Monkey D. Luffy/History/Straw Hats Return

The Reunion


After two years of training, Luffy is greeted by Hancock, Marigold, Sandersonia, Marguerite and Nyon who are prepared to take him back to the Sabaody Archipelago. Luffy turns to a group of extremely large animals and tells them to back off from his friends. Sandersonia remarks that Luffy has become the "Boss" of the entire island. Luffy then reveals that Rayleigh had left him 6 months earlier than planned as Luffy had learned all that Rayleigh could teach him about Haki. When Hancock brought up the idea of becoming Luffy's wife, Luffy bluntly refuses before thanking her. Luffy then put his straw hat back on, a symbol of the pirate Straw Hat Luffy returning from his vacation. The group then sets off towards the Sabaody Archipelago.

After reaching somewhere close to Sabaody Archipelago, Hancock gives Luffy the cloak she wore to Impel Down, a fake moustache, and a large bag full of supplies. Luffy then leaves the Kuja ship on a small boat. While searching for his crew on Sabaody Archipelago, Luffy accidentally knocks over the impostor version of himself. The impostor demands for Luffy to stop, and threatens him to beg for forgiveness. Luffy just apologizes again and keeps on walking. This causes the fake to fire at Luffy who quickly dodged the bullet. He then knocked out all the impostors using Haōshoku Haki and keeps on walking, following the direction in which the Vivre card is going.

Luffy decides to put on the fake mustache that Hancock gave him. He soon meets Fake Zoro and Fake Sanji, who he believed to be the real ones and so followed them back to Fake Luffy. As Luffy follows the fake members, he is led to fake Luffy on Grove 46 and brought up to a podium where the fake crew is at. While the fake Luffy is about to announce his revenge on Luffy, the Marines followed by Pacifistas and Sentomaru attack. While the recruits of the fake Straw Hats are beaten, the real Luffy is revealed to everyone present after Sentomaru takes out the impostor (who turned out to be a pirate called "Three-Tongued" Demalo Black, who worth a mere 26,000,000) and orders one of the Pacifista to locate him.



Luffy dodges a laser attack from a Pacifista with Kenbunshoku, and takes out the Pacifista in one single Busoshoku Imbued Jet Pistol - this indicates to all the spectators, to their surprise, that he is indeed the real Luffy. Zoro and Sanji greet him, after the two take out a Pacifista together. As Luffy begins to escape from the Marines with the real Zoro and Sanji he sees Rayleigh, and says farewell and goodbye to him and then stated "I'm going to be Pirate King" once more, and sets off to Grove 42.

As the Monster Trio head back to the Thousand Sunny, they found Marines blocking their way only for Perona to come and fend off the marines with her Negative Hollow. She then informed the trio that the Marines were coming by the sea. They were then picked up by Chopper and a giant bird, who quickly took them to the ship. Luffy then had a chance to breifly admire Franky's new body before they were attacked. Hancock and the Kuja Pirates came to Luffy's aid by intercepting the attacking Marine ship.



When Luffy revealed that he knew her, he gained the envy of Sanji while Nami and Usopp were suprised that Luffy was sent to Amazon Lily. They then started making preparations to leave with Nami explaining on how a coated ship works. Luffy said to his crew that he has a lot to talk about and thanked them for following his two-year plan. Luffy then states that it's time to set sail for Fishman Island. With the Marines held back by the Straw Hats' new allies, the crew submerged and head for Fishman Island.

The Undersea Voyage
As the Sunny submerges, Luffy gets excited and marvels at the scenery around them. He and Zoro then try to catch some fish but are beaten down by Usopp and Chopper.

When Sanji suddenly flies out of the bubble due to his nosebleed because of his weakness towards women, Luffy grabs him and pulls him back in. After Nami further explains about the coating, Luffy and Zoro once again try to catch some fish, but again they are beaten down by Usopp and Chopper. Seeing that Sanji is out of commision, Luffy then decides to share the Bentos he got from Hancock with the rest of the crew. Franky then reveals to the crew that the one who ensured the safety of the Sunny, along with Hachi and Duval, during the last year was Bartholomew Kuma. He states that he found him sitting in front of the Sunny, and later Rayleigh told him that Kuma made a deal with Vegapunk to input a mission to protect the ship until a Straw Hat returns. As the crew wonders about Kuma's true intentions, Caribou and his crew are following behind them from a distance, trying to catch up.

With their seacow, the Caribou Pirates eventually caught up with the Straw Hats and they prepare for battle. Caribou quickly sets foot on the Thousand Sunny. However, before his crew can follow, his seacow, which turns out to be Mohmoo, fled in fear after seeing Luffy, Nami, and Sanji taking the rest of the Caribou Pirates and leaving Caribou alone. The Straw Hats then tie up Caribou.



When the crew travel through the deep currents and encounter a sea monster known as the Kraken, Luffy decides to tame it and have it pull their ship much to the others' dismay. Luffy then realizes that they are under water, which is a problem for him. Caribou then introduces Flutter Kick Coating to the crew. Luffy, Zoro, and Sanji then use it and fight the Kraken out in the sea. Luffy scolds Zoro for cutting some of the Kraken's tentacles before knocking it out with his Gomu Gomu no Elephant Gun. The Monster Trio defeat the Kraken, but because they are not wearing life-lines, they got separated from the ship as it goes down the "underwater waterfall". Later Luffy successfully tamed the Kraken and named him Surume. Unfortunately, Luffy and Sanji's bubbles had broken, so they had to share Zoro's coating. After some searching, the Monster Trio eventually found the Thousand Sunny and the rest of the Straw Hats just in time for Surume to save them from an Umibouzo. After reuniting with the ship, Luffy was then startled when he heard the undersea volcano starting to erupt.

The Straw Hats managed to escape the eruption thanks to Surume and Usopp's Pop Greens. Soon, the crew sees Fishman Island. Luffy then begins to wonder what kind of food there is in Fishman Island while drooling. Then a gang of sea monsters led by Hammond appear. Hammond gives the crew two options: join the New Fishman Pirates or die. As the Straw Hats prepare to run using Coup de Burst, Luffy gives Hammond a rejection.

Trouble in the Underwater Paradise
Hammond does not take kindly to Luffy's rejection and prepares to attack the Thousand Sunny. Franky activates Coup de Burst and the ship flies through the bubble surrounding Fishman Island. After they passed through the bubble, they fell into a current and the crew is separated. Luffy then wakes up in Keimi's house where Sanji, Usopp, and Chopper are also there. Keimi introduces them to some of her friends, the Medaka Mermaid Quintuplets. She then takes the four pirates to Mermaid Cove where they meet more mermaids.

As the crew relaxes in Mermaid Cove, Luffy asks Keimi if he can see Jinbe. When Keimi informs him that Jinbe is not on the island, Luffy shows his disappointment as he was looking forward to meeting him. Soon the Medaka Mermaid Quintuplets inform Keimi and the group that a royal gondola is approaching. Luffy, Usopp, and Chopper then hide behind cover while Sanji is being covered by a mermaid. The three brothers of the Neptune House appear, searching for the people who entered Fishman Island illegaly. The mermaids deny seeing any intruders. As the three brothers are leaving, Sanji gets another massive nosebleed, making him lose more blood than ever before. While Sanji is in critical condition, Luffy, Chopper, and Usopp beg for a blood donation. Hammond and his group then appear and tell the story of how Fisher Tiger supposedly died. After a gruesome battle, Fisher Tiger suffered a critical blood lost and could have been saved with a blood transfusion, but humans refused to help him. Hammond goes on to say that because of the humans who left Fisher Tiger to die, there is a law that prevents fishman and merfolk from sharing blood with humans. Hammond then attempts to capture the four Straw Hats, firing a net at them, but Luffy is able to dodge the net by sidestepping it, and knock out the pirates with Jet Pistol. A sea monster tries to attack Luffy, but he subdues it with Haki. Keimi takes the gondola and helps the four Straw Hats escape and takes them to the town port.

