Zoro

Roronoa Zoro, is a pirate and former bounty hunter. He is the second member of the Straw Hat Pirates and the first to join. He is also a master swordsman. Despite no clear role being given to him, Zoro is sometimes labeled by fans as the second-in-command of the pirate crew (the First Mate). Partially due to the fact that in the series, several captains refer to their first mate as their "Partners" or "Champions" and Luffy refers to Zoro by these earlier on in the series. Zoro is currently one of eleven pirates who have been referred to as "The Eleven Supernovas". He and Killer are the only supernovas who are not captains, they are also probably the only Supernovas not to have a Devil Fruit and they both rely on blade based weapons.

Zoro is a muscular man. He is almost always seen carrying around his three swords, usually bundled up with his green sash (or haramaki) over his right hip, which is favorable so he could easily draw any one of them with his left hand; his right hand is usually seen resting over the swords. This may indicate that he is left-handed or even ambidextrous, for most sword wielding characters in the One Piece Universe wear their swords on the left. On his left ear he wears three earrings and he normally has a bandanna tied around his left arm that he ties around his head when he is fighting seriously. The rest of his clothes vary from time to time; however, he usually wears a white shirt, dark green trousers, black shoes and the green haramaki sash around his waist.

His body is covered with scars from his many battles- during the Baratie Arc he lost a duel with the world's greatest swordsman, Mihawk, and was left with a massive scar across his torso. In the Little Garden Arc he tried to free himself from a wax prison by cutting off his feet. Although he did not entirely succeed, he gave himself a scar around each ankle. These scars are marked by black stitches

His other remarkable feature is his green hair, which Sanji often teases him about, calling him 'marimo' (moss-ball, moss-head in the Viz Manga and FUNimation dub).

According to Oda, Zoro resembles a shark.Oda uses the color green to represent Zoro, and he smells of steel.

Zoro usually maintains a stern, serious and distanced personality, but often loses his temper in a goofy and exaggerated comic style. He has a strong sense of reason when it comes to actual leadership of the crew and will often point out the seriousness of situations (such as Usopp's leaving the crew). And while technically not a samurai, Zoro maintains Bushido to a certain degree (i.e. he consistently refuses to attack an adversary whose back is turned on him, and neither does he tolerate getting assaulted from behind himself except when his crew mate is really in dire situation of dying of from an enemy threat, such as Kuma trying to take Luffy away, Zoro silently attacked him with Shishi Sonson) and is constantly mistaken for one. Whether he agrees with them or not, he will stand by Luffy's decisions, stepping in only to voice an opinion when the others have failed to see the true reality of a situation (again, such as Usopp rejoining the crew). He, like Luffy, has a lousy sense of direction (possibly even worse than Luffy's, since he usually assumes the others have gotten lost, and not the other way around). He is teased often because of it.

When the crew sails from one island to another, he normally either trains with weights or just sleeps and is normally awakened in a rather violent way by either Nami, Sanji and (accidentally) Luffy. His only apparent job on-board the Going Merry was using his enormous strength to haul up the anchor. Aboard the Thousand Sunny, however, he has been shown to seemingly spend most his time in the Crow's Nest (which is also a gym), so it is possible that he was designated as the ship's lookout. He also likes sake, almost to the degree that Luffy likes meat, but like Nami, he mostly never gets drunk due to his inhumanly-high tolerance for alcohol. He is sometimes prone to using serious methods for solving simple problems such as separating him and Usopp from cuffs by suggesting to cut off a hand, and cutting off his feet to get himself unstuck from some wax.

Zoro can also be very vigorous and won't back down when he is determined to achieve a goal or defeat an enemy. The risks that Zoro will often take to reach his dream of becoming the best swordsman often leaves others wondering if he is crazy. As far as Zoro is concerned though, only he has the right to call himself "Crazy". However, he is not one who stubbornly refuses utter defeat, especially if it all seems so inevitable. When Zoro has the intention to fight seriously, he normally ties his black bandanna(which is usually tied around his left upper arm) over his head. Furthermore, like any great warrior, Zoro is one who lives for the thrill of combat; in fact, he has a habit of showing a joyful smile whenever he faces a particularly skilled opponent, which often unnerves both ally and foe alike.

Also, Zoro can provide important and logical decisions at critical times by evaluating the situation, as he did when the crew wanted to bring back Usopp in the Enies Lobby arc. Zoro is the one who mentioned that Usopp is at fault for leaving the crew on his own accord, and Luffy shouldn't take him back unless he apologizes for his mistake.

He also is one of the first Straw Hat members to suggest killing someone or threatening to kill someone.

Zoro trusts Luffy implicitly, and always goes for his decisions whatever the consequences, acknowledging it as a captain's decision, which a crew must carry out without questioning. Zoro likes to compete with Sanji and they often get into fights over petty matters, often at inopportune moments. However, when the pair fight together against a common foe, they're a nearly unstoppable team. Despite their comical fights and rivalry, they have a brotherly trust and care between them they`d never admit to. Both Usopp and Chopper are in total awe of his strength and 'tough-guy' attitude. He also appears to have a close relationship with Chopper, seeing as the youngest crew member runs to him when he is scared or in danger, and the swordsmen is the first one to jump into action whenever Chopper falls in the water. Owing to his simple, direct nature, he is often exploited by the more cunning Nami, particularly in financial matters. After Arabasta, when Robin joins the crew, Zoro didn't trust her, but later does. Since Brook's entrance into the crew, he and Zoro have a sort of respect towards one another perhaps for both being swordsmen.

Before the storyline, Zoro had traveled around with two training partners, Johnny and Yosaku whom called him "Aniki" (older brother). He seemed to share a good relationship with them as a group of traveling bounty hunters. When they last saw each other, Zoro parted with them on good terms; however, they acknowledge that as a criminal they cannot be seen with him.

He was also child-hood friends with Kuina. He never beat her but, after they made a promise, she died. He holds his vow to Kuina dearly and whenever he comes close to defeat (such as the events with Morgan and Mihawk), he recalls her memory and his promise to spur him on.

He lacks Luffy's trust in others, thus he is often overly cautious when dealing with certain people. But usually, he will resort to intimidation when it comes to most situations, causing others (usually people much weaker than him) to react with complete fear. Zoro has a habit of making many more enemies wherever the crew ventures when compared to any other Straw Hat.

Zoro has a unique relationship with Ensign Tashigi of the Marines. Tashigi and Zoro met in Loguetown, where she helped him search for a new katana. Zoro defeated her once when she attacked him after finding out that he was a pirate, but refused to fight her again in later confrontations due to her uncanny resemblance to his childhood friend, Kuina. So far, whenever he has seen her, he has run away claiming that she is the one person he cannot fight.

During his journey, Zoro has also made or met many rival swordsmen such as Mihawk, Hatchan, Mr. 1, Priest Ohm, Kaku and Samurai Ryuuma.

Zoro is considered to be one of the Straw Hat crew's top three fighters; so much that people occasionally mistake him as the captain of the Straw Hat Crew after witnessing his fighting skills in battle. Mainly, while Luffy always fights the most powerful enemy, Zoro always fights the second strongest. Even without his swords, he has monstrous strength. He is able to toss an entire building at an opponent and even able to deflect Oars' punch singlehandedly. He can use some sword techniques without his swords. Zoro has shown to pack powerful punches. He even developed the ability to pump his arms up with pure muscle.

Zoro is unarguably one of the strongest characters revealed thus far. While most super powered pirates and villains gain power from eating one of the Devil Fruits, Zoro has gained his powers through hard work and training. Zoro has enough power in his lower body to allow him to keep up at a running pace with Sanji, who is a master of his own Leg-based style. He can also move at near-inconceivable speeds and jump astonishing heights. He can even dodge bullets with ease. He has been known to effectively knock out much larger creatures with unarmed strikes. Zoro also defeats opponents with massive punches and kicks. Also, during his fight with Kaku, he used an ability that gave him seemingly god-like powers. What this ability was, and how he attained it, are still unclear, but it was powerful enough to make numerous holes in the ground, as well as defeating Kaku. In Enies Lobby Arc, the Franky Family and Galley-La carpenters noted twice that Zoro was strong enough to be the captain of the group.

