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 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.

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.

Ulysses is saved from a Trident attack by Chronos, the god of time, who wants to use him as leverage to be allowed to reenter the home of the gods.

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.

The Odyssey comes across a planet ruled by the evil Antipodes, who keeps a menagerie of miniaturized pets. Antipodes detects and shrinks down the Odyssey using his powerful prism, and the ship crashes down into the sea, close to his island. Ulysses undertakes a little reconnaissance using one of the shuttles, but ends up being trapped in an oyster and encased in a pearl. Losing track of Ulysses, Telemachus takes another shuttle to his father's last known location and encounters lots of other miniaturized shipwrecks on the seabed. Telemachus' shuttle is scooped up, along with the shipwrecks by fishermen working for Antipodes. The pearl containing Ulysses is taken to Antipodes, and Ulysses manages to get his shuttle free. Discovering how to use the crystal to return themselves to normal size, Ulysses and Telemachus avoid Antipodes and his cat and manage to shrink him down as well as restoring themselves. They take the prism with them and enlarge the Odyssey back to its original size, whi

Exploring a planet remarkably similar to the Earth of 200 million years ago, with the continents different from the present, Ulysses and the children quickly come under attack by giant mutant vultures. Forced to land, they seek refuge in a cave and discover an advanced underground city. There, they come across a strange group of large egg-shaped structures, while Sherka warns Ulysses that there are about to be immense seismic disturbances on the planet. Counting nine eggs, one for each planet in Earth's solar system, Ulysses opens the third egg, representing Earth. A winged woman named Sauria emerges and tells Ulysses that they are on Earth and that her people were all put in suspended animation to protect themselves from a huge flood covering the Earth, when the gods lived on Earth and her people were their slaves. The gods left without them, and used the mutants vultures named Keconopters to protect their spaceships before they left. In secret, Sauria's people built the Ark, containi

Near the zone of the Kingdom of Hades, Ulysses and the children are rendered unconscious, and the Odyssey is taken into another dimension. Their companions are taken from their chamber and placed on the Odyssey's bridge. An Earth-like planet is detected, and the now-awakened Ulysses uses a shuttle to investigate. As he does so, his companions are manipulated into piloting the Odyssey to the planet, known as Aim, by Circe the enchantress. She turns the Odyssey's crew into swine so as to be her slaves. Ulysses encounters a space commander named Hermes who tells him that his crew were taken by Circe, who wants to build a giant tower of knowledge. When she has all the knowledge of the universe, she will be able to stand up to the gods. Hermes shows Ulysses how to get to the tower, and once there he and Nono encounter Circe's librarian, also named Hermes.

Telemachus spots a planet with a giant hole in its side, and Ulysses takes the Odyssey into the planet's hole to protect it from the Tridents. As they enter the hole, they notice that the Tridents are unable to follow them, exploding when they try. Soon, all the damage incurred by the Odyssey repairs itself, and a voice introducing himself as the Magician in Black tells them that he was responsible. Ulysses and the children are transported to his palace, and there they meet the Magician, who tells them that he is more powerful than the gods. To prove it, Ulysses asks him to free his companions. The Magician agrees, for an undisclosed price, and soon they are reunited with their revived friends. Later, the Magician holds a feast for Ulysses and his companions.
