Gray Fly

Gray Fly is a minor antagonist in Part III: Stardust Crusaders.

Appearance/Personality
Gray Fly appears as an old man with a horseshoe hair style, and an imprint of a stag beetle on his tongue. He seems normal at first but is plain evil, taking up a modus operandi of killing his victims by cutting off their tongues with his Stand. His sadistic personality drives him to kill people just for fun.

History
Gray Fly was involved in many plane crushes and train accidents, including a plane catastrophe in England with 300 casualties. According to Abdul, he might have acted on Dio's orders.

Stardust Crusaders
Gray Fly first appears on a plane en route to Bangkok as one of the passengers. Since he is an old man, he does not fight Jotaro and the others directly, instead letting his Stand do the job. He manages to damage Jotaro thanks to his Stand's speed. In order to make his opponents understand his true powers and his intentions, he cuts off the tongues of the other passengers with Tower of Gray, then proceeds to write the word "Massacre" on the wall with their blood.

It is at this point that Gray Fly stands up, leaves his seat and tries to reach the bathroom, pretending to be nothing but a harmless old man. He then stops and starts screaming at the sight of blood, probably in a attempt to wake up the passengers and put the Joestar group into more trouble. However he is swiftly knocked out by Kakyoin, who stands as Tower of Gray's new opponent. Kakyoin manages to trick the Stand by distracting him with his Emerald Splash and while hiding the tentacles of his Hierophant Green among the plane's seats. The strategy succeeds, the tentacles grab Tower of Gray and destroy it, leading to Gray Fly's death as well.

However, before dying, Gray Fly managed to kill the plane's pilots in a last attempt to lead the protagonists to the same fate. Although his head and tongue were split in two because of Kakyoin's attack, he managed to stand up and taunt them, saying that they will never get to Dio even if they were lucky enough to survive the crash. He also warns them that Dio's own allies will be coming after the protagonists, beginning with Jean Pierre Polnareff.

Stand
His Stand is Tower of Gray. He and Abdul precise that the Tower is a symbol of something unexpected that interrupts a journey. Effectively, Gray Fly manages to complete his task pretty well, forcing the heroes to a much longer and more difficult journey towards Egypt.
