Kin'emon

The Samurai from Wano is an as yet unnamed Samurai from Wano Country whom the Straw Hat Pirates found in various pieces at Punk Hazard.

Appearance
The Samurai's appearance matches the stereo-type of all samurais found in ancient Japan, with a top-knot. He is quite tall, with his legs alone matching Monkey D. Luffy in height. He is also seen to be quite muscular, but not overly so.

Personality
The Samurai is revealed to be quite perverted, even though he has old-fashioned ideals. He seems to follow the way of the samurai, claiming he would commit suicide if he could, for the disgrace of being dismembered without dying. He still tries to maintain his pride, even though he's just a head. Though he seemed to be outraged at Nami's sense of fashion, he still greatly enjoyed ogling at her cleavage. He cares deeply for his son, Momonosuke, as he travelled to the dangerous Punk Hazard island and challenged a Shichibukai to find him. Even after being chopped to pieces, his torso and leg still attempted to look for his son, and attacked anything that got in the way. He also has an extremely rude special ability of talking with his farts.

Momonosuke
The Samurai seems to deeply care for his son, as shown when he travelled to Punk Hazard and challenged Trafalgar Law, a Shichibukai, to get him back

Pirates
He seems to strongly dislike pirates.

Straw Hat Pirates
Despite his strong dislike for pirates, and even though he initially scorned them when he found out that they were, he is starting to see that the Straw Hat Pirates are different from most others. However, despite knowing this, he is not willing to break his pride and ask for their help.

Trafalgar Law
The Samurai seems to curse the Shichibukai for the way he currently is.

Swordsmanship and Martial Arts Skills
Even after being dismembered and chopped up, the Samurai was capable of putting up a fight, with his legs recklessly attacking Luffy's party when they encountered him. His torso alone was able to match Brook in swordsmanship, utilizing a two-sword style.

Devil Fruit Ability
Using the ability of the unusual fruit he ate a long time ago, he is capable of creating clothing and disguises for anyone, including himself, if they put a leaf or stone on their head. This ability is dispelled if they were to remove the clothing.

Special Skill
After being dismembered, his legs were found by Luffy, Zoro, Usopp, and Robin. During this time, his legs seems to possess the ability to speak but after his leg part are reattached back to the head, it is revealed that he can speak from his legs using his farts which disgust the Straw Hat Pirates.

Meeting the Straw Hats One Piece at a Time
The samurai went to Punk Hazard to find his lost son. During the journey, he encountered Shichibukai Trafalgar Law. Law dismembered the samurai and his body parts are scattered all over the island. His legs got stuck on a dragon, his head is locked in a cell in Vegapunk's former research facility, and his torso and arms are wandering around the frozen side of the island, cutting down centaurs.

Trivia

 * His Devil Fruit ability to disguise people is similar to the shape-shifting abilities of the kitsune and tanuki of Japanese folklore. A common prerequisite for their transformation is that the animals must place reeds, a broad leaf, or a skull over their heads.
 * He is a very old fashioned Samurai warrior who expects women to follow the utter ideal tradition of walking 3 steps behind men and talking gracefully and quietly. He on many occasions referred to Nami as shameless, violent and obscene woman due to her careless behavior. It is yet not confirmed if this is the traditional code of Wano Country or if it is his personal expectations of women.
