Roronoa Zoro (ロロノア・ゾロ, "Roronoa Zolo" in several versions), named after François l'Olonnais, nicknamed Pirate Hunter Zolo (海賊狩りのゾロ, Kaizoku-Gari no Zoro) is Luffy's right hand and first mate of the Straw Hat Pirates. He is a skilled swordsman who uses up to three swords at once, clutching the third in his mouth. To fulfill a promise he made to a childhood friend named Kuina, he wants to become the world's greatest swordsman by defeating Mihawk. Before joining Luffy, he made a living by bounty hunting. He joins Luffy's crew in exchange for his aid in escaping execution. He makes it clear that he would turn on his captain if he ever stepped between him and his dream, but unknown to Luffy, Zolo thinks that if he cannot protect Luffy's dream, his own would have no meaning and is even willing to die for it. His physical strength is enough to lift a building. During a fight with Baroque Works agent Daz Bones or Mr. 1, he learns how to cut through solid steel. He can employ an "Asura" technique which gives him three faces and six arms, thus totaling nine swords. In addition, Zolo can expand the muscle mass of his arms. He is extremely poor at understanding geographical directions and gets lost very easily. He also sleeps a great deal and loves to drink. His hair colour is green.
