And it can't be excused by saying "oh, she an alien and might really be a hundred years old". Miss Martian views herself as a teenager and that's how she represents herself. Also Mary Marvel and Supergirl were both at least 16 and very human and it seems like every issue with them (for Mary in Countdown, for Kara the first 20 issues or so of her own title) had some kind of panty shot. I'm sure there's some of kind of underage fetish out there these artists are catering too but DC (and Marvel) have plenty of 20&30-something heroines they could use instead - and usually they don't. That's what offends me the most.
