List of Saint Seiya antagonists
The antagonic characters appear as various deities from Greek mythology, who rule over the realms that form Earth, and their servants who form part of their armies created to wage war against Athena, the protector of the Earth realm. In addition, several factions aren't presented as soldiers of these armies, but as organizations who pursue their own ends.
The Black Saints (暗黒聖闘士（ブラックセイント） Burakku Seinto). alternatively spelled as Ankoku Saint (あんこくセイント Ankoku Seinto) in the anime, appear as servants of the Bronze Saint Phoenix Ikki, on his quest to kill all the Bronze Saints. The Black Saints are former Saints who were stripped from their title and Cloth for using their strength for personal gain, turning to a life of crime and violence. All of them trained in Death Queen Island along with several sons from Mitsumasa Kido, but most of them died. Although there is a Black Saint counterpart for each one of the 88 constellations, Kurumada featured prominently only four in his manga, the dark equivalents of the protagonists: Black Pegasus (ブラックペガサス Burakku Pegasasu) voiced by Shigeru Nakahara, Black Andromeda (ブラックアンドロメダ Burakku Andoromeda) voiced by Kaneto Shiozawa, Black Dragon (ブラックドラゴン Burakku Doragon) voiced by Ken Yamaguchi and Black Swan (ブラックスワン Burakku Suwan) voiced by Kazumi Tanaka.
They were regarded as the most powerful among the Black Saints and were collectively known as The Black Four (暗黒四天王（ブラックフォー） Burakku Fō). Their Cloths and techniques are counterparts to the ones from Pegasus Seiya, Dragon Shiryū, Andromeda Shun and Cygnus Hyōga. Although, there is only one counterpart of each Cloth, in the manga the Black Dragon Saint has a blind brother that helps him to fight. Additionally, there are also several Black Phoenix Saints, who refer to themselves as Ikki's shadows, although in the anime one of them appears as the strongest one. The four Black Saints are defeated by their equivalents, and in the manga they are later killed by the Silver Saints, who were meant to kill the Bronze Saints, but mistook them due to an illusion created by Aries Mu.
Additionally, the Black Four were featured in the anime-inspired printed sidestory "Nebula Chain – The bond of brothers", in which they were given names, Black Pegasus was known as Kenuma (ケヌマ Kenuma), Black Swan was called Jid (ジド Jido), Black Dragon was named Shinadekuro (シナデクロ Shinadekuro) and Black Phoenix was called Ritahoa (リタホア Ritahoa), leaving Black Andromeda unnamed.