To match his strength, Zoro also has ridiculous amounts of stamina and endurance. Some of the things Zoro has endured include Mr.1's two buzzsaws jamming into his chest during the Arabasta arc, Arlong's saw-like nose stabbing into his face, Mihawk's Black Sword slashing his chest, CP9's Kaku's many Rankyaku attacks, and Kuma's Ursus Shock. Zoro managed to stay conscious while everyone else was incapacitated. Zoro then convinced the Shichibukai to transfer all of Luffy's pain and fatigue into him. Kuma was confident Zoro wouldn't live. However, the swordsman was seen standing blood-drenched at the end of the chapter/episode, claiming that nothing happened.

During almost all of his major battles, Zoro is usually seen covered with blood at the end (Oda has stated that Zoro lost 5 liters of blood fighting Hachi and Arlong at Arlong Park [It should also be noted that the human body holds about 8 liters of blood]). Zoro's agility, speed, and overall reflexes are also extraordinary. In numerous occasions, Zoro has shown being able to evade (or block) high-speed attacks and projectiles. These high-speed attacks and projectiles move so fast that it would normally be impossible for an average human to even notice them, much less evade them.

A running gag throughout the series is that while he is very perceptive during battle (as well as out), his sense of direction is extremely poor, to the point of getting lost on a straight path. This is often the result of Zoro not understanding directions. In the Arabasta Arc, he mistakes going north for going up. In the Drum Island Arc, he believes that he can keep the ship on course by heading toward a large cloud (which can move and change shape). He is unaware of his lack of direction. Everytime he gets lost, he mutters "the others are lost again". This is further made fun of with Jigoro in Thriller Bark. Jigoro had Zoro's shadow implanted in him. While the Zombie Generals were heading to help, he goes in the opposite direction. However, Zoro has other strong senses and is often one of the first members of the crew to hear an enemy approaching or sense danger.

Unlike some of the members of the crew, Zoro does not shrink from the idea of using deadly force against dangerous enemies and has been noted by several of his fellow Supernovas to be capable of exuding a tremendous amount of murderous intent.

Zoro is a master swordsman, being able to use one, two, and three swords in varying attack styles, going from melee-type all the way to artillery. Although he is most comfortable with his Santōryū (literally: three sword style), his skills with a single sword are very good, being able to hold off the Nyaban brothers, having bested several of the lower-ranked members of Arlong's crew (his two other swords were destroyed by Mihawk, leaving him only with the Wado Ichimonji), defeating Mr. 1, and most recently the zombie, Ryuuma. Lacking a third hand for a third sword, Zoro holds his third sword in his mouth. Some of his sword techniques use the air itself to hurt the enemy. Zoro often speaks with his sword held in his mouth, though it's unknown how he manages to do so. The creator of the series, Eiichiro Oda, has said that it is his heart that allows him to speak, though Oda is known for giving joke answers to fans' questions, as well as just making up answers on the spot to avoid leaving a fan's question unanswered.

Since no one else has been seen using anything similar, it can be assumed that Zoro invented not only Santōryū but most, if not all, of his sword techniques. He is even seen perfecting a new technique in his fight with Braham.

If he is fighting weaker enemies (or innocent bystanders that he has no desire injuring in the first place), like the Galley-La employees in Water 7, he uses only the blunt sides of his swords. Although, as Nami pointed out, due to his strength, even that could cause fatal wounds. A long standing problem with Zoro was his inability to cut steel. The anime incorrectly shows him instinctively cut steel during some of his encounters before learning how to control this ability during his battle with Daz Bones.

Zoro has shown a new ability called "Asura"which gives him the appearance of having six arms and three heads, like the deity of the same name. The exact nature of this attack is currently unclear, but Kaku suggested it was an illusion created by Zoro's spirit. He cut through Kaku's attack, and was able to deliver the finishing blow.

Though Brook became the crew's 2nd swordsman, the level of mastery and power between the two is significantly different, made obvious when both swordsmen have attempted to take on the same foe. While Brook had been unable to defeat Ryuuma (no matter how hard he fought) while Ryuuma only used a fraction of his power, Zoro was able to defeat him at full power with only two of his swords. At the Sabaody Archipelago, Brook struck a Pacifista with a high speed sword attack, yet failed to do much damage to it and had to be rescued from this result afterwards. However, when Zoro attacked the same Pacifista, the results were very different.

During his adventures, Zoro has acquired many swords. The three he currently uses are:
 * 1) Meitou; Wadō Ichimonji (formerly belonged to Kuina)
 * 2) Sandai Kitetsu (formerly belonged to Ippon-Matsu)
 * 3) Meitou; Shuusui (formerly belonged to Ryuuma)

For one reason or another, Zoro has one or more of his swords destroyed or incapacitated in some way:
 * 1) Katana x2 (destroyed by Juracule Mihawk)
 * 2) Johnny and Yosaku's swords (returned to them after battle)
 * 3) Meitou; Hana Arashi (Sogeking handcuffed to Yubashiri, stopped using when Sogeking was unlocked from Zoro)
 * 4) Meitou; Yubashiri (formerly belonged to Ippon-Matsu, destroyed on Enies Lobby by Shuu, now resting on Thriller Bark)
 * 5) Marine cutlass (destroyed by Shuu)

Nothing is known about Zoro other than as a boy, Zoro trained in a dojo in Shimotsuki village. Zoro states, in the Baratie that once he decided he would become an invincible Swordsman, he left his life behind.

Even as a child, Zoro was strong enough to defeat most adults, but could not defeat Kuina the Dojo master's daughter. After their 2000th fight (and Kuina's 2000th victory) Zoro challenged her in private for one more match - with real swords. She beat him, and he cried with frustration, telling Kuina his dream of being the world's greatest swordsman. Hearing this, Kuina confided in Zoro, telling him that she shared the same dream but knew she could never attain it - her father had told her that girls could never be true sword masters, and that her fighting potential would decrease as her body matured. Zoro, annoyed by her defeatist attitude in spite of repeatedly winning against him, told her that one day he would beat her because he was more skilled, not just because she was a girl. The two make a promise - that either of them must become the worlds best swordsman. The next day, Kuina died falling down the stairs of her dojo.

Zoro, remembering the promise, decided to fulfill the promise for both of them, and he asked the teacher for Kuina's sword, Wadō Ichimonji, and he started to develop a new fighting style - santōryū, a three-swords-style. Before her sudden death, Zoro fought with two swords, but after her death Zoro started using her sword as well, clenched in his mouth.

Somehow he eventually learned of Mihawk, who is currently the greatest swordsman in the world. Zoro eventually went to sea looking to find and challenge Mihawk to a duel, but got lost and could not return to his home. Since fighting is more or less the only thing Zoro is really good at, he would usually take on a bounty hunter job in order to pay for sword repairs and meals. From then on, he quickly made a reputation as a "Pirate Hunter". In a point of this time, he met and befriend with Johnny and Yosaku.

Because of his reputation, Zoro was offered a position and a number in Baroque Works because of his bounty hunting skills, but declined when he was not allowed to become the boss. Afterwards, he killed the person who offered, an earlier Mr. 7 of Baroque Works, for trying to kill him for refusing.

During his journey, Zoro arrived in Shell Town where Helmeppo, the spoiled son of the corrupted Marine captain Axe-Hand Morgan, released his pet wolf in town. It tried to attack a girl named Rika, but Zoro saved her by killing it. Zoro was arrested and Helmeppo made a deal with him: if Zoro could survive a month without food, he would be pardoned.

