The Asp, Black Mamba, and Diamondback were close friends as well as founding members of Sidewinder's super-villain team, the Serpent Society. When Diamondback began dating Steve Rogers, the team acted behind scenes to make sure that her first real date was uneventful. After learning of Diamondback and Cap's relationship, the Society's new leader, King Cobra, had Diamondback kidnapped and placed on trial, fearing that she would reveal the groups secrets to the Captain. Diamondback was found guilty by her fellow serpents and sentenced to execution. Black Mamba and Asp objected but were overruled by King Cobra. To save Diamondback, Black Mamba and Asp called in a favor from their former leader, Sidewinder, also Black Mamba's ex-boyfriend and they rescued Diamondback, however in retaliation, King Cobra captured Asp and Black Mamba. Diamondback then hired Paladin to help her free the pair. Together, with Captain America, and Paladin, the five combined to defeat the Serpent Society. Fearing retaliation, Diamondback suggested they form their own group, B.A.D. Girls, Inc., the "B", "A", and "D" being the initials of their combined codenames.
B.A.D. Girls, Inc. first appeared in Captain America #385 (May 1991); Mark Gruenwald was the writer.
When Serpent Society members captured Diamondback, MODAM intervened and kidnapped Anaconda and all three girls to enlist them for Superia's army of Femizons. While on Superia's cruise ship, Asp and Mamba befriended Zambian criminal javelin expert Impala, while Diamondback was attacked and almost killed by Snapdragon. Traumatized, Diamondback decided to quit adventuring and the team were rescued by Captain America and Paladin who once again joined forces to defeat Superia and her Femizons. After the battle, Captain America offered to clear their names but the girls declined.
Later, when Mamba pulled the image of Diamondback's greatest fear from her, which was Snapdragon, Diamondback quit the group in anger. Black Mamba and Asp decided to investigate, seeking Snapdragon. In New York, the pair were attacked by Battleaxe, Steel Wind, and Golddigger. who were seeking the reward Superia had placed on their heads. Impala came to their rescue and joined B.A.D. Girls Inc., replacing Diamondback. The new trio briefly fought Sersi when stealing a Serpent Saucer from the Society's old headquarters and eventually tracked Superia and Snapdragon to an A.I.M weapons exposition in Boca Caliente. However, when Snapdragon was killed by Diamondback, the threesome lost their immediate goal, and the group eventually dissolved.
Diamondback regained her confidence and she contacted her friends and their group remained intermittently active. Diamondback worked for S.H.I.E.L.D, while the Asp and Black Mamba both freelanced. Mamba briefly worked for Justin Hammer against the Thunderbolts. Later, Asp and Mamba rejoined the Serpent Society when they were hunting what King Cobra believed Diamondback, which turned out to be an LMD.
The founding B.A.D Girls later reunited when Cable anonymously hired them to steal a new computer hard drive from the Dominus Corporation. After battling Deadpool for the technology, they determined that it had already been stolen by Shen Kuei, and confronted him in Hong Kong. Aiding Deadpool against an army of Makeshift and Rive clones, they completed their contract, and the trio went their separate ways until their next hire.
