Minor note: Powermaster Prime's animation model as used in the commercials and as a character guide for the Marvel comics is a composite of the second and third designs. The body of the model is actually a straight tracing of the concept lineart for the third version (including its different rifles and twin faux shoulder stacks), with a slightly simplified drawing of the second version's head drawn on top.

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.
The original Optimus Prime toy started life as the Diaclone toy, "Battle Convoy", created by a team of Takara designers who came on board when the original designer fell behind. This team included Hiroyuki Obara (listed as the sole creator on the toy's patent) and famed mecha designer Shōji Kawamori. The toy transforms into two major components; the first component being a red and blue White Freightliner WFT-8664T cabover semi-trailer truck partially composed of die-cast metal, and the second component being a large silver trailer of currently-undetermined model.
Aside from the Powermaster feature itself, the main gimmick of the toy is the ability of the truck cab to combine with the trailer to form the larger "Super Optimus Prime" figure. This is essentially accomplished by standing the trailer up, folding the cab in half and inserting it into the empty cavity in the trailer's torso, forming an imposing—if almost entirely unposeable—robot form armed with all four weapons. The head of this super robot form is a separate piece which can be stored in the rear of Prime's trailer when not in use. While Hi-Q was always shown plugged into Prime's chest in artwork of this mode (as seen in the picture here), this was actually entirely unnecessary as transforming into Super Optimus Prime didn't require the standard Prime toy's legs to be unlocked.
This mold was redecoed into Universe Optimus Primal and Beast Wars Telemocha Series DX Convoy, and retooled into Beast Wars Reborn/Beast Wars Tenth Anniversary versus pack Optimus Primal. Takara also created multiple special variants, including all-gold (from Tele-V Magazine, only ten awarded), red and gray (Tele-V again, but only one awarded), and blue-fur (a Comics Bom Bom design-contest prize, only five awarded).

Like the original figure, Powermaster Prime is composed of two major components: his truck cab, which transforms into Prime himself, and his trailer, which is essentially a heavily-armed version of the original. The trailer has a fold-down ramp to allow the storage of a smaller Transformer, or perhaps spare accessories. The trailer transforms into a battle station armed with two long black rifles and two grey double-barreled cannons (featuring seating for Powermaster engine figures), all of which Optimus Prime can also wield in his fists.
Prime would make one further surprise appearance in Dreamwave's Transformers: Armada series. With Optimus Prime having disappeared to an alternate dimension, devastated by Unicron, the Autobots attempted to find their leader. As Jetfire attempted to locate him through Spacebridge links to other dimensions, one of these clearly shows RiD Optimus Prime and Prowl.
Like some other Legends/Legion Class toys, several of the loose units were dumped in some Hobby Shop dealers in Asia, although this one is very likely to be an identical knockoff of the toy. While the paint applications are pretty much identical to the real deal, the pegs on the legs/trunk front can be a little too tight when attached. in some worst cases; it can break off if attempted to pull off by force.

Exclusive to Walmart, this Deluxe Class Optimus Prime is an all-new mold, close in scale to Voyager Class Megatron. He has a high range of motion, with ball jointed shoulders and hips, swivels at the neck, knees, and feet, and double swivels in the elbows. As a result of the transformation process, he can also rotate at the waist, though this is hindered considerably by his "backpack" kibble. This can be remedied by pointing the truck nose downward, as it is in the packaging. Optimus Prime also features the spring loaded "Automorph" feature in his head, if the truck kibble pushes the small grey switch from his back before splitting the chest into half.

Part of the first wave of Prime Series 2 Cyberverse Commander Class toys, Optimus Prime is a smaller-scale toy, and features translucent plastic for his torso so that the toy can be illuminated using the electronic lights featured in the larger playsets. He comes with two translucent "battle cannon" weapons which feature multiple 3mm posts and ports, allowing them to be held by his hands, or store/mount onto numerous ports on his person. Additionally, he features a 5mm port for a trailer hitch.
Partially constructed of die-cast metal, this small three inch figurine of Optimus Prime has a CGI-accurate sculpt compared to the larger toys, owing to the fact it does not need to transform at all. He is sculpted with his Ion Blaster in his right fist, and is articulated at the neck, shoulders and waist. He comes with a small movie-style Autobot sigil display stand.
Laser Optimus Prime transforms into a mid-1990s Western Star 4964EX, pulling a grey and black fuel tank trailer. The sides of the trailer are decorated with a sticker depicting Prime using a flamethrower to burn down a banner with the words "Optimus Prime Octane" on it. The truck is armed with a disc launcher on the roof of its trailer, which launches five blue discs bearing the Generation 2 Autobot insignia as a knob is turned. Like the other "Laser" toys released this year, Prime features electronics powered by two button-cell batteries; in truck mode, pressing the button on the cab's roof causes his headlight to light up with yellow LEDs.
In robot mode, Voyager class Optimus Prime is proportionally more accurate to his CGI design than the leader class toy and has a more accurate headsculpt, but due to the aforementioned lessened complexity significant sacrifices had to be made, such as "cheats" to the transformation sequence, to achieve this and thus he is overall less accurate than he initially appears. In addition to previously mentioned changes, he carries much of the truck's front hood, grill and fenders on his back like a backpack. However, he maintains a superb level of articulation and posability.
Available exclusively from Japanese clothing company A Bathing Ape in March 2013, "Convoy Reissue BAPE VERSION RED CAMO" (コンボイ復刻版 BAPE® VERSION RED CAMO) is a redeco of the original Optimus Prime toy sporting a unique new red color scheme, along with a red trailer decorated with a camouflage pattern. Both trailer and Prime himself feature the A Bathing Ape logo in place of an Autobot symbol, while the floor of the trailer's Combat Deck mode features new Bathing Ape-themed labels. The figure comes in a recolored version of the original Japanese packaging.
The second known version [17] 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.

