Roronoa Zoro

Roronoa Zoro, also known as "Pirate Hunter" Zoro, is the swordsman of the Straw Hat Pirates and a former bounty hunter.

He was the first member to join the crew, and, to date, is considered the largest threat and most dangerous member in it 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 before he obtained his first bounty, while a few people believe him to be the first mate.

He is one of the top four fighters in the crew alongside Luffy, Sanji, and Jinbe, and his dream is to become the greatest swordsman in the world. Zoro is also regarded as one of twelve pirates who are referred to as the "Worst Generation" (formerly known as the "Eleven Supernovas"). He currently has a bounty of 320,000,000.
