Stardust Crusaders - Chapter 10 
Jotaro manages to block the enemy's attack with his teeth. Avdol recognizes the Stand as Tower of Gray, who is responsible for numerous slaughters disguised as accidents, such as a plane crash that killed 300 victims the year before.
Tower of Gray moves away from the group and tears off four passengers' tongues by flying through their heads. It then writes the word "Massacre" on the wall of the plane with the tongues it's gathered.
Kakyoin, fearing that Magician's Red and Star Platinum would endanger the passengers, decides to fight him alone. He throws several Emerald Splashes at the Stand, but it dodges them all. While Tower of Gray is about to finish him, Hierophant Green uses the tentacles he had hidden under the seats to pierce through the bug-like Stand. A bug-shaped wound appears on the Stand user's tongue, then his head and tongue split in two. He was an old man, a passenger of the plane.
