Smash & Change Optimus Prime is a simple figure that transforms by "smashing" the rear end of the truck/the robot's feet into the ground. He features only elbow articulation in robot mode, and includes a sword accessory that can be held in his hand or mounted on the side of his truck mode. The handle on the rear of his truck mode is molded to emulate his Vector Shield.
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.
Optimus Prime returns in Transformers: Revenge of the Fallen. He leads the Autobots as part of NEST in hunting down the remaining Decepticons on Earth. He later engages in a battle with Starscream, Grindor, and a resurrected Megatron. Although Optimus manages to injure Starscream and kill Grindor, he is eventually impaled and killed by Megatron. However, Optimus is resurrected during the battle in Egypt by Sam using the Matrix of Leadership. He is then fused with the dead body of Jetfire, giving him an extremely powerful upgraded mode. After severely maiming Megatron, he kills The Fallen, forcing Megatron and Starscream to retreat. At the end of the film, Optimus thanks Sam for reviving him and again transmits a message to space, hoping to find more Autobots.
Part of the third wave of 2012-onwards Generations Legends Class toys, Thrilling 30 Optimus Prime is a new mold that is roughly the same size as a Cyberverse Commander Class toy. Both his truck and robot mode are based on his Don Figueroa-designed body from IDW's ongoing series, and features 5mm-compatible hands and roof. He comes with an Ion Blaster which has both 5mm and 3mm posts.
Prime would make one further surprise appearance in Dreamwave's Transformers: Armada comic series, although it would not be the Prime of Dreamwave's first series. When the Optimus Prime of the Armada universe disappeared, pulled into another dimension by the power of Unicron, the Chaos-Bringer sent something back in his stead: a nearly dead Optimus Prime from that universe, who warned the transformers of Unicron's coming into their universe before dying.
The third version  would quite possibly have been the most gimmick loaded Transformer in the history of the line, simultaneously being a Powermaster, Headmaster, and triple changer. The Headmaster also would have been a triplechanger, turning into a sort of armored four-wheeled rover (Roller II?) and robot as well as a rather silly looking Optimus Prime head with four vertically aligned wheels jutting off the sides. It seems that when the extra Headmaster gimmick was scrapped, the super mode head remained separate rather than being reintegrated into the trailer hitch such as on the earliest design. Notably, the body of this design is extremely close to the final design.
Naturally, Optimus Prime got the biggest of the sets in the first year of Kre-O. The set can be built into a large long-nose tractor-trailer rig with a removable "sleeper" cab that hides a computer station, and a trailer that can carry the set's two motorcycles or open up to carry larger car builds. The robot mode build includes a huge Optimus, based largely on the live-action movie Optimus, though with a head based almost directly on the Classics Voyager Optimus. He is armed with a distressingly plain brick that fires pressure-launched missiles (aka his smokestacks). Most of the leftover parts in robot mode become a "headquarters" which is mostly just a random assemblage of mismatched-color panels and a pair of barricades. Both main builds leave numerous parts unused if you go expressly by the instructions, but hey, it's a building kit, surely you can find someplace to apply most of them.
Nonetheless, I remain a big fan of Lego and although I think they have somewhat moved away from their roots with the excess of licensed products (and the earlier licensed products were, in my opinion, not very good because they contained too many specialized non-generic pieces that weren’t useful for generic building. But that situation is improved and in particular we have found the Star Wars sets to be of most value for generic building, because they generally have very few really specialized pieces (although to be fair the sets are most useful for building other spaceships, etc).
The 1984 and 1985 toy lines contained several figures of note. Megatron, the Decepticon leader, originally transformed into a realistic Walther P38 pistol with stock and barrel extensions and scope. The Megatron toy was delayed till 1985 for release in the UK. The Constructicons were the first "gestalt" team in the Transformers line, but were different from most subsequent gestalt teams in that they consisted of six members instead of five. The Autobot Jetfire was repainted from a Macross toy, specifically the VF-1 Valkyrie, and the character was renamed Skyfire in the animated television series program for copyright reasons.
