Jim Pistol was a health and physical fitness expert who ran a live-in sanitarian for overweight men. He was a strong-willed man with light, wavy hair. The fugitive Pear-Shape sought refuge with Pistol, who was unaware of Pear-Shape's criminal activities. Pistol enrolled Pear-Shape in his fitness course and forced him to exercise rigorously. Years later, Pear-Shape and Pistol became partners in a weight-loss/fitness business.
