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 earlier on. 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").