Another Hasbro release of the MP-10 mold, which is basically a reissue of the 2010 Transformers line's Masterpiece Optimus Prime, but with the Japanese release's ID Number. Surprisingly he is NOT mistransformed on the initial official photography... until secondary stock photos had the vehicle mode slightly mistransformed. Unlike the original, Hasbro version, this version features silver paint on the interior of the trailer. This version also removes the red paint on the die cast hinge piece in his body and replaces it with blue paint. Sadly, this figure doesn't come with the Key to Vector Sigma. Due to compact packaging, the trailer is prone to scuffing.
Optimus Prime appears in the prequel novel Transformers: Ghosts of Yesterday, where he and a group of Autobots travel in the Ark searching for the Allspark, battling Starscream's Decepticons along the way. While going through a worm hole, the Autobots find themselves encountering a group of humans in a spacecraft reverse-engineered from studying Megatron. With this discovery, Prime realizes the significance of Earth, as both Megatron and the Allspark are there. After saving Bumblebee from a pit of rock-chewing cave worms, Prime battles Starscream. He is about to be gunned down by Starscream and Bonecrusher when he is saved by the human craft. In retaliation, Starscream obliterates it.
Labeled as a "Triple Changer", Striker Optimus is a redeco and retool of Dark of the Moon Supreme Class Jetwing Optimus Prime, with new weapons. The base figure has most of the same mold changes as Jetwing Optimus Prime (see below), but has been altered further; in particular, the transforming smokestacks and fuel tanks/ion blaster parts have been replaced with retooled regular tanks that now function as mounts for the new accessories. The colors on the toy are darker than Jetwing Optimus, with a different flame deco that extends farther along the sides of the toy. Additionally, two new 5mm holes have been added to the gray hinge behind the cab in order to accommodate the Toys R Us Japan-exclusive battle blade accessories. The "I am Optimus Prime" saying of Buster Optimus Prime has also been replaced with the "We must stop the Decepticons!" saying of 2010 Transformers Optimus Prime, although batteries are not included.
Entertainment Pack Optimus Prime is a slight redeco of the SDCC figure, with some deco differences between the SDCC release; this version has gray windows instead of blue and is missing some of the silver deco on the helmet and roof/feet, as well as the yellow paint on his lights. His midriff is also darker. Optimus also comes with a similarly-scaled Megatron and PVC figurines of Jack Darby, Miko Nakadai, and Raf Esquivel.
Hero Optimus Prime was the first new-mold Optimus Prime toy in the Generation 2 line. He transforms into a Kenworth truck of unknown model with a flatbed trailer. The truck and trailer form his robot mode, but cannot disconnect. His primary gimmick is an air-powered missile launcher that uses an air bellows attached by hose to launch his large, hollow, soft-rubber-tipped missiles. The bellows and missiles attach to his back in robot mode. His rifle plugs into the launcher's main body in truck mode.
Although the original Japanese incarnation of Transformers: Cybertron, known as Transformers: Galaxy Force, was produced apart from Armada and Energon, the series, as originally conceived by Hasbro, was as the third part of the trilogy. The English language dub of the series treats it as such. Consequently, inconsistencies arise between Cybertron and the other two series, but have been explained by the Cybertron comic book, available exclusively through the Official Transformers Collectors Club, as the result of fluctuations in the fabric of reality caused by the Unicron-induced black hole.
Hot Rod appears in All Hail Megatron , while traveling through space by himself, he found himself under attack by the Torment, a Decepticon warship crewed by Bludgeon and the Pretender Monsters. He was shot down, but managed to transmit a distress call to the Autobot starship Trion, which came to his rescue. After the Decepticons were chased off, Hot Rod joined the crew of the Trion. When the Decepticons' galaxy-wide assault hit, the Trion was shot down over Cybertron. Hot Rod sent out a distress signal and was ecstatic when he ran into some other Autobots. Hot Rod was taken back to base and relayed the story of how he and his other crew-mates from the Trion arrived on Cybertron, having been diverted there by Decepticon ships and forced to crash land. Once on the surface, Hot Rod sent out his distress signal and was so sure someone heard it. Kup arrived with the rest of the Trion's crew at that point, just in time to tell Hot Rod of course no one heard his message. After the Autobots narrowly avoided the Insecticon swarm and Sunstreaker sacrificed himself, Hot Rod jumped to Drift's defense when he was being insulted by Bumblebee. When the Autobots were later rescued by Omega Supreme, Hot Rod was glad that he sent out the distress call. He was then ferried to Earth with the other Autobots aboard Omega.
