If you’re just a Lego fan with no connection to The Transformers, then it’s a more difficult question to answer, but the fact that Optimus’ engineering allows it to transform so smoothly is an innovative feature that no other Lego set provides, at least certainly not in such a polished fashion. If you’re just a fan of toys in general, then the historic nature of this team-up between Lego and Hasbro is also a powerful reason to purchase Lego Optimus Prime. If you’re a Transformers fan, then the answer is obviously yes. Optimus Prime has hands sufficiently articulated to give the thumbs up. He literally – by the invocation of swivels, hinges, twists, and turns – transforms into a truck, and the transformation is pleasingly more involved than we thought it would be. But, all of these issues fall by the wayside when you consider the remarkable fact that Lego Optimus Prime transforms! And we don’t mean that you can dissemble the robot and rebuild the bricks into a truck. What really hammers home the fact that this is not an action figure, but rather a model to be displayed, is that sections of it have a tendency to fall apart when moved. However, the axe is too heavy for his arm to hold aloft, causing his arm to sag, so Optimus can’t really be posed with it raised above his head. To wield his energon axe, his hand can swivel out of the way, revealing a hole into which the axe’s Technic rod connection can be inserted (this makes it look like the axe itself is emanating from the end of his arm, just like in the cartoon).

Optimus’ ion rifle attaches to the studs on his arm, allowing his hands to loosely clasp the handle without the gun dropping from them. The hinged radiator grill and flaps containing the headlamps create a tapered midriff, avoiding the design becoming blocky. His upper body has more articulation – a 360-degree waist swivel, 360-degree shoulder joints, a 90-degree hinge at the elbow, wrist swivels, a neck swivel, and a neck joint that allows him to look up, though this is part of the transformation and isn’t particularly aesthetically pleasing. He does have ankle rockers, which helps somewhat with posing. Posing Optimus Prime is limited because he has no knee joints, presumably for stability reasons – he is heavy, and Lego don’t have any plausible connections in their inventory that could act as knee joints and carry Optimus’ weight for long without sagging. We think it really looks the part, but here is where we have to remember that this is a construction model and not an action figure.

The finished robot is big, standing 13.5 inches (35 cm) tall and towers over his original 1984 incarnation. Comparing the Lego Icons Optimus Prime (left) with Masterpiece MP-10 Optimus Prime (middle), and the original G1 Optimus Prime (right).
