It has also been prophesied by Madam Shyarly that someone bearing a straw hat will destroy the island.
Though it is literally directly under the main seat of power of the World Government, Fish-Man Island was previously under the protection of Whitebeard and Big Mom, and now the Straw Hat Pirates. It is also notoriously difficult to reach, with only 30% of the ships surviving the journey. Even someone as powerful as Monkey D. Garp found the journey to be very dangerous and tense. The island is encased in a giant bubble, allowing human visitors to breathe. For World Nobles, it is also one of the few places in the world where their ability to summon a Marine Admiral as they please is not so easy to accomplish.
Fish-Man Island is said to be an underwater paradise. Because it is underwater, the only way for a conventional ship to get there is to be coated with a special resin found in the Sabaody Archipelago, and all ships entering the island must undergo a customs inspection. The island is divided up both by class and by species of creature who lives there. Many of the merfolk live in one section of the island, with the fish-men living in a special district and another section for the richest members of sea society, which includes Pappag. Poor and disenfranchised fish-men and merfolk were shunted off into the Fish-Man District to be ignored by the upper classes and preyed upon by human pirates, brigands, and slavers with no protection from the Island’s military.
Class also shows itself in various living facilities, where the richer creatures live on the higher floors, closer to the light from the surface, while the poor ones live in the lower, darker areas. The Mermaid Café is especially popular in the island. Even though there is a distinction between fish-men and merfolk, inter-species marriage between the two is allowed. However, donation of blood between humans and fish-men…
Fish-Man Island is an underwater island which dwells 10,000 meters below sea level in a giant hole that goes under the Red Line at the bottom of a deep trench. The island resides in a giant double-layered bubble floating above the sea floor, seemingly filled with about half water and reef and half air. Ryugu Palace rests in a smaller bubble on top of the main island’s bubble. It is illuminated by the Sunlight Tree Eve. It serves as an underwater gateway to the New World for those who do not wish to cross over the Red Line above.
The entirety of Fish-Man Island is ruled by the Ryugu Kingdom, and as such, every landmark falls in the kingdom.
Fish-Man Island came to be because fish-men on the ocean floor would gather at the only place where sunlight reached them. That place eventually became Fish-Man Island. The sunlight came from the roots of the Sunlight Tree Eve, which would absorb sunlight on the surface, and then send it down to Fish-Man Island via the tree’s roots. During the Void Century, a man from the surface, by the name of Joy Boy, made a promise with the island to use the power of the legendary Mermaid Princess, the ability to summon and control Sea Kings, to accomplish a certain task that involves the great ark, Noah. Joy Boy failed to keep his end of the promise, so he left an apology on a Poneglyph in the Sea Forest, along with his legacy that someone in the future will complete the promise.
Until that day arrives, Noah was guarded by Fish-Man Island, to ensure the promised day would arrive. Also, the Mermaid Princess’ legend would be passed on, with her powers being hoped not to awaken due to the immense potential of worldwide destruction.

Until that day arrives, Noah was guarded by Fish-Man Island, to ensure the promised day would arrive. Also, the Mermaid Princess’ legend would be passed on, with her powers being hoped not to awaken due to the immense potential of worldwide destruction. At some point later, the cursed pirate Vander Decken came to Fish-Man Island to find the Mermaid Princess for himself, only to die when he reached the island, leaving his descendants to continue the search. Seventy years before the current storyline, the heir future to the royal throne, Neptune was born and visited by Elbaph’s King Harald during a celebration. Because it is the only way for any ship to enter the New World, for if people went through Mary Geoise they would have to leave their ship behind, Fish-Man Island was often visited by pirates passing through and the Marines chasing after them.
When the Great Age of Piracy began, this problem escalated to extreme proportions. With this, many fish-men and merfolk were constantly kidnapped and sold off as slaves. However, when Whitebeard became close friends with King Neptune and declared the island as his territory some odd twenty years ago, the problem was solved as attacking the island and its citizens would incur Whitebeard’s wrath. As a result, the island was directly protected, and a stable peace was achieved. Ten years ago, Queen Otohime tried her best to gain support for the migration of Fish-Man Island to the surface world, and made many speeches in hopes of getting petition.
