Optimus Prime

Variations: The first release of the Hasbro version of Optimus Prime included tabs that restricted the arm articulation of the Super-Mode Optimus Prime configuration. This was corrected as a running-change over the period this toy was produced. Subsequent issuances of the mold do not have the articulation reducing tabs.

There are significant variations between the US release of Optimus Prime and the Japanese MD-01 Convoy. The Japanese version features yellow detailing in contrast to the gold paint applications of the US version. The Japanese version also features a spoken phrase upon pressing the Autobot symbol on the chest.
