Vittorio Cataldi (ビットリオ・カタルディ,Bittorio Katarudi) is a character from the light novel Purple Haze Feedback.
Vittorio is a member of Passione's former Narcotics team.
Vittorio is a puny teenage boy, with a frail build, said to have large eyes and sunken cheeks by Zucchero. His body is covered in scars from self-inflicted injuries used to activate his Stand. He possesses a very large bang hanging in front of his face.
Vittorio wears a sleeveless cagoule from which two chains hang, each decorated by one six-pointed star. He also wears a pair of tall sneakers going up his calves.
Vittorio is a psychotic masochist, obsessed with pain. He has a habit of cutting himself with his dagger, expressing pleasure with a loud "Gigigigigi!" while doing so. This masochism is tied to his belief that pain calls the life force inside him. In a related way, Vittorio thinks that civilized life is lacking and that it is a veneer for the emptiness of life, hence his love of pain.
Otherwise, Vittorio acts like a typical thug. He is uneducated and rude, sometimes overfamiliar with people and quick to seek fights. Likewise, he doesn't care about the crimes he's committed. According to Cannolo Murolo, Vittorio doesn't care about anything as he was born at the bottom of society, treated like scum and given no hope. As a result, Vittorio lashed out at everything around him. However, he genuinely admires Massimo and is loyal to him.
Vittorio's Dolly Dagger is a Stand appearing in the form of a knife. He can reflect 70% of all damage inflicted to him into anyone whose reflection is on the blade. It gives him a surprising durability and can be fatal if someone recklessly attacks him.
Vittorio crossed to Taormina, Sicily, with Massimo Volpe to recover the stone mask hidden in the cathedral of Syracuse, but it had been destroyed by Cannolo Murolo, preventing them from obtaining it.
Vittorio activated his Stand to attack Murolo, but because of the characteristic of Murolo's Stand, Vittorio was the only one getting significantly damaged by his own attacks. Murolo advised him to stop fighting and surrender to Giorno, but Vittorio continued using his Stand frenziedly and eventually died from bleeding out.
