Fish-Man Island is the underwater home of the Fish-Men and Merfolk races, situated on the ocean floor 10,000 meters below sea level, directly underneath Mariejois. It is located inside a giant hole inside a deep trench that goes underneath the Red Line, encased inside a giant bubble. It has a section inhabited mostly by Merfolk and another mostly by Fish-men. However, mixed marriages between the two races are allowed. Fish-Man Island has endured a long history of prejudice by humans that has placed it under the protection of influential pirates at least three times in the story. Its location between Paradise and the New World makes it a frequent stop for many pirate crews. Thanks to being located inside a giant bubble, it allows land-races to breathe and live inside, while the giant tree Eve provides light hundreds of meters below the sea. The great ark Noah lies nearby the main island, built over 800 years ago to carry the island's population and realize their long held dream of moving to the surface. Built around the Noah is the Fish-Man District, a hotbed of crime and racism towards humans, and the headquarters of the New Fish-Man Pirates.
It is also the main setting of the arc of the same name.
- Awesome Underwater World: Fish-Man Island is known as an "underwater paradise" and truly deserves its title. It's a bright and outlandish version of Atlantis, with colorful buildings made or covered by giant corals.
- Fantastic Racism: Fish-Men and Merfolk have been the subject of racism and slavery by humans, especially the Celestial Dragons. As a result, the inhabitants of Fish-Man Island harbor a lot of grudges against humans, to the point they've become ingrained in the entire society, a problem which Otohime fought hard to remove. It gets partially solved only after the Straw Hats save the island, proving not all humans are bad.
- Tragic Dream: The Fish-Men and Merfolk have desired to move onto the surface for over 800 years, yet they've never succeeded because of Fantastic Racism. They nearly give up the dream when Luffy almost destroys the great ark Noah, that is supposed to carry them, to prevent the ark from crashing into the island, and then when King Neptune almost attacks the World Nobles to protect his daughter, reasoning that a world governed by such corrupt figures isn't worth living in.
- Underwater City: The city is located below the Red Line, inside a giant bubble, therefore allowing land-races to breathe in the island. Being thousands of meters underwater, it's very difficult to reach, and only 30% of all ships survive the journey.

- Overprotective Dad: King Neptune kept his gigantic daughter Shirahoshi locked up in a tower for ten years to keep her admirer's tokens of "affection" from reaching her. Quite justified though, since Shirahoshi has a very fragile personality and her admirer is a criminal Stalker with a Crush whose 'tokens' are engraved weapons which target her when thrown thanks to his Devil Fruit power. Quite a few of them can be seen embedded in and around the doors leading to her room.

- Verbal Tic: Often uses "-Jamon" to end his sentences.

