Released as part of the "W Convoy" campaign ("Double" Convoy, that is!) alongside a silver chrome version of Energon Rodimus, this gold chrome "MÄ“ki" ("plating") version of the Deluxe size Optimus Prime toy was available only as a prize in a mail-in Robot Points contest. Initially limited to 20 units in the original draw, it appears that many more were made available through toy store drawings, given how many went on to appear on online auction sites through 2005 and 2006.
A fourth version is shown in the 1987-88 Transformers product catalog that has several minor differences from both Powermaster Prime and God Ginrai, such as having God Ginrai's sliding fists but in red, a completely different trailer hitch assembly partially based on the third design, an offset Autobot symbol in base mode, extended feet also based on third design, far more detailed super mode outer leg panels, completely different front bumper, and the first instance of single faux shoulder smokestacks rather than two. It is still unknown as to why Powermaster Prime has completely different arms from God Ginrai or all earlier concept versions.
The earliest releases of Energon Optimus Prime have no ridges on the inside of the chest windows and a different head sculpt featuring an Optimus Primal-style mouth-slit in Prime's mouthplate. This was soon replaced with a full mouthplate, and it was this version of the toy which appeared in the Energon cartoon and was released by Takara. Other changes made to Takara's version of the toy involved a chromed front grill, more vibrant plastic colors on Digger-3 and Submarine-4, a darker blue plastic on Prime himself, and more intricate paint operations. Takara's release lacks the electronic sound effects seen in Hasbro's version, which were commonly gutted for the Japanese releases of any Autobot toys who had them, though Prime retains his light-up chest.

Rodimus appeared in the text-based fiction Dungeons & Dinobots as one of the Autobots who attacked the Arch-Ayr fuel dump. Sent to capture rogue Dinobots for the Autobots, he was part of the group that captured Swoop. Together with Blurr, he then tracked Grimlock, but ran into competition with the Decepticon allies Sideswipe and Cliffjumper. After Grimlock bit off his left hand Ratchet replaced it with a circular saw (a reference to one of the original Rodimus' melee weapons in The Transformers: The Movie).
Optimus Prime is composed of two parts, his truck cab and his trailer. His new truck cab is reminiscent of the original Optimus Prime truck cab, but is constructed entirely of plastic, lacks vacuum-metalized plastic and has no clear windows. It also transforms differently in that the front of the truck is no longer the robot mode's chest. His chest is now formed out of the truck's cabin rear, styled after his cartoon appearance. He is armed with two long black rifles, based in part upon his cartoon rifle.

The figure's transformation scheme is based on the original G1 figure, the only differences being that the fists are not removed but become the headlights, and instead of flipping backwards inside the chest, Diablock Convoy's noggin flips forwards with the aid of opening chest windows. A "laser rifle" in the shape of his ion cannon can be built from black bricks, and stickers bearing the Autobot faction symbol can be placed on his shoulders, although this is not recommended as it is designed to permanently stick to multiple tiles which dislodge easily and may damage the sticker.
After the Great War, Optimus Prime disappeared with other legends into the mysterious location on Cybertron dubbed J'nwan, where Optimus himself became the "Authority" who spoke on behalf of the others. Sandstorm, the leader of a rebellion in a 32nd-century firmly under the heel of the tyrannical Shokaract, entered J'nwan to plead with the heroes of Cybertron's past for aid. He hoped to convince them to join the fight against the Predacon warlord. After a mind-crushing journey which left all of his companions dead or deranged, Sandstorm finally found an audience with the Authority and his brethren, but they declined to help, with the Authority stating that their time was past and the war was no longer their war. The Authority then in some way manipulated Sandstorm's trip out of J'nwan such that it was comparatively short and simple. Paradox
A Voyager class figure that transforms from semi-trailer truck to robot. Head features retractable face plate. The figure's main gimmick is a spring-loaded mechanism that spins the lower torso during transformation to robot mode. Trailer detaches and transforms into a giant Ion Axe or jet pack. Prime's gun can be filled with a small amount of water. Some variants of the figure come with the Autobot symbol printed on his left shoulder while others do not.
Optimus Prime is the fictional protagonist of the Transformers: Robots in Disguise (Fire Convoy in the original Japanese version) branch of the Transformers universe.[38] Based on the character of the same name, Prime once again leads the Autobots against the Decepticons. His voice actor, Neil Kaplan, does his voice in a style reminiscent of that of Peter Cullen, the voice of the original Optimus Prime. Wired Magazine nominated Fire Convoy as one 12 most ridiculous Transformers ideas of all time.[39]
