Voiced by: René Bériard (French)
An old scientist and space explorer who's tormented by the gods.
- Beard of Sorrow: He has a long beard, and he's been tormented by the gods for years and finds himself forced by the gods to lie to Ulysses and lead him to a certain death.
- Blinded by the Light: When he found a map of the Olympus galaxy inside the Zotrian ship by Atina's side, he tried to take it. The gods then punished him for this attempt and permanently blinded him with a flash of light.
- Conscience Makes You Go Back: Out of remorse for leading Ulysses to the spaceships graveyard, he decides to take the risk to go there to help him and amend.
- Cosmic Plaything: One of the many people the gods torment for (not even intentionally) defying them.
- Interspecies Adoption: He is human, and he adopted a Zotrian girl.
- Omnidisciplinary Scientist: Astronomy, archeology and paleontology.
- The Punishment: The gods blinded him for daring to acquire a map of Olympus.
- Sadistic Choice: The gods offer Heratos to recover his eyesight... provided he lures Ulysses to a magnetic graveyard for spaceships where he will die. If Heratos doesn't obey their orders, the gods will kill him and Atina.

- Graceful Ladies Like Purple: She wears purple, although to a lesser extent than Yumi.
- Happily Adopted: She was raised with love by Heratos.
- Nice Girl: Seems to be a common trait among Zotrians. She's as nice as Yumi.
- Pointy Ears: She has pointy ears, like all Zotrians.
- Sole Survivor: Her parents disappeared from the Zotrian ship — likely killed by the gods, and she was alone when Heratos found her.

The master of time itself. The other gods of Olympus cast him away and he captures Ulysses in order to bring him to them and earn back his place among them.
- Clock Punk: His realm and his servants are literally made of clocks.
- Evil Old Folks: He's a Time Abyss, and he's evil.
- Father Time: He is time personified, and a malevolent take at that.
- God in Human Form: He looks no different from an old human save for the face in the back of his head.
- The Hyena: The other face he has laughs evily pretty much all the time.
- Rapid Aging: One of his realm's powers is to curse people with this. This is what happens to Ulysses' companions and Numinor.
- Sadly Mythtaken:
- Nothing indicates that he's a Titan nor that he's the father of Zeus here, unlike his ancient Greek mythical counterpart.
- Chronos has never been depicted as Two-Faced, which is rather an attribute of the Roman god Janus. Interestingly, while not being the Roman equivalent of Chronos by any mean, Janus traditionally has time-related powers.
- Soundtrack Dissonance: His realm's beautiful theme contrasts heavily with his devious persona.
- Time Master: The exact extent of his powers over time itself in the Olympus are not known, but they are tremendous within his realm. He also has a giant clock that can rewind time itself, which Ulysses manages to use as a Reset Button to go back to moments before he entered the realm of Chronos.
- Two-Faced: He has two faces. One is that of an old man with a grey beard and it is dead serious. The other face is in the back of his head. It is beardless and lets out Evil Gloatings and Evil Laughs pretty much constantly.
- Villainous Rescue: He reverses time on the Odysseus just as it was about to explode when sustaining critical damages from a surprise and massive Tridents attack. Then he captures Ulysses.
A witch who lives on the moon that was once a vacation colony for Zotrians.
- Friend to All Children: It turns out she loves children more than anything else in the universe. Seeing Telemachus and Yumi is enough for her to stop attacking Ulysses.
- Misunderstood Loner with a Heart of Gold: She turned the Zotrians who tried to flee the moon to stone thinking they betrayed her by sending their kids away, but they did so only because the moon was moving away from Zotra's orbit. When she realizes it, she lifts her curse immediately and makes amends.
- Wicked Witch: Subverted. She looks like a crone, she turned a lot of people to stone, and she attacks Ulysses, but she only became evil because of a misunderstanding, and when she realizes it, she fixes her mistakes and resumes being the gentle witch she was before.

The king of winds and master of cosmic currents. He captures Ulysses to provide entertainment for his daughter's birthday.
- The Caligula: He rules a planet, seems to be lazy and enjoys nothing more than seeing people going through hell in his Deadly Games.
- Cosmic Entity: Albeit not on par with the gods of Olympus.
- Deadly Game: He puts Ulysses through a manhunt game to divert the guests of his daughter's birthday, much to her dislike.
- Evil Cripple: He never leaves his wheelchair.
- Evil Laugh: Lets out a few of these as he enjoys the games.
- Fat Bastard: He's quite heavyset.
- Heel Realization: Realizes the wrongs he has committed when his daughter almost dies, and lets Ulysses go as a result.
- Human Chess: The second ordeal he puts Ulysses through is a deadly human-sized chess game with the chess pieces out to kill him.
- It Amused Me: Puts Ulysses through Deadly Games just for his own amusement and that of his party guests.
- Pinball: For the third ordeal, Aeolus has Ulysses thrown in a giant pinball game and bounce on obstacles like a ball.

The king of Ancient Greece Corinth who once set out to find the secret of Death in the desert of Tartarus in order to be granted eternal life. The gods punished him for this, by condemning him to push spherical metallic debris into a pit. Forever.
- Beard of Sorrow: He's bearded, and constantly wonders when his ordeal will end.
- Be Careful What You Wish For: He wanted eternal life for himself and his wife Merope. The gods gave him eternal life... albeit with an eternity of suffering and a meaningless purpose.
- Cosmic Plaything: Needless to say, the gods are very petty with him.
- Fate Worse than Death: Pushing metallic debris into a pit forever under a blazing sun, and having only mushroom-beetles to eat.
- Godhood Seeker: He wanted to be as immortal as a god.
- Immortality Seeker: He once sought to find the secret of death, which according to him is the secret of eternal life.
- Impossible Task: More like endless task.
- The Punishment: The gods condemned him to push metallic debris spheres into a pit forever. The Classical Mythology one had to push boulders up a mountainside, which inevitably rolled down the mountain and he had to do it all over again.

