A group of pirates lead by Alvida plunder a ship, only to find a barrel which contains a strange boy named Luffy. Luffy is on a mission to find the legendary treasure "One Piece" and he befriends the ship's cabin-boy, Coby, who actually wants to become a marine officer. Luffy defeats Alvida and the two journey on in search of crewmates.

Luffy and Coby arrive at Shell Island, a Marine base. They meet the bounty hunter Roronoa Zoro, held under arrest by the infamous marine, Captain Morgan, and his son Helmeppo.

Luffy convinces Zoro to join his crew, but they must first defeat Captain Morgan. After freeing the island from Morgan's oppressive rule, Coby is accepted as a marine while the other two continue on their journey.

Out on the sea, Luffy almost loses his hat and reflects on his past, and how a pirate named Shanks influenced him. Afterwards, Luffy meets Nami, and Buggy the Clown's men.

In order to save herself and steal a map to the Grand Line, Nami tricks Luffy into allowing her to turn him over to Buggy.

Mohji and Richie show up for revenge after Buggy's humiliating defeat in the previous episode, and Luffy meets a small dog guarding his master's store, even though he knows that he is long dead.

Enraged by the actions of Buggy's crew, the city's mayor rushes to fight Buggy himself, but the Straw Hat Pirates come to his rescue. Zoro fights Cabaji, despite still being wounded from his previous encounter with Buggy, while Luffy faces the clown pirate himself and Nami searches for the map to the Grand Line.

Buggy's link to Shanks is revealed, and when he rips the straw hat Shanks gave Luffy, his rage knows no bounds. Who will win in this clash between Devil Fruit users?

Nami form an alliance becoming the navigator of the crew, but not a full member yet. They arrive in Syrup Village looking for a suitable ship. On this island they know the liar Usopp, who also has ties to the Shanx.

When trying to convince his rich friend, Kaya, to give the Straw Hats a ship, Usopp is told to stay away from her by her caretaker, Klahadore. However, when Usopp and Luffy later see him conversing with a strange man, they learn of a plot to kill Kaya.

After learning of Captain Kuro's evil plan, Usopp runs back to the village to warn Kaya, only to find that after all his years of lying no one believes him.

Usopp resolves to keep his story of pirates attacking the town a lie by making sure none reach it. Luffy, Zoro, Nami, and Usopp then try to keep the Black Cat Pirates at bay.

The Straw Hats manage to take out most of the opposing Black Cat Pirates, so Jango orders the Nyaban Brothers to attack. Meanwhile, after getting hypnotized by Jango, Luffy gets himself stuck under the collapsed mast of the Black Cat Pirates' ship.

Captain Kuro himself arrives at the scene, and with Zoro too injured to fight, Luffy being incapacitated, and the other two being too weak to handle him, things seem hopeless. However, Kaya herself appears to bargain with Kuro.

While Usopp & Luffy fool around with the ship's cannon one day, Zoro dreams about his childhood and the promise he made to Kuina.

Zoro and Buchi (of the Nyaban Brothers) face off once again as Luffy and Kuro begin their fight. Usopp orders the Usopp Pirates to run away with Kaya, but Jango goes after them. A flashback reveals how Captain Kuro faked his death with Captain Morgan and how he became Kaya's butler.

As the fight between Luffy and Kuro is close to an end, the Usopp Pirates do their best to avoid Jango.

Kuro's ultimate attack, "Shakushi", attacks everything in the area, whether friend or foe, and Luffy becomes enraged by his lack of regard for his crew. Will Luffy's determination overcome Kuro's sheer speed?

With Usopp now in the crew and a new ship, the Going Merry, under their command, the Straw Hats head to an island said to hold a fabled treasure, only to encounter a strange man stuck in a treasure box that has also been looking for this treasure.

The crew meets Johnny and Yosaku, Zoro's former companions, and they set sail for the Baratie restaurant in search of a cook.

Sanji, a cook at the Baratie, helps a starving pirate named Gin. Luffy begins his job as a waiter to pay for the damage he did to the Baratie, 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.

It is revealed that Chef Zeff was a great pirate known as Red Leg Zeff. Gin explains the catastrophe the fleet met in Grand Line when they encountered Hawk-Eyes Mihawk, and Krieg attempts to take control of the Baratie.

As Nami steals the Going Merry, Mihawk has returned to finish the job, but Zoro challenges him to a duel in order to achieve his dream.

Mihawk leaves after defeating Zoro, so Krieg continues his invasion and has Pearl, one of his stronger crewmates, attack, and Sanji reveals his fighting skills. Meanwhile Johnny and Yosaku leave with Usopp and the wounded Zoro to go after Nami.

With Zeff held captive by Gin, Sanji has no choice but to take Pearl's hits, and he reflects on why Zeff means so much to him.

Gin finishes off Pearl, claiming that he wants to kill Sanji himself. Still wounded, Sanji faces Gin while Luffy attacks Don Krieg.

