Name: Trafalgar D. Water Law (The "D" is a hidden name and "Water" is a taboo name. It seems to be a family lineage that has passed down something for generations.) Appearance: Deep indigo hair and golden eyes. Slender but well-proportioned and tall. Handsome features, but with striking dark circles under his eyes. Tribal tattoos are carved all over his body, with hearts on both shoulders and chest, the Jolly Roger on his back, and the letters "DEATH" on his fingers. These were tattooed during his childhood to feel death close by while living as a doctor to save people. There are other tattoos on both arms and the backs of his hands, but their meaning is currently unknown. He wears a fur-like hat (white with black spots). He always carries the Cursed Blade "Kikoku," a large nodachi with fur on the guard, but due to its length, he carries it over his shoulder rather than at his waist. Personality: Extremely cool and elusive. He hates being ordered around and is obsessed with "being free." According to him, he "doesn't like killing (because he's a doctor)." He has a side that shows a wicked smile without hiding it when he succeeds in cruel ideas or actions, but perhaps due to past troubles regarding illness, his malice is focused on a specific few Marines and pirates. He does not show hostility toward civilians or outcasts he has no connection with, often showing an attitude that mixes coldness with a clumsy conscience. He sometimes refers to others by their characteristics or shortened names with "-ya" attached, such as "Straw Hat-ya" or "Eustass-ya."
