Cyclops

The Cyclops were one-eyed, viscious feral monsters with no use for kindness, manners, and laws. Many of the cyclops were shepherds out of necessity as they needed to eat and if they wandered to close to a human village, the villagers would come together to chase the cyclops away and sometimes even kill them. Villagers were very vigilant and quick to act if a cyclops was spotted because the monsters were known for preferring to eat humans, especially children. If a cyclops came across a human or a group of humans, it would scoop them up in its large hands and carry them back to its cave to eat over time.

Chimaera

Chimaeras were one of the most monstrous female monsters, as they were a combination of three different animals. A chimaera would generally have the head of a lion, the tail of a mighty serpent, and the body of a goat. Chimaeras were capable of breathing fire, had sharp claws, and a hunter’s instinct. These monsters would attack any human that they came across, regardless of age or gender. They were also fully capable of destroying entire villages, burning them to ash.

Manticore

Manticores were similar to chimaeras in that they were a combination of more than one creature. A manticore would have the body of a lion, a scorpion’s tail, the wings of a bat, and the head of a man. The fact that its head was human allowed the manticore to learn and mimic human speech, which allowed the monster to lure human prey to it by screaming for help and then pouncing on the human that came to help it. A manticore’s favorite food was human flesh and organs.

 Hydra

The hydra was a giant serpent creature with huge poisonous snakes for heads. Each time one of the snakeheads was cut off, two more would regenerate to take the place of the lost head. The regeneration of heads made the hydra a fearsome monster as the only way to kill it was to chop off all the heads at the same time. This was a difficult feat due to the fact that the hydra’s breath was poisonous; a single inhalation would lead to sudden paralysis, and then a slow death by being swallowed whole by the hydra.

Cerberus

Cerberus was also known as the Hound of Hades as Cerberus served the Lord of the Underworld in keeping the dead from entering the world of the living. Cerberus was a giant three-headed black dog that was the size of five elephants combined. Cerberus would tear any dead soul that tried to leave the Underworld into pieces and would stop any living soul from entering the Underworld without Hades's permission.

Telchines

The telchines were a race of serpentine beings with the head of a dog, flippers of a fish, and the body of a water snake. These monsters were three times the size of a human and they were capable of controlling hail, rain, and snow. They were also able to shapeshift into any form they desired from which they were capable of producing a poison that could kill any living thing. These monsters slaughtered villages in revenge for a perceived slight from Mount Olympus.