When Gin refuses to kill Sanji, Krieg uses a poison gas on him. Luffy seems to have the advantage in the fight until Krieg pulls out his explosive Battle Spear.

Even after taking several hits from the Battle Spear, Luffy refuses to give up.

After the battle, Gin decides to go back to the Grand Line with Krieg despite still being poisoned, and Sanji makes the difficult decision on whether to stay or to go with Luffy just as Yosaku comes back with news that he knows where Nami is.

The crew chases after Nami, who stole their ship, and Yosaku takes time during the trip to explain about Arlong and his Fishmen to Luffy and Sanji. Meanwhile, Usopp, Johnny, and Zoro arrive at the island Nami docked at.

Zoro is captured by the fishmen after Usopp and Johnny ditch him, and it's revealed that Nami was part of Arlong's crew the entire time. When a group of Fishmen attack Cocoyashi Village, Usopp comes to the rescue.

After Zoro escapes with Nami's help, she tries to prove her loyalty to the Arlong Pirates by appearing to kill Usopp. Meanwhile, Luffy's group finally arrives at the island.

Johnny tells the others about Nami killing Usopp, and Luffy does not believe them until Nami appears herself and confirms it. She tells them to stay out of her business and leave without her, but Luffy stubbornly decides to stay on the island. Usopp returns, revealing that Nami only pretended to kill him, and Nami's sister, Nojiko, starts to explain why Nami is acting the way she is.

Nojiko starts her story about Nami's childhood and their adopted mother, Bellemere. Despite being poor and none of them being related by blood, they had a happy life.

Nojiko continues her story, explaining how their life was ruined when the Arlong Pirates first took over the village.

When a marine officer under Arlong's pay confiscates all the money Nami stole over the years, in order to one day buy the village from Arlong, the villagers decide that enough is enough and fight back, despite Nami's pleads that they do not and that they'd all be killed. Upon seeing Nami's sorrow, the Straw Hats head for Arlong Park.

The Straw Hats face the Fishmen themselves as the villagers watch from the sidelines.

Arlong has trapped Luffy in the ocean and Zoro faces the six-sword wielding octopus Hatchan.

With Hatchan defeated, two of the fishmen battle Sanji and Usopp. Things look grim for Sanji as he attempts to face Kuroobi underwater, and Usopp gets the chance to prove that he too is a brave warrior.

Arlong's officers have been defeated, but Sanji and Zoro prove to be no match for Arlong in their current state. However, with Luffy finally free, he just may be able to defeat the "most wicked man in the East Blue". Meanwhile, Nami finally gathers the courage to face Arlong.

Luffy returns to the fight, and the battle with Arlong versus Luffy begins.

The battle spreads into Arlong Park itself and Arlong is no longer holding back.

Arlong's reign of terror is over, and no one has anything on their mind except to party. As the crew celebrates, Nami reflects on her hometown and decides to officially join the Straw Hat Pirates.

As a result of defeating Buggy, Krieg and Arlong, Luffy now has the highest bounty in all of East Blue. News quickly spreads to Shanks, who celebrates Luffy's arrival into the world of pirates by partying with Mihawk, despite already being severely hungover.

After his fight with Luffy, Buggy was sent flying to another island with several body parts missing. Thus, Buggy begins his journey to find his crew and his body parts, making some unlikely friends.

With Buggy assumed to be dead, his crew fights over who will be the new captain, only to be captured by a tribe of cannibals.

The crew arrives at the last large town before the entrance to the Grand Line--Loguetown, the place where Gold Roger was both born and executed, where they stock up on supplies and sightsee. As Luffy heads for the execution platform where Roger was killed, old enemies are searching for him.

While searching for new swords to replace the ones shattered by Mihawk, Zoro meets a woman named Tashigi, who looks exactly like an older Kuina, who then helps him look.

Usopp manages to anger the daughter of bounty hunter Daddy the Father, and finds his own life at stake. When Daddy discovers that Usopp is the son of Yasopp, the only man to beat him, he challenges him to a duel.

In order to win a rare fish, Sanji enters a cooking contest and faces a woman named Carmen.

Luffy arrives at the execution platform only to be caught in a trap by Buggy and Alvida.

Miraculously saved from death by an unnatural green gust and a lightning bolt to Buggy, the Straw Hats rush out of Loguetown, only for Zoro to be stopped by Tashigi and Luffy to be stopped by Captain Smoker.

On a stormy night a girl called Apis escapes from the Marines and arrives at Straw hat's ship, but the girl upon knowing that they are pirates begins to hide some of the reasons which she is being wanted by the Marines. As the Straw Hats escape from the Marines, they get caught in the Calm Belt.

After escaping the clutches of the Marine fleet, the Straw Hats soon find themselves in an equally dangerous predicament - stranded in the Calm Belt!

The Straw Hats want to return Apis's dragon to his nest, but the Marines have them surrounded. Looks like it's time for another daring escape!

