AppearanceEdit

Rather than being an inanimate object like usual weapons, Poseidon was a mermaid belonging to the Ryugu Kingdom's royal bloodline. After she died, her name was treated as a title given to a mermaid who was born within the royal family and had the same power she possessed when alive, known colloquially as the "Mermaid Princess" (人魚姫, Ningyo Hime^?). Currently, Shirahoshi has inherited Poseidon's power and her name.

Abilities and PowersEdit

Poseidon has the power to communicate with and control Sea Kings, an ability that even the most powerful merfolk cannot do. This is considered to be a powerful weapon because of the Sea Kings' destructive potential to sink islands with ease, and to control such a force is considered to be one of the most fearsome abilities in the entire world. While guided by the power of love, it can save thousands of lives, but with evil intentions, it can sink everything into the ocean.^[1] The Sea Kings refer to the Mermaid Princess as their "queen".

The current Mermaid Princess, Shirahoshi, has demonstrated, when her powers first awakened at age six, no control over her own abilities and will inadvertently summon Sea Kings when she cries out loud, which is very risky to her kingdom. Ten years later, during the battle against the New Fishman Pirates, she fully awakened the ability and seemingly gained control of it.

HistoryEdit

Original PoseidonEdit

Poseidon lived during the Void Century and made a bargain with Joy Boy. She would use her powers to command the Sea Kings to bring Noah to the surface of the world and activate its intended mission of which the details would be revealed when raised. However, Joy Boy failed in his commitment to Poseidon, due to unknown reasons.

LegacyEdit

After the Void Century, Poseidon disappeared from records, with the only information on her being found on the Shandora Poneglyph ^[2] in Sky Island, and the Ryugu Poneglyph located in Sea Forest (which is written as a letter of apology from Joy Boy to Poseidon, apologizing for breaking his end of the bargain).^[3]

Even after her death, her power did not die and Poseidon's ability was passed through the generations of the royal family, although never awakened. Meanwhile, Fishman Island attempted to keep its end of the bargain despite Joy Boy breaking his. The World Government spent the next few centuries trying to avoid the awakening of the Ancient Weapons by outlawing the reading of the poneglyphs.

Poseidon's story become a legend within Fishman Island over time and stories were passed throughout the Ryugu Kingdom royal family. According to one such legend, a mermaid would be born with the ability to control the Sea Kings; on that day a man would come to guide her. The first Vander Decken traveled to Fishman Island to find this mermaid. However, he failed to find her and the story was passed down through his descendants as well, with each new Vander Decken trying to find the princess.

Current PoseidonEdit

Eight years before the start of the series, Princess Shirahoshi had unwittingly demonstrated the ability to summon Sea Kings when her mother was in danger of being shot by World Noble Mjosgard. Her cries summoned a group of the sea monsters, allowing her mother and Vander Decken IX to find out about her ability. At this point, Decken deduced that Shirahoshi is the Mermaid Princess of legend that his family had been searching for and decided to marry her to gain access to her fearsome abilities (as well as her unparalleled beauty), leading him to send her threatening marriage proposals for the next ten years. Otohime, knowing that such powers can be both beneficial and deadly, had her three sons train hard to become warriors in order to protect Shirahoshi when the time came. Shirahoshi's power was fully awakened during the fight with the New Fishman Pirates, which Neptune noted was not a good thing.

TriviaEdit

• In Greek mythology, Poseidon (Ποσειδών) is the god of the sea, water and earthquakes. This notably keeps in theme with the rest of the Ryugu Kingdom royal family; Neptune is the Roman name of Poseidon and Otohime is the daughter of the Japanese sea-god Ryūjin.
