Trafalgar D. Water Law

He's an insane man who sent the hearts of 100 pirates to HQ in order to become a Shichibukai!! He's a creep!!

Trafalagar Law is a character in One Piece and a infamous pirate rookie in the Eleven Supernovas.

He is a friendly rival towards Luffy but only hostile towards Eustass Kid.

Personality
Law is an extremely laid-back character, who is nearly always seen calmly smiling. The only times he is shown not smiling was when he is incredibly shocked, explaining something to other people, frowning in deep thought, or deeply embarrassed such as when Chopper was tied on his head due to him being unable to walk. After the time-skip he's not smiling as much anymore but usually has a more cautious, observing expression on his face. Now he usually smiles when he's trying to provoke someone or is pleased that a plan went as planned. He also has a more reckless attitude when faced against other pirates that the World Government has labelled as a higher threat. For example, he casually asked X Drake how many people he had slain in his very first appearance, and had no qualms about flipping off Eustass Kid, the most wanted Supernova on the archipelago, even smiling defiantly when doing so.

However, he hates being ordered around, as evidenced of his frown and following reply when Kid told him and Monkey D. Luffy to stay back as he would hold off the attacking Marines. He is, however, capable of knowing when he and his immediate crew are in a pinch, and is not above resorting to forging brief alliances with rivals for survival. He speaks in a politely sarcastic manner. He appears to be honorable enough to refuse taking credit that is due to others. This is seen when he replied to Jean Bart that his gratitude is also deserved by Luffy when the former slave offered his gratitude to the pirate captain.

Law has displayed a more competitive side about him in the anime where he, along with Kid and Luffy, got into a childish argument about who gets to take down the marines stationed just outside the Human Auction House when the three Supernovas came out to confront them. Although, this might be because he was a little angry at Kid for trying to order him around, in contrast he does not seem as eager to reach the New World as the other Supernova crews, believe that One Piece will still be there regardless while the other crews fight amongst themselves, and that he needs to steal the throne properly. He then began an as-of-yet unseen mission to achieve Shichibukai status, and allow him much more freedom to do as he pleases in his journey through the New World on the way to One Piece.

Law also appears to have a sense of honor (or at least respect for those he sees as potential rivals in the future), which is seen when he appears at Marineford and claims he will help Luffy, because it would be too lame if his future enemy were to die. He was also appalled when he heard that Caesar subjected the kids on Punk Hazard to drugs.[10]  This is in stark contrast to what most people seemed to think about him, since Scratchmen Apoo claimed that Law was infamous for his cruelty, and one of Smoker's men claimed he cut out the hearts of one hundred pirates and sent them to the government in order to gain the position of Shichibukai.[2]  Law has displayed a cruel side, offering to strike Tashigi yet again after already vivisecting her body in half.[11]  He also suggested to leave the kids on Punk Hazard behind, as they were too much of a burden to deal with.

Abilities and Powers
'''Weaklings can't pick their way of death. '''

Law is a fearsome pirate who, along with most of his crew, proved resistant to Rayleigh's burst of Haki that took out almost everyone in the Auction house. Even Donquixote Doflamingo commented to his subordinates at Punk Hazard about Law's potential, comparing it to Luffy's, which Doflamingo witnessed himself during the war at Marineford two years ago; 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.

Trafalgar Law is shown to be a very crafty and opportunistic leader, even for a successful pirate captain and a former "Supernova"; despite being regarded as one of the most powerful pirates of his generation, Law was the only one of the group to voluntarily rest in the "Paradise" half of the Grand Line for at least a couple months, rather than immediately enter the treacherous New World region, indicating a great deal of caution and tactical mentality. He also demonstrated this by replacing a lot of the seastone chains on Punk Hazard with steel ones and came up with a plan to quickly and stealthily escapes from the cage he was trapped in. He was able to make a plan to retrieve the substance known as SAD, and his only miscalculation was Vergo, a man who was able to beguile the entire Marine organization, including the observant Smoker. He even managed to force Doflamingo, an extremely cunning and resourceful pirate in his own right, into a no-win scenario of either quitting the Shichibukai and face the wrath of theAdmirals or stay and face the wrath of Kaido.