A few days before Zoro was supposed to be freed, Coby and Luffy arrived in town with the intentions of Coby joining the Marines and Luffy inviting Zoro to be his first crewmember. They arrived where Zoro was tied up, then Rika arrived to give Zoro some riceballs, but she was literally thrown out by Helmeppo. After they left, Luffy asked Zoro to join him but he flatly refused to become a pirate. He asked Luffy to feed him the dirtied riceballs and thank Rika for him, revealing his kindness. Later in town, Rika explained to Luffy and Coby the reason of Zoro be in such situation. With this in mind, Luffy decided to free Zoro from Captain Morgan and Helmeppo. Then Helmeppo commented that he would execute Zoro the next day. Angered that Helmeppo broke his promise, Luffy punched him and Helmeppo went to his father.

With the promise of giving Zoro his swords back if he'd join Luffy's crew, Luffy went to the Marine Base. Luffy caught Morgan's wrath and forced Helmeppo to show where Zoro's swords were. Meanwhile, Coby explained the situation to Zoro while trying to untie him. Luffy came back just in time to save them from a firing squad. Refusing to die, Zoro accepted Luffy's invitation and revealed his unique fighting style. He also revealed his dream of becoming the best swordsman in the world, which Luffy supports, believing that the Pirate King should have the best in his crew. Luffy fought with Morgan. However, when Helmeppo threatened to kill Coby, Luffy knocked him out while Zoro defeated the captain.

The Marines, seeing their tyrant leader finally defeated, rejoiced and allowed Luffy and Zoro to go free. However, since they were pirates, the Marines asked them to leave the island but promised not to report them to headquarters. As they were leaving, Commander Ripper asked about Coby's past. To help Coby hide it, Luffy provoked him into starting a brief fight between them. Zoro stopped the fight before it could get too serious, but it was enough for Coby to muster up the courage to ask Ripper if he could join the Marines, for which Ripper granted permission. Upon leaving, Luffy and Zoro were saluted by Coby and the Marines for their efforts. Luffy and Zoro then sailed onto their next destination.

After leaving the Marine Base, Zoro and Luffy realize that they don't know how to navigate, and begin searching for a navigator. Luffy manages to get his head stuck in the beak of a giant bird, leaving Zoro to paddle after him. Zoro comes across three pirates adrift at sea, and tells them to get on quickly because he wasn't stopping. The three are pirates working for Buggy The Clown and planned to rob/kill Zoro. Once they discover Zoro's identity, then begin rowing for him, though the commotion caused Zoro to lose track of Luffy's location.

In Orange Town, Luffy managed to get tricked by Nami, tied up, and put into a cage with a cannon aimed at him. Zoro shows up just in time to save Luffy and Nami from Buggy's crew. Zoro appears to slice Buggy into several pieces. However, Buggy is immune to blades due to his Devil Fruit powers. Buggy then stabs Zoro from behind, heavily injuring him. Despite this, Zoro manages to flip the cannon aimed at Luffy to point it at Buggy and his crew. Once the cannon is fired at them, Zoro picks up the iron cage Luffy was stuck in and drags him for a few blocks. After being taken in by Boodle, the mayor of the town, Zoro is taken care of and sleeps at his house until it is demolished by Buggy. Zoro rises from the debris, and is soon pitted against Cabaji, Buggy's second mate. Zoro defeats him, despite Cabaji hitting his wound several times. Zoro falls back asleep while Luffy battle against Buggy.

Nami agrees to temporarily team up with Zoro and Luffy, and the three sail off in the two small boats they obtained.

The first part of this arc sees the group land on a mysterious island inhabited by strange creatures. After passing the "Test" of the forest, the Straw Hat Pirates (now comprising Luffy, Zoro, and Nami) meet Gaimon, a pirate stuck inside a treasure chest that was marooned by his crew. The four become friends and Luffy agrees to help Gaimon get down the treasure he has been guarding on top of the rock. When Luffy refuses to throw down the treasure chests, Gaimon realizes that the chests on the rock are the same as the island’s other treasure chests which are empty. Seeing Gaimon’s disappointment, Luffy offers to take him off the island. Gaimon decides to remain on the island and protect the island’s rare animals which he has befriended. With that, The Straw Hats bid Gaimon goodbye and continue on.

After Buggy's incident on Orange Town, the crew then came upon Gecko Island. Upon landing, they met Usopp, the local troublemaker of Syrup Village and leader of the Usopp's Pirates. After some misunderstanding about coming to the island, they discover that Usopp's wealthy friend Kaya is bedridden, but is well-provided for by her two butlers Merry and Kurahadol. Luffy believes Kaya would be able to give them a boat, so they move forward to visit her. The group is sent flying into the backyard (by Luffy) only to intrude on an argument between Usopp and Kurahadol, who insults Usopp's father, and forces the group away form the house. While Usopp and Luffy bond, Nami and Zoro and the boys(Usopp's Pirates) come across the moon-walking hypnotist Jango.

After Usopp runs past them hysterically screaming that Kurahadol is a pirate, they go in search for Luffy. Luffy confirms that Kurahadol is actually Captain Kuro, who plans on killing Kaya and getting all her money. Usopp returns but tells the boys that it was just a lie, as they leave disappointed at Usopp lying to hurt people not entertain.

The Straw Hats gain a great deal of respect for Usopp for tricking the boys to protect their well being, and his planning to take on an entire pirate crew and agree to help him. Usopp planned to have an oil slip to stop the pirates, to which he could snipe them with ease. However the four are on the wrong side of the island. Nami falls into the oil slick but manages to switch spots with Zoro and runs off to fight. Luffy became lost on his dash, caused for Usopp and Nami to initially fight the pirates alone.

Just before the two are killed, Zoro and Luffy arrive and fight Kuro's crew. Jango hypnotizes the crew to increase their strength but accidentally hypnotizes Luffy, and Jango is forced to hypnotize Luffy to sleep again but accidentally causes the crew to be knocked out by the ship's stempost which Luffy was holding onto when he fell asleep. Meanwhile Jango summons the ship's guards the Meowban brothers, Buchi and Sham who fight against Zoro. Disarmed of all but one sword, Zoro must fight an uphill battle against the team-work of Buichi and Sham which is difficult without all three swords and Zoro prevents Usopp from helping him by taking a hit from his Lead Star to keep him from getting dragged into the fight. Kuro then appears disgusted by how Black Cat pirates are getting beaten by children and gives the Meowban brothers five minutes before he kills everyone.

Zoro still fighting at disvantage was helped by Nami who is able to recover Zoro's swords and kick back to him, allowing him to defeat the Meowban brothers, but Buchi survives and is hypnotized by Jango which injures Zoro faster. Nami goes to wake Luffy up, and Jango tries to stop her with his Chakram, but at the last second Nami steps on Luffy's face that gets him up in time to stop the Chakram with his rubbery body.

The battle of Luffy against Kuro, Zoro against Buchi and a latter combination of Zoro and Usopp against Jango comes to an end while Nami remains off screen robbing the Black Cat Pirates of all their treasure.

Usopp decides that news of a real pirate attack might be too upsetting for the villagers and would affect their peace of mind since pirates don't normally come to an out of the way village. So he orders everyone to keep it a secret, which Kaya and his crew agree with. Kaya, is grateful to the Straw Hat Pirates, and gives them her ship, the Going Merry (or the Merry Go in the English dub). Usopp is grateful to them as well, and now has the confidence to disband his pirate crew and strike out on his own to be a real pirate. Usopp says goodbye to the straw hat crew, who become confused and tell him to stop and get on their boat with them and that he is part of their crew.

The crew meets Johnny and Yosaku, Zoro's former bounty hunter companions, and they set sail for the Baratie restaurant in search of a cook. Luffy begins his job as a waiter to pay for the damage he did to the Baratie for Zeff, and tries to convince Sanji to join his crew. Gin returns to the Baratie with his also-starving captain, Don Krieg, to whom Sanji once more gives food, but Don Krieg betrays the cook once he regains his energy and attack the Baratie, despite the cooks' best effort to stop him. It is revealed that Chef Zeff was a great pirate known as Red Leg Zeff who traveled Grand Line for a whole year.

