A pupil of Shaina and one of the main contenders for the Pegasus Cloth, which he loses to Seiya. He mostly serves as Shaina's right hand man.
- Badass Normal: Cassios is strong enough to fight Saints if they are not invested fully in the fight, as Shun and Shiryu learn. He wasn't a candidate for the Pegasus armor for nothing.
- The Brute: He has no special techniques, only brute force.
- Dark-Skinned Blond: In the manga.
- Dumb Muscle: Didn't even know about the cosmos when he fought Seiya the first time. Seiya even called him dumb.
- Ear Ache: Got his cut by Seiya during their fight for the Pegasus Cloth.
- Even Evil Has Loved Ones: He truly cared for his Sexy Mentor Shaina.
- Hellish Pupils
- Heroic Sacrifice: He takes Seiya's place and dies during the fight with Leo Aiolia, in order to wake Aiolia from the control of Saga's Genro Mao Ken. Not for Seiya, mind you, but to avoid Shaina the pain of losing the man she loved.
- Laser-Guided Karma: When he first fought Seiya, he liked to threaten him with taking apart his limbs bit by bit, and offered to start with his ear. That very same fight it's he who loses his ear to Seiya.
- Mauve Shirt
- Monstrosity Equals Weakness: He has enormous physical strength and stamina to match his huge body, but due to not having mastered the use of Cosmo, in the end he's less powerful than an actual Saint.
- Muscles Are Meaningless: Because the Cosmos is everything; with him in particular this is very relative, as he is strong enough to kick Shun and Shiryu's asses in order to prevent them from fighting Aiolia, showing that he is more than capable of fighting Saints if they are caught unaware. A normal man would have been shred to pieces by Aiolia and he was still standing when the barrage ended.
- Not Drawn to Scale: He get's pretty big at times during the first episode. When the twelve Houses arc rolled around they found a more realistic height.
- Politically Incorrect Villain: In the beginning, he mocks Seiya for his Japanese heritage, saying that only Greeks should be able to inherit the Cloths. To be fair, quite a few of the other Saints in the beginning also expressed this opinion.
- Undying Loyalty: To Shaina.
- Unskilled, but Strong: He tossed Shiryu and Shun around like ragdolls, and was briefly able to restrain Aioria (a Gold Saint himself) in a bearhug to prevent him from beating up Seiya, but he never mastered Cosmo and thus, never learned any techniques that make use of it, so he loses his life to Aioria in the end.
A former apprentice who was cast down as a candidate for saint for his violent tendencies and penchant for murder.

- Animal Motifs: Tiger.
- Cain and Abel: In the childhood friends sense, the Cain to Shiryu's Abel.
- Deceptive Disciple: Played straight with he and Libra Dohko. Though Ohko was more of a JerkAss than anything.
- Delinquent: He was quite powerful, but he had a violent temper, breaking the rules and seeking fight with whoever he could.
- Died in Your Arms Tonight: Shiryu's. Before dying, the hatred that Ohko held for the one who prevented him from becoming a Saint disappeared, and the brother-like affection for him returns. So he dies more or less in peace in Shiryu's arms, asking him to go on forward.

- Filler Villain: Appears in two anime-only episodes.
- Red Oni, Blue Oni: Red to Shiryu's blue.

Gigars' second-in-command and eventual successor.
- Evil Redhead: Has red hair.
- Filler Villain: He and Gigars appaer only in the anime.
- No-Nonsense Nemesis: When he's put in charge of recovering the Gold Cloth helmet, his first move is to send in Lizard Misty, a fighter so respected that Shaina stopped demanding she was sent the moment she heard because it was obvious he'd come back triumphant. Deconstructed when Misty dies, as the only Silver Saint of comparable power is Shaina and he has no authority over the Gold Saints.
- Spell My Name With A B: Also known as Bhaton.
- Smug Snake
- The Un-Reveal: Is never stated if he is a Saint or not.
- What Happened to the Mouse?: Disappears after the Sanctuary's battle.

- The Medic: She cares for Ikki after training sessions by sneaking in the dungeon where he was resting.

- One True Love: Ikki doesn't show it much, if at all, but considering that Ikki was willing to kill a perfect illusion of his own beloved younger brother, and still admits to Casa that had he searched his mind more thoroughly and found Esmeralda earlier, he would have fallen for his trap, then hell, yes she's this.
- Related in the Adaptation: To Master Guilty. Which arguably makes her treatment by him even worse.
- Too Good for This Sinful Earth

