the third Corazon.

Law is shown to have a very strong will as he, along with most of his crew, proved resistant to Rayleigh's burst of Haoshoku Haki that took out almost everyone in the Auction House. This feat caused Rayleigh to comment on him being a fearsome pirate. He was also able to withstand the clash of Haoshoku Haki between Luffy and Doflamingo. Like Jinbe and Eustass Kid, Law is also immune of Big Mom's "Soul Pocus" when showing he has no fears towards the Emperor.

Even Donquixote Doflamingo commented to his subordinates at Punk Hazard about Law's potential while comparing it to Luffy's, which Doflamingo witnessed himself during the war at Marineford two years ago. Doflamingo saw talent in Law and intended to make him into his right-hand man. He reserved the Heart seat for Law, showing that the latter is considered on the same level as the elite officers of the Donquixote Family. Vergo was only able to keep ahead of Law because he had the latter's heart at the time, a situation that immediately reversed after Smoker (reluctantly) helped Law to retrieve the organ.

He is also apparently quite fearless, as he allowed several Marines to get within close-range of him on Sabaody Archipelago, despite being a long-range fighter. During their stay at Sabaody Archipelago, the Kid Pirates and Heart Pirates were caught in a battle with a Pacifista. The end of the battle was unseen, but since they reappear during the Marineford Arc, it can be assumed that they either defeated the Pacifista or managed to elude it. Kizaru mentioned that the Heart Pirates did a good job at running away.

Sometime during the timeskip, Law became so powerful and infamous that even the ruthless G-5 Marines were deeply fearful of him. His bounty soon surpassed Luffy's at the time, and brought a hundred pirates' hearts to the World Government, earning his position in the Seven Warlords of the Sea. Law battled and defeated Smoker, a Vice Admiral and Logia user without getting injured. He later defeated Vergo in one move, whereas in the past, it was impossible to hurt him because of his powerful Busoshoku Haki. In Dressrosa, he was strong enough to face and counter attacks from the Admiral, Fujitora, and fellow Warlord, Doflamingo at the same time; then dealt severe damage to the latter near the end of the arc, but could not defeat him.

In Wano Country, Law was able to injure the Emperors, Kaidou and Big Mom, both being known for their nigh-impenetrable durability throughout their battle, earning recognition from them. During both his and Kid's fight against Big Mom, his awakened powers were able to deal significant damage to the Emperor who soon empowered herself with a year of her lifespan, while wielding her special Homies, Hera, Prometheus, and Napoleon, all of which had become stronger and more in-sync. In the end, due to their joint efforts and nullification of her Devil Fruit powers, he and Kid were able to defeat Big Mom, the fearsome Emperor.

Having defeated the former Emperor, Big Mom, Law gained a bounty of 3,000,000,000, making him one of the most dangerous pirates in the world; with his new bounty matching that of the current Emperor and rival, Monkey D. Luffy.

Physical Abilities
In addition to his Devil Fruit, Law underwent an extremely rigorous combat training regimen under the Donquixote Pirates as a child, attaining incredible superhuman physical prowess. While still a twelve-year-old boy, he was already strong enough to throw Rosinante, a very tall and large man, by grabbing him by the leg.

Additionally, he has the physical power to block Doflamingo's extremely powerful Overheat string which shook the Thousand Sunny with just his sword. He easily wielded Kikoku, a sword as tall as himself with great speed, and is able to slice enemies faster than they can react as well as keep up with Doflamingo.

Law is very skilled at hand-to-hand combat, having been trained in this aspect by Lao G. In the anime, Law was able to hold his own against Luffy, an extremely powerful fighter in a fist fight, when Breed forced Luffy to fight Law through the Peto Peto no Mi. With Busoshoku Haki, Law could block against Doflamingo's Goshikito with his arms crossed in a defensive stance. Even at age 13, Law could defeat both Penguin and Shachi, who were bullying Bepo, a mink who is a natural born fighter, impressing them to the point they swore loyalty to him.