Even for Nami, finding the dragon's lost island proves to be tougher than looking for a needle in a haystack - or at the bottom of the ocean.

Zoro is left fighting with Eric while Luffy and the gang run to the ship in order to get to Lost Island, but only find more problems.

At last Admiral Nelson has seen through the ambitions of Eric, but takes it a little too personally and now the mystical dragon's life is in danger.

With his last breath, Ryuuji calls all his fellow dragons, and the Lost Island re-surfaced. Meanwhile Luffy takes out Admiral Nelson and his gang.

After leaving Warship Island the Going Merry is now towards the Grand Line, and the crew now returns to the Great Adventure.

Upon entering the Grand Line, the ship is swallowed by a giant whale, inside of which they discover a strange place. In addition, they are not the only ones there.

After hearing the story of Laboon the whale, Luffy comes up with a clever solution to his problems. From Laboon's caretaker, Crocus, the crew learns more about the Grand Line and how to navigate through it, since compasses are useless there.

Luffy and friends arrive at Whisky 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, who does not realize the town is full of bounty hunters, engages in a battle with Zoro after he discovers that Zoro attacked the townsfolk, while Mr. 5 and Miss Valentine head for Princess Vivi.

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 second strongest member of Baroque Works and partner of Crocodile.

As Luffy and his crew are sailing in the Grand Line, Koby and Helmeppo are stuck doing odd-jobs for the marines back in East Blue, and encounter Vice-Admiral Garp.

Vice Admiral Garp mentors Koby and Helmeppo to become marines.

Luffy and friends land on Little Garden, a prehistoric island inhabited by dinosaurs and giants.

Nami and Usopp meet a giant named Brogy, while Luffy and Vivi encounter Brogy's rival, Dorry. The Straw Hats little suspect that Officer Agents of Baroque Works are on their tail.

Dorry, critically injured by exploding ale, blames the Straw Hats. Luffy is enraged that someone would pull such a cowardly trick to sabotage the giants' honorable duel.

Luffy tries in vain to convince the injured Dorry not to fight Brogy. The Officer Agents who sabotaged Dorry's ale further tamper with the giants' duel.

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.

Luffy attempts to rescue his friends but only accelerates the deadly waxing process. To make matters worse, Miss Goldenweek interferes and reveals her own terrifying ability.

Usopp frees Luffy from Miss Goldenweek's control. With Karoo's help, Usopp and Luffy rescue the others, who take on Mr. 5 and Miss Valentine. Luffy and Karoo pursue Mr. 3 and Miss Goldenweek into the forest.

After having a pleasant chat with Mr. 0 and encountering the "Unluckies", Sanji retrieves an Eternal Pose for Alabasta. The crew leaves Little Garden and sets sail for Alabasta.

Nami is sick, but the crew doesn't have a doctor to help her.

While looking for a doctor, the crew meets the pirate Wapol, who attacks them, but only makes Luffy send him flying. Meanwhile Smoker manages to intercept the conversation between Mr. 0 and Sanji and plans to go to Alabasta. Back with the crew 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. Luffy and Sanji must take Nami to the island's sole doctor who lives on a mountain-top. Vivi and Usopp discover the past of the island, and about the pirate Wapol from Dalton.

While Sanji and Luffy fight off the wilderness, the islander's worst nightmare turns true, as Wapol returns to the island. The doctor is discovered to be on the other side of the island, and Usopp, Vivi and Dalton rush to find her. Dalton however returns as he hears of Wapol's return.

Dalton faces Wapol, but only gets himself hit by arrows thrown by his former comrade Chess. An avalanche stops the battle, but injures Sanji. Luffy must carry both Nami and Sanji to the doctor, and begins his ascent.

The Lapahn help Luffy escape from Wapol, giving him enough time to climb to the castle where doctor Kureha lives. Vivi, Usopp and Zoro deal with the king's army in order to save Dalton. The recovering Nami meets a strange creature.

Nami asks Chopper to join the crew, but he isn't interested. Kureha tells Nami some of what was Chopper's background. After realizing the abilities that Chopper has, Luffy is eager to make him join the crew.

Doctorine continues to tell how Chopper lived his life and how the quack doctor Hiruluk took care of him.

More of Chopper's past is revealed, including the fate of doctor Hiruluk and Wapol's cruelties as the king. Meanwhile, Wapol reaches the castle where the crew is residing.

Wapol is determined to bring down Hiruluk's flag, and to do that, he engages Sanji, Luffy and Chopper in a fight.

Chopper demonstrates the abilities of Rumble Balls when fighting Chessmarimo. Dalton is uncovered from the avalanche.

After trying every trick in the castle, Wapol is finally hunted down by Luffy. 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.

Chopper joins the Straw Hat crew as they continue their journey to Vivi's homeland.

