Batgirl is the favorite character of my second daughter. So I tried to make one for her, carefully working the joints so it can be more playable than some other customs...
Upper body : MU Emma Frost
Head, hands : Microman Batgirl
Legs : Captain Marvel (Carol Danvers)
Belt buckle, pouches : MU Commander Rogers

I think the hands are a bit too big but they'll be useful to hold accessories (instead of "magic spell" hands of Emma Frost).
