Batwoman

A raven-haired costumed crime-fighter who functions periodically, from July 1956 onward, as the crime-fighting colleague of Batman and Robin. Batwoman is in reality Kathy Kane, a wealthy heiress and one time "Circus daredevil performer" noted for her outstanding ability both as a trapeze artist and motorcycle stunt rider (TGSB).

In September-October 1957, Batwoman whose true identity has by this time been deduced by Batman despite her attempts to keep it secret, apprehends fugitive criminal Elton Craig at an abandoned chemical factory, but before she has become temporarily endowed with super-powers, as the result of swallowing a special "radioactive capsule" invented long ago by the Kryptonian scientist Jor-El, father of Superman. After returning the captured Craig to Metropolis Prison, Batwoman, whose super-powers will not fade away for about 24 hours, meets with Batman, Robin, and Superman and relates what has happened to Her.
