Oscar Zavarelle is one of the Don Stracci's caporegimes. A sadist and a pervert, Zavarelle has perpetrated atrocious rape crimes against innocent young women and girls. In a revenge scheme against Corleone behind-the-scenes man, The Trojan, Zavarelle beats and rapes his eighteen year old sister to prove he could get to him. The Trojan brings Aldo Trapani in and sanctions a hit against Zavarelle, who is hiding out in the sewers of Hell's Kitche.

Oscar Zavarelle was murdered by Corleone associate Aldo Trapani.
