Origin: Tartessos, Africa Birthdate: October 28, 1843 Nemo is the captain of the submarine called Nautilus, whose purpose is to destroy the Neo-Atlanteans at all costs. He is a mysterious man with a dark past; in fact only step by step we discover that he is Nadia's father and the real Emperor of Atlantis. Though he could have all mankind under his command, he chooses to live peacefully along with them on Earth, as he believes in humans and in their ability to love. While he acts cold and aloof when he first meets Jean, he nonetheless warms up to his outgoing cheerfulness and enthusiasm. Nadia, meanwhile, is very distrustful of him and is quick to accuse him of murder when he shoots a Neo-Atlantean to save her from death. However, she eventually learns to respect Nemo, and, at the end, at last acknowledges him as her father. Nemo then dies after overloading the Neo Nautilis's reactors to blow a passage out of Red Noah, permitting the rest of the cast to return to Earth. Nemo's name is a reminiscence of the Greek city Eleusis, the place in Greece where the followers of Demeter met annually to initiate members into the ways of the Earth-goddess, and Ra, the sun-god of Heliopolis in ancient Egypt. He is based on Captain Nemo (literally meaning "no man" in Latin). He also bears a striking resemblance to another famous anime captain, Bruno J. Global/Henry J. Gloval of the SDF-1 Macross in Macross/Robotech. Additionally, he wears a uniform similar to Captain Junzo Okita from Space Battleship Yamato/Star Blazers.
Sanson is 22 years old and the muscle behind the "Grandis Gang". He considers himself an expert on handling women and is an excellent artist with a rifle. He develops a relationship with Marie and tries to help Jean grow closer to Nadia.
Full Name: Ayerton Grenavan (Ayrton Glenarvan, Eaton Gurenaban) Species: Human Born: November 15, 1860 Origin: London, United Kingdom Ayerton is first seen in the series as a scientific officer aboard US warship Abraham; he states he's been sent on a secret mission to investigate the sea monsters phenomena. Later in the series, Jean and Nadia meet him again partially buried on a mysterious moving island, completely drunk and telling stories about a strange witch who inhabits the island (who naturally turns out to be Grandis). While on the island, Ayerton falls in love with Grandis, and to strike her, he pretends to be an English nobleman who's going to inherit a large wealth from his family. Ayerton is quite a weird, loudmouthed character, who is never really able to completely grasp the reality around him, and to tell good from evil. In the epilogue, Marie says that Ayerton was really a noble and wealthy man, and eventually he returned to his homeland. (Source: Wikipedia)
