As leader of the Autobots, Prime headed up their mission to search for new sources of energy to revitalize the depleted Cybertron. Optimus vowed to Elita that he would return from his mission for her, but just before the launch of the Ark, Optimus was mistakenly led to believe that Elita was killed. Shortly after its launch, the Autobots' craft was attacked by the Decepticons' space cruiser, the Nemesis, and boarded by Megatron and the Decepticons. In the ensuing struggle, the G-forces of a nearby planet pulled both craft down, and the Autobots' ship crashed into a volcano, thrusting all the occupants into emergency stasis. Four million years later, in the Earth year 1984 A.D., a volcanic eruption jarred the ship's computer, Teletraan I, back to life. The computer reactivated the Decepticons, programming them with new Earth-based disguise modes. As a parting gesture, Starscream fired upon the Autobot ship, creating a landslide. The vibrations from that landslide knocked Prime into the path of the computer's restoration beam, restoring him to life, thus beginning the war anew on Earth.
The main Prime line in Japan, while mostly using the same molds, was quite a bit different from the Hasbro version. Hoping to snag a slightly-older market, the toys were given a bit of "model kit" vibe. Paint operations were reduced and replaced with old-fashioned sticker sheets, so you had to customize/complete the toy itself... and then there was the blatantly model-kit Arms Microns packed in with every toy.

When a two-part race was being held with a massive supply of oil and gasoline as the prize, both the Decepticons and the Autobots badly wanted to win it. Megatron entered the race by hiding himself inside a hollowed-out car and harassed Cliffjumper all throughout the contest. When Prime discovered the car was being driven by his arch foe, he swiftly pulled a telephone pole out from the ground and used it to bash the mortal hell out of the cheating Decepticon. Thanks to Prime's violent intervention, Cliffjumper was able to win the race. Afterward, Optimus Prime celebrated the Minibot's victory with a gargantuan smile as all the Decepticons starved to death. The Great Car Rally

Optimus Prime landed in the Himalayan Mountains with G.I. Joes Flint and Hawk. As they searched the area, the trio was attacked by Bludgeon in his Pretender shell. Prime whacked him with his energon-axe and in return Bludgeon bearhugged him and coated him in metal-eating slime. Hawk, still carrying power from the Matrix, helped Prime break free. Optimus then shot his way into the hidden kingdom of Cobra-La.

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 "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 Garry Chalk, who previously voiced Optimus Primal in Beast Wars and Beast Machines.
A younger version of Prime Optimus Prime is one of the playable Autobot characters in the 2010 video game Transformers: War for Cybertron. In the Autobot campaign, he starts off as Optimus, a warrior who rallies his fellow autobots against the Decepticons following the reported death of their leader Zeta Prime. He succeeds in defending the Autobots' home city of Iacon from Starscream and his forces. Optimus then receives a distress call from Zeta Prime. Knowing that this is most likely a trap set by Megatron, he proceeds anyway with a rescue mission. He lets himself, Bumblebee, and Sideswipe be captured by the Decepticons and is sent to a prison in Kaon, the decepticon capital, in an elaborate scheme to free Zeta Prime and all imprisoned Autobots. He frees all the other prisoners, and defeats Soundwave and his minions Frenzy, Rumble, and Laserbeak, but he is too late to save Zeta Prime. After taking Zeta Prime's body back to the Autobot high council, he is bestowed upon the well earned title of Prime.
Part of the first wave of Prime Series 2 Cyberverse Commander Class toys, Optimus Prime is a smaller-scale toy, and features translucent plastic for his torso so that the toy can be illuminated using the electronic lights featured in the larger playsets. He comes with two translucent "battle cannon" weapons which feature multiple 3mm posts and ports, allowing them to be held by his hands, or store/mount onto numerous ports on his person. Additionally, he features a 5mm port for a trailer hitch.

While stock photos and renders show the figure with a faceplate, this image posted by the Transformers Facebook page shows him with his mouth exposed. This was later found as a variant at least once. A running change was made, changing the blades to be more translucent. The semi-translucent blades release features a date code "73461", whereas the translucent orange blades version features a date code written as "80171".
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.

