Zoro is a muscular man of average heZoro is a muscular man of average height with lightly tanned skin. He always carries his three swords along with him, bundled up with a green haramaki over his right hip, allowing him to easily draw them with his left hand.

Zoro has a stern, serious, and distanced personality, but unlike Robin, he often reacts in a goofy and exaggerated comic style due to his short-tempered and impatient attitude. On the ship, he normally either trains with weights or sleeps.
