Optimus suffers from a design flaw that many other Voyager Class figures in the Combiner Wars line experience: the detents, or "click points", on the heavily-ratcheted outward motion of his hips (which also form the hips of his torso mode) are few in number and very far apart. As a result, Prime's legs have great difficulty assuming the natural "A-stance" formation that the angled design of his foot sculpt seems to have been meant to accommodate. Likewise, when forming the torso of Ultra Prime, the interactions of the knee-lock mechanism and the hip detents almost always force Ultra Prime's legs into either an awkwardly knock-kneed arrangement or an equally awkward, and often unstable, bow-legged posture (as seen in the image to the right) that prevents Ultra Prime from standing flat-footed. Unlike Motormaster, this version of Optimus was the only one to not receive the improved hip ratchets implemented in its future releases in some shape or form by Hasbro, though they would be used for the Battle Core redeco later in the line. However, there are third party ratchet replacements for the hips.
This Optimus Prime is a minor redeco of the One-Step Changer figure, omitting the paint apps on the knees, the flames on his shoulders, and changing the robot mode chest's deco. Along with his wavemate Bumblebee, Optimus Prime loses his pin on his leg, which is used to activate Stomp & Chomp Grimlock's pop-out weapons and gimmicks. As with the first wave of the Turbo Changers, Optimus features a nearly invisible tampograph on his vehicle front, which can be revealed with Mega Turbo Changer Dragonstorm's UV-powered Cyberfire gimmick.
This mold was redecoed in 2000 as Car Robots Black Convoy, and slightly retooled as his US incarnation "Scourge". After Scourge, the next use of this mold was planned to be Toxitron, which ended up being canceled. The slightly retooled version of this mold was released in 2006 in Japan as reissue Battle Convoy, which was the name of this toy during the Japanese Generation 2. The reissue used the Robots in Disguise modified tooling, with a slightly modified deco using silver vacuum-metalized plastic on his chest and trailer sides along with additional paint applications and G2 symbols. The mold was also redecoed to create a new Generation 2 version of Ultra Magnus as an E-Hobby exclusive (unusual in that the character was killed in the course of Japan's Generation One fiction).
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.

This set is a ToysЯUs Japan exclusive, consisting of Powerlinx Optimus Prime (dubbed "Convoy Final Battle Coloration" and redecoed with more show-accurate colours, principally a silver mouthplate instead of red and varying color saturation from the Hasbro version), a "crystal" version of Overload ("Ultra Magnus Special Clear Version") made out of transluscent plastics, and an exclusive X-Dimension redeco of the Street Action Mini-Con Team. This set is entirely "new" content not available in the normal mass-retail Micron Legend line, and is also the last release of "X-Dimension" Mini-Cons. Rather than come with individual bio cards for the various characters, the set came with only a single card for Magna Convoy.
A larger version of Prime, with Advanced Automorph technology and a more complex transformation procedure. Has two sets of electronic sounds and lights that activate when the head pops up or when you press a button on the roof (in truck mode), and a single projectile weapon that can swing over the toy's right hand. Unlike Megatron (whose head is fixed) and Brawl (whose head is connected with a ball joint), Prime's head is limited to side movement due to the circuitry on his LED eyes. This figure has a folding cannon and a firing missile.[76] With this figure standing nine inches tall and Optimus being 28 feet (336 inches) tall, the toy is about 1/37 scale.
Leader class figure, this is his form used in the Cybertron television series. Can combine with Leobreaker (or Nemesis Breaker) and/or Cybertron Wing Saber, and can use Metroplex's axe or Vector Prime's sword. At first, Optimus Prime's (Galaxy Convoy in the Japanese version) alt-mode is a futuristic firetruck, although some believe it to be some sort of mobile weapons platform (the show itself treats it as a firetruck). This can also transform into a wing mode, with wings and cannons on each side of the truck. In addition to his standard robot mode, he can combine with his rear 'trailer' section to form a heavily armed super mode. That trailer section can also form an independent weapons platform, usable by anyone. His face, designed in the classic Prime style, merges the two mouth-plate elements - a slitted version to expose his mouth, like Beast Wars Optimus Primal did on the television series and a full mouth-plate which can rise to cover it.[60]