The Blue Warriors (氷戦士（ブルーウォリアー） Burū Woriā, lit. "Ice Warrior") are an order of powerful warriors from the ice lands of Bluegrad (known as Sinigrad in English publication), who also draw their strength from their Cosmo. Their order was formed centuries ago by mighty warriors who, in the same way as Athena's Saints, were capable of rending the skies with their fists and splitting the earth with their kicks. The Blue Warriors were led by Alexer (アレクサー Arekusā), prince of Bluegrad, and protected their homeland against any menaces. They were presented by Kurumada in vol.13 of his manga, in the short story arc he dedicated to Hyōga, "Kōri no Kuni no Natassia Hen" (The Chapter of Natassia, from the Lands of Ice). Their only known technique is "Blue Impulse".
The Marine Realm
In the same way Athena has Saints, Poseidon has an army that has assisted him since the age of myth, the Mariners (海闘士 Marīna, lit. "Sea Fighter"). With Poseidon's Undersea Temple serving as its base in the Marine Realm (海界 Kaikai), it is formed by hundreds of low-ranking soldiers and commanded by seven powerful warriors known as Generals, whose Cosmo rivals that of a Gold Saint. These Generals don armors called Scales (鱗衣 Sukeiru, lit. "Scale Mantle"), which are said to be as resilient as the Gold Cloths and are modeled after marine creatures of legend. Their duty is to defend the Mammoth Pillars (巨大柱 Manmosu Pirā) of the seven oceans (North & South Atlantic, North & South Pacific, Arctic, Antarctic, and Indian) that safeguard the Undersea Temple. The strongest pillar, the Main Breadwinner (メインブレドウィナ Mein Buredowina), is defended by Poseidon himself.
- Sea King Poseidon (海皇ポセイドン Kaiō Poseidon)
- Voiced by: Osamu Saka, Keiichi Nanba (Julian Solo)
- As in Greek mythology, the Greek god Poseidon is the ruler of the seas, brother of Hades and Zeus. In Kurumada's story, he reincarnates on Earth by taking the body of a chosen member of the Solo family as a vessel for his soul. This Greek family is one of the wealthiest in the world and, enjoying Poseidon's blessing, has held hegemony over the seas for millennia. In the 20th century, the god takes the body of the family's young heir, a teenager named Julian Solo (ジュリアン・ソロ Jurian Soro), and strikes the Earth with incessant rains to cleanse it of humans, whom he considers evil and unworthy of the blessings of the gods. He wishes to build an utopian society on top of the ruins once all humans are eradicated and to exact revenge on Athena for having sealed his soul after their last battle, two thousand years before. To this end, he holds Athena hostage in his Undersea Temple with the help of his army. He is ultimately sealed by Athena in her amphora, but later proves that he is not an evil deity, as he awakens briefly to help the Bronze Saints fight Hypnos and Thanatos in the Hades arc by sending them the Gold Cloths.
- Mermaid Thetis (人魚姫（マーメイド）のテティス Māmeido no Tetisu)
- Voiced by: Hiromi Tsuru
- A loyal servant of Poseidon, bound to him by a debt of life. Thetis was saved by Julian Solo when he was a little boy. She was then a beautiful fish, stranded on a beach, and Julian tossed her back into the sea. During Poseidon's kidnapping of Athena, she served as mediator between the factions of Poseidon and Athena. Thetis is not one of the Mariner Generals, but a middle-ranking soldier, as she is superior to the Mariner rankless soldiers, but subordinate to the Mariner Generals. She was unable to assist the Mariner Generals due to her defeat by Ophiuchus Shaina. The Saint spared her life and Thetis ended rescuing Julian Solo from the collapse of the Underwater Sanctuary after Athena removed Poseidon's soul from him. Thetis turned back into a fish as she died and Julian, upon finding it, let it back into the ocean, finally laying her to rest.
- Rankless Mariners (雑兵の海闘士（マリーナ） Zōhyō no Marīna)
- The vast majority of Poseidon's army, counted by the thousands. Unlike Athena's and Hades' rankless soldiers, the Rankless Mariners possess mastery over Cosmo to some degree, as they wield low-level superhuman strength and also wear weaker versions of the Scale armors worn by their superiors, the Mariner Generals.
The seven most powerful warriors of Poseidon and commander Generals (海将軍（ジェネラル） Jeneraru) of his army. Endowed with might that equals or surpasses that of a Gold Saint, the Mariner Generals wear the Scale armors, said to be as resilient as the Gold Cloths.

- Scylla Io (スキュラのイオ Sukyura no Io)
- Voiced by: Issei Futamata
- The devoted guardian of the South Pacific Ocean Pillar. Upon Andromeda Shun's arrival, Io tried to deceive the Saint with an illusion of a maiden.

Io used attacks that matched the six creatures that made up the Scylla beast from Greek myth, but, after withstanding Scylla's attacks, Shun was able to successfully counterattack each of them. Shun spared Io, but as he prepared to destroy the Pillar with the weapons of the Libra Cloth, Io, compelled by his adamant devotion to Poseidon, jumped in front of the attack to stop it. Io's attempt failed and he was thus killed.
- Chrysaor Krishna (クリュサオルのクリシュナ Kuryusaoru no Kurishuna)
- Voiced by: Masaharu Sato
- Krishna was the guardian of the Indian Ocean Mammoth Pillar. He employed a golden lance and spiritual power derived from the Kundalini trascendental forces. Dragon Shiryū challenged the Chrysaor Mariner. The lance proved to be too much for the Dragon Saint, until he remembered that the spirit of Excalibur laid in his right arm, handed down to him by Shura. Thus he was able to break the lance in half. Krishna was not fazed and meditated to flare his Cosmo to the maximum, unleashing a final attack on Shiryū. The combat ended with Dragon Saint hitting Krishna's Chakra points while losing his sight from Krishna's attack. Krishna was defeated and Shiryū destroyed the Pillar with the help of Kiki.

