Catwoman and Poison Ivy (one where they aren't at each other's throats)
or
Talia and Lady Shiva
In my dream, the world had suffered a terrible disaster. A black haze shut out the sun, and the darkness was alive with the moans and screams of wounded people. Suddenly, a small light glowed. A candle flickered into life, symbol of hope for millions. A single tiny candle, shining in the ugly dark. I laughed, and blew it out. - Joker