At the town port, Keimi and the four pirates find shelter in Madam Shyarly's Mermaid Cafe. Madam Shyarly provides them a room where they can treat Sanji. Luffy and the others luckily come across Splash and Splatter, a pair of okamas who happily agree to donate blood to Sanji. As Sanji is recovering, Luffy recalls that he got a scar on his arm after he attacked Hammond and his two companions. Luffy noticed that the octopus merman managed to block his attack. Chopper checks Luffy's blood and sees that Luffy was poisoned and is amazed that Luffy's body is able to fight against it. Luffy then remembers an old foe, Magellan. As Sanji is resting with Chopper watching over him, Luffy, Usopp, and Keimi go to the Mermaid Cafe and meet Madam Shyarly, the owner. Luffy and Usopp marvel at Shyarly's crystal ball and learn that Shyarly was a fortuneteller. Luffy asks if mermaids can poop but gets quickly terrified of Madam Shyarly. Keimi then takes Luffy and Usopp to the front entrance of the Mermaid Cafe. Luffy shows his great disappointment when he learns that Mermaid Cafe does not serve meat. The group soon meets Brook and Pappug and they have a happy reunion. Pappug delighted Luffy by offering him sea monster meat and Luffy is glad that there is meat on Fishman Island. The group then travel by riding on a fish taxi and Luffy sees a variety of fishmen and merfolk. They soon come across a candy factory with Big Mom's jolly roger on it. After learning that Big Mom is the new protector of Fishman Island, Luffy comments that she must be a nice person and wonders if he will meet her someday. After passing the factory, they arrive at Pappug's house.

Luffy and the group soon learn that there is a Criminal clothing store on the first floor. As soon as they enter the store, they find Nami making complaints for the high prices. Pappug says that the Straw Hats can have whatever they want for free. After hearing this joyful news, they empty the store much to Pappug's dismay. They then hear a commotion outside the store and they find that King Neptune has arrived to meet them. Luffy and the others are then invited by the King himself to his castle.

Luffy and his group take a ride on Megalo while Neptune rides on Hoe. On their way to the palace, Luffy spends his time sightseeing. Once they arrive at Ryugu Palace, Luffy marvels at the sight of it. After entering the caste, Luffy wanders away from the group in search of food. Luffy had followed his nose but lost the scent. He saw a door that he thought the smell of the food originated from. The double door in question is huge, made of mostly metal, had two sets of handles, ring knockers high above and then regular handles near ground level. Embedded in the doors, were three swords and a double-bladed axe. Embedded in the wall around the doorway was an axe, another sword, and the head of a morning star. Luffy, completely ignoring the weapons embedded in the doors and walls, thought the sturdy look of the walls reminded him of Impel Down. He wondered how good food behind that sturdy of a door could be. When he went through the door, it was pitch black, but Luffy saw food on the other side of the room, making him wonder if the room was the banquet hall. He then wondered if he had found the food vault. Luffy then decided he would only take a little bit of the food, as his stomach was at its limit. While running across the room, he crashed into something. He thought it was coral that felt really soft. When he first touched the coral, he heard a grunt, but thought it was someone outside. He then began jumping on the coral, comparing its consistency to pudding. He then hears someone ask if someone was in the room. A light suddenly came on and Luffy suddenly began to fall.



He falls next to a gargantuan giant smelt-whiting mermaid, the mermaid princess, Shirahoshi. What he had thought was coral was actually the coarse material of her top and the softness he felt was actually her breast. She asked him what he was doing on someone else's body and who he was. Luffy was amazed by the size of the princess. She then asked him if he were here to take her life too, and that she was not scared. She tried to hide her fear by saying she was the daughter of Neptune, but she could not hold back her tears, which were so big that Luffy had to actually dodge the falling water droplets. She then yelled for her father and brothers, as Luffy pointed out that he wasn't doing anything to her.

As she continues crying, an axe thrown by Vander Decken IX comes flying into her room aiming for the princess. Luffy deflects the axe, saving Shirahoshi's life. When the guards come to Shirahoshi's room, the princess hides Luffy from them. She tells the guards that the noise they heard coming from her room was her having a bad dream. The Minister of the Right explains the situation with the Straw Hats. Once the guards leave, Shirahoshi speaks with Luffy. While Luffy is eating, Shirahoshi asks him many questions about the outside world and wonders how Luffy can eat so much while poking him in the cheek. Luffy snaps back and Shirahoshi starts to cry saying that no one had ever yelled at her before. Luffy points out that Shirahoshi is a big crybaby causing her to cry even more. Luffy then offers to take a walk with her outside the castle with him being the bodyguard.

Luffy asks Shirahoshi about where she wants to go. The princess says that she wants to go to the Sea Forest. When she starts crying again, Luffy starts to refer to her as "weakling." Knowing that Shirahoshi's size will draw attention, Luffy comes up with a plan. As Brook and the Minister of the Right arrive to her room, Shirahoshi exits the room stuffed inside Megalo while Luffy rides on top of the shark. Once they leave the palace, Shirahoshi tells Luffy that in the Sea Forest, there is a grave that she wants to visit. Unbeknown to Luffy, Jinbe is there waiting for him. While hovering above Coral Hill, Luffy sees Chopper, Sanji, and a bandaged Hatchan. Once Luffy jumps down to meet them, he is met with accusations from the Fishman Island citizens for mermaid kidnappings. Megalo has finally reached his limit and spits out Shirahoshi. The Fishman Island citizens instantly concludes that this is a Mermaid Princess kidnapping.



After tying up Luffy, Chopper, Sanji, and Hatchan, the citizens discuss about what they should do with Luffy and his group. Once they decide that beheading them is the best course of action, Vander Decken IX flies in on his thrown piece of coral, demanding the princess to marry him. Shirahoshi refuses, saying that Decken is not her type. Enraged, Decken prepares to kill her. The citizens urge her to run, but Luffy tells her to stay where she is because he will not be able to defend her if she gets too far away. Luffy uses Haki to subdue the fishmen restraining him and using only his legs to smash the coral and pummel Decken into the ground. Shirahoshi then unties Luffy much to the surprise of the citizens. The princess, Luffy, and his friends then hop on Megalo as they attempt to flee the scene. Decken calls out to Wadatsumi to intercept them, but Luffy hits him in the mouth with a Jet pistol, shattering one of his teeth. The group then continue their path to the Sea Forest.

They soon reach the Sea Forest and meet Jinbe, Franky, and Den. Luffy introduces Shirahoshi to Franky and is overjoyed to see Jinbe again. Franky then introduces Den to Luffy. After deflecting an axe thrown by Decken, Luffy watches Shirahoshi pays her respects to her deceased mother. Nami and Keimi arrive bearing terrible news about the Ryugu Palace. Jinbe then decides to reveal that he was responsible for allowing Arlong to run wild in the East Blue.

Before Jinbe begins his explanation, Luffy displays his forgetfulness by not recalling what Yosuku said about Jinbe back in the East Blue as well as forgetting the name, Fisher Tiger. In the meantime, Luffy listens to Hatchan as he explains the fishmen and merfolk's dark history and to Jinbe as he explains the ideals of Queen Otohime and Fisher Tiger. Luffy sleeps through the whole thing, only remembering the very beginning when Otohime confronted the robber. After Jinbe finishes his story, Sanji wakes Luffy up by kicking him. A visual Den Den Mushi appears and the group watches Hody Jones' speech.

After Hody Jones explains his plans of creating the new Ryugu Kingdom, he leaves a message for the Straw Hats. After he executes Neptune, he is going to drown Zoro, Usopp, and Brook. He then shows Luffy's wanted poster and says that he will make a fine example out of a 400,000,000 bounty head. Luffy celebrates his bounty increase to while Nami scolds him for it. He then decides that if Hody wants a fight, he has no other choice but to give it to him. However, Jinbe tells him not to go, as fighting Hody will add to the human/fishman prejudice. Luffy, however, tells him that he has to save his crew mates and that if Jinbe wants to stop him, he will have to fight him.

Luffy remains insistent on going to Ryugu Palace. He tries to hop on Megalo, but Jinbe stops him with fishman karate. Luffy counterattacks with a Jet Stamp and Jinbe blocks it. The two then charge at each other when a clone of Robin suddenly appears between them. Before they collide, the clone vanishes and Luffy and Jinbe hit each other. After the real Robin appears, Jinbe once again tries to reason with Luffy, but the Straw Hat captain remains stubborn. Jinbe comes up with a plan that will make Luffy look a hero instead of a villain. Luffy disagrees at first but goes along with the plan when Jinbe agrees to give him all the meat he wants.

