:''Optimus Prime is the [[Autobot]] leader from the [[Live-action film series|live-action film]] [[Continuity family|continuity family]]. He has [[Transformers: Rise of the Chevy Autobots|sometimes]] used the codename '''10-22'''.''

[[Image:Movieprime meettheautobots.jpg|right|300px|thumb|Hello, pretty bird. GIVE ME YOUR FACE.]]

'''Optimus Prime''' is the leader of the [[Autobot]]s. Long ago, he was the humble leader of [[Cybertron (planet)|Cybertron]]'s science division, which studied the [[AllSpark]], and were protected by [[Lord High Protector]] [[Megatron (Movie)|Megatron]]'s military. When Megatron was corrupted by [[The Fallen]], Optimus discovered that he was the last of the [[Dynasty of Primes]], hidden away when The Fallen destroyed their lineage. In response to Megatron's attempts to seize the AllSpark and conquer other worlds, Optimus assumed his proper [[Prime (rank)|title]] and rallied the Autobots to stand against the [[Decepticon]]s.

As obsessively as Megatron strives to achieve his objective, Optimus is equally as dedicated to stopping him, even at the cost of his life, his world, and—if necessary—his own people. It was on his order that the AllSpark was jettisoned into space, dooming Cybertron to a slow death and his people to a nomadic life. The sacrifices he has made weigh heavily on his [[spark]], but they must be done, for there is no other choice. He knows the ambitions that lurk in Megatron's spark, and they must never see the light of day. Lives must be kept free from the threat of Megatron's tyranny, no matter the cost.
This obsession with the defeat of Megatron has robbed Optimus of some of his early idealism. This has created a certain ruthlessness beneath his otherwise honest and caring personality. Prime is not one for second chances and is willing to consider any action that might lead to victory, short of directly sacrificing those he cares about.

===IDW ''Transformers'' movie prequel comics===
It was Optimus Prime's [[Prima|ancestor]] who finally vanquished [[the Fallen]] to another [[sarcophagus|dimension]] in the battle for the [[Matrix of Leadership]], {{storylink|Tales of the Fallen issue 4|Tales of the Fallen #4}} but his orphaned descendant who was hidden away from the Fallen grew up with no knowledge of what he was. {{storylink|Revenge of the Fallen issue 3|Revenge of the Fallen #3}} 

[[Image:Foundation1-literaldawn.jpg|left|thumb|300px|He's right, an actual literal dawn ''was'' involved.  Put those knives away, English majors.]]

Eons after the [[Dynasty of Primes]] were vanquished, Cybertron fell into dark times.  The [[AllSpark]] had been buried somewhere within Cybertron and been dismissed as a legend, and the planet itself lacked a star to orbit.  As energy became more and more scarce, Cybertronians segregated into tribes. [[Sentinel Prime (ROTF)|Sentinel Prime]], a being who claimed to be descended from [[Primus]] himself, found Optimus and recruited him into his cause. {{storylink|Foundation issue 1|Foundation #1}} Optimus and [[Megatron (Movie)|Megatron]] helped Sentinel Prime locate the AllSpark and harness a star for Cybertron to orbit, and these fantastic acts united Cybertron for the first time in known history.  But Sentinel Prime had grown old and weary and refused to lead the Cybertronians, and, in confidence, he revealed to Optimus that he was a [[Prime (rank)|Prime]], and that he ought to succeed him as leader. But Optimus could not believe he was a Prime. However, he believed by investigating Cybertron's history he could bring some of the good the Primes created back to the world. Sentinel redrew his plans for Cybertron, having Optimus lead the archaeological [[Science Division]], while placing Megatron in charge of Cybertron's [[Defense Force]]. {{storylink|Foundation issue 2|Foundation #2}} Little did they know that Megatron had been eavesdropping, and Optimus's brother came to a jealousy-inspired conclusion. He didn't believe Optimus Prime had the ability to competently lead Cybertron, and that this series of events would one day pit the two against each other, until one was dead. Megatron vowed that it would not be him. {{storylink|Foundation issue 1|Foundation #1}}

[[Image:Defiance1 Megs Prime argument.jpg|right|350px|thumb|"Hey, I wanted a mouthplate!"]]

