Mariners

The 7 Marina General (海将軍 ジェネラル Kai Shōgun Generaru) are the strongest among Poseidon's Marina army and are devoted to the protection of the 7 Sea Pillars that sustain the seven seas. Their fighting strength is said to be on par with the Gold Saints if not above them, but their Scales, supposed to equal the endurance of a Gold Cloth, have proven to be more fragile. This can be caused by the fact that Poseidon's army has awakened too early because of Kanon's plot and hasn't be able to show it's full power. This is somewhat hinted by the Official Encyclopedia and could also explain how the Saints managed to contain Poseidon's unlimited might, but there isn't a clear confirmation. They represent some famous sea monsters of the myth and the Scales are shaped on them. They are all manipulated by Kanon that plans to use their strength to decimate the Saints to assume power, so he make them believe that it's Poseidon's plan to purify the rotten humanity to found a new era of peace. Although being Saint's enemies, they are proven to be honorous heroes capable to die for their cause. Marina Generals has been the first strong enemies the Saints had to fight in history, during the Myth Era and Clothes has been created to oppose the power of the Scales, expecially the 7 Scales of the Generals. It's easy to guess that the whole Gold Saints order has been created taking inspiration from the 7 Generals, just like the 12 Gold Cloths shaped to oppose the 7 Scales. The 7 Generals have a symbol like the zodiac symbol of the Gold Saints sculped at the top of the Zodiac Temples. Those symbols can be noted sculpted on the 7 Pillars that are protected by the Generals with the same effort as the Zodiac Temples of Sanctuary. Although the Generals don't fear even the power of the Gold Saints as shown by Siren Sorrento that easily handles the might of Taurus Aldebaran in the manga and Dubhe Alpha Siegfried in the anime, they are defeated by the Bronze Saint rising their Seventh Sense to the extreme extent and aided by the true power of the Clothes reborn with the golden blood and granted an endurance similar to the Gold Clothes.
