Scythian Dracaena

Scythian Dracanae (Ancient Greek: Σκύθες Δράκαινα) are commonly seen as female reptilian monsters with some human features, prominently shown as soldiers for Kronos, in the Titan Army. They are known to always challenge Mount Olympus and its protectors.

The Sea of Monsters
Percy first encounters Scythian Dracanae in his second adventure aboard the Princess Andromeda. These female reptilian 'menaces' prove to be ominous new foes.

The Titan's Curse
The Dracanae, among other monsters, attempt a fruitless attack on Percy Jackson and his friends soon after defeating Atlas on his mountain, Mount Tamalpais. Dr. Chase intervenes with Celestial Bronze bullets being shot from his Sopwith Camel.

The Battle of the Labyrinth
Percy is forced to fight various villains in Antaeus' lair, the first of which being a dracanae. Percy almost immediately kills it, much to Antaeus' disapproval. They also show up in the actual Battle of the Labyrinth as one of the main types of soldiers.

The Last Olympian
The dracanae appear again as one of the main soldiers in Kronos army attacking Manhattan. They also serve as Kronos' bodyguards in some instances and one is even crushed by a flagpole carrying Brazil's colors outside the United Nations Building. Their leader, Queen Sess, appears but is shot with an arrow by Chiron.

The Lost Hero
Jason remembers armies of Scythian dracanae on Mt. Othrys when he and the Legion scaled the mountain.

Appearance
The Scythian dracanae are described as humanoid females with twin serpent trunks instead of legs. They have been described as "Dragon women" or "Snake women." Their walk has been described as "a combination of walking and slithering like walking on living skis" by Percy. When they talk, they hiss the letter S when they say it.

Notable Dracanae
Only one dracana in the entire series has been named: Queen Sess.
