On top of being one of twelve pirates who are referred to as "The Worst Generation" (formerly known as "The Eleven Supernovas”
Law is a slim man of a relatively tall height. He has faint shadows right under his yellow eyes.
and his mouth is usually seen in a smile. He has dark hair, a majority of which is obscured, save for his sideburns and small goatee by the northern-style fur hat that Law wears, which is white and has spots on the bottom and along the rim.
His hair color is depicted as black in both the anime and manga, though sometimes the manga depicts it as blue.
He has many tribal-style tattoos on his arms; on both of his hands, are letters spelled as D E A T H tattooed in black on each of the back of his fingers. Originally in the manga, his left thumb was not tattooed, with the letter A missing. Later on, all of his fingers were tattooed complete with all five letters.
As a child, Law had his fur hat and his faint shadows right under his eyes, but wore the uniform for the medical academy he was attending: a blue lab coat with a red tie, dark blue shorts and green shoes; he was holding a scalpel on his right hand and a frog on his left hand, since he was already in training to become a surgeon, with his father being his teacher.
Law lost his tie and lab coat, and his shirt underneath became more raggedly, and his shorts have white spots on them. Because of his heritage, he inherited the Amber Lead Syndrome that accumulated throughout the generations of Flevance, which left his skin white and pallid until he obtained his cure.
He now wears a yellow t-shirt similar in appearance to his old hoodie, with a black jacket over the shirt. On Punk Hazard, Law wears a long black coat with his crew's jolly roger along the hem and on the sleeve. On Dressrosa, he wears a black coat with a hood which features the word Corazon on the back.
Law was a very kind and devoted child, refusing to leave his family behind despite falsely promised evacuations at hand, and aspiring to become a great doctor like his father while happily going to festivals with his beloved family. Upon the destruction of his homeland, the annihilation of his classmates and family, and diagnosed with no more than thirty-eight months to live, Law suffered a mental breakdown and, according to Doflamingo, came to be known for being very cruel and cunning, having wanted to join Doflamingo's crew so he could destroy everything around him.
Only after having been cured of his illness by Corazon did Law have a change of heart.
