Scylla Scale

The Scylla Scale (スキュラスケイル, Sukyura Sukeiru) is the Scale of the Marine General Io, Guardian of the South Pacific Pillar, in Saint Seiya. It is the Scale of a Marine General, the Gold Saint equivalent.

Triton's Daughter?
In ancient myth, Scylla was a horrifying monster that had the upper body of a beautiful maiden, but her lower body was comprised of six heads, each looking to devour a man who dared sail between her and Charybdis. Odysseus lost six of his crew in one strike, while trying to pass this monstrous creature.

Scylla - Truly Beauty and the Beast
Io first appeared in volume 15 of Saint Seiya as the Marine General who is protecting the South Pacific Pillar. He was the second of the Marine Generals to be challenged by a Saint in order to protect his Pillar. He defended his Pillar against Shun and his Andromeda Chains. Shun's Rolling Defense quickly proved useless as each of the six heads of Scylla struck in a way he couldn't stop with his normal defense. But, Shun quickly showed off six new techniques, each stopping his attacks and crushing that portion of his Scale. He attempted to stop Shun with a final technique, but he was restrained, and his broken Scale was last seen as he leaped into the way of the Libra Twin Rods, failing to stop Shun from destroying his Pillar.

Special Abilities of the Scylla Scale
The Scylla Scale stays true to it's namesake, as there are six weapons attached to the Scale, each allowing for a special attack to be used. Each is symbolic for the particular animal the head was: The Eagle, the Wolf, the Queen Bee, the Serpent, The Vampire Bat, and the Grizzly Bear

Techniques used by Scylla Mariners
Io uses seven major techniques during his fight with Shun.
 * Eagle Clutch (イーグルクラッチ, Īguru Kuracchi): is an offensive technique used by Io when battling Shun. Io uses one of the Eagle's Claws on his Scale's arms, along with his cosmo, to cut at a foe sharply. If both of the Eagle's Claws are destroyed, he is unable to perform this technique.
 * Wolf's Fang (ウルフズファング, Urufuzu Fangu): is an offensive technique used by Io when battling Shun. Io uses the Wolf's Fangs on his Scale's helm, along with his cosmo, to inflict a biting attack on the enemy. If the Wolf's Fangs are destroyed, he is unable to perform this technique.
 * Queen Bee's Stinger (クインビーズスティンガー, Kuinbīzu Sutingā): is an offensive technique used by Io when battling Shun. Io uses the Queen Bee's Stinger on his Scale's right hand, along with his cosmo, to inflict a painful stinging strike on the enemy. If the Queen Bee's Stinger is destroyed, he is unable to perform this technique.
 * Serpent Strangler (サーパントストラングラー, Sāpanto Sutorangurā): is an offensive technique used by Io when battling Shun. Io uses the Serpent's Fangs on his Scale's left hand, along with his cosmo, to constrict the foe in a painful manner. If the Serpent's Fangs are destroyed, he is unable to perform this technique.
 * Vampire Inhale (バンパイアインヘイル, Banpaia Inheiru): is an offensive technique used by Io when battling Shun. Io uses the Bat's Wings on his Scale's back, along with his cosmo, to perform a blood draining attack that is hard to defend against due to it's erratic, bat-like movements. If the Bat's Wings are destroyed, he is unable to perform this technique.
 * Grizzly Slap (グリズリースラップ, Gurizurī Surappu): is an offensive technique used by Io when battling Shun. Io uses the Bear's Body (which comprises his Scale's breastplate), along with his cosmo, to perform a powerful upward slap that sends the foe flying into the air. If the Bear's Body is destroyed, he is unable to perform this technique.
 * Big Tornado (ビッグトルネード, Biggu Torunēdo): is the ultimate offensive technique used by Io, which he used on Shun. Io used this technique only after all six of his Scylla Weapons had been destroyed. Curving his fingers, he holds his hands parallel from one another, and twists them, releasing his cosmo in a great whirl of energy, throwing his foe around like a whirlpool, or the tornado it is named after.
