Fiery-Haired Flaming Feminine Firestorms

Lorraine was initially kidnapped by industrialist Henry Hewitt, with the purpose of blackmailing her father Senator Reilly into voting for a bill allowing Hewitt's company to have vast control over nuclear energy research. However, Hewitt also used the young woman as a test subject for his own experimentation, as he attempted to replicate the nuclear incident which initially birthed school student Ronald Raymond and physicist Martin Stein's alter ego of Firestorm. As Firehawk, Reilly was initially a pawn of Hewitt and later allied with Firestorm against him.

Danette Reilly was vulcanologist and New York steel mogul's daughter and sister of Rod "Firebrand" Reilly, who adopted the Firebrand alias once energy-based powers were granted to her as well. This occured when she was held hostage by Per Degaton and his supervillian henchmen, and during an incident his lieutenant Wotan struck Danette with a bolt of energy as she fell into a pool of lava within Degaton's artificial volcano. She also gained the power to emit heat and later, flight.

While Ronnie Raymond and Lorraine worked alongside one another, a romance ignited between the two. This occurred when Ronnie as Firestorm and and Lorraine as Firehawk worked side-by-side as costumed crusaders. While there was a brief meeting between Christopher Pike and Danette, as their fiery alter egos Vulcan and Firebrand, they were on opposite ends of the law. Although not having a relationship with Pike as Lorraine had with Raymond, Danette fell in love with another nuclear man named Terry "Cyclotron" Curtis. This relationship disintegrated while Terry delved into his research, and tragically ended soon after they were reacquainted when he adopted the alter of Cyclotron.
