Bulletman is a Golden Age Super Hero. He first appeared in Nickel Comics #01 (May 1940) published by Fawcett Comics.
Bulletman was Jim Barr, the son of a police officer, who was killed in the line of duty, and as a result of this, decided to fight crime. He tried to join the Police Force, but was rejected for physical reasons, but he got a job working in ballistics.
He experimented with chemicals to develop powers for himself. He gained increased muscle mass and brain function. He also invented a 'Gravity Regulator Helmet', which was bullet shaped and gave him his name. It allowed him to fly and deflect bullets. His formula was shown to make him strong enough to smash a tank.
Bulletman created a second helmet for his girlfriend and later wife Susan Kent, daughter of policeman Sergeant Kent. She adopted the name Bulletgirl. The helmet is shown to be so strong that when Bulletgirl was run over by a Nazi tank, she was only knocked out.
Bulletman and Bulletgirl regularly battled villains such as, Joker, Weeper, Shade, and Doctor Light. They also appeared a few times with Captain Marvel and his family.
