King Neptune watches in shock over the sight of the giant ship Noah as Fukaboshi asks whats so important about a relic of the past, but the king replies that the ship must not be damaged no matter what. Luffy and Hody continue their fight with Luffy getting the upper hand with Haki and Hody's attacks being ineffective against Luffy.
Then the ship Noah looms over the plaza and everyone who is fighting in the plaza now notice it. As the ship gets closer, Wadatsumi falls from the ship and onto the plaza. He shouts at Vander Decken decken to stop the ship or he'll die. Vander then shouts out his desire to kill Shirahoshi and everyone in Fishman Island because of her rejection. Hody is seen angry over Vander Decken's betrayal. Shirahoshi is worried that the ship will kill everyone and so decides to use herself as a lure to divert Noah's course away from Fishman Island. Luffy decides to follow her to protect her while Hody grabs on to the giant chains to get revenge on his supposed ally.
The main fight takes to above ground as Luffy launches himself to save Princess Shirahoshi from Van Der Dekken's ship-turned-projectile, the Noah... but he's still got to contend with Hody, and Luffy's still at a disadvantage when he enters the sea water...
Hody Jones takes his trident out of Decken's body and after a short fight, Decken is defeated. After that, Hody goes after Shirahoshi, slicing through Ryuboshi and Manboshi and reaching her with the uncomparable underwater speed, grabbing her hair. Luffy attacks Hody managing to make him release her.
Zeo makes Wadatsumi believe that he has to fight for the New Fishman Pirates in Gyoncorde Plaza. Wadatsumi defeats Surume and then as he attacks Jinbe and gets pushed back, he manages to bring down Nami, which gives Sanji a reason to attack him. Hyouzou becomes stronger after eating too many Energy Steroids. He tries to attack Robin but Zoro jumps in front of him and stops his attack.
Luffy along with the three princes try to protect Shirahoshi against Hody Jones, the captain of the New Fishman Pirates, focused on killing the Mermaid Princess but seems to have an ulterior motive as Vander Decken IX is slowly losing consciousness and his grip on his Devil Fruit powers that keeps the massive ship Noah from falling on top of Fishman Island and its occupants therefore killing them is weakening.
Meanwhile the other Straw Hat Pirates face off against the New Fishman Pirates officers who are equally eager to finish their opponents off as everyone prepares for the fight once again as the fate of the people of Fishman Island rests on Luffy's hands and his crew. As Luffy and the siblings deal with Hody, Decken falls after trying to throw his axe and passes out and the Noah starts falling to Fishman Island.
As the Noah falls onto the Fishman Island, Shirahoshi desperately tries to tell Decken to wake up only for Hody to attack her but Manboshi takes the blunt of the attack. Luffy and Hody clash with Luffy sending Hody to the ship after receiving a bite wound. Hody, knowing that Luffy will have the advantage destroys the bubble on the ship leaving Luffy at his mercy but was saved by Fukaboshi. Fukaboshi then fights Hody himself and despite being heavily wounded in the duel demands to know why Hody is doing all this and what humans did to him. Hody smirks and gave him an answer which shocks Fukaboshi leaving him open and stabbed by Hody.
Shirahoshi following Fukaboshi's orders swims away with Luffy next to the Noah and Luffy receives a call from the Ammo Knights at the air tank saying that they have prepared a large air bubble to surround Noah, but stated that they've only got one shot available and it won't slow the ship down. Hody attacks Luffy again but Luffy destroys his Kirisame and sends Hody flying with his Jet Pistol imbued with Haki . Hody then shovels down more Energy Steroids causing him to grow larger and more enraged. Meanwhile, Fukaboshi, barely alive contacts Luffy and states he has discovered who Hody really is.
The story goes back before the Noah started falling back to the island. Jinbe and Sanji continue to fight Wadatsumi and Wadatsumi becomes angry and inflates himself unknowingly crushing some of his allies. Sanji goads him into growing larger after saying he's smaller than Surume.
At that time, Neptune is greeted by some of his soldiers and the Minister of the Left and appologize for not protecting him. The Minister of the Right arrives at the plaza with some of the army and is informed of the situation and officially join the battle against the New Fishman Pirates allying themselves with the Straw Hats and Jinbe claiming they've made a terrible mistake for blaiming them. Hammond is using human pirates as slaves in his Slave Tank and Jinbe asks Robin to free them and she agrees. She frees them and easily defeats Hammond with her Double Clutch, breaking his back. The freed slaves then revolt against the New Fishman Pirates and ally with the Straw Hat Crew. The Minister of the Left gets in touch with the Air Tank and is informed of the situation and order an evacuation of the island and the citizens all attempt to leave the island.
