Gargoyle

A Gargoyles are man-bat demons which spend much of their time as stone figures, but come to life when approached. The first Gargoyles did show their stone form and were in the games Super Castlevania IV and Castlevania Chronicles. The first gargoyles to be shown in statue form were in Castlevania: Rondo of Blood.

Other enemies in earlier games were called Gargoyles in the North American manuals, but were not designed to be Gargoyles in the original Japanese versions of the games. These include the Devils from Castlevania II: Simon's Quest and the Flying Skeletons from Castlevania III: Dracula's Curse (called Gargoyle Skeletons).

Trivia
There is an art of the Gargoyle in the manual of Dracula X. However, the Gargoyle doesn't appear to the game.
