Emperor Neo is apparently the leader of the Neo-Alanteans. Later in the story we discover that he is Nemo&#039;s son and Nadia&#039;s brother, but his body was destroyed in the collapse of Tartessos, and was mechanically recreated by Gargoyle. He is then controlled like a puppet by him; he tries to take over the world using his psychic powers and technology, and also shoots his own father against his will.~!In the end he will eventually liberate his free will and love for his family, sacrificing himself to save Nadia.!~

In 1889, the world is on the pinnacle of great discoveries in technology. In mankind's grasp for the future, a sinister foe known only as Gargoyle, obsessed with restoring the former Atlantean empire to the glory it once held, begins his plans to take over the world. Nadia, with the help of a young inventor, Jean Raltique, and the mysterious captain Nemo of the submarine Nautilus, must fight to save the world from Gargoyle and Neo-Atlantis. Based on the Novel '20,000 Leagues Under the Sea' by Jules Verne.<br><br>