At that time, the whole island can hear Luffy's talk with the soldiers, Shirahoshi and Fukaboshi stating he knows who Hody Jones really is. He states Hody is a monster born from their environment. He states the officers are all the same and how their just monsters born of hatred born from their ancestors and they fear their hatred will one day fade and so will their hatred towards humans and want them to be evil to justify their actions not even wanting peace for Fishmen. He recalls what he asked what Humans did to Hody and Hody answers "nothing" and that they've been chosen by the heavens to punish humans and granted power. He goes on to state that their hatred is not from beliefs or experience but they're nothing but empty opponents. At that time, Hody laughs maniacally and with blood-shot eyes he charges at Luffy and Shirahoshi.
As Fukaboshi begins to state what Hody really is, Hody's past is revealed as he recalls his hatred towards humans, the New Fishman Pirates officers were taught as kids that the humans are an inferior species and they should be punished by heaven. Time moves forward in time when Hody was a Neptune Army member and he and his crew commit crimes, celebrate the death of Otohime, and start producing Energy Steroids. As the flashback ends, Fukaboshi laments how his mother was killed by the hatred of the island and begs Luffy to bring it back to zero and Luffy says he will since he and his crew and Jinbe all agreed to that and that their friends. Luffy prepares to attack Hody. Franky continues to fight Ikaros Much. Chopper continues to fight Dosun revealing his new Heavy point. Zoro continues to fight Hyouzou and is bored that Hyouzou can't even kill his boredom.
Brook continues to fight Zeo and reveals his new control over his Yomi Yomi no Mi abilities. Usopp continues to fight Daruma and has set traps for him. Luffy attacks Hody with a new move called Red Hawk and it deals Hody an incredible amount of damage and sends him flying to the Noah.
The guards announce Hody's defeat and the lower members try to run away with their captain defeated and Zeo stops them wanting them to die for their grudge. The lower members note how insane the officers are and the children wonder if humans are really that bad and Shyarly states not all are and for them to judge humans with their own eyes. Brook stops Zeo from attacking his men and declares the island will be fine and knows Luffy will save everybody. Franky, Sanji, Jinbe and Zoro prepare to end things with their opponents. Usopp is shocked to see Chopper in his Monster Point only for Chopper to be completely fine.
Hody is not yet defeated and shovels down more Energy Steroids despite his injures and as Luffy arrives on the ship Hody recovers briefly and gives an angry look with Luffy in disbelief as to Hody still fighting.
Hody recovers thanks to the Energy Steroids and manages to overwhelm Luffy and bite him again in the same spot. Luffy retorts with another Red Hawk, but Hody is still standing. Chopper reveals he now only needs one Rumble Ball for his Monster Point. Usopp, Franky, Sanji and Jinbe prepare to end things with their opponents. Luffy attacks Hody with Elephant Gun and Hody is sent crashing into the Noah and is finally defeated and wishes for the Noah to destroy the island and all the Fishman who've lost their pride. Brook finishes Zeo off. Usopp finishes Daruma off. Chopper finishes Dosun off with his claws. Franky blasts Ikaros Much with his laser beam. Jinbe sends Wadatsumi flying and Sanji finishes him off. Hyouzou attempts to attack Zoro from behind only for Zoro to counter and destroy his swords again and defeat him thinking he was a frog. Luffy uses Elephant Gatling on the ship and Hody is blasted out unconscious as Luffy attempts to destroy the ship.
All of the New Fishman Pirates lie down defeated while the Straw Hat Pirates are relaxing and waiting for Luffy. All the citizens of Fishman Island are cheering for him to destroy Noah and thus saving them. While some citizens evacuate the island, some recall how Whitebeard also saved the island at a point in the past and how Luffy reminds them of him. Luffy keeps attacking Noah intent on destroying it while Neptune laments being unable to keep the promise with Joy Boy stating there is no choice but to destroy it. As Luffy continues to destroy the Noah, Shirahoshi jumps in front of him telling him to stop which he eventually does. He realizes that Noah has been brought to a halt by Sea Kings. However, he suddenly faints, falling back down to the Noah. The Sea Kings acknowledge the strength of Luffy's will. After everyone understands that Noah has been stopped, they start celebrating.