Crocodile appears to stop rampaging pirates. Luffy and his crew meet Mr. 2 Bon Clay who shows off his devil fruit power and Vivi sees a shocking sight.

Luffy separates from the rest of the crew, right after arriving at Alabasta's port city of Nanohana. The crew dons disguises while Luffy learns of Dance Powder.

While in Nanohana, the Straw Hats encounter Smoker and Tashigi. A powerful pirate named Portgas D. Ace appears.

Ace fights Smoker while the Straw Hats run for their ship. Luffy reunites with his brother, who has joined the Whitebeard Pirates after leaving home, and is searching for a former crewmate named Blackbeard who killed a fellow member.

Ace decides to travel with the Straw Hats, as he is hunting for a man known as Blackbeard.

After leaving Erumalu, the Straw Hats plus Vivi & Ace continue through the desert, facing the many dangers of it.

Nami and Vivi found themselves an easier way to travel in the desert and leave all men behind.

After hearing that a small village has fake Rebel Army bodyguards that have been keeping peace, Vivi asks the men of the crew to test if they're worthy of staying.

Still trekking through the Alabasta desert, the crew beats up a giant desert scorpion for lunch, while Vivi tells Nami about her past and her friendship with Kohza.

Ace fights against a bounty hunter, who claims to have defeated Blackbeard, although this was a lie to lure Ace out and challenge him in order to inspire his children to follow their dreams.

Zoro, Chopper and Luffy manage to get themselves lost and stumble across some huge underground ruins.

Baroque Works plan starts to take effect, and for that, the Number Agents gather to meet Mr. 0. Meanwhile, 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.

In Yuba, Luffy learns that Toto was entrusted by Cobra to watch over the land and figures out a way to stop the sandstorm.

After the struggle, Vivi decides to go after Crocodile with the Straw Hats. The crew travels to the city of Rainbase, but run afoul of Smoker and Tashigi.

Most of the Straw Hats, along with Smoker, are trapped by Crocodile. Vivi reunites with the royal guardian Pell, but is captured by Miss All-Sunday. Crocodile reveals his invincible Devil Fruit power.

Baroque Works' plan to take over Alabasta is set in motion.

Most of the Straw Hats are helplessly trapped as Vivi tries desperately to get the key to their cage. but fails. Crocodile is contacted by someone known as "Mr. Prince."

The identity of "Mr. Prince" is revealed.

After escaping from Rain Dinners, the Straw Hats and Vivi cross the desert to Alubarne, where the final battle will take place.

Luffy is left for dead by Crocodile, but is helped by the mysteríous Miss All-Sunday. The rest of the Straw Hats reach Alubarna.

The revolution is on the verge of starting and the crew comes out with a plan that could stop it.

Vivi tries to call out to the Rebel Army, but fails because of a Baroque Works infiltrator in the Royal Army interferes.

Things look hopeless for Usopp & Chopper as they continue to suffer from every attack that the Mr.4 team makes. However, the tides may be beginning to turn as Usopp learns what it truly means to be a man.

Albeit severely beaten and bruised, Usopp and Chopper have finally defeated the Mr.4 team. However, Mr. 2 has figured out Sanji's weakness.

Though Mr. 2 discovers Sanji's weakness, Sanji still defeats his opponent after an evenly-matched fight. Meanwhile, before Vivi could give the word to blow up the palace, Crocodile appears.

Nami faces off against Miss Doublefinger and tries to figure out her new weapon that Usopp made, the Clima-Tact.

While Crocodile reveals to Vivi about the ancient weapon Pluton, Nami attempts to defeat Miss Doublefinger with her most powerful attack: The Tornado Tempo.

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 cannot cut. As Zoro nears death, he must discover the secret to "the breath of all things".

When Vivi reveals Crocodile's plan to Koza, he attempts to stop the fighting, but is shot. Crocodile reveals that he has set up a massive bomb in the city.

As Koza tries to stop the Rebel Army, both sides are once more fighting due to the intervention of Baroque Works. Vivi is thrown to her certain death when Luffy saves her and challenges Crocodile to a second round.

Luffy fights Crocodile with more success this time by using water, but still loses this round. Meanwhile, the other Straw Hats hurry to locate the bomb before it goes off. Nico Robin forces the king to take her to the tomb where the Pluton Poneglyph is hidden.

Crocodile joins Robin in the tomb, and orders her to translate the Poneglyph. Robin tells him that Pluton was not mentioned and that it was only about history, but Crocodile figures out that she was lying and stabs her in response. When Luffy recovers from the last round of fighting, he chases after Crocodile into the tomb.

Luffy fights with Crocodile by using blood on his fists. Meanwhile 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 Alabasta.

Luffy defeats Crocodile by punching him through solid bedrock. When Crocodile falls, the rain-drops calm the soldiers.

Now that the battle has ended, the outcome is tallied. Igaram appears with proof of Cobra's innocence, as well as Koza telling everything. Tashigi and Smoker both are rewarded for taking on Crocodile, but neither one of them believes that is right, considering the Straw Hat pirates did all the work.

