Roronoa Zoro, also known as “Pirate Hunter” Zoro, is the combatant of the Straw Hat Pirates, one of their two swordsmen and one of the Senior Officers of the Straw Hat Grand Fleet. Formerly a bounty hunter, he is the second member of Luffy’s crew and the first to join it, doing so in the Romance Dawn Arc.

As a master of Three Sword Style, a swordsmanship style which he created during his childhood training in Shimotsuki Village, Zoro is among the three most powerful combatants of the Straw Hats, alongside Luffy and Sanji. His dream is to become the greatest swordsman in the world, in order to honor a promise he made to his deceased childhood friend Kuina.