Battle for Fishman Island


Luffy goes to Gyoncorde Plaza while hiding inside Megalo. He jumps out of Megalo's mouth at the moment when Hody is about to kill Neptune and attacks the coup leader, sending him flying back. After Jinbe shouts for the rest of the crew, Nami manages to steal back the world nobles' letter, as well as the keys to the royal families' locks, which Robin uses to free them. Above the plaza are the Thousand Sunny and Neptune's whale, Hoe. The Sunny blasts the New Fishman Pirates with the Gaon Cannon while the whale rescues his master and the princes. The island residents ask Luffy if he's a friend or foe, to which he responds that it's their call to make. The rest of the crew then gather at the plaza, and are prepared to engage Hody's crew in combat alongside Jinbe. Upon hearing that Hody ultimately plans to become the Pirate King, Luffy becomes enraged. When Hody orders his subordinates to attack the Straw Hats, Luffy unleashes a burst of Haoshoku Haki and knocks out half of them in an instant. He then tells Hody that no matter what kind of king he plans to become, there can only be one Pirate King. Luffy activates Gear Third and take out more of Hody's men.

As the battle with the New Fishman Pirates commences, Luffy takes the time to gaze and admire Franky's new weapons from the Soldier Dock System: the Black Rhino and the Brachio Tank. When Hody commands Surume to attack, Luffy reminds the kraken that they are friends. Luffy then hops on Surume's back as the beast attacks the New Fishman Pirates. When Hody threatens to kill Surume's family at the North Pole for disobeying him, Luffy understands why Surume had to join with him. He then tells the kraken that he will protect his brothers too. He then walks over to Hody, enraged at the fishman's threats toward Surume. He dodges the attacking pirates, and gives the fishman a swift and devestating kick to the fishman's jaw.

Hody then retaliates by punching Luffy's face, but due to Luffy's rubber body (and Hody's amateur Fishman Karate), Luffy's neck stretches back. Luffy takes advantage of the situation and uses his Busoshouku Haki to harden his forehead. When the Iron Shell Division comes to guard Hody, Luffy uses his head to smash right through them. He then uses his Haki again to harden his arm and block a kick from Hody and then hardens his leg to give Hody a powerful kick of his own. Hody attacks with a Yabusame barrage but Luffy uses his Kenbunshoku Haki to dodge it before giving Hody a Haki-imbued punch that sent him flying. Luffy noted that Hody was tough when he managed to get back up. Upon seeing Shirahoshi willing to sacrifice herself so that Noah would not destroy the island (and Hody climbing up underneath Noah to go after Vander Decken IX), Luffy told his crew that he is going up there. Upon receiving a bubble-making coral from Jinbe, Luffy grabs onto Sanji's leg and prepared to be catapulted up to Noah.

After Sanji sends Luffy flying, he lands on one of the chains. Luffy equips himself with a flutter kick coating before he goes into the sea. Hody attempts to attack Luffy, but he is helped by Fukaboshi. Luffy tells Fukaboshi to take him to the deck of Noah, but Hody goes ahead of them. After Hody deals a devastating blow to Decken, he tries to kill Shirahoshi. Luffy grabs Hody and throws him away.

Hody is undeterred and is still confident that Fishman Island will be destroyed and that Luffy cannot do anything to stop it. However, Luffy is confident in his own abilities after his two-year training. When Shirahoshi changes her course, Hody attempts to stop her, but is grabbed by Luffy again. Unfortunately, Decken passes out and the ship no longer follows Shirahoshi and begins to fall.

Luffy then plans on destroying Noah, but Fukaboshi tells him that the ship is too important to destroy and that they should move it instead. As Luffy and the princes fight against Hody, he keeps interfering with their attempts to stop Noah. Luffy punches Hody into the ship and Hody slices a hole in the air bubble in retaliation, preventing Luffy from boarding it. After Fukaboshi learns Hody's true character, Hody then tries to stop Luffy and Shirahoshi again, but Luffy breaks his Kirisame and sends Hody flying back, and Hody once again gets back up. Fukaboshi tells Luffy about how the New Fishman Pirates were formed out of hatred and resentment. As the prince laments on how everything has been happening, he asks Luffy to bring Fishman Island back to zero. Luffy tells Fukaboshi that he will not let anyone hurt Fishman Island because they are friends. Hody once again charged at Luffy, but Luffy managed to deliver a very devastating blow to Hody's chest.



After the attack, Hody was sent flying towards Noah and crashed there. After getting up and seeing Luffy coming towards him, he eats more pills and prepares to attack Luffy. He uses a new attack called 'Murasame', but he fails as Luffy dodges his attack. Luffy then counterattacks using 'Elephant Gun' and finally defeats Hody Jones. After Hody has been dealt with, Luffy starts destroying Noah. As he barrages the ship with his attacks, the wound he received from Hody starts opening up much to Shirahoshi's horror.

Luffy wrecks the ship piece by piece until Shirahoshi suddenly yells at Luffy to stop. Luffy then sees that the ship has been stopped by the Sea Kings. With the Sea Kings' help, Luffy no longer needs to destroy Noah. As Luffy faints from his wound, he is glad that everyone is safe.

Luffy loses alot of blood from the battle. Shirahoshi carries Luffy back to the plaza. Chopper requests a blood donor, but the citizens are relunctant to help. Jinbe volunteers to be Luffy's donor. During the transfusion, Luffy regains consciousness and asks Jinbe to join his crew.

The After Battle Party, Huge News, and Departure
Not wanting to be thanked as heroes, Luffy and the others quickly leave the plaza. Jinbe declines Luffy's offer of joining the Straw Hats. Jinbe states that while he's grateful for the offer, he states that he has unfinished business to attend to but once that is all done and if he still wants him to join, Jinbe will gladly join and Luffy agrees. One of Neptune's guards catches up with the crew and through a Den Den Mushi, Neptune invites the crew to a banquet. Luffy gladly accepts and went to get Hachi and Keimi first. They all arrive at the palace and have a huge party in honor of their victory.

After partying for a while, Jinbe talks to Luffy and his present crew members about some important information. Jinbe brings them up to speed about what happened during the two years they were all away. He informs them about a dispute between Aokiji and Akainu over the position of fleet admiral. Akainu won the position and Aokiji stepped down rather then serving under Akainu. Jinbe then explains about the Blackbeard Pirates' rise to power with Blackbeard becoming a Yonko. He also warns them that the Blackbeard Pirates are stealing the abilities of powerful devil fruit users for themsleves, but Luffy ignores him and states that he works better without making plans. Luffy then senses something wrong and goes to check on Shirahoshi with Zoro and Sanji and finds Caribou trying to abduct her. Luffy saves Shirahoshi by sending Caribou flying out of the palace. When Nami finds out that Caribou has treasures in him, she sends Luffy, Zoro, and Sanji to capture him and get the treasures for her.

The trio then find an unconscious Caribou and collect all the stolen treasures. On their way back to the palace, they spot a crowd in front of the Candy Factory. Luffy then casually tells Big Mom’s messengers that he ate all the candy. One of the messengers, Bocoms, then wonders what candy Luffy is talking about. However, his crewmate, Baron Tamago, interferes, asking if Luffy really ate the candy. Luffy says that he did and Tamago explains that Fishman Island is under the protection of Big Mom and the island will be destroyed if the monthly offering of candies will not be done. The Den Den Mushi rings, and Bocoms says that it is Big Mom calling. Luffy picks it up and shouts, telling her that he's going to be the Pirate King and that he ate all the candies of Fishman Island. Big Mom does not believe him at first, saying that he's only covering up for Fishman Island. Luffy strongly insists that he did and offers treasures to the Yonko. Tamago then suggests Big Mom to accept the money, because of the fact that the Kidd Pirates sank two of their ships. Big Mom shouts at him, saying that she has decided to target Luffy in place of Fishman Island. Luffy challenges her saying that he will defeat her and make Fishman Island his territory.