With the Sea Kings having stopped and saved the great ship Noah, Shirahoshi learns a startling secret from the Sea Kings. Meanwhile, the missing and captured mermaids have been found but they have been replaced with some other valuable items from the Palace. The remaining humans and New Fishman Pirates are being rounded up and caught by the Strawhat Crew and Jinbe, while Shirahoshi rescues a collapsed and unconsious Luffy from Noah's remains. However, if Luffy is to survive from his injuries taken from his battle with Hody Jones and his unsuccsessful destruction of Noah, the only thing that can save him is a blood transfusion, but the merfolk are reluctant to donate blood as it is forbidden in Fishman Island to give blood to a human. Jinbe volunteers, stating that he is a pirate. The episode ends with Luffy asking Jinbe to join his crew.
As the whole island celebrates the capture and defeat of Hody and his comrades by the Strawhat Crew of whom make their own plans to leave Fishman Island soon while Jinbe reluctantly tells Luffy that he cannot join his crew at the moment but he will in the future when he is finished his won tasks and obligations, They are all soon called to celebrate their victory at the Palace with merriment, music, drink and food.
As the party begins to wind down Robin asks and discusses a troubling and possibly dangerous secret with King Neptune surrounding his daughter, Shirahoshi, the ship Noah and the mysterious Joy Boy.
King Neptune talks about the Ancient Weapons and Shirahoshi with Robin while Caribou listens and makes his way to Shirahoshi's room.
Meanwhile, Luffy regroups with the rest of the crew away from the party after Jinbe insists that he wants to talk to him and explains that Akainu fought against Aokiji for the title of Fleet Admiral on a certain island. Akainu won the title and Aokiji left since he did not want to work under Akainu. He then explains the two changes that happened in the New World after two years: Akainu becoming fleet admiral and Marshall D. Teach taking all of Whitebeard's territories and claiming the title of Yonko alongside Shanks, Charlotte Linlin, and Kaido. Jinbe also tells of a rumour that Blackbeard is searching for the strongest Devil Fruits so he can extract their abilities and claim them for his own use. Luffy does not pay attention to Jinbe's announcements and instead asks Keimi where Shirahoshi is, to which she replies that she is in her room.
Luffy senses a "big animal" in the palace so he calls Zoro and Sanji to come with him and they find Caribou using his Logia powers to capture Shirahoshi. Luffy kicks him out and Minister of the Right thanks him once again. The Minister of the Right wonders why the tower has been cut into pieces and Pappug says that Zoro did it and Zoro gets mad.
Meanwhile in Hody Jones's cell, Hody and his gang appear to be aged by the Energy Steroids and still want revenge against the royal family and humans. The Minister of the Left gets news that Baron Tamago and Pekoms, crew members of the Big Mom Pirates, are on Fishman Island. The Minister of the Left claims that Big Mom will destroy the island if they do not give her candy.
The rest of the Straw Hats are waiting for Luffy, Zoro, and Sanji to return the treasure from Caribou. They find Caribou easily with all the treasure. Luffy, Zoro, and Sanji each take a huge bag of treasure. Meanwhile, Pekoms and Tamago came for the candy but the Minister of the Left claims that there is no more candy and the factory machines have been destroyed by Hody.
Luffy, Zoro, and Sanji find Caribou and the treasure and start to carry the it back, searching for a ride back to Ryugu Palace. On their way back they see a crowd by the sweet factory. Luffy shouts out "Thank you for the sweets, they were delicious!" not knowing that the combats of the Big Mom Pirates, Pekoms and Tamago were there. Luffy gets interested by Pekoms and Tamago's looks and then realize they are part of Big Mom's crew. Luffy had been thinking Big Mom was "a good guy" because she has claimed the Fishman Island as her territory however he realizes that she is only doing it in exchange for 10 tons of sweets.
Big Mom in the New World on Whole Cake Island is waiting for the candy from Fishman Island. Bobbin comes right after Big Mom eats some of her crewmates. Bobbin tells her that he destroyed an island and it smelled sweet when he did. She then learns that Fishman Island will not be giving her candy. She calls Tamago and Pekoms and they dare not answer so Luffy does. Luffy tells her that he ate the rest of the candy and he is willing to give the treasure to her for repayment. Tamago sees the huge amount of treasure they have and thinks it would be a good idea to keep it however, Big Mom refuses and she says that she will go after Luffy in the new world. Luffy claims that he will beat her up in the New World and claim Fishman Island as his own territory.
