Ekidonna

The Ekidonna (エキドナ, Ekidona) is an enemy which appears in Suikoden.

Information
During the late Gate Rune War, following the Last Battle, many monsters appeared in Gregminster Palace. Of these, the Ekidonna is said to be one of the most formidable of all enemies. Even a battle-tested warrior would struggle against the height of its vitality and magic power. But those who were able to defeat the Ekidonna had a chance to obtain the Windspun Armor, the best armour at the time. Warriors fortunate to get this armour unscathed would have obtained impregnable defensive power.

Trivia

 * The name Ekidonna is the romaji for the Echidna, who in Greek mythology was a half woman half snake creature, known as the "Mother of All Monsters" because most of the monsters in Greek myth were mothered by her, including Cerberus, the Chimera and the Gorgon. She is also the name sake of the slightly less horrifying real life animal, the Echinda.
 * With the highest non-boss PWR and MGC stats in the game, as well as having the highest Level and Potch pay out, the Ekidonna really lives up to its etymology as the "Mother of All Monsters".