Durability and Endurance
Law has displayed immense levels of physical endurance, as he had his heart directly crushed to the point where he lost consciousness, only to recover shortly afterwards. In addition, he was also capable of enduring a prolonged brutal beating from Vergo which resulted in him becoming severely bloody before defeating him in a single blow once Smoker had retrieved his heart. Even as a child dying from the incurable Amber Lead Syndrome, Law was able to keep up with the very harsh training regimen of the Donquixote Pirates of which even adults could not keep up with. Even when his disease reached a fatal stage, he could survive two ruthless beatings from Vergo.

Even when he was defeated and injured by Donquixote Doflamingo and Admiral Fujitora, as well as pinned to the ground by Issho's Devil Fruit power, Law was able to quickly recover and escape.

During his second confrontation with Doflamingo, Law was able to fight him and, even though he was still wounded from their first encounter as well as having his right arm severed while being brutally assaulted further, he was able to continue fighting and deal Doflamingo a severe wound with his Gamma Knife move. Also, even though Law was incapacitated by Trebol, he was still able to use his Devil Fruit powers to control his severed arm as well as defeat the officer.

During the Raid on Onigashima, Law took multiple hits from the two Emperors, who'd started taking them seriously and from Kaidou in his human-beast form. Once taking Big Mom's Tenman Daijizai Tenjin later taking Kaidou's Raimei Hakke but having enough strength and stamina to continue challenging Big Mom, something that Luffy couldn't previously do.

Law continued taking blows from Big Mom before and after entering her empowered, giant form, but had enough stamina to continue on, while also using his awakened powers, then using his strongest techniques thus far to deal a devastating blow.

Medical Expertise
Since childhood, Law was already well versed in medicine, having attended an academy for medical science, while his father, the best doctor of Flevance, personally taught him the more intricate procedures. Even after he joined the Donquixote Pirates, he still retained a profound understanding of medical science, as he was able to use the Ope Ope no Mi to remove all traces of the Amber Lead inside his dying body. This was noteworthy as he was able to find a cure for the poisoning that was said to be incurable and live past the age he was supposed to die at. His medical aptitude was what led Donquixote Rosinante to conclude that Law was most compatible with the fruit, which prompted him to secure the Ope Ope no Mi for Law after he received information from both his brother and Sengoku of the fruit's present whereabouts at the time.

Law earned the nickname "Surgeon of Death" due to his immense surgical skills in addition to his formidable combat abilities. He was able to simultaneously operate on both Luffy and Jinbe right after both of them barely escaped a murderous Akainu who inflicted brutal life-threatening injuries that left them on the brink of death and was successful in treating them. The mere fact that he was able to stabilize Jinbe's condition strongly hints that Law's medical expertise is not limited to human anatomy alone (though human and fish-men share the same blood, so it is possible that they have similar anatomies). He later volunteers to find a cure for the children's condition at Punk Hazard, showing that he is also very knowledgeable in pharmacology. The fact he was able to apply pharmacology knowledge into his Devil Fruit powers so as to remove most of Caesar's deadly NHC10 drug out of the children's bodies, though not completely, is a noteworthy feat and is something even Chopper was amazed by.

The spatial powers given to him by the Ope Ope no Mi allows Law to perform even the most complicated and difficult surgeries perfectly with great ease, as they allow him to cut a patient's body open and remove organs without damaging any tissues, leaving scars, or causing the patient to bleed a single drop of blood while removing any disease-causing impurities as well as poisonous substances and narcotic drugs from the patient's body. This was demonstrated, off screen, during the conclusion of the Punk Hazard Arc, in which he had treated the children with a series of surgeries that involved cutting the children's bodies apart in a manner that initially made Chopper believe he had killed them.

