Comicosity has a preview of Suicide Squad #27 which features Power Girl; as I don't get the monthly title but am a fan of PG, I thought I'd head over there and see what was happening without worrying about spoiling any surprises - like I said, I don't get the title so no worries.
Here's page 2 of the preview:
Dear Lord, the poor woman has no spine! I'm not an artist or a biology student but even I can clearly tell that people do not bend like that! And her legs - surely her right leg (the one closest to us) should be bent at the knee to help support that weight?!
Definitely one of the boobs and butt tag of EscherGirls, I think.
