Circus stunt-cyclist and trapeze artist Kathy Kane long admired the Batman. Receiving a considerable inheritance she decided to become a costumed crimefighter patterned after her idol. She constructed a mansion atop of an abandoned mine tunnel, filling it with a state-of-the-art crime-lab, constructed a Batcycle, designed a costume and embarked on a career as Batwoman.

In time she would update and modify her transportation to a more formidable vehicle which would be adopted by other members of Batman's allegiance of crimefighters.
