As you all know, my Dev Custom is non-transformable. In that case, I really had to focus on hard core durability and the paint applications. So here is Mixmaster. I decided (with help from a couple polls - and thanks to those who participated) to go ahead and add the energon sludge effects. He appears to be separable now but when all parts and figures are fully painted and complete, I will go ahead and permanently attach him while keeping his many, many points of full articulation and posable preferences. Thanks for checking him out!
