I've been through a lot of trials and errors for this one.
Paint : my first choice of paints did rub too easily, I had to try several ones and do multiples coats.
Head : I wanted to mod Baroness' head but the sculpting and dremeling went wrong.
Legs : they got damaged while pulling the figure apart.
Anyway, I needed a Kitty for my mid-80s X-Men line-up and she fits quite well (note she's wearing knee high boots as JRJR drew her, later pencilers would give her lower boots).
Recipe :
Head, lower legs : MU Kitty Pryde (painted mask, sculpted kneepads)
Body, upper legs : ROC Baroness (sculpted forearms)
