I may have said something that could be misunderstood... I personally don't that she would be too similar to Wonder Girl, but newer fans and people who don't know that much about the DC universe in general might not see the difference. At least not until we get some more origin stories. So far we don't know very much about the WG from the show, except from what fans know already. And if Supergirl got introduced too, we would need to get her story as well. No, i don't think they are very similar, but many of the people who watch the show could be confused by TWO blonde flying girls who hit things  hard.