Despite her efforts and popularity, she gained very little support, as the relationship between the species were strained, which only worsened when Fisher Tiger, who liberated many slaves from Mary Geoise, was killed by the Marines, leading to the support Otohime gained to be retracted. Later, the World Noble Mjosgard came to the island to retrieve the fish-men slaves that Tiger freed, but his ship was attacked by Sea Kings, leaving him the sole survivor. The former slaves tried to kill him, but Otohime saved him, and accompanied him back to the surface, retrieving a support from the Nobles to help the island’s immigration. This led to many support from the islanders once again. However, Otohime’s efforts were soured when the petitions were burned and she was assassinated in broad daylight by Hody Jones, which caused an uproar on Fish-Man Island, and Hody was able to frame a human he hired to shake the islanders’ perception on humans. It was also during this time that the Mermaid Princess of the current generation, Shirahoshi, became a target of Vander Decken IX. Decken, obsessively attracted to Shirahoshi, started sending her threatening marriage proposals to force her to marry him. Because of Decken’s ability to hit his targets from anywhere, Shirahoshi had been locked in Hard-Shell Tower for her safety.
During The Timeskip
As Whitebeard died during the war, the island lost its protection, but shortly afterward Big Mom claimed Fish-Man Island, although in contrast to Whitebeard’s protection for benevolent reasons, she provides her protection in exchange for a large tribute of candy every month, thus restoring peace. After parting ways with Luffy, Jinbe attempted to return to the island, but with it no longer protected by Whitebeard and the resignation of his Warlord of the Sea position, he was forced to leave the island once again for his own protection. He left a message for Prince Fukaboshi to deliver to Luffy once he finally arrived on the island.
Fish-man Island Saga
Fish-man Island Arc
When the Straw Hat Pirates arrived at Fish-Man Island, they were blocked from entering the bubble by the New Fish-Man Pirates who were unsure whether they should trust Luffy and would only let them pass if Luffy became an underling. To get past them, the Straw Hats used the last bit of air left in Thousand Sunny’s bubble for a Coup de Burst to shoot them through the bubble surrounding the island. After the Straw Hats successfully passed through the bubble, their ship fell into a current and the crew scattered. Luffy, Usopp, Chopper, and Sanji reunite with Camie at her house. Nami, Franky, and Robin decided to split up to do different things.
Nami went shopping, Franky searched for Tom’s little brother, Den, and Robin went to study history. Zoro was later found by the Neptune Army and was brought to the palace. Neptune wanted to invite all the Straw Hats to the palace for a feast as gratitude for saving the Princess Shirahoshi’s pet shark, Megalo, from the kraken. Zoro started drinking even though Neptune suggested waiting for the other guests. At the Fish-Man District, Hammond reported the arrival of the Straw Hats to the captain of the New Fish-man Pirates, Hody Jones.
Hody then ordered Hammond to bring Luffy to him. After getting reacquainted, Camie took Luffy, Sanji, Usopp, and Chopper to the Mermaid Cove where Sanji met the objects of his dreams: beautiful mermaids. When the three princes of the kingdom arrived to search for the pirates, the four pirates hid themselves to avoid arrest. Unfortunately, Sanji could not control himself and suffered his greatest nosebleed ever, forcing the four Straw Hats to reveal themselves. Usopp, Luffy, and Chopper begged for a blood donation to save Sanji’s life, but Hammond showed up and explained about a law that prevents fish-men and merfolk from sharing blood with humans.
Hammond attempted to capture the four pirates, but Luffy was able to repel him and his companions. Camie stole the princes’ royal gondola and took the four pirates to the town port. Prince Fukaboshi then revealed to the mermaids at the cove that he was going to give Jinbe’s message to the Straw Hats. The mermaids from the cove also discovered a tightly sealed barrel that had floated in with the Straw Hats. Ishilly and two other mermaids opened it out of curiosity.
They then discovered the hard way that the barrel actually contained a person, Caribou, who popped out of the barrel and kidnapped the three mermaids. Satisfied, Caribou decided to capture all the mermaids he could on Fish-Man Island. At the town port, Camie and the pirates took shelter in the back of Madam Shyarly’s Mermaid Cafe. Madam Shyarly provided them a room in which they could treat Sanji. The group luckily came across Splash and Splatter, a pair of human okamas who happily agreed to donate blood to Sanji.
After Sanji woke up, he was horrified to see who his blood donors were. Chopper watched over Sanji as he recovered. After having a friendly conversation with Madam Shyarly, Camie took Luffy and Usopp to the front entrance of the Mermaid Cafe where they reunite with Brook and Pappag. Pappag then invited the group to his mansion in Gyoverly Hills. Meanwhile, Madam Shyarly screamed in the streets in Coral Hill, saying that she foresaw the destruction of Fish-Man Island at the hands of a man in a straw hat.
