Let's face it whether you want to admit it or not (though admitting it would be helpful here) we all have had that one character who you just find yourself attracted to. Whether it be because of certain... assets, because you have deep respect for a character, or you genuinely attracted by their personality everyone has one. Now whether you feel you've grown out of this or not, we've had one at some point and now it's time to give them their time in the spotlight. So in the interest of fairness I'll start.
Mine is Supergirl, Kara Zor-El, the post-crisis/pre-new 52 version.
