Gray Fly

Gray Fly presents as an elderly man, his scalp ringed by gray hair in a horseshoe around a bald crown. A telling detail sets him apart: the imprint of a stag beetle stamped upon his tongue, which in the anime surfaces only after his Stand is destroyed.

His Stand, Tower of Gray, takes the shape of an enormous, nimble stag beetle said to outpace even Star Platinum, and it rends flesh with ease, most infamously by slicing away its victims' tongues. As a person he hides his cruelty behind an ordinary front, but he is simply and thoroughly evil, killing for amusement and staging accidents to rob the dead. Fittingly, the Tarot card he embodies, The Tower, signals a sudden upheaval that derails a journey near its end, which is exactly the role he plays for the Joestars.

Long before Egypt, Gray Fly built a reputation among Stand users for engineering mass-casualty disasters disguised as crashes and wrecks, including an English aviation catastrophe that claimed three hundred lives, all without leaving a trace of his hand in them. His notoriety reached the fortune-teller Avdol, though the insectile form of his Stand stayed a mystery even to him. Sent by Enya the Hag as one of DIO's Tarot assassins, he boards the group's Cairo-bound flight posing as a harmless old passenger.

Tower of Gray strikes at Jotaro first, then mutilates the other travelers and scrawls the word for slaughter in their blood to broadcast its intent. When Gray Fly rises and feigns terror to sow panic, Kakyoin knocks him down and outwits the beetle, hiding Hierophant Green's tentacles among the seats while distracting it, then tearing the Stand apart and killing its user. Even so, Gray Fly manages to slay the pilots before he dies and taunts the heroes that they will never reach DIO, and only Joseph's flying skill spares the passengers as the plane goes down, leaving the group barred from air travel for the rest of the trip.