Pappag, Camie, Luffy, Usopp, and Brook arrived at Pappag’s mansion in Gyoverly Hills. They entered the Criminal clothing store on the first floor where they reunited with Nami. Soon after, King Neptune arrived at the mansion and invited Luffy and his crew to his palace. At Coral Hill, the three princes met with Madam Shyarly and she told them of her prediction. Unaware of Caribou’s presence on the island, the people of Fish-Man Island suspected that the Straw Hats were responsible for the mermaid kidnappings.
Meanwhile, at the Fish-Man District, Hody Jones fought and decimated some of his human captives, Crab-Hand Gyro and his crew, when they attempted to flee Fish-Man Island. The human pirates were left alive and were allowed to surface to the New World in order to spread the word of the terror of the New Fish-man Pirates. Hody declared that he and his crew would take Fish-Man Island by force and show the world that fish-men are the supreme race. Outside Fish-Man Island, Vander Decken IX was frustrated that he had not received a reply from Shirahoshi for ten years. He then threw a giant axe with the princess as the target.
Decken gleefully stated that Shirahoshi’s fate is either marriage to him or death. Decken and his crew, the Flying Pirates, then went to the Fish-Man District and formed an alliance with the New Fish-man Pirates. Once the Straw Hats arrived at the palace, Luffy wandered off in search for food and by accident met Shirahoshi when he stumbled into her room, and onto her. Shirahoshi was scared and cried continuously until Luffy saved her from the axe thrown by Decken. Once she calmed down, the two started talking and Luffy offered to take her outside, with him being the bodyguard.
In the meantime, Neptune and the Ryugu Palace received a message from Prince Fukaboshi, telling them of Madam Shyarly’s prediction and that the Straw Hats were suspected of kidnapping mermaids. Neptune and the palace guards attempted to capture Nami, Usopp, Brook, and Zoro. They did not succeed, as the four Straw Hats defeated and tied up Neptune and his guards, succeeding in an accidental takeover of the palace. At Coral Hill, Sanji and Chopper defeated the Ammo Knights trying to arrest them and after the fray, they found a wounded Hatchan at a beach with arrows in his back. Hatchan was unsuccessful in his attempt to reason with Hody Jones and Decken sent Hatchan running by throwing arrows at him.
Fukaboshi and his brothers returned to the palace, but the connection corridor has been closed off. Unable to enter the palace, Fukaboshi negotiated with Zoro and revealed Jinbe’s message. At some point after that, Hody Jones and Vander Decken IX began their plan to invade Ryugu Kingdom. Decken threw Hody’s human captives to Shirahoshi’s tower. After they landed, Brook and the Minister of the Right went to investigate.
By the time they arrived, Luffy, Megalo, and Shirahoshi had left the tower. Zoro defeated the human pirates but one of them managed to open the main gate and the connecting corridor to the palace, allowing the newly allied New Fish-man Pirates and Flying Pirates to invade the palace. Vander Decken IX then flew off on a piece of coral after learning that Shirahoshi was gone. Hody stayed behind and attacked the already tied up guards and king. Zoro then ordered for everyone to be released, saying that their deal was void since the hostages were harmed.
Hody proceeded to flood the palace and Zoro told Neptune to get Brook and Usopp to safety. Nami fled the palace with Camie and asked her to take her to the Sea Forest so she could talk to Jinbe. At the palace, Zoro proceeded to fight Hody, dealing a striking blow to him with one slash. Neptune created an escape route using Merman Combat: Ultramarine. The ministers and the guards quickly swam out of the palace.
Zoro, Usopp, and Brook then prepared to escape with Neptune and Hoe, but Hody, rejuvenated by taking an Energy Steroid, stopped their escape by seizing Neptune with one hand. The New Fish-Man Pirates then captured Neptune and the three Straw Hats. Meanwhile, Luffy and Shirahoshi (inside Megalo) were heading to the Sea Forest. As they passed over Coral Hill, Luffy saw Sanji, Chopper, and Hatchan who were in trouble with the locals. The locals believed that the Straw Hats were responsible for the mermaid kidnappings, though it was really Caribou’s doing.
Luffy jumped down to meet his friends and Megalo finally spitted out Shirahoshi, which caused an uproar with the locals. Decken then arrived on the flying coral and proposed to Shirahoshi, who rejected him. Enraged, Decken prepared to murder Shirahoshi, but Luffy intercepted him and pummeled him into the ground. Luffy, Shirahoshi, Megalo, Chopper, Sanji, and Hatchan all started heading to the Sea Forest after Luffy incapacitated Wadatsumi. At the Sea Forest, Jinbe waited for Luffy while sitting next to the grave of Queen Otohime.
