Harpy

The Harpy (ハーピー, Hāpī) is a boss enemy which appears in Suikoden II.

Information
The Harpy is a terrifying creature with the upper body of a woman but the wings and lower body of a bird. It was spotted on Mt. Rakutei during the Dunan Unification War and was a difficult beast to defeat, even for the New State Army. Striking with wind element magic and stunning its foes with ease, this creature held no glaring weakness, making it a difficult foe to bring down.

Trivia

 * If you leave the Highway Village sidequest until after you liberate Rockaxe, then the Harpy will have boosted stats.