- Voiced by: Keaton Yamada
- Known as the "hunter of hearts" and regarded as the most fearsome Mariner, Caça was responsible for the Antarctic Ocean Mammoth Pillar. He protected it by means of treachery and deception, as he was able to draw from a person's most cherished feelings and turn them against them by masquerading as someone they held dear. He took out Pegasus Seiya, Cygnus Hyōga and Andromeda Shun with his illusions. However, when Phoenix Ikki first arrived, Caça was unable to sense any treasured feelings. He only found one enclosed deep in the Saint's heart. This, however, angered the Phoenix Saint, leading to the Lyumnades Mariner's death.
- Kraken Isaac (クラーケンのアイザック Kurāken no Aizakku)
- Voiced by: Ryusei Nakao

There he became a Mariner and guardian of the Mammoth Pillar of the Arctic Ocean. Upon the Saints' attack on the Underwater Sanctuary, he came face to face with Hyōga and blamed him for everything that had gone wrong years ago. Cygnus Hyōga eventually overpowered him after unsuccessfully trying to repent to his old friend. As he died in Hyōga's arms, Isaac congratulated his friend for becoming so powerful.
- Siren Sorrento (海魔女（セイレーン）のソレント Seirēn no Sorento)
- Voiced by: Yoku Shioya

During Poseidon's cleansing of the world, the Siren Mariner was ordered to kill the four Bronze Saints, Seiya, Hyōga, Shun and Shiryū, who were comatose in a hospital. He met with Taurus Aldebaran's resistance, but Athena interrupted the battle, ordering Sorrento to take her to Poseidon. He obliged and returned to the Underwater Sanctuary. Later, when the Saints invaded, he faced Andromeda Shun, who after a fierce fight managed to defeat Sorrento and destroy his pillar. During the events, Sorrento became suspicious of the Sea Dragon Mariner, concluding that Poseidon's resurrection and the ensuing war were the result of Sea Dragon's ambition and not Poseidon's. These suspicions were confirmed during Phoenix Ikki's battle against Sea Dragon Kanon. After Athena sealed Poseidon's soul and returned to the surface, Sorrento did the same and sought out Julian Solo, the former host of Poseidon's soul. Together they decided to travel the world and help the people that suffered in the catastrophe caused by Poseidon. Sorrento was still with Julian when Poseidon reawakened and sent help to the Bronze Saints in the battle in Elysion.

Both Hades and Athena have engaged each other in a long standing conflict for domination of Earth, that spans across millennia, sparking bloody Holy Wars in the ages of myth, the 15th, 18th and 20th centuries. Hades, whose beautiful body is the spawn of the union between Cronus and Rhea, was subjected to a traumatic experience in the ages of myth, when he was gravely wounded by Pegasus Seiya's incarnation in that era. Thus, Hades decided to put his true body to rest in the unreachable Elysion, until his dominion over Earth is secured. To be able to incarnate, Hades then chose the body of the purest human in the era of his return, as a host for his divine soul, being Alone his chosen vessel during his incarnation in 1747, and Andromeda Shun in 1990. The god of the Underworld was defeated by Athena and her Saints in each of his incarnations, at the high cost of the Saints' lives and havoc over the land. Particularly bloody have been the encounters between the deities in the 18th and 20th century. During the latter, Hades retreats to shelter himself in the Underworld, believing himself safe from Athena and her Saints, who devise a way to invade Underworld. Determined to achieve domination of Earth whatever the cost, Hades unleashes the Greatest Eclipse phenomenon on Earth, which would conceal the sun, turning the planet in a gelid graveyard and exterminating all life. Against all odds, Hades is later rejected by his chosen vessel Shun, and retreats to the Elysion and captures Athena and places her in the lethal Great Amphora, assuming the Saints would never be able to trespass the Wailing Wall in time to save their goddess' life. He is proven wrong by the Saints' tenacity, and the ruler of the Underworld is forced to revive his true body, dormant for millennia since the ages of myth, and engage the Saints in a final duel to the death, during which Hades is shocked to encounter his feared enemy from the ages of myth reincarnated in Pegasus Seiya. Athena, freed from the Amphora joins her Saints in the battle, and after a brief but costly battle, against all odds, Hades is finally defeated. The mortal world is saved from the Greatest Eclipse and the Elysium collapses, but Seiya was also defeated in the battle, being pierced in the heart by Hades' sword and put into a curse which kept him in a catatonic state.

