The Echidna (エキドナ, Ekidona?), also known as the Naga, is a recurring creature in the Final Fantasy series, first appearing in Final Fantasy III. It is typically a serpentine humanoid that attacks the party while hanging upside down from the ceiling, and has access to several instant death abilities such as Quake and Death.
Appearances[]
Final Fantasy[]
The Echidna from Final Fantasy III appears as a boss exclusive to the Dawn of Souls and 20th Anniversary releases, encountered in Earthgift Shrine. The Echidna can be a dangerous foe due to mass usage of Instant Death abilities, such as Earthquake and Death, in addition to Flare, especially if fought as soon as the dungeon is unlocked.
Final Fantasy III[]
The Echidna appears as a boss encountered in the World of Darkness at the southwest portal. The Echidna primarily uses instant death abilities such as Death and Quake, in addition to Tornado to reduce targets to single digits and Drain to restore its own HP. In the NES version, it can also use Breakga, Flare, and Meteor.
Final Fantasy IV[]
The Echidna appears as an enemy exclusive to the Advance and Complete Collection releases. It is encountered in the Lunar Ruins, but is hardly a threat to the player at that stage in the game she is encountered. It fights using Vampire and Thundaga, and has a very rare chance of dropping the Assassin's Vest.
Final Fantasy IV: The After Years[]
The Echidna from Final Fantasy III appears as a boss encountered in the Depths during the final chapter of the game. It fights much as in III, utilizing Quake, Death, Flare, and Tornado, but can damage also a target's MP via Magic Buster.
Final Fantasy XIV[]
The Echidna appears as a boss encountered in 
The Void Ark, acting as the final guardian of the Shadow Queen Scathach's coffin. It appears as a lamia fought alongside Dexter and Sinister, and can fuse with the two cobras into its traditional upside down form. It is the only boss from the Final Fantasy III World of Darkness to not appear in some form in Final Fantasy XIV's version.

Etymology[]
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.
