Kusabi
In Fatal Frame 2: Crimson Butterfly, the Kusabi is extremely powerful ghost in the form of a shrieking, wizened old man. Whenever he appears, the only thing you can do is run for your life. If he catches you, it’s an instant death, and the music that plays when he’s nearby is enough to stop your heart in your chest. It’s bad enough that your only weapon is a camera, and now even that won’t help.
