1. Cerberus
By: Matthew Terven

2. Origin
Cerberus' father was Typhon, a huge dragon-like monster so horrible that even the Olympian gods ran and hid from him when he first appeared, even taking on the shape of animals to escape. It took the goddess Athena to shame and goad Zeus into confronting Typhon, and after an epic battle, burying him under Mount Aetna.
Cerberus' mother, Echidna, had the head and torso of a beautiful woman, though the lower part of her body was that of a speckled serpent. She dwelled in a cave where she ate men raw. With her husband Typhon she raised a monstrous brood which included the Hydra, the Chimaera, Orthrus the two headed hellhound, and, according to some sources, the Sphinx, as well as Cerberus.

4. Story
Cerberus is a three- headed dog that guards the underworld, allowing the dead to come in but none to come out. He was the son of Typhon and Echidna. Apart from his three heads, he also had a serpent's tail, a mane of snakes and the claws of a lion.