As a boy, Law was able to remove all the poisonous Amber Lead inside his dying body thus curing himself of the Amber Lead Syndrome while proving his capability to use the Ope Ope no Mi for treating even incurable diseases. Law could also apply his medical knowledge of anatomy into his Devil Fruit powers for combat, such as aiming his Sterben technique directly at Trebol's real body which kept hidden under a large amount of mucus disguised as a large body or precisely removing important and delicate organs of powerful enemies such as the heart which would render them vulnerable to lethal harm such as death, which was proven when Law extracted Monet's heart with his power and gave it to Caesar, who fatally stabbed Monet's heart while bypassing her defensive powers as a Logia user, effectively killing her, Law, as well as Sanji and Capone Bege, was able to keep Caesar who is also a Logia user and a dangerous criminal under complete control due to having taken his heart hostage which was removed in a similar fashion, and the fact he used his anatomical knowledge to invent the Gamma Knife technique on his Devil Fruit which could fatally rupture and destroy the internal organs of even a Warlord of the Sea like Doflamingo further proving the fearsome way Law could actually weaponize his medical knowledge. Likewise, he also managed to pinpoint Kaidou's heart in his Dragon form to cause him significant damage with his Gama Knife.

Tactical Skills
Law is a very crafty and opportunistic leader and also a highly skilled strategist, being the only member of the Worst Generation to voluntarily rest in the Paradise half of the Grand Line for at least two months before entering the treacherous region of the New World, proving great caution and tactical preparedness. He obtained the title of Warlord of the Sea in order to avoid detection of his actions and easily sail through the New World. While in Punk Hazard, Law secretly swapped numerous Seastone chains with ordinary chains as a future precaution that proved to be critical in allowing him to stealthily escape from Caesar's cage that is about to be exposed to the deadly Shinokuni gas.

As Vergo noted, Law concocted a multi-layered plan to cripple Doflamingo's SMILE trade by destroying the SAD production facilities on Punk Hazard as well as abducting Caesar, the only person who knows how to create the unique substances. Through this plan, Law managed to force Doflamingo, an extremely cunning and resourceful pirate in his own right into an utterly disadvantageous choice of quitting the Seven Warlords of the Sea and facing the Admirals or keeping his position and face Kaidou's wrath. He was able to fool Doflamingo into believing he killed him by swapping places with a foot soldier when the latter shot him repeatedly and retaliated when the latter's guard was down. When badly weakened, Law resort to tactically defeat Trebol, tricking the latter into letting his guard down to finish him off with his Sterben technique.

When Kin'emon's original plan had been exposed by Kanjuro, Law was able to instantly formulate a backup plan, taking advantage of Luffy and Kid's headstrong and reckless nature to create an effective diversion while using it as an opportunity to transport the Nine Red Scabbards to Kaidou's residence by sea using the Polar Tang and his Devil Fruit powers.

Devil Fruit

 * Further information: Ope Ope no Mi

Law ate the Ope Ope no Mi, a Paramecia-type Devil Fruit which allows him to create a sphere of light blue aura, inside which he can manipulate the fabric of space. He can manifest this aura sphere over a very wide area; however, he cannot move the sphere once he's conjured it, he would instead have to dismiss the sphere and create a new one in a different location. Furthermore, Law has to concentrate in order to maintain and use his power, and unlike most Devil Fruit powers, Law's powers directly take a toll on his stamina.

Inside the aura sphere, Law can exert complete control over the fabric of space, referred to as the ability to "operate" on anything within the spherical "operating room"; he can move things within the area of the sphere telekinetically and make things, including himself and other people, swap locations via teleportation. However, he cannot move other people with strong Haki very far, as they possess more resistance to Law's power. He can also swap incorporeal things, such as souls, resulting in the victims' swapping bodies. He is also able to cut things from a distance and without actually damaging them, as well as reassemble things into various combinations; he can even attach living body parts to inanimate objects. Living things cut into pieces by this power remain alive and still able to move, even if the head is removed from the body. Law can use his power to generate high voltage energy; he can generate electrical energy to shock his opponents, and he can generate a blade of energy that he can use to damage his enemies' internal organs without leaving an external wound.

This power can also be used for medical purposes; Law can completely remove harmful matter, such as drugs and diseases, from organic tissue. Additionally, he can attach new body parts to a person's body to replace destroyed body parts. He can also use his power to scan anyone within the sphere in a manner similar to an X-Ray machine.