Debut: Chapter 621 (Manga), Episode 540 (Anime)
A Goldfish Mermaid and the former queen of the Ryuguu Kingdom. Unlike Fisher Tiger, she wants a peaceful co-existence with the humans and spends most of the time fighting for this cause, even if hardly anyone support her. After making a deal with the World Nobles, many begins to support her and the idea of Fish-men living with humans, until she's assassinated. Her subjects are still loyal to her and her beliefs however.
- 100% Adoration Rating: Deconstructed. Otohime as always been beloved by everyone because of her kind and empathic nature. Even when she was a young and rebellious teens, the royal guards can't hide their admiration. This admiration is also what allows Otohime to became a queen, since she's already beloved in her younger days and the royal guards suggest Neptune to marry her. Unfortuantely, being loved doesn't mean everyone agrees with you and Otohime has to fight a lot to have people support her cause. However, because she's so popular, Hody Jones kills Otohime to stop her beliefs and the plans of a co-existence with the humans.
- All-Loving Hero: Exaggerated. Otohime can make a violent thief forced into a criminal life by poverty to reconsider his choices by pleading with him, then crying profusely as she sympathizes with his pain, of course after she slaps him several times. She's also immensely influential and gives passionate speeches, as she's adored all over Fish-Man Island. This trait is taken to the absolute extreme when she not only takes a bullet for a Celestial Dragon, who are the biggest Hate Sink of the entire series, but then leaves with him to the Holy Land and successfully negotiates with the other World Nobles. At the reverie, said Celestial Dragon shows to have been moved by Otohime's actions and has become a better person when he saves Shirahoshi.
- Animal Motifs: More subtly, she has a dragon motif, as shown with the Dragon Palace, indicating her royal status and her contrast to Fisher Tiger, but the more evident one is her Fish-man type: the goldfish. The goldfish is traditionally a simple and weak fish, and Otohime is physically very weak, to the point she breaks her own bones by simply slapping a person, but in contrast has a very strong and determined personality.
- Armor-Piercing Slap: Parodied. In her debut Queen Otohime puts so much force into slapping a mugger that she breaks her own hand. And starts crying because she feels sorry for his desperation. And then she hits him again for breaking the law.
- Badass Pacifist: Otohime abhors violence, spreads her belief through a completely pacific way, and is willing to bear all the pain and sadness of her people so nobody else has to cry or bleed ever again. While she cannot fight, Otohime has a very strong personality and doesn't back down when someone comments her beliefs, she verbally beats the god complex out of one of the Celestial Dragons and convince him he was human like anyone else and not above everyone.
- Break the Cutie: Queen Otohime spends most of the time collecting signatures for her cause to have Fish-men and humans live together. Many children sign her petition, making Otohime very happy, until they come back to retrieve the papers because their parents don't approve it and think the humans are in the wrong. Otohime comes back home as cheerful as usual, until she locks herself in her room and bursts into tears.
- Deceased Parents Are the Best: Otohime is a loving and caring mother but dies eight years before the beginning of the series. Her children fondly remember her and have inherited her ideals.
- Determinator: Even if nobody else support or believe in her cause, Otohime keeps on fighting for a future where humans and Fish-men live together without prejudice. Otohime feels broken when many kids retrieve their signatures following Fisher Tiger's death, but she doesn't give up and, eventually, it leads to Otohime having a discussion with the World Government itself about the relationship between Fish-Man Island and the rest of the world.
- Drowning My Sorrows: After everyone retrieve their signatures for Otohime's cause, following Fisher Tiger's death, Otohime goes back home putting an happy smile but, after she's locked in her room, she cries and drinks a lot of wine. While drunk, Otohime calls out her people for their cowardice.
- The Empath: Otohime uses her Observation Haki to sense someone's feelings, making her a very beloved queen.
- Establishing Character Moment: In her introduction, Otohime stops a thief, slaps him, breaking her hand in the process, and scolds him for having stolen. After the thief tries to justify his theft to feed his ten children, Otohime replies that it's even worse since then he would be a bad example for his children, but at the same time she cries and apologizes for not having noticed his suffering. This scene establish Otohime as a caring and loving queen who fights for justice, as well as a physically frail but mentally strong mermaid.
- The Extremist Was Right: Otohime represents the extreme pacifism, in contrast to Fisher Tiger's violent course of action. She tries to reach her goal through exclusively pacific methods, and she insists on rescuing a stranded Celestial Dragon, even protecting him from his former slaves exacting vengeance and taking a bullet in his place. Her extreme actions allow her to get the Celestial Dragons to support her petition, and it pays off even bigger when said Celestial Dragon becomes a nice person, and would go on to free his slaves, rescue her daughter from an attempted kidnapping, and pledges his support for Fish-Man Island. Fisher Tiger himself, despite holding a huge hatred toward humans, in his final words admits that Otohime is right.
- Foil: Otohime and Fisher Tiger, being based off Martin Luther King and Malcom X respectively, represent two different ways to fight racism and prejudice. Otohime is idealistic and uses pacific methods to reach a coexistence between humans and Fish-men, while Fisher Tiger is cynic and thinks humans and Fish-men must remain separate and frees the slaves with violent assaults (but forbids anyone to kill humans). They have a mutual respect for one another despite their difference in beliefs regarding humanity, and both are assasinated and in their last words they warn about the danger of spreading more hate.
- Fragile Speedster: Otohime is fast enough to outrun her soldier escort and dodge bullets but her body is extremely fragile, to the point she breaks her hand slapping the man who shot at her.
- Friend to All Children: While Otohime loves and is loved by most citizens in her kingdom, she cares a lot about the children, spending a lot of time talking to them, benevolently disciplining them, and teaching them of the life on the surface, and insisting that they shouldn't grow up to hate humans like many of the adult Fish-men and mermaids do. This is because she's aware of the danger of spreading the hate to the new generations and wants to prevent it.
- Good Parents: She is seen to be very close with all four of her children. Even when she's exhausted from her work and depressed when her people no longer support her cause, it doesn't stop her from putting on a smile for her kids and spending time with them.
- Go Out with a Smile: In her last moments, Otohime smiles as Fukaboshi promises her that he and his brothers would take care of Shirahoshi and that they'll make sure that the signatures from their people would be collected.
- Hair of Gold, Heart of Gold: Otohime has blonde hair, complementing her golden palette fitting for an idealistic and pacific woman.
- Harmful to Minors: Otohime believes that the best way to have children grow as better people is to leave them good examples. When a thief tries to justify his actions because of his ten children, Otohime remarks that it makes things worse since, aside of stealing, he would be a bad example for his children as well. This line of thought is also Otohime's course of action to extirpate the prejudices between Fish-men and humans in the future generations. When the inhabitants wonder why has she taken the bullet for an assholish Celestial Dragon, Otohime remarks that children are watching.
- Hidden Depths: While at first Otohime appears to be the classic idealistic person, during her drunken rant, it's revealed revealed that part of her motivation to campaign is anger at the injustice of a world where opportunities for Fish-men are forever out of reach for no other reason than because they were Fish-men, and she both understands and accepts that some Fish-men can never forgive and reconcile with humans, focusing instead on making sure they do not pass their hatred on to the younger generation.
- The High Queen: Otohime is the beloved queen of Fish-Man Island and, despite her noble appearance, she spends a lot of time among the citizens to make her kingdom a better place. Even years after her death, the citizens fondly remember her and are heartbroken when they're forced to step on her picture.
- Hot Skitty-on-Wailord Action: Otohime is married with Neptune, who is several times her size, and together they have four children. While the three boys, as kids, are smaller than Otohime, Shiraoshi, is larger than her even as a baby.
- Huge Guy, Tiny Girl: Otohime is a short and delicate mermaid while Neptune is enormous, bulky and multiple times her size.
- In Vino Veritas: When her people, even those who have previously supported her cause, starts backing out in the wake of Fisher Tiger's death, Otohime goes back home and gets completely smashed, then gets on the radio and viciously calls out her subjects for their cowardice, telling them that this kind of action would never improve their relationship with humans.
- Inelegant Blubbering: Despite her elegant look and mature personality, when she cries, Otohime covers her face with snot and tears, as shown when she cries out of empathy for a thief and out of desperation when everyone take back his/her signatures for her cause.
- Innocent Blue Eyes: Otohime has big blue eyes, similar to those of a child, that emphasize her purity and idealism.
- Ki Manipulation: Despite not being a fighter, Otohime is capable of using Observation Haki as shown when she dodges a gun's bullet. However, she mostly uses it to sense the others' feelings.
- MayDecember Romance: Otohime is 24 years her husband Neptune's junior but the two deeply love each other and, even a decade after her death, Neptune still mourns her.
- Missing Mom: Otohime is killed ten years before the events of Fish-Man Island, leaving her children without a maternal figure since they were young. The one hit the most is Shirahoshi, who can't even get to properly pay her respects to her mother until Luffy came along, because Vander Decken's continuous threats force the princess mermaid to remain locked in her room.
- Non-Action Guy: Discussed when Otohime is offered to have a talk with the World Nobles in the Holy Land. Neptune offers to go in Otohime's place since she's very frail but Otohime refuses, because it proves humanity's tolerance if even someone weak like her can go to their nation and return unharmed.
- No Celebrities Were Harmed:
- The Martin Luther King Jr. to Fisher's Malcolm X. Her having been assassinated for her cause, in broad daylight via sniper gun shot, just as MLK was, also draws parallels.
- The New Fish-Man Pirates force the island's citizens to step on a Fumi-e with her image, a reference to how Christians in Japan were forced to step on an icon of Jesus or the Virgin Mary.
- Only Six Faces: Averted. Contrary to the majority of attractive female women, who either have Nami's or Robin's face, Otohime is beautiful and has a face clearly distinct from the other female charaters.
- Posthumous Character: Otohime is killed eight years before the beginning of the series with a gunshot, not unlike Martin Luther King Jr., by Hody Jones. Her actions and her desire to bring down racism between humans and Fish-men is one of the main themes of the Fish-Man Island arc.
- Rags to Royalty: Otohime was born as a common inhabitant of Fish-Man Island and became queen after marrying king Neptune, despite this, both as a common person and as a royal, Otohime keeps her ideals to make a world where humans and Fish-men can coexist.
- Reasonable Authority Figure: Otohime is a just queen who never condemns anybody's actions, even if they're wrong, and empathize with all of her people. When a thief explains his situation, Otohime apologizes for not having felt his suffering.
- Royals Who Actually Do Something: Otohime has been actively fighting racism and prejudice since she was a teenager and, even after marrying king Neptune, remains involved in social issues. In her debut she stops a thief and convinces him to become a better person with a passionate speech, and every day she tries to collect signatures for her cause. After she saves a World Noble, Otohime even gets the chance to go to the Holy Land, where no merfolk has ever been allowed to go, to discuss about a coexistence between Fish-men and humans.
- Silk Hiding Steel: Despite being as frail as she looks, Otohime is arguably the bravest and most heroic woman in the One Piece universe, and her strong personality helps to fight the racism in Fish-Man Island. Thanks to her will, Otohime obtains a deal with the racist World Nobles after having gone all by herself to the Holy Lands.
- Soapbox Sadie: Otohime has been a supporter of her pacifistic and inclusive ideas since she was young, and at the time she often organized protests against the racism present on Fish-Man Island. Unlike most examples, however, she was beloved by nearly everyone: even the royal guards could barely hide their admiration for her.
- Taking the Bullet: When a Celestial Dragon ends up on Fish-Man Island, he arrogantly orders the inhabitants to bring him a doctor, whlie bragging his status as World Noble. Said inhabitants, however, decides to give him a slow and painful death for all the pain the Celestial Dragons inflicts on others but, when they're about to shoot him, Otohime jumps in the middle and gets non-fatally shot in his place. This action eventually leads to St. Miosgard to become a good person.
- Tender Tears: Like her daughter, Otohime cries at the drop of a hat, because her heart is so pure and kind and she emphatizes a lot with her people.
- Tiger Versus Dragon: One of Otohime's Animal Motif is the dragon, to put her in contrast with Fisher Tiger's tiger motif and emphasie their different ideologies and ways to fight prejudice.
- Too Good for This Sinful Earth: Neptune laments that someone as innocent as her would die while he, who has killed plenty of humans during his life, would come off as a hypocrite trying to sustain the dream of human/Fish-man harmony.
- Ugly Guy, Hot Wife: While Neptune is burly, hairy and with a pointy nose, Otohime is a beautiful mermaid. Justified since Neptune is much older than her.
- Wide-Eyed Idealist: Otohime is a firm believer of a peaceful coexistence between humans and Fish-men, despite her own people being skeptical at best. While she's aware some Fish-men's hatred cannot go, she believes the future generations will have a better relationship if the prejudice isn't passed on, and she keeps her own beliefs even as she dies.
"Mermaid Princess" Shirahoshi
Voiced by: Yukana (JP), Bryn Apprill (EN)
Debut: Chapter 612 (Manga), Episode 531 (Anime)
The princess of the Ryugu Kingdom and the youngest child of King Neptune. A surprisingly huge Giant Smelt-Whiting mermaid. She is really huge, but has a very fragile personality. She's kept locked away in the castle tower to keep Vander Decken from killing her with his Devil Fruit ability. Because of this isolation, she has a poor understanding of the world outside, but later develops an interest in it thanks to Luffy's help.
- All-Loving Heroine: She inherited this from her mother. She knew who her mother's murderer was and she kept it to herself for 10 years to honor her mother's last wish to bear no ill will against her killer, and prevent others from seeking vengeance. However, this takes a more disturbing twist when we find out that the one who killed Otohime was not one of the humans she was trying to make peace with, but a Fish-man who was sick and tired of this very quality.
- Apocalypse Maiden: She's the modern incarnation of the ancient weapon Poseidon, who had the power to control the Sea Kings and potentially destroy the world.
- Badass Pacifist: She may not have any fighting skills (that she's aware of, anyway), but it still takes guts to brave herself against a gigantic projectile that's coming at her, and try to lure it away from the island to protect its citizens.
- Bare Your Midriff: She is a mermaid after all and wears only a bikini. During the Reverie, she wears a shirt that still leaves her midriff exposed.
- The Beastmaster: While a common trait among Fish-men and Merfolk, in Shirahoshi's case it's revealed that she has the power to summon and control huge (and we mean HUGE) Sea Monsters in cases of distress. This is why Vander Decken wants to marry her. See also Monster Lord below.
- Because You Were Nice to Me: Her initial reaction upon seeing Luffy for the first time is to cry and call for her dad but, after Luffy deflects an axe aimed at her, Shirahoshi quietly hides him from the Minister of Right.
- Big Little Sister: Shirahoshi is the youngest of Neptune's children and the only one to have fully inherited his size. While her brothers are relatively big as well, even as a baby, Shirahoshi was already bigger than them.
- Blush Sticker: She has a permanent blush on her cheeks which just adds to her cuteness and emphasizes her shyness.
- Boobs of Steel: Seemingly averted until you realize that she's the modern incarnation of the Ancient Weapon Poseidon and possesses the power to control Sea Kings and possibly use them to tear islands apart — fitting, considering she has one of the largest busts in the series.
- Commonality Connection: She quickly bonds with Vivi, Rebecca, the Tontatta, and Dalton over their shared friendship with Luffy.
- Cowardly Lion: When the colossal ancient vessel Noah, now targeted towards her, flies careening towards Fish-Man Island, Shirahoshi unhesitatingly prepares to give her life to save her people by swimming away from Fish-Man Island so the vessel will crash into her and her alone. Ladies and gentlemen, the definition of courage itself. Even Luffy notes that she's not a coward, just a crybaby.
- Cry Cute: She's pretty much known for crying and looking cute while doing it.
- Cute Giant: Shirahoshi is a gigantic mermaid but is just as beautiful as most One Piece women, while her introverted and childish personality make her more adorable in spite of her size.
- The Empath: All There in the Manual reveals she has inherited her mother's form of Observation Haki, though this has yet to be shown in the manga.
- Gag Boobs: They're huge even relative to her size. Luffy is able to (unintentionally) use them as a trampoline.
- Generation Xerox: Her personality is quite similar to her mother's.
- Gentle Giant: Shirahoshi has inherited her father's huge size and her mother's kindess. Even if she's easily scared, she tries her best to help her people and, after Luffy saves her life, she hides him to protect him from the royal guards.
- Giant Equals Invincible: Complete aversion. Despite being the largest member of the royal family alongside her father, she has no fighting skill whatsoever. Though she promises to Luffy to stop being a crybaby, and considering her power to command Sea Kings, she will improve a lot.
- Giant Woman: Shirahoshi is one gigantic mermaid, far larger than the Ryugu Kingdom merfolk or even her big brothers. She's the only one retaining the gigantic size of her father, Neptune. She's also very pretty (it's often said the seat of World's Most Beautiful Woman is shared between Boa Hancock and her) and surprisingly Prone to Tears for her size.
- Girl in the Tower: She was confined to a tower in the Ryugu Royal Palace after Vander Decken started threatening her with his "love letters".
- Heroic Sacrifice: Attempted. As soon as she realizes the Noah is coming after her specifically, she hightails it off Fish-Man Island to lure the ship away from the people. It almost works, but then Decken is rendered unconscious and the ship begins falling down to the island.
- Honor Before Reason: Deliberately hides her knowledge of the fact that Hody Jones is her mother Otohime's killer to honor her mother's wishes and stop the cycle of hate, although this leaves him able to build up enough power over time to attempt his coup. However, the Straw Hats praise her devotion and, after Hody is defeated, the cycle of hate is broken for good.
- The Ingenue: She's very innocent with little knowledge of the outside world, and also is prone to crying.
- Innocent Blue Eyes: She's got light blue eyes and she's innocent to a fault.
- Irony: Smelt-whiting are usually tiny, but Shirahoshi is the largest mermaid seen so far.
- It Runs in the Family: Neptune is a pretty big guy, so her size is not that surprising. Could also apply to her powers, which are the same as with a previous mermaid princess: Poseidon.
- Kawaiiko: Every home should have one. Unfortunately, too big to take home with you.
- Living Macguffin: Being the current incarnation of world destroying weapon makes her one by default.
- MacGuffin Super Person: Vander Decken wants to marry her so he can use her ability to control Sea Kings.
- Monster Lord: It's not obvious at first, but The Sea Kings who came to her aid state that every few hundred years, "(their) queen will be born in the form of one of the merfolks". This isn't the ability to simply tame wild beasts a la The Beastmaster, she's their one true ruler by birth.
- Ms. Fanservice: She's as sexy as she is cute, the very sight of her is enough to turn Sanji to stone the first time he lays eyes on her, though in fairness he's still recovering from his two years trapped in the Kamabakka Kingdom.
- Nice Girl: She's kind and very polite to everyone, even her stalker.
- No Social Skills: Justified, since she's spent the last ten years of her life stuck in her room. Shirahoshi is very shy, socially awkward and afraid of strangers, to the point she bursts into tears and calls her father when Luffy enters her room. After befriending Luffy and facing Hody, Shirahoshi becomes braver and more extroverted, but still has some troubles when interacting with strangers. The only exceptions are Vivi and Rebecca, with whom she quickly bonds through their shared friendship with Luffy.
- Outnumbered Sibling: Shirahoshi is the only daughter of king Neptune, as well as the youngest child. Her three older brothers are very protective toward their sensitive and naive sister.
- Person of Mass Destruction: She has the ability to summon and communicate with Sea Kings, a power that's said to be able to, if used incorrectly, destroy entire islands. Shirahoshi isn't the first to have this power, as the Poneglyph of Shandora describes a weapon called "Poseidon", which was actually the Mermaid Princess at the time this was written. In such a sense, Shirahoshi is the new Poseidon.
- Poor Communication Kills: As it turns out, she knew all along Hody Jones was the one who murdered her mother Otohime for supporting human-Fish-man coexistence, but deliberately withheld the information in order to honor her mother's last wish to bear no ill will against her killer and prevent others from looking for vengeance. While her intentions were noble, her decision to keep quiet allowed Hody to gain enough power to easily overwhelm Fish-Man Island's military and plot a coup; Hody even takes the time to rub it in her face.
- Princess Classic: She's the princess of Fish-Man Island. She's innocent, kind, and so utterly committed to peace between Fish-men and humans that she doesn't reveal the identity of her mother's killer for a decade. Her beauty is said to rival that of Boa Hancock. Her clothing is about as pimped-out as the traditional mermaid sea-shell halter will allow. About the only way she doesn't play this trope straight down the line is that she turns out to be not so defenseless, having the nigh-apocalyptic power to control Sea Kings.
- Prone to Tears: For someone so huge she's quite fragile, she cries easily and doesn't take being yelled at very lightly. She inherited this trait from her mother, but completely Up to Eleven.
- Rapunzel Hair: She has very long hair.
- Rose-Haired Sweetie: She has long pink hair, and she's very sweet and innocent.
- Seashell Bra: Or rather pearls.
- Sheltered Aristocrat: Due to being locked up in the castle tower for most of her life, Shirahoshi has very limited knowledge of the outside world and asks Luffy about the sun, animals, and forests.
- Silk Hiding Steel: Do not underestimate her just because she is a kind-hearted crybaby; it takes strength of character to keep the promise of not hating your mother's murderer and when the lives of her people are on the line, she's as brave as any warrior in the One Piece universe.
- Tears of Fear: Especially when first introduced, Shirahoshi is scared of anything strange to her, and her reaction is bursting into tears and calling for help.
- Tender Tears: Tends to cry a lot. Though given the situation she's lived in for most of her life, it's kind of understandable.
- The So-Called Coward: Like daughter like mom, it's her kindness that makes her a hero. See Cowardly Lion above for more details.
- The Ugly Guy's Hot Daughter: Neptune is no looker, but Shirahoshi is very lovely and absolutely huge.
- Walking Spoiler: Due to being the living incarnation of Poseidon.
- The World Is Just Awesome: Come the Reverie arc, she's in complete awe of the world above the sea, and wishes for her island to be moved to surface level so that her subjects can see for themselves how beautiful the world is.
- World's Most Beautiful Woman: Many claim that her beauty rivals that of Boa Hancock.
- You Gotta Have Blue Hair: She has pink hair.
- You're Not My Type:
- She says this is the reason that she won't marry Vander Decken. Considering that she has been confined to a tower for a decade to protect her from weapons he is constantly throwing at her, it shocks everyone that this is her issue.
- It shows up again when she's attending Reverie and a few of the nobles approach her with marriage proposals of their own, prompting a very flustered Shirahoshi to tell all of them this, much to everyone's shock. She unintentionally leaves several of the nobles feeling slighted.
- Your Size May Vary: While her canonical height of 11.87 meters is hardly small, it's hardly as huge as the manga often makes her out to be. She's shown big enough that Luffy can fit in her hand, but, in her typical sitting position (which she's almost always in due to being a mermaid), she's barely equal in height to the likes of Whitebeard and Katakuri.
Voiced by: Kentaro Ito (JP), Jarrod Greene (EN)
Debut: Chapter 609 (Manga), Episode 528 (Anime)
The eldest of the three princes of the Ryugu Kingdom and a shark merman. He assists Luffy in his battle against Hody Jones.
- The Comically Serious: He's a permanently grim, serious guy who exists in One Piece and ends up as an ally of Luffy, the resident Fun Personified. This trope comes with the territory.
- Disappointed by the Motive: He furiously confronts Hody, demanding to know why he hates humans so much and what they did to him to make him into such a monster. He's shocked to discover that Hody has never actually had any bad experiences with humans, and was just raised to hate them without even knowing why. Fukaboshi proceeds to send out a mass-communication admitting that Hody's grudge is "one without substance".
- Distressed Dude: Becomes this for a while alongside his brothers and father, after being defeated by Hody.
- Face of a Thug: He's a much more decent, reasonable guy than his narrow eyes, jagged teeth, and grim, intimidating demeanour suggest.
- Gonk: Not as much as his brothers though, as he at least has a Heroic Build. The anime also makes his face much less angular.
- Gut Feeling: When royals from all over the world attend the Reverie in Mariejois, Fukaboshi subtly leads his family away from using the Celestial Dragons' travelator, because he has a bad feeling about it. It turns out that the travelator is operated underneath by slaves who have to pull the walkway forward.
- Kamehame Hadoken: Is able to use the "Ultramarine" technique, just like his father.
- Making a Splash: Again, "Ultramarine", which is a huge blast of torrential water.
- Meaningful Name: Fuka means "shark" or "dogfish", fitting Fukaboshi's Fish-man type.
- Only Sane Man: Among his family.
- Perpetual Frowner: He has exaggerated Tsurime Eyes in a permanent glare. Even when he's wearing a friendly smile (which isn't often), he manages to make it look grim.
- Prongs of Poseidon: His weapon is a large trident, fitting for the firstborn of an aquatic royal family.
- Reasonable Authority Figure: Like his father, except he's a bit smarter too.
- Rousing Speech: Fukaboshi made one at his mother's funeral to keep the spirit of the subjects high.
- Royals Who Actually Do Something: He is referred as one of the strongest of the Neptune Army. Possibly the strongest too.
- Shark Man: Specifically, Dogfish shark.
- The Stoic: It really sticks out when he's next to his more quirky brothers.
- Taking the Bullet: When Hody is attacking his soldiers, Neptune throws himself in the way of Hody's water arrows. Hody calls him a fool for doing this.
- Threatening Shark: Subverted. Fukaboshi is a Shark merman and has an intimidating face, but is quite calm and reasonable.
- Warrior Prince: Definitely, as one of the strongest soldiers in Ryugu Kingdom's Neptune Army.
- You Gotta Have Blue Hair: Large, wavy, blue-colored locks.

