Melone is a young, skinny man with an average height. He has long straight hair descending down to his shoulders, as well as long bangs on one side of his face.
Inspired by Venetian design, Melone's most distinctive feature is his clothes. He wears a dark suit with a concentric circle motif, lacking the right sleeve and a large part of the right side. Melone also wears matching gloves and shoes, as well as a transparent mask covering his right eye. Over his trousers, Melone sports two decorative chains around his shins on each leg.
Melone shows himself to be a polite man in most circumstances. Approaching every activity with cold professionalism, he physically inspects his future victims, looking them more like cattle to breed his Stand than fellow human beings. The TV anime also emphasizes his lustful side, showing him openly licking his lips in delight as he observes a beautiful woman's legs and feet, something his teammates are humorously disturbed by.
Melone always reacts jovially when circumstances match or exceed his expectations, exclaiming himself "Di Molto!" On the other side, when things do not go his way, he becomes nervous, still remaining cool-headed enough to issue tactical instructions, likely due to the fact that he is not the one facing immediate danger.
Melone is one of the least confrontational enemy Stand Users in the series, favoring hit-and-run tactics or laying traps, never reacting with violence to every setback, and even advising his Stand to flee instead of continuing to fight.
- Main article: Baby Face
Melone wields the Stand Baby Face, which is a computer-like humanoid Stand he uses to create autonomous long-range Stands also named Baby Face which he can direct to kill his targets. He needs to find a blood sample of his target and a woman to breed said Stand before he can act.
Pseudoscience knowledge: Melone is well-versed in pseudosciences used to divine things such as character compatibility or a future child's characteristics. This serves him to determine the quality of the Stand he will breed in function to his target.
Melone was a member of La Squadra Esecuzioni, a team of nine assassins working within Passione. However, the team was frustrated they only received compensation for each kills while the rest of the gang was getting rich from the drug trade. One day their teammates Sorbet and Gelato disappeared while they were trying to investigate the Boss' past. They found Gelato choked on a gag in his house, with a piece of paper on which was written the word "punishment". Later, the team received the sectioned body parts of Sorbet encased in formaldehyde, showing the team the power of the Boss. They despaired of ever finding about the Boss. However, they then heard about Trish Una, and thought that she would be the key to discovering the Boss' Stand ability. The team rebelled and began searching for her. Just after Trish was taken in by Pericolo, La Squadra Esecuzioni ransacked Donatella and Trish's appartment in search for clues, missing a crucial picture of Donatella that was taken by the Boss himself.
The anime adaptation expands on his activities. The night Sorbet and Gelato disappeared, he was on an assignment with Formaggio, Pesci and Prosciutto. He didn't do anything but lusted after the target's date after seeing her legs, which weirded his teammates out.
Melone is first shown collecting a blood sample left from Bruno Bucciarati's battle with Prosciutto and Pesci for the Homonculus Materialization of his Stand, Baby Face. He later finds a woman while on a train and proceeds to examine her. Her bad temper, selfishness and overall incompatibility with Bucciarati makes her the ideal mother for Baby Face's child and thus he summons Baby Face to do its deed. He then leaves for another empty wagon, supervising Baby Face's growth. Once the homonculus is born, he then educates it to kill off Bucciarati's group and capture Trish Una. It surpasses his expectation and leaves for its target before it is ready, but Melone decides to trust in it.
When Baby Face locates Team Bucciarati and launches its attack within Coco Jumbo, Melone is seen giving it orders from his computer. However, Melone's plan inadvertently causes Giorno Giovanna to not only deal damage to Baby Face, but its ability allowed him to discover Gold Experience's indispensable ability to repair injuries through its basic life-giving power. Melone eventually loses control of Baby Face, who proceeds to act independently and ends up nearly burning to death.
After the defeat of his Stand, he's called by Ghiaccio about the wreckage. Ironically, before he could generate another homunculus incidence of Baby Face, a cube portion of his burning Stand finds its way back to him as a venomous snake animated by Giorno and bites his tongue, killing him off-panel.

JoJo's Pitter-Patter Pop! (Android/iOS)
In the light novel JORGE JOESTAR, an iteration of Melone lives in the 37th universe, appearing similarly to his original universe counterpart. He is not actually mentioned in the novel by name but he is drawn in an illustration.
Nero Nero Island, where the base of Passione is located, suddenly grows legs and starts moving through the ocean headed toward Morioh. Some ordinary citizens panic and attempt to escape at the island's harbor. Melone, Cioccolata, Secco, Prosciutto, Pesci, and Ghiaccio ambush and murder them. Secco's Evil Dead conceals the harbor, making their actions invisible to those within the island, such as Bruno Bucciarati. One man manages to escape and tries waving desperately toward Morioh for help before he is killed as well.
The Mafia members move the bodies out of sight by dropping the bodies in the water between the boats, or by tossing them into the tall grass by the side of the road to the harbor. Nero Nero Island suddenly crashes into the barrier surrounding Morioh and flips upward. Its propulsion causes it to tear through the barrier and lands into Morioh Harbor. Cioccolata and the others start firing bullets and rocket launchers at random civilians and houses in Morioh, attempting to shoot Jorge Joestar as well when he runs by underneath them. The mafia members then jump off the island and head to Budogaoka gymnasium with several weapons.
- His catchphrase "Di Molto" (ディ・モールト (非常に) Di Mōruto) translates to "Of Very" in English and is not actually used in Italian, being grammatically awkward. "Molto bene" (Very Good) would be a correct form of his superlative.
