Korg - Toy Biz style.
He's obviously a Thing base but I modified the head, not only raising the cranium but saving down the jaw and chin.
I also made him taller cutting him in half and adding in a couple of layers of craft foam at the waist and under the feet, so to keep him proportional I lengthened his arms too at the wrists. Real leather and Bishop's shoulder pads to finish the look.
