Roronoa Zoro

Zoro has devoted his life to becoming the world's strongest swordsman. Even before joining the crew, he was well-renowned for his outstanding abilities and accomplishments in battle. His skills drastically improved after becoming the combatant of the Straw Hat Pirates and entering a two-year training period under the "Strongest Swordsman in the World", Dracule Mihawk. By the time he met Luffy, Zoro had established himself as a fearsome bounty hunter in the East Blue, so much so that Koby had heard he was a "demon in the form of a man". His accomplishments in hunting pirates were significant enough to earn him the epithet of "Pirate Hunter", which he remains known for even after becoming a pirate. After his crushing loss to Dracule Mihawk, he vowed never to lose again. Since joining the crew, Zoro has defeated several mighty adversaries.

 
Alongside Luffy and Sanji, Zoro is considered one of the Monster Trio of the Straw Hats due to his strength. Zoro's infamy has frequently been treated as second only to his captain, and in some instances, he has even been mistaken as the leader of the Straw Hats due to his more extensive reputation; onlookers have also wondered how he could not be the captain after seeing demonstrations of his power. During the crew's journey, Zoro has come to possess some of the most legendary swords in history and has used them to both improve his skills and develop the most devastating attacks.

Zoro was the second Straw Hat to receive a bounty, and for much of the crew's existence, his bounty has been the second highest. Zoro was identified as a Super Rookie after obtaining a bounty of over 100,000,000 beli before reaching the Sabaody Archipelago; he was only one of two non-pirate captains (alongside Killer) of the Worst Generation to have that distinction.

Weaker people are easily intimidated by Zoro, as Koby remarked that he had a "demonic aura" at Shells Town even as he was tied up and starved of food for over a week. This ability has held even in the New World, as when Monet came to suddenly realize the degree of power and killing intent Zoro had, she froze in place as Zoro charged her. After Zoro intentionally performed a harmless attack, she then became seized by fear to such a degree that she was unable to reform her Logia body to its normal state. When Zoro gets serious in a battle, he usually dons his black bandanna on his head, though whether or not it has any real psychological effect on his abilities is uncertain.

Ever since entering the New World, he has rarely been wounded or given a serious challenge, defeating Monet with his sheer strength alone without Haki, frightening her to the point of being unable to control her elemental form. His first genuine challenge was a short confrontation with one of the Admirals, Fujitora, who described his slash attack as ferocious despite being held down by gravitational force. As the first showcase of his greatly improved strength and skills, Zoro defeated Pica, one of the Warlord Donquixote Doflamingo's top three elite officers, in a couple of moves after slicing apart his colossal stone body and figuring out the nature of his Devil Fruit abilities.

Zoro suffered his first serious wound in Wano against Kamazo the Manslayer, albeit because he avoided a surprise assault from Gyukimaru, while still managing to defeat the assassin using a single attack (without Shusui at the time). During the Raid on Onigashima, he faced off against the Emperor Kaidou, famed as the world's Strongest Creature, in both his beast and hybrid forms; wounding him despite the tremendous toughness of his body, then giving him his second scar since Kozuki Oden, earning his acknowledgment. In his battle against King, Kaidou's right-hand man and the Beasts Pirates' head All-Star, Zoro was able to apply advanced Haoshoku Haki and Busoshoku Haki to his three swords, dealing significant damage to and then defeating the exceedingly resilient lunarian despite being gravely wounded and close to exhaustion, whereas the former was closer to top condition. Due to these events, his bounty was raised to 1,111,000,000 Beli; the second highest among the Straw Hat Pirates, ranking just below his captain, Monkey D. Luffy, who was recognized as an Emperor.
