Larcen is a modern-day villainess, who at puberty developed a power that makes her immune to fatigue. She has nearly inexhaustible energy, and is thus very strong, agile, and physically tough. Later, as she turned her natural talents to crime, she acquired an experimental device that could create objects out of force. She paid an exorbitant sum and had the device installed into her body, so with a mere thought, her own natural energy can power the device, creating nearly any object she can imagine, but she is unable to create forcefields beyond the range of touch. She favors whips and swords, but is adept at creating thousands of tools for any of the various tasks she must perform as a cat burgular.