Sometime during the timeskip, Law has become so powerful and infamous that even the ruthless Marines of G-5 were deeply afraid of him. He had gained a bounty that surpasses Luffy's current one, and then brought a hundred pirates' hearts to the World Government, earning him a position in the Shichibukai. Law was able to battle and eventually defeat Smoker, a Marine vice admiral and a Logia user without getting himself seriously injured. He also defeated Vergo in one move, while before in the past was unable to even harm him. He is now strong enough to counter an attack from an Admiral as shown with his confrontation with Issho and Doflamingo.

Physical Abilities
In addition to his Devil Fruit, Law has sufficient physical strength and tactical prowess to duel on equal terms against Smoker and his jitte. In addition, despite Caesar saying that the Yeti Cool Brothers are quite powerful, Law managed to dispatch one of them with relative ease. He has also displayed great 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 beating from Vergo which resulted in him becoming severely bloodied before defeating him in a single blow once Smoker had retrieved his heart.

Medical ExpertiseEdit
He has earned the nickname "Surgeon of Death" due to his surgical skills in addition to his formidable combat abilities. He appears to be considerably skilled as a doctor, as he was able to treat Luffy and Jinbe right after both of them barely escaped a murderous Akainu that left them on the brink of death. 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 fishmen 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, implying that he is also versed in pharmacology. The fact he was able to cure the children of Caesar's deadly NHC10 drug, though not completely, is a noteworthy feat, something Chopper was even amazed by.

Devil Fruit
Law is the user of a Devil Fruit called the Ope Ope no Mi,[7]  which allows him to create a spherical territory of light blue aura. In this territory, he is capable of separating and spatially displacing anything and everything inside (including himself), referred to as that he can "operate" on anything within the spherical "operating room". Easily among the most versatile Devil Fruits around, with his powers, Law is easily capable of causing mass havoc within the area he controls. He can also use it for teleportation purposes. He has also demonstrated being able to apply his ability for medical purposes, as seen when he cured the giant children from their addiction brought by Caesar's drugs.[24]

Law appears to have mastered his power to such a great extent, that he can even cut through someone who completely imbued their body in Haki.[25]

The weakness of the technique seems to be the concentration required to use it; Law must gesture with his hands to centralize the effects upon its victims, which can allow an opening for a fast enough opponent, such as Vergo. His abilities also depletes his strength the more he uses them.[26]  The full extent of this ability remains unknown at this time.[27]  Other than that, he has the same standard weaknesses as all Devil Fruit users.

Swordsmanship
Law's offensive abilities lie in his swordsmanship, demonstrated by his expert use of a sword about as tall as he is, though he is seen being able to defend himself without it by using his Devil Fruit abilities. 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. He can dismember people without harming them and attach separated parts in any manner he sees fit.

His proficiency is enough that he was able to clash against Smoker's Nanashaku Jitte with little trouble, and combined with his Devil Fruit powers he has repeatedly shown being able to mutilate people faster than they can react, apparently defeating Kin'emon in this manner. He also was able to quickly defeat Tashigi, a skilled swordswoman of the Marines, severing her sword in two, as well as taking down Scotch and his giant knife in one swift move.

His greatest swordsmanship feat shown so far was upon defeating Vergo, where the wake of his slash was capable of cutting apart Caesar's laboratory and the surrounding mountains and cutting a meteor in half.

Haki
Law is stated by Luffy to have Haki.[28]  The extent of his ability in using it has not been revealed, but as he asserted himself as one of the people capable of battling Caesar Clown, it is safe to assume that he can at least use Busoshoku Haki.

During his battle with Smoker, Law was shown capable of bypassing the vice-admiral's Logia defenses thanks to his own Haki powers.
