Originally, the Alternators Dodge Ram mold was intended by Hasbro to be a completely different character altogether than Optimus Prime (which character is unknown), but Takara reportedly demanded the Ram be made into Optimus out of fear that the toy (whose vehicle mode is scarce in Japan as a real vehicle) wouldn't sell as well in their market if it wasn't a popular and easily recognized figure; as the figure reportedly cost twice as much to build as the others, Hasbro had to agree in order for Takara to continue fronting part of the production cost. In an ironic turn of events, the Dodge Ram was prematurely solicited by Takara not as "Convoy" (Optimus Prime), but as his Masterforce look-alike Ginrai. As a matter of fact, the head sculpt for the Alternators Oprimus Prime toy is based on the Super Ginrai (Powermaster Optimus Prime's "super mode") toy's head sculpt. Ultimately, however, Ginrai was cancelled, with only Hasbro releasing Optimus Prime as originally planned. Eventually, Takara released the Dodge Ram as as part of the new Kiss Players line, now named "Convoy" (Optimus Prime), and he will be released in Binaltech this year.
This Japanese-exclusive vacuum metalized golden redeco of Super Base Optimus Prime, whose name means "Shining Golden", was available as a prize in several draws, including a colouring contest held in the pages of TV Boy magazine, and in-store lottery draws at Tobu Department Stores. Between the draws, at least 58 "Kinpika" Prime toys are known to have been given away, making it one of the more widely available Lucky Draw figures, comparatively speaking. It came packaged in a plain white box, and including all the accessories and features of the standard release of the figure, including a gold-chromed Sparkplug (or "Prime", as he's confusingly known in Japan).
A Deluxe class toy of Prime in his Protoform stage. One of the first released movie figures, Prime's Entry Mode resembles a huge metallic asteroid. With this figure standing 5.5 inches tall and Optimus being 28 feet (336 inches) tall, the toy is about 1/61 scale. This rock-like alternate mode has led some fans to sarcastically refer to the movie protoform toys as Rock Lords.
Most notably in terms of new tooling, the panels on the undersides of Powermaster Optimus Prime's forearms feature slots under the fists, which allow the guns to tab in and be held much more stably than with Ultra Magnus. And due to the amount of empty space in the cab area in vehicle mode, Powermaster Prime can fully transform without the need to remove his head.

In robot mode, like Combat Hero Prime, the bottom of the truck became his familiar windowed chest based upon the original Optimus Prime toy. His main gimmick was light up LED headlights, and a lightpipe in the bottom of his right fist, illuminated by an LED in his right forearm, that would illuminate his clear sword or his double-barreled rifle if they were used in that hand. All three LEDs were activated simultaneously by pressing the sunroof-like depression on the roof of the truck.
