Trafalgar Law is a character from the anime/manga One Piece, a notorious pirate rookie in the Worst Generation and former Shichibukai. He's the last survivor of Flevance in North Blue and captain of the Heart Pirates, known as the 'Surgeon of Death'.
Law is a thin young man with tanned skin and short dark hair. He has tattoos on his arms and his chest. He also has the letters D,E,A,T, and H tattooed on his right fingers, spelling Death. Law wears a yellow shirt and a blue cloak with fluffy fur collar. He wears the traditional Northern hat, but his has an animal print on it, along with his jeans. He has light shadows under both of is eyes. He also wears piercings on both of his ears.
Law is a smart and calculative man. He is patient and waits for his moment to strike. Law does not smile as much, displaying a more cautious, observing expression on his face. In fact, he tends to only smirk when feeling pleased that a plan went as intended or while attempting to provoke an enemy. That being said, Law has a bolder attitude when faced against other infamous pirates, especially his peers from the Worst Generation. For example, he casually asked X Drake how many people he had slain in his very first appearance and had no qualms about rudely gesturing to Eustass Kid, the most wanted rookie pirate on the Sabaody Archipelago who had a reputation for killing people for the most minor of reasons, even smiling defiantly when doing so. Law has also done this same gesture towards Donquixote Doflamingo both to provoke and display his contempt for his former captain, despite being close to death and threatened at gunpoint at the time. Reflecting this boldness, Law self-admittedly hates being ordered around; however, he is reasonable enough to understand when his immediate crew and are in a pinch, not being above resorting to brief alliances with rivals if it meant survival. Surprisingly, belying his usual cool attitude, Law can be quite prideful and even childishly competitive, particularly when next to Luffy and Kid. He also appears to dislike bread.
Law is the user of a Devil Fruit called the Ope Ope no Mi 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. 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. 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.
Law was born in the country of Flevance in the North Blue, which was known the "White City" for the color of the Amber Lead that was mined there. He lived there with his parents, who were doctors and were likewise training him, and his younger sister. Law's childhood coincided with the time when the symptoms of Amber Lead poisoning were at their peak within the country, and he was doomed to die before reaching adulthood. The kingdom was at war with neighboring countries who mistakenly believed that the disease was contagious. The World Government and the royal family knew about the sickness beforehand but did not disclose this information to the public, even when the symptoms were becoming more noticeable. His parents were doing all they could to help the people but couldn't do much without proper supplies. What's more, Law's sister, who was in an advanced stage of the disease, was slowly dying. A local nun was collecting children to be taken off the island during the war and offered Law to come with her. He declined as he didn't want to leave his sister behind, but the nun promised to come back for him. However, an extermination crew shot his parents before his very eyes. The nun and his friends were likewise killed in the raid and his parents' hospital was burned down with his sister inside during the destruction of the country. An emotionally wrecked Law managed to escape the quarantine by hiding under dead bodies being shipped outside the city. Having lost everything and a wrong levied against everyone dear to him, Law became nihilistic and omnicidal, wishing to destroy as much of the world as he could without believing in anything anymore.
From there he arrived at a port town, Spider Miles, he approached the Donquixote Pirates and asked Doflamingo to let him join while strapping himself with bombs. With the time he had, Law wanted to destroy as much as he could. While speaking with Trébol and Diamante, Law explained that he had around three years to live and reminded them what his goals were. Afterwards, Law met Corazon and showed indifference to his clumsiness. Shortly after Law was informed that Corazon hated kids, the executive threw Law out the window. Law, having survived the fall, was angered at being treated this way out of the blue and swore to kill him. He watched impassively as Corazon burned himself after accidentally setting his feathery mantle ablaze while lighting a cigarette.