Age: 23 (Ryuboshi) 20 (Manboshi)
Debut: Chapter 609 (Manga), Episode 528 (Anime)
Respectively the second and third oldest prince of the Ryugu Kingdom. Ryuboshi is a slim oarfish merman while Manboshi is a plump opah merman. Both like singing and dancing and even talk while singing.
- Acrofatic: Manboshi has a rotund, stocky appearance, but like his brothers he's a very nimble fighter.
- Big Fun: Manboshi is cartoonishly fat and very jovial and loves to dance. It was invoked ten years before to cheer up his "little" sister after their mother was assassinated.
- Bunny-Ears Lawyer: Despite their goofy and cheerful behaviour, Ryuboshi and Manboshi are very competent princes. During the Reverie, they remains cheerful but in a much more level-headed way than usual, as they are aware of the importance of the event.
- Cerebus Retcon: They're constantly cheerful and upbeat, more often than not singing while talking and dancing for no reason. They began this habit ten years before the events of Fish-Man Island to cheer up Shirahoshi when their mother, Otohime, was shot and to prevent her from accidentally unleashing the Sea Kings on Fish-Man Island.
- Crouching Moron, Hidden Badass: At first, they appear to be two goofy and upbeat mermen but, when is necessary, they are able to fight and defeat giant sea monsters. They're also aware of how to behave during the Reverie, during which they drop their singing and dancing habit.
- Dissonant Serenity: They begin dancing and singing when their mother bleads to death beside them. This is a deliberate act they put on to reassure Shirahoshi everything is fine so she doesn't inadvertently summon Sea Kings in her distress, but Ryuboshi and Mamboshi can't hold back their tears as they perform.
- Dual Wielding: When in combat, Ryuboshi wields two long rapiers.
- Fat and Skinny: They're constantly together, but are easy to tell apart because Ryuboshi is very slim while Manboshi is fat. This also reflects their fish-type: Ryuboshi is an oarfish (a very long, eel-like, fish) merman and Manboshi is an opah (a stocky fish) merman.
- Punny Name: Manboshi likes to do the Mambo dance.
- Stepford Smiler: Ryuuboshi and Mamboshi's "dancing and singing" routine comes from their last attempt to cheer up their little sister, who at the time was just a kid, right after seeing their mom shot and dying.
- Verbal Tic: They both tend to sing while talking. Ryuboshi has also the habit of ending his sentences with musical scales, while Manbo often says "Akkamambo".
- Warrior Prince: They're the second and third sons of King Neptune and, while not to the extent of their older brother, Fukaboshi, they're both strong warriors, able to fight giant sea monsters.
- Walking Shirtless Scene: More like swimming shirtless scene but, Manboshi doesn't wear a shirt. Averted during the Reverie, in which he does wear one.
The Royal army of the Ryuguu Kingdom, lead by Neptune's three sons. It was created recently to contrast the threat of the vicious Van Der Decken IX, who is harassing Mermaid Princess Shirahoshi and wants to marry her.
- Blade on a Stick: The Minister of the Right wields a huge trident-shaped Halbeard.
- Cool Old Guy: The Minister of the Right, who looks like a warrior.
- Cool Pet: Shirahoshi owns a pet shark named Megalo.
- Incredibly Lame Pun: Their troops are the Ammo Knights. Ammo is a short-hand word for "Ammonite", i.e. fossilized snails, which their armor looks like. Also, Neptune's Whale mount "Hoe" means Whale in Japanese.
- Non-Action Guy: The Minister of the Left.

Debut: Chapter 69 (Manga), Episode 31 (Anime)
Hatchan, often called "Hachi", is an octopus Fish-man, former officer of the Arlong Pirates and a former member of the Sun Pirates. After the crew split up, he joined Arlong's crew and became the handler of the sea cow Momoo. When the Straw Hats came to take down Arlong, he was defeated by Zoro, and was imprisoned by the Marines. However, he managed to escape, and met the mermaid Camie after saving her from Sea Kings and Fish-man slavers. He opened up a seafood stand with her, fulfilling a childhood dream.
Later on, he crossed paths with the Straw Hats once again while they were heading for Fish-Man Island. He revealed that he felt bad about what had happened at Arlong Park, and decided to try and make it up to them and Nami by guiding them to the Sabaody Archipelago where they could have their ship coated for the underwater journey by Silvers Rayleigh, an old friend of his from before his pirate days.
- Acceptable Targets: All Fish-men are this, according to the citizens of Sabaody Archipelago in-universe.
- Affably Evil: During his time as a villain.
- All Love Is Unrequited: Hachi has feelings for an octopus Fish-woman called Octopako, but she rejects his proposal. He gets over it pretty soon and opens a takoyaki stand with Camie.
- The Atoner: In order to make it up to Nami and the other Straw Hats, he's even willing to take them to the most dangerous places in Sabaody Archipelago for a Fish-man to go. He reveals this after getting pummeled for his efforts (although he was fairly obvious about it when making fritters for the Straw Hats).
- Breath Weapon: As an octopus, he can squirt ink from his mouth.
- Carnivore Confusion: One way to look at the fact that he's an octopus-man who makes takoyaki. Although this is arguably justified, since octopi do eat other octopi.
- Chef of Iron: After leaving the Arlong Pirates, he opens a takoyaki shop. That doesn't mean he's lost his combat abilities.
- Day in the Limelight: He gets his own Mini-Adventure that details his adventures starting from his escape from the Navy and ending with him opening his own takoyaki stand. The cover page series reveals Hachi's Hidden Depths and prepares readers for his HeelFace Turn.
- Dumb Muscle: He is not very bright, but is one of Arlong's strongmen.
- Friendly Target: Misfortune always seems to be coming Hatchan's way. As if being defeated handily by Zoro wasn't enough, after his HeelFace Turn, karma decides to have his friends kidnapped, have him lose his girlfriend, be captured in the process of rescuing them, being shot by a World Noble, his ass getting kicked while defending the Thousand Sunny from the Marines, with Duval and Kuma, and being attacked with a hail of arrows by Van Der Decken putting him close to death.
- Funnel-Mouthed Cephalopod: Hatchan is octopus Fish-man and, among his octopus traits, he has a funnel-like mouth.
- Good Feels Good: Hachi's cover page story is basically an averted trope of No Good Deed Goes Unpunished. Every time Hachi helps someone, they are grateful and give Hachi something that helps him to help someone else. In the end, Hachi is able to save a whole town of catfish, who in turn build a ship for his floating takoyaki stand.
- HeelFace Turn: Nami isn't convinced until he got shot, and revealed he tried hard to earn their forgiveness but managed to mess that up. Luffy told him not to worry about it in his own way.
- Hero of Another Story: Let it be known that this guy has single-handedly saved Camie countless times. It just so happens that the people he clashes with when the Straw Hats are around are so much stronger than him...
- I'm a Humanitarian: His job at Sabaody Archipelago is making takoyaki. Subverted; he claims he uses other tentacled species.
- Impaled with Extreme Prejudice: By multiple arrows and a dagger. Darn You, Decken!
- Mr. Exposition: Ironically, he becomes this in Sabaody Archipelago, despite his previous status as Dumb Muscle. Justified, as the only thing he's expositing is the social position of Fish-men on Sabaody Archipelago, which was where he grew up. Plus, that sort of thing is really hard to ignore when it's the sort of cultural conditioning akin to being black under Jim Crow (arguably worse, as slaves can still actively be taken on Sabaody). The fact that he survived there as long as he did means he had to be aware of it. And after witnessing first hand what Luffy did in Arlong Park, he was more than aware how the Straw Hats would react to it.
- Multi-Armed and Dangerous: Being a octopus-man... with swords.
- Multi Wielding: Actually sextuple-wielding.
- Nice Guy: After his HeelFace Turn. Actually, even before that to an extent.
- Nobody Touches the Hair: Parodied in his fight vs Zoro, when Zoro cuts a piece from his hair.'"MY HAIR! You jerk! I'm gonna... I'm gonna... forgive you. I mean it's only hair, it'll grow back!
- Oblivious to Love: To Camie, unless he notices but doesn't want to encourage/embarrass her.
- Pet the Dog: His kind treatment of Camie and Pappagu.
- Reformed, but Rejected: While the Straw Hats accepted Hatchan and Nami was fine with him aboard since he would pose no threat even if he was still evil, she was still distrustful of him until he got shot.
- Simpleton Voice: In the 4Kids dub.
- Supreme Chef: His fried octopus is apparently quite delicious.
- Token Good Teammate: When he was with Arlong's crew.
- True Companions: This is the major reason he was with the Arlong Pirates: He was in the original Sun Pirates before it broke up, and went with Arlong towards the East Blue.

