You could be one inch away, pointing at me with ten guns... The ten bullets wouldn't even touch my Stand!

—Gray Fly about Tower of Gray's speed

Tower of Gray (タワー・オブ・グレー(灰の塔) Tawā Obu Gurē) is the Stand of Gray Fly featured in Stardust Crusaders.


Tower of Gray appears as a large, dark stag beetle about the size of one's hand with intricate patterns on its shell. A hidden, toothed, secondary jaw can spring out from its mouth.[1] Despite having the general form of a beetle, it also possesses teeth in its mouth.[2]

Tower of Gray is generally portrayed as being a red-eyed bug with a jet black shell, and blue patterns.

The Tower

Tower of Gray's modus operandi is to use its second mouth and speed to tear out the tongue of an opponent, but it demonstrates no personality of its own apart from its user's.

Tower of Gray specializes in making attacks look like accidents. Avdol comments that it is responsible for many cases of arson, plane and train crashes, and most recently an accident in England that caused about 300 casualties.[2]

It represents the Tarot Card The Tower, which symbolizes the interruption of a journey by something unexpected and chaos.[2]


Destructive Power










Developmental Potential



Tower of Gray is a small and fragile Stand. However, it is also incredibly fast and nimble, and its secondary jaw grants it unsuspected destructive power.

  • Secondary Jaw: Its defining feature is its long, extendable stinger, which protrudes from its mouth. It has enough force to tear flesh apart or pierce its way right through. Combined with its great speed, Tower of Gray is capable of killing multiple people in a very short amount of time and even go through the head of a person with ease.[1]
  • High Speed: Perhaps one of its greatest traits is its amazing speed; Tower of Gray is able to easily outmaneuver very fast Stands, such as Star Platinum and even Hierophant Green's Emerald Splash at close range. Its speed is so incredible that, according to its user, Tower of Gray could have several guns shooting at it at the same time in point-blank range and it would still escape unscathed. Moreover, Tower of Gray's speed is completed high flying control, as it able to write words in cursive while flying and can navigate its way through Hierophant Green's Emerald Splash multiple times unharmed. However, the Stand cannot dodge something it doesn't see coming, and thus is vulnerable to sneak attacks.[2]

  • Araki was inspired to create Tower of Grey after imagining how annoying it'd be if an insect was trapped inside of an airplane mid-flight.[3]
  • Tower of Gray's tongue resembles the mouth-like tongue of a Xenomorph from the Alien franchise.
  • The plane crash in England Tower of Gray is said to have caused may be a reference to the Pan Am Flight 103 disaster, in which a plane flying over Britain was bombed and crashed into the ground, killing 270 people.