Gin explains the catastrophe the fleet met in Grand Line when they encountered Hawk-Eyes Mihawk, and Don Krieg attempts to take control of the Baratie. Mihawk has returned to finish the job with Don Krieg's Pirate Armada, but Zoro challenges him to a duel in order to achieve his dream. Unfortunately, he met a most devastating defeat at the hand of the swordsman. Mihawk leaves after defeating Zoro, so Don Krieg continues his invasion on the Baratie and has Pearl, one of his stronger crewmates, attack, and Sanji reveals his fighting skills. Johnny and Yosaku leave with Usopp and the wounded Zoro to go after Nami.

Usopp, Zoro, and Johnny arrive at the island but, seeing that three Fishman have spotted them, Usopp and Johnny abandon ship leaving Zoro (who was tied up by the two to, ironically, prevent him from fighting the Fishmen) to be captured by them.

Zoro is brought to Arlong Park where he finds out Nami's allegiance to Arlong. After some banter, Arlong proudly states that Nami is the type of person who would betray even her own family for the sake of riches, which visibly disturbs her. To test Arlong's statement, Zoro throws himself into the water. Nami saves Zoro but beats him to reassure that she is still part of Arlong's crew. While Arlong is away at Nami's village, Zoro breaks free from the dungeon (with some help from Nami, who cut his ropes) and defeats all the Fishmen there. He meets the octopus Fishman, Hatchan, who is outside the park and is oblivious to what happened in it. Thinking Zoro is a guest, Hatchan tows him to Cocoyashi Village. But when he arrives, Arlong had already gone back to the park after capturing Usopp.

Running back to Arlong park, Luffy, Yosaku and the newly recruited Sanji fall from the sky only to meet up with Zoro. Johnny finds them as well and tells them what he saw happened to Usopp. Nami soon meets up them and reminds Luffy that she just partnered up with him for the treasure. She then tells them to take their ship back and get off the island. But Luffy refuses, causing Nami to angrily walk away. Johnny and Yosaku also split off, not wanting to be killed by the Fishmen. Zoro says he never expected Nami to murder someone, that she was only a small time criminal. Sanji becomes enraged at the comment and the two starts to fight, only to have Usopp's face take the impact of both. Usopp wakes up and tells tells them of what really happened. Nami's adoptive older sister, Nojiko, finds them and agrees to tell them the reason behind Nami's motives. Though Luffy leaves to take a walk and Zoro falls alseep, Sanji and Usopp (as well as an eavesdropping Johnny and Yosaku) listen to the story of how Arlong took over the island and killed Nami and Nojiko's adoptive mother, Bellemere; and how Nami is working for Arlong as a cartographer and stealing from other pirates to buy back their village

Once Nami breaks down after Arlong has his accomplice, the corrupted Marine Captain Nezumi, take all the money she has been saving for her village, she asks Luffy for help. Zoro, Sanji and Usopp joins him on the march to Arlong Park where Johnny and Yosaku were stopping Cocoyashi’s villagers entrance and waiting the Straw Hats. After entering, they manage to beat almost all fishmen there. But Luffy, after sticking his feet into the ground to beat the Arlong's sea-cow Momoo, is thrown into the water by Arlong. Zoro, Sanji and Usopp take on Hatchan, Kuroobi and Chew respectively. Despite his wound and fever, Zoro manages to win against Hatchan's six-sword style (borrowing Johnny’s and Yosaku’s swords), breaking his swords and defeating him. Sanji defeats Kuroobi and Usopp defeats Chew outside Arlong Park.

After Sanji assures Zoro that Luffy is alive, he and Sanji then fight against Arlong. But they both get defeated and agree that only Luffy could win. While Zoro keeps Arlong distract, and with minor interference by Hatchan, Sanji dives back into the water and frees Luffy's body. But on land Arlong rips off the bandages on Zoro’s chest, injuring him even more and shocking everybody. Luffy rises from the water and trades places with Zoro by tossing him into the air. He falls into the sea and falls asleep after pulling himself out of it. When Luffy destroys Arlong Park and defeats Arlong, Zoro wakes up in time to beat Nezumi, who came to take the credit of defeating Arlong. Nami makes Nezumi return all the money and help fix up the island. Humiliated, Nezumi leaves and reports the incident to the Marine's Main Base, ensuring that Luffy recieves a high bounty.

Back in Cocoyashi Village, Dr. Nako tends to the wounds of Zoro, Luffy, Yosaku, and Johnny. Then, to celebrate their freedom, the entire island throws a big party. When the party is over, Nami rejoins the crew and the Straw Hats sail to their next adventure.

Having defeated Buggy, Kreig, and Arlong, the Marines issue Luffy his first bounty. Luffy, Usopp, and Sanji start to discuss Luffy's wanted poster. Meanwhile, Zoro points out an island he has spotted. Nami explains about the island' major city, Loguetown, the city of the beginning and the end, where the Pirate King Gold Roger was born. It was also the place he was executed.

Arriving at Loguetown, Zoro stated that he wants to buy something, so he asks Nami for some money. While walking down the street, Zoro witnesses Tashigi, a marine swordswoman exactly like Kuina, beating some pirates. Upon entering the Weapons Shop, Zoro looks for two swords. The owner of the shop, Ippon-Matsu, tries to trick Zoro into selling his beloved sword for far less than its value, but Tashigi rushes into the shop and accidentaly ruins the owners business. Tashigi points out a cursed sword named Sandai Kitetsu to Zoro. Ippon-Matsu tells to them about Kitetsu' curseline, which intrests Zoro. The latter decides to buy the sword and test his luck against the sword's curse (he throws the sword up, then holds out his arm), but the sword circles around Zoro's arm. After witnessing Zoro's calibre, the owner gives Yubashiri to Zoro for free, saying that he passes his dream to him.

After leaving the shop, Zoro reunites with the crew, except Luffy, who is in trouble. So, Zoro and Sanji rush to the execution place and start to fight Buggy' crew, hoping save Luffy, but the latter is save by lightning that strikes the place (since he is made of rubber, it doesn't damage him). Zoro, Luffy, and Sanji rush from the execution place to reach Going Merry, but Tashigi and Smoker intercept them. Tashigi engages Zoro in battle, and Smoker battles Luffy and Sanji. Zoro defeats Tashigi, and Dragon saves Luffy from Smoker. Finally, they reach Going Merry and leave Loguetown. Following this, the Straw Hats make promises about their dreams and sail to the Grand Line.

Heading to the Grand Line, Nami search for more information about it. Then, the Straw Hats make a reunion where Nami explains about the only way to reach Grand Line, the Reverse Mountain.

The Straws Hats arrive at Reverse Mountain through the storm, though they are nearly blown off course and into the Calm Belt but eventually reach the entrance of Reverse Mountain and manage to climb its uphill rapids despite some tricky close calls. As they come down they hear a noise and notice something is blocking their path. They identify the blockage as a huge whale which is threatening to crush the Going Merry. Luffy manages to keep the ship from crashing into it, but seeing the bow broken off enrages Luffy and he attacks the whale. The whale swallows the Going Merry and the crew, except for Luffy who manages to escape onto the whale's back. Inside, the Straw Hats suddenly find themselves in what looks like an outside setting with a house in the middle of the water where they meet an old man named Crocus. Sanji tries to get information from Crocus, who look long periods of time to reply, causing Sanji and Zoro great comical frustration. Eventually Luffy reunites with the Straw Hats and it is revealed that the strange setting is in fact the whale's stomach. Crocus reveals that the whale's name is Laboon, and he cries trying to run into the mountain because of a promise made 50 years ago and that two mystery people named Mr.9 and Miss Wednesday are there just to kill the whale to feed the people in their town, but they are knock out by Luffy.

Once they exit Laboon, the Straw Hats throw Mr.9 and Miss Wednesday on the sea. Luffy makes a promise to the whale hoping solve his past problem. The crew is making the preparation for their journey when Nami realizes that the compass doesn't work there, Crocus explains that they need a Log Pose to travel through the Grand Line and gives to them one, also Mr.9 and Miss Wednesday ask the Straw Hats to take them to their town. Since everything is ready they sail onto the first Grand Line island.

