Four million years ago, Optimus Prime ended a Decepticon attack on the Ark by directing it towards prehistoric Earth. When both factions reawakened in 1984, Optimus Prime and the Autobots fought the Decepticons on numerous occasions until 2005. During an attack on Autobot City on Earth, Prime fell in battle against Megatron and passed the Matrix of Leadership to Ultra Magnus.
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.
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.
Power of the Primes "Evolution Optimus Prime" transforms from a truck with a trailer into a robot and back. The individual truck transforms into his "Orion Pax" form based on his appearance in the Generation 1 episode "War Dawn", and he is able to form the core of Optimus Prime's robot mode. His trailer forms Prime's entire body, and his ion blaster can be split into two weapons. He includes the Matrix of Leadership, which can store in his chest in the 'Evolved' form. The center of his Matrix of Leadership can be replaced with any Prime Master. In an undocumented feature, his rifle can be stored on his back as Optimus Prime by pegging it into Orion Pax's hands.The Takara version of the mold lacks the production numbers located at his right shins. Depending on the individual copy, Optimus Prime is prone to having a number of quality control issues: ranging from two left/right arms and/or legs/feet on the evolution armor, to lacking stickers on the trailer pieces.
The earliest releases of Energon Optimus Prime have no ridges on the inside of the chest windows and a different head sculpt featuring an Optimus Primal-style mouth-slit in Prime's mouthplate. This was soon replaced with a full mouthplate, and it was this version of the toy which appeared in the Energon cartoon and was released by Takara. Other changes made to Takara's version of the toy involved a chromed front grill, more vibrant plastic colors on Digger-3 and Submarine-4, a darker blue plastic on Prime himself, and more intricate paint operations. Takara's release lacks the electronic sound effects seen in Hasbro's version, which were commonly gutted for the Japanese releases of any Autobot toys who had them, though Prime retains his light-up chest.
The first Nightwatch Optimus Prime is an extensive redeco of the previously released Leader-class Optimus Prime, replacing most of his red and blue with different shades of blue and black. In fact, he resembles the original Diaclone Powered Convoy color scheme of Generation 1 Ultra Magnus's truck cab. The previously blue and red flames have been replaced with silver flames, while various other decos have been replaced by copper.
Another release of the Leader Class Optimus Prime figure, now redecoed from the original Revenge of the Fallen Leader Class mold, but with the gimmick-less arms from the Supreme Class retool, and a pair of articulated fingers which was not previously used for the original release. He also retains his pair of Energon Swords and Hooks, and his Knuckle piece. He also retains the fuel tanks that can combine to form his ion blaster. In terms of deco, he features a darker plastic color and paint (which resulted in a two-tone shades of silver & gunmetal), which is meant to go with this line's Jetfire.
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.
Prime comes with all the accessories of his previous release, although his ever-changing ion blaster is now somewhat confusingly cast in blue plastic. He features one major additional accessory: an electronic display base sculpted with the image of the Matrix and the Autobot insignia. Pressing the insignia's crest triggers a series of electronic soundbytes, mostly quotes from the movie recited not by original actor Peter Cullen, but by Hasbro's in-house actor, Ron Hayden: "Autobots, transform and roll out!", "I want you to make a special run to Autobot City," "Megatron must be stopped!", "All we need is a little energon, and a lot of luck," and two samples of the classic transformation sound effect, one ascending, one descending.
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. 
In the third nexus, Optimus oversaw Ironhide testing Sparkplug's latest invention, the Sun-Pak, a miraculous device capable of fuelling a Transformer for an entire Earth day after being charged for only an hour in sunlight. As the trial-run wound down to an end, the Decepticons suddenly burst into the Autobots' secret underground testing facility, forcing Optimus to decide whether to order a tactical retreat, or have his Autobots fight the intruders despite his troops' low energy reserves. If he chose to stand and fight, he had the additional choice to either make the Autobots concentrate on Starscream, who is leading the charge against the Autobots, or divide his troops' attention onto all of the Decepticon assailants. If Optimus chose to attempt to eliminate Starscream once and for all, the Decepticon Seeker would beg for mercy, forcing Optimus into a choice yet again: accept the snivelling Decepticon's surrender, or continue his attempt to end Starscream's evil once and for all. Accepting Starscream's surrender spells victory for the Autobots, whereas ignoring Starscream pleas ultimately leads to Sparkplug being kidnapped by the Decepticons, necessitating Optimus to send Buster, Blaster and Bumblebee on a perilous retrieval mission while the other Autobots recharge at the Autobots' home base.
