Diavolo is the main antagonist of JoJo's Bizarre Adventure - Part V: Vento Aureo. He is the father of Trish Una and boss of the Passione gang. Passione corrupts Naples by dealing drugs in the streets, making him Giorno Giovanna and Bruno Bucciarati's superior and greatest enemy. Diavolo first appears as his alternate personality, Vinegar Doppio. Doppio is Diavolo's young, innocent, and bizarre second personality. Doppio communicates with Diavolo with any number of objects (such as a frog or a young girl's ice cream cone) that can act as the "phone." His Stand is called King Crimson.
