When the legendary Energon Cube was lost to the reaches of space, Optimus Prime led a small team of Autobots in pursuit of it. The giant energy source crashed on Earth in the Japanese town of Hoshinochō, where it shattered into fragments that were scattered far and wide. Prime and the other Autobots set up a subterranean base below the Cube's impact crater and began their search for the shards, taking the forms of local vehicles to hide their activities. Despite their attempts at remaining unseen, glimpses of the Autobots only magnified the reputation the crash of the Cube (believed by humans to be a meteor) had given Hoshinochō: that of a hotbed of rumored alien and UFO activity, Japan's answer to America's Roswell.

The seldom seen 5th season re-airing of the show featured the G1 episodes retold by a stop-motion Powermaster Optimus Prime to the live-action youngster Tommy Kennedy. Although no back story was ever provided for how Prime became a Powermaster, the new sequences are said to take place after the four previous seasons. This indicates that Prime became a Powermaster in the original Sunbow continuity.
Although peacetime in the decade that followed the apparent deaths of Unicron and Galvatron afforded Prime the opportunity to train his own elite squadron of Autobots the martial art of Kumite. The re-emergence of the war, however, forced him to return to his role as commander. The conflict for control of the Mini-Cons and the truths he was forced to face in his confrontation with Unicron seems to have changed him. Optimus Prime, Grand Convoy' in the Japanese version, was now a stern, more direct commander and shows little of the conflict that held him back before. Despite this, he is still known to make the same kind of decisions, which include an emphasis on team work and the foundation of the Autobot values.

The instruction manual for the MP-04S Convoy Sleep Version reveals a hidden message saying that Rodimus will be the next installment in the Masterpiece series. Concept sketches of the figure were released online in July 2010. The figure is a faithful modern recreation of the original G1 toy. Gimmicks include retractable binoculars, spinning saw blade and the Matrix of Leadership, but the figure's main feature is the ability to transform into both Hot Rod and Rodimus Prime. The transition between the two incarnations involves rotating the face, extending the legs and adjusting the spoiler on the back.
A golden-chrome redeco of Cybertron Metroplex was offered as a contest prize in the December 2005 issue of TV Magazine, and came with an equally blinged-out Legends/EZ Collection Optimus Prime figure. Fifteen of this set were available as prizes in the initial contest; a single Metroplex was later offered as one of many prizes in a Takara website contest, but this version came only with the standard metallic paint version of Prime.

In Another Light, Rodimus finally assumes total control over the Autobots upon Optimus Prime and several of his closest loyalists being jettisoned into space and left near death following the Battle of Decepticon City. However, his reign came to a swift end when the group returned, having been reformatted into the Knights of Unicron. The heroically reborn Optimus, now known as Nova Prime, engaged his usurper in battle and defeated Rodimus, sending him plummeting into Cybertron's depths. However, Rodimus then encountered the malevolent Primus, who enlisted his aid and that of other "true Autobots" in ridding his surface of those he considered vermin-namely, all Decepticons and Autobots not loyal to the same cause. This would lead to an epic battle between Primus' minions and the heroic Transformers of their universe: Galvatron's Decepticons, Nova Prime's Autobots, and a group of Maximals created from Classics Autobots.


The "Unicron Trilogy" version of Optimus Prime is a fictional character of this branch of Transformers lore. Appearing in Transformers: Armada, Transformers: Energon and Transformers: Cybertron (known as the aforementioned trilogy), Optimus is the leader of the heroic Autobots. He often converted to his super combat mode. In all three series, Optimus' English voice actor is Gary Chalk, who previously voiced Optimus Primal in Beast Wars and Beast Machines.

Really great, well-researched article. I think you hit the nail on the head here – the fact that there are more expensive sets than ever before affects perception. Also, I’m pretty sure the presence of a baseplate (light but large) in the old sets made them seem bigger. I don’t like the lack of baseplates in new sets – it does make them seem smaller.