Franky and the Thousand Sunny were nearby. Franky got acquainted with Den, who agreed to coat the ship. Robin soon arrived at the Sea Forest to search for a Poneglyph. Sometime after Robin went to the coral forest, Luffy and his group arrived. Luffy and Jinbe got reacquainted and Shirahoshi payed her respects to her deceased mother.
Nami and Camie appeared bearing terrible news about the Ryugu Palace. Jinbe then decided to reveal that he was responsible for setting Arlong loose into the East Blue. After discussing Arlong’s tyranny, the shaky relationship between humans and fish-men, as well as the conflicting ideals of Queen Otohime and Fisher Tiger, Jinbe started telling his story with the Sun Pirates. Upon finishing the story, Hody appeared on a live broadcast, stating that he would execute King Neptune, who was held captive, at Gyoncorde Plaza, and then take over as the new king of Ryugu Kingdom. He further stated that he would kill everyone who signed Otohime’s petition for pro-human/fish-folks relationship, considering them as traitors.
Finally, he planned to kill the Straw Hat Pirates for crushing Arlong’s ambitions two years ago, and that Zoro, Usopp, and Brook were locked in a room where they would be drowned in three hours, the same time that Neptune was to be executed. At Gyoncorde Plaza, the three princes attacked in an attempt to stop Hody, but ended up being captured. Jinbe, Shirahoshi, and Megalo tried to save the four royal captives, but ended up falling into a trap and being captured as well. Hody then revealed to the entire island that he was the one who assassinated Otohime a decade ago. At the same time, Decken, who was devastated at being rejected by Shirahoshi, threw the entire ship Noah at her in an attempt to destroy her and the entire island.
Shirahoshi stated that she knew all along that Hody was the assassin because Megalo, the only witness, informed her, but she chose not to tell due to her mother’s final wish. Hody mocked her and then prepared to kill Neptune. The residents of Fish-Man Island then decided that they rather have their island destroyed by Straw Hat Luffy as Shyarly predicted than have Hody as their new king, going as far as to shout out for him. Luffy, hiding in Megalo’s mouth all along, jumped out to stop Hody from performing the execution. Nami took the World Noble’s letter from Hody, as well as the key for the chains that restrained the royal family and Jinbe, the latter which was used by Robin to free the captives.
Franky then arrived on the Thousand Sunny to attack the New Fish-man Pirates, and Hoe saved the princes and the king. Zoro, Usopp, and Brook, having been freed by Pappag, also arrived along with Sanji and Chopper. The entire Straw Hat crew and Jinbe prepared to fight against the New Fish-man Pirates and the 100,000 outlaws from the Fish-Man District that they had brought along. The Straw Hats and Jinbe overpowered Hody’s forces with their two years of intense training, overpowering the 100,000 with a mere force of 10. The Kraken, Surume, betrayed the New Fish-man Pirates and fought for Luffy, having befriended the young pirate earlier.
Hody himself tried to fight against Luffy but was only beaten down repeatedly. As the citizens of the island looked on with awe, the “Ship of Promise” Noah suddenly descended onto the bubble of Fish-Man Island, aiming directly at Shirahoshi. With Wadatsumi falling off the ship and onto the plaza, the people knew it was Vander Decken IX’s doing. Everyone was shocked as Decken, who was on board of the ship, declared the end of everything as the ship was colliding with the island’s bubble. Shirahoshi fled the plaza to guide the ship away, offering her life to Decken to protect the safety of the rest of the island.
Hody, getting back up from his beating, climbed onto Noah to deal with Decken’s insanity and deviation from the original plan. Luffy had Sanji boost him up onto the ship to stop Decken. After a brutal battle, the Straw Hat Pirates defeated the officers of the New Fish-man Pirates, and Hody and Decken were both arrested. Shirahoshi summoned Sea Kings, who helped stop Noah from falling, and Luffy, having suffered major blood loss from his battle with Hody, got a blood transfusion from Jinbe, thus abolishing the ancient law that forbade humans and fish-kind from donating blood to each other. At the Ryugu Palace, Caribou released the mermaids that he had kidnapped but had stolen all the treasures in exchange. With that notice, King Neptune declared that, although they did not know of Caribou’s identity yet, the Straw Hat Pirates were indeed innocent. The island later found itself in crisis over not being able to pay Emperor Big Mom her monthly tribute of 10 tons of candy. After Luffy, Zoro, and Sanji took the stolen treasures from Caribou, they encountered Pekoms and Tamago at the Candy Factory. While speaking to Big Mom, Luffy declared that he would come to the New World and defeat her in order to make Fish-Man Island his territory. The Straw Hats later left the island, with the citizens bidding them farewell, and Neptune reminding his sons not to forget the debt.
