I don't know if this counts, but I remember Mistress Mary from JLA Classified #8 (2005):

Based on the story title I guess this is some sort of evil doppelganger. From Earth-3, perhaps?

Yeah, that looks like the evil version of Mary from Final Crisis. I doubt that's a coincidence.
To be fair I think in that particular image it's much shorter than it was depicted as in other comics, although I wouldn't say it was that much longer than Post-Crisis Kara's mini-skirt (though admittedly she wore shorts under there).
How do you all feel about the crazy ass team Shazam's put together for his Future State Book?