A childhood friend of Seiya and the caretaker of the orphanage where both her and Seiya grew up.
- All Love Is Unrequited: Poor girl doesn't even get to tell Seiya her feelings proper before she and the orphanage are unceremoniously chucked out of the narrative.
- Dub Name Change: "Lamia" in Italian.
- Girlish Pigtails: Her hairstyle.
- Nice Girl: Is really patient with the children at the orphanage.
- Out of Focus: When she was first introduced, she and Seiya knew each other well, and even had a bit of Ship Tease due to her one-sided crush on Seiya. By the time the Hades arc rolls around and she's finally referenced again, Seiya can only remember the poor girl as that little girl he made cry one time when he stomped in the flowers. Even when the panel itself had her with a nametag.
- Team Mom: She chose to stay at the orphanage she was raised in and became this to the children there. The anime had her in the vicinity of three troublesome kids most of the time she was given some screen, plus she explains to Seiya that she's good with kids so she voluntarily asked the director if she work for the same place.
- Tsundere: When she was young.
- Shy Blue-Haired Girl: Has blue hair and is very shy.
- Unlucky Childhood Friend: To Seiya.
The mysterious head of the Kido Foundation, Mitsumasa Kido is a Japanese multimillionaire who adopted Saori Kido as his granddaughter and a multitude of children that wound up growing up to be the Saints of Athena.
- Abusive Parents: Considering that the Bronze Saints are his biological kids (manga) or his pupils (anime), the Training from Hell he made them go through merits as abusive for sure.
- The Chess Master: He starts the Graude Foundation and uses it to find his large number of children (or locate and pretty much abduct a just as large number of orphan boys) that, in the future, become the Bonze Saint and Athena's protectors.
- Kansas City Shuffle: In the manga, he changes the appearance of the Sagittarius Cloth on purpose, to the point that the Silver Saints think it is a fake.
- Karma Houdini: Sacrifices his own children, gets to die of old age before any of them could make him bleed for it.
- Pet the Dog: For all that he mistreated the Bronze Saints, at least he raised Saori to be respectful of them and scolded her for treating them like slaves.
- Related in the Adaptation: In a reversal, the anime says all the Bronze Saint kids are his adopted children. In the manga, he was really their biological father, a fact which drives Ikki in particular pretty mad.
- Really Gets Around: In the manga, he fathered all those young Saints to different women.
- Screw the Rules, I Have Money!: He holds the Galactic Tournament and reveals the Saints to the world, much to the cringe of Sanctuary. They don't take it well.
- Secret Keeper: He keeps hidden that Saori was the reincarnation of Goddess Athena, who reincarnates in a human being every 200 years.
- Well-Intentioned Extremist: He arranged for a bunch of boys (either his biological sons or helpless orphans, depending on the version) to be subjected to lots of abuse and Training from Hell, because he sincerely believed that it'd help to save the world. The anime shows that he was very aware that the boys would suffer horribly and wasn't happy with the idea itself, such as when he tells Saori about the boys' future as her Saints and tells her to treat them well when they return.

Natassia was Cygnus Hyoga's mother who perished after her ship sank in the Arctic Ocean, leaving the ship stranded from the thick icy surface. She is the main reason Hyoga became a Saint.
- Cursed: In the DiC dub. While trying to protect young Hyoga, an evil sorcerer attacked. She was so weak and alas they were too strong. Now she sleeps in the bottom of the ocean awaiting the day that her beloved son, Hyoga will win the Gold Cloth and use its power to wake her up. Believe it or not, this is the summary that Hyoga gave while using his surfer accent.
- Human Popsicle: She died when the ship sinks into the icy sea near Siberia. As the ship sunk in the icy sea, her body remained uncorrupted.

Tatsumi is Mitsumasa Kido and later Saori Kido's personal butler. He is the executor of the Kido Foundation in Saori's absence.
- Battle Butler: He is apparently good at kendo. Not that it does him any good in a show where superpowered boys are the rule.
- Butt-Monkey: He always tries to be strong and protect Saori but even the Sanctuary soldiers can defeat him. Is the series' comic relief.
- The Dog Bites Back: Ikki comes back six years after the huge beatdown Tatsumi gave him, and after his fiery entrance he makes a vow before the crowd to make him pay for what he's done. And he fills it right there.
- Characterization Marches On: He starts as a rather flat and downright abusive retainer for the future Saints, later develops as a man who was honor-bound to protect Saori (while still being rather unpleasant to the saints), and ultimately was the series' comic relief.
- Dumb Muscle: He's pretty strong and will fight for Miss Saori even if the odds are stacked against him, but not too smart.
- Good Is Not Nice
- Karma Houdini: The fact that Tatsumi hasn't been tortured to death by the same Saints he abused as children is nothing short of a miracle.

- Jerkass: He brutally abused the kids at first, specially Ikki.
- Jerk with a Heart of Gold: But he genuinely cared for Saori, whom he helped raise after Mitsumasa Kido's death.
- My Master, Right or Wrong: Follows Mitsumasa Kido and later Saori Kido through the 100 orphan controversyand when Sanctuary was going after Saori for being a False Athena.
- Oh, Crap!: His reaction when he sees Ikki really survived Death Queen Island.
- Secret Keeper: Always knew that Saori was Athena, and kept his mouth shut per Kido's instructions.
- Took a Level in Kindness: He started the series being an abusive jerk, he develops a more likeable personality towards the saints as the series advances.
- Would Hurt a Child: While he probably wouldn't hit a 100% civilian kid, he sure applies lots of Corporal Punishment to the Kido Fundation boys who, in his view, stepped out of line. And then, the boy he "disciplined" the most returned...
