Roronoa Zoro (ロロノア・ゾロ?, spelled as "Corona Zolo" or "Roronoa Zorro" in some English adaptations), also known "Pirate Hunter Zoro" Zoro (海賊狩りのゾロ Kaizoku-Gari no Zoro?), is a fictional character in the One Piece. He was a pirate and a former bounty hunter.
He is one of the two swordsmen of the Straw Hat Pirates, the other being Brook. In the story, Zoro is the first to join Monkey D. Luffy after he is saved from being executed at the Marine Base. As a native to the East Blue, he came from the town known as Shimotsuki, where he trained in a dojo. He is an expert swordsman who uses three swords for his Santōryū (Three Sword Style), but is also capable of the one and two-sword styles(Ittoryu and Nitoryuu). He seems to be more comfortable and powerful using three swords, but he also uses one sword or two swords against weaker enemies. He usually keeps his Wadou Ichimonji on his mouth when he performs santoryuu. Before fighting Ryuuma he used to use his Wado Ichimonji as his first choice for one sword style but after the fight and especially after the two-year timeskip, he uses the black sword Shusui as his first choice of his one sword style.
His fame as a master swordsman and his great strength, along with the actions of his captain, sometimes led others to believe he was the true captain of the crew. He is one of the best three fighters in the crew alongside Luffy and Sanji, and his dream is to become the greatest swordsman in the one piece world. Zoro also inclueded as one of twelve pirates who are referred to as "The Worst Generation" (formerly known as "The Eleven Supernovas".
Zoro is a muscular young man 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. Of the three swords he has on his person, he has always been seen carrying the Wado Ichimonji, while his other two swords have varied over time due to them being destroyed and subsequently replaced with progressively better ones. Although his right hand is usually seen resting over them, he can also use this hand to pull his swords out before sitting down. He has three identical gold earrings on his left earlobe. Zoro normally keeps a black bandanna tied around his left bicep and ties it around his head when he is fighting seriously against an opponent.
Zoro is confident, but often acts in a very comical manner. He also has a terrible sense of direction which he is very insecure about since he never admits it when he gets lost, instead he always blames someone else. While the crew is out at sea, Zoro can be found (usually) sleeping or training towards his goal of becoming the world's best swordsman. He and Sanji have a great rivalry, often resorting to fighting (both verbally and physically) over issues from minor to extreme.
Zoro often also reminds others of the harsh facts, which often shocks some of the other crew members, although they usually decide he is right. Zoro is an atheist, because he stated that he does not pray to any god, and has never believed in anything except himself. Even so, Zoro knows that he still has a lot of untapped potential, and is constantly seen training and trying to improve his fighting skills. He also adheres to a strict sword master's code of honor, and never falsely brags or lies about his abilities, sometimes outright admitting a weakness, even to an enemy. He also never tries to escape from a fight or use trickery to win, believing that doing so is cowardly and scorning anyone who uses such tactics. Zoro is very vigorous, strong-willed, and determined.
He has a strong sense of leadership and reasoning. While technically not a samurai, Zoro maintains Bushido to a certain degree (e.g. he consistently refuses to attack an adversary whose back is turned, the only exception being when his friends are in imminent danger of losing their lives in which Zoro would strike the attacker from behind, and Zoro himself considers a scar on the back to be a swordsman's greatest shame). Whether he agrees with them or not, he will stand by Luffy's decisions, stepping in only to point out the seriousness of a situation where it has been overlooked by his crewmates (most notably when they wanted to bring Usopp back into the crew after Usopp challenged Luffy to a duel over the Going Merry and lost, even willing to quit the crew himself if Luffy just brushed the incident off because it betrayed his strong values in loyalty).
Zoro is very proud of the reputation he has built for himself both as a swordsman and as "The Pirate Hunter", starting with his Beli60,000,000 bounty which has quintupled since then. He also enjoys the fact that he has a higher bounty than Sanji. During the assault on Enies Lobby, one of the Marines referred to Zoro as "Luffy's underling" much to the delight of Sanji, who quickly became infuriated when Zoro pointed out that Sanji's lack of notoriety puts him below Zoro in status. Since then, once in a while to anger Sanji, Zoro will refer to him as "Pirate A". More recently he has been calling Sanji "#7", referring to his order of arrival at Sabaody. However, in spite of his personal pride and self-respect, Zoro has shown to be willing to lower himself to the ground in complete humility for the sake of his friends, as was seen when he begged Bartholomew Kuma to spare Luffy's life in exchange for his own (Zoro's). And then again when he shamelessly bowed before Dracule Mihawk, begging the Shichibukai who is his enemy, to train him in the ways of the sword.
Unarguably an extremely powerful and strong young fighter with immense potential, Zoro is one of the Straw Hat Pirates' top three fighters, and his strength is considered so great that, when taking his stern personality into account, people occasionally mistake him as the captain of the Straw Hat Crew after witnessing his skills in battle. While Luffy always fights the strongest enemy, Zoro usually fights the second strongest enemy. Although Zoro and Sanji would usually let their rivalry impede their fighting performances, they have proven to be a near-unstoppable force if they agree to cooperate for the battle, as seen when they instantly turned the tables against the Groggy Monsters.
