Was really lucky to find the last piece based on a fellow collector’s sighting in Singapore! I never had a chance to play with the original Optimal Optimus. I did however, love my Primal very much and fiddled with that weird Transmetals 2 toy with the skateboard. So with that in mind, I will just briefly describe my first hour with the toy. Optimal Optimus: Articulation is very good. Due to the size of his feet, together with ankle tilts, you get a very steady bot mode. It can definitely hold many different poses. I would say just based on this mode alone, the price of admission is worth it. Again, I have never played with the original so take that as you will. Backpack can be an eyesore to some though, it being a rectangular block there. Matrix is surprisingly detailed. Monkey with skateboard: To be honest I never understood the skateboard heh. Monkey’s leg articulation is hampered due to his short stumps. With the skateboard as a backpack, articulation of the legs are worsened, as the length of the backpack obstructs the backward movement of the legs. Mini Primal: Mini Primal is... a nice homage. Again, facesculpt is great. However, even with double hinged knees, his thighs and shins feel like stumps. Even when he transforms into that skateboard space craft, his feet weirdly sticks out at the sides. It just feels like they rushed out his bottom half and it inadvertently affected the other modes. The damn weird spaceship mode: I could somehow squeeze in a headmaster lol. I don’t have much to say about this mode because it feels reallllly tacky. In summary: With its flaws, this toy is still worth buying if you constantly play with all the gimmicks. There really is a lot of play value in each of its modes. At the very least, you get one mini Primal and a Monkey, which can combine to form Optimal Optimus which is large and has a commanding presence. If you are irked by half-assed modes combining to form a nice big robot with a half-assed backpack, then stay away. I personally am having quite a bit of fun playing with it/them.
