So I am more of a Batman's fan, so I don't really know all that there is to know about Supes, anyway. Is there any difference between Power Girl and Supergirl? I never understood it, like Power Girl is a different girl? Kara from another dimension? Did they ever coexist, actually LIVED even interacted with other Superman's Family's members? Like Superboy (I know that Supergirl did, but did Power Girl?).
