Lernean Hydra

The Hydra was a beast that dwelt in Lake Lerna.

Biography
The Hydra was born in Lake Lerna to the monsters Typhon and Echdina. Shortly after, it settled in the Spring of Amymone, where it never left. At some point during the Hydra's life, the lake cooled down and went from being a lake of molten rock to being a lake of water. In late 2018, the Hydra was raised by her first-cousin once removed, Juno, to kill Hercules. Hercules shot flaming arrows into the Hydra's lair but it did not affect it. The Hydra then fought Hercules face-to-face. Hercules cut the Hydra's heads off, but to no avail, since they just grew back in sets of two. Eventually, Hercules was able to kill the Hydra with help from his nephew Iolaus and using his golden sword to stab it.

On February 26, 2089 a giant version of the Hydra was summoned, splitting the Earth. By March 8, it had destroyed all of humanity except for Commander Cyberman Karoma.