Luffy is rescued from the collapsed tomb where he fought Crocodile and brought into Cobra's palace to rest. When he awakens, 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 Kurei and his crew attempt to protect the Straw Hats from Hina.

The Marines fail again to catch the Straw Hats. After escaping from Marines, Nico Robin (Ms. All Sunday) appears from inside of Straw Hats ship. She manages to persuade the crew to let her join. Pell is seen at the end standing over his own grave.

After their adventures in Alabasta, the crew come upon another deserted island and split up tasks amongst themselves. Chopper is left in charge of guarding the ship, and he reminisces about the day he first made the rumble ball and his first patient, Dr. Kureha, while spending some time with the newest crewmember: Nico Robin.

A weird salesman is fished out of the water and onto the Going Merry, and Nami buys a ton of "1000 year paper" from him to draw her sea maps. However, that's not going to be easy with the rest of the crew goofing off as usual.

The Going Merry runs into several Marine ships in some fog, and the Straw Hats meet a trainee Marine chef named Tajiyo. Sanji helps him out of a bit of cooking trouble.

The crew stops on an island that's having its annual fireworks festival; Usopp meets a young fireworks-maker named Kodama and helps her achieve her dream.

Zoro has a flashback about the time when he first met Johnny and Yosaku, and faced off against Bandits and, Dick.

After escaping from several Marine ships, the Straw Hats land on an uncharted island and meet an old man named Zenny. Chopper finds out that, because of his bad heart, Zenny probably only has three days to live.

The Straw Hats help Zenny out, hoping to make his last days good ones; they learn about Zenny's past as a money lender, and his dream of becoming a pirate. But Zoro realizes that Zenny has outlived Chopper's predictions and so the straw hats decide that, after helping him finish his pirate ship, they will leave the island.

Zenny decides to follow his dream and become a pirate, despite his age. He helps the Straw Hats out of trouble with the Marines, and then they part ways.

On Ruluka Island, some of the Straw Hats make enemies of the Mayor and his men, who have placed high taxes on everything. Robin, Usopp, and Luffy meet Professor Henzo, who's doing research on the island's rainbow mist. When some of the mist shows up, Henzo borrows the Going Merry to go explore it.

The inside of the Rainbow Mist full of wrecked ships and treasure, and is guarded by five kids. The kids are actually friends of Henzo's that got lost in the mist over 50 years ago.

Henzo, his friends, and the others try to find a way out of the ship graveyard. Meanwhile, the Mayor and his men let the information about the Rainbow Mist slip to the remaining Straw Hats still on Ruluka.

Luffy accidentally propels himself and Rapanui to the end of the mist. Nami appears in the ship graveyard with a rowboat full of treasure and a string connected to the real world, which are both stolen by Wetton's subordinate. The Mayor uses the Rainbow Tower to make a bridge to the Rainbow Mist.

The Going Merry escapes from the Rainbow Mist, getting badly damaged on the way. The Mayor gets arrested by a bunch of powerful marines that turn out to be older versions of Henzo's friends, who were thrown 50 years into the past by the Rainbow Mist's collapse.

Nami's log pose begins to point to the sky, and the crew finds a map 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. Meanwhile, Ace suddenly shows up on Buggy's ship; Buggy does not let any of his men attack Ace, fearing Whitebeard's retribution.

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 Shoujou, another salvage monkey.

The Straw Hats meet with Mont Blanc Cricket on another part of Jaya; Cricket is a descendant of Montblanc Noland, 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 southbird to point them toward the point where the stream will erupt from the ocean.

While the Straw Hats are looking for a Southbird, 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.

Luffy takes out Bellamy with a single punch. Meanwhile, the world government heads are concerned over Whitebeard, Shanks, and Luffy. The marines try to decide who will replace Crocodile as a Shichibukai - one of Blackbeard's crew shows up uninvited and nominates his captain.

The Going Merry is refitted by Masira and Shoujou 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. Usopp almost falls out of the Going Merry but is saved at the last minute. The crew is also attacked by a mysterious looking warrior, but is saved by the Knight of the Sky. Finally, they arrive at the border which transports them to the upper realm, Skypiea.

As the crew arrives in Skypiea, they are greeted by Conis and her pet Su. Both she and her father start explaining how the life in Skypiea is and how the different Dials work.

Nami finds out what should happen to anyone who enters the forest. Meanwhile, the rest of the gang are waiting for the wind to change but are rudely assaulted by Skypiea's police who are going to carry out Heaven's Judgement.

The Straw Hats have some problems with the local justice enforcer force called "The White Berets."

While trying to escape from Sky Island, Robin, Chopper, Nami and Zoro are held hostages by God Enel.

Conis leads Luffy, Usopp, and Sanji to a boat to get to Upper Yard, but she tells them it is a trap and almost gets hit by "Heaven's Judgment".

