!!Polaris Hilda
!!!Voiced by: MitsukoHorie (JP)
* AnnoyingLaugh: Because she's evil now!
* BladeOnAStick:
* BrainwashedAndCrazy
* BreakTheCutie: [[spoiler: As her body was taken over, her mind was trapped into the Ring of the Nibelungs and ''continuously mindraped into watching her warriors die''.]]
* CainAndAbel: With Freya, when BrainwashedAndCrazy.
* DarkIsEvil
* DarkMessiah
* EvilCostumeSwitch: From a sweet WomanInWhite to a regal WomanInBlack.
* LadyOfWar
* ManipulativeBitch
* PrincessesRule: Her parents are never seen and she governs effectively. Certainly, by averting [[GodSaveUsFromTheQueen the queen title]], being called a princess emphasize she was a kind person before being BrainwashedAndCrazy.
* VillainsOutShopping: Tends to her garden, feeds her crows, etc.
!!!Voiced by: Creator/MariaKawamura (JP)

!!Alpha Dubhe Siegfried
!!!Voiced by: Creator/AkiraKamiya (JP)
* AchillesHeel: The weak spot on his back.
* AntiVillain
* {{Badass}}: Took on all the main Bronzies simultaneously in a brutal curbstomp. [[spoiler: Shiryu almost resorted to Rozan Kōryūha but was stopped by Shura's spirit because it would have destroyed the Odin Sapphire. It was only after getting beaten brutally that Shiryu was able to find Siegfried's weakness that Seiya was able to change the tides of the battle. Even than, Siegfried still had such stamina and power that when Sorrento appeared, Siegfried not only pierced his ears in an attempt to nullify Sorrento's Dead End Symphony but was actually able to come within melee distance despite his injuries from Seiya. He even got pierced through the heart by Sorrento but Siegfried had the reserves and willpower to gather his cosmos and take Sorrento with him in a suicide attack similar to Shiryu's Rozan Koryuha. Sorrento would have died in the attack if he didn't use illusions to weaken Siegfried's grip enough to pull out his flute and play music to make Siegfried lose control and let go off him.]]
* BloodBath: His namesake from the ''Literature/{{Nibelungenlied}}'' slayed a dragon and bathed in its blood, making himself invulnerable, but at that very moment a tiny leaf falls on his back (coincidentally over his heart), preventing that bit of skin from being touched by the blood, and therefore [[AchillesHeel making that spot the only part of his body that can be dealt a mortal blow]]. Therefore, the God Warrior Siegfried inherited his destiny, invulnerability and weaknesses.
* BodyguardCrush
* TheDragon: No pun intended.
* EvilCounterpart: Blatantly intended to be Shiryu's counterpart, with the dragon-like armor and AchilesHeel.
* [[spoiler:HeelFaceTurn and RedemptionEqualsDeath]]
* NighInvulnerable
* [[spoiler:TakingYouWithMe: To Siren Sorento.]]

!!Megrez Delta Alberich
!!! Voiced By: Creator/ShigeruNakahara (JP)
* CombatPragmatist: Since he has a weak body but quite versatile powers, he uses those ''and'' his knowledge without any mercy.
* CrystalPrison: A ''nasty'' version. He can summon the "Amethyst Shield" —an attack that sends shards of amethyst flying from his body and towards the enemy, encasing him or her in a shell of translucent gemstone. If they're not freed, victims will be robbed of their lifeforce, and eventually become skeletons trapped in amethyst. And the only way to really free them is to kill Alberich himself. [[spoiler: That almost happens to Marin and later Seiya, and Shiryu has to save them both via fighting Alberich to the death.]]
* EvilGenius
* EvilRedhead
* GenreSavvy: One of his ancestors fought a Greek Saint, and Alberich uses his notes to fight the current saints. [[spoiler: And ''almost'' wins.]]
* GreenThumb
* ManipulativeBastard
* [[spoiler: NoOntologicalInertia: When he dies, his {{crystal prison}}s are dispelled.]]
* SecretKeeper: [[spoiler: Assymetric, as he was the only Asgard saint who knew Hilda was BrainwashedAndCrazy]].
* WeakButSkilled:
* YouGottaHaveBlueHair: Pink.
!!Alioth Epsilon Phenrir
!!!Voiced by: Creator/ToshihikoSeki (JP)
* AnimalMotifs: Wolf
* BreakTheCutie: his backstory. Which leads him to cross the DespairEventHorizon and become a WoobieDestroyerOfWorlds
* DontYouDarePityMe: To Shiryu

* RaisedByWolves: ''Literally''.
* WildChild

!!Mizar Zeta Cyd
!!!Voiced By: Creator/YuuMizushima (JP)
* AlwaysSomeoneBetter: For [[spoiler: Bud]].
* AnimalMotifs: Tigers

* SeparatedAtBirth
* YouGottaHaveBlueHair: Green.

* [[spoiler: CainAndAbel]]
* [[spoiler: [[FallenPrincess Fallen Prince]] ]]
* [[spoiler:FreudianExcuse]]: See [[spoiler:SeparatedAtBirth]]
* [[spoiler:MysteriousProtector: Took out Aldebaran to protect his brother. He denied it, tho.]]
* [[spoiler: SeparatedAtBirth]]
* {{Tsundere}}: Tries hard to deny that he has any feelings towards [[spoiler:Cyd.]] Goes batshit when [[spoiler: Ikki]] sees through him and uses his powers to prove it.
* YouGottaHaveBlueHair: [[spoiler:Green, just like his brother.]]
!!Benethosh Eta Mime
!!! Voiced By: Creator/YujiMitsuya (JP)
* [[spoiler: AbusiveParents: His adoptive father Volker abused him because he preferred to play the harp rather than fighting. See SelfMadeOrphan for more info]].
* {{Badass}}: Easily beaten Shun and gave a hell of a fight to Ikki that he collapsed from exhaustion afterwards.
* {{Expy}}: To Kotoza Orpheus of the first Saint Seiya movie.
* FreudianExcuse:[[spoiler:See AbusiveParents.]]
* MagicMusic
* MusicalAssassin
* [[spoiler: SelfMadeOrphan: He snaps when Volker tells him that he murdered his biological parents and kills him. Little did he know, though, that it was a part of Volker's ThanatosGambit: he wanted to both atone for the ''accidental'' killing of Mime's family '''and''' die in battle instead of his long-time illness, so he put on a JerkAssFacade for many years. In reality he always loved Mime like a son, and once risked his own life to get him medical attention, but due to his honor issues he could never show it.]]