After having spent an extended period of time lost on Quintessa, Optimus was returned to Cybertron by the Turbomasters during their efforts to retrieve the similarly lost Flash, who he had been drawn into Perceptor's Dimensional Interface Assembly. The Age of Wrath Pt.5 Though badly damaged, Optimus led an insurrection against the then Megatron-controlled Cybertron, and successfully overthrew his enemy from power, all the while thwarting a Quintesson invasion. The Age of Wrath Pt.6
Epic Optimus Prime is a 22 inches tall, non-transforming Optimus Prime figure, featuring limited articulation in the waist, shoulders and wrists. His chest can be opened to reveal a command center with a seat and room to display at least three figures. His arms also feature one seat each to accommodate more figurines. The back of his arms and legs are hollow with "shelves" that allow even more figurines to be displayed.
A gold-chromed version of the Voyager Optimus Prime toy was available as part of the same Lucky Draw contest as the Golden Protoform Optimus (see above) in the December 2007 issue of TV Magazine. Limited to only 3 pieces, it is insanely rare. The photographed sample here features a chromed truck grill, while a boxed unit has an unchromed grey grill; the owners of both pieces, the Mapes Brothers of Transformers @ The Moon, believe both are genuine TakaraTomy toys, so it unsure if the one with the chromed grill is a testshot or a production variant.
(translated from the Japanese Wikipedia article) The Transformers: Kiss Players was a Japan-only line of Transformers toys, manga, and audio dramas released in 2006. Kiss Players is set in an alternate Transformers universe where the Transformers are powered by the kisses of young girls. The toys themselves come packaged with small, scale figurines of the girls who power them. The toyline was openly admitted to be aimed at a specific part of the market — adults, rather than children. The comic that accompanied the Kiss Players was an unashamed reflection of this, with several images which were considered by some to be very sexually themed.

In Transformers: Armada and Transformers: Energon, Optimus Prime shares the role of main protagonist with Rad, Alexis, Carlos, Starscream and Hot Shot. The Optimus of this universe shares many similarities with his parallel universe versions, including nobility of spirit and a strong desire to protect all humans on Earth. In this continuity, the two sides are not looking for energon, but a small race of power-enhancing Transformers known as Mini-Cons. Optimus led his small band of Autobots to stop Megatron from acquiring their power for himself.
Prime suffered a severe, though unfair, defeat when Megatron challenged him to one-on-one combat while imbued with the different abilities of all the Decepticons. Teletraan I, the Ark's computer, discovered the deception in time, and the Autobots were able to drive off the Decepticons. In "Prime Problem", Megatron created a clone of Optimus, which caused confusion with the other Autobots. Windcharger and Spike, however, were able to identify the clone before it led the Autobots into their demise.
Optimus Prime was one of only two Armada-theme figures in the otherwise Generation 1-centric Q-Robo Collection line of super deformed PVC figurines, the other being Armada Megatron. Like all the figures in the series, Prime featured articulation in the neck and shoulders, and was also available in a translucent colored plastic: as an Autobot, Optimus came in translucent red, but was also uniquely available in a golden metallic "pewter" variant as the wave's solitary rare chase figure. All Q-Robo figures were sold in sets of two, one full-color figure and one translucent one, blindpacked in a plastic capsule.

As one of the first Transform Jr toys, this version of Optimus Prime was released under the early name for the series, Transform Gōkin. As a smaller, simplified version of the original Generation 1 Prime figure intended as a low-cost alternative for younger children, Prime features a similar transformation, with a removable head in addition to fists, but lacks rubber tires and translucent windows. As with most other Transform Jr figures, he lacked any of his major accessories, coming only with his rifle and a cardboard replacement for his trailer that had to be assembled by the buyer.
Marketed as a reissue of Powermaster Optimus Prime, this Toys R Us-exclusive Commemorative Series figure is in truth based on the Ginrai tooling on the toy that had previously been exclusive to Japan. It features a die-cast metal cab with translucent blue windows, and shortened, chrome smokestacks, and comes packaged with the drone Apex Bomber (formerly Ginrai's partner Godbomber), who splits into several components and combines with Prime to form "Apex Armor". As with all other Commemorative Series figures, Prime's new spring-loaded missile launcher featured an elongated missile.

