Is that Power Girl on the left?
Power Girl is all natural.
Now, how she happens to be the same person as Supergirl but have twice her boobage, I just couldn't tell you.
Oh, I know PG is all natural. But lacking context, I thought it could be a case of Supergirl just being catty. "So THAT'S why they're so much bigger than mine!" Besides, it looks like PG's bob haircut.
Does X-ray vision even work on someone who's invulnerable?
