Robot mode

In robot mode he looks exactly like Optimus Prime from the original show. From his head, arms and waist down to his feet, he has articulation that most action figures would be jealous of. There is even a button on the back of his head that moves his face plate up and down.

His elbows and knees have hydraulic joints, and his leg vents open when he stands. Details like these put him above all previous Optimus Primes (except the first, of course).
