Julia Remarque of Earth-One was a reporter who was the daughter of Alfred Pennyworth, who himself was butler to Bruce Wayne. While she was under the belief that with her mother Mademoiselle Marie's dying words Alfred was the man who had slain her, Julia sought revenge until Bruce as Batman was able to uncover the truth. She would soon after learn that Alfred was her estranged biological father, neither aware of the other's existence. Later, Julia was captured by the cold crook known as Mister Freeze, and then was saved once more by Batman.
Lorna Dawn of Earth-Two was a secret service agent charged with guarding European scientist Dr. Joar during an ocean voyage to the United States. They were interrupted by the intrusion of criminal Lanky Leeds who sought to exploit his success, however Joar's experimental cold gun went off. Blinded, Lorna was disoriented and later learned that a cold-themed villain known as the Icicle had plagued Gotham City. Enlisting the aid of Gotham City's Green Lantern, the pair tracked down Icicle and learned that he was actually Mahkent, assuming the civilian identity of Leeds to cover his tracks. When Icicle later returned, Dawn once more aided Lantern in defeating the criminal.