Luffy, Usopp and Sanji finally enter Upper Yard, only to find out that the whole road is trapped heavily, but at last they arrive at the Ordeal Gates. Meanwhile Robin, Zoro, and Nami go out to explore Upper Yard while Chopper stays behind to guard the ship.

Luffy, Sanji, and Usopp enter the Ordeal of Balls gate and encounter the Priest Satori.

Usopp, Sanji and Luffy fight Satori, but the power of Mantra seems to be too strong.

Chopper, threatened by priest Shura, blows the whistle for Gan Fall to come, but before he can arrive, Priest Shura assaults Chopper and begins destroying the Going Merry.

Gan Fall cannot handle Shura and lost the battle. Meanwhile, Satori is finally defeated by Luffy and Sanji.

Chopper is saved by a bunch of giant Southbirds, who tell him that Gan Fall was actually God. Nami, Zoro and Robin discover the reason why Upper Yard is a soil island: It was once part of Jaya, and this is the part that Liar Noland saw. Meanwhile the Shandia attack Upper Yard.

The Shandia attack on Upper Yard has started. The crew is finally reunited, and everyone speaks up about what has happened. Chopper takes care of Gan Fall, and the pirates plan to steal the gold on the island.

After befriending a wolf pack, Gan Fall tells the crew a little more about the history of Upper Yard.

Enel takes away the limitations of the priests. Also, Usopp witnesses a mysterious person fixing the ship; the next day Merry is found to be back to her original form. After getting her off the altar, the pirates plan out their course of action.

A giant python makes Luffy, Robin, Chopper and Zoro split while going to the ruins at the south.

Wyper takes out Shura and tells his goal to the Shandia, and Enel speaks up about how many people will be alive by the end of his plan.

Zoro fights the Shandia warrior Braham, and defeats him with Ittoryu (one sword style) 36 Pound Cannon technique.

Luffy fights Wyper, but after some time, he falls into some underground ruins. Meanwhile, Enel appears on the Going Merry and after telling that his true goal was the City of Gold, he takes out both Usopp and Sanji; then he vanishes and leaves Satori's brothers: Hotori and Kotori to avenge him.

Chopper is attacked by Gedatsu, who turns out to be a complete moron, and eventually defeats him, sending him plummeting to the Blue Sea. Conis and Pagaya help Aisa, and head to Upper Yard.

Enel defeats several members of the Shandia Tribe. Meanwhile, Gan Fall and Nami start and finish their fight with Kotori and Hotori. Hotori is defeated by Nami while Kotori is defeated by Gan Fall.

While Robin is looking at some ruins she found, Yama, The Chief Enforcer, attacks her. Yama is easily defeated by Robin. Later, she discovers the legendary city, Shandora.

Priest Ohm appears and starts fighting everyone.

At the Upper Ruins, the fight between Ohm, Zoro, Gan Fall and Wyper begins. When Nami appears, she is swallowed by the giant python, along with Gan Fall and Aisa.

Ohm makes matters worse, creating a barbed wire cage around the area. Laki is knocked out by Enel, and Nami, Aisa, and Gan Fall find out why the python was rampaging so much.

Zoro finally defeats Priest Ohm with his 108 Pound Cannon technique. Meanwhile Pagaya and Conis hear the terrible truth about the goal of Enel: to eradicate every person in the sky.

Enel appears only to reduce the group as close to his prediction as he can.

Enel counterattacks Gan Fall and lands a finishing hit. He then knocks out Robin as she tries to manipulate him. Zoro impresses Enel with his power but is easily beaten, while trying to make him pay for what he did to Robin; but it takes Wyper with a secret weapon to take Enel down.

Enel defeats Zoro and Wyper. Upon seeing this, Nami follows him to a cave where his ark, Maxim, is. Luffy finally gets out of the snake, along with Aisa, only to find out the outcome of the fight against Enel. When Aisa tells him that she knows where he is, he asks her to take him there.

Luffy and Enel start fighting. Conis tells the dangers of staying in Sky Island to the other Skypieans.

The fight between Enel and Luffy continues with Enel starting a machine that would bring the death of Skypiea: Deathpiea.

Luffy falls from the ark. Nami starts fighting Enel while Sanji and Usopp try to rescue her.

Usopp and Sanji split up to rescue Nami, but the first one to get on deck is Usopp.

The history of Noland and Kalgara is told, as a flashback from Wyper.

Noland and Kalgara are enjoying themselves, as well as the villagers and Noland's crew, but that changes one day, as the villagers start hating their new friends.

The cause of the hatred is discovered and explained. Meanwhile, Kalgara vows to meet Noland again.

Angel Island is destroyed by Enel's attacks. Luffy decides to go and ring the golden bell before Enel takes it away.

Nami finds out a way to get to Enel, by cutting down Giant Jack. Wyper finds out from Robin that Noland has a descendant that is searching for the Gold City, and that's the reason why Luffy wants to ring the Golden Bell.

