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 Once, grief-stricken at the deaths of her children and bent on revenge, Echidna hired Demetrius lure Hercules into a trap. Demetrius faked a loving relationshipwith Alcmene and then kidnapped her and brought her to Echidna. Hercules followed and was able to defeat Demetrius and rescue Alcmene. At his mother's request, Hercules spared Echidna's life. The hero sealed her in a cave. With help from Hera, Maceus and his men re-opened the entrance to Echidna's cave hoping to get Echidna's help to kill Hercules. Echidna agreed but changed her mind when Hercules reunited her with her husband Typhon who had been imprisoned for over a century by Hera. In a battle with Hercules, Echidna accidentally killed Maceus When it came to Jason and Alcmene's wedding, Hercules was told by Iolaus that Echidna can't come because she is pregnant. Echidna later gave birth to Obie. Hera sent her Head Archer to retrieve the baby so it could be trained as a killer. Echidna refused. Klepto pretended to be a friend of Hercules' and kidnapped Obie to bring him to the warlord Bluth so he could be trained for Hera, Klepto eventually became fond of Obie and helped to get him back to his parents. Echidna then accepted Klepto's apology and he became Obie's babysitter.
