I suppose it would be a good time to list the possible ways it could improve over its predecessor, MP-01/MP-04. Now, don't get me wrong, I enjoy MP-01 immensely as a display piece, but he does have some very glaring faults. While he was the pinnacle of Transformer design, possessing a decent blend of gimmicks and articulation as well as an impressive transformation, it's been a while, and a lot of the things that made MP-01 a Masterpiece are also a hindrance. I'm a fan of Diecast when it's used effectively, but this Prime has so much on him that he's nearly impossible to stand. The massive block of Diecast in his torso has to go, or be minimized. The same goes for the legs- the joints in the knees could not support the weight of those things which severely hindered his posing. His joints, of course, are another thing that needs to be worked on- the knees were beautiful in design but supported very little weight and were unstable because of their build, and the pelvic joints were weak- partly because of the weight they carry on the legs, and partly because they did not lock in well. The arms were fairly decent- I don't really have any complaints with them. The transformation of the figure, while complex and interesting, had its flaws. The leg-retracting gimmick was very weak and, compounded with the weight of the upper torso, did not hold well. The head was too awkward to fit in the designated compartment. The pieces that formed the lower torso were also awkward to work with. I know it seems like I hate the MP-01 mold, but I don't. It is one of my most prized Transformers and stands proudly on a shelf by itself. But frankly, with all of the cool things that it can do, all it is really able to do is stand. Posing is tough with this mold, unless it's an epic standing pose. I love the Matrix, the Energon Axe, the gun, and the faceplate, but there's very little this thing can do aside from be a display piece. I guess what I'm getting at is that more recently, the Masterpiece line as been more about articulation and design with less of an emphasis on Diecast, which frankly, I think is a step in the right direction, especially for this new Prime mold. We've changed a lot over the past couple Masterpieces, and it's time we had a Prime that reflected the positives of those changes.
