Portrayed as the supervisor of a New York computer software firm in her 1984 debut appearance, Firestorm first encounters her in the course of one of his battles with a villain, where he inadvertently magnetizes and effectively destroys several of the computers storing the software programs in development. This results in millions of dollars in property damage, which threatens to ruin the software firm and leads to a heated confrontation between Felicity and Firestorm where she threatened to organize a class action lawsuit against him. Felicity would make recurring appearance, often taking an adversarial role against Firestorm and making a point of explaining what the collateral damage of his battles cost her and other civilians. On one occasion, a frustrated Firestorm lashes out against Felicity's confrontational behavior by using his molecular transmutation powers to transform her clothes to soap suds, a tactic he previously used on the supervillain Plastique. Humiliated from being rendered nude in public, Felicity retaliates by filing a lawsuit against him.
