Mario Zucchero

'Mario Zucchero is a minor villain in JoJo's Bizarre Adventure: Golden Wind. He is a greedy and reckless gangster who, along with his more level-headed partner Sale, serves as a rival member of Passione against Bucciarati's team and aims to retrieve Polpo's fortune before them.

Story
Zucchero learns about Polpo's fortune from Sale and that it was Bucciarati who was tasked to retrieve. Deciding to hide in Bucciarati's boat, Zucchero starts attacking his team members one by one by using his Stand, Soft Machine, to deflate them. He manages to capture Narancia, Mista, Fugo and Giorno with said method before Abbacchio manages to find out about his Stand's power with Moody Blues. Abbacchio is eventually attacked by Zucchero before finding out about his location but not leaving his trail of blood as a clue for Bucciarati. Bucciarati then realizes with Sticky Fingers that Zucchero hidden another boat in top of Bucciarati's and was hiding in the tiny space between them. He then manages to sink the other ship, revealing Zucchero's location in the process.

Zucchero tries to kill Abbacchio if Bucciarati were to come any closer but Bucciarati manages to behead him with his Stand, realizing that he is too slow in actual combat. Zucchero is then tortured by Bucciarati's gang for more information: while Narancia, Abbacchio and Fugo keep kicking his torso, Mista hangs his head by using a fish hook to keep his eyelid open and then puts sunglasses on his head which ends up roasting and blinding Zucchero's right eye. Bucciarati then points out that Zucchero is a hardcore gangster and won't leak out any information that easily. Abbacchio's Moody Blues recreates the events caused by Zucchero which shows that he had called his partner Sale hours before and made an appointment with him on Capri. Zucchero is then tied up and left alone on the boat, together with Sale when Mista manages to defeat him later on.

Powers
Zucchero's Stand, Soft Machine, is a stand best suited for sneak-attacks. It has the ability to deflate humans and objects as if they were air balloons by stabbing them with a tiny dagger. It is not suited for close-range combat, however, as Bucciarati found out and is too unskilled and slow to pose any danger head-on.

Trivia

 * Interestingly enough, Zucchero is one of the few villains in Golden Wind to have both first and last name (the other being Risotto Nero), despite being such a minor threat to Bucciarati's group.
