Hydra is a jet appearing in Grand Theft Auto: San Andreas.
Relation to Myths
In Greek mythology, the Hydra was an ancient serpent-like water monster with reptilian traits. It possessed many heads, the poets mention more heads than the vase-painters could paint, and for each head cut off it grew two more Cut off one head, Two more shall take its place. It had poisonous breath and blood so virulent that even its tracks were deadly. The Hydra of Lerna was killed by Heracles, as the second of his Twelve Labours. Its lair was the lake of Lerna in the Argolid, though archaeology has borne out the myth that the sacred site was older even than the Mycenaean city of Argos, since Lerna was the site of the myth of the Danaids. Beneath the waters was an entrance to the Underworld, and the Hydra was its guardian. Surprisingly, a Ghost Hydra can also be found within the game.