Zoro and the crew arrive at Whiskey Peak, a town of pirate-lovers who hold them a feast. Zoro battles a hundred members of Baroque Works, and discovers there is more to them than meets the eye. Luffy, not realizing the town is full of bounty hunters, engages in a battle with Zoro after Zoro attacks the townsfolk. Luffy's crew manages to become targets of Crocodile, one of the Shichibukai, and decide to help Princess Vivi. They also meet Miss All-Sunday, the number two in Baroque Works, and assistant to Crocodile. While she attempts to offer them an Eternal Compass to an island near Arabasta, Luffy breaks it instead of allowing an enemy to decide their destination.

Zoro and crew land on Little Garden, a prehistoric island inhabited by dinosaurs and giants. Zoro ordered by Sanji to gather some food has challenge him for a competition who will be the one to bring the largest meat. The Straw Hats little suspect that Officer Agents of Baroque Works are on their tail. Having subdued the giants, Baroque Works makes their move. Mr. 3 introduces Zoro, Nami, Vivi, and Brogy to the slow torture of becoming living statues of wax. Agreeing with Broggy that the only way to die was to go out honorably and tries to cut off his feet but fails, and decides instead to let Luffy, Ussop and Carue save them. Luffy attempts to rescue his friends, however, only accelerates the deadly waxing process forcing Zoro to strike an honorable pose should he die. To make matters worse, Miss Goldenweek interferes with and reveals her own terrifying ability. Usopp frees Luffy from Miss Goldenweek's control by burning Luffy's shirt. With Carue's help, Usopp and Luffy rescue the others, who take on Mr. 5 and Miss Valentine. Luffy and Carue pursue Mr. 3 and Miss Goldenweek into the forest. After being freed by Luffy from the wax, the crew managed to defeat the agents. The crew leaves Little Garden being propelled through the Island Eater and sets sail for Arabasta.

While out at sea Zoro begins his daily training again and while looking for a doctor for Nami, the crew meets the pirate Wapol, who attacks them, but only makes Luffy send him flying. They arrive at last to an island only to find out they're not welcome. The Straw Hat crew manages to gain the trust of the people that attacked them, and are taken to the village, except for Zoro and Carue, who guard the ship, with Zoro deciding to train in the icy cold waters now that his injuries from Little Garden had healed. A shirtless Zoro later aids Vivi and Usopp in dealing with the king's army in order to save Dalton, and obtain one of their warm coats in the process to warm himself back up. The villagers along with Zoro, Vivi and Usopp start their ascent to the castle through a ropeway. After finally been convinced to join the team, Chopper announces his intentions to Dr. Kureha, who doesn't take it too well; but after escaping from the castle, she has decided to give the whole Straw Hat crew a farewell gift. On the way out of the Island the crew discover Carue frozen in the water and rescue him, where Chopper translates that Carue jumped in the water to save Zoro when he saw him disappear, causing an angry Nami to hit Zoro on the head because he was at fault for this mishap.

They entered the crew starving for food and saw a seacat. They try to capture it but Vivi stop them because its rare. They meet Mr. 2 Bon Kurei in the ship who shows off his devil fruit power and Vivi sees a shocking sight. Upon learning his abilities, they plan to make a x mark on their right arm to know their true identity. The crew landed in Nanohana, they encounter Smoker and Tashigi. A powerful pirate named Portgas D. Ace appears, and is revealed to be Luffy's older brother. Ace fights Smoker while the Straw Hats run for their ship. Luffy reunites with his brother, and together take down agents of Baroque Works. Ace depart from the crew and he gave Luffy the paper of life. The crew finds out that the Rebel Army has moved out of Yuba and headed to Katorea, and the rebel leader Kohza is determined to attack. The crew travels to the city of Rainbase to take down Crocodile and Baroque Works, but run afoul of Smoker and Tashigi.

Zoro, Luffy, Nami,and Usopp, along with Smoker, are trapped by Crocodile. Chopper distracts Crocodile while Sanji frees the rest of the crew, but find themselves trapped yet again. After escaping from Rain Dinners, Zoro and the crew together with Vivi cross the desert to Alubarna, where the final battle will take place. Crocodile, however, manages to catch Luffy, beginning the first round of their battle. The crew excluded Luffy proceeded to the Alubarna. As they reach the destination, they split up to distract the Baroque Works agents to engage their battle separately. While Miss Doublefinger's fight with Nami was challenging, Zoro is having an even more difficult time fighting Mr. 1: A man who can change his entire body into steel - something that Zoro can't cut. As Zoro nears death, he must discover the secret to "the breath of all things". After their battle, the other Straw Hats hurry to locate the bomb before it goes off. Vivi finds the bomb, and calls the Straw Hats together. Vivi finds the bomb inside of the clock tower, but the Mr. 7 pair of Baroque Works are there to protect it. Vivi defeats them, but she realizes the bomb cannot be stopped so easily. It has a timer, and right before it blows up, Pell shows up and takes it into the atmosphere, where he sacrifices himself to save Arabasta.

Now that the battle has ended, the outcome is tallied. Igaram appears with proof of Cobra's innocence, as well as Kohza telling everything. When Luffy awakens from his battle form Crocodile, a magnificent banquet is thrown for the pirates, then, the Straw Hats are invited to enjoy the hot spring steam room inside the palace. It's the day for Vivi's speech and her decision whether or not to continue to be with the Straw Hats. Meanwhile, Bon Clay and his crew attempt to protect the Straw Hats from Hina. When Vivi arrives at their location, the entire Straw Hat show off their x mark symbolize their friendship with Vivi. The Marines fail again to catch the Straw Hats. After escaping from the Marines, Nico Robin (Ms. All Sunday) appears from inside of the Straw Hats ship. She manages to persuade the crew to let her join.

Nami's Log Pose begins to point to the sky, after that, a big ship falls from sky and the crew finds a map in of an island named 'Skypiea' on a 200-year-old ship. They compete with the monkey-like Masira's salvage crew while they search for more clues on how to get there. The Straw Hats decide to go to Jaya island to look for information on Skypeia. Jaya's main town is full of famous pirates that are constantly brawling with each other. Luffy and Zoro have a run-in with a pirate known as 'Bellamy the Hyena', who ridicules their dreams and beats them up. Luffy, Zoro and Nami meet the man who is later revealed to be Blackbeard. They leave Mock Town, and get into a fight with Masira's brother Shojo, another salvage monkey.

The Straw Hats meet with Montblanc Cricket on another part of Jaya; Cricket is a descendant of Montblanc Norland, an infamous "liar" who told of a gold city on Jaya, and Cricket was outcast for looking for artifacts of the gold city. He may be the only person who knows how to get to Skypiea. Cricket explains how the Straw Hats can ride a dangerous vertical current called the Knock-Up Stream to get to Skypeia. However, they first have to catch a South Bird to point them toward the point where the stream will erupt from the ocean. While the Straw Hats are looking for a South Bird, Bellamy and his crew attack Cricket's house, and steal the gold artifacts he'd collected over the years from his salvage work. When the Straw Hats return and see what happened, Luffy decides to take a side trip back to Mock Town. The Going Merry is refitted by Masira and Shojo to be more flight capable, and the Straw Hats catch a ride on the Knock-Up Stream for Skypeia. The Straw Hats arrive in an ocean above the clouds.

