Trafalgar D. Water Law

Law is a pirate from the North Blue and the captain and doctor of the Heart Pirates. He is one of the twelve pirates who are referred to as the "Worst Generation". He became one of the Seven Warlords of the Sea, but was later revoked for allying with the Straw Hat Pirates. Law's dream is the find the One Piece, but also desires to know the purpose of the Will of D.

Law is the only known survivor of Flevance, a town whose inhabitants suffered from a condition known as Amber Lead Syndrome. Because the disease was fatal and poorly understood, Flevance was destroyed by neighboring countries out of fear - including Law's parents and his younger sister, with a young Law barely escaping alive. He subsequently joined the Donquixote Pirates, where Donquixote Doflamingo intended to make Law one of his executive officers. However, thanks to the efforts of Doflamingo's brother, Rosinante, Law was freed from the Donquixote Pirates' influence and became a pirate set to bring down Doflamingo's empire. Even though Rosinante gave his life to ensure a young Law escaped from Doflamingo's clutches, Law himself set out to finish what his mentor had started with a plan of his own, becoming obsessed with the idea of taking Doflamingo down personally.

Law is a slim and tall young man with a height of 6'3, aged 26. His birthday is October 6th. Law has grey eyes, and his face is usually seen with a smirk. He wears a northern-style fur hat, which is white and has a spotted pattern along the bottom and the bill. He has short dark hair, a majority of which is obscured by his hat, save for his sideburns and a small goatee. Law has many tribal-style tattoos on his arms; on both of his hands are the letters spelled D.E.A.T.H. tattooed in black. He also has a black cross-like tattoo on the back of both of his hands. On his chest, he has a tribal-style heart tattoo with his Jolly Roger on it. He has a simpler heart tattoo on his shoulders and his Jolly Roger tattooed on his back.

Law is an extremely laid-back yet scheming man. Not eager to directly clash with potential enemies, Law prefers to be patient and only act when the time is right, choosing to stay out of unnecessary conflict and wait for a valuable opportunity to further his goals. Also, while Law does not like starting or being involved in commotions that may attract unwanted attention towards himself, he enjoys spectating the chaos initiated by others. Law does not smile as much anymore, 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. Law has a bolder attitude when faced against other infamous pirates, especially his peers from the Worst Generation. Reflecting this boldness, Law self-admittedly hates being ordered around; but 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. Law remains incredibly hardened by his tragic past in his adulthood, leading to several rumors that present him as a cold and heartless man. Law is very blunt when responding to people and usually does not bother himself with excuses or apologies for his words and actions. Despite Law's terse and rather unkind demeanor towards others, he still retains strong compassion and kindness (even if reluctantly), which he originally had as a boy, while regaining them due to Rosinante's influence.

In battle, Law is sarcastically merciful, using his powers to mutilate his enemies without fatally harming them, before toying around with their bodies in a mocking fashion. Law is a doctor and dedicated to saving lives, thus he avoids employing lethal force and abhors the idea of needless murder. Despite being a Devil Fruit user, Law is a master swordsman, thus carrying a katana with him.

The Polar Tang, submarine ship of Captain Trafalgar and the Heart Pirates, sailed on the surface of the ocean due to the nice weather rather than using the sub portion of their ship, allowing the crew a moment in the warm sun. The deck was alive with the Heart Pirates chatting amongst themselves and working, and the air was fresh and salty.
