Not much else is known about the Hydra.
In Greek mythology, the Lernaean Hydra was an ancient serpent-like water monster with reptilian traits. It possessed many heads — and for each head cut off it grew two more. The Hydra was one of the offsprings of Typhon and Echidna, both of whom were noisome offspring of the earth goddess Gaia.
