Echidna was the mother of all monsters, and she was angry. Hercules had fought and killed several of her offspring in the course of his adventures. Now Echidna wanted revenge. She planned to force Hercules' mother, Alcmene, to witness the slaying of her own son before she, too, was put to death. The instrument of Echidna's plan was Demetrius, suitor to Alcmene, but Hercules pursued them to Echidna's underground lair. Weakened by an arrow wound, Hercules still managed to defeat the monster mother, sealing her in a tomb forever.
