Released as part of the "W Convoy" campaign ("Double" Convoy, that is!) alongside a silver chrome version of Energon Rodimus, this gold chrome "Mēki" ("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.
Released as part of a collaboration between Transformers and Primitive Skateboarding, this figure is a black repaint of the Titans Return Powermaster Optimus Prime, with the deco somewhat resembling Nucleon Quest Super Convoy, but with some gold trims and Primitive Skateboarding markings partially designed by Primitive Skateboard founder Paul Rodriguez. He also comes with an extra ramp and skateboard accessory that resembles the one Daniel Witwicky used in The Transformers: The Movie, which Shreddicus Maximus (or any other Titan Master) can attach to. The ramp can also form Optimus Prime's gun.
Optimus was checking up on the Autobots' ongoing energy collecting campaign when Wheeljack informed him that a disturbance in Sector 33HM of space-time would eventually cause major problems in its time-stream. Optimus assigned the investigation of this disturbance to Bumblebee, then noted that Hot Rodimus had not completed his latest report, communications with the young Autobo having been lost while he was on his own mission. With a brief inspirational speech, he urged his subordinates to redouble their efforts in maintaining harmony throughout reality. Little did Optimus suspect that in his own universe, Megatron was planning a coup against the Autobots... Uprising
Optimus was providing cover-fire for a cross-universal battle when he suddenly seized up. Though he rebooted momentarily, he had terrible news for his Protector allies: using the power of the lower-dimensional Planicrons, Megatron had succeeded in sundering the Alternity's aggregate! Optimus urged his subordinates to not lose hope however, reassuring them that events were still unfolding within the parameters they had foretold. Sure enough, the battle swayed back in the Autobots' favor when Thundercracker, disgusted by Megatron's reckless use of their power, freed the Planicrons and robbed Megatron of his most powerful weapon. Optimus then tasked Elita Seven, the black Convoy, and Bumblebee to track down the doorway that would allow the Planicrons to ascend to the higher-dimensions, putting them on the path to supersede the Alternity as multiversal protectors. While they attended to this task, the rest of the now-former Alternity busied themselves by destroying Megatron's auto-avatars, weakening the villain and disallowing him from interfering further with the Planicrons' destiny.

The second known version  ditched the triplechanging gimmick on the cab and simplified things a good bit. This Powermaster Prime has several distinct characteristics only seen in the second design, such as the wider "block head" and two faux smokestacks on top of either shoulder as opposed to one. Also, in a rather odd twist, this design features a black head and fists for both super and regular modes rather than the traditional blue. It also had yellow eyes in either mode a la the original Optimus Prime.
The Autobots helped repair a Smitco Oil Refinery site which the Lazarus-controlled Transformers had attacked. Optimus had no answer for Spikes accusation that the Transformers' presence on Earth was responsible for the destruction. When Megatron's activities at Lazarus's base were spotted by the military, Optimus insisted on the Autobots going in without backup. They discovered Megatron in the middle of a plan to reformat Earth into a new Cybertron using a cyber-virus. Optimus rejected Megatron's suggestion he should just let it happen, but while the two factions fought, the human military unleashed Operation Clean-Up, dropping a bomb on them. Prime Directive #3
After weeks of Decepticon silence, Optimus Prime decided to get proactive and sent out patrols all over the planet to try and flush the villains out. None of the patrols reported back with any success, however, and Prime realized that there was one area of the planet that his troops had deliberately ignored: the mysterious "Nebulos Triangle". Quickswitch, Scoop and Quickmix were sent into the Triangle, and they did indeed discover and foil the Decepticon plot going on in the area. Decepticons Underground
The TakaraTomy "Autobot Alliance" release of this toy has some significant differences, including casting the red plastic in a darker shade, making his shin and wheel joints grey rather than Hasbro's bronze, painting the Matrix of Leadership silver, and swapping out the dual energon swords for battle hooks, similar to 2010's Leader class Optimus Prime. However, due to the Japanese release retaining the Hasbro packaging, the box still advertises the dual energon swords rather than the hooks. He retains the masked face used for the Hasbro release.