Even though Luffy infuriates Big Mom, he still hands over the treasures to Tamago and Pekoms. The Monster Trio then return to Ryugu Palace and explains the situation to everyone there. The three then recieve a beating from Nami for giving away the treasures.



Later when the Straw Hats are departing Fishman Island, Shirahoshi tearfully wishes for Luffy to stay longer, which causes Luffy to scold her for crying so much and she appologizes. As the Straw Hats leave, Shirahoshi swears to Luffy that she will stop being a crybaby. Luffy then makes a pinky promise with her that if they meet again, he will take her to the surface. After sailing away from the island, Luffy looks forward to seeing Shanks again.

As they travel to the New World, the crew decides to catch some sea monsters to eat. As they try to catch some, they get caught in a White Storm and are sucked in but stopped by a group of whales that resemble Laboon. After Brook sings Bink's Sake to pleasure them, they help take them to the New World's surface and Luffy says the weather is perfect after everyone else commented on the weather.

One Piece Film Z


Luffy and the Straw Hat Pirates are having a cherry blossom party. Luffy is goofing off, stuffing himself with meat while Brook is singing. Chopper becomes distressed when inhaling poison drifting in the air, while Brook is inspired to write a song about it. The smell is shown coming from Usopp spraying poison over his Pop Greens, as Robin happily waters some of the plants. Usopp reassures Luffy that the poison is merely meant for killing worms with Zoro showing a liking to the tainted flavor of his alcohol.

Chopper finds his milk still tastes bad and worries it's because he's growing up into an adult. Luffy tries it and finds it tasted horrible too. Volcanic ash begins to rain from the sky, with Chopper pouting it's ruining his fur. Nami studies her log pose and finds the needle spinning where the volcano had erupted from. Usopp whispers to her that they have to hide this from Luffy, and choose a safer route. Luffy notices it anyway, deciding to head in that direction.

Luffy spots the battered body of Z clinging to life on a piece of wood out at sea, and tries to rescue him. When he grabs ahold of his mechanical arm he becomes weak with Sanji and Usopp having to help pull him aboard. Chopper examines him, but finds that he should be fine. Robin notices his arm is built out of Kairoseki, the reason why Luffy became weak when he touched him. Nami finds it a dangerous thing, but Luffy and the others are in awe over it. Sanji reminds them all that Kairoseki is used against Devil Fruit users with him and Zoro debating whether to throw him overboard. Chopper defends him, with Luffy ordering him to save his life and that he'd deal with him if he was an enemy.



Z meets Luffy and immediately tags him as the ships captain. Luffy asks him what he plans to do next, as Z tells him he is carrying a Vivre Card and his comrades should find him soon. Luffy begins asking questions about his mechanical arm, asking where he bought it. He tells them how when he lost his arm to a pirate, a Marine scientist helped build it for him. He tells Luffy its use against Devil Fruit users, able to weaken any foe once he gets a grip on them.

He does comment that due to its heavy weight, it would be hard to survive if he fell into the ocean and only a special key can take it off him. Luffy asks if he is a Marine, to which he responds he had left them for being too old and is pursuing a different goal. Luffy comments it would be bad if he was a Marine, telling him they are pirates.



Z is angered by this, and throws Luffy through the wall. He asks Luffy why he is a pirate, as Luffy proudly responds he will be the Pirate King. This comment infuriates him, as he madly swings his Battle Smasher around. Luffy, Zoro, and Sanji all begin fighting him with Z able to hold them all off with relative ease. Ain and Binz then arrive with a fleet of ships and board the Sunny, announcing they will be confiscating it.

Z overpowers the Monster Trio, as he holds Luffy in his grip, helpless against him. He chastises Luffy's dream, telling him he'll never be Pirate King with his strength. Curiosity piqued, he asks Luffy his name. When he tells him, Z connects him as Garp's grandson and spares his life. He announces to the Straw Hats he will destroy all pirates, as the Neo Marines begin to attack the Sunny. With the ship being damaged and most of the crew unable to fight back, Luffy has them retreat. He frees Franky from his bonds, as he uses a Coup de Burst to escape.

Luffy and the Straw Hats are recovering on a nearby island, where Franky goes to work on fixing the Sunny. He tells Luffy to go after Z while he repairs the damage done. Chopper regrets saving Z's life, but Sanji tells him a pirate should live without regrets of what he believes in. Nami tells him that they must track them down, or else she will never get her original body back. She wouldn't be as helpful a Navigator to them without her full grown body. Nami proposes gathering intel on their enemy as the first place to start.



Mobston, an old man approaches them and asks if they had a run in with Z. He tells them many pirate ships that have come to the island have been attacked by him. He tells that many who had been attacked by him, lost their will to continue and left the New World. He is pleasantly surprised Luffy still wishes to fight him, after losing so badly to him and offers up his finest equipment to use in their quest. Nami tells the crew to not arouse suspicion, they need a new change of clothes first. They are told their best place to start is to take the Sea Train to Secon Island.

As they head to their next destination, they split up their search. Luffy, Brook, Sanji, and Zoro, all relax in a local hot spring to rest, recover, and prepare for the upcoming fight. Sanji comments Devil Fruit users are a pain, seeing Luffy and Brook become quite weak. Sanji tells Luffy to keep a low profile since the island is crawling with Marine soldiers.



As Luffy and the others relax in the hot springs, Luffy vows to not let his guard down around Z again. Sanji tells him as long as he is a Devil Fruit user and lets himself get caught by his arm he will lose, offering him and Zoro to fight him instead. Luffy turns him down, knowing to avoid his arm for their next fight. Among the other people in the bath is Kuzan who was eavesdropping in on their conversation. He chimes in saying he was getting tired waiting for them, leaving them to all immediately panic.

Kuzan reassures them he is not there to capture them, and had given up being an Admiral. He tells them again he is not their enemy anymore and reminds them if he was he wouldn't be in a hot spring where he can't use his powers. As Kuzan gets out of the water, the Straw Hats see his battle scarred body, and his missing leg that he regrows with his ice powers. He merely says he got carried away, when explaining this.

Kuzan and the Straw Hats talk some more, with Luffy asking him what happened to his leg. Kuzan takes offense and tells him there are some things that shouldn't be asked. Luffy tries to change the subject and asks about Akainu on why the two of them fought, believing they were friends. Kuzan refuses to comment on that. He does go on say that he wishes his only reason for coming was to enjoy the hot springs, but is chasing Z. He guessed that they had gone against him, remarking how strong he is.



Afterwards, Kuzan and the Straw Hats are seen making their way to port. He tells them that Z plans to destroy piracy by destroying the One Piece. He has chosen to follow Z's journey, but is unsure what actions he himself must take. He then departs, telling Luffy he will find Z on the island.

Luffy thinks back to his encounter of Z pondering over him, until the rest of the Straw Hats catch up with them with a group of Marines chasing them. Luffy dispatches them all with his Haoshoku Haki. Reluctantly, the Marine Captain tells him the location of Z. The Dyna Stones on the island explode, causing the volcano to erupt. Z informs his men the destruction the Second Point has been a success and they need only destroy one more island.



Luffy charges forth and attacks with his Gum Gum Rifle technique. Z blocks it, showing mild surprise to see Luffy. Luffy demands Z change his friends back to normal, as Ain and Binz attack. Sanji and Zoro intercept them, fiercly battling them both. Z tells Luffy if he wants something, he has to take it like a pirate. Luffy and Z both strike, the shock setting off the volcano to explode forth with magma. Kuzan saves the lives of some civilians by knocking away a volcanic rock and tells them to get to the Sea Train. Kuzan looks on at the devasation, wondering if Z has finally lost his mind.

Luffy tells Z he won't be able to catch him this time, entering Second Gear. Z sends a volley of bullets at Luffy that he dodges before attempting once again to land a hit. Z blocks him again, but this time using the power of his Armament Haki on his normal arm. He asks Luffy to become Pirate King if he has the determination to risk his life, and his friends. He knocks Luffy back, sending him running with more shots from his arm cannon. Growing more angry, he asks Luffy if he is willing to walk over his friend's corpses to achieve his dream before sending out a powerful blast.



