SUPERGIRL
As of this writing Mattel has already made a new 'grown up' version of Supergirl (that's what I get for waiting too long to update my site.
A standard JLU female body base was used. The head came from a Supergirl from the 'Superman the Animated Series' line. Her skirt is sculpted, sculpting was also done on her hair. The cape is a modified Superman cape.
