The Hydra is a multi-headed serpentine monster that appears in Kingdom Hearts II. It is fought at Olympus Coliseum and originally appeared in Disney's 1997 animated film Hercules.

Story

Kingdom Hearts II

Hades sends the Hydra to destroy Olympus Coliseum and kill Hercules. The hero battles and seems to defeat it, but the Hydra merely fakes its death and proceeds to destroy the Coliseum while Hercules is away. The Hydra meets its match when Sora, Donald, Goofy, Phil, Pegasus, and Megara team up to eliminate it once and for all.

Design

The Hydra is a massive, reptilian creature with dark purple skin. It has a bulky body, and it crawls using a pair of four-fingered hands with white claws. The Hydra's tail is long and thin, and each time one of its heads is cut off, two more grow back as a replacement. All of the Hydra's heads are identical; they sport long, serpentine necks, large mouths filled with white fangs, and orange eyes with slitted pupils. Spikes line each of the Hydra's heads and necks. In the Japanese version of Kingdom Hearts II, the Hydra spews green blood when one of its heads is cut off. In other versions of the game, the blood is changed to purple smoke except in one cutscene.

Strategy

When fighting the Hydra, in addition to having Donald and Goofy in the party, Sora will have Phil, Megara, and Pegasus for support. Phil tosses urns that can stun the Hydra, Meg gives Sora much-needed HP, MP, and Drive orbs when he gets close to her, and Pegasus allows Sora to use the Pegasus Run reaction command.

Sora must first attack the Hydra's main head. When the Hydra's HP is depleted to a certain point, he must use the Vanquish reaction command to remove the head, ending the first phase. After this is done, the Hydra buries its head in the sand, causing three more heads to sprout out from underground in various locations, starting the second phase. By teaming up with Phil, Sora can use the Phil One-Two and Urninator reaction commands to immobilize them. Sora must defeat each of these heads and use Vanquish on them before they awaken.

In the third and final phase of this battle, the Hydra pulls its neck out of the ground and reveals a set of seven heads. Sora can team up with Pegasus and use the Pegasus Run reaction command to strike each head. Once the Hydra's HP has been depleted to 1, Sora need only use the Vanquish reaction command a final time to finish the monster off.

If the Hydra manages to defeat Sora, the option to revive him using King Mickey may become available. Victory grants Sora access to the Thunder spell, as well as the Hero's Crest Keyblade.

Origin

The Hydra first appeared in Disney's 1997 animated film, Hercules. It is based on the Lernaean Hydra, a serpent-like water monster in Greek mythology. According to myth, the Hydra's defeat was one of the Labours of Hercules.

In the film, Hades ordered his minions, Pain and Panic, to disguise themselves as little boys and pretend to get trapped under a large boulder. He then used Megara to lure Hercules to their location. Hercules removed the boulder to save the "boys," but in doing so, he accidentally unleashed the Hydra. After a brief struggle, the monster managed to swallow Hercules whole. The hero escaped death, however, by cutting off the Hydra's head from the inside, which seemingly killed the beast.

Before Hercules could celebrate his victory over the Hydra, the creature's corpse came back to life and sprouted three more heads. Hercules resumed his battle with the Hydra, and as the fight continued, he came to realize the more heads he cut off, the more grew back to take their place. Eventually, the Hydra managed to pin Hercules against the side of a cliff. Faced again with elimination, the hero used his god-like strength to cause a rockslide, whereupon the Hydra is crushed to death by an avalanche of falling boulders.
