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.
Available exclusively at the Tokyo Toy Show 2012 (along with Prime Shining Optimus Prime), Black Optimus Prime is a very minor redeco of the previously unreleased Gentei! Gentei! black version of Henkei! Henkei! Convoy, itself a redeco of the Classics Voyager Class toy. As such, Black Optimus Prime is mostly cast in black plastic, with some gray parts, translucent red windows and teal paint operations.
After their own Optimus Prime disappeared, Scavenger and Smokescreen discovered an alternate version of Optimus Prime lying unconscious and barely alive in Autobase Earth. Though Red Alert did what he could, the mysterious Prime reactivated only long enough to utter a cryptic statement about the walls crumbling and the coming of chaos, then died.

Optimus later led a convoy in search for a building site for Autobot City, which ran into a Decepticon ambush. Rodimus Prime remembers the Transformers greatest battle on Earth. He sent off several Autobots to get help, knowing this was the only chance of victory. Transformers Combat Data Those several Autobots were seen again, but Prime... wasn't.
While the other Autobots searched for the Matrix on Earth, Optimus Prime searched for Vector Sigma, guided through the dangers of the planet's catacombs by the spirit of Alpha Trion. Prime eventually arrived at the computer, only to find his way barred by Cyclonus and Scourge. At that moment, Hot Rod arrived with the Matrix, the same with which Alpha Trion merged, re-energizing it. The Matrix transformed Hot Rod back into Rodimus Prime and, for the first time, the two Primes fought side-by-side and defeated Galvatron.
Each arm features flip-out blades that trigger when a button on the forearm is pressed. Each of these blades has a Cyberglyphic symbol on it. The blades severely restrict Prime's arm articulation when retracted, as they get in the way of the kibble, but as there is very little one can do with Prime's arms without causing the blades to deploy, this is hardly noticeable.
Once again Optimus Prime and Megatron were re-engineered, with Prime now a fire truck and Megatron a six changer, whose modes included a dragon, bat, jet, land-craft and a giant hand. Another G1 character to get a new toy for this line was Ultra Magnus, who could combine with Optimus Prime to form Omega Prime. Other combiners were created for the series too, such as Landfill and Rail Racer. Bruticus, a combiner from G1 was also recoloured and introduced into the series, with a coinciding toy re-release. The Combaticons that formed Bruticus were the first of the Decepticons to be introduced into the show along with Scourge, who as a toy was a black repaint of G2 Laser Prime. These were not the only toys to be re-released for this series, with many from past lines being repainted and packaged in RID boxes. Robots In Disguise was responsible for introducing a lot of concepts that would be re-used often in the next incarnations of Transformers.
Takara's release of Optimus Prime the following year made a few changes, noticeably replacing the gold paint and plastic of the Hasbro toy with bright yellow and much brighter gold. The deco has been tweaked to be a bit closer to the original prototype glimpsed in early catalogs, with yellow added back to cab Prime's feet and the cab grill painted silver, and the Super Mode's waist getting much more paint. This version of the figure was never burdened with the mobility-inhibiting shoulder tabs. Completing the Super Mode combination triggered a new clip of Prime shouting "Convoy, ready for battle!" in Japanese instead of generic mechanical sounds. Late in the run, JUSCO stores offered this toy with blind-packed "Space Galaxy" versions of the individual Destruction Mini-Con Team members, one toy per box.
A slight redeco of Takara's Deluxe-size Optimus Prime was released as part of a special set commemorating both the 20th anniversary of Transformers and the 30th anniversary of its progenitor, Microman. Coming with an exclusive metallic redeco of Takara's Kicker, which was based on the Microman body, this Prime featured a chromed grill where the original had painted plastic, and supposedly slightly shinier plastics. Very slightly.
Optimus and Prowl secretly guarded a shipment of microchips that could be used to imbue sentience onto robots. Posing as the lorry transporting the precious cargo across the Yorkshire Dales, he was attacked by Megatron and Rumble who sought the microchips to create an army of Decepticons. With your help, Optimus may or may not have been successful in keeping the microchips out of the Decepticons' hands. Highway Clash
Optimus Prime is the fictional protagonist of the Transformers: Robots in Disguise (Fire Convoy in the original Japanese version) branch of the Transformers universe. 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.
Part of the first wave of Prime: First Edition Voyager-Class toys, Optimus Prime transforms into a truck, with a similar (but more complex) transformation to his previous Deluxe-Class toy, and features a faux-kibble window-chest panel as well as a detailed truck cab interior. He comes with a "Cybertronian battle sword" and a "plasma cannon", either of which can peg into his hands. The cannon also features a 5mm peg-hole on the underside of its barrel, allowing the sword (or any other compatible accessory) to mount there as a bayonet. They are stored in vehicle mode by pegging them onto either the 5mm-compatible trailer hitch, or onto each peg-hole beside it, although the instructions tell you to peg the sword facing forwards onto the hitch, with the cannon mounting backwards onto one of the side pegs. His trailer hitch ends up on his right robot leg, and he has a fake, sculpted, equally-usable trailer hitch on his left leg. He features a cardboard stand as with all "First Edition" toys, but the weak adhesive used for its flaps mean it often has trouble supporting the weight of a Voyager class figure for an extended amount of time, the top caving in as the glue gives way.
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.
Like the previous Prime, it is loaded with features, though it ditches the first movie's Automorphing for the new Mech Alive gimmick. When a grey tab on his midriff is pressed, Prime's entire pectoral region "flexes", lights in his chest and eyes glow, and he declares "I am Optimus Prime" in Peter Cullen's voice. For the European release of the figure, to get past the language barrier, the Cullen sound clip is abbreviated to just "Optimus Prime"; in some regions, including Quebec and the UK (but only after a month or two), both versions were made available. A transformation sound effect activates when his torso is transformed, and once Prime is in truck mode, an almost unnoticeable button (a small square located beside the screw for the battery compartment, undocumented in his instructions) is revealed, which activates engine-idling noises.
The centerpiece of the power-up robot mode is Prime's gigantic Ultimax Super Cannon, an electronic light-and-sound weapon the size and mass of a Deluxe figure. The whole cannon attaches to a special socket slightly behind Prime's shoulders, can store on the back or flip over to be gripped in both fists in armor mode, or stored upside-down underneath the trailer in truck mode. When pointed forward, the cannon has a larger helmet styled after Prime's own with a large translucent face shield featuring a painted targeting system. The weapon has three electronic modes: each of two small buttons plays its own weapon-firing noise and flashes one set of lights, while the large pull-switch in the cannon's center plays the sounds of a powerful barrage, flashing both sets of lights and (every third time) finishing off with the declaration "I am Optimus Prime". The Ultimax Super Cannon also has two of its own 5mm ports for even more MechTech firepower. When mounted on his back, the Cannon has two hook-like sections that securely lock into the "backpack", allowing the Ultimax weapon to serve as a handle for Optimus' imaginary "flight" operations.