This section needs to be cleaned up and more detailed. They start from entering the Gate of Heaven. First they have been recommended by an old woman to pay their extol, but even they haven't pay the old woman let their pass. As they carried by a sky shrimp, they landed on a place that's surrounded by clouds. They meet Conis, a Skypiean. As their conversation continues about the waver, the White Berets interrupt them and labeling them as a criminal of illegal entrants. As Zoro, Nami, Chopper, Robin aboard the ship, the shrimp suddenly carried them, Zoro tried to kill it but there's something behind. The shrimp leave them in the Sacrificial Altar. Zoro, Nami and Robin explored the land and they discovered it as a part of the Jaya. As they go back to the ship, they saw Luffy, Usopp, and Sanji. As they sleeped, Usopp wakes him up about a ghost but he ignored it. As the sun rises they prepared for battle to search for the gold. Zoro, Luffy, Chopper, and Robin were exploring the island when suddenly a giant snake named Norla attacked them. As a result, the four run on a different locations effecting them to be alone. Zoro encounters Braham and get difficult in fighting because of Braham's flash dials used on his pistols.

After he defeated Braham, he ate his lunch when a giant Southbird interrupts and hawked him up. Zoro, together with the Southbird are being chased by Norla. The Southbird let Zoro fall to run for its life. Zoro landed between the fight of Ohm, Wiper, and Gan Fall. As he is fighting Ohm, he saw a knocked out Chopper, later he manage to defeat Ohm and it's dog. As Enel destroyed the cloud, they fall to ruins of Shandora, together with Robin and Chopper,Nami, Gan Fall, Luffy, Aisa inside Norla's stomach. Enel declared that the survivor of his game will be his next disciple, but Zoro, Robin, Wiper, and Gan Fall declined. Enel attacked Robin and get unconscious then Zoro avenge her but got defeated too. As he regained his conscious, he witnesses that Enel has already destroyed Angel Island. He cuts the giant Jack but got hit by Enel and failed to make it fall down. As he regained consciousness, he celebrates with the crew and all Skypieans.

Next day, they collected a big number of gold, a group of Shandians and Skypieans carried the a one post of gold, mistaking that it is a cannon. They start to run stating that they will attacked them; on the other side they want to give it to the crew. With the help of Pagaya and Conis, the crew manage to return to the Blue Sea.

After returning from Skypiea, the Straw Hats come across a mysterious pirate ship with no captain and navigator after trying to escape a giant wave. Soon they arrive at an island with some strange long animals, the Longring Longland Island. As Luffy, Usopp, Chopper go onboard, Zoro, Sanji, Nami, and Robin are challenged by the Foxy Pirates to a Davy Back Fight with Luffy. Luffy accepts it with a gun shot. When Foxy decides to take Chopper after the first round, the "Donut Race", Chopper cries, saying that he only went out to sea because he knew that his nakama will be the Straw Hats. Zoro lectures Chopper, telling him that he must be a man and that he is responsible for becoming a pirate. In the second game, called "Groggy Ring", he and Sanji are partnered. They are fighting over who who will be the 'ball man' until Sanji takes the position (at Nami's request). The referee tells them that weapons are prohibited in the game, so Zoro was forced to use No Sword Style. They defeated the Groggy Monsters and won, allowing the Straw Hat Pirates to reclaim Chopper. The last game, "Combat", is a fight between the two captains. Luffy defeats Foxy and chooses to destroy the Foxy pirate flag rather than steal a crew member. Luffy makes them a new flag, which ends up being hideous because of his poor artistic ability.

After returning to Tonjit's hut, they meet the Admiral named Aokiji (in the anime, they meet him on a different island). When Robin sees him, she is shocked and trembles. Aokiji tells them that he is only there to confirm that Robin is still alive. Aokiji states that he will eliminate Luffy. Aokiji uses Ice Saber to slice up Robin, but Zoro stops it. Sanji immediately kicks the sword and Luffy runs toward Aokiji to release a Gomu Gomu no Bazooka, but they get frozen in one attack. Zoro's right shoulder gets frozen. Robin attacked Aokiji then break. Aokiji hugged Robin and got fully frozen. Usopp and Chopper immediately carry Robin to the ship for a treatment. Zoro and Sanji follow them later. When Usopp questioned them where is Luffy, Sanji states that Luffy challenged Aokiji a mano e mano or one on one duel. When he comes back with Sanji, they seen Luffy got frozen too. They carry him to the ship for a treatment like Robin. After being treated, Zoro thinks that Luffy got stronger to fight a stronger enemy.

As the Straw Hats continue their journey, they encounter a sea train on their way. They stop at a train station and ask an old woman named Kokoro where they can repair the ship and recruit a shipwright. Kokoro gives them a picture of a person named Iceburg and told that is the person for whom they are searching. They set sail and open the picture only to find it was only a drawing. When they arrived at Water 7, Zoro pulled out the sail and accidentally breaks it. Soon Luffy, Nami, Usopp go onboard to hire a shipwright immediately. Then, Robin and Chopper go shopping followed by later by Sanji. Zoro remained sleeping and guarded the ship. When a man named Kaku, a shipwright from the Galley-La Company came in to check the ship, he mistook him for Usopp. Upon completing the inspection, Kaku states that the ship can't be repaired anymore. Zoro disagrees. Soon the carpenter went home. Later, the ship has been surrounded by a mysterious strangers called the Franky Family. They attacked but were easily defeated by him. He later joins Chopper, Sanji, Luffy to look for Usopp and their money. They found Usopp unconscious outside of the Franky House. They attack the Franky Family and destroy their base, more so for beating up Usopp than for stealing their money.

While Usopp is under medical treatment from Chopper, Luffy decided to get a new ship. When Usopp wakes up, Luffy tells him this and Usopp angrily disagrees. They start a quarrel whether they will leave the ship or not. Usopp goes outside saying that he quits being a Straw Hat Pirate, then he challenges Luffy to a duel, the winner claims the ship. Later, Zoro is seen fighting with Sanji over who is the responsible for it. They also wondering where Robin had gone. After the duel, Zoro tells Luffy that, as captain, he must never hesitate. Otherwise the crew can't rely on him. He then states that they can never come back to the Going Merry again. When they rent a hotel room, he just sits on the rooftop. Later lost of running away from civilians because the entire Straw Hat are suspects to attempted murder of Iceburg.

When Zoro saw Luffy, Chopper, and Nami, they plan how to enter to the Galley-La to talk to Iceburg. As Luffy disappeared, they've been spotted by the Galley-La guards and start running. When Zoro became annoyed of the carpenters, he decided to use the back of his swords to defeat them. As they enter the building, they see Luffy with Paulie, there, they discover the true identity of Blueno, Kalifa, Kaku, and Lucci as CP9. They see Robin with them too. Zoro attacked Kaku saying that he is not a true shipwright but Kaku replied that he did his job correctly when examinating Going Merry. Afterwards, Zoro was quickly sent by Lucci in Leopard form flying into a chimney.

While he was stuck on a chimney he was helped by Chopper, who gave him Kitetsu and he destroyed the chimney. When he was finally freed, Zoro and Chopper ran as quickly as possible to get away from the Aqua Laguna. Zoro and Chopper, along with Nami and Luffy, were helped by Paulie from drowning. As they plan to sail in a storm to save Robin, Paulie disagreed to their plan as he will fight them to stop them. Kokoro arrives there and introduce the Rocketman, another sea train.

Seeing how determined Luffy is to save Robin, Kokoro and Iceburg lends the Straw Hat crew the use of another sea train, Rocket Man. The [Franky Family] shows up, pleading with Luffy to let them join them because they'll do anything for their leader. The Rocket Man finally makes it out to sea. As the train connects with the tracks, Luffy has to rescue Chimney before she's thrown off by the wind. In the meantime,With Luffy and Chimney safe in the train, Paulie tells his fellow carpenters who the real culprits were. The Straw Hats, Franky Family, and Galley-La Company form an alliance. Luffy and Zoro perform a move that acts similar to a cannon and blasts a hole through the wall of the tidal wave ahead of them, opening up a channel for them to pass through. They miraculously pass through unscathed and the passengers rejoice.