Luffy and Z clash furious blows, with Z mocking Luffy telling him if he keeps being afraid of his Battle Smasher, he'll never land any hits on him. He strikes the ground, sending Luffy flying aways. He catches up and fires more bullets at Luffy that he deflects back at him. Luffy tells him his bullets will never harm him, until Z pulls out a small pistol and fires a bullet into his shoulder made from Kairoseki. Mocking Luffy further, he tells him the strongest people in the New World would have never have let themselves be hit with it and he relies too much on is Devil Fruit power. He takes Luffy's hat, promising to bury it himself once he has finished destroying the age of pirates.

Luffy tries to grab it from him, telling Z the hat was given to him by Shanks. He grabs Luffy in his powerful grips and tells him Shanks, along with the rest of the Yonko will all die before they know what is happening. Luffy is enraged, screaming at him to not mock Shanks as Z blasts Luffy away. Zoro and the others find Luffy, and help carry him to safety as the deadly ash cloud rolls down the mountain.

Usopp uses one of his Pop Greens to make a banana shaped boat they ride against the wind with. They are unable to escape and just as their deaths seemed imminent, Kuzan encases the magma and ash in a gigantic layer of ice giving them time to escape. Luffy and the Straw Hats board the sea train and flee, just before the island blows.

The Straw Hats return to Dock Island, as Luffy is patched up and has the Kairoseki bullet removed. Kuzan appears before the crew again, telling Luffy to stop moping. Robin is shown terrified, but Luffy assures her it's alright. Kuzan tells them how Z was a former Admiral, and how he stole the Dyna Stones. He goes on to tell him his plan is to destroy the three Endpoints with the Dyna Stones to release the Grande Imbuto, killing all pirates and destroying the One Piece.

Now that two of the Endpoints have been destroyed, Z is about to go to the last one, Piriodo, and unless the Straw Hats stop him, the Pirate Era will end. The Endpoints had been considered a legend, with most thinking it was nonsense. The government covered up the truth about them, to dissuade pirates from using it. That only the World Government and highest ranking officers of the Marines know about it. He laments that it is an Admiral abusing this knowledge above all else. He reminds them that he is not doing this out of power, but to punish pirates.



Luffy remains undeterred despite being defeated twice by Z, vowing to chase him down and get his hat back. If he lets Z keep his hat, he could never face Shanks or be worthy of the Pirate King title. Kuzan then gives the crew an Eternal Pose leading to Piriodo. If they lose to Z, they will be destroyed along with the New World. Or, if they win they will be attacked by the Marines. With that said he leaves them to their own fates.

Luffy and the others suit up in new battle uniforms, brandishing two swords and a large stick of meat on his back. As they are leaving, Gari approaches Luffy telling him he wants to grow up to be a hero but cant decide whether he wants to be an Admiral or a pirate. Luffy flatly states pirates aren't heroes. Sanji chimes in saying if both feel the same, then it's okay. Gari watches the Straw Hat Pirates leave, filled with admiration for him.



The Straw Hats intercept a blockade of Neo Marine warships guarding Piriodo. They blast through their defenses with the ship's main cannon. They land on the beaches with an army waiting for them. The Straw Hats begin fighting, using their new weapons to help. Luffy tries fighting with two sabers, but he quickly discards them shouting for Z to appear. Luffy finishes fighting off a large group of Neo Marines, as he had used his large meat stick as a club. Feeling tired, he eats the emergency food gaining his stamina back for the fight ahead.

Meanwhile, Z himself is sitting in the mouth of the volcano surrounded by Dyna Stones placed to blow. After a swig of his wine, he stares eagerly at Luffy's straw hat awaiting his inevitable arrival. Luffy is shown fighting off more Neo Marines, trying to stop his advances. He uses his Haki, dodging multiple shots from cannons gradually getting closer.



Luffy finally finds Z waiting for him inside the volcano. He discards his jacket, as the two engage in a furious battle. Luffy pounds away against his Battle Smasher arm, with Z calling his efforts useless. Their fight grows more intense, Luffy's shirt incinerating off him from Z's raw strength. He tells Luffy he cannot defeat his justice. Luffy unleashes his Gatling Gun punches, able to land a few brief hits on Z's body but he shows no sign of any harm.

He compliments Luffy on having courage for a pirate, remarking he is far braver than the Marine. Luffy inflates his fist to Gear Third, using his Gigant Pistol move at Z. Z matches Luffy's hit with his Smash Blaster, both unable to push each other back. Z begins showing signs of fatigue, as the two rush and smash each others fists against one another as hard as they can. The force of the impact sends rippling shock waves along the volcano.

The Straw Hats catch up to the battle, seeing Luffy had managed to leave an imprint of his fist inside Z's giant metal fist. Z asks him why he wants to fight him so much. That even if he defeats him, nobody will thank him for his efforts for the stigma of being a pirate. Luffy responds if he can't defeat him, he will never be able to become the Pirate King. Z then discards his cracked Smash Blaster, revealing a smaller mechanical arm he can still use. Z tells Luffy he is going to dedicate his life to ending his ambition, challenging him for their final bout.



Z and Luffy activate their Armament Haki, their arms turning a hardened black. The two engage in a brutal fist fight, both striking each other with imbued Haki. Kuzan is seen watching their match from a distance, stating "Black Arm" Zephyr has returned. Z and Luffy both give each other hard punches to the chest and stomach, giving Luffy a moment to recoil and puke. Luffy strikes back a punch that knocks Z's glasses right off.

A brief flashback is seen in his mind of his early childhood, rattling his early memories. Z becomes elated, that he is being given such a good fight. Both Luffy and him are worn out, still pushing each other with punches back and forth. He corners Luffy and begins pounding on him, with Luffy showing little sign he can defend himself anymore. As Z begins to gain the upper hand, Luffy pushes him back with a kick.

Fighting on their last reserves, Luffy shouts he is going to be the Pirate King with Z shouting his name in absolute confidence. After exchanging a few more blows to one another, Luffy finally collapses from exhaustion. Z falls to the ground after, unable to fight anymore too. Z bitterly says he's gotten old, and his body can't keep up with him anymore. He finds it disappointing, telling Luffy he was enjoying fighting him.

As the battle ends, the Straw Hats rush over to Luffy's aid, with Ain and Binz doing the same for Z. Z tells Luffy to finish him, but Luffy merely tells him he's already satisfied, giving him a smile. He offers to continue fighting him, if he wants but Z turns him down, also being satisfied.

Kizaru then arrives with his army, telling them he is going to kill them all. Z says he's done everything he's wanted to do, and now will face the price for it as he marches towards the Marine army. He dismisses Luffy, and tells him to leave the rest to him. Ain tries to rush to his side, but Kuzan summons a giant wall of ice dividing everyone from him. Luffy silently looks on, honoring his sacrifice.

The Straw Hats depart the island, watching the battle unfold in grim silence as Z gives up his life to save them. During the credits, it is revealed that after Z's defeat, the Straw Hats returned to Dock Island one last time, to return the gear and weapons Mobston had given them. They bid them farewell, and Gari decided to become a pirate, wearing Luffy's borrowed attired.

Arriving at Punk Hazard
Soon the crew spots an island surrounded by a sea of flames. Luffy is excited to go there even though it seems dangerous to approach the island. The crew then hears a Den Den Mushi ringing and Luffy answers it ignoring Robin's warnings that it could be a trap set up by the Marines. Luffy then receives a call from someone who seems to be in trouble and supposedly resides on Punk Hazard. Luffy then decides to rescue the mysterious person. After Nami creates a road of clouds, Luffy goes to the island with Zoro, Usopp, and Robin. When they get there, they explore and find a massive skull that they determine to be larger than a giant's. Suddenly, they encounter a beast believed to be legend: a massive dragon. As Luffy and his companions are surprised, the dragon supposedly asks who they are.

The group engages the dragon in battle. While fighting the dragon, Luffy discovers a pair of legs attached on top of it which is the source of the talking. Eventually, with a combined effort from Usopp and Luffy, Zoro manages to cleave off the dragon's head. Luffy then pulls the pair of legs off the dragon's head and the group is shocked that it does not have an upper body. The pair of legs then takes off in pursuit of a Shichibukai while Luffy excitedly asks the legs to join his crew.