This did however backfire as Seiya rose to a new level of power, resurrecting his God Cloth and soon defeated the god.

- Voice Actor: Issei Futamata

In his effort to stop Pegasus Seiya he was however halted by the other Bronze Saints as they each successfully resurrected their God Cloths and severely wounded the god. Hypnos lived long enough to sense the moment when Hades true body was awakened, but succumbed to his injuries soon after.

Trying to engage Mu in combat, he was ignored by the latter, who considered Niobe already dead. Niobe was then completely torn apart by the delayed effect of Aldebaran's Great Horn.
- Earthly Hiding Star, Worm Raimi (地伏星ワームのライミ Chifukusei Wāmu no Raimi)
- Voice Actor: Kazuya Nakai
- Raimi was one of the 17 Specters sent in secret by Wyvern Rhadamanthys to attack Athena's stronghold, Sanctuary. When the group reached the Temple of Leo, five of them were immediately killed by its guardian, Leo Aiolia. As the other Specters continued their attack, Raimi saw this as an opening and entangled the Gold Saint, claiming him to be his victim. However, the Specter underestimated Aiolia and after sending the other Specters to the next temple, Raimi was soon killed by the Leo Gold Saint
- The Worm Specter in the 18th century also appears briefly in Next Dimension, battling against Leo Kaiser, whom he is unable to defeat, and the Specter is ultimately defeated by Cancer Deathtoll with an humilliating attack. The name of the Worm Specter in that era was not revealed by Kurumada, although he wears the same Surplice and his appearance is identical to Raimi's.
- Earthly Strange Star, Frog Zelos (地奇星フログのゼーロス Chikisei Furogu no Zērosu)
- Voice Actor: Bin Shimada
- Zelos was the one who sent the 17 Specters to Athena's Sanctuary by the order of Wyvern Rhadamanthys. He acted as the messenger of the events in the Sanctuary to Rhadamanthys, even though he questioned Wyvern's decision due to Pandora's wrath. As the revived Gold Saints came to Hades castle with Athena's body, Zelos was there to greet them. The Gold Saints disregarded him and Aquarius Camus pushed him aside with his cold winds. Thus, when the revived Saints lay dying on the floor due to their time limit, the Specter took out his frustration on Camus. This would prove not in his favor as Cygnus Hyōga and the other Bronze Saints burst through the ceiling. With his own cold blast, the Cygnus Saint hastily killed the Frog Specter.
- Earthly Strange Star, Frog Meehan (地奇星フログのミーヤン Chikisei Furogu no Mīyan)

- An unidentified character who briefly appears before Crateris Suikyō, conveying Hades' offer to become one of the three magnates of the Underworld and save his younger brother Suishō's life, in exchange of loyalty to him. Kurumada has yet to reveal his name and star, as the only confirmed fact is the mythical being represented by his Surplice.
- Unnamed Specters

- 23 new Specters were added to the Saint Seiya universe by Kurumada in Next Dimension, although they were not named and their destiny stars remain to be revealed: 9 of them were part of Garuda Suikyō's cadre invading Sanctuary, and other 7 appear freeing Cancer Deathtoll in the Hill to the Land of Spirits. One new Specter appears among the cadre killed by Phoenix Ikki and Deathtoll, the rest are Specters from Kurumada's original manga appearing in their 18th century incarnation, and a few Skeleton soldiers. 6 new Specters appear in Griffon Vermeer's cadre invading Sanctuary.
- Hades' Skeletons (冥王ハーデス軍の雑兵スケルトン Meiō Hādesu Gun no Zōhyō Sukeruton)
- The rankless soldiers from Hades' army, wearing weaker versions of the Specter Surplices, and armed often with sickles, as they have no mastery over Cosmo. One of them, the Rankless Soldier Skeleton Marchino (雑兵スケルトンのマルキーノ Zōhyō Sukeruton no Marukīno), is briefly featured prominently and as a comic relief, leading Pegasus Seiya and Andromeda Shun to the Silent Tribunal, where he dies after offending Balron René. His voice was provided by Naoki Tatsuta.
The Heavenly Realm
The Angels (天闘士（エンジェル） Enjeru, lit. "Heavenly Fighters") are Powerful warriors from the Heavenly Realm (天界 Tenkai), servants of the Olympic gods, and wearers of the Glory (天衣（グローリー） Gurōrī, lit. "Heavenly Mantle") armors. To date, Kurumada has shown them as loyal to the moon goddess Artemis.
- Angel Tōma (天闘士（エンジェル）・斗馬 Enjeru Tōma)
- Voice Actor: Hikaru Midorikawa

