I took an original Generation 1 figure, but mixed in with a variety of parts, giving him improved articulation. Grimlock's now got articulation at his shoulders (via ball joints), elbows (hinge joints), hands (hinge joint) hips (ball joints) and knees (hinge joints) I also made a 'slide' for Grimlock's head in robot mode. I've always felt it sat back too far on the top of the chest. This head also is on a peg joint. Lastly, I added some small details to his lower legs to better represent the cartoon images. Grimlock was base coat painted with House of Kolors and detailed with Testors Model Masters (enamel) This version of the Dinobots, I went with a more metallic gold rather than the cartoonish yellow-gold used on the last set.
