Gameplay

The Scylla is essentially a naval version of the Hydra, and as such can gain up to five heads, which multiplies their attack. Heads can be gained by damaging enemy military units, whether warships or land soldiers close to the water. They are quite durable and are formidable naval units. Compounding this is that most civilizations lack naval heroes, making Scyllai more difficult to defeat. Hammer ships are a serviceable replacement however. Another effective counter to the Scylla includes the use of stronger myth units like the Mummy or Vermilion Bird. The latter two deal hack damage, the Scylla's weakest armor, and additionally deal triple damage versus myth units, allowing them to make short work of a Scylla.

Mythology

"◆ Scientific Name -- Hydra Thalassa
◆ Size -- 30,000+ lbs.
◆ Diet -- Large fish, whales, sailors
A terrifying sea monster with six serpent heads and a ring of barking dogs around her waist, Scylla guarded one side of the straits of Messina, between Sicily and Italy. The dogs alerted her when a ship was passing so she could seize sailors. Scylla was originally a beautiful nymph who was transformed by the jealous sorceress Circe."

Trivia

The Hydra was originally a naval myth unit, but it was split in 2 to create the naval Scylla and the terrestrial Hydra.
The relation between Hydra and Scylla might be a reference to the uncommon misconception that Sauropods and Plesiosaurs are closely related.
The Hydra in Age of Mythology seems to be a species of carnivorous sauropod or terrestrial plesiosaur instead of the more classical serpentine depictions/descriptions of the creature. In Retold, its features are made more fantastical.