After the group cuts up and eats the dragon meat and takes the rest with them, they continue their expedition. Luffy decides to play with the legs, placing them on his back and pretending to be a centaur, even though the legs keep flipping him over. Zoro then draws the group's attention to a remarkable sight: a lake separating the flaming half of the island from a frozen, mountainous region on the other half. Usopp then sights a humanoid figure with wings.

While Zoro, Usopp, and Robin receives a call from Brook, Luffy meets a centaur. Luffy then fights and defeats the centaur. A second centaur appears and attacks Luffy, but Robin subdues it. Luffy also nicknames the legs "Leggy". The group then decides to go to the frozen side of the island.



To cross the lake, Usopp forms a boat from Pop Greens. As Luffy's group rides on the boat, the centaur that Luffy had just fought jumps after them and informs his boss that the pirates are heading his way. The four Straw Hats then see a group of centaurs waiting for them on the other side. The centaurs then fire their bazookas at the water around the boat, capsizing it and leaving Usopp and Zoro keep Luffy and Robin afloat. Zoro moves to attack the centaurs, but is instead dragged underwater by sharks. The centaurs prepare to attack the Straw Hats again, but they are stopped by Brook, giving Luffy, Zoro, Robin, and Usopp enough time to escape the lake. After emerging from the freezing water, the four Straw Hats plan on stealing coats from the centaurs. After defeating them and stealing their coats, the group uses Brownbeard as transportation to Vegapunk's former research facility. They soon arrive at the scene where Trafalgar Law and Smoker just fought. Seeing Law, Luffy reacts in surprise and enjoyment. Luffy quickly thanks him for his help two years ago and asks him where "the talking bear" is. Law simply states that they are both pirates, reminding Luffy that they are rivals, and then tells Luffy to head to the backside of the facility. Right after Law goes back into the building, Luffy's group quickly leaves the scene to get away from the marines. The group then meets up with their remaining crew members.

While taking shelter in a laboratory ruin, Luffy is saddened that he has to give back "Leggy" to the Samurai from Wano and is surprised to learn that Law became a Shichibukai. The Straw Hats then tie up Brownbeard and bring each other up to speed on the current situation. After interrogating Brownbeard, they learn about a man known as Caesar Clown. Kin'emon later leaves the group to find his torso and Sanji, Brook, and Zoro go out to find him. Before long, several of the giant children start to feel pain, saying that they need candy usually given to them in order to make the pain go away. However, Chopper states that the candy contains a drug that the children became addicted to and Luffy's group learns that the children have been experimented on. One of the giant children then hits Luffy and the others go on a rampage, forcing Usopp to put them to sleep. Luffy's group decide to help the children and find the man that Brownbeard calls his master. They then tie up the giant children so that they cannot destroy anything else. Luffy, Usopp, Franky, and Robin then leave Chopper and Nami to watch the children while they head to Caesar's lab. While they are gone, Luffy's group hears an explosion coming from the hideout and Luffy detects the presence of two animals. They quickly turn back to help Nami and Chopper. When they return, the Yeti Cool Brothers open fire on Luffy, and then disappear when Luffy tries to attack. It is then revealed that Nami (in Franky's body) has been captured.

Luffy then sees that Brownbeard has been shot by the brothers and Luffy's group realize that Caesar is warped enough to turn on his own loyal subordinates. Luffy and Franky decide to go after the Yeti Cool Brothers to rescue Nami. Franky takes a Rumble Ball from Chopper and immediately uses it, ignoring Chopper's advice on how to use it. Franky transforms into Monster Point and goes on a rampage while chasing after Luffy. Luffy and Franky follow the giant footprints and fall into an ambush by Scotch and Rock. They first try to skewer Luffy with Icicle Pincushion. Luffy easily destroys the trap unharmed with an Haki-enhanced Gomu Gomu no Gatling Gun. Rock then fires some shots at Luffy. Luffy counters with Gomu Gomu no Thank You Fire, deflecting the bullets right back at Rock, dealing some damage to him. Scotch then fires a shot at a mountain top, causing a giant ice shard to start falling towards Luffy and Franky. Rock prepares to attack again, but Franky grabs the shard and knocks out Rock with it. Once Franky tries to attack Luffy again, Luffy knocks him out with Elephant Gun. Scotch then grabs Nami and attempts to make a run for it with Luffy chasing after him. Law arrives and cuts Scotch in half. Scotch tries to retailate against Law only to be knocked out by Law's Counter Shock. As Luffy breaks Nami's chains, Law proposes to Luffy to form an alliance in order to take down one of the Yonko.

Alliance with Law and Confrontation with Caesar Clown
Luffy accepts the offer much to Nami's protests. Luffy, Franky, Nami, and Law then return to the hideout. The rest of the Straw Hats are surprised that Luffy actually formed an alliance with Law. Law returns Franky and Chopper to their bodies while putting Nami in Sanji's body. Chopper scolds Luffy and Franky for causing damage to his body. The Straw Hats and Law then form a plan to capture Caesar while helping the children.



Luffy is later seen flying with Franky and Robin towards Caesar's lab. After crashing through a Marine warship, he prepares with the others to kidnap Caesar Clown. Tashigi (in Smoker's body) then confronts Luffy, but Luffy easily pins her down. Smoker (in Tashigi's body) steps in and fights Luffy himself. After learning that Smoker is not in his own body, Luffy laughs and tells him that they will fight another day. After Franky blasts the doors, Luffy and his group prepare to storm the facility. Before they enter, pieces of poisonous slime start falling from the sky. Caesar then appears outside of the facility and starts explaining about the slime creature, but is interrupted when Luffy grabs onto him.

Luffy and Caesar subsequently engage into battle. Caesar uses Gas Robe on Luffy, and he inhales all of Caesar's poison gas. Luffy then expels the gas through his ears, much to the surprise of Caesar's subordinates. Luffy laughs at Caesar by saying that his poison does not work on him much thanks to an immunity he gained from his battle with Magellan. He attacks Caesar again, and just when he is about to land another blow to Caesar, Caesar attacks Luffy with Gas Tank, and Luffy gets caught in the explosion. After that, Luffy was trapped by Slime and was later dealt with another Gas Tank. Luffy evades the attacks and proceeds to deal a final blow to Caesar, momentarily defeating him. Before Luffy's group can complete their capture of Caesar, Luffy suddenly faints. As Robin and Franky wonder what happened to Luffy, Caesar laughs and says that Luffy underestimated him.

Luffy is then seen lying unconscious alongside Robin, Franky, Smoker, and Tashigi, who were all knocked out by Caesar. He is then locked in the research facility with Robin, Franky, Smoker, Tashigi, and Law. When Vergo reveals himself to be working with Joker, Luffy asks Law who Joker is. Law tells him that Joker is Donquixote Doflamingo.

While Clown is giving out his broadcast to the underworld brokers about his experiment with his chemical mass destruction weapon, Luffy and the other captives are just sitting passively in their cell. After Vergo is seen with Law's heart and inflicts pain on Law by using his heart, Luffy is surprised Law can still survive without his heart.

After Smiley explodes and spreads a poisonous cloud, the prisoners witness the destructive effects of the gas as some of Caesar's subordinates succumb to it. Luffy then sees Sanji, Zoro, Kin'emon, and Brook all running away from the gas cloud. He then yells that they have to run and cannot die but is weakened by the kairoseki stone. Caesar Clown proceeds to move the captives outside of the facility to die.



Luffy then asks how Law plans to escape, watching as the Shichibukai begins his escape plan. Law directs Franky to launch his Franky Fireball at the segregated battleship down below. The wood is set alight and the smoke from the burning wreck then rises up to the cage, allowing them to discreetly take action. Law quickly reveals that he had replaced some of the sea stone handcuffs with regular ones, allowing him to escape easily and goes on to free Luffy and the others. Using Law's Devil Fruit powers, they are then moved into the laboratory where they open the shutters, allowing everyone outside to escape the poison gas. Seeing the remaining members of his crew arrive, Luffy gleefully claims the battle has really begun.

