As children, Al Capone and Manny extorted protection money from other students at grade school. Manny continued to serve Capone in adulthood and when they moved to Chicago. In death, Manny remained his second in command and served him in the Netherworld. Decades later, once the Ghostbusters arrived, Manny was dispatched to gather them up and take them to Capone. However, they escaped. Ray Stantz and Winston Zeddemore later met Manny's girlfriend and fled from Manny. Peter Venkman and Egon Spengler destroyed his 1934 Ford and trapped him with modified Particle Throwers.
