So I have seen several versions of Power Pack with Energizer usually made from a different base. The explanation I recall is that it's too difficult to get her down to the correct size. It is true but since I had so many X-23's to use I trimmed her down is the lower legs where Lightspeed and Mass Master will not be. There is a slight difference but not sure if that will come through is the pics. Energizer is supposed to be younger and has a little more baby/toddler fat-in planning it out I did not think it would translate well to the base so just went with the short aspect. Her braids are from Valkyrie. Zero-G is up next. I'm planning 6 figures for this group.