His background was further revealed in the Tenkai-Hen Josō ~Overture~ theatrical feature and its introductory short comic book, authored by Kurumada, in both of which he appears as an Angel. His movie incarnation now remains out of the Saint Seiya canon, as he is now being featured in the latest installments of Saint Seiya: Next Dimension, in which he also appears as an Angel, chained in the prison of the moon and is released by Callisto, with the mission to assassinate Pegasus Seiya, his reward being his freedom if he fulfills it. His Glory is specifically named Sleep Angel Version Glory (スリープ・エンジェル・バーション天衣 Surīpu Enjeru Bāshon Gurōrī). His mission comes to an halt due to the intervention of Cygnus Hyōga and Eagle Marin, whom he finds familiar. Although Kurumada has retained many of his original traits, whether he will remain the same character portrayed in the film or a completely new rendition, is yet to be revealed.
The Lunar Realm
The Lunar Realm (月の世界 Tsuki no Sekai) is ruled by the beautiful goddess Artemis, older sister to Athena and younger sister of Apollon. Although Artemis initially shows hostility to Athena, she later offers her assistance. Despite this, Artemis' servants plot secretly to kill Athena and her Saints. Additionally, the Angels, the warriors of the Heavenly Realm, seem to have pledged allegiance to Artemis.
- Moon Goddess Artemis (月の女神・アルテミス Tsuki no Megami Arutemisu)
- The beautiful goddess of the moon, and elder sister to Athena. The goddess is initially hostile to her sister due to her battles with Hades and Poseidon. Though she reveals to Athena that the only way to remove Hades' curse from Seiya's body is to travel back in time with the help of Chronos. Her base of operations is the temple of the moon, situated on the slopes of Mount Olympus. This temple is protected by numerous soldiers called "Satellites".
- Handmaid Callisto (侍女・カリスト Jijo Karisuto)
- Servant of Artemis and high-ranking officer among the Satellites, the personal guard of Artemis. She is very caring of her goddess, and will resort to anything for her safety. Callisto initially warns the goddess Athena not to visit Artemis because she is angered by the goddess of war's past conflicts. Athena refuses, so Callisto allows her to pass. She still deems her very risky to Artemis so she later sends Lascomoune, captain of the Satellites, to kill Athena. After her failure, she resorts to sending the much more powerful warrior, Tōma the Angel, to kill Athena's Saints, releasing him from the Lunar Prison. In chapter 30 of Saint Seiya Next Dimension, during Tōma's reintroduction to the canon, Callisto replaces the shady, unidentified character that freed the Angel, in Kurumada's short introductory comic book for the now apocryphal ~Overture~ film.
- Moon Witch Hecate (月の魔女ヘカーテ Tsuki no Majo Hekāte)
- The elderly witch of the moon. Kurumada based her on the mythological persona Hecate. She tricks Athena into cutting off her hair by means of an illusion of multiple pathways to the temple of the moon. She makes a brew with Athena's hair which restores her youth, becoming a young girl again. She then guides Athena to Chronos who in turn punishes her, turning her body into dust. Later, she resurfaces unharmed, as she was able to survive Chronos' assault. The young Hecate displays a childish and whimsical behavior, and has exhibited the ability to transform into a crow. Sometime after Athena's departure, she assists the Saints in reaching Athena's garland, which leads them to the era of the past Holy War. Hecate is a thousand years old, and it is keeper of the road leading to the temple of Artemis, situated on the slopes of Olympus, which begins with a very large stone column, surmounted by a crescent moon.
