She was the first costumed super heroine to ever appear in Major City. A single lightning strike turned her into an almost unstoppable powerhouse. She gained unmatched physical strength and speed. Unbeknownst to her, the energies that gave her her powers were that of a stray lightning bolt from the hands of Zeus himself.
The idea of costumes and logos weren't prevalent yet, in the 1920's when she got her powers, so her costume was more of functional choice than a statement. Her then trendy flapper style dress was not without it's meaning though, she had idolized the free spirited women of her time who had made the style popular and to her it helped amplify her tremendous physical strength to use her sexuality as well.
From bookworm to bombshell, LadyLightning, forged a new path for future super powered females.
