I've tried to get this out in the other thread but I get angry replies. How is Power Girl more? What is Power Girl's central story? Why do we need an older Supergirl? Why should we get rid of the original teen blonde DC super-heroine because of others? What makes PG valuable? What makes SG unnecessary?
Why replace a merchansing success across various media with a character that sells fewer comic books and nothing else? It doesn't make sense.
