Trafalgar D. Water Law

Trafalgar Law is the captain of the Heart pirates. He is one of eleven pirates who have been referred to as "The Eleven Supernovas" on Sabaody Archipelago whose bounties are higher than  100,000,000 when the Straw Hats arrive in the place.

Appearance
Law wears a shirt with a symbol that some believe saves similarity with Donquixote Doflamingo's Jolly Roger and the symbol seen at the Human Auction Grove.

Abilities and Powers
Law is a doctor whose skills have earned him the nickname of "Surgeon of Death". As for his weapon, he carries a Nodachi with a scabbard decorated with crosses from the opening to the bottom. With this sword, Law can swiftly cut objects from a distance; though it is not clear whether or not this is only applicable when both him and his target are within the range of the radius generated by his Devil Fruit powers. He, along with his crew (save for one who nearly collapsed) proved resistant to Rayleigh's burst of spirit energy that took out almost all in the Auction house

During an assault on the Human Auctioning House, Law revealed himself as holding a Devil Fruit power. His ability allowed him to create a spherical territory (not necessarily centered on his location but wide enough to cover several meters) where he can replace and switch any objects from their respective locations within it instantly at will, but presumably only if the two objects to be displaced are roughly of equal size. Using this ability, Law was able to make it seem like he sliced the head off a Marine, only to replace it with a cannonball that was being fired towards him. The Marine's head on the other hand, remained alive as it flew into Law's hand and could see the cannonball floating and exploding over his body. With the exception of Trafalgar himself, anything caught within the territory generated by his power also seems to lose momentum (similar to the efects of Foxy's Noro Noro Beam), causing it to move very slowly, as was seen at the cannonball fired at Law's direction which moved at a noticeably delayed pace after getting within the reach of Law's power. The identity of the ability remains unknown at this time.

History
Not much is currently known about him other than the fact that he appears to be very laidback (in a manner not unlike Shanks), as he was first seen sitting ontop of a crate as another pirate with a high bounty passed by, X Drake. He then asked how many did the latter slay. He is also unfailingly polite, usually referring to others as "Mr". This easy-going attitude of Law's not always predominant, having loss his cool after Captain Kid offered to rid the marines amassing outside the Auction House for him and the Straw Hat Crew

Later, after Eustass Kid mentioned that he is mannerless, Law replies by flipping his middle finger up. After Monkey D. Luffy attacked one of the World Nobles, Law had a short conversation with his fellow Supernova, who was more interested in the bear in his crew than he was in any ideas of conflict. After being insulted (alongside Luffy ) by Eustass Kid ,who said he will take care of the marines himself,he went out and began fighting the marines,alongside (though without particular liking in this match-up) Luffy and Kidd. He seemed to be more tolerant about Luffy than he did with Eustass though, despite also having been told by the Straw Hat to back off, saying that he (Luffy) doesn't need assistance from the two other Supernovas, whereas when told by Eustass to back off, Law replied that he'll be taking out Captain Kid first if he orders him around one more time
