Typhon, the monstrous opponent of Zeus

Typhon was a monstrous creature and the offspring of Gaea, the Mother Earth, and Tartarus, a lower god of the Underworld. Typhon mated with Echidna, who was half woman and half snake and they created creatures that would bring terror and mischief to mankind: Orthos, a two-headed dog, Cerberus, a three-headed dog, Lernaea Hydra, a chtonic, serpent-like creature with numerous heads and Chimaira, an awful creature with the body of a goat, the tail of a snake or dragon and the head of a lion.

Typhon was part man and part beast. Below his thighs he had huge curled snakes, which when fully extended, reached his head and emitted hisses.
Typhon was the largest and strongest child of Gaea. He rose higher than all the mountains and with his head he could scrape the stars.
Typhon had wings and feathers all over his body. His hair was filthy and his eyes were flashing fire. From his huge arms sprang a hundred heads of a fierce dragon with black tongues. When Typhon stretched his arms, he was able to reach the west from one side and the east from the other.

Typhon was sought to destroy the world and to put obstacles to Zeus along his way to the Kingdom of Heaven. Everywhere Typhon went , he would spread fear and disaster.
