Echidna (mythology)

Echidna ("she viper") was a female monster in Greek mythology, usually considered offspring of Uranus and Gaia, or sometimes Ceto. She had the face of a beautiful woman but the body of a serpent. When she and her mate, Typhon, attacked the Olympians, Zeus beat them back but allowed Typhon, Echidna and their children to live as a challenge to future heroes.

The offspring of Typhon and Echidna were:

1. Nemean Lion
2. Cerberus
3. Ladon
4. Chimera
5. Sphinx
6. Lernean Hydra
