Power Girl was one of Oracle’s first agents. Their short-lived partnership ended after a disastrous mission which resulted in a large loss of life. Power Girl believes that Oracle's poor leadership was responsible for the tragedy, being disgusted that Oracle would sacrifice hundreds of lives & herself following orders. Although she has worked with her again on a few occasions when needed, the relationship between the two is tense. In "Birds of Prey" #35, Power Girl admitted that she is primarily to blame for the tension, but is unable to overcome the memories of the deaths.
