Every now and again I can't help getting interested in these teases. Especially when I think I know what they are.
This was the first one and while it could be Flash I remember hearing a rumor about a Teen Titans line being done. So maybe Kid Flash? Then this one turned up the next day.
Blond hair...only a few characters come to mind in the new 52 and if the TT rumor is correct then Wonder Girl. I'm not sure if they'd tease each figure since I think they more or less focus on one at a time. The first image doesn't look like a part of her costume which makes me wonder if their showing all of them. Of course I'm usually wrong about these things so it'll probably be someone like Supergirl.