For two generations, Optimus and Megatron ruled Cybertron together. The two personalities created a balance; Prime was fair while Megatron was firm. {{storylink|Movie Prequel issue 1|Movie Prequel #1}} After an increase in [[Malcontent]]s disrupting Sentinel's order, Megatron intimidated Optimus into giving him supreme power in defense of the planet. {{storylink|Foundation issue 2|Foundation #2}} When ''Lord'' Protector Megatron toured the excavation site near the AllSpark [[Simfur Temple|temple]] at [[Simfur]], he and Optimus clashed over several issues. While Optimus wanted to take the investigation slowly, all Megatron cared about was whether the site contained power similar to the AllSpark. Optimus nettled Megatron when he reminded the Protector that the science sector was in charge of scientific and archaeological discoveries, and that the defense forces had a tendency to treat such discoveries as hostile, to which Megatron responded that if and when he was leader, he could make such decisions. When a [[The Fallen|mysterious relic]] was uncovered, Optimus disagreed with Megatron's order for it to be removed from the ground. Just as the two were about to launch into yet another argument, aliens previously encountered by Commander [[Starscream (Movie)|Starscream]] attacked Cybertron. Megatron blackmailed Optimus into moving the relic into his personal quarters by reminding the science leader that the science division would like to protect the only intact relic from harm. {{storylink|Defiance issue 1|Defiance #1}}

Optimus ordered his science teams to help the survivors on both sides, in the hopes of finding out who was responsible and why they attacked. While he went off to find Megatron, he ordered the others to continue searching for survivors while [[Arcee (Movie)|Arcee]] examined the alien remains. Optimus was shocked and appalled when Megatron ordered him to marshal his forces for war. Optimus objected, as his science division was not trained for combat, but Megatron retorted that the scientists should have known that aliens were after the AllSpark. He endured Megatron's insane fury when he accused the Protector of betraying that upon which their society was built. Later, Optimus called upon a meeting with his science division to ask them to stay by his side and continue on with their mission of peaceful research, as they were protectors, not soldiers. While the aerial-based Cybertronians followed Megatron into space, Optimus confided in [[Prowl (Movie)|Prowl]] and [[Jazz (Movie)|Jazz]] that Megatron sought to divide their planet, and he asked the former for help breaking into the High Protector's personal quarters. {{storylink|Defiance issue 2|Defiance #2}}

[[Image:Defiance3_OptimusPrime_battle.jpg|thumb|left|300px|Man...Prime ain't foolin' around.]]

After noting that Megatron had restored the artifact to pristine condition, Optimus had to leave the military leader's quarters just before he returned. Back at [[Burthov]], he came upon [[Ratchet (Movie)|Ratchet]], Arcee, and [[Elita-One (Movie)|Elita-One]] scanning the pieces of the other artifacts. Arcee then discovered that the pieces all contained the same symbol on them, and that the same symbol was on Optimus' head. Ratchet declared that the symbol was proof of the [[Dynasty of Primes]], and it indicated Optimus himself was a [[Dynasty of Primes|Prime]]. Ratchet and the other Autobots began to dub him "Optimus Prime", although a humble Optimus noted they did not know what it meant and for all they knew, he could just be from a line of record clerks. As they discussed the revelations, Prowl was forced by Megatron to arrest Optimus, but this turned out to be a trap to kill him. Optimus bested Starscream and blew up [[Metrotitan (ROTF)|Metrotitan]], while Megatron formed his new faction, the [[Decepticon]]s. {{storylink|Defiance issue 3|Defiance #3}} Optimus found Sentinel, Elita-One and [[Wheeljack (Movie)|Wheeljack]] under attack at the excavation site. He and [[Chromia (ROTF)|Chromia]] rescued them and escaped through a tunnel. Optimus also informed Sentinel of the marking on his head that proved he was right all along: he was a Prime too. {{storylink|Foundation issue 3|Foundation #3}}

