Greek mythology depicts Giants as long-haired giants. The Giants were the sons of the goddess Gaia and were born from drops of the blood of the god Uranus.
Giants are most often depicted in human form, but later they were also attributed with snake bodies, wings, lion heads and claws.
These giants were immensely powerful and did not recognize the rule of Zeus, to the point of rebelling against Zeus and all the Olympian gods. The reason for their rebellion was that the gods had imprisoned the Titans. It was for this act that Gaia sent the Giants against them. The Giants were not afraid of the Olympians because they were invulnerable to the magic plant. So the gods summoned Heracles to help them. He was the first to kill the strongest of the Giants, Alcyoneus, using a poisoned arrow in combination with throwing the Giant over the boundaries of the land in which the Giant was immortal. Subsequently, Hephaestus killed the giant Clytius with red-hot iron, Athena killed the giant Enkelado with the entire island of Sicily, and Poseidon killed the giant Polybothus with a piece of the island. All the others were struck down by Zeus with lightning and then slaughtered by Heracles.