In the Rocket Man, Luffy, Zoro, Nami, and Chopper get an outfit change; Nami shows off the weapon Usopp upgraded for her while he was still with them. Those on the Rocket Man encounter the discarded cars and Zoro slices them so they can pass. Zoro clashes with "Ship Cutter" T-Bone. The fight is short and Zoro joins the crew again in the Rocket Man. at the Rocket Man, Yokuzuna the frog jumps onto the front of the train, knocking them from the rails. After Kokoro speaks with him, he joins the group. Luffy and the others finally catch up to Sanji, Usopp, and the rest of the Franky Family as they near Enies Lobby. Paulie sits down with the group and talks about their plan. Luffy doesn't bother to follow the plan, and slingshots himself beyond the gates before the train stops.

As they arrive at the Enies Lobby, together with the Franky Family and Galley La, they plan their move going inside the Enies Lobby. But unfortunately, Luffy go earlier from the plan. They wait several minutes to open the 1st gate of Enies Lobby. Zoro has been commanded by Kokoro to make his move against the fence. But suddenly, Zoro commanded Yokuzuna to pull the fence and made it as a ramp. Together they landed on Oimo's back. They start entering the island to its main aim; saving Robin. He cut the last gate and then proceed. As they waiting for the bridge to be activated, the all lined up at the roof convincing Robin to accept their request of saving her. When they confirmed that the bridge will not be activated anymore, Kokoro voluntered herself to help them using the Rocketman. The Rocketman used the half activated bridge as a ramp and together they've been held by Luffy and started to jump.

When they landed on the Tower of Justice, Fukurou showed up and declares that a key is needed to uncuff Robin. They decide to fight individually and started to search an agent. Zoro faced Kaku and a battle of swordsmen has started. Since Zoro has already fought Kaku at Galley La, Zoro commented that he has became stronger since then. He uses a new skill to defeat Kaku and finally got his key. The key is number 5. After that he and Sanji carried the injured Sogeking in the tunnel and get drowned. They have been saved by Kokoro who is a mermaid. Later he fought some bunch of Marines to defend their escape ship. His Yubashiri has been rusted by Shuu. Their escape ship explodes. As they fight the Marines he heard the voice of Merry who is saying jump over the sea. Together they jump at the sea an sailed.

With the Going Merry, everyone has managed to escape Enies Lobby safely. However, after escaping, Iceburg arrives with the Galley-La company just in time to pick up the Straw Hat Pirates as the Merry suddenly breaks apart. Luffy then gives the Going Merry a viking funeral by burning it as the crew tearfully says goodbye (Zoro, though, maintained his dignity).

2 days later, back in Water 7, he is seen staring at the broken hilt of his sword wondering what he should do. Finally, he was then seen rushing to meet the others, to warn them of the marines arrival. However, as usual, Zoro ends up getting lost on the way there. When he arrived, he was attacked by Sergeant Helmeppo with dual kukri knives, but quickly defeated the young man.

He was seen trying to buy a sword but had no money and was thrown out. Later on, Zoro's new bounty is revealed; the bounty is set at 120,000,000 beri. He also helped launch Franky towards the "Thousand Sunny", the Straw Hat's new ship. He was later seen, when he and Sanji inform the rest of the crew that Garp's battleship was near the island. Zoro took a stand on letting Usopp back in, Zoro stating that Usopp shouldn't be allowed back with the crew if he returned still full of pride. His reasoning being that Luffy as captain must stand firm as it was Usopp that left them and lost the duel with Luffy over the fate of the Going Merry. As so, he smiles when Usopp apologizes for being stubborn and asks if he can re-join the crew.{|class="cquote" style="border-style: none; margin: auto; border-collapse: collapse; background-color: transparent;" -Part of Zoro's speech on Usopp rejoining.

 * valign="top" style="padding: 4px 10px;"|When Luffy and Usopp started arguing in the first place... I didn't care about whose emotions were stronger... or who was correct... but a duel between men was fought and the conclusion was set in stone.

After sailing for some time on the Thousand Sunny, Zoro and the rest of the crew came across a mysterious barrel floating on the ocean. Upon opening it, a flash shot up from it. After braving a storm that mysteriously came afterwards thanks to Nami and Franky, Zoro and the rest of the crew found themselves in the presence of a ghost ship.

This ship apparently belonged to a skeleton named Brook who, by chance, initially accepts Luffy's offer to join the crew. This apparent new addition to the crew made Zoro scold Nami and Sanji for not keeping Luffy from inviting the skeleton. Zoro then joined for dinner as the skeleton related his past to the others. Just as Brook was about to perform before Zoro and the rest of the crew, a ghost appeared and some clanking sounds were heard. These sounds were caused by the gates of the island that suddenly appeared, Thriller Bark, closing. These events prompted Brook to head to the island before Zoro and the rest of the Straw Hats' eyes.

After witnessing Franky's present to the Straw Hats that the cyborg decided to show them, Zoro and the rest of the Straw Hats decided to look for Nami, Usopp, and Chopper who had not returned. However before Zoro and the rest could go to the island, they were stopped by an invisible thing. The thing stole one of Zoro's swords and tried to stab Luffy with it. Luckily, Franky kicked it away before it found it's mark. The thing later left Zoro and the rest baffled.

After the Thousand Sunny was caught in what was apparently an oversized spider web, Zoro and the rest disembarked onto the island. There, they met the Cerberus which didn't intimidate Zoro. After Luffy tamed the beast, Zoro and the rest met two more of the island's creatures. Luffy caught the "Geezer Tree" while Franky caught the unicorn. Zoro, along with Sanji, then stopped Luffy before he could allow the "Geezer Tree" to join the group.Zoro and the rest then came across some ghosts who affected some of them with their strange abilities. Zoro seeing his companions in such a pitiful state merely shook the whole matter off only to be affected by one of the ghosts himself. After Zoro and the rest who also affected by the ghosts recovered, they pressed forward. Zoro and the rest later met with some Zombies and defeated them with a combo technique. The group then met with a old man who looked like a Zombie. The old man asked them to defeat Gecko Moria who had stolen his shadow.

While in Hogback's mansion, Zoro disappears not long after Sanji does. Later, a shadowed figure was shown attacking Robin, Luffy, and Franky with Zoro's Ittouryuu: 36-Pound-Cannon attack. However, the zombie's body was that of Jigorou, the zombie that received Zoro's shadow. It is later reveled that the zombie has inherited Zoro's Shadow and thus is able to use all his techniques. Zoro was found asleep on the Thousand Sunny with Sanji and Luffy and was woken up by Usopp.

After purifying some Zombies, Zoro, Franky and Sanji are about to cross a bridge leading to Hogback's laboratory when Oars smashes it. With the construction of a new bridge done by Franky, Sanji departs to save Nami. Later on Zoro and Franky finds the defeated Brook, and saves him in the last moment from "legendary samurai" zombie. Seeing the samurai's sword Zoro claims he intend to fight and take it. After a short but intense battle, he defeats the legendary samurai and gained the sword Shuusui, from an ashamed Ryuuma.

When Moria gained control of Oars, he ordered him to rampage Thriller Bark and defeat the Straw Hats. Zoro wanting to fight him only cut of his left tusk before being defeated by Oars' attack. Later on he alongside the other Straw Hats regain consciousness and started a series of combo attacks against Oars. Using a 108 Pound Cannon at Oars, Zoro notes how his Shuusui is heavy and he is still not adept using it. After Moria manipulates Oars' body to allow it to stretch the Straw Hats are taken down one by one. But before Zoro is taken down, Chopper formulates a theory that his right arm is his weak point. As his final movement, Zoro tried to damage the arm, but fails since zombies do not feel pain, and is taken out.

After being carried away from the fight between Nightmare Luffy and Oars, by the Thriller Bark Victim's Association, he regains consciousness, and helped Luffy use Giant Bazooka to shatter Oars' spine. As Moria uses Shadow Asgard he stands by, watching the fight between Moria and Luffy, and is almost burned away by the sun until, with the defeat of Moria, his shadow is finally returned. After launching an attack on the Thriller Bark Victim's Association Bartholemew Kuma targets Zoro.

