In the United States, Canada, and Hasbro's Asian markets, Masterpiece Movie Series Optimus Prime was exclusively available from Toys"R"Us, whereas in Spain, he saw a wider release, being at least available via the Spanish subsidiaries of Amazon and Carrefour. It's currently unknown if he was also available in stores, or limited to online purchases. In Greece, he was officially available via at least one toy store chain, aptly named simply "Toys-Shop", but again might have been available online only.

The toy's primary gimmick is its auto-transforming trailer, which assumes one of three configurations when triggered by an infra-red signal transmitted from the cab robot. Transforming the cab into robot mode will cause the trailer to automatically flip open into a battle station for Mini-Cons, which Prime can stand in the centre of. The base features a central tower with a pop-out artillery emplacement and a mount for Prime's large cannon; a rotating missile-firing turret; two Mini-Con storage bays, one of which featured a manually-activated tab to launch Mini-Cons out; and two live Mini-Con hardpoints, one of which pops up a non-firing turret, the other activating a laser noise.
He next appears in Transformers: Energon, the only time during the Unicorn Trilogy where Prime is not the main protagonist. In Energon, set ten years after Armada, he is no longer able to combine with his trailer. Instead, he has been gifted with the Spark of Combination by Primus, allowing him to combine with the quartet of vehicular drones in his trailer. Fire One, Copter Two, Digger Three, and Submarine Four, can each form either an arm or a leg when they combine with Prime, creating his super mode. Later, Prime gained the ability to combine with fellow Autobots Wing Saber and Omega Supreme, the latter case creating Optimus Supreme.
Released in conjunction with Japanese cellphone maker au[10], au x Transformers INFOBAR Optimus Prime celebrates 15 years since the 2002 au Design Project that resulted in the INFOBAR cellphone, as well as the 10th anniversary of the live-action films. He transforms into a (non-functional) scaled-down replica of the 2002 au INFOBAR, and in lieu of cellphone functions, the figure can be paired via Bluetooth with a smartphone, such as an iPhone, to act as a notification alarm in either robot or INFOBAR mode. The screen is also non-functional, but pre-printed cards are included which can be slid into the screen to show an Autobot logo, Decepticon logo, a mockup of a cellphone home screen, or a technical "Transformers INFOBAR" design. The figure also includes a display stand.
The Universe incarnation of Generation One Optimus Prime is a redeco of the Robots in Disguise Scourge's Spychanger toy, a smaller, simplified version of the original mold. He replaces most of the black plastic with predominantly red and blue, with silver for detailing, with an overall deco making him resemble the original Optimus Prime. Like most Spychangers, he features high speed axles and can roll very well across smooth surfaces, but lacks the weight to propel him quickly.
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.
A five-inch tall, non-transforming highly-articulated PVC figure of Optimus Prime in his Super Mode was the eighth entry in Takara's Mega Super Collection Figure series. In addition to a non-transforming figurine of Sparkplug, Optimus comes with two sets of alternate hands—one set with spread palms, one curled into fists—and is armed with his Convoy Gun, which can either peg into his right fist (and only his right fist) or onto his back.
This new roughly 11-inch leader-sized mold of Optimus Prime transforms from a robot to trailer/truck combination and back, with the transformation taking cues from both the Reveal the Shield Legends Class and the Robots in Disguise Legion Class toys. Surprisingly, he does have a reasonable amount of articulation, including a balljointed head and hinged joints for his arms, shoulders and legs, plus lateral hinges for his feet. His head includes light-piping and, unlike other Cyber Series toys, his truck windows have actual transparent plastic rather than just being merely painted.

In a world where the Transformers' war settled into a series of friendly competitive races known as the Transformers GT, Optimus Prime became the GT Transformer known as GT-R Prime. As a racer he was known for his serious but sometimes hot-blooded personality and his skillful use of the Impact Wrench Gun, though he maintained an honorable policy never to fire directly at an opposing racer's body. Like other racers, GT-R Prime put a limit on his own strength by separating his Matrix into a GT Sister, creating his partner Misaki.
Like several new-mold Revenge of the Fallen toys, Optimus Prime suffers from some cost-cutting measures that affected the final production version of the mold. According to Hasbro's stock photos/back-of-box photo of the hand-painted prototype, the toolboxes on the sides of his legs were designed to fold away further for a sleeker, cleaner look. Additionally, the rear tires would have been able to split in half, with the inner half of the tire going inside the outer half to recreate the thin tires seen on Prime's CG design. Some articulation was lost on the toy between Hasbro stock photography and the final release. His fingers are no longer articulated; instead, the entire hand is now one molded piece. Finally, the lower arms appear to have been originally designed so that his hands could slide in or out of them during transformation. Sadly, he also lacks rubber tires, which the original movie Prime did have. Meanwhile, the articulated fingers was later used for the Asia Premium Series & Movie The Best releases.

In the series released by Marvel Comics, before the Great War broke out on Cybertron, the robot who would be Optimus Prime, before he received the Matrix of Leadership from Sentinel Prime, was a Transformer of note, displaying his skills in the Infraformers Sharpshooting Competition. When the war began, Prime quickly made a name for himself as a combat leader of the Autobots.
(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.
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.
Optimus Prime is the awe-inspiring leader of the Autobot forces. Selfless and endlessly courageous, he is the complete opposite of his mortal enemy Megatron. Originally a mere civilian known as Orion Pax or Optronix, he was chosen by the Matrix of Leadership to command, the first in a number of heavy burdens he has been forced to bear. Another is his bringing of the Transformers' conflict to Earth. Every casualty, human or Cybertronian weighs heavily on his spark. He does not show this side to his soldiers and never succumbs to despair. The Autobots need a decisive, charismatic leader and that is what he gives them. It was that leadership which turned the tide of the Great War.
Generation 1 Optimus Prime has appeared in numerous video games since the introduction of the Transformers series. He makes a cameo in the 1999 Beast Wars Transmetals video game for Nintendo 64, where he is killed by Megatron at the end of the campaign, showing what would have happened in the Beast Wars series with a Predacon victory. Prime is also one of the playable characters in the 2003 Japan-only Transformers game for the PlayStation 2 and the 2010 Transformers: War for Cybertron. Optimus Prime is also playable in the Hasbro Net Jet Transformers fighting game Transformers Battle Universe. Three versions of Optimus Prime are playable characters, including the first generation incarnation, his incarnations from the 2007 live-action film, and the incarnation from Transformers Animated. In this game, Optimus Primal is also a playable character. He is a regular character in the Nintendo GameCube and PlayStation 2 2003 fighting game DreamMix TV World Fighters. He appeared as a boss in a simple Flash-based video game on the Hasbro web site.[17]
Within G.I. Joe's headquarters, Optimus found Doctor Venom controlling a robotic suit made out of the remains of both Bumblebee and Soundwave. The battle between him and the Joes spilled out into the open and into another battle, where Decepticobra was attacking the United Nations. As more factions joined the brawl, Optimus yanked Bumblebee's components free from Soundwave's body and took to the skies, back to Cybertron. Expelled from the Garden There, he was able to reunite Bumblebee's body with his head. Headmasters
The lowest priced toys in the Armada line were three-packs of Mini-Cons. Each larger price point consisted of an Autobot or Decepticon who came with a Mini-Con partner. Mini-Cons could be used to unlock a variety of features on each larger robot, such as firing weapons, electronic lights and sounds, or alternate modes. Some three-pack Mini-Cons combined into other forms or had additional features. According to the storyline, Mini-Cons also enhanced the power of other Transformers, giving incentive to collect as many of them as possible.
