One of the Stracci Family's caporegimes, the other being Leon Grossi.
A close friend of Salvatore Stracci, Oscar Zavarelle was known as a sleazy thug who had a weakness for young girls. Despite these vices, he was known as a competent executioner who could also charm his way past racket bosses and merchants. He was known to have a fierce hatred of the Corleone's hitman, Angelo Granelli, also known as The Trojan. Despite numerous attempts to bring down his rival, Zavarelle failed, and instead found revenge by viciously assaulting Granelli's sister. This act cost him his life, as Zavarelle was executed by Aldo Trapani after he was ratted out by one of his own, underpaid bodyguards.
