The Echidna is an enemy encountered in the Lunar Ruins in the Advance version of Final Fantasy IV, resembling the famous Final Fantasy III boss. At the point in the game she is fought, she is not a very big threat to the party. Simple Flare spells and physical attacks are more than enough to do her in, though one Holy spell or attack from Ragnarok will be more than enough to kill her in one blow.
[view·edit·purge]In the most ancient layers of Greek mythology, Echidna was called the "Mother of All Monsters". Echidna was described by Hesiod as a female monster spawned in a cave, who mothered with her mate Typhon. Her face and torso is that of a beautiful woman, sometimes depicted as winged, but always with the body of a serpent. She is also sometimes described as having two serpent's tails. She was said to be the mother of such famous Greek monsters like Cerberus and the Chimera.