When his crew are confronted by the G-5 Marines, Luffy asks if the fight has started. Law interrupts the marines and tells them of a way off the island, but they will have two hours to escape. When Luffy asks him what will happen, Law replies that he will do something dangerous. When the groups split up, Luffy decides to go after Caesar Clown once again. After Zoro hears about Luffy's earlier defeat at the hands of Caesar, he yells at Luffy, telling him not to be careless and reminds him that they are in the New World. Luffy agrees and proceeds to attack a group of Caesar's subordinates standing in his way. He later defeats Run the Machete with one strike and continues through the hallway to Passage B.



Luffy and Smoker eventually pass through the B building and reach Caesar's location. Before entering the room that Caesar is in, Smoker tells Luffy that Vergo is his enemy. Luffy replies that he will get Caesar. Once they see the scientist, Luffy immediately gives him a punch. Luffy and Caesar fight for a while, and just when Luffy is gaining the upper hand, Monet steps in and interrupts him. She makes a barrier over Caesar, which Luffy breaks with Jet Gatling. Monet lets Caesar escape, and tells Luffy that if anything bad happens to him, Doflamingo will kill her. Luffy then asks "what" Doflamingo is (instead of asking "who" he is). Monet, however, simply locks him in a ten-layered snow hut and begins to weaken him with her powers. Luffy, however, simply blasts through the floor with a Jet Spear and falls into the basement. However, Monet tells him that unless he can fly, there is no way out of the basement.

While exploring the garbage dump inside the basement, Luffy encounters yet another dragon and asks who is it. Surprisingly, the dragon replies back, asking the same question.



The dragon then introduces himself as Momonosuke. However, Luffy thinks it is an eel and is surprised that it can talk. After Momonosuke points out he is not edible, Luffy introduces himself as the man who is going to become the Pirate King. Momonosuke does not believe him and starts telling Luffy about his perception of pirates, but Luffy interrupts him. Momonosuke then explains his back story, which includes him being taken to Punk Hazard, going to the secret room and eating a Devil Fruit which transformed him into a dragon. Luffy tells Momonosuke that he should just turn back into a human, but Momonosuke does not yet know how. Momonosuke then continues his story, where he overheard Caesar telling Monet that the children will die in five years and that he will get new ones then. He then finishes his story by telling Luffy about how he ended up in the garbage dump. Luffy becomes angry after learning how horrible Caesar is and he tells Momonosuke to hold unto him as he plans on climbing the wall to get out and rescue the children. Momonosuke then has an hallucination of Doflamingo's face and flies out of the basement with Luffy hanging onto him.

They later escape the garbage dump through a dust bin. Luffy then confronts three of Caesar Clown's underlings, demanding Caesar's location. The frightened underlings immediately tell him that Caesar is in Building R, straight along the corridor. Luffy then arrives at Building R just in time to save Brownbeard by knocking away Caesar with a Haki-imbued Gear Third attack. As Luffy prepares for a third confrontation, Caesar taunts him, telling Luffy that he will be in danger from both Doflamingo and a Yonko if he attacks him. Luffy then punches Caesar in the face, saying that he has been dealing with people like that since he entered the Grand Line. Caesar then warns Luffy again about the kind of people he is dealing with and attempts to retaliate with a gas-burner attack. Luffy dodges and punches Caesar in the face again.



Caesar then forces his men in the control room to open the air vents, allowing his gasous weapon to flow in. Caesar absorbs his weapon and grows bigger. He then kills more of his subordinates, angering Luffy further. Luffy asks Momonosuke to look after Brownbeard and then runs into a hallway to get some distance away from Caesar. Luffy enters Gear Third and charges at Caesar, angrily shouting that he doesn't want to see his face anymore. He attacks Caesar with Grizzly Magnum, not only sending him through the gate to the escape passage but also sending him flying outside of the lab. With Caesar out of the way, Luffy is then reunited with his crew and the kidnapped children. Luffy meets Law and Smoker again in the corridor between Building R and D. When Luffy tells Law that he sent Caesar flying, Law scolds him for not following the plan of capturing him.

Chopper, Brook, Kin'emon, Mocha, and some of the G-5 Marines still haven't arrived at Building R. Luffy waits patiently for them despite Law's urges to escape as soon as possible. Fortunately, the remaining group arrives safetly before the gate to Building R seals off. Everyone boards the rail car and goes through the escape passage.



While going through the escape passage, Luffy helps defend the cart from the falling rubble. When they finally reach the outside, they find Franky in his Franky Shogun after he was just fighting against Buffalo and Baby 5. As the pair attempt to flee with Caesar, Law prepares to stop them himself, but Usopp and Nami insisted to handle them themselves. Luffy encourages Law to give his crew a chance. After the defeat of Buffalo and Baby 5 and the successful capture of Caesar, Luffy smiles as Law declares the first stage of his plan complete.

Aftermath
During the aftermath, Luffy had a friendly chat with Brownbeard, who decided to turn himself in to the Marines. Luffy was then surprised to see Kin'emon breaking to pieces and then reforming to his normal state. Luffy was also surprised to see Momonosuke return to his human form. Sanji made food for the father and son and Luffy was excited to see such delicious food. He tried to convince Momonosuke to eat, but the boy was hesitant at first. Momonosuke and Kin'emon eventually ate together and everyone gathered, drooling at the food. Law warned Luffy that it can not get out of hand and that they will to leave as soon as possible and Luffy agreed, but moments after, he declares the party started. Luffy enjoys the food with his crew and new friends.

As Tashigi and her men took the children away from Punk Hazard, Luffy left with his crew, Law, Kin'emon, and Momonosuke. They were later seen on a sea slope. After Nami informed him that their next destination was Dressrosa, Luffy told everyone to gather around so he and Law could explain their next plan. Luffy and everyone listened as Law explained about Doflamingo's connection to the underworld and the plan to decimate Kaido's forces. Luffy then asked Kin'emon if he has something to do on Dressrosa. The samurai replied that he has a comrade being held prisoner there.

During the evening, Luffy was having fun fishing while wearing a samurai helmet and watching Zoro and Kin'emon fight each other. The next morning, everyone read the news explaining Doflamingo's resignation from the Shichibukai. They also saw that the paper mentioned Luffy and Law's alliance as well as the alliance between Kid, Hawkins, and Apoo. Law told Luffy to disregard the other pirate alliance and only focus on their plan.

The Next Objective
Law contacted Doflamingo to discuss the next part of the negotiation. Luffy suddenly interrupted the call and angrily asked Doflamingo if he is the boss of Caesar. Doflamingo stated his desire to see Luffy and informed the Straw Hat captain that he has something that he would want to get which Luffy thought it was meat. Luffy was then put into a trance until Usopp snapped him out of it. After Law told Doflamingo that he will bring Caesar to Green Bit, he and the Straw Hat planned on how to destroy the SMILE factory on Dressrosa. Luffy then got more excited to see Dressrosa and the crew have a big meal. While eating, Luffy heard Law and Kin'emon talking about a place called Zo. Luffy then listened to Kin'emon and Momonosuke's story about how they were shipwrecked and drifted to Dressrosa as well as how Momonosuke was separated from his father. After hearing about how Kanjuro helped Kin'emon escape, Luffy excitely declared that they should save him too. The Thousand Sunny soon approached Dressrosa.

After disembarking, the group began their next phase of their operation. Luffy thought about using Momonosuke, in his dragon form, to fly. However, Momonosuke refused to do so. When Luffy asked him if he is afraid of heights, they got into a small fight until Kin'emon broke them up. The group split into three teams and Luffy went into Dressrosa with Zoro, Sanji, Franky, and Kin'emon to destroy the factory and rescue Kanjuro. While exploring, they saw the things that the country is famous for including living toys. After getting disguises, they stopped at a restaurant to get something to eat. There, they found some thugs taking advantage of a blind man while taking away his money in roulette. The man then demonstrated his gravity-like ability when the thugs attacked Luffy for calling their bluff.

As the man left, Luffy asked who he was, only for the man to say it was better for both of them if he didn't know. After one of Zoro's swords is stolen, he chased after the thief with Sanji and Kin'emon in tow. Luffy attempted to follow them for fun, but was stopped by Franky. Instead, they interrogated one of the thugs, who happened to be a subordinate of Doflamingo, for the location of the SMILEs factory. The thug claimed that he didn't know anything about it. He then said that most of Doflamingo's crewmembers were at the colosseum where there was a tournament being held for a big prize. At first, Luffy thought it was meat, thinking back to his conversation with Doflamingo, only for the thug to inform them that the prize was actually Ace's former Devil Fruit.