Luffy battles Enel. Battle for Skypiea!

The 400 year war on Sky Island comes to an end. Montblanc Cricket and the Masira Brothers hear the Golden Bell ringing and realize that the Gold City was always in the sky. Enel, who was thrown to the Blue Sea heads out to the Fairy Vearth (the Moon). The Sky People (both Skypieans and Shandia) celebrate the end of the war with a great bonfire.

Robin deciphers the poneglyphs on the Golden Bell and realizes how to find the Rio Poneglyph. She also discovers that the poneglyphs on the Bell were written by Gol D. Roger, who could understand poneglyphs, who had discovered the Rio Poneglyph, and had once visited Skypiea. Soon afterwards, the Straw Hats steal a bunch of gold from the Giant Anaconda's belly and they begin to leave Skypiea.

The Golden Bell rings as the Straw Hats are going down to the sea, meaning that they are welcome and are deeply thankful for what they did. When the ship finally rests on the sea, problems appear, as the ship has landed in a Marine base.

The Marines are convinced the Going Merry is a ghost ship after it crashes inside their fortress from above. The crew members are scattered around the premises.

In disguise, Sanji shows the Marine chefs the proper way to prepare a meal.

Zoro is taken prisoner as Chopper and Nami assist a nervous doctor in treating injured Marines.

Robin and Usopp both disguise themselves as the same visiting inspector, and Usopp is thrown in the brig with Zoro. Luffy and Sanji are discovered by Jonathan after a slight mishap.

The real Inspector is thrown in the brig with Zoro and Usopp, while Sanji and Luffy race to rescue the two while avoiding detection.

Sanji and Luffy, after freeing Usopp and Zoro, try to escape Navarone. As the Burning Soul combat unit is deployed, Dr. Kobato leads Nami and Chopper to the docks.

The crew meets at the docks and are surrounded by Marines. Using Nami as their fake hostage, they trick the Marines into letting them back on the Going Merry.

The crew disguises the Going Merry as a Marine ship so they can get their treasure back. With the gold, they decide they’ll hire a shipwright.

Usopp splits up the crew into two teams: the gold retrieval team and the waver retrieval team. Inspector Shepherd decides to catch Luffy on his own.

Sanji, Zoro, Usopp, and Robin continue to search for their treasure. Luffy leads Nami to the captain’s quarters where they retrieve their gold.

The Going Merry is grounded during a period of low tide and Jonathan believes they’ve reached “checkmate”. They cleverly use the impact dial to boost the ship and the breath and flame dials to inflate the octopus balloon again so they can escape.

Luffy and company come across a mysterious pirate ship after trying to escape a giant wave. Soon, they arrive on an island inhabited by strange animals. Going Merry is captured by the Foxy Pirate crew.

After Tonjit re-unites with his horse, they are soon attacked by Captain Foxy and his subordinates, who challenge Luffy in a Davy Back Fight, a contest of pirates where the stakes are members of the crew.

The first round of Davy Back Fight involves a race around the island with tiny boats. Zoro's and Chopper's boat is eliminated.

With only Luffy, Nami, and Porche's boat remaining, it's an all out war to the goal, but after Foxy exposes his Devil Fruit powers, Porche wins and takes Tony Tony Chopper from Luffy. The second round prepares to start.

Without Chopper, Sanji and Zoro must face the Foxy Pirates in a ball game, but are hampered by their blatant cheating and the crooked referee.

The bickering rivals Sanji and Zoro manage to overcome the opposing team by working together. Luffy chooses Tonjit's horse, Shelly over Chopper.

The Straw Hats face Foxy a race around a giant ring on roller skates.

Thanks to to some quick planning, the Straw Hats win the race.

With Luffy's victory, he takes Chopper back, but foolishly accepts another challenge by Foxy.

Foxy decides to take Robin from Luffy this time because of her Devil Fruit ability. The next match is a race to the top of the island.

With Chopper gone again from Luffy's crew, Luffy and Foxy face off in the final game: a battle of brawn aboard Foxy's ship.

Luffy continues to battle Foxy with the odds not in his favor, and the fight continues inside Foxy's ship.

Luffy manages to finally defeat Foxy by using his ability against him. After dismissing his new crewmembers, the Straw Hats leave in search for a shipwright.

A mysterious figure appears during the night and steals the memories of the crew. In the morning, Robin is the only one who remembers the Straw Hats adventures together. Her attempts to keep the crew together fail as Nami and Zoro go separate ways.

Robin suggests that only those who were sleeping lost their memories. Luffy and the others then remember seeing the mysterious boy who played some kind of flute. Later that night, they discover the boy outside and Luffy tries to fight him. At the last second, he proclaims his memory has returned.

During the night, Usopp, Chopper, and Sanji question what brought them to the Going Merry. In the morning, Usopp builds them a raft and they sail to the island where they meet Nami again. Meanwhile, the boy sets his sights on Zoro.

