Ep. 37: Nadia regresa con Red Noah y descubre que su hermano Neo es un títere controlado por Gargoyle.

37

Nadia is brought aboard Red Noah again, this time as it hovers in the sky, dwarfing even Gargoyle's battleships. There Gargoyle shows Nadia the ancient history of Atlantis, including an experimental massive "human" called Adam, and failed creations hovering in jars. She also meets Emperor Neo, who turns out to be none other than her long-lost brother -- a mechanical puppet under Gargoyle's control. Meanwhile, the New Nautilus has survived the destruction of Tartessos and sets off to fight back. Neo threatens the people around the world to surrender England, but just as the weapon fires, the New Nautilus intervenes, and the two crafts are face to face. (Source: Wikipedia)