Corrida Colosseum
Luffy decided to compete for the fruit, not wanting just anyone to eat it. He offered the fruit to Franky, but he declined, not wanting to lose his ability to swim. Even though the initial objectives were to find the factory and Kanjuro, Franky felt Luffy deserved the chance to fight for the fruit. Luffy and Franky later arrived at Corrida Colosseum where they met a one-legged toy soldier called Thunder Soldier. While Franky told Luffy that he could go full out in the tournament, it was best to keep his identity secret. He nearly gave himself away when he almost signed his own name, but thanks to Franky stopping him, he ended up signing in as "Lucy". He was then taken to the waiting room, where he met all the contestants. One of them called Spartan attacked Luffy, thinking he was a weakling. Much to the other contestants' surprise, Luffy easily defeated Spartan.

One of the staff members of the colosseum was about to disqualify Luffy. Luckily, Sai and Boo from the Chinjao Family stepped in and spoke on Luffy's behalf, saying that Spartan was the one who started the fight. After thanking the Chinjao family for saving him from disqualification, Luffy learned that he has been assigned to Block C. Once he was inside the battle preparation room, Luffy got excited seeing all the armor and decided to put some on to make himself look cooler. While learning about the colosseum's weight restriction on protective gear, Luffy was greeted by Cavendish, captain of the Beautiful Pirates. Luffy accidentally told him his own name, but the other contestants thought he was mispronouncing his alias "Lucy". Cavendish then proceed to tell Luffy his backstory such as how he came to resent the Eleven Supernovas, but Luffy ignored him during the middle of the conversation. He then sees a bronze statue of a man named Kyros. While admiring the statue, he met a female gladiator named Rebecca, who told him the story of Kyros. Luffy then sees that Rebecca was determined to win the Mera Mera no Mi to defeat Doflamingo. After Luffy and Rebecca finished their conversation, the winner of Block A was announced and Luffy was shocked to see that it was Jesus Burgess.

Before Block B began, Luffy took a look at the warriors defeated by Burgess. He was then approached by Bellamy, who told him that he also visited Skypiea. Bellamy said that his reason for joining the tournament was a chance to join Doflamingo's crew. He went on saying that he has no grudge against Luffy and that he won't laugh at him again. Luffy then watched Block B with Cavendish. As the fights in Block B went on, Chinjao approached Luffy and asked him about Garp, revealing Luffy's identity to Cavendish in the process.

Luffy kept denying his true identity, but Cavendish drew his sword, preparing to attack Luffy anyway. However, Chinjao made the first move, striking at Luffy with a headbutt. Right after Luffy dodged the attack, Cavendish tried to force Luffy to take off his fake beard. Chinjao then launched another attack, but Cavendish wards off the second headbutt with his sword. Chinjao continuously assaulted both Luffy and Cavendish with his headbutts until Luffy punched him into the ground. When Chinjao became very furious, Boo and Sai came to stop him. While the two managed to calm down Chinjao, Luffy hid himself by hanging from a window sill. Luffy continued to watch the match and witnessed Bartolomeo deflecting Hack's attack, which also damaged Hack's hand as well.

As he continued to watch the battle in the arena, he was wondering how Bartolomeo was able to damage Hack like that. He then witnessed that even Bellamy could not stand up against Bartolomeo's strange power. He then cheered Bellamy on, urging him to give it his all. After that, King Elizabello finally threw his legendary "King Punch" which took out all the remaining gladiators in the arena. Even Luffy said that it was an incredible punch and that he had never seen anything like it. Before the King was declared the winner of B Block's "Battle Royale", Bartolomeo emerged unharmed and revealed that he had eaten the Bari Bari no Mi and had created a barrier to protect himself. He then took out the King and was declared the winner of Block B much to Luffy's surprise.

As an injured Bellamy was moved out of the ring, he and Luffy had another friendly chat and commented on how the other had changed. Meanwhile, Bartolomeo overheard Bellamy calling him Straw Hat.



When Block C started, Luffy entered the ring before Cavendish could confront him. When the gong was heard, Luffy was excited to start fighting. As the battle royale went on, Luffy was seen defeating an opponent effortlessly. Some time during the battle royale, Luffy tamed and befriended the Fighting Bull, naming him Ucy. Luffy rode on top of him as he rampaged around the ring. The bull was eventually stopped and crushed by Hajrudin. Luffy then avenged Ucy by eliminating Hajrudin from the competition with a knock-out punch.



Afterwards, Luffy removed Fighting Bull from the fighting area by carrying him over his right shoulder. When he was finished, Luffy entered the fight again only to have his helmet stolen by Jean Ango who heard a rumor that he was Straw Hat Luffy, forcing him to use his cape to hide his identity Jean Ango then threw multiple weapons at him, which Luffy was able to dodge with ease. The weapons aimed at Luffy hit Chinjao instead. Luffy then took back his helmet before Chinjao knocked the bounty hunter out of the ring. Seeing that Chinjao was hell bent on taking his grudge out on him, Luffy decided to fight him head on. Before clashing with Chinjao, he knocked out Sai while Chinjao knocked out Ideo. As the two remaining fighters in the battle royale, Luffy and Chinjao clashed their fists against each other, causing a large wave of Haoshoku Haki to burst throughout the arena

After Luffy declared his goal of becoming the Pirate King, Chinjao asked him who taught him Haki and Luffy answered that it was Rayleigh. Chinjao then bursts into tears, mentioning about a treasure he wasn't able to acquire. Luffy told Chinjao to stick to either crying or getting angry and then continued his clash with him. After taking some punches from Chinjao, Luffy struck back with a powerful attack of his own.



After recovering, Chinjao began mocking Luffy, telling him that those known as the Worst Generation are greenhorns who don't know anything of the world and saying that his attempts to surpass Roger are laughable. He then enrages Luffy by saying executing Ace was a smart move by the Marines. Luffy then proceeds to launch himself in the air with Gomu Gomu no Rocket using Chinjao as leverage. He then activates Gear Third and launches his Gomu Gomu no Thor Elephant Gun while Chinjao takes the attack head on with a headbutt. The two collided, seemingly matched up until Luffy manages to gain the upper hand, which coincidentally restores Chinjao's head to the shape it was before his final battle with Garp. Chinjao is then knocked out and falls down to the arena, splitting it in half with his newly reformed head. Chinjao then falls into the water, unconscious, and Luffy officially wins Block C. Luffy stands victorious as the audience cheers for him.

After Luffy leaves the arena, Cavedish thrusts his sword at him, but he catches the sword effortlessly and holds on to it tightly. Chinjao arrives wanting to thank Luffy for restoring his head but accidentally breaks the floor when trying to bow in respect. Luffy runs away from both Cavendish and Chinjao and is saved by Rebecca. He then ran into Burgess, who was communicating with Blackbeard through Den Den Mushi. Luffy declares that he will not allow Ace's power to fall into Blackbeard's hands. At the Gladiator's quarters, Rebecca bought him some food and sat next to him. Some gladiators behind prison bars caught Luffy and after some hesitation, she tried to kill him with her sword. Luffy dodged the attack and pinned her down. Rebecca asked him why he did not do anything to her even though she tried to kill him. Luffy answered that he won't do anything to someone who bought him food. Rebecca then proceeds to tell him about the convict gladiators and how they were imprisoned in the colosseum for opposing Doflamingo. She says that she wants to win the Mera Mera no Mi in order to be able to protect herself and not have to rely on the Thunder Soldier, who was planning an attack against Doflamingo.

Rebecca then explains to Luffy about how the toys are no different from humans, how her mother died and Thunder Soldier was her guardian after her mother's death, which is why he is so important to her. The conversation is interrupted by Gatz announcing that the ring is repaired and Block D is about to commence. When Rebecca enters the arena, the audience boos and jeers at her. Luffy angrily wonders why and one of the convict gladiators informs him that Rebecca is the previous king's granddaughter.
