Prosciutto is a man of slim build, having short blond hair and keeping them braided into three short mats at the back of the head.
Prosciutto wears a dark two piece suit with a spiderweb like motif, under which he wears a bright shirt. Prosciutto keeps one collar and one stylised pendant around his neck.
Prosciutto is a fairly serious man. He is shown to always be focused on his mission and adhering to La Squadra's motto of holding one's ground even mortally wounded to the letter, which he puts it into practice and expects his underlings(s) to also do the same. He doesn't tolerate any deviance of that attitude, especially when it's from his comrades and subordinates, and failing to adhere to the ideal such as in the case of Pesci on one occasion, a brief beating would be handed out as a reminder. Prosciutto is usually very composed, meeting any obstacle with cold efficiency, and carrying out his objectives without hesitation.
Despite his serious and cold demeanor, he is also shown to have a somewhat caring side towards his comrades. As the superior of the assassin duo, Prosciutto frequently points out his fellow assassin Pesci's lack of confidence in his own abilities, and on multiple occasions tries to comfort and convince him of his own capabilities. This reliance is not unfounded, however, as Bruno Buccellati determines from his battle with Pesci that Pesci's abilities are actually more dangerous than Prosciutto's.
He also possesses a strong will, as shown when he suffers near-fatal wounds from being caught in the train's wheels and uses the last of his determination to keep his Stand's ability in effect for as long as possible.

Prosciutto uses his Stand The Grateful Dead to age people in a large area, discriminating between individuals via their body temperature.
Prosciutto and Pesci, are sent after Buccellati and his gang to capture Trish Una in order to find out the boss' identity. Although they manage to catch up to the gang at the train heading to Florence, they soon loose sight of them due to a newly found turtle's Stand.
In order to flush the gang out, Prosciutto decides to use his Stand, The Grateful Dead, to age everyone onboard the train. This forces Guido Mista to come out from hiding to try and stop the aging. After Mista has a confrontation with Pesci, Prosciutto is able to take down Mista from behind and use his own gun to shoot him in the head, supposedly killing him. Soon after, Prosciutto and Pesci are able to find the turtle holding the gang, forcing Buccellati to come out and fight. After a short scuffle, Buccellati manages to use his Sticky Fingers to make Prosciutto fall out of the train. Out of sheer luck, Prosciutto manages to get himself caught in the train's wheels and barely survive with fatal wounds. Knowing he would die, he determined that he would use his Stand and hold out long enough to give Pesci the chance to kill the gang, and steal Trish away. When Pesci died at the hands of Buccellati, Prosciutto lost his will to live and soon died along with him.
- He is called "aniki" ("big bro" in Japanese) by his partner-in-crime Pesci.
- Interestingly enough, Gyro Zeppeli's horse, Valkyrie, shares Prosciutto's hairstyle.
- Surprisingly, despite being named after the Italian word for "ham", his favourite food is actually fishstick.
