Trafalgar Law, alias "Surgeon of Death", is both the doctor and the captain of his crew, the Heart Pirates, a pirate crew from the North Blue. Over the course of his time as a pirate, known for his criminal and devious actions, he's acquired a rather high bounty for his head.

 

The outlaw sails via golden submarine with the rest of his crewmates rather than the typical surfacing ship, making him difficult to be pin-pointed and located by the Government. With the appearance of a submarine, it still works very much like a ship with the consideration that it has fully functional masts. Along the side, the "Smiley" styled Jollyroger is stamped, the word "DEATH" printed to accompany it as a referral to the tattoos on Law's hands along with his alias "Surgeon of Death". Even though it's a pirate's vessel, the inside is stocked full of medical supplies and even various systems of life support.

 

Unlike most pirates from the North Blue, the Heart Pirates do not use a skull and crossbone, but rather a smiling--perhaps grinning face. It six has protrusions going in neat and various directions. Looking extremely similar to the Donquixote Pirate's flag, only just without the cancel slash in the middle.
