Neptune

King of the Ryugu Kingdom. A coelacanth merman. Also known as "Sea God Neptune."

Born in Fish-Man Island. 70 years old. Birthday is July 3rd. Height is 12.2m. Cancer. Blood type X. Favorite food is seaweed salad.

He has a massive body that far surpasses ordinary merfolk, and sports a thick, bushy beard. He ends his sentences with "jamon." Once known as the "Great Knight of the Sea," he is now prone to back pain due to his age. He does not blame Jinbe for breaking the law that forbade blood transfusions to humans, showing his flexible thinking. His weapon is a trident. He is a practitioner of Merman Combat. He is the only one on the island who can communicate with whales. He shared a drink of friendship with the pirate Whitebeard in his younger days.

26 years ago, he ascended to the throne following the death of the previous king. A few months later, he met the Roger Pirates who visited Fish-Man Island. At that time, he was not yet married and was skeptical of Otohime's political demonstrations. Having once been a warrior who killed many humans who invaded Fish-Man Island, he felt he was not qualified to help his wife's activities and watched over her for many years.

He invites the Straw Hat crew to the Ryugu Palace after his beloved daughter Shirahoshi's pet shark, Megalo, is saved. Madame Shirley predicts that the crew will bring disaster to Fish-Man Island, so he initially tries to capture them, but ends up being captured himself. Later, when Hody Jones attacks the Ryugu Palace, Zoro and the others temporarily free him, but he is captured by Hody. He is nearly executed at Gyoncorde Plaza with his sons, but is freed by Luffy and his crew. After the coup ends, he imprisons Hody and Decken, places the remnants of the New Fish-Man Pirates under military control, and closes Fish-Man District.

In the Reverie arc, he travels to Mariejois with his children to participate in the conference. When Shirahoshi is almost captured by the Celestial Dragon Charlos, he nearly gives up on coexistence with humans and tries to strike Lucci, but stops when Saint Mjosgard frees Shirahoshi. After the conference, he returns to the Ryugu Kingdom under Garp's escort and is informed of an incident involving the royal family of the Alabasta Kingdom.
