TF Galaxy Radio #3 We talked with Adam of M31 Designs about his designs and King Kickbutt tf upgrades and weapons. Yul and Ben are on board! M31 Designs: Talks with us about King Kickbutt, head replacement for MP Grimlock. The head is nicely sculpted with great attention to detail and nice interchangeable light piping from red to blue. Grimlock has never looked tougher! The MP crown doesn’t fit this bigger head but a real king doesn’t need a crown. This head looks great! M31 Designs!