[[Image:Ark Bridge Defiance4.jpg||thumb|300px|right|"Who ''are'' all you people?"]]
Retreating to Burthov with his fellow scientists and Prowl's security officers, Optimus was acknowledged as the leader of the group, with Prowl serving as his lieutenant. He and Prowl were discussing sites for a new base when Jazz informed them that Captain Ironhide of the [[Defense Force]] wanted to see Optimus. Learning of Megatron's new starship, the ''[[Nemesis (ROTF)|Nemesis]]'', Optimus Prime was convinced by his advisers that their side needed a ship of their own to prepare for any eventualities. The Autobots found themselves at an advantage when the ''Nemesis'' left Cybertron with the balance of the Decepticon forces, and Optimus himself took the fight to their enemies. However, years of bloody war devastated the planet, and Optimus saw no end in sight. {{storylink|Defiance issue 4|Defiance #4}}

Sentinel came up with a solution: a "torch" that would end the war without requiring the mass murder of the Decepticons. It required the AllSpark to activate, so Ironhide led the Autobots to Simfur Temple. {{storylink|Foundation issue 3|Foundation #3}} Elita-One successfully activated the torch, while Optimus fought off Megatron so she could deliver it to Sentinel. Sentinel boarded the [[Ark (DOTM)|Ark]] and arrived at Simfur, but to Optimus and Megatron's disbelief, Starscream blew the ship up. The Autobots fell back. With the Decepticons exhausted, Optimus ordered Wheeljack to pilot the second [[Ark (Movie)|Ark]] to take the AllSpark from Simfur. To Elita-One's concern, Optimus declared he would be going on a suicide mission to kill Megatron. {{storylink|Foundation issue 4|Foundation #4}}

Optimus, Ironhide and Elita-One made their way through Megatron's soldiers guarding his [[Lord High Protector citadel|citadel]]. Optimus demanded Megatron face him, but the Decepticon leader responded by dropping the [[smelting pool]] on him. Ironhide pushed Optimus out of the way, but Optimus's face was heavily damaged. Optimus entered Megatron's chamber alone as Ironhide was attacked by Starscream and [[Shockwave (Movie)|Shockwave]]. Optimus found Megatron surrounded by hungry [[hatchling]]s, gloating that Optimus was too weak to do what was necessary to win the war. Wheeljack then messaged Optimus, asking if they would go forward with removing the AllSpark. Optimus responded affirmatively, and Chromia and Arcee removed the Cube, darkening the skies of Cybertron. Optimus escaped, leaving Megatron to fend off his ravenous hatchlings, and rescued Ironhide. Returning to oversee the AllSpark's transportation, Optimus recognized his relationship with Elita-One had been forever scarred, and observed he still had a long way to go to being a great leader. {{storylink|Transformers: Foundation|Foundation #1-4}}

[[Image:Optimusprimemovieprequel.jpg|left|200px|thumb|All Primes are required to have window boobs.]]

The AllSpark was successfully ejected into space at [[Tyger Pax]], where [[Bumblebee (Movie)|Bumblebee]] distracted Megatron. Prime and the Autobots were held up in [[Simfur]] during the launch. {{storylink|Movie Prequel issue 1|Movie Prequel #1}} As they prepared to leave Cybertron on board the ''[[Ark (Movie)|Ark]]'' to go after the AllSpark, Optimus Prime had some doubts about his decision, feeling that in buying them some time in the war, he had sentenced their world to death. [[Prowl (Movie)|Prowl]] disagreed, pointing out that had Megatron been able to claim the Cube, all those that opposed him would have been destroyed, and that Prime had turned death into a fighting chance for the Autobots. Bolstered by Prowl's words, Prime resolved to rebuild their shattered home once they retrieved the AllSpark. {{storylink|The Reign of Starscream issue 1|The Reign of Starscream #1}}

Bumblebee remembered Optimus Prime's orders that they must launch the AllSpark into space, for it was better to lose it to the depths of space than allow Lord Megatron to corrupt it with his evil. For wherever there is hope, there is life. {{storylink|Transformers: Beginnings (Movie)|Transformers: Beginnings}}

{{note|Transformers: Beginnings is a condensed, flash-animated retelling of the [[IDW Publishing|IDW]] [[Transformers: Movie Prequel |Movie Prequel]] that is detailed above this section.}}

===Titan Magazines ''Transformers'' movie comics===
[[Image:OptimusMovie_GeoffSenior.JPG|250px|thumb|Starting as he means to go on.]]

