Well, it seems that when it comes to gaining weight, Amy tends to gain mostly in her chest area (who knew?), whereas Rouge... erm... doesn't :P

I guess our favourite Bat Girl is no longer the owner of the largest breasts in Sonic's Universe. And Amy seems to be more than pleased by that fact ;)
Actually, considering the fact that Rouge mostly uses kicks and flips while fighting, a more "prominent" lower posterior seems to fit her well, in my opinion :)
