He is seen wearing a black-sleeved and hooded yellow hoodie with his Jolly Roger out on the front of his chest and the sleeves rolled up. Law also sports a pair of jeans with odd markings on both the knee and ankle areas, similar to the ones on his hat, but darker in color, and a pair of dark, pointed shoes. He has a pair of small earrings on each ear.
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. He also has a black cross 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 simpler heart tattoo on his shoulders and his Jolly Roger tattooed on his back.
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. After escaping Flevance, 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.
In Oda's depiction of the Supernova post-timeskip, he seems to have lost the fur rim of his hat and replaced it with a thick bill, turning it into a rather spherical hat resembling a Wool Skipper. His goatee has become somewhat scruffier, and his right hand now also has the fingers tattooed. 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.
During his second confrontation with Doflamingo, Law's right arm was cut off. It is later reattached by Leo and healed by Mansherry.
During the Zou Arc, Law changed into a dark, short-sleeved shirt with a light-colored heart pattern on the lower left side. He also bears stitch marks on his right arm after it being reattached by Leo.
Law is the user of a Devil Fruit called the Ope Ope no Mi, which allows him to create a spherical territory of light blue aura. In this territory, he is capable of separating and spatially displacing anything and everything inside (including himself), referred to as that he can "operate" on anything within the spherical "operating room". Easily among the most versatile Devil Fruits around, with his powers, Law is easily capable of causing mass havoc within the area he controls. He can also use it for teleportation purposes. He has also demonstrated being able to apply his ability for medical purposes, as seen when he cured the giant children from their addiction brought by Caesar's drugs.
Law appears to have mastered his power to such a great extent, that he can even cut through someone who completely imbued their body in Haki.
The weakness of the technique seems to be the concentration required to use it; Law must gesture with his hands to centralize the effects upon its victims, which can allow an opening for a fast enough opponent, such as Vergo. His abilities also depletes his strength the more he uses them. And given Law's strategic nature, he seems to have a strong tendency to preserve every bit of his stamina in preparation before facing off against powerful adversaries, like the likes of Donquixote, as seen when he consistently refused to use his powers to aid his Straw Hat Allies as they make their way towards Green Bit. Other than that, he has the same standard weaknesses as all Devil Fruit users.