A creature living in a pyramid in the Olympus. He captures space travellers and they have to answer his riddle correctly if they want to be freed.
- Adaptational Nice Guy: He is a wise ruler in his kingdom and has none of the man-eating and suicidal tendencies of the mythical Sphinx.
- Ancient Egypt: He looks nothing like an Egyptian Sphinx in appearance per se (he looks very much like his Greek myth counterpart minus the Gender Swap, and the riddle thing is purely Ancient Greece as well), but his kingdom is a Futuristic Pyramid and the dominant color on him and in his lair is sand-like and his clothing is really evocative of Ancient Egypt.
- Bizarre Sexual Dimorphism: He is more animalistic-looking than his daughter (including having fur) and uses four legs to walk.
- Cat Folk: A humanoid lion.
- Follow in My Footsteps: He wants his daughter to succeed him one day, and wants her to be as wise as he is.
- Futuristic Pyramid: His kingdom / lair looks like an ancient Egyptian temple.
- Gender Flip: The Classical Mythology Sphinx is female, this one is clearly male. Although, he does have a daughter whose devious personality is much closer to the mythical Sphinx.
- The Good King: He rules a kingdom and wants his daughter Hercronne to be wise enough to succeed him one day.
- I Gave My Word: Releases Ulysses after he answered his riddle and defeated Hercronne.
- Monster of the Week: A rather honorable one considering the many downright hostile threats Ulysses bumps into. The main danger for Ulysses actually comes from the Sphinx's daughter and not really from his (easy) riddle.
- Only Smart People May Pass: He lets the people who answer his riddle go. Those who cannot end up enslaved.
- Riddle of the Sphinx: The classic one, and no other: "What walks on four legs in the morning, two legs in the afternoon, three legs in the evening, and no legs at night?". Ulysses gives the right answer, naturally: "Man".
- Riddling Sphinx: He has the classic mythology attributes of the Sphinx (human head - although with Cute Little Fangs - and torso, the body of a lion and wings) and captures space travellers to ask them a riddle. Should they give the right answer, he will let them go. Should they give a wrong answer, they will become his slaves (or those of his daughter).
- Rogues' Gallery Transplant: The Sphinx is not part of the Odyssey myths, he is an enemy of Oedipus traditionally.
- Spared by the Adaptation: The mythical Sphinx commits suicide after Oedipus gives the right answer. This Sphinx, not being a proud and crazy creature, doesn't.
- Winged Humanoid: He has wings.
The devious daughter of the Sphinx.
- Bizarre Sexual Dimorphism: She is more humanoid than her father, she has no fur and she stands on two legs.
- Bratty Teenage Daughter: She's self-serving and demanding, and abiding by the rules of the Sphinx's kingdom bores her to no end.
- Cat Folk: She looks very much like a humanoid cat, minus the long hair and wings.
- Cute Little Fangs: Although not so cute given her devious personality.
- Heel Realization: She realizes how devious, selfish and corrupted by the gods she was upon watching her true ugly inner self in the Magic Mirror, and vows to become a better person afterwards.
- Master of Illusion: She can create multiple illusions of herself.
- The Mirror Shows Your True Self: Her father is wise enough not to let her watch her true inner self in his Magic Mirror. When she does, she realizes how ugly she is in the inside. She then cries and amends, wishing to become a better person.
- Pointy Ears: She has cat-like pointy ears.
- Self-Duplication: She can create multiple illusions who all have her appearance, although they're not physical.
- Spoiled Brat: She is quite selfish with none of the wisdom of her father, and badly wants Ulysses to belong to her.
- Villainous Crush: She has one on Ulysses and wants him to become her slave.
- Winged Humanoid: She has wings.
A half-human half-bull creature King Minos keeps in a labyrinth.
- Fed to the Beast: Minos disposes of his enemies and people he wants to get rid of by locking them in the labyrinth with the Minotaur, although the monster just kills them instead of devouring them like he does in the original myth.
- Impaled with Extreme Prejudice: Ends up impaling himself on the Laser Blade of Ulysses (hold by Theseus).
- Inescapable Net: Fights using a net in addition to his trident.
- Master of Illusion: Projects his image on many mirrors inside the labyrinth to confuse his prey.
- Our Minotaurs Are Different: He isn't much different from his Classical Mythology half-human half-bull hybrid counterpart.
- Prongs of Poseidon: Fights using a trident.
- Rogues' Gallery Transplant: Theseus is there and does finish the monster off, but it's Ulysses who does most of the fight against him. Not to mention Theseus kills the monster using Ulysses' sword.

The titan who supports the whole universe.
- Apocalypse How: Removing the stone from his forehead can cause this on a "universal" scope. His job is to prevent this.
- Atlas Pose: He's a rather faitfhul version of the Classical Mythology Trope Namer and takes this pose to prevent the universe from collapsing after Ulysses puts the stone back on his forehead.
- Cosmic Entity: He supports the whole universe thanks to the strength contained in the stone he has on his forehead.
- Gentle Giant: He means no harm to Ulysses and only seeks to maintain the balance of the universe.

- The Collector: He collects shrunken living creatures and ships shrunken to the size of models.
- Collector of the Strange: Collects shrunken creatures and ships alike.
- Hoist by His Own Petard: He gets hit by his own shrink ray after tripping. And his own cat chases him after that.

- Jerkass: He treats his people like dirt, to say the least.
- Shrink Ray: He possesses a prism that can shrink (or enlarge) anything.