A young Kissing Gourami mermaid who dreams of being a fashion designer. She has a tendency to be eaten by sea monsters and kidnapped by slavers, having met Hatchan when he rescued her from one such incident. She helps him open a seafood stand after he saved her again from a group of Fish-man slavers. When she and Hatchan take the Straw Hats to the Sabaody Archipelago, her being kidnapped by slavers (yes, again) sets off a series of escalating From Bad to Worse moments for the pirate crew.
She is accompanied by a talking starfish named Pappagu, who constantly frets over her safety. Hatchan's friend Shakky teases her occasionally for having a crush on the octopus Fish-man.
- All Love Is Unrequited: Poor girl... made worse by how it's probably the only sympathetic depiction of romantic love in the story.
- Beauty Is Never Tarnished: Completely averted; she's damn cute, but also executes some of the most excellent Jaw Drops ever for a female in the series.
- Brain Bleach: Invoked in-universe when the Straw Hats meet her. As the last mermaid they met was decidedly less attractive, they bleach their memories of that mermaid so good-looking Camie is the first one that comes to mind. Especially Zoro, who literally wiped his own memory on the spot of their first mermaid encounter!
- The Chew Toy: Constantly eaten by Sea Kings and kidnapped by slave traders.
- Distressed Damsel: Turned Up to Eleven For Laughs. She notes that she and Pappagu have been eaten by sea monsters 20 times and captured by slavers (the same slavers, no less) about 30 times, and Hatchan always rescues them. Usopp calls her out on it, too.
- Neutral Female: Considering that she's a Distressed Damsel par excellence... Though be fair, there wasn't much she could actively do about it since she was stuck in a fishbowl with an exploding collar around her neck. Try picturing yourself like that and wonder if you could ever do something.
- Nice Girl: She's a real sweetheart, instantly befriending the Straw Hats the moment they met.
- Spell My Name with an "S": Camie? Or is it Caimie? Or maybe even Keimei? Both the manga and Funimation subtitles settle on "Camie", but fans, fansubs and the wiki vary on which spelling they use.
- Super Speed: Mermaids are among the fastest creatures in the sea, and Camie's no exception. When putting her mind to it, Camie can outswim the Flying Fish Rider's mounts, which are known as some of the fastest animals underwater.
- Wild Take: She has probably the craziest take◊ in the series (which is saying something) and it takes very little to set her off. (It's a reference to the species of fish she bears the tail of, Kissing Gourami.)
- You Gotta Have Blue Hair: Camie has green hair.

A beautiful, large Shortfin Mako Mermaid who runs the Mermaid Café in Fish-Man Island. Shyarly is also a well known seeress, and foretold great events like the coming of the Great Age of Piracy and Whitebeard's death. She recently freaked out when she predicted Fish-Man Island's destruction at the hands of a person wearing a "straw hat," which may implicate Luffy or Decken. She is also the younger half-sister of Arlong.
- Absolute Cleavage: Sports a minor one. Her hoodie covers her chest, but it has a frilled V-neck and Shyarly doesn't seem to be wearing anything underneath it.
- Berserk Button: Shyarly is usually extremely calm and polite... until someone is rude to her.
- Good Smoking, Evil Smoking: She uses one of those long cigarette holders like a high class lady.
- Hellish Pupils: Not only are her pupils slitted, but her irises are ovular.
- In the Hood: She's always wearing a hood.
- Large and in Charge: She owns the Mermaid Café and is surprisingly big for a mermaid.
- Nightmare Face: At Usopp and Luffy, when the latter once again asked if mermaids poop. Complete with fangs.
- Prophecy Twist: She foresaw the destruction of Fish-Man Island. Only it wasn't literal. Unless there's more to come, of course.
- Retcon: When she first appeared in a flashback in the manga, she was a teenager. However, Oda stopped and realized that if this were the case, Madame Shyarly would be really old by the time the present rolled around, and this did not match up with the age of her brother Arlong, so he went back and redrew her as a kid to make the timeline all square again.
- Seers: Madame Shyarly is a well known seeress, but know she has given up her career. Only to casually fortell the destruction of Fish-Man Island.
- Sibling Yin-Yang: A surprising one. Who would've guessed that such a nice lady (except for when she's mad) could be the younger sister of Arlong?
- Statuesque Stunner: She's very beautiful and also enormous compared to normal merpeople (though not to Shirahoshi's extent).
- The Ugly Guy's Hot Daughter: Or rather, The Ugly Arlong's Hot Sister. Somewhat justified in that you can't guess what offspring a Fish-man/merfolk would bear (and that she's just Arlong's half sister), but still.
- Threatening Shark: Downplayed, she is a very nice person. Just don't be rude with her.

Also known as the Kraken, a gigantic octopus that resides deep beneath the ocean. He first appears as an obstacle for the Straw Hats before they can reach Fish-Man Island, but Luffy Zoro and Sanji defeat him with ease. It's later revealed he works for the New Fish-Man Pirates due to complicated reasons. The Kraken gets his new name "Surume" from Luffy after being befriended by him following the battle.
- An Arm and a Leg: Zoro severs apart one of his tentacles like an apple. This is actually not a big deal, as Surume can simply regenerate them back.
- Badass Adorable: Surume is a fearsome kraken, able to sink entire ships with his tentcles nut, after Luffy tames him, his adorable side comes out.
- Combat Tentacles: His tentacles are his main "weapons". Surume has more tentacles than double the number of a normal octopi. At his size, the tentacles make Surume a dangerous enough threat that it takes people of Luffy, Zoro, and Sanji's caliber to deal him any notable harm, and even then it wouldn't last very long because of his regeneration.
- Cool Pet: After being tamed by Luffy, Surume shows to be a friendly and docile Kraken.
- Defeat Means Friendship: Surume doesn't side with the Straw Hats until being beaten into submission, and decides he's better off on their side after Having a tentacle sliced up and another one burnt.
- Funny Octopus: A gigantic, squishy octopus who is actually friendly and only worked under Hody by being threatened.
- Good All Along: While he appears to be a malicious monster, Surume is actually nice. The reason why he joins the New Fish-Man Pirates is because Hody threatens to kill his brothers if he doesn't obey him.
- HeelFace Turn: Originally works under the New Fish-Man Pirates, but switches sides when Luffy tames him.
- Kraken and Leviathan: The former. It is noted as a legendary creature whose brothers corpse will sell for a decent price if he doesnt obey Hodys orders.
- Non-Indicative Name: Surume actually refers to dried squid and not octopus. Justified since it's a name he receives from Luffy.
- Rapid-Fire Fisticuffs: Surume tends to fight equally-giant creatures with quick tentacles attack.
- Team Pet: Initially, Surume is an ally of the New Fish-Man Pirates, but only because Hody threatens to kill his brothers and sell their corpse, and the main animal on their side.
- Unskilled, but Strong: His "fighting style" consists of mainly crushing opponents or punching them with his tentacles, but his sheer strength and size make him a terrifying opponent.
New Fish-Man Pirates
Another group of Fish-man pirates hailing from Fish-Man Island and lurking within the Fish-Man district. They are led by Hordy Jones, the Great White Shark Fish-man. They are the main antagonists in the Fish-Man Island Arc.
Having an intense hatred for humans, the New Fish-Man Pirates become downright monstrous in their own enslavement of captured sailors and pirates, assassination and oppression against anyone who doesn't hate humans as much as they do, and plan to usurp the throne of Fish-Man Island to attend the Reverie and slaughter the kings of the surface.
Thecrew possesses many advantages, being Fish-men fighting at the bottom of the sea, and are 100,000 strong, with 70,000 Fish-men and 30,000 slaves. Moreover, their higher-ups use a special Energy Steroid to boost their strength. Nonetheless, they are easily decimated by the Straw Hats, freshly out of a two years long training.
The crew was successfully dismantled and its leaders imprisoned, rendered harmless and extremely old due to the overuse of steroids.
- Ascended Fanboy: The crew used to look up to Arlong and Fisher Tiger.
- Bad Boss: Unlike Arlong, the leaders of the New Fish-Man Pirates have no qualms about harming their own men.
- The Beastmaster: The Crew seems to employ several massive sea monsters, even Surume the Kraken.
- Berserk Button: They have such a rooted and irrational hatred for humans that they hate when Fish-men have a positive opinion on them, and go as far to burn the house of a Fish-man family that hosted a human.
- Cloud Cuckoo Lander: Ohh boy, where to start... Dosun's Verbal Tic changes depending on his strength, Zeo is trampled by his own underlings and yet dismiss the accident as if it didn't happened, Ikaros Much is scared shitless of fires (a friend of his came to close to the sun and burned) and on the top of his spears has moist-draining squids. Last but not least, when Hyouzou is drunk he slices anyone in his way.
- Curb-Stomp Battle: None of the officers really manage to land a hit on the Straw Hats save for some minor inconveniences and, at best, are just able to keep up with them. Once the SH stopped playing around however and broke out the finishers, it was pretty much over in an instant.
- Defiant to the End: Even after Hody's defeat they weren't willing to give up. Even after aging rapidly they still won't give up.
- Dramatically Missing the Point: Chapter 622 reveals that the crew was originally just a bunch of impressionable youths who were friends with each other, cheering when they heard of Fisher Tiger's exploits in Marejoia. They believed he did it to show the Fish-men's retribution to how they are treated by humans. While that's partly true, they also didn't get that Tiger actually freed the human slaves since he felt he couldn't just leave them in captivity, and was fighting oppression in general, not just the humans. Still, they then swore to dedicate themselves to violence towards humans wherever they find them when they grow up. Jones, in particular wanted to be Arlong's First Mate, even though Tiger often reprimanded Arlong for his brutality towards humans.
- Elite Mooks: The one-shot character Harisenbo, porcupinefish and leader of the Sea-Urchin Armor Spine Squad.
- Evil Old Folks: What chomping down on E.S. like it was candy did to them.
- Fantastic Drug: They seem to use E.S. (Energy Steroid) to boost their strength big-time.
- Fantastic Racism: They hate humans even more than Arlong, although they do employ a few. They tried to bring Luffy in, and they had at least Gyro as a unwilling member. Their Jolly Roger even has a decapitated human on it. A flashback went into detail about this, showing that the crew having grown up in the Fish-Man District, learned to hate humans from the residents there.
- Foreshadowing: Their version of the Sun Pirates emblem replaces the dot in the center with the image of a decapitated human. This hints at their Irrational Hatred as such an emblem wouldn't cover up a Celestial Dragon slave brand, meaning none of them ever had contact with a human.
- Inescapable Net: Hammond's weapon of choice is a net-shooting cannon. Not so inescapable to Robin, though.
- Irrational Hatred / Feeling Oppressed by Their Existence:Fukaboshi: What the hell did those humans do to you!!?
Jones: ... Nothing.
- Jerkass Knight Templar: While being as much of a monster as Arlong, they do genuinely seem to believe in a cause of hope for Fish-men than Arlong's passing rhetoric where money comes first over helping other Fish-men, but they are still massive assholes with little regard for humanity, their own kind when they thinks they betrayed them, or even their own crewmates.
- A Nazi by Any Other Name: A very intense hatred for humans largely due to the negative influence of the environment they were living in. Arlong as well as countless human hating Fish-men filled their heads with anti-human propogada, making them believe that it was their duty to deliver punishment to humans and human supporters. To really drive the point home, a part of their flashback reveals them burning down a house of a Fish-man who had donated blood to save a human while wearing black masks.
- Nice Hat: Daruma & Much's helmets.
- No Name Given: To the Fish-man to the right of Hammond during their introduction in the manga. He was named "Kasagon" in the anime.
- Normal Fish in a Tiny Pond: The officers are clearly more dangerous than anyone on Fish-Man Island, with Hyozou holding the title of strongest swordsman. They dream of conquering the world as soon as they 'reform' the island. Right after defeating the Neptune Army, they get clobbered by the Straw Hats very easily.
- Not So Different: They go on about being inherently superior to the 'lesser' race of humanity and take human pirates as slaves, just like the Celestial Dragons do. When Jimbei asks Robin to free those slaves, he remarks at his disgust of Hody and Co. "playing Celestial Dragon."
- Poisoned Weapons: The Deadly Poison Squad is composed by Fish-men armed with extremely venomous weapons.
- Power at a Price: The Energy Steroids work a lot like Gear Second.
- Punny Name: Many of them.
- Hammond is a Daggertooth Pike Conger Eel, the Japanese name of which is "hamo".
- So is his laugh style.
- Put on a Prison Bus: At the end of the Fish-Man Island arc, Neptune has Hody and his subordinates thrown in the palace prison.
- Quirky Miniboss Squad: Emphasis on "Quirky". Ikaros is pyrophobic, Zeo acts as if he plans everything, Dosun has a varying Verbal Tic depending on his power, and Daruma is an Ax-Crazy person who likes to threaten people with being eaten.
- Rapid Aging: All of them go through this when the Energy Steroids take effect.
- Red Shirt Army: After capturing the royal family they whip out an army of 70,000 Fish-men and 30,000 human pirates but Luffy halves their numbers with a shot of Haki.
- Slasher Smile: Well, most of them are sharks or eels, so it's kind of unavoidable. Except for Zeo, who has no visible mouth.
- Slave Liberation: After seeing the Straw Hats take down most of the Red Shirt Army and the easily handling the Quirky Miniboss Squad and the arrival of the Neptune Army taking down the weaker Fish-men, the slaves realized this is an ideal time to revolt and escape.
- Small Name, Big Ego: They talk big, and can somewhat back it up, but they're not much compared to a New World-ready pirate crew.
- Spikes of Villainy: The Sea-Urchin Armor Spine Squad is composed by spiked Fish-men wearing armors full of spikes.
- Stupid Evil:
- Their cause has no real substance as unlike Arlong, they don't have any experience to hate humans over. They were just told as kids to hate humans and grew up on that philosophy. Thus all their actions are just purely out of ignorance.
- Then there's the way they maintain their arrogance and believe they'll be able to defeat the Straw Hats, despite it obviously being a Curb-Stomp Battle.
- Sympathy for the Devil: In a general sense, their existence served to highlight exactly how bad conditions in the Fish-Man District have become to the royal family. After their defeat, steps are taken to address the social and economic problems that the Fish-men have been suffering rather than just punishing them for their attempted rebellion. The officers having aged into feeble old men also made them pitiable and Neptune mentioned that he would reconsider their sentences.
- Take Up My Sword: They seem to have embraced Tiger's "negative" politics and Arlong's.
- Tattooed Crook:
- All of them have modified "Mark of the Sun" tattos (their version has a decapitated human crossed off) of the original Fish-Man Pirates on them, and some have Arlong's Jolly Roger, too.
- Some minor Foreshadowing there considering their "mark of the sun" tattoos have blank spaces in the center, which for the originals hid the slave brands that some of the crew had. This absence indicates none of the New Fish-Man Pirates were slaves, hinting at their Irrational Hatred.
- "The Reason You Suck" Speech: Delivered by Hody, Hyozou, and Decken to Hatchan.
- Threatening Shark: Four of them are shark-type Fish-men:
- Hody Jones the Great White.
- Dosun, the Hammerhead.
- Zeo, the Japanese Wobblegong/Carpet Shark. (Although he looks more like Zoidberg).
- Daruma the Cookiecutter.
- Verbal Tic:
- Dosun seems to inject their names into their sentences.
- And Hammond's laugh of "Hamohamohamo!".
- Chapter 630 revealed that Dosun's tics depend on his current power level.
- Villain Team-Up: With the Flying Dutchman Pirates.
- We Have Reserves: The crew's attitude towards their human slaves. Seen with their weapon "Slave Tank" (a tank-like structure carried around by a bunch of chained slaves).
- The Worf Effect: The New Fish-Man Pirates in general seem to be this, as their main purpose really is to show how much the Straw Hat crew has improved over the time skip.
- You Have Outlived Your Usefulness: To Hachi.
- Younger Than They Look:
- We saw young Hachi back in Chapter 0, which was 20 + years ago, and Jones mentions he's his senior, so he probably around 20-21ish, despite looking older than even Arlong.
- Even so, in actuality, Hatchan and Jones are really roughly the same age, though Hatchan might be slightly older. Jones was 15 when Fisher Tiger raided Marejoia, so that would make him 30.
- Taken Up to Eleven in Chapter 650. The drugs the leaders have been using to fight have taken their toll, causing them to become withered old geezers.

