Susan Kent was born the daughter of police officer Sgt. Kent on the parallel reality known as Earth-S. As an adult, she became romantically involved with inventor Jim Barr, and soon discovered that he was also the costumed hero known as Bulletman. Barr created a second Gravity Regulator Helmet and gave it to Susan whereupon she became his sidekick Bulletgirl. Susan and Jim were soon married and they shared in many adventures together throughout the 1940s. Susan occasionally teamed-up with other empowered heroes such as Captain Marvel and his sister Mary Marvel. Bulletgirl and Bulletman became members of Shazam's Squadron of Justice and fought up against menaces such as the savage King Kull.
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, Doctor Riddle, the Murder Prophet, the Weeper, and the common gang of Nazi saboteurs. The duo would eventually add Bulletboy and Bulletdog to the Bullet Family.

- This version of Bulletgirl, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
- Bulletman and Bulletgirl were Fawcett Comics' second most popular characters after Captain Marvel and the Marvel Family.
- Susan Kent was created by writer Bill Parker and artist John Smalle, and turned into Bulletgirl by artist Al Carreno, for Fawcett Publications. In 1953, National Periodical Publications settled a long-running lawsuit against Fawcett citing that the character of Captain Marvel bore too much of a resemblance to their own character, Superman. After settling the case (by agreeing to no longer publish Captain Marvel), Fawcett discontinued publication of their entire comic book line and Bulletgirl lapsed into obscurity. In 1972, DC Comics licensed many of the Fawcett characters, including Bulletgirl, and established that they existed on the fictional parallel world known as Earth-S. The Fawcett characters made several appearances throughout various Silver Age DC titles including Shazam, World's Finest Comics and Justice League of America. In 1991, DC bought the Fawcett characters (including Bulletgirl) outright. However, most of the Bulletman & Bulletgirl stories lapsed into public domain prior to the said acquisition, which would later allow AC Comics to reprint their Golden Age adventures.
- Although Susan Kent debuted in the first Bulletman story in Nickel Comics #1 (May 1940), she did not become Bulletgirl until Master Comics #13 (April 1941).