Zoro tries to fight Kuma, but Kuma just pushes his attacks away with his Nikyu Nikyu no Mi, leaving Zoro at a disadvantage. Kuma then comes with an ultimatium: give up Luffy and the rest will be allowed to survive. Zoro and the crew refuse and so Kuma calmly detonates the island with an Ursus Shock, knocking out everybody. However, when Kuma was about to take Luffy, Zoro rises again and even launches a succesfull Shishi Sonson [Lions Song] on Kuma, revealing that he is cyborg. Kuma then states that he is a cyborg but not like "Cyborg" Franky and furthermore tells that he is an incomplete human weapon, created by the World Government, and Dr. Vegapunk, called Pacifista. Zoro then proceeds to ask for his head to be taken in exchange for Luffy's. Kuma agrees, but at that point Sanji wakes up and wants to give his head instead. Zoro calmly hits one of his wounds and knocks Sanji out. Kuma then proceeds to use his powers and draw out all of Luffy's pain and fatigue. Luffy had so much pain and fatigue that it formed a gigantic paw of energy. Kuma gives Zoro a small sample of it and Zoro can barely tolerate the pain. Zoro then says "Let me choose the location". Zoro then takes the paw of pain and goes to a nearby forest. He takes a few breaths before he places his hands inside of the giant paw. When the Straw Hat crew awakens along with the Rolling Pirates, Sanji goes out to look for Zoro and finds him in the forest covered from head to toe in blood. When Sanji asks what happened to him, Zoro replies "Nothing... nothing at all" in a trembling voice. None of the Straw Hats find out about Zoro's near-death sacrifice but Sanji, Robin and Brook.

He is seen sleeping in the Thriller Bark Mansion, with wounds Chopper says were life threatening, while his nakama (minus Chopper, who was taking care of him and Nami, who was watching over him) celebrate their victory. Two days later Zoro is awake and goes to the grave that Franky built for Brook to honor the Rumbar Pirates and asks Brook permission to lay his Yubashiri to rest near the grave and later jokes that Brook has bad luck since this crew is varied to which Brook jokes back with him.

Once he and the rest of the crew finally left Thriller Bark, they held a toast to Brook, their new nakama.

As the Straw Hats continue their journey, Zoro became embroiled in the battles against the Flying Fish Riders in protection of former enemy Hatchan against the slave trader Duval. Assisting Hatchan in his escape, he comes to an understanding with his former enemy while defeating those in their way. After the incident, the Straw Hats arrived at the Sabaody Archipelago, where Zoro decided to go off on his own, presumably to get some liquor, as he was later seen chugging on a bottle of one. Though he claimed he knew where the Sunny was docked, a misread sign made the swordsman run off into the unknown, getting himself lost again. Eventually, he enters a bad area where a Tenryuubito is messing around with his slaves and the local population. Although other members of the The Eleven Supernovas were watching, Zoro attempted to challenge one for his mistreatment. But before he could get too far, Jewelry Bonney knocked him out of the gunfire, forcing him to play along to escape the Noble's wrath. After a brief argument with Bonney, Zoro proceeds to carry the civilian injured earlier by the Noble to the nearest hospital, ignoring Bonney's protests. Several of the Supernovas watching the encounter comment that Zoro is a 'beast' and radiates an 'insane killing intent'. They contemplate how powerful his captain (Luffy) must be to keep such a powerful and seemingly uncontrollable man, with such a high bounty in check.

He apparently jumps onto Luffy's flying fish (after being told by the latter to) in an attempt to find his way back to the ship, but is crashed into the Auctioning House along with them. After Hatchan is shot, Zoro witnesses Luffy punch Saint Charloss in the face, the same Noble he himself almost attacked. Zoro remarked that Luffy should've given him the chance to slice the noble himself. He also witnessed the mechanic they were looking for, Silvers Rayleigh who uses an ability known as "Haki" to knock out most of the crowds, as well as Saint Shalulia. Zoro assisted Luffy and battle his way out the massive horde of Marines, before escaping along with Rayleigh with the help of Duval's Rosy Life Riders.

They return to Shakky's Rip Off Bar to rest. There, Rayleigh reveals he was Gold Roger's First Mate, and reveals the truth about how what led to his execution. Indeed Roger was never captured, rather he gave himself up. Four years before his death, Roger contracted an incurable illness and spent most of the years going on his final adventure to the Grand Line, eventually reaching the end, and conquering it. Roger then became known as the Pirate King, but that didn't matter to him as he was still about to die. A year before his death, he secretly disbanded the Jolly Roger Pirates and the members disappeared. Roger mentioned to Rayleigh that he isn't going to die. in Roger's final year, he gave himself up to the Marines, and sentence to public execution. The Marines publicly claimed that they captured Roger as a show of power, and used his public execution to set an example to all pirates, but his last words before his death started "The Great Pirate Age". While Rayleigh himself didn't witness Roger's execution, his subordinates, Shanks and Buggy were present. The mention of the latter mildly irritates Zoro.

Rayleigh congratulates the Straw Hats on making it to the first half of the Grand Line but tells them he's going to need three days to coat the Thousand Sunny. In addition due to the arrival of an Admiral, he will move the ship as not to be noticed, so he gives the Straw Hats pieces of a Biblicard to meet up once its done. Because of the Admiral threat, Zoro mentions they too should split up, to avoid getting caught and meet up at Rayleigh's location. Sanji notes that this is an ironic comment going from him. As they say their farewells to Shakuyaku, Keimi, Pappag and Hatchan, the Straw Hats depart but are confronted by the Shichibukai Bartholomew Kuma. As he attacks, the Straw Hats retaliate, now at full strength as opposed to worn out from their prior encounter at Thriller Bark. Zoro notes that there is something different about his "atmosphere" from before. The Straw Hats continue to fight "Kuma" and Luffy, Sanji and Zoro finally deliver a successful counter-attack in the form of the Gomu Gomu no Diable Jet Mouton 600 Pound Cannon combo, knocking "Kuma" back. Zoro notes that it may not be the real Kuma as he hasn't reflected their attacks or teleported with his Nikyu Nikyu no Mi abilities. This poses a problem because there is one or more copies of Kuma with similar levels of strength. Zoro suddenly collapses from the phantom pain of when he had all of Luffy's pain and fatigue was transfered to him but managed to get up and hit Kuma with a new Asura technique which badly damages the clone, before Luffy finishes it off.

As the Straw Hats catch their breath, they contemplate how powerful their opponent was, and how he came so early as they planned to hide for the next three days, and were worried as to how they are going to deal with more opponents like that. Just then, a broadaxe-wielding warrior named Sentōmaru appeared with yet another Pacifrista and ordered it to capture the Straw Hats. As the Straw Hats separated to avoid capture, Zoro, Brook and Usopp were suddenly confronted by Kizaru: one of the 3 Admirals and he proceeded to attack Zoro with a blast from his kicks. With Usopp and Brook unable to do anything to Kizaru due to the power of the Pika Pika no Mi, the Admiral attempted to finish Zoro off, but had his kick deflected by Silvers Rayleigh appearing to save him. Usopp and Brook again try to escape with Zoro, but as the PX-1 Pacifista starts coming after them Zoro tells them to put him down, and he will let them get away. But Usopp refuses saying Zoro is more useless than him right now. Even with Sanji's help they are all beaten down by the Pacifista. Before they can get up to run again, or it can attack once more, the real Bartholomew Kuma shows up, and orders the Pacifista to stop. Zoro instantly recognizes this as the real one, and they briefly talk, before Kuma asks Zoro "Where would you like to go?", while removing his glove. He then swiftly touches Zoro with his hand, making him vanish.

He is shown having landed in the exact same spot Perona was sent to, the ruins of Shikkearu Kingdom, Kuraigana Island, in the Grand Line. He wakes up having been bandaged ridiculously by Perona, wondering where he is. As he awakes, he asked for his swords but Perona refuses to give him his weapons back. However, some brand of trust seems to have grown between them, as Zoro is later seen with his swords at his side and is casually walking through the ruins of the island as Perona floats overhead. He then encounters an unknown swordsman.