The Minister of the Right is thanking the Straw Hats for saving Fishman Island. The Minister of the Right gets a report that the Tamate Box is gone and is in the hands of Tamago and Pekoms.

The Minister of the Right tells King Neptune that the Tamate Box is gone and it might explode in the hands of Big Mom. Jinbe decides to cut off the alliance with Big Mom before things get ugly.
Caribou finds Tamago and Pekoms with his treasure that he stole and attacks Pekoms with his gatling gun. Pekoms is revealed to be a Devil Fruit user.

She complains and says that she will tell the crew where to go but Luffy complains saying that he is the captain so he should decide where they should go. Franky gets a new haircut and they start to leave but Shirahoshi comes and ask them to pinky promise to come back and the crew does it.
The Straw Hats finally leave and some of the children of the Fishman Island ask their parents if they can get a Straw Hat similar to Luffy's and Jinbe says he will get some. Luffy then remember the times when Shanks, Rayleigh, Jinbe, and Ace told him something important. The Straw Hats then comment about what they will do once they are in the New World.
Heading into the New World, the Straw Hats (minus Nami and Chopper) are seen constructing something on deck. Inside, Nami is showering while Chopper asks if they'd be okay without her outside. Assuring him everything would be fine while deterring Sanji and Brook from peeking on her, Luffy, Zoro and Usopp set their eyes on catching a deep sea fish to eat. Knocking out the one Luffy had wanted, Usopp fires a makeshift fishing line into the fish's mouth in order to reel it in. Suddenly a two consecutively larger fish attempt to eat their predecessor on the line with the final fish being killed by Zoro who uses an upgraded technique.
Due to the extra weight of the fish, the Thousand Sunny is drawn into a nearby White Strom, where after being tossed around extensively they are then stuck by something massive and are ejected from the current, discovering a pod of Island Whales to whom Luffy and Brook mistake for as Laboon. Despite realizing they weren't his friend, Brook still chooses to play a song for the whales who then help them to the surface of the New World where they're thrown into a rough sea and come across several Marine warships.
The Straw Hats find themselves in a middle of an infamous sea in the New World known for its mirages and outrageous weather patterns. After surviving the night, the Straw Hats began to enjoy a relatively calm but hot day at sea only to find that all their food is mysteriously disappearing from right under their noses. Could the sea be haunted or is there a stow away on board? Either way, Luffy is determined to catch the thief taking his food.
Nami creates a plan for the Straw Hats to rescue Lily's father, Panz Fry. Chopper, Robin, Brook, and Luffy are the diversion group while Usopp, Sanji, Zoro, and Lily are in the submarine. Luffy goes on the submarine because he finds the diversion group boring. They rescue Panz Fry, but Momonga attacks Luffy, forcing Zoro to intercept him.
Shuzo attacks the Marines and Panz Fry. His pet alpaca Alpacacino shoots out a cannon ball at the Marine ships. Shuzo attacks Panz Fry directly but is intercepted by Luffy. Shuzo then kicks Luffy into the sea. Zoro jumps into the water to save his captain, and Shuzo and Sanji get into an argument. Shuzo tells Momomga the reason why he quit the Marines, much to the dismay of the rest of his crew. Luffy and Zoro then resurface and Luffy threatens Shuzo. Luffy and Momonga prepare to fight Shuzo.
Luffy and Zoro face off against Shuzo and Momonga. The Straw Hats, Lily, and her father manage to escape with a Coup de Burst and the anchor connected to the Thousand Sunny. Shuzo defeats Momonga and the Marines before going after the Straw Hats. He prepares to fire his own men as torpedoes at the island the Straw Hats are on.
Shuzo orders his men to be launched at the island like torpedoes and sacrifice themselves for him. He then attacks Panz Fry and Lily. Luffy faces off against Shuzo but starts to be overpowered by Shuzo and Alpacacino. Lily goes inside Luffy and turns into a giant with her ability. Luffy defeats Shuzo and his pet alpaca and the group gets to eat the heavenly food from Panz Fry before setting off for another adventure in the New World.
Meanwhile, Ain is talking with Zephyr, where it is revealed to him that Shuzo lost. Ain takes the blame, but Zephyr does not care since Shuzo will not tell the marines anything. Therefore, they begin their assault on the first island in the New World, which leads to Film Z.