Awakening
Law has achieved Devil Fruit awakening, allowing him to conjure a variety of special room spheres that are applied directly to specific objects instead of a designated area, meaning those rooms move alongside whatever they are currently covering. With K-Room, Law can adhere a miniature room to his weapons, which then gain the ability to extend as far as he desires, harmlessly bypass anything solid and directly operate on the insides of whatever they may phase through. With R-Room, Law is able to create and throw a room on a particular object and dictate a specific effect to take place in it, like erasing any sound made by the object in question. This directly addresses one of the fruit's biggest weaknesses, which is the stationary nature of its regular field of range. By Law's own admission, he has not fully mastered his awakened powers and using them takes a serious toll on his stamina.

Swordsmanship
Law is extremely skilled in wielding his Nodachi Kikoku, a sword about as tall as he is. Even without using his Devil Fruit abilities, Law is capable of fighting even a Vice Admiral such as Smoker, as he is able to clash against his jitte with little effort and even block extremely powerful long-range attacks such as Doflamingo's Overheat. In contrast to the ranged slashes of traditional swordsman, Law's sword slashes don’t travel but simply provide the cutting effect while his spatial manipulation within his ROOM provides the range. Through spatial slicing, he can dismember people without harming them and attach separated parts in any manner he sees fit.

Law's swordsmanship combined with his Devil Fruit powers enable him to mutilate numerous people at once faster than they can react, easily defeating Kin'emon, a master of Kitsunebi-ryu and one of Wano's most powerful samurai in this manner. He easily defeats Tashigi, a highly skilled swordswoman of the Marines, severing her sword in two in one slash, as well as taking down Scotch and his giant knife in one swift move. He also managed to mutilate Trebol, an enormous man and also one of the strongest members of the Donquixote Pirates.

Law's greatest swordsmanship feats shown so far have been defeating Vergo, one of the strongest members of the Donquixote Pirates, where the wake of his slash was capable of cutting apart Caesar's laboratory and the surrounding mountains and cutting a meteor in half.

Law also managed to wrap the rope created by Donquixote Doflamingo's attack around his sword. He was able to use his sword to quickly parry bullet strings shot at him by Doflamingo.

Marksmanship
Law is an apparently skilled marksman, as he was trained by Gladius in wielding firearms while he was younger. He apparently uses this skill with his Injection Shot technique.

Haki

 * Main article: Haki

Law is able to utilize both basic Haki-types. However, he rarely uses either in combat, being more reliant on his Devil Fruit abilities. Pre-timeskip, Law was aware about the nature of Haki, being knowledgeable about Haoshoku Haki, having seen Silvers Rayleigh knock out the hostiles inside the Human Auctioning House, leaving the non-hostile active. After his fight against Kaidou and Big Mom, he learned that intense enough Haki can counteract the effects of Devil Fruits, something he managed after the battle against the effects of Doc Q's Shiku Shiku no Mi.

Busoshoku Haki
Law is an extremely skilled user of Busoshoku Haki. As he could bypass Smoker's smoke body, thus resulting in him being able to take down the Vice Admiral. Law later hardened his arms to block Doflamingo's Goshikito, which is powerful and sharp enough to slice Fujitora's meteorite and also took out a large portion of the palace, without getting injured at all.

Kenbunshoku Haki
Law possesses the ability to use Kenbunshoku Haki. During the Raid on Onigashima, Law demonstrated great skill in this type of Haki as he was able to sense that Luffy was defeated by Kaidou, and was also able to sense Luffy's Devil Fruit Awakening.

Weapons

 * Further information: Kikoku

Kikoku is a large version of the typical Japanese sword type known as a nodachi. It has an oblong-shaped handguard coated with short white fur, sheathed in a black scabbard decorated by white crosses from the opening to the bottom, and with a small piece of red rope tied near its opening. Law appears to be quite skilled with it, being able to slice up targets from a distance (although this effect is attributed to his Devil Fruit power). Due to its size, Law usually carries this sword over his shoulder (in contrast to the other sword-wielding characters in the series, who either carry theirs on their hips or over their backs); yet in other times, he delegates one of his crewmates (namely Bepo) to carry this sword for him. Law was able to deflect Doflamingo's strings with his sword, which is noteworthy, as Doflamingo managed to effortlessly cut everything else so far.