Part of the first wave of Bot Shots Series 2 launchers, this new-mold Optimus Prime transforms into a very boxy Generation 1-styled truck with trailer. As a Spin Shot, one manually winds up his upper body beforehand when transforming him into vehicle mode, where striking the front of the vehicle will cause him to burst open and spin while auto-transforming. He comes with a launcher used to propel him to great speeds, as well as four cube targets for him to knock over.
Part of the new Adventure Shokugan series, this Optimus Prime is a transformable snap-fit kit molded in red, blue, and yellow plastic with detailing from stickers. The kit's transformation engineering is borrowed from the Warrior class figure. But unlike the said toy, the Axe must be pegged onto Prime's legs before transforming, and his shoulders are molded on his front truck halves/shoulders not being flipped down. Also, the stickers are used to cover the molded cavity on the front shoulders. As with Fixit & Underbite, Optimus Prime is fully transformable.
In 2007, following the release of the Matrix's energy, Prime began to suffer from visions which foretold a great transformation for Cybertron. Events began with the Decepticons' theft of the key to the Plasma Energy Chamber, which forced Prime to consult Alpha Trion within Vector Sigma. Prime learned that the mega-computer had orchestrated events in order to restore Cybertron's Golden Age. When the Plasma Energy Chamber was opened and threatened to drive Earth's Sun supernova, Spike Witwicky and the Nebulans, who had become involved in the conflict as a result of these events, were able to drain off the excess solar energy and revitalize Cybertron. With the Decepticons driven off Cybertron and Nebulon free from tyranny, Cybertron enters into a Golden Age of peace and prosperity under the leadership of Optimus Prime and the Autobots.

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 G.I. Joe line of toys has always been the definition of "action figures," featuring moving joints, changeable outfits and ripped man-bodies underneath. If this all sounds a bit gay on paper than it should be noted that G.I. Joe figures are all armed with a vast array of weaponry. Also, if you ever suggest that Snake Eyes might be gay, make no mistake, you will be dead before you even see the movement in the darkness.
The Autobots and the Decepticons came to a distant world in the grip of an ice age. Assuming alternate modes based upon the dominant (though doomed) indigenous creatures of this planet, they continued their ancient, unending war. However, the Autobots, with their energy levels dangerously low, withdrew from combat as the world grew colder. They sought refuge in a deep cavern and entered stasis lock, awaiting the day when surface conditions changed to better suit their operation. Hearts of Steel #1 Optimus lay under the Mare Rurek Glacier. Infestation 2: The Transformers #1 Millions of years later, Bumblebee was awoken by the hammering of humans working on a rail line. He briefly considered awakening Optimus Prime, but thought better of it. After discovering the world had changed significantly, Ratchet thought there was no reason to awaken Prime. Hearts of Steel #1 When Bumblebee discovered the Decepticons were once again active on this world, Ratchet and Prowl agreed that the Autobots must intervene, but again decided out of rousing Optimus from his slumber. Hearts of Steel #2

After a period of effective leadership, which saw the activation of several new Transformers including the Aerialbots, who Prime infused with life using the Matrix, Prime engaged Megatron in a video game duel for possession of a super fuel. Prime was victorious, but Megatron implemented a cheat code that killed Prime later. Autobot surgeon Ratchet's subsequent efforts to restore him were unsuccessful, and his body was launched into space. The Autobots were unaware of the presence of the physical Matrix within the corpse. The funeral barge eventually crashed on a giant moon and, as it lay there for an untold time, the Matrix reached out to nearby living organisms, studying and recreating them.

In his first appearance in the series, Optimus looks similar to the original G1 Optimus Prime until he copies himself with a semi-truck and his design in robot mode changes to the image shown here. Soon after, he retrieves his Mini-Con partner, Sparkplug. The cab of his truck mode detaches to form Optimus himself, while the trailer transforms into a battle station mode operable by Optimus and several Mini-Cons. Optimus can also combine with his base to form a "Super Mode" robot that, when combined with Sparkplug, can fire a series of powerful lasers. Additionally, Optimus can combine with Jetfire and/or Overload in his Super Mode for additional power.[49]
Being a brand new and intricate remake of the Autobot leader, MP-10 was used as the gold standard in terms of scale for future Masterpiece figures, with all the upcoming releases being sized to best match him. Much like his older incarnation, he was also cherished by collectors, generating heated debates on which version is the best one up to this day.[5]
Another version of Prime was also available in the second wave of the Smallest Transforming Transformers series as a chase figure. This almost entirely white version of the figure is clearly based on the version of the original Prime cab robot used in the Generation 1 Ultra Magnus figure, but was nonetheless sold as Optimus Prime for the Smallest line.

