After the Olympian gods’ glorious victory over the titans, Mother Earth Gaea became very angry with Zeus,the King of the Gods because she felt that he had treated her sons, the Titans, unjustly.
So Gaea unified with Tartarus, the symbolization of the depths of the underworld, to create a devastating monster that would destroy Zeus and take his place. They gave the monster the name Typhoeus (Typhoon).
Typhoon had frightful features and enormous powers. The bare sight of the creature was enough for the Olympian gods to run away scared and flee to Egypt where they transformed into animals.
Only Zeus was brave enough to deal with Typhoon. Armed with thunder and lightings, he sprang from Mount Olympus and burnt down all hundred heads of the creature. Then, he tamed him and cut him into pieces and finally he sent him to the depths of the Underworld to stay forever beneath his father, the Tartarus.
