Sticky Fingers is a humanoid Stand of a height and build similar to Bucciarati's.
Its face is hidden apart from the mouth by a helmet-like covering adorned with a mohawk-like row of short spikes. Its body is covered in a dark body suit, with the chest and stomach exposed, and has pieces of padded armor over the shoulders, arms and wrists, knees and feet.
Zippers varying in size hang from the base of its neck and abdomen, the back of its hands, and the top of its feet.
Most media featuring Sticky Fingers portray it as being white and blue.
Personality
Sticky Fingers is one of the few Stands used in conjunction with its user's battle/Stand cry. Bruno's trademark line begins by stringing "ARI, ARI, ARI" along with his rapid punches; with "Arrivederci!" ("Goodbye" in Italian) at his finishing blow.
Ability
Sticky Fingers is a close-range Stand whose excellent strength and speed make it suitable for direct combat. In addition, it possesses a very versatile ability in the form of its zippers.
Zippers
Sticky Fingers' primary ability is to create zippers on any surface it touches with its fist, which it can remotely open or close at its leisure. For example, Sticky Fingers can hit a wall, unzip it to create an opening and go through it, then close the zipper.[2]
Bruno can even create zippers that cut through the entirety of objects, allowing him to dismantle them. With this ability, he can separate enemies into multiple pieces[3] and even perform a cutting attack by detaching something and then cancelling the zipper. How harmful the detachment is portrayed incoherently. When Mario Zucchero's head was removed, he was kept alive[4] but on the other hand, when Bruno himself sectioned parts of his own body into pieces, blood and oxygen could not circulate through the rest of his body as a result, slowly killing him as if his parts were actually cut off from each other.[5]
Inversely, Bruno is free to attach several things together with his zippers. It allowed him to block King Crimson's arm when it impaled his chest[6] or even attach another's arm to his body.[7] It also enabled Abbacchio to heal his severed hand.
Because the zippers are remotely opened and closed, Bruno can take advantage of the zipping itself. He can create long zippers over surfaces and control the zipping to rapidly reposition himself if he holds the zipper's handle, for instance to move down a lift shaft using the zipper to slow down his descent.[8] Moreover, nearly cutting an object in two then rapidly closing the zipper from a distance creates a makeshift jawed trap.[9]
If Bruno opens a zipper to inside a voluminous object, it actually doesn't show the interior of the object but a dark space in which Bruno can put objects like precious goods to safely store[10] or himself to hide.[2]
