In the animated series, Optimus Prime was originally in the Autobot Academy and friends with Sentinel Prime and Elita One. When Elita is lost on a planet dominated by giant spider-like aliens, he blames himself for leaving her behind, where she supposedly dies in the explosion of a wrecked Decepticon warship loaded with Energon. Sentinel doesn't forgive him for losing her and Optimus takes full responsibly for Elita's demise. Ultra Magnus, who had high hopes for him, expels him and thus bars him from any position of the Elite Guard. However, Magnus pulls some strings so that Optimus could be captain of a strange Space Bridge repair crew composed of an old grumbler of a war vet named Ratchet, a fledgling Bumblebee, and his fellow cadet, Bulkhead. Optimus is given command of the starship Omega Supreme.

Although the original Japanese incarnation of Transformers: Cybertron, known as Transformers: Galaxy Force, was produced apart from Armada and Energon, the series, as originally conceived by Hasbro, was as the third part of the trilogy. The English language dub of the series treats it as such.[11] Consequently, inconsistencies arise between Cybertron and the other two series, but have been explained by the Cybertron comic book, available exclusively through the Official Transformers Collectors Club, as the result of fluctuations in the fabric of reality caused by the Unicron-induced black hole.
A single-packed version of the battle damaged Voyager Optimus Prime toy from the Sam's Club exclusive three-pack. Although the assortment number and the general packaging style seemed to indicate that this might be a Best Buy exclusive, this has been confirmed to be an "international market" exclusive. It has been released in Asia, but will presumably not be available in the USA outside the Sam's Club three-pack.
Prime's firing missile and Mini-Con activated gimmicks remain accessible in this mode, but look a bit doofy if you deploy them. The initial Hasbro release of Prime had tabs in its Super Mode shoulders that prevented them from rotating above the horizontal default position, so as not to break the wires that run through the toy's right arm. Coupled with the limited elbow joints, this left Optimus Prime able only to point his weapons towards the ground, and the tabs were removed on subsequent editions of the figure.

On a mission with the Triggerbots to stop Megatron from claiming the Underbase, Prime was forced to jettison the massive databank into space to prevent anyone from acquiring its power. With this action, he proved his wisdom and skill to the Autobot Council of Elders. He continued to move up in rank, eventually becoming the field command over the Autobot armies.

This figure was originally conceived by Hasbro to be another character (exactly who is unknown), rather than Optimus Prime, but Takara insisted that the toy be made into Optimus to help it sell well in their markets, as the vehicle mode was no particular draw, given its scarcity in Japan. Reportedly, the figure cost twice as much as other Alternators to construct, so Hasbro had to bow to this demand so Takara would help fund it. Ironically, Takara eventually wound up soliciting the figure not as Prime, but as his Super-God Masterforce lookalike, Ginrai (perhaps connected to the Powermasteresque headsculpt), before its Japanese release was cancelled and moved over into the Kiss Players toyline (see below).
The largest Action Master set, this incarnation of Optimus Prime is a non-transforming action figure which comes with the "Armored Convoy", a large, heavily armed tractor trailer. The cab of the truck transforms into a small jet that can seat one Action Master figure, while the trailer itself converts into a larger battle station with turrets that several Action Masters can man. The sculpt of the Prime figure itself is closely based on his character model, albeit with a coloration that seems to have been based at least partially on the small robot form of his Powermaster body.
Entertainment Pack Optimus Prime is a slight redeco of the SDCC figure, with some deco differences between the SDCC release; this version has gray windows instead of blue and is missing some of the silver deco on the helmet and roof/feet, as well as the yellow paint on his lights. His midriff is also darker. Optimus also comes with a similarly-scaled Megatron and PVC figurines of Jack Darby, Miko Nakadai, and Raf Esquivel.

In Super Mode, Optimus Prime can combine with Leobreaker to form "Savage Claw Mode", which sees the feline Autobot become a gigantic clawed arm for his leader. Alternately, if Prime's backpack is removed, he can merge with Wing Saber into "Sonic Wing Mode", with the aerial ace forming a new winged backpack and chestplate for Optimus, and providing him with new hand-held sword weapons and firing missile launchers that connect to his Super Mode boots. The nature of the combination means that the two partners cannot combine with Prime at once—at least, not without physically removing one of Prime's own arms.

