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.
The first generation Optimus Prime transforms into a Freightliner FL86 cab over semi truck. Within his chest is a mystic talisman, known as the Autobot Matrix of Leadership or the "Creation Matrix", carried by all Autobot leaders. When Optimus transforms, his tractor cab disconnects to become a sentient robot, and his trailer opens to reveal an ion blaster, forming a combat deck. The combat deck supports a mobile battle-station and command headquarters armed with assorted artillery and beam weapons that fire automatically. The combat deck can also serve as a radio antenna for battlefield communications between the autobots. The combat deck also included "Roller", a mobile scout buggy meant to scout behind enemy lines. When Roller is deployed, Optimus can see and hear what Roller sees and hears. Injury to one component is felt by each of the others. If the combat deck or Roller were to be destroyed, Prime could survive. However, despite the slight degree of autonomy they possess, the combat deck and Roller would not be able to survive without Optimus.
In a break from tradition, Energon Optimus Prime's large mode resembled a configuration similar to Voltron or to the Super Sentai action figures. This design was unpopular with many fans due to design issues with the toy. The small robot's body was large in proportion to his arms and legs which made the figure appear fat, earning it the nickname "Fatimus Prime" or "Obese-imus Prime". The 4 vehicles that combined with the robot were small, lacking the intricate detail that made other toys in the line popular. Fans were also angered by early releases of this toy in which the head was molded with a mouth rather than the traditional face plate design. Later releases of the toy eliminated the visible mouth feature.
This Optimus Prime is a new Voyager-sized Triple Changer mold, which transforms from robot to tanker truck to plane and back. His robot mode is heavily based on Generation 2 Laser Optimus Prime, whilst the deco appears to draw from Star Convoy. His Titan Master partner Diac transforms into his head (but any Titan Master figure is compatible). Like all Titans Return Voyager class figures, he has built in mechanisms to "bulk up" his noggin. In his case these are spring-loaded pylons. His robot mode also features fake truck windows.
Sold by Hasbro Toy Shop at various conventions, Pepsi Optimus Prime is a repackaging of a virtually unaltered 2005 Japanese Pepsi Convoy. (Again, his stacks are shortened for safety reasons.) However, this U.S. release is, officially, a different character. Whereas the Japanese release's bio explicitly identifies the product as a separate character from Convoy (created with help from NASA, no less), the U.S. bio conversely indicates that their version of the character most definitely is Optimus Prime. His motivation for schilling Pepsi is, apparently, that he wanted a new disguise but basically couldn't be arsed to actually reformat into a new altmode.
Optimus Prime is armed with two large rifles formed out of a combination of both smokestacks and fuel tanks. These rifles peg into lower arms with grips for his open hands. The under-slung fuel tanks can fire spring-loaded projectiles. In vehicle mode, both smokestack rifles can be deployed as twin cannons, and this mechanism can also be used to store the rifles and deploy them as shoulder guns in robot mode.
The TakaraTomy release of Optimus Prime has considerable differences from the Hasbro release. His blue and red plastics are darker and metallic, his translucent blue plastic is darker, and a few of his paint operations have been omitted and replaced with customer-applied foil stickers, such as his shins, feet, headlamps, and insignias. His legs, outer forearms and truck mode "sleeper cabin" side panels have been retooled to include 5mm post-holes as part of the line-wide "Arms Micron" gimmick. As such, he does not come with the Hasbro version's weapons, but instead an Arms Micron partner named O.P. who transforms into a weapon resembling Optimus's in-show blaster cannon. This version of the mold was also used to make Prime Nemesis Prime.
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.
A repaint of the Armada Supercon Optimus Prime, minus the Mini-Con, but instead had a Cyber Key with a Mini-Con port in it. Repainted to match Cybertron Galaxy Force Optimus Prime. This is supposed to be a drone which Optimus Prime controls to get into small places, built for him by Metroplex. Several paint variations of this toy exist, and early releases have the forearms swapped, just as had occurred with the last repaints of the mold.
In the "Transformers" film, the robots had more of an alien feel to them to fit the theme of an alien invasion. The robots (stated by Optimus Prime) in the film are actual sentient organisms and not just giant, mindless, and mechanical machines. The robots can also speak their own alien language sounding like what seems to be based on different pitches and frequencies. Alongside that, they gave them more alien features that probably wasn't mentioned in the comics or T.V. series such as a highly advanced exoskeleton, force field, and a special "alien meteoroid" mode which they transform into individually and arrive on earth in. The exoskeleton is a "self-regenerating metal" in which the aliens are composed of (stated in the film) that is the equivalent of living skin that heals itself.
In Transformers: The Last Knight, he is brother-in-arms with Bumblebee who he fought alongside with to foil the Nazi Party in World War 2. He speaks with a thick French accent due to being stuck in France for so long, much to his own embarrassment. He wields a special gun which can briefly slow down time. He is also the only Transformer who is shown to speak in vehicle mode. 
Optimus Prime is primarily voiced by Peter Cullen in most of his incarnations, who voiced him in the original series. Following the production of the 2007 film, Cullen reprised his role for the sequels and supporting media and would even voice Optimus in later series such as Transformers: Prime. Optimus has been voiced by a number of other voice actors in other series such as Neil Kaplan, Garry Chalk, and David Kaye in the series Transformers: Robots in Disguise, Unicron Trilogy, and Transformers Animated, respectively.
Two of his limbs are based on Armada Optimus Prime; one "normal" (Inferno helmet), one pre-Earth-body (Knock Out helmet). The main torso-bot is based on Generation 1 Optimus's original body. Another limb-bot is based on live-action Optimus (Soundwave helmet), and the remaining one (Ironhide helmet)... actually looks to be based on the Optimus-like-but-not-Optimus Micromaster Overload! The heck?
Offered as part of a Lucky Draw campaign in August 2004, this extremely rare version of Masterpiece Convoy is almost entirely vacuum-metalized gold, lacking any other painted detail or stickers. The parts which are not viable are molded in a flat golden plastic; the only exceptions are its rubber tires, the core of the Matrix and the energon-axe, which remain black, blue and orange, respectively. Whether or not the figure was intended to evoke Optimus Prime's entirely-golden appearance in the cartoon episode "The Golden Lagoon", when he was coated with electrum, is unknown; given that entirely chroming a figure gold is a fairly standard deco for Lucky Draw figures, it may just be happy coincidence more than anything else.
General Optimus Prime later attended a meeting of the Convoy held by Starscream. There, he assured the others present that he had been mistaken about the rumored Megatron's identity. Starscream was convinced, but the rest of the Convoy were savvy to the truth. The other Optimuses supported General Optimus Prime's decision, stating that if C-81 had earned the General's trust, that was good enough for the rest of them. Optimus was later seen hanging out with Spy-Eye on his off-time. Cybertron's Most Wanted
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. 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.
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.