Came with the Mini-Con Sparkplug. Could combine with Armada Jetfire (and its repaints) and/or Armada Overload (and its repaints). The trailer could convert into a base for Mini-Cons. In Japan a gold chrome edition of this toy was released as a Lucky Draw special. With its trailer the vehicle mode of this toy bears a great resemblance to G1 Star Convoy. According to the Armada video game Armada Optimus Prime is supposed to be 22 feet 10 inches tall (696 cm tall) and the toy is 17.5 cm tall. So that's a scale of 1:40.[55]
During the period between December 26 2010 and January 31 2011, Hasbro ran their "Supercharge Your Holidays" promotion: for every $20 spent on Hasbro-branded product, customers could receive a free, random product from a list provided by Hasbro. Among the items on the list was "Transformers Activator & Speed Stars Mini Vehicle". According to this discussion thread on Allspark.com, Rally Rumble Optimus Prime (as the figure is listed in the thread) was one of the figures distributed.
While the Transformers animated series came to an end in America in 1987 after The Rebirth, production was continued in Japan with three new, exclusive animated series spin-offs to continue the story. The first of these series, Transformers: The Headmasters, supplanted the events of The Rebirth, picking up one year after the events that saw Optimus Prime's return to life.
Released as part of The blindpacked EZ Collection Real by TakaraTomy's "TakaraTomy A.R.T.S", this Optimus Prime is an extensive redeco of the Revenge of the Fallen Legends Class figure, sharing the same paint mask with the Battle Damaged figure sans the weathering. Like all land-based vehicles in this line, He also features an extra paint applications on the wheels rims. This redeco also uses the slightly small fuel tank/elbow tabs.

Legion Class Optimus Prime is a redeco/retool of the first Revenge of the Fallen Legends Class figure, with the deco resembling the paint job from Optimus Prime's Western Star "5700 OP" concept truck. While the main body is identical to the figure, the arms and legs are newly tooled, with simple assemblies for the wheels. The retooled legs now features a more solid stopping point, which prevents the center front grill/legs to swing back further. It should be noted that his flame decals are painted over the side windows.
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.
The largest Movie Optimus Prime toy (until Revenge of the Fallen, that is), Leader Class Optimus Prime features the most accurate representation yet of the CGI designs' complex transformation sequence, the only difference being the arms which are placed behind the cab while they constitute the hood in the CGI model. He transforms into a heavily-customized Peterbilt 379 conventional extended-hood, and unusually for a mainline figure, he has rubber tires on all his wheels. His Ion Blaster weapon is stored in the rear of the truck's bunk, exposed like an engine block. Though Optimus has no trailer, he has a hole where the fifth wheel (known among fans as a 'hitch') is sculpted in the rear of the truck, should owners find a suitable trailer to use. Due to safety reasons, the tips of his long smokestacks are made of rubber. A switch on top of the cab roof activates horn sounds and window lights.

