Nemo

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 whose dark past we discover step by step

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.