Optimus foiled Megatron's attack on 21st century Tokyo after informing his old foe that wherever he would pop up, the Autobots would be there to thwart his evil intentions. Henkei! Henkei! volume 1 Optimus and Bumblebee later intervened when Astrotrain attacked Shinjuku Station, using their bodies to shield nearby humans from the destruction the triple-changer brought about. They were unaware that Astrotrain's rampage was really a distraction staged to keep their attention away from Megatron's gathering of energon cubes nearby. Henkei! Henkei! volume 2 Optimus continued to do battle against Astrotrain until Rodimus showed up to provide the Autobots with additional firepower. Henkei! Henkei! volume 3
The Transformers Animated series was broadcast internationally in 2008 except in Japan, where it aired in 2010. This new series uses a very different art-style from the previous series. The Autobots and Decepticons, while fighting in space for possession of the Allspark, crash-landed onto a futuristic Earth and resume their battle after laying dormant for years. In addition to the Decepticons, the Autobots have to face the human villains as well. Classic characters such as Optimus Prime, Bumblebee, Prowl, Starscream, Megatron, Jazz and Ultra Magnus appear in this series.
Alternators Optimus Prime transforms into an accurate, fully-licensed 1:24th scale Dodge Ram SRT-10. The vehicle mode features rubber tires, functional steering, opening hood, tail gate and doors with a detailed cabin interior. His robot mode body sculpt details are based upon the 20th Anniversary Optimus Prime toy. However, his headsculpt is based upon Powermaster Optimus Prime. He is armed with a small pistol that is formed from his engine.

Based on Optimus Prime's Cybertronian form as seen in the Dreamwave comic book "The War Within", this version of Prime transforms into Cybertronian truck. The figure was personally designed by comic artist Don Figueroa, who created the original comic design in the first place, and his signature is left on the figure in the most literal way: the word "DON" can be seen sculpted into the barrel of his silver ion blaster.
(As an odd postscript to this tale of footwear-induced madness, although the promo pictures all showed the shoeformer as a white and navy blue sneaker that transforms into a white and aqua blue robot, the product actually released sported much darker colors for all the robot-mode parts, with a deep teal instead of aqua, and almost all the white replaced by an icky tan/cream/grey color, including the head. Basically, the figure looks like the promo picture viewed through really dark sunglasses. Although this certainly doesn't make it look any more like Prime, you might argue that it looks a little less like Magnus. Sorta. Maybe. Not really.)
Forming a roughly 11-inch figure when fully assembled, Diablock Convoy is highly articulated, save for his head, which is only able to move up and down. Said head is also by far the most stylised aspect of the figure, with no real attempt to approximate Prime's face or mouthplate, instead featuring only a reversed block that gives the odd impression of a cycloptic eye. It is possibly intended to actually represent his forehead grill, as a yellow block inside his head construction remains barely-visible through a slit in his face, possibly intended to represent the classic toy's yellow eyes.

Prime's trailer opens up into his Combat Deck, containing the scout drone, Roller. The interior of the Combat Deck features three pegs that can accommodate Prime's laser rifle, fuel pump and nozzle accessories, and seating for two Diaclone drivers. As its central feature, the Combat Deck features a missile-armed repair drone pod mounted upon a boom lift arm (featuring another cockpit for a Diaclone driver), which can also be extended through holes in the trailer's roof and front-end when it is closed. Situated in the base of the boom arm is a spring-loaded launcher that can launch Roller out of the Combat Deck and into action. Roller himself has seating for four Diaclone passengers, and features a port that can accommodate either Prime's rifle or the fuel pump. The interior space of the trailer allows storage room for one standard Autobot car, which can also be shot forward by the launcher.