At a pizza feast, Lao G told Law about the crew's blood law and Doflamingo warned him not to lay a hand on Corazon. The crew then discovered that Law was sick with the Amber Lead Disease, and Jora incorrectly thought that the disease was contagious, at which Doflamingo corrected her. Doflamingo then questioned Law if there were any other survivors. Law answered that he did not know and revealed that he escaped the extermination of Flevance by hiding in a pile of corpses, causing Gladius to gag. Law then declared that he no longer believed in anything and that he will have his revenge on Corazon. Baby 5 slapped him on the head and warned him about the consequences, which included torture. Law merely glared at Baby 5, causing her to cry. Later on, while most of the crew was out raiding and discussing on Law's past, Law snuck up on Corazon while he was alone and stabbed him from behind. However, he was seen by Buffalo, who was shocked at seeing Law breaking the crew's blood law. To get away with it, Law bribed Buffalo with ice cream.
However, Law was still a bit uneasy about Buffalo's trustworthiness, so he attempted to flee only be to caught by Jora and Machvise who brought him to Doflamingo. Law than noticed that Corazon was not dead and believed that he had informed his brother that he (Law) had impaled him. Doflamingo announced that he had decided to officially welcome Law into the Donquixote Pirates. Law was shocked that Corazon did not simply write something up to tell Doflamingo about what had happened.
Law reminded Doflamingo that he would die in less than three years, but Doflamingo went on to explain that their "family" dealt with underworld businesses and told Law of a possibility for survival: obtaining a Devil Fruit power that could heal him. He further explained that if Law was lucky to find one before his life expired, he would raise and train him to be his right-hand man in ten years. Doflamingo later noticed Corazon's wound and Corazon informed him that he was attacked by an enemy.
Down the next roughly two year, Doflamingo explained his plans as they traveled and committed acts of piracy while Law was being annoyed by Corazon's constant clumsiness and falling for practical jokes. The Donquixote Pirates would loot, attack, make business deals, fight and toast during their time together. Law was tutored under Doflamingo himself, while the rest of the family also trained him: Lao G in Martial arts, Gladius in gunnery, and Diamante in swordsmanship.
Eventually, the time came when Law only had a year or less left to live. Baby 5 noticed how the white spots had increased. Baby 5 and Buffalo told Law their real names and asked Law to reveal his. Buffalo even threatened to reveal what Law did to Corazon two years prior. Law then told them his full name, Trafalgar D. Water Law. He explained that the "D." was supposed to be a secret and Water was his true name. Baby 5 found the name boring, causing Law to lash out at her. Suddenly, Law was picked up and carried away by Corazon.
When at a safe distance, Corazon, speaking for the first time, asked if that was really his full name. Corazon then explained that if he was really a "D.", he should leave the crew right away and warned him not to go anywhere near Doflamingo.
Sometime after joining the crew, he became acquainted with Vergo. At some point he formed the Heart Pirates and ate the Ope Ope no Mi, the latter act angering Doflamingo as he never intended for Law to eat it. Although Law was meant to die at age 13 from Amber Lead Syndrome, he was somehow cured, and continued to live on.
Eleven years before the main storyline began, Doflamingo killed his own brother and then-head of the Donquixote Family, Corazon. As he was Law's benefactor, Law has wanted nothing more than to see him die since.
At some point he was severely beaten by Vergo. Doflamingo surmised the incident had left some form of trauma on Law.
Along with his crew they fought their way through the Grand Line and eventually reached the Sabaody Archipelago.
Law tends to become either appalled or deadpan whenever the Straw Hats engage in their usual carefree antics. Usually cool and collected, despite his best efforts to keep them focused on their mutual goals, Law has occasionally been drawn into their nonchalant "pace" and was shocked when he realized it. However, Law thinks highly of the Straw Hat Pirates, stating that they were a group capable of performing miracles. Nami once stated that Law was almost as reckless as Luffy, doing whatever he wanted and never listening to anybody.
Law doesn't refer to some of them by their names. He either uses their epithet, such as calling Luffy "Strawhat-ya" or Sanji "Blackleg-ya", or by using his own made-up nicknames, such as calling Usopp "Nose-ya", Franky "Robo-ya", and Brook "Bone-ya". He does, however, refer to Zoro and Nami by their given names, calling them Zoro-ya and Nami-ya, and Chopper and Robin by their surnames, calling them Tony-ya and Nico-ya.