Featuring a complex transformation, the front and back ends of the truck essentially fold and converge to become Optimus Prime's legs, as much of the truck rear is connected to the robot thighs via a series of folding panels. The rear wheel cowlings feature a hinge joint in the middle of them so they do not impede his knee articulation. The halves of the rear cabin of the cab, directly connected to the smokestacks, rotate and connect to his torso and unfold into his arms. As with most mainline Movie toys, Optimus Prime features Automorph gimmicks, and due to his price point, he has three of them. Firstly, during initial transformation, rotating his front fenders to become his heels flips the top parts of the grill to become his toes. Secondly, sliding out the double-barrel cannon in his right forearm flips out his spring-loaded Ion Blaster, which lands into place for his right hand. (The Ion Blaster can actually be popped off his forearm fairly easily, as it is held in place by a simple clip.) Optimus's final Automorph, located in his torso, is activated by flipping the silver lever on his stomach, activating a series of spring-loaded actions where the truck windows are pushed apart and the lever between them is raised, enabling the head to spring up from the chest cavity. At this point, yellow LEDs light up the chest windows and Optimus Prime's eyes, accompanied by a "powering up" sound effect.
Available with Grimlock, this Optimus Prime is a redeco (or possibly a repaint) of the figure above, featuring extra paint applications on the chest and thighs, and he features a different flame pattern on his side doors. His Autobot insignia is now tampographed on his right arm. The cyberglyphs on his front hood is confusingly translated as "PRIME". The 2-pack also comes with a card, which the glyphs being decoded as "DINOBOTS". Optimus Prime and Grimlock also saw release as a Toys"R"Us Japan exclusive, making this Optimus Prime redeco/slight retool to be first sold at Japanese markets.
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 sideways-opening windows, akin to Masterpiece Prime. 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 Diablock Convoy's shoulders, although this is not recommended as it is designed to permanently stick to multiple tiles which dislodge easily and may damage the sticker.
In the third nexus, Optimus oversaw Ironhide testing Sparkplug's latest invention, the Sun-Pak, a miraculous device capable of fuelling a Transformer for an entire Earth day after being charged for only an hour in sunlight. As the trial-run wound down to an end, the Decepticons suddenly burst into the Autobots' secret underground testing facility, forcing Optimus to decide whether to order a tactical retreat, or have his Autobots fight the intruders despite his troops' low energy reserves. If he chose to stand and fight, he had the additional choice to either make the Autobots concentrate on Starscream, who is leading the charge against the Autobots, or divide his troops' attention onto all of the Decepticon assailants. If Optimus chose to attempt to eliminate Starscream once and for all, the Decepticon Seeker would beg for mercy, forcing Optimus into a choice yet again: accept the snivelling Decepticon's surrender, or continue his attempt to end Starscream's evil once and for all. Accepting Starscream's surrender spells victory for the Autobots, whereas ignoring Starscream pleas ultimately leads to Sparkplug being kidnapped by the Decepticons, necessitating Optimus to send Buster, Blaster and Bumblebee on a perilous retrieval mission while the other Autobots recharge at the Autobots' home base.
This Optimus Prime is an extensive screen-accurate redeco of the Dark of the Moon Supreme Class/Leader Class Striker retool, using the Ion Blaster accessory from the Buster Optimus Prime and the Toys R Us Japan-exclusive battle blade accessories. He also comes with the Knuckle piece and the Battle Hooks and uses the 2-2-1 articulated fingers featured from the second Asia Premium Series release. He also features a Japanese language sound box for his voice gimmick, replacing Peter Cullen's "I am Optimus Prime" voice line.

Released as part of the first wave of the Energon Igniters Nitro Series, this Optimus Prime is a new Voyager-sized mold that converts from a robot based on his Age of Extinction body into a truck in 11 steps, and he features 5mm-compatible hands & articulation on his head, arms, and only his upper legs. He also features built-in Ion Cannons in this lower leg panels, activated in vehicle mode. He also comes with his own energon core, which is a different mold from his Power Plus toy.


Yet another Reveal the Shield redeco with the Motorbreath retooling, Convoy is cast in clear red and black plastic. He has been retooled to include a magnet in his right foot, allowing him to interact with Lost Age Battle Command Optimus Prime and Age of Extinction Stomp & Chomp Grimlock. Convoy was available at a variety of 2014 events, including on May 3 at a "Kids Walk" event at Fuji Speedway, in special packaging on May 16 at the "Transformers Celebration 2014" midnight event at the Sunshine City Toys"R"Us store in Ikebukuro, on June 15 at Tokyo Toy Show 2014, at the Aeon Mall in Kasukabe on July 19, and at the "Transformers Expo" event in Yokohama on August 9. Convoy was also available as one of three preorder bonuses for Cloud Roadbuster.
