Fan Casting Karen Starr/Kara Zor-L in Birds of Prey

Power Girl was Oracle's first operative, before she took in Black Canary. This first partnership was doomed, since Power Girl was unable to save a shipload of people. She has worked occasionally with Oracle in subsequent episodes but the two have a very poor relationship; she was invited to return to the team in issue #100, but stated she would do so "when Hell freezes over", despite begrudgingly appearing before and since to assist Oracle. The animosity between them is the opposite of the traditional Batgirl/Supergirl friendship.
