Origin of Hydra

After the Hydra, from Greek mythology, which grew two new heads every time one of its heads was cut off. The first sense alludes to the budding method of asexual reproduction that the hydra practices, similar to growing new heads. The second sense refers to how the creature could not be killed by a swift, decisive solution (in contrast to a Gordian knot).