He made it out of the building and ran into the real Sunstreaker, who blasted the 2 clones following Hot Rod. Sunstreaker ignored Hot Rod's warning about Scorponok's army and stormed into the building so Hot Rod painfully wired himself to send a distress signal. When Sunstreaker's real head was later disabled by Hunter, the Headmaster clones shut down, which Hot Rod explained to Grimlock. The group was surprised by the arrival of Shockwave, but Ultra Magnus had heard Hot Rod's distress call and was on his way to Earth. After Scorponok knocked out Sludge and Grimlock tended to him, the remaining Dynobots offered Hot Rod a lift aboard the Monsterbots' ship. He refused though, and made it back into Machination HQ to take care of something "personal". He eventually found Scorponok's real head. Hunter also showed up and let Hot Rod know how to disable it, but before he could do so, Scorponok grabbed him. Before Scorponok could crush Hot Rod's head, the Dynobots showed up and began to battle Scorponok. Hot Rod told Swoop which wires to sever, and he did just that, reducing Scorponok to a catatonic state. Ultra Magnus arrived took everyone back aboard his ship, which later docked with the Ark-32. Within 3 days, Hot Rod was fully repaired, with a new body form design.
After a thousand years of war on Cybertron, the planet was shaken from its orbit and risked being smashed to pieces by an asteroid field. Optimus decided to take a group of Autobots in the Ark and destroy the asteroids, but they were attacked by the Decepticons, and Optimus crashed the ship on Earth. Four million years later, the Ark repaired them, and they encountered Sparkplug and Spike Witwicky. Sparkplug suggested to Prime that the Autobots tap the volcano they'd crashed into for power. The two humans also warned the Autobots of an impending Decepticon attack, and Optimus laid a trap. Unfortunately the Decepticon forces attacked from all directions, and Starscream's null-ray put Optimus out of commission. Luckily Sparkplug easily fixed him, and his fast recovery inspired the Autobots to chase the Decepticons off. Optimus vowed to protect this new world. Battle for Cybertron
Optimus Prime is the leader of the main group of Autobots in the iteration of the Transformers franchise primarily marked by the 2010 computer animated series Transformers: Prime on The Hub. Optimus Prime was created as the last of the Thirteen Primes, the first generation of Transformers, each created directly by Primus as a band of unique warriors to combat and defeat Unicron. Upon his creation, Optimus united the Thirteen by his greeting All are one. While all of the other members of the Thirteen each possessed unique abilities and artifacts, Optimus wielded no special powers or weapons. It was only through his vision and courage that allowed the Thirteen to finally defeat Unicron. Reborn through the Well of All Sparks, Orion Pax became Optimus Prime, a veteran military commander and second in command who wields an ion blaster and a double bladed energon axe. He became the leader of the Autobots after Sentinel Zeta Prime fell in battle, but is not certain he wants the responsibility.
In just seven years, from 1997 to 2004, the number of elements in the company’s inventory exploded, ascending from slightly more than 6,000 to more than 14,200. So did its range of colors, which climbed from the original six (red, yellow, blue, green, black, and white) to more than fifty. As the number of components and colors mounted, soaring supply and production costs plundered the company’s bottom line. Here’s why.
If Optimus ordered his troops to come to the humans’ aid, they found themselves taking part in a struggle in futility, as the entire town was near-weightless, meaning they couldn’t put the humans anywhere where they wouldn’t float away once more. Then, the Autobots heard Decepticons approaching. Helpless in their current position, the Autobots were quickly eradicated by the Decepticons.
Part of the first wave of Bot Shots Series 1 launchers, this repaint of Optimus Prime comes with a large trailer that pops open to form a battle station with a spring-loaded launching platform. He appears to have the same plastic colors as the single release, and the same set of paint operations, but his paint is done in different shades, having glossy dark blue paint and glossy bright red paint. The black part of his launcher is sculpted to look vaguely like the repair done that is part of Generation 1 Optimus Prime's repair bay.
Optimus Primal, leader of the Maximal faction in the Beast Wars animated series and toy line, is not Optimus Prime. Primal is one of the Maximal descendants of the Autobots, who took the name to honor Optimus Prime. The same applies to the Megatron of this era. Before the animated series began, Hasbro envisioned Prime and Megatron as their beast counterparts, but once the animated series began, this had already been changed. Design elements, such as Prime's mouth-plate slitted to add an actual mouth for the animated series and the first mini-comic that came packaged with the toys, suggest this. Nonetheless, Optimus Prime and Megatron were a major reason the Beast Wars began, as Megatron's Predacon namesake traveled back in time seeking to alter history and insure that the Decepticons triumphed over the Autobots.
This gold vacuum metallized (save for his black joints, which they were made out of unpaintable plastic) Protoform Optimus Prime figure was featured as a Lucky Draw giveaway (along side similarly gold vac-metal versions of Voyager class Optimus Prime and Protoform Starscream) in the December 2007 issue of TV Magazine. Released in 2008, only 5 pieces were made, making it one of the rarest Lucky Draw figures; the images at right represent the only known photographs of it.