A Great White Shark Fish-man, the captain of the New Fish-Man Pirates and a former soldier of the Neptune army, Hody Jones is an admirer of Arlong and strongly believes in his ideals. He leads the assault on the Ryugu Palace in order to take over the kingdom while his underlings create chaos elsewhere on the Island.
- A Nazi by Any Other Name: Not a fan of humans? Check. Considers his race to be the supreme one? Check. Thinks he's saving his country by starting a reign of oppression? Check.
- His joining of Neptune's Army purely to learn combat skills possibly alludes to how members of the Ku Klux Klan and Neo Nazis would do the same in the 20th century; they would join the US military, learn how to fight and use weapons, and then terrorize the populace.
- Arc Villain: Alongside Decken, Hody is the main antagonist of the Fish-Man Island arc, but he holds a greater position and is a major threat to the island.
- Armor-Piercing Response: Fukaboshi inquires him on what kind of atrocity the humans have done to him that made him loathe humans so much. Hody's answer ("Nothing") makes Fukaboshi realize that the kingdom has neglected the Fish-Man District (where Hody was raised in) for so long and is ignorant on what kind of ideas going on around the place that turned Hody into the man he is now.
- Ascended Fanboy: Toward Arlong.
- Ax-Crazy: This guy is so batshit, he's willing to destroy Fish-Man Island, and rule over whoever survives as part of his "new era" of Fish-man pride, all in the name of his revenge against humans... who didn't even do anything to him personally. He just hates them because he was taught to.
- Bad Boss: Jones is the exact opposite of Arlong in this respect. Whereas Arlong was upset by Luffy using one of his men as a shield, Jones is perfectly fine with doing the same to his men.
- Outright confirmed in Chapter 627. By Hachi no less.
- To the point that he tries to kill Vander Decken himself when he finds out his plans.
- Big Bad Duumvirate: Hody aligns with Vander Decken IX as they plan to Overthrow King Neptune, however, their combined strength isn't enough to even worn out Luffy.
- The Caligula: As he tries to become the new king of Fish-Man Island, one of his projects is to execute, one by one, all those who had signed Queen Otohime's petition for migration. Seeing on how effective her rallies were, he's potentially willing to kill thousands (if not more) of his own subjects.
- Then there's his "vision" for representing Fish-Man Island before Reverie: by brutally killing all the members present. And that's likely before he executes all those who signed Otohime's petition.
- Call-Back: After taking the E.S., Jones's eyes become "lizard-like" just like Arlong's did.
- During the underwater battle in Chapter 641, he uses the same teeth trick used by Arlong (leaving his teeth on Luffy and growing new ones in seconds) and later gets his Kirisame blade broken by Luffy.
- Clipped-Wing Angel: Even in his ultra-badass new form, Luffy mopped the floor with him. He got in two solid bites, and those only happened because Luffy was fighting underwater, which his Devil Fruit power did not help, and in the second, he strained himself trying to beat Noah into splinters. Furthermore, he's defeated even before his subordinates, making it a unique case so far in the manga.
- Not to mention his overconsumption of E.S. made him age into an old man. You can't get more clipped than that.
- Curb-Stomp Battle: Twice. The first time was with Zoro, and his resulting injuries were so bad that he developed a dependency on energy steroids just to keep going. The second time was with Luffy, who ends him for good (along with an overdose turning him into an old man).
- Deadly Upgrade: When he takes E.S., and in Chapter 630 he underwent a massive, nightmarish one.
- Descent into Addiction: He takes increasingly dangerous amounts of Energy Steroids over the course of the arc, which takes its toll on him after he's defeated.
- Determinator: Jones knows his drug abuse is rapidly shaving his life off, but he will bring the Fish-men to the top of the world, even if it kills him.
- If nothing else can be said about his performance against Luffy, he took a lot of punishment before he finally stayed down. Luffy postulates that his toughness alone would earn him at least a 100,000,000 Berry bounty.
- Do Not Adjust Your Set: Jones broadcasted on TV an announcement that from now on, he's taking control of Fish-Man Island, that there'll be a public execution for the King, as well the drifting Straw Hats. Oh, and that he'll execute every one of the citizens who signed the late Queen Otohime's petition to be recognized by the surface.
- Evil Laugh: "Jahahahaha". Notably near-identical to his idol Arlong's laugh.
- Evil Is Petty: As it turns out, humans never did anything to him personally. He just hates them because it's what he was raised to believe.
- Evil Sounds Deep: He's definitely evil, and has a deep voice to go along with it.
- Fantastic Drug: Jones uses Energy Steroids to boost his strength and as a (very temporary) pain reliever for the wounds Zoro inflicted on him.
- Fantastic Racism: His hatred of humans is even more passionate than Arlong's, although the New Fish-Men Pirates do employ a few. They tried to bring Luffy in, and they had at least a few unwilling human members (though it's pretty doubtful Hody would've "hired" the Straw Hats anyway, considering Luffy was the one to beat his idol). Their Jolly Roger even has a decapitated human on it. Later, his hatred is shown in greater detail when one of his crew members states that he kills any Fish-man with human-transfered blood in them since they're now "dirtied." The truth is that he doesn't even have a Freudian Excuse to justify his racism, unlike Arlong; he was entirely raised on anti-human sentiments through most of his childhood and teenage years, until he breathed what he learned, without direct, traumatizing exposure to actual humans to color his views.
- Fat Bastard: He starts out fairly plump, and after his Energy Steroid overdose makes his muscles more prominent, he still retains an overall large frame. His final transformation buffs him up considerably though and then he becomes a frail, old Fish-man.
- Feeling Oppressed by Their Existence: What seemingly was a Freudian Excuse was actually not anything of the sort; he simply does all this because he really hates humans.
- Freudian Excuse: ZigZagged. The humans never did anything to him, personally, unlike Arlong, Fisher Tiger, etc. He grew up in a place of systemic and ingrained racism that still warped his morals. It was enough he'll gladly wipe humans all out. The fact he doesn't have such a direct trauma is treated as rather shocking. At the very most, he was a victim of isolation — with no actual experience with the outside world to temper his views, he unquestioningly bought into all the anti-human rhetoric and became heavily radicalized.Fukaboshi: What happened to you? Did humans torture you!? Did they kill your crewmates or someone you loved!? What did you go through in the past!? ANSWER ME HODY! WHAT DID HUMANS DO TO YOU!?Hody Jones: Nothing.
- Fur and Loathing: Jones has what looks to be a dead, fluffy dog wrapped around his neck.
- Genocide from the Inside: It's not just humans and Merfolk; any Fish-man who disagrees with him is on his hit list, too, which is implied to be the vast majority of them.
- Gonk: Not normally, but after his One-Winged Angel, he slowly starts growing more and more grotesque as the arc goes on. In particular, during his fight with Luffy he eats steroids in between his beatdown to keep himself conscious, and his muscles grow larger and larger until he's a bulging freak that's twice the size of co-villain Vander Decken, whom he was formerly shorter than. And then, his face and jaw become enlarged and swollen until he's truly frightening in appearance.
- Hate Sink: Hody is a racist and extremist Fish-man, similar to Arlong, but lacks Arlong's redeeming qualities like caring for his own crewmates or experiencing the humans' treatment of Fish-men to at least justify his racism. Hody himself saying that humans never really did anything to him just made his tirade seem stupid and shallow, when many Fish-men were victims of racism and slavery.
- Hoist by His Own Petard: A triple subversion. Eventually, Hody takes too many Energy Steroids, trying to use them as stimulants to keep himself awake despite the nasty wound he has. It ends up causing all of his fat cells and muscle tissue to burn from the inside... but then all that internal wear and tear made him stronger... only for a little while, because the Energy Steroids were made from the National Treasure of Fish-Man Island — as in, the treasure that can turn someone older like in the Japanese folktale "Urashima Tarō". In the end, the abuse of Energy Steroids caused the bodies of Hody and anyone who took it to break down and age rapidly to the point of becoming frail old men.
- Hulk Out: He was already pretty large beforehand. After overdosing on the E.S., he dwarfs even Fukaboshi and Vander Decken.
- Hypocrite: Despite his utter disgust at the World Nobles, his actions (such as forcing people to be his slaves and believing his power allows him to do what ever he wants, and how he views himself born superior) ironically make him the same as them. Jimbei even lampshaded the similarities by referring to Hody's actions as "playing Celestial Dragon."
- I Knew It!: An in-universe example is that Shirahoshi was aware of the true identity of her mother's killer.
- Ignorant of Their Own Ignorance: The only excuse he had for believing that a mere army of 70,000 pill-popping underlings and 30,000 slaves stood a chance against the World Government. The Straw Hats disabuse him of this notion. Thoroughly.
- Implacable Man: If nothing else he's rather more enduring than your average Starter Villain, to the point that Luffy was actually surprised at how many Haki-infused punches he could take. Justified, he had taken a lot of Energy Steroids before that fight.
- Improbable Weapon User: Kirisame, a massive curved blade that he can attach to his dorsal fin.
- Jerkass: While he's just as much of a Fantastic Racist as Arlong, Jones does seem to genuinely believe in the Fish-man cause, contrasting Arlong's passing rhetoric of money first and race second, and having had no experience with the outside world. He's still a massive asshole with no regard for humanity and little for his own kind, though. He barely even cares about his crew. This is later averted however as his cause has no reason to it. While Arlong was already a bigot against humans, the death of Fisher Tiger drove him to his actions, and was also why he was against hurting his own kind. Hody however was simply told to hate humans and he just grew up on this philosophy with none of the experience. Hence why he's so willing to kill his own men and throw himself into reckless actions with disregard for his own life.
- Kick the Dog: Remember how peeved Arlong got when Luffy used one of his crew members as a shield? Hody has no such particular reservations.
- Knight Templar: He has nothing but hatred for humans no matter what, and if any merfolk or Fish-men even think of peace with humans, he'll kill them, too. In fact, he personally killed Shirahoshi's mother for preaching human-Fish-man coexistence.
- Locked into Strangeness: His hair becomes white after overdosing on Energy Steroids. It's actually a very clever case of Foreshadowing; his hair didn't turn white because it was just a part of this badass transformation, it was actually the first sign that he was aging.
- Made of Iron: After his One-Winged Angel, he was able to recover from several hard Haki-infused attacks from Luffy.
- Most notable at the end, when he gets punched so hard, it nearly disembowels him... but he not only survives that, he doesn't seem to suffer any after-effects of the blow.
- Manipulative Bastard: He misdirected the entire Fish-Man Island into believing a human killed Otohime, Shirahoshi's mother to cover up the horrible truth: it was he, a Fish-man, who killed her.
- Making a Splash: Being a Fish-man, this is obvious. One of his attacks involves a volley of arrow-like waterdrops.
- Jimbei stated that he knows Fish-Man Karate, but Hody's not nearly as good as him.
- Meaningful Name: Jones is also slang for heroin, or drug addiction. Suits a guy who uses steroid pills, isn't it?
- Also, "Hody" in Japanese sounds like "Hoji". The Japanese name for Great White Shark is Hojirozame (頬白鮫).
- Furthermore, most of his attacks are a Hurricane of Puns involving sharks.
- His name is also derived from Davy Jones. One could indeed call him a devil of the sea.
- Meet the New Boss: Picture if Arlong was a lot tougher, had Blackbeard's physique, lacked moral standings, and did a lot of drugs. That's Jones, literally an amoral Arlong On Steroids. Even his laugh is similar to Arlong's. Justified since Jones is a fan of Arlong.
- He's a composite of villains' characteristics from the first quarter of the series. He's got Arlong's race, powerset and bigotry, Eneru's Social Darwinism and ship-based island destruction fetish, Krieg's massive army and proclivity towards shortsighted acts of cruelty, Buggy's general ignorance coupled with just enough knowledge to make him dangerously overconfident, Kuro's underhandedness and complete and utter lack of regard for the lives of his men, Wapol's obesity, reliance on ingesting things to be a threat, and completely one-sided fight against Luffy that ends with one final desperate (and failed) bid to gain an advantage, Crocodile's plan (infiltrate country's security, kill king, take over country, get control of/kill one of the Ancient Weapons) and minions (a digging guy, a dumb dude with a big club, a traitorous Dragon with an Agenda who tries to kill him with a knife, a clown who thinks he's smarter and more sophisticated than other people). Which is all to show that the Straw Hats have exceeded those previous challenges and are ready for the New World.
- Moral Myopia: He deems Decken a traitor to their alliance for attempting to drop Noah on Fish-Man Island while the New Fish-Man Pirates are on it... but then he decides to go with the plan by killing Decken (who survives, but is later knocked out by a mere rock), to drop Noah on Fish-Man Island while the New Fish-Man Pirates are on it. Apparently, the only issue was his life being at risk, and he simply states that he can replace his crew with human slaves.
- Nice Hat: He's got a newsboy cap. He loses it when he OD's on Energy Steroids.
- Nightmare Face: One that combines Red Eyes, Take Warning and a very toothy Slasher Smile, during the part where he commands Noah to fall onto Fish-Man Island. The image was later given the honor of being on One Piece's Nightmare Fuel page.
- No-Holds-Barred Beatdown: No matter how much of a Determinator he is, he still receives these left and right from Luffy.
- Normal Fish in a Tiny Pond: His greatest flaw is his lack of experience. Hody, unlike Arlong, has never been to the surface; hence, he is completely unaware of how out of his depth he is. It's because of this that he got the idea that a force of 100,000 pill-popping underlings had a chance against the World Government, when they didn't even have a chance against one stinkin' pirate crew (albeit, a very powerful pirate crew). Vice-Admirals would've decimated them in minutes, while an admiral would've outright annihilated them.
- Now That's Using Your Teeth!: As befitting for a white shark Fish-man, Jones, hopped up on Energy Steroids, can destroy an entire ship with his teeth.
- Oh, Crap!: When he sees Luffy take down half his army with a burst of Conquerer's Haki, Hody remains shocked and realizes how much he underestimated the Straw Hat Pirates.
- One-Winged Angel: The Energy Steroid overdose that nearly killed him... actually made him really powerful.
- Painful Transformation: What he went through to take on his One-Winged Angel form.
- Politically Incorrect Villain: He's all of Arlong's bad traits magnified Up to Eleven and minus his very few redeeming factors. His racism against humans, unlike Arlong's, were entirely based on what he was taught his entire life, rather than actual experience. When Fukaboshi calls him out on his atrocious behavior and asks for a reason for his hatred, Hody simply replies, "Nothing."
- Power at a Price: The Energy Steroid does indeed increase one's strength and power but literally does take away the user's life-force by accelerating their age. This is why Hody's hair turned white as by that point the drugs had heightened him to the peak of his health. By the time Luffy beats him, they've aged Hody into his twilight years, too old and frail to be of any threat anymore. And the kicker, the dope never even realized it.
- Power-Up Letdown: Hody chugs down a lot of Energy Steroids and become a true force of nature, however, not only it isn't close enough to beat Luffy, but has the side effect of turning him into a wrinckled old man after a short while.
- The Power of Hate: Despite not having experienced any mistreatment by humans, this what motivates Jones: blind, unreasoning hate towards humans which he extends to any Fish-men who want to make peace with humans.
- Prongs of Poseidon: His weapon seems to be a large black trident from his days in the Neptune Army. He uses it again later in the story. On Vander Decken.
- Punny Name: Jones got attacks that he named "Soshark" (pun on Soshaku, meaning eating roughly) and "Yabuzame" (a kind of horse archery). Not to mention his name is a pun on Hojirozame, i.e Great White Shark, of which he's one.
- Red Eyes, Take Warning: His eyes were actually red to begin with, but the energy steroids extend the red from his irises to his sclerae.
- Scary Teeth: Comes with being a Great White shark Fish-man, and a Big Bad of an arc, to boot. Even after the fairly one-sided battle with Luffy, the one clean bite he got in (he inflicts some more injuries in the anime) nearly killed Luffy from blood loss.
- "Shaggy Dog" Story: His entire plan involved using the ES to boost his power in order to make Fish-Man Island his kingdom, kill every king in the World alliance and eventually take over a world filled with figures who are unfathomably stronger than him as Luffy, a rookie, so obviously showed. Plus, even if he did manage to destroy Fish-Man Island along with the Straw-hats, the "ES" turns out to a national treasure that ages in an extreme rate as his fate after defeat showed, meaning he would be too weak to do anything at all.
- Shaping Your Attacks: Can shoot shark-shaped bullets with his Murasame attack.
- Shark Man: Hody is a Great White, known to be the largest carnivorous shark, Fish-man and he's a strong and vicious person. But is not enough for a stronger Luffy who easily stomps on him.
- Shoot the Messenger: When Shirley informs him of her visions of Luffy destroying the island, meaning his takeover will be entirely pointless. He, of course, gets pissed and hits her with a water shot.
- Shown Their Work: When Jones bites something or opens his mouth, his teeth look exactly like the ones of a real White Shark (complete with the exposed gum, for example).
- Slasher Smile: Being a shark, it's inevitable.
- Small Name, Big Ego: He might have been a good opponent pre-Time Skip, but he's just out of his league against the Straw Hats now after they each underwent their own Training from Hell, and is completely unaware of it. He also seems to have no comprehension of just how powerful the people he would be fighting on the surface are.
- Smug Snake: Thinks he's a big deal (which he kind of is) and an invincible, unfuckwithable offensive force. The latter is what ultimately resulted in the completely hopeless, one-sided "fight" and subsequent ass-whooping at the hands of a pissed-off Luffy after he lost very badly to Zoro and almost died.
- Sorting Algorithm of Evil: To a truly ridiculous degree. Caesar Clown at least got in a few good shots against Luffy, while Jones managed to get in absolutely nothing except a few strikes that Luffy barely even noticed that did not even come close to offsetting the lengthy and truly savage beating that Luffy handed him after Zoro had very nearly killed him in an even more one-sided fight. Pre-timeskip, he probably could have given Luffy one hell of a fight. Post-timeskip, he exists to do nothing except demonstrate how much the Straw Hats have grown in power; it's clear that most, if not all of them could have beaten him fairly easily.
- Spell My Name with an "S": The Funimation dub calls him "Hordy."
- Spikes of Villainy: Jones has some jutting out of his left wrist.
- Starter Villain: For the Second Half of the series. For all those muscles, beat-downs against regular humans, One-Winged Angel transformations, and supposed badassery, Hody proves to be absolutely no match for a new and improved Luffy at all. In the end, the stats for their fight are as follows: For Luffy, a kick to the gut that sends Hody flying several yards away into a wall, a kick to the face that draws the first blood of the fight, another kick to the face that drives him into the ground, a Haki enhanced punch to the gut (which again sends him flying into a wall), a clawed hand to the shoulder that tears into him, another punch to the face that sends him flying into a wall, yet another punch (Haki imbued this time) that sends him flying immediately after that one, a "Gum Gum Red Hawk" that bursts a hole through his back and sends him flying-yet again- several hundred feet away into a wall, and finally, a Giant, Haki imbued fist that knocks him several degrees into unconsciousness. Into a wall. For Hody: Several missed "water shots", a failed spin kick that led to the aforementioned kicking of him into the ground, one punch landed to the head that didn't affect Luffy at all due to his Rubber Body, and one lucky bite on the shoulder he got in just as Luffy punched him into a wall for the umpteenth time. Wow. You've got to admit though, he is pretty durable for standing up to all that before finally collapsing into a bruised, broken, bloody mess. And he's pretty great at getting sent flying into walls.
- Stout Strength: Hody has a stout and chubby body but is also much stronger than the average Fish-men, who is already ten times stronger the average huma. After taking Energy Steroids, however, his body becomes ripped.
- Stupid Evil: Hody is an incredibly racist Fish-man, and said devotion toward the Fish-Man race leads to him making illogical decisions. He only hates humans because of the negative environment he grew up in. So, all his actions are just generally out of ignorance from what he was taught. Not only that, but he never realizes that what he planned wouldn't be likely to go smooth like he thinks, and he also did many things that are detrimental to his plans such as deciding to let Fish-Man Island get crushed by Noah.
- Then there is the way he constantly eats the energy steroids without thinking they might have side effects such as say turning him into an old man
- Tattooed Crook: He's got a whole host of tattoos, namely his New Fish-Man Pirates on his abdomen and a bunch of Arlong's on his arm but no Sun Pirate tattoo, showing that he's a fraud and has no leg to stand on when it comes to the "humans have wronged us" talking point.
- Take Over the World: He has much grander plans than his idol Arlong ever did. After he kills everyone in Reverie, and those who signed Otohime's petition, he plans to enslave all of humanity. And then become Pirate King. Luffy was not amused at the last one.
- Took a Level in Badass: Overdosing on Energy Steroids has made him significantly stronger. However he's still too weak to fight Luffy on dry land, but he manages to get an advantage by fighting underwater, where he can move better. Which didn't help a damn thing because Luffy still beat the tar out of him nevertheless.
- The Unfettered: There is no length that he won't go to in the name of Fish-man supremacy.
- Truth in Television: His extreme hatred of humans for no reason besides his environment is actually how most real-world racists/sexists/bigots gain their views. Without counterpoints people tend to accept what they are told from a young age as true.
- Tyke Bomb: A Fish-man orphan and his friends raised almost solely underneath the teachings of Fantastic Racism taken to its most extreme.
- Unskilled, but Strong: After overdosing on the Energy Steroids, he was strong enough to send a drop of water flying across the island. However, his Fish-Man Karate was at an amateur level compared to Jimbei, who was quick to point this out. Now thanks to being reduced to a frail old man due to his abuse of the Energy Steroids, he doesn't even have his natural strength anymore.
- Viler New Villain: He makes Arlong look like a saint by comparison. Arlong still has some degree of compassion towards his fellow Fish-men and cares for them as individuals, Jones is more obsessed with Fish-man supremacy as an idea and is willing to kill his own people. Arlong merely enslaves humans to get profit and only kills them if they fail to pay him, Jones' brand of enslavement is worse as he tends to send them to their deaths — and for those he doesn't enslave, he'll assault (and kill) with glee.
- Villainous Breakdown: His smug composure goes very quickly after seeing how strong Luffy is. Eventually he decides to pull a Colony Drop by dropping Noah on top of Fish-Man Island, but fortunately Luffy and friends (and the Sea Kings) were able to stop it before anyone was killed.
- Virtue Is Weakness: He laughs at Princess Shirahoshi for not hating him since she already knew he killed her mother, because that's what her mother have wanted and sees his fellow Fish-men and Merfolk who wanted to make peace with the humans as traitors.
- Visionary Villain: If a somewhat warped one; he believes in Fish-man supremacy over humans, and is willing to kill anyone who sides with them. But unlike Arlong, who had genuine reason and experience to justify his crappy treatment of Nami's village, Hody was fed racist teachings until he embodied them. In truth, he hates humans because that's what he was taught to believe.
- Warmup Boss: Of the post-timeskip, he's the first major villain Luffy fought (Demalo Black fails to count as "major"). He has the buildup as an unstoppable Great White Shark Fish-man with steroids, but he still yields to Zoro and then Luffy to showcase their growth and new abilities.
- Wham Line: Immediately after being publicly called out by Fukaboshi and asked what exactly humans have done to Hody to make him hate them so much, he drops this atomic nuke of a line that reveals he was really only acting on what he was taught:"Nothing."
- With My Hands Tied: Jones destroys an entire crew using just his teeth to show off and tell them they have no chance.
- Wound That Will Not Heal: His fight with Zoro left him a wound so severe that eating energy steroids only provides temporary relief.
- The Worf Effect: Early on the Fish-Man Island arc, Zoro took him out. With one slash. Underwater. The wound was so bad that Hody had been overdosing on energy steroids ever since. Which is why it was no surprise that even when Luffy was stuck underwater, in a bubble, Hody still got his ass kicked. This is to show that while Hody may have been a good opponent pre-Time Skip, he is nothing compared to a New World-ready crew.
- Younger Than They Look: Hody's eventual fate for overdosing on Energy steroids is turning into a really old guy — like, only skin and bones and incredibly frail type.

