Energy first discovered her abilities shortly after she spotted her father absently creating an electrical arc between his fingers when he was repairing their car and wanted to test a component. Her father's abilities were relatively weak, but as she grew into her late teens, Energy's own powers expanded; she learned how to create powerful lightning bolts and direct them with great accuracy. Not knowing where to begin "superheroing", she travelled to Manhattan to seek out Max Dalton; under his guidance she began her career as Energy, and soon branched out on her own.

Costume:
Energy has had several costumes; her first was primarily white with lime-green bands at her wrists, neck, abdomen and calves. Realising quickly that a white costume only helped to make her a target, she soon adapted it to charcoal grey.