In the animated series, Optimus is able to fire short-range optic blasts, project holographic maps, and deploy hydro-foils, designed by Wheeljack, to traverse bodies of water with ease. In the animated series, Optimus was also given the ability to retract his right hand unit and replace it with a glowing axe.[7] Across the assorted continuities of the original Transformers universe, there have been various interpretations of Optimus Prime. One of Prime's most notable characteristics over all continuities his unswaying commitment to leadership by example. The animated series's version of Optimus Prime is depicted as a straightforward, wise, and upbeat battlefield general. Additionally, the animated series's version of Optimus dislikes rap music, putting him at odds with music-loving characters like Blaster and Jazz. In the Marvel Comics series, in addition to these characteristics, Prime is secretly plagued by self-doubt and a conflicted sense of pacifism that often makes him an extremely reluctant warrior.
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. Kingdom of Giants

In search of new energy sources, Optimus led a team to central South America. When they spotted Mount Sheelah, their two human friends John and Tim Gordon explained volcanoes, and, believing it to be of possible use, the Autobots went to examine it. During a battle with the Decepticons over the volcano, Optimus was convinced by the two humans to retreat, ultimately saving them when Mount Sheelah erupted. Terror of Mount Sheelah After discovering that the Decepticons were kidnapping humans, Optimus sent Bumblebee to scout the Decepticon base. When Bumblebee returned with the Decepticons' global crystal, Optimus was able to use it to blackmail the Decepticons into letting the humans go. Bumblebee to the Rescue

The first release in the Asian-exclusive Asia Premium Series toyline is an extensive redeco of the previously-Japanese exclusive Striker Optimus. He features a comprehensive paint scheme directly based on Jetpower Optimus Prime, with blue pinstriped flames, lots of silver paint, and vacuum metallized parts, although his hands are left unpainted in favor of painting his mirrors silver. Along with his standard accessories, he also comes with 2 battle blades, which were previously exclusive to Toys"R"Us Japan. He features the "We must stop the Decepticons!" voice chip, but batteries are not included. Rather helpfully, his instructions are supplemented with text instructions written in English for all the steps, as well as the additional photographs used for the previous Striker Optimus toy.
A black and red version of the First Edition deluxe Optimus Prime could be seen in the San Diego Comic-Con 2011 Transformers slide show, inside a mock-up of the wearable Matrix of Leadership package done for the convention that year. This figure was presumably a test-shot, as it seems to share plastic colors with Generations Sky Shadow (who was, coincidentally, first revealed at that same Comic-Con).
A redeco of the Super Optimus Prime mold with a primarily red cab, much deeper blue, and a Prime Force uniformly colored in black was planned to be released with Smallest Transforming Transformers Generation 1 Optimus Prime as a Target exclusive. The toy got far enough along in development to have package artwork created by Dan Khanna, which was later revealed online, but it was canceled shortly before making it to full production. Its red, white, and black coloration earned it the festive nickname of "Santa Prime" among fans online.
Super class Energon Optimus Prime transforms into a Cybertronic short-nosed truck cab. A switch on his back offers four selectable sound effects, each one corresponding to one member of the Prime Force, the four drone vehicles contained within Prime's parallelogram-shaped trailer. A tiny, slightly recessed button above the switch activates the sounds. When Prime transforms to robot mode, the trailer stands upright to become a launch base of sorts for the Prime Force, with three of the trailer's four storage compartments featuring launching mechanisms that propel the vehicles into action. The Prime Force consists of Fire-1, a fire truck with an extending ladder and rotating turret; Copter-2, a helicopter with spinning rotors; Digger-3, a drill tank with a gear-wheel-activated spinning drill; and Submarine-4, a submarine with opening capture claws beneath its bow. The four interchangeable drones can combine with Prime to create his Super Mode; any drone is capable of forming any limb. When in Super Mode, Prime's chest panels are opened, in turn pressing a button on his side that creates more electronic sounds and lights up a red LED in his chest, representing the Spark of Combination.

The TakaraTomy version, part of the first wave of Movie Advanced Series toys, is dubbed "Classic Optimus Prime", and opts for a deco closer to Prime's previous on-screen appearances, omitting the blue paint on his feet and hands to reveal the gray plastic underneath, and adding new paint details all over. Instead of painting it in clear light blue, his light-piping eyes is neutered with opaque light blue paint. In terms of quality control, at least one sample has missing it's silver paint on the head's left cheek.
Several Autobots and Decepticons, including Optimus Prime, were reformatted into will-less war machines under the control of Cobra. During an initial attack on a human peace conference, Cobra's remote control of Optimus (whom they had nicknamed "HISS-14") mysteriously failed. G.I. Joe vs. the Transformers #1 Later at Cobra's island headquarters in the Caribbean, Cobra scientists pulled Optimus apart to find out what was impeding their commands. As this analysis took place, Optimus reverse hacked into Cobra computers until they shut him down in a panic. G.I. Joe vs. the Transformers #2 Despite this, Prime sent a viral message out to hundreds of email addresses that included the coordinates of Cobra's base. The message was intercepted by G.I. Joe who teamed up with Wheeljack and Bumblebee. After Wheeljack broke the remote control over the Transformers, Prime went after Cobra Commander. G.I. Joe vs. the Transformers #3 More than a bit frightened of a giant robot gunning for him, the human released Megatron, who was trapped in gun mode. Megatron transformed and fought Prime to a standstill until other Autobots came to back him up. G.I. Joe vs. the Transformers #4

