How many Supergirls...

I remember some interview saying 'around 15' and 'same age as
the younger generation of the Teen Titans'.

She looks like she's about 20, though.

Without having read it, it sounds like this would probably be my take, but written in a coherent manner.

"This project illustrates the pros and cons of working within the DC universe. After decades of appearing in multiple comics, the DC superheroes have acc.... "

And I answer that, with this.

Age was told by Jeph Loeb himself in an interview. At best, she's on par with Wonder Girl.

Who's 15, right?

IIRC, yeah. I know Robin is about 16, and Superboy is (biologically) around that age as well (even though he got hatched only a few years ago). And yeah, Turner's Supergirl looks *at least* 20. But then again, every female Turner draws looks about 20.

The way I see the Titans, Victor Stone is around 27, Koryand'r is around 25, Changeling is around 20 (or he should be), Raven should be around 26 (she was about the same age as Wally West), Tim Drake and Conner Kent are around 16-17, Cassandra Sandsmark and Bart Allen are around 14-16.
