|“||You could be one inch away, pointing at me with ten guns... The ten bullets wouldn't even touch my Stand!||”|
—Gray Fly said about Tower of Gray's speed
Its modus operandi is to use its Gray Stinger and speed to tear out the tongue of an opponent, but it demonstrates no personality of its own apart from its user's.
It represents the Tarot Card The Tower, which symbolizes the interruption of a journey by something unexpected and chaos.
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 300 casualties.
- Tower Needle (タワーニードル Tawā Nīdoru?): Its defining feature is its long, extendable stinger, which protrudes from its mouth. It has enough force to tear flesh apart or force its way right through. Combined with its faster-than-light 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 great ease.
- 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 the same time in point-blank range and it would escape unscathed. This is later proven when Tower of Gray dodges Hierophant Green's Emerald Splash multiple times unharmed.
- 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.
- Tower of Gray's tongue resembles the mouth-like tongue of a Xenomorph from the Alien franchise.