After weeks of Decepticon silence, Optimus Prime decided to get proactive and sent out patrols all over the planet to try and flush the villains out. None of the patrols reported back with any success, however, and Prime realized that there was one area of the planet that his troops had deliberately ignored: the mysterious "Nebulos Triangle". Quickswitch, Scoop and Quickmix were sent into the Triangle, and they did indeed discover and foil the Decepticon plot going on in the area. Decepticons Underground
The series begins when Optimus and his crew, after picking up a disillusioned ninja named Prowl, are sent to clear rubble from a space bridge passage. There, the Autobots stumbled upon the Allspark and are immediately attacked by Megatron's battle cruiser, the Nemesis. Through treachery by Megatron's second-in-command, Starscream, Megatron was fragged and the Autobots crashed on Earth in the early 21st century. After being in stasis under Lake Erie for 50 years, the Autobots awaken in Detroit of the near future, where they immediately discovered humans in need and became heroes of the city. During the battle for the possession of the Allspark, Optimus goes offline after defeating Starscream, only to be revived by Sari Sumdac and her Allspark-infused key.
In his stronghold, Serpent O.R. questioned Prime about his own worthiness to carry the Matrix, but Optimus broke free of his chains and aggressively ordered him to surrender. The Art of War #4 A group of Decepticons broke in and nearly took Prime apart, but not before Serpent O.R. took the Matrix for himself and changed into the massive Serpentor Prime. The Matrix showed Serpentor Prime the error of his ways but as he was about to commit suicide Cobra Commander tripped a device and took over Serpentor Prime's body. Moments before he crushed Arcee, a severely damaged Optimus Prime threw Hawk toward the Matrix but warned the human not to touch the artifact. Hawk did so anyway and through a quasi-mystical transfer of power Serpentor Prime was vanquished.

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 returns in Transformers: The Last Knight, which is set three years after the events of the previous film. Having been frozen in the vacuum of space, Optimus has been drifting on the far reaches of Earth's solar system for some time. However, he later crash-lands on Cybertron, its atmosphere reviving him. He then confronts the being currently in control of the planet, a powerful sorceress named Quintessa, who professes to be the maker he is searching for. Optimus is easily subdued by Quintessa, who convinces him that he destroyed Cybertron and reveals that the Earth is actually Cybertron's "ancient enemy" Unicron. Redubbing him "Nemesis Prime", Quintessa brain-washes Optimus and tasks him with retrieving her stolen staff, with which she plans to drain Earth/Unicron's life force so that Cybertron can be restored. Nemesis succeeds in retrieving the staff, but is hindered by Bumblebee, whom he engages in a fierce duel. Nemesis nearly kills Bumblebee, but when the normally mute Bumblebee suddenly speaks, urging Prime to remember who he is, the sound of his oldest friend's voice is enough for Optimus to return. However, Megatron, revealed to be in league with Quintessa, swoops in and steals the staff from Optimus. Prime is then attacked and sentenced to death by the Guardian Knights for aiding Quintessa, but he is saved by Cade Yeager, who convinces Optimus to correct his mistake. Optimus leads the Autobots in the attack on Quintessa's lair, during which he slays the Infernocons and defeats Megatron. Optimus then attacks Quintessa, distracting her long enough for Bumblebee to shoot and seemingly vaporize her. At the end of the film, Optimus and the other Autobots return to Cybertron, unaware that Quintessa is actually still alive.
This Japanese-exclusive vacuum metalized golden redeco of Super Base Optimus Prime, whose name means "Shining Golden", was available as a prize in several draws, including a colouring contest held in the pages of TV Boy magazine, and in-store lottery draws at Tobu Department Stores. Between the draws, at least 58 "Kinpika" Prime toys are known to have been given away, making it one of the more widely available Lucky Draw figures, comparatively speaking. It came packaged in a plain white box, and including all the accessories and features of the standard release of the figure, including a gold-chromed Sparkplug (or "Prime", as he's confusingly known in Japan).
Henkei! Henkei! Transformers Convoy is a redeco of Classics Optimus Prime. He features a significantly altered colour scheme, generally to make the toy more closely resemble his appearance in the Generation One cartoon and the original toyline. His truck mode features less silver paint striping, but compensates by vacuum-metalizing the entire grill/fender area silver chrome. In robot mode all of his previously grey plastic has been replaced with red plastic and mostly painted silver (or in case of the grill & bumper, chromed), along with smaller decos. Since Henkei! toys do not feature a heat-sensitive rubsign, Henkei Convoy has two Autobot sigils tampographed onto his shoulders.

