Another goddess from comics that has stolen my heart. Man, Phantom Babe... er, I mean, Phantom Lady is a winner. Forget about her being part of the Golden Age times, she can be brought to the present and be a threat to any baddies from the present day!
Not to mention she's Golden herself, ain't she?
Oh, and since you say she's competition for Power Girl, how about you have them in the same drawing? Maybe as a team-up or something like it. I think it's worth a try, don't you think?
