Fly, Gray

グレー・フライ

Gray Fly appears as an elderly man with a horseshoe-shaped hairstyle and a stag beetle imprint on his tongue. He seems normal at first but is purely evil, adopting a modus operandi of killing his victims by severing their tongues with his Stand. His sadistic nature drives him to murder people simply for amusement. He is known as a Stand user who orchestrates multiple accidents and kills individuals to steal their valuables. Kakyoin notes that Dio did not need to use a spore to control him, suggesting he was likely just hired to eliminate the Joestar group.
