Ulysses 31

In the 31st Century at the planet Troy, the space explorer Ulysses prepares to take his ship, the Odyssey, and its crew back to Earth, where political unrest between impatient Princes threatens the peace. Ulysses must also return to the Earth before the next comet travels across the sky there, otherwise his wife Penelope's duty will be to find another husband. Before their journey begins, the Odyssey's crew celebrates Ulysses' son Telemachus' birthday, and he is given a new little robot named Nono. On the Odyssey's journey back to the Earth, the Odyssey's computer Sherka detects a previously unknown planet. As the planet's location is logged on file, a white light emanates from the planet and abducts Telemachus. He is taken prisoner and comes across two other children from the planet Zotra (also known as the White Planet), Yumi and her brother Numinor. He tells Telemachus that they are all prisoners of the disciples of the Cyclops. The Cyclops steals energy from children and gives it t

The ship passes a moon that brings Numinor back to life, since it's from his home planet of Zotra. When they investigate, the children disappear and Numinor suspects they've been kidnapped by a legendary witch.

On an isolated asteroid, the blind Heratos and his Zotrian companion Atena attempt to contact the Odyssey. The gods of Olympus, who took Heratos' sight, offer to return it if he sends Ulysses to the graveyard of wrecks and hulks. After they threaten Atena, he agrees to betray Ulysses. The Odyssey receives their signal and heads towards Atena and Heratos' asteroid. Atena explains how she was found abandoned as a child in a spaceship by Heratos, and Heratos himself tells Ulysses of a black sphere that lay next to Atena in the ship. After touching the sphere, he found it to be a ship's log showing a map of Olympus and the route through the galactic glaciers. To prevent him from knowing too much, the gods took away his sight, and he and Atena ended up stranded on an asteroid. Heratos pretends give Ulysses directions to the galactic glaciers, but they are instead directions to the graveyard of wrecks and hulks. After confessing his crime to Atena, they both travel into space after Ulysses.

Aeolus, King of the winds, kidnaps Ulysses to provide entertainment for his daughter's birthday party. Unable to watch her father's cruel sport, she frees the captives and helps them escape.

Ulysses encounters Sisyphus, a king condemned to fill a crater with boulders for all eternity for having dared to want the secret of immortality. Zeus has promised Sisyphus he can leave if he makes Ulysses take his place.

The Odyssey comes across a lifeless city world. On hearing that its people had the technology to bring the dead back to life, Yumi takes Numinor to the planet to revive him. However, she learns why there is no life in the city.

A space storm revives the companions as crazed automatons who take over the ship and try to crash it into space glaciers.

Passing through the domain of the great Sphinx, Ulysses must answer his riddle to leave safely. His treacherous daughter kidnaps the children and plots to make Ulysses her slave.