In one possible scenario, Optimus was surprised to see Beachcomber return to Autobot headquarters soon after his departure. Beachcomber informed Optimus that he had uncovered the Decepticon's newest hidden fortress, and he suspected that the Decepticons were up to something big. Optimus sent out Beachcomber once more, this time along with Powerglide and Windcharger to investigate the Decepticons' plot further.
Optimus Prime and his troops lay deactivated on the Fera Islands for three million years until G.I. Joe stumbled upon them one day in 1939. The Line The Autobots were reactivated by a repair drone and given new disguises, with Optimus Prime being reformatted into an unknown World War II-era human vehicle. He explained to Duke who they were, and learned that Megatron's Decepticons had been reactivated a year prior, and were currently wreaking havoc on Europe along with Cobra. While hesitant at first, Optimus Prime soon joined G.I. Joe in their mission to destroy Cobra and the Decepticons. Transformed After commanding the Aerialbots to get the Seekers out of the way, Prime advanced across the Fera Islands, but met resistance in the form of Rumble. Trial by Fire
If Optimus went along with Perceptor’s plan, he sent out Sparkplug to fetch the Autobots’ secret stash of emergency fuel. Putting all of his faith in the Autobot scientist to uncover a cure swiftly, Optimus attempted to comfort his troops as they all began to experience sickness pains. Then, Red Alert informed Optimus of a Decepticon attack force moving in on their position, prompting Optimus to ask Perceptor to dispense whatever cure he had been able to concoct, despite it being untested. Perceptor suggested another course of action to Optimus; the tainted fuel the Autobots had left untouched could be used to create a poisonous smog if lit aflame. The Autobots could attempt to poison the Decepticons with their own concoction, or they could risk the untested antidote, despite whatever side-effects it may have.
Optimus Prime's Japanese name is "Convoy", which is named after his original name "Battle Convoy" in the Diaclone toyline, because the name "Optimus Prime" is difficult for Japanese kids to remember and pronounce.[2] All Optimus-inspired characters were called variations of Convoy in Japan up until the 2007 Transformers film, at which point TakaraTomy changed their minds and began using the name Optimus Prime as well. Presumably to avoid confusion, this change includes the Generation 1 version of the character as well, who is now called Optimus Prime in newer products and fiction such as Transformers United and Transformers: All Spark, though his name remains Convoy in material aimed at adult collectors such as Alternity and Masterpiece.

After the film, in season three, Rodimus did not have time to rest on his laurels as commander, immediately finding himself and the Autobots targeted by the Quintessons, who lured him to their planet of Quintessa and detonated it in hopes of destroying the Matrix. Rodimus and the Autobots survived, however, and Rodimus proceeded to voluntarily short-circuit himself to allow his life-force to enter the Matrix, feeling that the answer to the mystery of the Quintessons' identity lay within it. His hunch proved correct – the Quintessons, he discovered, were the Transformers' creators, and Rodimus knew that the future would be a difficult time for the Autobots.
Unusually for the smaller Voyager Class of toys, Robo-Vision Optimus Prime comes packed in robot mode in a special hexagonal column box with many windows, similar to the original packaging for 20th Anniversary Optimus Prime. The package also includes a Robo-Vision Decoder. Strangely, this Target exclusive preceded the release of the regular Voyager by a large margin, coming out on June 2, 2007 with the initial wave of movie toys.

The SS-03 version of Takara's Deluxe-class Optimus figure, based on the Anniversary release, was released in Hasbro markets in a two pack with the smaller Japanese Megatron figure. There are some tiny but notable differences between this and the Anniversary figure; the Hasbro version uses a more neutral dark-gray for the main body as opposed to the Takara version's blue-tinted dark-gray, plain dark-blue plastic rather than dark-blue-with-sparkles, and plain yellow paint for the cab's lights rather than sparkly-yellow/gold.
Based on the Classics toy line, the Timelines 2007 story is set 15 years after the end of the Marvel Comics story (ignoring all events of the Marvel UK and Generation 2 comics). According to exclusive bio information in the Transformers Collectors' Club magazine #15, Hot Rod followed Optimus Prime back to Cybertron from the Planet Klo. Once back, Hot Rod took up racing, but after a while found it pointless. Optimus Prime assigned to help organize the millions of Cybertronian refugees who returned to their home world. Hot Rod chaired the Cybertron Grand Challenge race, a race which featyred combined Autobot/Decepticon teams. With his maturing Hot Rod changed his name to Rodimus and was chosen to return with Optimus Prime to Earth to stop Megatron. Optimus Prime returned to Earth commanding Bumblebee, Cliffjumper, Grimlock, Jetfire, Mirage and Rodimus. When the Cybertronians Skyfall and Landquake arrive on Earth unexpectedly, Megatron attempts to destroy them, but Optimus Prime and his Autobots are able to drive Megatron away. Rodimus is wounded on a mission with Optimus Prime, before being brought back to the Autobot base.
