The Strongest Merfolk In One Piece

Key Takeaways

Merfolk are genetic relatives of fish-men, with both facing historical oppression and slavery.
Strong merfolk, like Hyouzou and Aladine, can hold their own in combat.
Shirahoshi, is likely the most powerful mermaid, due to being an ancient weapon.

As a long-time fan of One Piece, I must say that the characters from the Ryugu Kingdom are truly fascinating and unique, each with their own strengths and vulnerabilities. Among these, the trio of Manboshi stands out as a more comical duo, yet they possess an impressive amount of power that requires energy steroids for others to surpass.

In the popular series One Piece, there’s an interesting and lively group known as Merfolk. They share a genetic link with fish-men, but unlike their counterparts, merfolk’s fishy traits are more prominent below the waist instead of on top. Just like fish-men, they can interbreed with humans because all three species – merfolk, fish-men, and humans – share a deeper ancestral bond.

Despite their history of oppression and enslavement, most merfolk are compelled to remain underwater due to these circumstances. However, it’s been demonstrated that some merfolk can assert their independence. Here are some of the most powerful merfolk we’ve seen in One Piece so far.

5 Hyouzou

Officer/Hired Sword Of The New Fish-Man Pirates

Debut: Chapter 607 (Manga), Episode 527 (Anime)
Species: Blue-Ringed Octopus Merman

Previously, Hyouzou was renowned as the mightiest swordsman on Fish-Man Island. He attracted the attention of Arlong, but their alliance never truly took shape due to Arlong’s reluctance to compensate for his skills. According to Hyouzou, it was this very reason that led Hatchan, another skilled swordfish-man octopus, to join the Arlong Pirates instead.

Hody Jones, having learned from Arlong’s errors, agreed to compensate Hyouzou. The sea-dweller held mixed feelings towards Hody’s convictions, but served as an official due to the monetary incentive. He demonstrated remarkable speed by thwarting Luffy in his Gear 2 transformation and was capable of defeating numerous adversaries. Owing to his resemblance to a blue-ringed octopus, he possessed the ability to secrete poisonous substances. However, Hyouzou was no rival for Zoro; this became even more evident after consuming excessive energy steroids, which prematurely aged him into a weakened old merman.

4 Aladine

First Mate/Doctor Of The Sun Pirates

Debut: Chapter 620 (Manga), Episode 540 (Anime)
Species: Goatsbeard Brotula Merman

Originally, Aladine served as a slave alongside his ex-captain, Fisher Tiger, and several of his comrades. Currently, he stands out as the only identified member of the Sun Pirates who was part of the crew before Tiger’s demise and has continued to be associated with them since then. Most of their known associates either formed or joined other pirate crews following these events. During Jimbei’s tenure as captain, Aladine held a position of authority, possibly even succeeding him as captain due to Jimbei’s departure.

Beyond his medical background, Aladine exhibits proficiency in a unique form of karate that involves fish-men, able to engage in combat with figures such as Charlotte Oven, a well-known member of the Big Mom Pirates. Similar to many of his species, he is also an adept swimmer. However, unlike certain mermen, his physical structure enables him to navigate land without requiring extra assistance.

3 The Neptune Brothers

Princes Of Ryugu Kingdom

Debut: Chapter 609 (Manga), Episode 528 (Anime)
Species: Shark Merman (Fukaboshi), Oarfish Merman (Ryuboshi), and Opah Merman (Manboshi)

Fukaboshi is the second son of Neptune and Otohime, and he’s the one in line for the throne. Much like his family, he remains steadfast in pursuit of his mother’s vision for harmonious relations between humans and fish-men, regardless of any challenges that may arise from either side. Generally speaking, Fukaboshi is portrayed as a responsible and serious character, contrasting with his younger brothers, Ryuboshi and Manboshi, who are more lighthearted and humorous in their interactions.

The trio exhibits significant strength; the New Fish-Man Pirates require performance-enhancing supplements to surpass their capabilities. Unlike their father, who is past his prime, these three are at the peak of their abilities, with Fukaboshi demonstrating an impressive ability to heal quickly. However, even with their natural talents, they couldn’t withstand the pirates after consuming the steroids. In the end, it was the Straw Hats and Jimbei who provided additional assistance.

2 Neptune

Ruler Of Ryugu Kingdom

Debut: Chapter 611 (Manga), Episode 530 (Anime)
Species: Coelacanth Merman

As a passionate admirer, I’d like to share that I am Neptune, the consort of the revered mermaid queen Otohime, who yearned for tranquility among our people. In her memory, I strive unceasingly to preserve her dream. My subjects find me favorable, and I possess an unusual talent – the ability to converse with whales, a skill seldom found among my kin. Primarily, I utilize this gift to communicate with my colossal companion, Hoe, who not only serves as my loyal pet but also as my means of swift transportation.

In his seventies, Neptune remains a powerful merman, able to resist Hody’s attacks despite his energy-boosting steroids. However, it must be noted that age has begun to take its toll on him; even so, if he pushes himself too hard during battles, his physical resilience may not hold up.

1 Shirahoshi

Princess Of Ryugu Kingdom

Debut: Chapter 612 (Manga), Episode 531 (Anime)
Species: Smelt-Whiting Mermaid

As a fervent admirer, I’d put it this way: I myself am talking about Shirahoshi, the unique daughter of Neptune and Otohime. She stands out with her colossal stature, towering over her mother and older brothers even at less than a year old. Due to spending most of her life confined in a locked tower and being doted on by family, she’s rather delicate. This vulnerability is so pronounced that Luffy, upon our initial encounter, jokingly labeled her as a crybaby. When it was time for her to step out of her quarters after several long years, she required Luffy’s protection.

Initially trying to muster courage when reuniting with her family at the Levely, she is swiftly seized by World Noble Charlos, intending to enslave her. However, just in time, Donquixote Mjosgard, another World Noble, along with Sai and Leo from the Straw Hat Grand Fleet stepped in, rescuing the young mermaid from this perilous situation.

Despite her vulnerable state at present, it is a real possibility that Shirahoshi is far more powerful than her relatives have put together. This is due to her being the ancient weapon, Poseidon, a trait she inherited from a distant ancestor. Poseidon’s main asset is the ability to control and communicate with sea kings, powerful beings that populate every known ocean. They respond to her feelings and desires, such as her wish that Luffy would be helped, even if she did not directly request their assistance. Beyond this fact, she could likely grow in physical strength if she wished to, seeing as her relatives are among the most powerful merfolk in existence.
