Characters: Saint Seiya Mariners

Mermaid Thetis

Voiced By: Hiromi Tsuru (JP)

  • Affably Evil: Very polite and soft-spoken, until she fights.
  • But Now I Must Go: Anime-only, when she changed back to her mermaid form and leaves.
  • Cry Cute: "Milord Poseidon... now you're back to being Young Julian Solo..."
  • Dark Chick: While she does have the fighting abilities, she's more of a messenger than a frontline fighter.
  • Happily Ever After: In the end of the Poseidon Arc in the manga, Thetis changed back into a fish. Jullian/Poseidon comes back and finds her dead fish body and holds it gently in his hands. In the anime, it was happier where Thetis changes into a mermaid and you can see her leaping in and out of the water with the good guys staring at the sunset.
  • Designated Girl Fight: Though she does give Shaina quite a run for her money.
  • DistractedbytheSexy: Extreme aversion. Kiki openly insults her as an "ugly fish squid creature".
  • Lady of War
  • Meaningful Name: Thetis is a goddess of the sea and leader of the Nereids (sea nymphs) in Greek Mythology. As well as the mother of Achilles.
  • Our Mermaids Are Different
  • Perky Female Minion
  • Mythical Name: After one of the Twelve Titans from Greek mythology. The mother of the rivers, springs, streams, fountains and clouds.

Scylla Io

Voiced By: Issei Futamata (JP), Gerardo Reyero (Latin America)

  • Defiant to the End : Prefers to go down fighting towards Shun despite being bound in chains, trying to block Shun's direct attack (via Libra Cloth's weapons) on the pillar he protected. Shun is very impressed at his Undying Loyalty to Poseidon and expresses sadness at his passing.
  • The Beastmaster: His power is to summon the abilities of six creatures.
  • Mythological Name: From Io the sea nymph in Greek Mythology.
  • You Gotta Have Pink Hair
  • Real Men Wear Pink: Gave Shun a very hard fight and died awesomely.
  • Senseless Sacrifice: Tries to keep Shun from destroying his pillar by shielding his body. Unfortunately, he never had a chance due to him being bounded up and the pillar itself being too big to protect all of it.

  • BADASS: After his Heel-Face Turn and becoming the Gemini Saint, in the Hades Arc he singlehandedly kills more Specters than half the Gold Saints combined. Only Shaka and Dohko can compare in kill counts. He even has the honor of being the only Gold Saint to kill a Judge in the classic series.
  • Cain and Abel: He's Saga's twin brother.
  • Dragon with an Agenda: No pun intended. He tries to use Poseidon to rule the world.
  • Heel-Face Turn: He becomes the Gemini Saint after Saga.
  • Genius Bruiser: He is responsible for most of the conflicts within the classic series. He manipulated Poseidon into doing starting his next holy war against Athena earlier than scheduled, awakened the evil in Saga's heart and drove him into insanity, and ALMOST SUCCEEDED in gaining world domination until he made the fatal error of underestimating the main Bronzies.
  • Evil Twin: To Saga.
  • The Man Behind the Man.
