Refractor and Laser Prime were only available in a box set named "Chaos on Velocitron" that includes Dynamus and Quickswitch, Parsec and Autobot Nautica, Fastclash, and a Rodimus Prime Titan Master head. The set was officially announced by Hasbro to be a Toys"R"Us exclusive, and was sold at stores in the United States, Canada, and Hasbro's Asian markets (such as Malaysia, Singapore, and Hong Kong). Despite this, it later became available via Amazon in the United States (but not in Canada) as well, actually sold by Amazon directly (as compared to a third-party seller).
The actual events of the Autobots and Decepticon coming to Earth were never printed by Dreamwave comics, but flashbacks of the events are printed later. These flashbacks suggest that the Autobots allied with humankind and defeated the Decepticons at the turn of the century. They planned to return to Cybertron aboard the newly constructed Ark II, but the ship was destroyed as part of a military conspiracy to take control of the transformers. A terrorist organization, run by the enigmatic Lazarus, was able to seize control of several of the Transformers that fell back to Earth while the U.S. military was occupied with locating Prime's body. Before his departure, Prime had entrusted a small portion of the Matrix to Spike Witwicky, who was forced by the product chief, General Hallo, to use it to reactivate Prime. Functional again, Prime used the Matrix to reactivate more of his fallen comrades, and then faced off against Megatron in San Francisco.
As with all Action Master toys, Optimus Prime himself could not transform. His sculpt is based heavily upon the The Transformers cartoon model, though the colour scheme may be based upon his Powermaster (pre-supermode cab robot only) body, with blue forearms as opposed to just blue fists, although unlike the Powermaster cab robot it has blue thighs as well. His truck cab vehicle and the trailer do transform, though neither have robot modes. The truck cab can transform into a small plane, while the trailer transforms into a battle station with turrets that several Action Masters can man.
As this is the Unicron Triogy we're talking about, it should come as no surprise that Prime can transform into a Super Mode by combining with his trailer, which becomes a massive winged backpack and a pair of large boots, generally evocative of God Ginrai. To complete his Super Mode look, a small lever of the back of Prime's head raises his traditional mouthplate into place, covering his Optimus Primal-style mouth slot, and two "crests" fold out from either side of his helmet. Hasbro's instructions and stock photography for the figure orient the wings so that the two cannons point over Prime's shoulders, but Takara's have wings arcing up past his shoulders, with the cannons slung under his arms. This was the way Prime appeared in the cartoon series, and was the way all subsequent Hasbro redecos of the toy were positioned. In Super Mode, Prime is a rather top-heavy robot, and his hip joints are not that tight, which makes standing him up a challenging prospect.
Rounding out a bumper year of Japanese-exclusive Generation 1 Optimus Primes, the Takara-licensed Kawada brand Diablock Convoy is a fully transformable Lego-style block building figure similar in premise to the earlier American Built to Rule sets. The Diablock figure, however, easily outstrips the Built to Rule sets by both being an accurate representation of the toy on which it is based, and being able to transform between modes without having to be partially disassembled and put back together first.
Originally, Optimus Prime was created as the leader of the Autobots, though it is unknown how he was created or his origins. In a possible future, Megatron was threatened by the existence of the Aerialbots and had Shockwave build a time machine to send them back in time to get rid of them. However, he only ended up changing history for the better. In the revised timeline, Optimus Prime began his life as a robot named Orion Pax, a mostly defenseless dock worker during the Golden Age of Cybertron nine million years ago, with a girlfriend named Ariel and a best friend named Dion. During this time, a new breed of robot with new flight capabilities appeared on the planet that Orion idolized. When Megatron, the leader of the new group of robots, approached him with inquiries about using one of the dock warehouses, Orion was swayed by Megatron. Both Orion and Ariel were severely wounded when Megatron and his forces attacked in order to claim the energy stored there. Searching for someone to help them, the time-displaced Aerialbots took Orion and Ariel to the ancient Autobot, Alpha Trion, who used them as the first subjects for the new reconstruction process he had developed involving rebuilding the frail Autobot frames into more battle-hardy configurations.