A hammerhead shark Fish-man and one of the officers of the New Fish-Man Pirates.
- Calling Your Attacks: While Dosun's attacks are all simple hammer hits, he shouts a different name for each according the strength he puts in them.
- Drop the Hammer: Dosun hefts around a gigantic hammer as his primary weapon, fittingly for a hammerhead shark Fish-man.
- Dub Name Change: Dosun is renamed Sbam in the Italian translation, in order to keep his Punny Name.
- Dumb Muscle: Dosun is strong enough to carry a big hammer around but does not seem to be particularly bright. Even his design emphasize his strong arms but gives him a small head compared to the rest of the body.
- Gonk: Thanks to being a hammerhead shark Fish-man he has an unattractively-shaped face.
- Punny Name: "Dosun" is also the Japanese onomatopeia for a heavy thud, like an hammer, his weapon of choice, hitting something.
- Stout Strength: Dosun appears to be a bit doughy, as well as very strong.
- Top-Heavy Guy: Dosun's design emphasizes his strong arms, almost as wide as his torso, while his legs are very skinny, showing that he attacks using his upper body since he wields a giant hammer.
- Verbal Tic: Dosun has a whole lot of them, all of them depending on how strong he's feeling at the moment, complete with more emphatic and louder deliveries. "Fosun" (when aged by the E.S) → Pikon → Kotsun → Potsun → Posun → Tosun → Dosun (normal level) → Dokan → Bokan → Zugan → Bagon → Gyaban → Gogyan → Dogyan → Bagyan → Gadon → Megagon — Dubagegagon — zugragugon — byorikogon. For the most part, they're onomatopoeia for crashing noises such as thuds and explosions in Japanese, with the upper echelon of power being gibberish for the most part.
- Visual Pun: Dosun is an hammerhead type Fish-man and as a weapon he uses a literal hammer.
"Aristocrat of the Fish-man District" Zeo
Voiced by: Shintarō Asanuma (JP), Nazeeh Tarsha (EN)
Debut: Chapter 611 (Manga), Episode 530 (Anime)
An officer of the New Fish-Man Pirates and Japanese wobbegong Fish-man.
- Chain Pain: Zeo's main weapon is a chain with weights on each end.
- Chameleon Camouflage: Zeo has natural camouflage abilities like a chameleon, by nature of being a wobbegong Fish-man.
- The Comically Serious: He acts calm and calculating, even as he tries to downplay something bad happening to him as part of his plans, with utter seriousness.
- Dual Wielding: In Chapter 642, Zeo is seen flailing two chains at once against Brook. Though in the same scene in the anime, he uses only one chain.
- Hidden Depths: You would never guess for a minute that Zeo is a skilled chemist (in making medicine at least), as Hody put him in charge of replicating and mass-producing the Energy Steroids.
- I Meant to Do That: Zeo does this a lot, such as when Brook stepped on his head he said "I'm headbutting your foot".
- Almost falls into I Reject Your Reality. Zeo is incapable of accepting that bad things happen to him, or that what he wants and what happens vary; he gets trampled by his henchmen and acts like nothing happened. Makes a Badass Boast to the Straw Hats only to be ignored, so he claims he was talking quietly.
- His "Body Sword Crush" and "Super Sole Headbutt" techniques are actually just him getting stabbed by Brook and getting accidentally stepped on respectively, with him claiming that those techniques will wreck the attacker.
- Age rapidly into an old man due to overusing Energy Steroids? He claims he grew old on purpose.
- No Mouth: At least no visible mouth.
- Punny Name: Zeo is the anagram of Ooze, (the japanese for Carpet Shark).

