Hasbro's Toys R Us-exclusive 2003 reissue of Powermaster Optimus Prime was actually a modified version of Takara's then-recently reissued God Ginrai set. As such, the cab was partly constructed out of die-cast metal, vacuum-metalized plastic and had clear blue windows. The trailer was retooled so the super robot's fists could slide in and out of the arms. This set also included the originally Japanese-exclusive Apex Bomber drone trailer that attached onto the back of Optimus Prime's trailer in vehicle mode, and could become extra armour in super robot mode.The missiles where unchromed and lengthened due to safety issues as opposed to the Japanese release which were chromed and shorter.
This release of Buster Optimus Prime was susceptible to a paint scraping issue on the silver painted slide-out barrel of his blaster. This problem was fixed for the DOTM Re-release by relocating the silver paint app from the barrel to the inside wall of an exposed gas tank that had been previously left as unpainted grey plastic. The black paint app on the barrel was left unchanged.
In our list of things you didn’t know about Optimus Prime, we learned that the live action version of Optimus was based on actor Liam Neeson. It turns out Michael Bay likes to base his Transformers on real actors, because it’s been revealed that Bumblebee’s character movements are based on Michael J. Fox-- but not just regular old Michael J. Fox; we’re specifically talking about Marty McFly in the Back to the Future movies.
In "Mission Accomplished", Optimus is pressured by Sentinel to tell Ultra Magnus that his story about the Decepticons is untrue, but he refuses. Meanwhile, the on-board computer plots a train infused with a shard of the Allspark. When Ultra Magnus and Jazz set off there, Optimus suspects that the Decepticons are luring them into an ambush and rushes to their help, though Sentinel Prime tries to detain him. At first, Ultra Magnus doesn't believe him, but a short time later, Optimus is proven right as Starscream falls from the sky after being blasted by Megatron, much to Sentinel Prime's astonishment and fright. Starscream turns out to be alive, inflicting injury on Ultra Magnus. Optimus takes the affair into his own hands momentarily and, with Sentinel's aid, manages to apprehend the Decepticon. While Sentinel Prime deflects Starscream's shots with his power-shield, Optimus succeeds in taking Starscream by surprise and handcuffing him. When the shackled Starscream is delivered to the Elite Guard spaceship, Ultra Magnus admits Optimus Prime was right and allows him to stay on Earth in order to seek out the other fragments of the Allspark.
The earliest version, as shown in the first patent application for the toy, was to have the Prime cab be a triplechanger, turning from truck cab to jet or robot. The nosecone of the jet and robot legs were released by the Powermaster lock in the same fashion as the legs in the final version. Optimus would have had winged arms in non-super robot mode. The super robot mode's head was also integrated into the trailer's hitch... and lacked a faceplate.
Commemorating the death of Optimus Prime in The Transformers: The Movie, this set contains a special version of the original Optimus Prime figure with show-inspired translucent blue windows. It was packaged with Ligier and Alert, in an apparent homage to the similar Diaclone "Powered Convoy DX" giftset that packaged the "Powered Convoy" version of the Optimus mold with figures using the molds of Ligier and Alert.
A redeco (or should that be de-deco?) of the Grand Convoy Super Mode Pla-Kit, Grand Convoy Super Mode White Version was available exclusively on July 17th and 18th at the Japanese convention, Kodansha Super Chara Festival 2004 ("K-Fest"). It is a solid white version of the normal model kit, possessing all the features of the normal figure, which was intended to be used in a customization/painting contest held at the convention. It lacks the comic of the normal release.
Unlike the other Swordbot toys, Optimus Exprime's kabuto helmets form an integral part of one of his alternate modes. The kabuto helmet designed for use with his DaiGekisou combination forms the head of his dragon form, while the kabuto helmet designed for use with his DaiKenzan combination forms the "tail" of the same. He comes with two HUGE swords (with 5mm handles) which can be attached to several places on his kabuto helmets or either alternate form, held separately in his hands, or held both in the same hand (with one held in reverse-grip).
Once combined, DaiKenzan has three new phrases (spoken in Kenzan's voice), while DaiGekisou has four (in Gekisoumaru's voice). In either combined form, pressing and holding the button activates an additional, longer phrase for their "final attack". DaiGekisou is armed with a scissors-esque "shuriken" made from combining Optimus Exprime's two swords, while DaiKenzan simply wields them separately.
The figure would have come in a monochrome version of the standard Henkei! Henkei! Convoy's packaging, still named "Convoy" but now labeled as part of the Gentei! Gentei range of exclusives. Reportedly, this figure was intended as a Wonderfest exclusive, but was canceled because, according too TakaraTomy designer Shogo Hasui, it was too similar to Universe Nemesis Prime. Knockoffs were later made available, so buyers beware!
In the two-part episode "Megatron Rising", Optimus loses his composure over the recent numerous Decepticon attacks coupled with the fact that Prowl had secretly placed the Dinobots on an island off the coast of Detroit instead of destroying them. He has Ratchet confiscate the Allspark key from Sari, which he loses when he is ambushed by Blitzwing. Optimus also fails to stop a newly resurrected Megatron from acquiring the Allspark. He defeats Megatron by overloading the Allspark in his chest with Sari's key. In the process, the Allspark shatters into countless pieces, scattering all across Detroit.
In 2007, the Optimus Prime of universal stream Primax 109.0 Beta encountered a mysterious messenger from another world: another incarnation of himself from a parallel dimension who left him with a warning. Two years hence, Megatron would bring the terrifying super-dimensional lifeform known as the "Beast of Time", the Hytherion, into their dimension to destroy Earth. The only thing that could battle the Hytherion was the power of the super-evolved multi-dimensional race of Cybertronians known as the Alternity. Prime agreed that when the danger appeared, he would join the Alternity in the fight.
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.
