Zoro is one of the main characters in One Piece and certainly one that fans hold incredibly close to their hearts. Being the first person that Luffy recruited on his crew, Zoro has always been pivotal for the main story to move forward. Of course, Zoro being a combatant meant that strength was an important part of his character, and he has only gotten stronger over time. This is expected of him, given that he wants to become the World's Strongest Swordsman.