- The Napoleon: Daruma is very small compared to everybody else, probably not much bigger than the Brain point Chopper, and is very aggressive. Subvered in that he later appears to be actually almost as big as an average Fish-man or human, it's just that the other officers are freakin' huge.
- Now That's Using Your Teeth!: Daruma can destroy rock and concrete, and his snacks are composed of giant fish's bones.
- Punny Name: Daruma comes from the Japanese name of the japanese name of the Cookiecutter shark, (Darumazame).

A giant squid Fish-man and officer of the New Fish-Man Pirates. Ikaros doesn't care for his subordinates and impales them for fimsly reasons, although he shows some affection for his fellow officers and Hody, presumably because they grew up together.

In combat, he wields eight spears, one for each arm, with actual squids on top, but can also use his ink-split or his pointy head.
- Beard of Evil: Ikaros is part of a group of Fish-man supremacists and has a long, dark beard.
- Berserk Button: Ikaros hates even the reference fried squid, because his friend Daidalos, a giant squid, deydrated for being too close to the sun. He also has pyrophobia because of it and istinctively curls himself backwards at the sight of flames.
- Disproportionate Retribution: Ikaros debuts by sucking the moisture out of a mook, then flattening his dried-up body with several palm strikes, all for unknowingly setting off his fear of fire, and after the mook had already apologized.
- Dual Wielding: He can wield eight spears due to him being a Giant Squid.
- Even Evil Has Loved Ones: Ikaros is as ruthless as the other officers of the New Fish-Man Pirates, but he genuinely cared for his friend Daidalos, a giant squid, and was so traumatized by him drying up under the sun, that he developed pyrophobia as a result.
- Furry Reminder: Ikaros is a squid Fish-man with the habit of curling up backwards whenever he sees fire or gets shocked, in reference to dried squids.
- Giant Squid: Ikaros is a Giant Squid Fish-man. And is a huge, nasty-looking fellow with eight spears.
- Icarus Allusion: Aside from his name being a punny combination of "Icarus" and "Ika" (Japanese for "squid"), Ikarus's fear of fire originates from the death of Daidalos, his friend, who dried up after getting too close to the sun, just like Icarus died after flying too close to the sun and melting his wax wings.
- Me's a Crowd: Ikaros can make clones out of ink.
- Multi-Armed and Dangerous: Comes with being a Giant Squid Fish-man. Ikaros has ten limbs, eight of which are arms and each of them carry a long spear.
- Nice Hat: Ikaros wears a helmet which hides his pointy squid-like head. He removes it when he uses his pointy head to attack.
- One-Handed Zweihänder: Ikaros' spears are huge, but he wields and use them with one hand each, allowing him to use a total of eight spears.
- Primal Fear: Ikaros is afraid of fire because his friend died of drehydration after getting too close to the sun. As a result, whenever he sees flames, Ikaros curls up backwards, just like a dried up squid.
- Punny Name: His name is a combination of "Icaros" and "Ika" (which means "squid" in Japanese).
- Super Spit: Being a squid Fish-man, Ikaros can spit ink at will from his mouth.
- Spell My Name with an "S": His surname can be traslated as Muhhi or Much.
- Use Your Head: Ikaros's Light Bright Spear attack consists of using his pointy head, which glows, to pierce his enemies. He uses it against Franky without landing the hit.
- Verbal Tic: Ikaros tends to end sentences with his surname.
- X on a Stick: Ikaros's spears don't have blades but a squid at the end of each tip, which can absorb the moisture from living beings.

Debut: Chapter 607 (Manga), Episode 527 (Anime)
A poisonous blue-ringed octopus merman known as the best swordsman on Fish-Man Island, and a mercenary working as the New Fish-Man Pirates' assassin.
- Chekhov's Gunman: Way back in Chapter 84, Hatchi mentions that he's the second-strongest swordsman from Fish-Man Island. More than four hundred chapters later, it's revealed the strongest swordsman is Hyouzou, and there is quite a difference of strength.
- Drunken Master: However when he gets too much drunk he attacks anyone.
- Dual Wielding: Hyouzou can wield a couple other swords with his tentacle-legs, too.
- Funnel-Mouthed Cephalopod: Being an octopus merman, aside of an octopus-lower body, Hyozou has a funnel-like mouth.
- Gonk: He has a flat face and large mouth that protrudes out from his face.
- Locked into Strangeness: Like Hody, Hyouzou's abuse of E.S. has caused his hair to turn completely white, as well as buffing him up signficantly. Later he's reduced to an old man.
- Multi-Armed and Dangerous: He is multi-legged and quite dangerous.
- Normal Fish in a Tiny Pond: Zoro essentially calls Hyouzou this after easily defeating him (his exact words were "frog in a well", almost mimicking Mihawk's words towards him Pre-Time Skip).
- Not-So-Harmless Villain: When Hyouzou was first introduced, he had no intro box or dialogue, as both were given to the more aggressive Hammond. After their tussle with Luffy, Hyouzou blocked a Gear 2nd strike without being harmed, poisoned Luffy and was able to carry of Hammond and the un-named Lionfish member without any problems at all. This is subverted later on when Zoro easily defeats him, even while he's on steroids.
- Oh, Crap!: Hyouzou, after noticing that Zoro has just bisected all his swords in half just by parrying.
- Only in It for the Money: Hyouzou doesn't really seem to care about Jones' dream, and follows him only for money. If Arlong paid better, he admitted he would have gone with him to East Blue.
- Our Mermaids Are Different: An octopus merman, and the only villainous Merperson seen yet.
- Overly Narrow Superlative: He prides himself on being the best swordsman on Fish-Man Island. He is genuinely skilled, but when up against the disciple of the best in the world, he might as well be a frog in the well.
- Poisoned Weapons: He's able to coat his swords in his blue ring octopus venom.
- Poisonous Person: A blue ring octopus merman, which is an extremely venomous animal. If Luffy didn't get his Acquired Poison Immunity from Magellan, he would have killed Luffy.
- Spell My Name with an "S": Hyozou has been spelled as Hyouzou or Hyozo.
- The Worf Effect: Hyped and acclaimed as the strongest and most dangerous swordsman on Fish-Man Island, has his sword cut in half by Zoro, and totally fails to impress him. Even after taking steroids, mind you.
Flying Dutchman Pirates
A band of Pirates that sail around the area near Fish-Man Island, their Captain is Vander Decken IX, a Japanese Bullhead Shark Fish-man. They sail on the titular ship, a mysterious ship said to be cursed by the gods and forced to roam the depths of the ocean which is actually just a decrepit old ship that got Shrouded in Myth & inaccuracies. Vander Decken is wanted by the Neptune Army for his harassments toward the beautiful Mermaid Princess Shirahoshi. Recently he had allied himself with Hody Jones to take over Ryugu Kingdom, but toward the end of the battle, Hody seemingly killed Decken.
- The Beastmaster: Not as much as Jones's crew, but they at least have a giant Anglerfish alone to help them.
- Gonk: Wadatsumi has a nut-shaped head and goatee, and he's also disproportionately built, being very wide.
- HeelFace Turn: Wadatsumi ends up joining Jimbei's crew after getting exiled from Fish-Man Island.
- Ghost Ship: The Flying Dutchman, in actuality, it's just an old, beat-up but still normal ship.
- Legacy Character: The Vander Decken in the myths is actually the Grandfather of the current Captain.
- Meaningful Name: Vander Decken from Van Der Decken, legendary captain of the Flying Dutchman. Wadatsumi is also the name of a Japanese Sea God, born when Izanagi washed himself after his trip to hell.
- Shrouded in Myth: From them having a Ghost Ship to their captain Vander Decken being a very old person.
- Team Pet: Ankoro, a giant Anglerfish.
- Villain Team-Up: With the New Fish-Man Pirates. Vander Decken wants to marry Shirahoshi, while Hody Jones wants to take over the kingdom; allying with each other will help the each others' goals. Lampshaded by Jones in that, while he refuses to be anybody's subordinate, an alliance is okay.
Vander Decken IX

