A craftsman at heart who takes pride in his work. His hobby is keeping the ship clean. As a result of combining Triton—who is honest, kind, and loved by all—with Prince Dakkar—the incarnation of action who follows through on his convictions—his personality deviates slightly from both originals. Ryder Nemo has gained a single conviction: "Resistance against rule and trampling." He does not tolerate the oppression of the weak by anyone, but this conversely leads to a rejection of modern human society and consumer civilization. As Nemo, he frowns upon European culture and takes a similar attitude toward Greek culture. However, since the world of the sea has no borders, Triton, a child of the sea, is considered safe—in fact, he loves it. He is unsociable and blunt, often saying he "hates humans," but this is because Prince Dakkar's memories frightened the innocent soul of Triton, making him wary of the humans who create tragedies. His true personality is honest and friendly; he will never abandon someone he likes. He is strict with others as a captain, but even stricter with himself. He possesses an indomitable heart that seeks breakthroughs and solutions in any predicament, so his expression is always cool. However, if a shadow appears on that face, it means there is truly "no way out no matter what is done." He doesn't much like being called "Captain," but he grudgingly accepts it as better than his other nickname, "Prince." He seems to have an obsession with the sea, and sea-related metaphors often mix into his speech. Compared to the "Nemo Series" below, perhaps because he stands in the position of "Captain," he is said to be good at summarizing the opinions of the series and making quick decisions. Master: Ritsuka Fujimaru Strength: C Endurance: B Agility: C Mana: A Luck: A Noble Phantasm: B I Am the Journey, the Great Ram Nautilus (Great Ram Nautilus) Rank: A Type: Anti-Sea Noble Phantasm Range: 2–70 Maximum Targets: 1 enemy (Game Material) / 200 people (Book Material) "Fine, it's time to show you I'm serious." "Launch!" "Target spotted!" "Directly above the ship!" "Internal combustion engine, maximum! Life support, maximum! Fried eggs, OK!" "Alright, rapid surface! We are the spear of the Sea God! 'I Am the Journey, the Great Ram Nautilus'!!" This is the submarine "Nautilus" itself, his beloved ship. It is the crystallization of over-technology that people dreamed of—a versatile vessel that sails all seas and weathers all storms. Because the submarine is inseparable from the existence of Nemo, as a Servant, he is integrated with the submarine Nautilus and shares its damage. When using the Noble Phantasm, he changes form into a state centered on the submarine Nautilus (in the motion, he boards it himself) and performs a charge using the equipped great ram. No matter how giant the enemy is (giant squid, giant battleship, etc.), he does not flinch, possessing a special concept of colliding with and breaking through them. It can be used even in places without water (on land or in the air), but it has a rare property where the accuracy and power significantly increase if the field is underwater or in the sea.

Though described as clones, their essence is "humanoid terminals adjusted for autonomous operation by subdividing and personifying Captain Nemo's abilities and 'what-if' possibilities." Deploying or retracting them can be done at will by the Captain, the main body. Conversely, he cannot seem to control their individual wills, but they can share information with each other. From depictions in the story, they appear capable of autonomous operation and information sharing even when separated by considerable distances. On the other hand, while they share information, each series has a different personality, so Nemo's true feelings or secrets are sometimes exposed through other Nemo Series. Nemo Marine Nemos who serve as workers on the Nautilus. All are male. Only this individual appears in multiple units at once. Their personalities are generally lively and childish. In battle graphics, they assist in attacks under Nemo's instructions. Nemo Bakery The cook Nemo in charge of the galley. Female. She has a bright and caring personality.
