This is old news but I didn't really take a close look at it until a few days back. This is by far the most superior Optimus Prime ever. I am not comparing vis-a-vis with MP-1 but from the movie line, this is the best and most complex.
Totally confusing "transformation sequence" which left my Prime in its robot mode. I am not going to transform it into the vehicle mode, for fear of not being able to transform it back to robot mode.
The ion blaster is awesome. Huge and deadly. And Prime is all chromed-up.
My only complaint. The mouthpiece. Apart from that, this is one bad-ass robot.
