Ulysses - the man himself. His son Telemachus and his friends left the base at Troy for what should have been a routine journey to Earth. However the gods had other plans. His son was captured and held prisoner by the disciples of the Cyclops. The only way Ulysses could free him was by killing the Cyclops and thereby incurring the wrath of the gods. The punishment meted out to Ulysses was to have his companions put into a deep sleep and his navigation system wiped of the route back to Earth. Ulysses has to use all his cunning to survive the trials set by Zeus, find the route back to Earth and lift the curse befallen his companions.

Telemachus, son of Ulysses. He is seen here with his robotic companion No-no. Telemachus assumed the position of second in comand when the rest of the crew were put into suspended animation.

Numinor, Brother of Yumi. They both come from the planet Zotra. Unlike his sister Yumi, Numinor spends most of the time asleep with the rest of the crew. Yumi managed to temporarily lift the curse....

Yumi, younger sister of Numinor. Although not part of the Odyssey's original crew when it left the base at Troy on its journey to Earth, Yumi and her brother Numinor join up in the pilot episode, Vengeance of the Gods, after Ulysses rescues them along with his son, Telemachus. Yumi escapes the punishment by Zeus and plays a very active role as a member of the Odyssey's crew. She is exceptionally gifted, and possesses strong telepathic and telekinetic powers.

Zeus - the supreme overlord of Olympus. When Ulysses killed the Cyclops, its followers appealed to Zeus on behalf of Poseidon for revenge. Revenge was swift and severe: Ulysses's companions were put into suspended animation until such times as Ulysses could find the Kingdom of Hades. At each step of Ulysses's journey through Olympus Zeus used whatever cunning trickery he could to thwart Ulysses, more for his own amusement than out of any sense of just punishment.