Sure enough, in 2009, when the Hytherion's colossal claw-marks appeared on planets throughout the solar system, Prime's other-dimensional incarnation returned, bringing with him a "Vibrant Red" Vector 109 auto-avatar with which Prime fused. In that instant, he was reborn as part of the Alternity, a manifold being who encompassed all the different incarnations of Optimus Prime through the multiverse at once. Prime reached his hands heavenward and peeled back the layers of reality, exposing the gargantuan fanged maw of the Hytherion looming above the Autobots. From Here to Alternity
The figure seems to have some transformation scheme & design related problems in it: The front truck cab's upper two pieces are supposed to be pushed to the front in robot mode, but the piece keeps collapsing back due to looseness when the figure is standing straight (Though pressing the two halves together firmly tends to reduce this issue for a while), while the tab underneath the truck grill does not connect well with the bottom port. Additionally, his 5mm compatible hands have a slight problem with wielding weapons with short 5mm posts.
Optimus Prime was given the Matrix by Primus himself, and used to be friends with Megatron. Prowl is his closest friend and Ratchet is his oldest. Searching for Energon, the Autobots landed on Earth, but were followed by the Decepticons. With the help of their human allies, they bested their foes, and knowing they would return, decided to stay and wait to defend the planet once more. Optimus Prime was proud to be an Autobot. I Am Optimus Prime
This Optimus Prime is a new mold that matches the character's more cartoony and simplified appearance in the Q-Transformers: Mystery of Convoy Returns cartoon. The "Watashi ni ii kangae ga aru" added to his name means "I have a good idea" (私にいい考えがある). A line originally spoken by G1 Optimus Prime at various times in the Japanese dub of the original cartoon, it has a reputation as a catchphrase of his among Japanese fans and has been reused by many Optimus Primes since, including the Prime in the Q-Transformers cartoon.
When Starscream attacked a power plant with the aid of his brainwashed ally, Skyfire, Prime carried Grimlock to the scene of the battle on the back of his truck mode. The Enemy from the Arctic During the conflict that followed, Prime's suspicions about Wataru were confirmed when the boy manifested a barrier to protect himself and Bumblebee and to help Skyfire overcome the influence of Starscream's mind-controlling helmet. Wataru was a Booster as well! Wataru's Power His past experiences naturally made Prime hesitant to put Wataru's power to use, but Osamu Kihara made the point that Wataru's power was invaluable for hunting down shards of the Energon Cube. Prime and Wataru headed out to investigate a local relic that Kihara suspected was a cube shard, and Wataru's powers soon confirmed the doctor's findings. Just as Prime was about to report back to Kihara, however, Megatron struck, demanding that Prime hand over both the shard and Wataru. Prime attempted to feign ignorance of Wataru's powers, but Megatron ignored his bluff and encouraged him to hand the boy over, lest he cost another Booster their life. Driven into a rage by the stinging barb, Prime violently attacked Megatron with his energon-axe, but as the duel raged, Megatron continued to question Prime's beliefs and his attitude. Unable to deny Megatron's accusation that he had hoped to use Wataru's power to defeat him, Prime lost his concentration and was taken down by the Decepticon leader. Despite what he had learned about a previous Booster dying, Wataru stayed true to Optimus and activated his powers, healing the Autobot's wounds and powering up his energon-axe into a huge sword. Summoning all his energy, Prime took down Megatron with one almighty slash, then collapsed into stasis lock. Optimus Prime's Secret

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]
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.
In Transformers Ongoing, which takes place two years after the events of All Hail Megatron, the Autobots would remain on Earth as Prime feared the return of the Decepticons. Unfortunately, this led to the capture of a number of Autobots by Skywatch, including Windcharger, Gears and Prowl. Hot Rod was reformatted into a Pagani Zonda. Already frustrated, he lashed out at Optimus, accusing him of keeping the Autobots on the planet because he needed someone to protect and demanding he be allowed lead a team to rescue Prowl. An admonished Prime agreed to a covert operation, but with Ironhide along to watch over things. While Prowl was freed, it turned out the humans had used him as bait to draw the other Autobots in. However Wheeljack's new shielding protected Hot Rod's team from Skywatch's inhibitors and in a panic the soldiers switched to lethal measures. Hot Rod was targeted and Ironhide was killed protecting him. An enraged Hot Rod turned on the humans, damaging their equipment and machinery.
