Echidna is known as the Mother of All Monsters. With her husband, the giant Typhon, she gave birth to such creatures as the Hydra, She-Demon, Stymphalian Bird, and Obie. Though her children are born "good" if they are to taste blood they become wild and "evil." The goddess Hera often exploits this, turning Echidna's 3 eldest children into monsters which she sends to attack Hercules.
