The Giants were 24 frightful monsters in Ancient Greece. They were conceived during the castration of the titan Uranus by his son Cronus.

The Giants were impressive creatures as tall as the mountains, with snakes on their head instead of hair and tails like that of a dragon.

Driven by the titaness Gaea, the Giants attempted to fight against the Olympian gods after their victory over the titans. The battle of the Giants against the Olympian deities is known as "Gigantomachy". During the Gigantomachy, the Giants were provoking the Olympian Gods by throwing rocks and fire to them and moving mountains, changing the flow of the rivers, drowning islands and trembling the ground.

The Olympian gods felt the need to unify in order to fight effectively against the Giants and even summoned Heracles to the battle; in the end, the Olympian gods triumphed over the Giants and imprisoned them forever in the lowest point of the underworld, the Tartarus.
