Shanks always wears a long black cape over his shoulders and until he met Luffy, wore a straw hat that he had worn for many years beforehand. He always wears trousers that are cut below the knee as well as a pair of sandals. The most striking thing about Shanks is the color of his red hair, of which his nick-name "Red Haired Shanks" comes from. He also has three scars across his left eye, which were given to him by Blackbeard a long time ago. He has a missing left arm, that he had lost when he saved Luffy from a Sea King. Shanks and his crew are almost always seen partying and drinking alcoholic beverages whenever they make an appearance as the Captain's favorite pastimes are attending and hosting parties and banquets. According to Oda, Shanks is the one character that resembles himself the most out of all the One Piece characters, because of his fun-loving partying nature.

Migi is the Parasite which lives in Shinichi's hand. Unlike "successful" Parasites, Migi has no desire to kill humans for sustenance, and is nourished by the food Shinichi eats. Migi is, like other Parasites, completely without emotion. His primary consideration is survival, and he has threatened (and in some cases attempted) to kill other humans who pose a threat to his and Shinichi's secrecy. When he and Shinichi were first coming to terms, he even threatened to remove Shinichi's other limbs in order to render him unable to place the two of them in danger. Migi can be reasoned with, however, and has just as much reason to be mistrustful of other Parasites as does Shinichi. On the other hand, unlike Shinichi, Migi has no inclination to place himself at risk in order to protect other humans from Parasites. (Source: Wikipedia)
