The royal families of One Piece showcase unique traditions and ideologies. Despite their reputation as pirates, the Straw Hat Crew has earned the trust of various royal families, often aligning with princesses in their quests.
Although Shirahoshi does not formally join the crew like Nefertari Vivi, she stands out as the most influential princess among their allies. The Neptune Family exemplifies commitment to their people, tirelessly striving for equality between fishmen and other oceanic species.

Fisher Tiger’s Fight for Freedom
Numerous figures have championed freedom for fishmen, each with their distinct approach. Fisher Tiger, a former slave turned pirate, made a huge impact by liberating slaves of all species. He established the Sun Pirates and provided a haven for fishmen seeking camaraderie and purpose.
His legacy endures through figures like Jinbe, Arlong, Hody Jones, and Koala the Revolutionary, all of whom have unique ties to Fish Man Island’s royal family. Although their beliefs may diverge, Fisher Tiger’s influence profoundly shaped the island’s history and future.
Neptune: The King of the Ocean
As a coelacanth merman, King Neptune’s towering stature matches his commanding personality. While his impulsive decisions, such as arresting the Straw Hats, may seem rash, they stem from his deep concern for his people.
His unorthodox thinking allowed him to forge alliances, eventually entrusting the crew with safeguarding Fish Man Island. Unlike his late wife, Otohime, Neptune focused on preserving her vision and prioritizing the well-being of his children after her death. His knowledge of the Void Century and poneglyphs adds another layer to his cautious leadership.
Otohime’s Pursuit of Equality
Otohime, a goldfish mermaid, devoted her life to fostering peace between fishmen and humans, advocating for cooperation and coexistence. Her ideals often clashed with Fisher Tiger’s views, yet mutual respect existed between them.
Her influence extended to figures like Donquixote Mjosgard, who began championing equality. Tragically, her assassination by Hody Jones, who framed a human for the act, could not extinguish her message. Her children and Jinbe carry forward her dream, striving to protect Shirahoshi and achieve harmony.
Fukaboshi: A Leader in Waiting
Fukaboshi, a shark merman and presumed heir to the throne, dedicates himself to his people. Whether fulfilling his mother’s vision or delivering Jinbe’s message to Luffy, his commitment is unwavering.

Despite his temper flaring when his sister is threatened, Fukaboshi consistently seeks fairness in his decisions.
Ryuboshi: The Spirited Prince
Ryuboshi, an oarfish merman, often blends music into his speech and actions. Alongside his brother Manboshi, he used song and dance to comfort Shirahoshi during her childhood, continuing this tradition even after Otohime’s death.
While his role in major events is less pronounced than Fukaboshi’s, Ryuboshi remains fiercely protective of his family and fights when necessary.
Manboshi: The Energetic Youngest Prince
Manboshi, an opah merman, exudes unbridled energy and enthusiasm. His penchant for singing and dancing often brightens tense moments.
Despite his lighthearted nature, Manboshi knows when to focus on serious matters, such as fighting the New Fish Man Pirates or supporting his siblings during critical times.
Shirahoshi: Poseidon’s Power
Shirahoshi, a smelt-whiting mermaid and the youngest in her family, possesses the immense power of Poseidon, granting her control over the sea kings.
Despite her fragile demeanor, shaped by years of isolation, she exhibits bravery and determination in spreading her late mother’s ideals. Protected by her family, Shirahoshi remains a vital figure in the quest for equality and harmony.
The Neptune Family’s Enduring Legacy
The Neptune Family’s deep ties to the Void Century and their association with figures like Gol D. Roger place them at odds with the World Government.
Shirahoshi’s status as Poseidon further complicates their precarious position. Despite these challenges, the family continues to fight for their people’s rights and collaborate with allies, even pirates, to secure Fish Man Island’s future.
