Harpy

The Harpy is an enemy in Castlevania video games and the most common type of Bird Person. First appearing in Haunted Castle, the Harpy has made itself known for being a quick and tough enemy to beat, and harder in numbers. It replaced the Eagle in its console debut in Castlevania III: Dracula's Curse, where it would drop Gremlin/Ghoul Rabbits. In later games, it would carry and throw knives in its talons instead. In Castlevania: Legacy of Darkness, it could grasp onto the hero with its claws and drop it from great heights.

Castlevania: Aria of Sorrow
Harpies are usually seen flying about to slow down players in their tracks. Harpies sometimes carry a knife to throw at a player before swooping down on them and attacking. In Chi no Rondo, Harpies also swoop in and carry the player, inflicting damage as well. In other games, they just fly about aimlessly, just like the Giant Bat.

Castlevania: Curse of Darkness
Harpies attack in a few ways. They either swoop down and slash you with their feet, pick you up and carry you, or fire a blue energy ball at you. You can steal from them as soon as they let you go from a grab attack. They are usually paired with Iron Gladiators, or another large monster like a Cyclops or Red Ogre. For some reason, the Harpy is the only female monster that is encountered in CoD.

Castlevania: The Arcade
The Harpy is the boss of the Lookout Tower in Castlevania: The Arcade.
