Biography
Power Girl first appears at Batman's memorial, dressed in a revealing black dress. While Hulk drinks alone, she walks up to him and offers her condolences, as she knew Hulk and Batman were close. Hulk nods and gets in his Hulkmobile, though Karen asks if he'd like some company, to which he says he does. She smiles cutely as she gets in the Batmobile with him, and he takes her to his place. She then seduces Hulk and the two have sex.
