Roronoa Zoro

Roronoa Zoro, also known as "Pirate Hunter" Zoro, is a pirate and a former bounty hunter. He was the first member to join the Straw Hat Pirates, and, to date, is considered the largest threat and most dangerous member in the crew after Luffy. His fame as a master swordsman and his great strength, along with the actions of his captain, sometimes led others to believe he was the true captain of the crew. He is one of the top three fighters in the crew alongside Luffy and Sanji, and his dream is to become the greatest swordsman in the world. Zoro is regarded as one of twelve pirates who are referred to as the "Worst Generation" (formerly known as the "Eleven Supernovas").

Zoro is a muscular young man with lightly tanned skin. He always carries his three swords along with him, bundled up with a green haramaki over his right hip, allowing him to easily draw them with his left hand. Of the three swords he has on his person, he has always been seen carrying the Wado Ichimonji, while his other two swords have varied over time due to them being destroyed and subsequently replaced with progressively better ones. Although his right hand is usually seen resting over them, he can also use this hand to pull his swords out before sitting down.

He has three identical gold earrings on his left earlobe. Zoro normally keeps a black bandanna tied around his left bicep and ties it around his head when he is fighting seriously against an opponent. Zoro's body is covered with scars from his many battles, most notably the massive scar stretching from his left shoulder to his right hip that he acquired during his loss against the world's greatest swordsman, Dracule Mihawk, at Baratie. His other visible scars are the scars he inflicted upon his ankles in a desperate attempt to free himself from Mr. 3's Giant Candle Service Set by trying to cut his feet off at Little Garden. After the timeskip, he gained another scar over his left eye, obtained through unknown means. Zoro's other remarkable feature is his cropped green hair, which Sanji often teases him about by calling him "marimo" (moss-ball, moss-head in the Viz Manga and FUNimation dub) due to its resemblance to one.
