Possessor

Possessors are small pureblood Heartless that appear in various titles in the Kingdom Hearts game series. They appear as small clouds of black vapour with four purple horns and the trademark yellow eyes and jagged mouth shared by most types of Heartless.

Possessors can attack by swatting at prey with smoky-looking arms or by firing small projectiles of dark energy. However, their true power lies in their ability to take control of inanimate objects; in Kingdom Hearts II, Possessors can possess the stone statues within Beast's Castle, turning them into Gargoyle Knights and Warriors.
