#1-12,14-16 (No #13) [1941-1946] Jim Barr was the son of a police officer who was killed and as a result took it upon himself to fight crime. He was rejected from the police for physical reasons, but got a job in ballistics. Like many characters of the time, he used chemistry to develop powers for himself; in his case greater muscle mass and brain power using his 'crime cure'. He also invented a Gravity Regulator Helmet (which was bullet shaped and gave him his name), which allowed him to fly and deflect bullets. Bulletman and Bulletgirl were Fawcett Comics' second most popular characters after Captain Marvel and the Marvel Family.
