This is a “Club Grayskull” Trap-Jaw figure I was asked to do some custom work to.
For this one I was asked to fill in the articulation points on his left shoulder, elbow, wrist, torso, upper legs/crotch, knees & ankles.
This was all done with a product called ‘Fixit Sculpt. The figure was then repainted using enamel paints.

All of his weapon attachments can still be used but I was not sent any with the figure so that is why they are now shown in my photos.
