Liberty Girl became active as a costumed crime fighter in the late 1950s. Liberty Girl was the paramour of the crime-fighter calling himself the Yankee Clipper. Her origin's and connections to Yankee Clipper out of costume were never revealed, just her first name was mentioned as Beverly.
In 1958, agent Jacob Scott of the Defense Department acquired assistance from Yankee Clipper, the Black Fox and Liberty Girl. However Liberty Girl and the others were completely unaware that Agent Scott was really a Skrull spy who was attempting to reclaim his ship which had been in the custody of the United States government since it crashed on Earth in 1947. The mission was further complicated when the appearance of another Skrull spy named Zuhn also in search the ship. Zuhn then used the ships alien energies to mutate one of the Earth scientists whom were attempting to study the ship into a monster. Liberty Girl and her costumed comrades were assisted in battling the monster by the Monster Hunters. Ultimately, the Skrull spy escaped, and the monster reverted to normal. The heroes also stopped Blackjack and Scythe two costumed criminals hired to assist the spy. Zuhn was also blasted by the ships energies disrupting his shape-shifting powers, and took to calling himself Effigy. Scott pretended that the energies "mutated" him to further cover his Skrull physiology. Yankee Clipper then gathered Liberty Girl and the others and formed a team called the First Line.
In the spring of 1961, Liberty Girl joined her teammates on a mission to San Francisco where they assisted the Hipster in thwarting one of the Yellow Claw's acts of terrorism which involved manipulating the amnesic Sub-Mariner.
Liberty Girl joined her comrades to investigate a premonition from their teammate Nightingale that there would be danger in Dallas, Texas on November 21, 1963. There they found the shape-changing Chimera and the Howler had broken into a Stark Industries building to steal a new guidance system. However Chimera was really the Skrull Zuhn in disguise. During the battle Liberty Girl got too cocky and was fatally slashed by Chimera, dying in battle. Effigy avenged her death by slaying Chimera. Effigy figured that the death of Liberty Girl would make major news, however her death was overshadowed by the assassination of President Kennedy a day later.
