Ulysses 31 (Japanese: 宇宙伝説ユリシーズ31サーティーワン, Hepburn: Uchū Densetsu Yurishīzu Sātīwan, lit. "Space Legend Ulysses 31", French: Ulysse 31) is an anime series (1981) that updates the Greek mythology of Odysseus (known as "Ulixes" or "Ulysses" in Latin) to the 31st century. The show comprises 26 half-hour episodes as a co-production between DIC Audiovisuel and TMS Entertainment.
The series follows the struggles of Ulysses and his crew against the divine entities that rule the universe, the ancient gods from Greek mythology. The Gods of Olympus are angered when Ulysses, commander of the giant spaceship Odyssey, kills the giant Cyclops to save a group of enslaved children, including his son. Zeus sentences Ulysses to travel the universe with his crew frozen until he finds the Kingdom of Hades, at which point his crew will be revived and he will be able to return to Earth. Along the way they encounter numerous other famous figures from Greek mythology, given a futuristic twist.