The main selling point of the toy is the ability of the truck cab to combine with the trailer to form Super Optimus Prime. The cab portion folded in half and sat in the chest cavity of the trailer's torso, giving him the classic Optimus Prime truck-chest appearance. The two double-barreled cannons were attached to his shoulders and a large, separate head piece was mounted onto the hole on top of the truck cab.
In late 1993, Hasbro relaunched the Transformers franchise with the Generation 2 line, with production again largely being done by Takara. The subgroups concept was done away with for the first year, but there were no new molds or characters. Generation 2 re-used the molds for many of the characters from the 1984 and 1985 line, but with mostly different color schemes and finishes, as well as different weapons and accessories. Megatron's figure was released later on. As noted previously, Megatron's original alternate mode, or "transformation identity", was a handgun with attachments, but in Generation Two, this was changed to a tank due to safety and security concerns. Most of the 1994 figures were re-releases or recolors of European G1 releases.
A Voyager class figure that transforms from semi-trailer truck to robot. Head features retractable face plate. The figure's main gimmick is a spring-loaded mechanism that spins the lower torso during transformation to robot mode. Trailer detaches and transforms into a giant Ion Axe or jet pack. Prime's gun can be filled with a small amount of water. Some variants of the figure come with the Autobot symbol printed on his left shoulder while others do not.
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.
Rodimus Prime is a fictional robot superhero character from the Transformers robot superhero franchise. He was formerly known as Hot Rod and was first seen in The Transformers: The Movie but was reformatted into Rodimus Prime when he received the Autobot Matrix of Leadership from his mentor, Optimus Prime, the leader of the Autobots, and assumed the role of the movie's protagonist. Hasbro has used the names Autobot Hot Rod, Rodimus, and Hot Shot as replacements for later characters, due to trademark issues with the name Hot Rod. His alternate mode varies between depictions, but usually possesses a red, yellow, and silver paint job.
This Optimus Prime is an extensive screen-accurate redeco of the Dark of the Moon Supreme Class/Leader Class Striker retool, using the Ion Blaster accessory from the Buster Optimus Prime and the Toys R Us Japan-exclusive battle blade accessories. He also comes with the Knuckle piece and the Battle Hooks and uses the 2-2-1 articulated fingers featured from the second Asia Premium Series release. He also features a Japanese language sound box for his voice gimmick, replacing Peter Cullen's "I am Optimus Prime" voice line.
Rodimus also appeared in the Dreamwave Energon Comic. In this continuity Rodimus's history in unclear, but he seems to be a veteran Autobot assigned to Earth. He acts as a mentor to many of the less experienced Autobots: for example he was the first to congratulate Ironhide when he overcame his fears to defeat Tidal Wave. He was one of the defenders of Toronto alongside Hot Shot, Red Alert, Hoist, Beachcomber and Thrust, battling against Divebomb and a swarm of Terrorcon clones before receiving help from a very unlikely source - Megatron, resurrected in a new body by Optimus Prime. The subsequent counterattack routed the Terrorcons.
Optimus Prime was subject to several molding and color variations in his early days. The earliest release of the figure featured larger fists, a gun with a thick, round barrel, a slightly-differently shaped gas pump, grey rockets, a grey Roller, a grey launcher in his Combat Deck, and metal plates in the floor of the Combat Deck (a holdover from the Diaclone version of the toy, to which the magnetic feet of the pilots could cling). In short order, his fists were slimmed down, the gun's barrel was pared down to a more slender form, the gas pump's shape was altered, the rockets and launcher were recast in black plastic, the metal plates were removed from the Combat Deck, and Roller's color was changed to a light blue. Along with Roller's color change, however, the Combat Deck's drone pod also became light blue, and a third running change soon followed that saw it restored to its original darker blue, and Roller changed along with it. These modified components would become the default accessories used by subsequent reissues of the Prime toy would take, though Roller stills fluctuates back and forth between grey and dark blue, depending on how show-accurate each reissue wants to be.