On their way to "The Palace of the Sea God" Robin's group meets an entranced Zoro. It looks like Zoro wants to fight so Luffy urges the others to keep going without him. They apprehend the kid but the whistle was what was really stealing their memories. Zoro returns, still entranced, but Luffy's nowhere to be seen.

Luffy returns and knocks some sense into Zoro. Cornered, the sea horse spreads illusions of the people in their memories to distract them. It steals their complete memories and claims that it has become a Sennenryu. Luffy defeats it and returns all the memories but the townspeople are convinced they are the memory stealers.

Luffy rescues Foxy, Hamburg, and Porche from a storm at sea. When they reunite with the Sexy Foxy ship, they find it captained by somebody new. Foxy accepts a Davy Back Fight in order to regain his ship and crew. Donning the afro once again, Luffy vows to defeat the captain.

Once Foxy wins back his crew, he captures the Straw Hats. Nami and Luffy fight Foxy and although he's defeated, his crew accepts him back. Later, they sail to an island where they meet someone Robin knows: a Marine named Aokiji.

The man they met, Marine High Admiral Aokiji, appears to be incredibly lazy. He first displays his Devil's Fruit ability by freezing the sea so some deserted people can get off the island. Unfortunately, he's determined to catch Robin. Luffy, Sanji, and Zoro attack but they seem to be no match.

Robin is frozen by Aokiji and Luffy tells the others to escape with her. In the Going Merry, Usopp and Chopper try to thaw her in the shower. Luffy gets defeated (frozen), but his life is spared as Aokiji believes he must repay the debt the marines incurred from Crocodile's defeat at Luffy's hands. With the crew defrosted, they continue sailing as usual. Zoro spots the giant frog they heard about and they chase it to an island with a lighthouse, but it appears they'll sink before they get there.

After the Going Merry narrowly escapes being hit by a "sea train", the crew meets an old woman, Kokoro, and her granddaughter, Chimney. Kokoro gives Luffy a map to Water Seven. Luffy, Nami, and Usopp buy boats driven by sea monsters called "yagara".

Luffy, Nami, and Usopp get strange greetings from the residents and they get to experience the roller coaster-like channels of Water Seven. Luffy find out that some pirates had been beaten at the hands of some powerful craftsmen; the Galley La Company. Chopper loses Robin and some strange new people threaten Zoro back on the ship.

The people who attacked Zoro reveal themselves to be the feared "Franky Family", though they're no match for Zoro. Luffy have their gold exchanged for cash. After, they meet a man who resembles Usopp, Galley La's carpenter employment foreman, Kaku. Usopp's cut of the money is stolen by the Franky Family.

Paulie makes his debut when he retrieves Usopp's stolen money as he runs from debt collectors. Kalifa shows Luffy, Nami, and Usopp around Dock No. 1 and tells them how Iceburg founded the Galley La Company. Kaku returns from the Going Merry and tells them that their keel is irreparably damaged.

Luffy refuses to believe that Galley La cannot repair the Going Merry. The two soon realize that not only is Usopp missing now, but the two brief cases that were returned to them are empty. Nami decides to head to Franky House and finds Usopp on the way in a pitiful state. As she heads back to the ship for help, Usopp goes to the Franky House himself.

Luffy, Sanji, Zoro, and Chopper follow Usopp's bloody trail to the Franky House, where they find him passed out in front. The four of them challenge the Franky Family only to find out that their real target, Franky himself, is gone and has taken the money with him.

Once they're back on the ship, Luffy has to finally tell Usopp that the Going Merry can no longer be repaired and that they've chosen to get a new ship without him. Usopp believes that Luffy has abandoned the dignity of their ship and says he's leaving the crew. That night, he challenges Luffy to a duel.

Usopp fights Luffy in order to decide who keeps the Going Merry; he fights harder than he's ever fought before. Luffy actually seems to pose no threat but all the while, he's remembering what great friends they used to be, sailing together on the same ship. Even after taking a harsh beating, Luffy defeats Usopp. They leave Usopp and the ship behind.

The Strawhats get themselves a hotel room. Nami finds the crew on the roof with urgent news: Iceburg has been shot. As the Galley La Company frantically search for answers, Nami and Luffy decide to check on his condition – only to be met by closed gates. Franky appears then to exact his revenge – with style.

In the streets outside of the hospital, Luffy fights Franky. Inside, Iceburg recalls seeing Nico Robin and another tall man before he was shot. The Galley La company run outside and stop Franky and Luffy and tell them that they suspect the Strawhat Pirates of the crime.

The Galley La Company continues to fight Luffy and Franky is enraged that they've stolen his opponent. An incredibly high tide called the "Aqua Laguna" is coming and Chopper and Sanji rush to warn Usopp. Luffy raises some chaos in order to meet with Iceburg and he demands to know what's happening. Iceburg says he wants to see Robin one more time.