A gold chrome remold of the 2007 movie Leader Class figure by Hasbro Hong Kong. Limited to 88 units, with only 10 released to the public at the 2008 Animation and Comic Show convention; all of which were sold only to the first 10 people to spend more than HK$3,000 at the Hasbro booth. Because the figure is permanently fixed to the trophy base, it is no longer transformable.
An extremely simplified version of Optimus Prime, this McDonald's Happy Meal toy transforms into a trailer-less truck cab. He is formed out of a large percentage of translucent plastic, and can combine with the other Happy Meal Armada toys (Hot Shot, Red Alert, and Smokescreen) into a human (well, robot) pyramid-style configuration, notionally considered a "Mighty Robot".
Available exclusively from Japanese clothing company A Bathing Ape in 2017, MP Convoy Reissue BAPE Ver. is a trailer-less redeco of the MP-10 mold sporting a unique black color scheme matching the Convoy Reissue BAPE Ver. BLACK of the original G1 toy, with "BAPE's famous camouflage pattern" and an ape head print on the shoulder replacing the usual faction symbol.
In true Prime style, forward portion of the vehicle mode detaches to become Prime himself, while the rear "trailer" transforms into a gun emplacement. In robot mode, the barrel of the truck's left cannon detaches to become a hand-held rifle for Prime, and the figure features an opening chest compartment concealing a removable Matrix of Leadership accessory. Prime's gigantic hands mean that he can't hold it especially neatly, but he can certainly grip hold of it. Atypical of both most Unicron Trilogy figures and indeed, Optimus Primes in general, Prime's hands are not designed to accommodate weapons with 5mm posts, instead featuring a small peg-hole in his palm that allows him to tightly grip objects designed to fit there, like his own rifle, Leobreaker's whip, Cybertron Wing Saber's swords, and Cybertron Metroplex's axe. However Cybertron Wing Saber's sword hilts will also act as adaptors allowing Prime to hold and use 5mm weapons.
He now comes with a half-translucent gun which lights up and expands MechTech-style when the lever is pulled. Bizarrely, the main section of the weapon is sculpted to resemble Prime's forearm, with the unfolding part being his in-show gun. Additionally, he comes with an opaque sword resembling the Star Saber, which he can wield two-handed. The gun features a peg on its underside and a port on each side, while the sword features a peg and peg-hole on its hilt in addition to its 5mm handle. In robot mode, either accessory can mount on his hands, on either of his shoulders, or be pegged into either of his half-translucent forearms. In vehicle mode, the top of the vehicle mode cab can also fold back to reveal two additional peg holes, and there are three peg holes (including the fifth wheel hitch) on the back section, although the hitch tends to open up and not hold very well.
In Transformers Ongoing, which takes place two years after the events of All Hail Megatron, the Autobots would remain on Earth as Prime feared the return of the Decepticons. Unfortunately, this led to the capture of a number of Autobots by Skywatch, including Windcharger, Gears and Prowl. Hot Rod was reformatted into a Pagani Zonda. Already frustrated, he lashed out at Optimus, accusing him of keeping the Autobots on the planet because he needed someone to protect and demanding he be allowed lead a team to rescue Prowl. An admonished Prime agreed to a covert operation, but with Ironhide along to watch over things. While Prowl was freed, it turned out the humans had used him as bait to draw the other Autobots in. However Wheeljack's new shielding protected Hot Rod's team from Skywatch's inhibitors and in a panic the soldiers switched to lethal measures. Hot Rod was targeted and Ironhide was killed protecting him. An enraged Hot Rod turned on the humans, damaging their equipment and machinery.