Debut: Chapter 606 (Manga), Episode 525 (Anime)
Devil Fruit: Mark-Mark Fruit
The legendary captain of the Flying Pirates and the Flying Dutchman, a mysterious ship that travels undersea. Is eventually revealed to be the descendant of the real deal, and a Bullhead Shark Fish-man. He's wanted in the Ryugu kingdom because of his one-sided love for the Mermaid Princess Shirahoshi. He eventually teams up with Hody Jones and the New Fish-Man Pirates in order to take over Fish-Man Island and marry Shirahoshi. However, after being rejected by the princess, he's now trying to kill her. He also has eaten the Mark-Mark Fruit (Mato Mato no Mi), a Devil Fruit that allows him to always hit his targets from anywhere.
- Adaptation Dye-Job: His skin is brown in the manga, but moves toward grayish-brown in the anime.
- Affably Evil: Decken is very polite and formal towards everyone, even when he is about to murder them.
- Arc Villain: Along with Jones, he is the main antagonist of the Fish-Man Island arc.
- Ax-Crazy: Decken's idea of giving presents to the object of his love is to throw weapons at her, then try to kill said person (and her friend) when they reject him. When that didn't work, he had the bright idea of throwing a massive ship half the size of Fish-Man Island at Shirahoshi to make sure he wouldn't miss (not that he ever does, but try blocking a ship that large coming your way). Hody repeatedly refers to him as "that crazy pirate", and he's none too sane himself, which is saying something.
- An Axe to Grind: Decken uses giant Battle Axes bigger than he is to send his messages to Shirahoshi and uses two hatchets as main weapons when confronting Shirahoshi and Luffy.
- Badass Mustache: Has a wavy, crazy-looking one.
- Bad Boss: Decken is willing to let his underling Wadatsumi die when he fell from Noah on Gyoncorde Plaza. Though despite this, Wadatsumi seems stil loyal to him and claims that he has never hurt him before, so he must have become a bad boss just after his Villainous Breakdown of the princess rejecting his proposal.
- BFS: The "gifts" he sent to Shirahoshi are literally bigger than he is.
- Beware the Silly Ones: How is a guy so incredibly eccentric dangerous at all? How about when he decided upon seeing Shirahoshi's ability to call Sea Kings, that he needed a treasure that instantly ages anyone who opens it so he could use it on her to age her into a woman so he can marry her? And then while doing that, decided that throwing weapons at her with his ability was a romantic proposition? And then when he gets told 'no' personally, finds a ship HALF THE SIZE OF FISH-MAN ISLAND and then THROWS IT AT HER (albeit he used his ability to do so)?
- Big Bad Duumvirate: With Hody Jones in the Fish-Man Island arc, as they both want to overthrow King Neptune, but...
- Big Bad Wannabe: Deckens somewhat of an anticlimactic antagonist, since he was easily pummeled by a tied-up Luffy.
- Cat Smile: Justified, since bullhead sharks are also known as 'cat sharks' in Japan.
- Colony Drop: He decided to throw the ancient ship of Noah, which is half the size of Fish-Man Island, at Princess Shirahoshi, after his rejection by her and defeat by Monkey D. Luffy. Doing so would easily destroy all of Fish-Man Island.
- Dual Wielding: When confronting Luffy and Shirahoshi, Decken uses two axes.
- Entitled to Have You: Involuntary celibacy is a defining character trait of Decken's; his attitude towards Shirahoshi is along the lines of this at first, which eventually progresses to If I Can't Have You . Either he gets her, or he kills her, and none of those Chads can stop him.
- Evil Cripple: Decken seems to have quite a hunchback.
- Evil Laugh: His Signature Laugh, "Bahohoho".
- Flying Dutchman: Decken is a reversal of the legend: Instead of being unable to set foot on land again, the captain (who is a Fish-man) can never swim again due to eating a Devil Fruit.
- Gonk: He is not Shirahoshi's type... nor anyone else's, for that matter.
- Gratuitous English: In the anime, "Dead or marriage!"
- Hoist by His Own Petard: After being impaled by Hody, he touches him and throws an axe at him, and then tries to kick him with concealed daggers in his shoes. Hody uses this to flip Decken into the path of his own oncoming homing projectile.
- Homing Projectile: Decken's Devil Fruit power allows him to mark a person by touching them, which allows him to throw any object at them with perfect accuracy. The projectile will not stop until it hits his target or impacts something of sufficient strength to arrest the momentum of the projectile. There is seemingly no limit to what counts as a projectile, from simple weapons to people to a massive ship that's half the size of the entire Fish-Man Island.
- If I Can't Have You : Decken toward Shirahoshi. When she rejects him, he decides to kill her. He even tries to drop a colossal ship on her.
- Important Haircut: After being 'rejected' by Shirahoshi, he shaves his head bald... but only the part that's hidden under his hat, so his outward appearance doesn't change.
- Impaled with Extreme Prejudice: By Hody, via his trident, for trying to screw with him.
- Insane Troll Logic: He wants to marry Shirahoshi for her powers. However, she is too young for him. But there are legends of a treasure belonging to the royal family that could age Shirahoshi to marrying age. So, how does he intend to get his hands on said treasure? By marrying Shirahoshi.
- I Work Alone: Or rather not as an underling to someone. An equal partnership is fine, though.
- Jerkass: As if stalking and throwing weapons at the Mermaid Princess for 10 years plus wasn't enough, Decken is not even above tossed a whole pirate crew at Shirahoshi's tower. He also tested his powers on poor Hachi and almost killed him with a hail of arrows. He even resorted to killing Shirahoshi (and Luffy) immediately after she rejects him, albeit in a polite manner.
- Kick the Dog: What he did to Hatchan is downright despicable at best.
- Laughably Evil: He's a complete and utter Jerkass, but he's just so darn odd; it's kind of hard to hate him as much as Jones.
- Legacy Character: The Vander Decken in the myths is actually the Grandfather of the current Captain.
- Made of Iron: The guy got thrown head first in to the ground by Luffy with a Jet Hammer attack. Later, Hody Jones stabbed him with his trident AND he got used as a shield by his own thrown axe. He is later left unconscious after hitting head on a stepping stone.
- The Magic Touch: His ability works like this. He "marks" the thing that he touched with one of his hands, then anything he throws with that same hand will home in to the marked thing. The marks will stay for as long as he doesn't touch anything else with the same bare hand (he wears a glove over the hand that touched Shirahoshi) or washed it (he never did ever since he touched Shirahoshi with it). Thus he's mostly limited with his other hand to throw things at other people, or if that fails, his Armed Legs.
- Multi-Armed and Dangerous: Decken, oddly enough, seems to have two extra legs. This is likely due to how the bullhead shark has three pairs of "belly fins" (two big near the head and four smaller) unlike the usual two pairs of the other kinds of shark.
- Nice Hat: Decken wears a nice-looking fedora.
- Not Quite Dead: Decken is still alive after the ordeal with Hody, and basically is this... and then he gets knocked out by hitting his head on a step. Could also count as Critical Existence Failure.
- Put on a Prison Bus: By the end of the Fish-Man Island arc, Neptune throws Decken in the palace prison along with Hody and his subordinates.
- Shark Man: It's not immediately obvious from his appearance, but he's a Japanese Bullhead shark.
- Sore Loser: After being rejected by Shirahoshi, Decken loses it and throws a bunch of axes at her... and later attemped to drop a colossal ship on her at cost of destroying the entire island.
- Also an example of Not Good with Rejection.
- Spanner in the Works: A villainous example that goes both ways. Decken's ultimate plan to kill Shirahoshi (the aforementioned Colony Drop) almost ruined both New Fish-Man Pirates' plans to conquer Fish-Man Island and the Straw Hats' plan to save it. Then Hody decided that Kill 'Em All is a good plan too...
- Stalker with a Crush: Towards poor Shirahoshi; he sent her love letters written on broad-axes and swords. Later in the series, after being rejected, Decken loses it and attempted to throw a colossal ship at her.
- Threatening Shark: Vander Decken himself is a Japanese bullhead shark Fish-man, who oddly has four legs. They are known as cat sharks in Japan, so he can double this up with Cats Are Mean, as well.
- Unwitting Pawn: Hody Jones only recruited him to not just help with the invasion of Ryugu Palace, but to kill Shirahoshi. Jones recognized the dangers the princess' control of Sea Kings would bring, and knew that Decken's If I Can't Have You mentality would bring him to kill her.
- Verbal Tic: Decken often interjects "No hazuda!" ("I think so!") into his sentences.
- Villain Team-Up: He refused one with Arlong, citing that he doesn't work under anyone. Conversely, he allied himself with Hody Jones, stating that he prefers being able to work alongside someone and be treated as an equal. Of course, he threw that out the window the moment Shirahoshi rejected him by throwing the Noah ship at the princess and subsequently Fish-Man Island, knowing that it would kill his allies in the process but not caring in the slightest.
- Would Hit a Girl: With the Mark-Mark Fruit power, Vander Decken sends various weapons at Shirahoshi on a daily basis, which is the reason why she had to live secluded in her bedroom for a decade. At the climax of the Fishman Island arc, Decken drops the Noah Ark on Shirahoshi, threatening the entirety of Fishman Island.
- Yandere: As if the fact that the person he's infatuated with is much younger than he is isn't already creepy enough, his idea of sending love letters is to throw axes and other weapons at her, weapons that are always dead certain to hit their mark. Shirahoshi had to spend ten years in her room just to protect herself from this guy. When she rejected him, saying he's not her type, he loses it and decided to outright destroy Fish-Man Island by using his powers to make a ship half the size of Fish-Man Island crash right into Shirahoshi, and by extension, the island itself all because if he can't have Shirahoshi, NO ONE CAN.
Debut: Chapter 628 (Manga)
A man who lived in the Void Century. He promised Poseidon and the people of Fish-Man Island that he'd lift Noah up to the surface, but failed in this commitment for unknown reasons.
- Chekhov's Gunman: His name is first mentioned along with the promise he made to Fish-Man Island. He becomes prominent again during the Wano arc when it's revealed that he left behind the treasure on Laugh Tale (One Piece?) and the Rio Poneglyph is basically the story he left behind.
- Connected All Along: Perhaps the ultimate example in One Piece. Joy Boy is connected to all the important MythArcs and related characters in the series: the map to the final island Laugh Tale is his, the Rio Poneglyph is his story and the One Piece may be the treasure he left behind.
- Greater-Scope Paragon: He's been gone for close to a thousand years, but he's the one who put the mythical One Piece on Laugh Tale, the final island. On a lesser scale, there's a promise he made to Fish-Man Island which, while he failed to fulfil, continues to be held by the Fish-men for someone else to complete. Finally, being someone from the Void Century who left the Poneglyphs, which the World Government has been censoring, puts him in direct opposition to their tyranny.
- Only Known by Their Nickname: He is only known as "Joy Boy". Interestingly enough, it's suggested in Oden's backstory that this is a title to be inherited.
- The Promise: He promised to bring the people of Fish-Man Island to the surface using the great ark Noah but failed to do so, and left an apology message to them on a Poneglyph in the Sea Forest. The Fish-men have kept the Noah in working condition over the centuries until someone else can fulfil Joy Boy's will. Fish-Man Island nearly breaks their half of the promise when Vander Decken uses his powers to throw the ship at the island after being scorned by Shirahoshi, and Luffy is almost forced to destroy the ship to prevent it from crashing and killing the island's inhabitants. Thankfully, the Sea Kings stop the ark under Shirahoshi's order.
- Shrouded in Myth: We know next to nothing about Joy Boy, and yet it was he who left something on the final island that Roger eventually found.
- "X" Marks the Spot: It's implied that he wrote the four red Road Poneglyphs which show the coordinates of a specific island each. By drawing a X between those islands, the location of Laugh Tale is revealed.
