Verrocchio is a minor mob boss, representing the Italian mob on Roanapur. Once one of the major operators on the island, his power and reputation had been supplanted when Hotel Moscow and Balalaika had moved in, taking all his drug trafficking routes. He had tried to use the Vampire Twins, Hansel and Gretel, to kill her and Mr. Chang in order to consolidate his own power and win back his customers. He later got killed by the twins on one of their psychotic whims.
