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.

Batwoman attempts to use her newly acquired X-ray vision to peer through the Dynamic Duo's face masks, but Batman has already taken the precaution of asking Superman to line their masks with lead, which X-ray cannot penetrate. When Superman makes a remark to the effect that Batman has outwitted her, Batwoman becomes furious. "I have got Super-powers for 24 hours,"she declares, "and I will use them to discover your secret identities somehow! From now on, I am out to learn your secrets!"
