Roronoa Zoro (ロロノア・ゾロ?, named after François l'Olonnais)

 is a swordsman who uses up to three swords simultaneously, holding one in each hand and a third in his mouth, he aims to replace "Hawk Eyes" Mihawk as the world's greatest swordsman. Traveling the seas in search of Mihawk and making a living as a bounty hunter, he becomes infamously known as "Pirate Hunter" Zoro, while Helmeppo plots to have him killed. Zoro is saved from execution by Luffy in exchange for becoming his first crewman.
