Bulletgirl was originally a character from Fawcett comics. When DC acquired the Fawcett characters, Bulletman and Bulletgirl were among them. She was incorporated to the pre-crisis universe of earth-S and later became one of the golden age heroes from the main universe, but always keeping an strong connection to Bulletman and Captain Marvel world, also originally Fawcett properties.
Susan Kent was the daughter of police officer Sgt. Kent, who often worked with forensic scientist Jim Barr. She started out as Jim’s lab assistant and later his girlfriend. It wasn’t long before Susan discovered Jim’s alter ego as Bulletman and wanted to share in his adventures. Jim manufactured another gravity regulator helmet for her, which enabled her to become his partner Bulletgirl. As Bulletman and Bulletgirl, the two made a formidable fighting team and were often known as the “Flying Detectives”. The two would go on to fight such villains as the Black Rat, the Black Spider, Dr. Riddle, the Murder Prophet, the Weeper, and the common gang of Nazi saboteurs. The duo would eventually add Bulletboy and Bulletdog (their pet) to the Bullet Family.
As Bulletgirl, Susan was a founding member of the Crime Crusader Club along with Bulletman, Minute Man and Captain Marvel Jr.
Before Crisis on Infinite Earths, Bulletman and Bulletgirl lived on Earth-S in the DC Universe along with the other Fawcett heroes. During this time, Bulletgirl was part of the Squadron of Justice (along with Bulletman, Spy Smasher, Ibis, Mr. Scarlet and Pinky), which would meet the Justice League of America (Earth-1) and the Justice Society of America (Earth-2) in what was called a "Crisis on Multiple Earths". The three teams fought King Kull and villains from all three Earths.
In Post-COIE, Susan Kent continued to be one of the Mystery Men of World War II along with her boyfriend Jim Barr. Susan was among a small group of heroes of the 1940s called upon by the wizard Shazam to aid in his fight against his daughter Blaze and the Seven Deadly Enemies of Man. Blaze was defeated and Shazam contained the Seven within ridiculous containment shells. It is yet to be mentioned if Bulletgirl was a part of the All Star Squadron during WWII or part of another team (Crime Crusader Club) combining all former Fawcett heroes
Susan married Jim Barr and later gave birth to their daughter, Deanna. Susan’s final fate is still unclear. She either died (of old age most likely) or is retired now.
She met Alix Harrower (Bulleteer) at a superhero convention in Bulleteer #3. She criticizes Alix for her revealing costume.
Skills and Abilities
Susan Kent injected herself with the same serum developed by Jim Barr (Bulletman), granting her super strength and a certain degree of invulnerability, allowing her to perform the same power stunts Bulletman does (Master Comics #13 1941).
Gravity Regulator Helmet
Flight – The helmet allows the wearer to defy gravity and directional maneuverability even at sonic speeds.
Deflection – An invisible electromagnetic field emitted from the helmet repels approaching objects (such as bullets) from striking the wearer.
