Hydra
the many-headed sea serpent of the Aegean
The Hydra was a colossal multi-headed sea serpent that terrorized the Aegean Sea, sinking ships and devouring sailors at the bidding of the gods. A child of Typhon and Echidna roughly the size of a small island, it was slain at last by Kratos in the service of Poseidon.
The Hydra was a colossal multi-headed sea serpent that terrorized the Aegean Sea, a beast roughly the size of a small island that sank ships and devoured sailors. A child of Typhon and Echidna, it was slain by Kratos in the service of Poseidon, the first great monster to fall in his long campaign of vengeance. (God of War (2005); God of War (novel))
The serpent of myth#
In the oldest tales of Greece the Hydra was a multi-headed serpent that dwelt in a swamp beyond the city of Lerna. It was most often said to bear nine heads, though the count changed from one telling to the next, and it was deadly poisonous. Worst of all, it could regrow its heads when they were severed, sprouting two for each one lost, and one head among them was held to be immortal. (Bibliotheca; Theogony)
That first Hydra was slain by Hercules, the son of Zeus, as the second of his labors. He cut away the heads and burned each stump so it could not grow again, and afterward dipped his arrows in the monster's poisonous blood. Its immortal head he buried and pinned beneath a great rock. The Hydra was counted among the mightiest and most terrible children of Typhon, the Father of Monsters. (Bibliotheca; Theogony)
The terror of the Aegean#
The Hydra that arose in the age of Kratos was a greater beast. In the novelisation, Athena calls it a freshly born serpent conceived by Typhon and Echidna, larger than the one Hercules had bested long before, and even Zeus is startled to see it. In the game it is a massive serpent roughly the size of a small island, its many lesser heads ruled by one dominant central head, the Hydra King; should the King fall, the whole beast dies with it. (God of War (2005); God of War (novel))
The monster challenged the dominion of Poseidon himself, wrecking ships and devouring their crews across the Aegean Sea, and so the Sea God charged Kratos with its destruction. The Hydra fell upon the Spartan's fleet as it neared Athens, and Kratos battled its heads one by one: first a lesser head that smashed up through the hull of his ship, then another that struck from above amid a flock of Harpies after gorging itself on the sailors. His final reckoning came upon the deck of another ship, where he faced the Hydra King together with two of its lesser heads and slew the beast at last by driving the ship's mast clean through the King's skull. (God of War (2005))
After the kill#
In the novelisation, the kill stirs a brief quarrel between Ares and Poseidon, with Ares suggesting that Athena had set the Hydra in the Spartan's path to trick Poseidon into empowering her chosen warrior. In the game, the Lord of the Oceans rewarded Kratos with a sliver of his own rage, a divine gift that served the Spartan well through the streets of Athens, through Pandora's Temple, and in his final reckoning with the God of War. (God of War (2005); God of War (novel))
The Hydra's hide was not forgotten. After Kratos became the God of War, the temple atop Olympus was found hung with the trophies of his past foes, and the long serpentine skin of the Hydra was displayed high behind the throne, its severed neck and head looming above all who entered. (God of War (2005))