When war broke out, Optimus studied the entire history of intergalactic warfare from any datatrack he could find—he studied whole campaigns to desperate last stands, gaining a focused "playbook" of warfare strategy. He understands warfare on a practical and psychological level, and in desperate battles knows to show no mercy to opponents beyond a swift death. <ref>''Autobot VS Decepticon Smackdown! - Megatron V. Optimus Prime'', #4</ref>

Optimus was the focus of constant attacks by assassin drones and killed them all. In the aftermath of one, he witnessed a prophetic vision of the [[Mission City]] battle and realised the AllSpark's ejection could spread war to other planets—but too late to stop the launch... {{storylink|Transformers Comic issue 1|Prelude: Optimus Prime}}

{{note|The following event is unique to the Titan Magazines comics continuity, and thus does not occur anywhere else.}}

Almost immediately after the final battle against Megatron, Optimus Prime had to lead the Autobots against a horde of [[Zombie|zombie]] Decepticons. Despite having no idea how they could be stopped and having had his power drained by fighting Megatron, Optimus continued to fight the monsters rather than let them run amok. Ratchet worked out a solution just in time before Optimus fell.  {{storylink|Transformers Comic issue 7|Starscream's Militia}}

{{notetitantlg}}

In the alternate reality, Megatron defeated Optimus and took the AllSpark at [[Mission City]]. Prime's body was now partially frozen and in Decepticon hands. He was the last and only hope of the Earth resistance, and so Bumblebee and [[Mikaela Banes]] were not happy to find him offline.  {{storylink|Transformers Comic issue 9|Twilight's Last Gleaming, Part: 1}} 

She thawed him out while Bumblebee distracted Megatron, and the revived Prime challenged Megatron to a solo duel...  {{storylink|Transformers Comic issue 12|Twilight's Last Gleaming, Part: 4}} Unfortunately, Megatron's link to the AllSpark meant Optimus could not do any lasting damage and was never going to win. Luckily, Bumblebee and Mikaela saved the day, hitting the distracted Megatron with an old [[Sector Seven]] nanovirus. (Which means ''they'' were the last and only hope, but oh well.)  Despite Megatron dying as a result and the AllSpark being destroyed elsewhere, Prime could take no satisfaction in victory: this battle was won, but the war remained...  {{storylink|Transformers Comic issue 13|Twilight's Last Gleaming, Part: 5}}

[[Image:Optimus_Titan12.JPG|left|250px|thumb|"Megatron's face must be cut off...no MATTER THE COST!"]]

He became resigned to the fact that Humanity, battered by Decepticon occupation, would view both Autobot and Decepticon as hostile invaders. When [[NATO]] was manipulated into attacking the Autobots, Optimus refused to allow his men to return fire, and after the crisis passed, he was sure that [[Starscream (Movie)|the Decepticons' unknown new commander]] was up to something bigger. Optimus also placed the last AllSpark fragment in the care of Ratchet, though he was worried exposure to Megatron might have corrupted it.  {{storylink|Transformers Comic issue 14|Aftermath Part 1}}  {{storylink|Transformers Comic issue 15|Aftermath Part 2}} He was ''not'' happy when Ratchet "took care" of the fragment by bringing [[Jazz (Movie)|Jazz]] back with it, who was left corrupted and amoral by it.  {{storylink|Transformers Comic issue 16|Dark Spark}}

Optimus Prime soon worked out that while the AllSpark's transformation of Earth had been halted, the damage had been done: the organic Earth and the technological transformation were now fighting for supremacy, killing the planet in the process. He called in a specialist team to investigate and limit the damage, while working with [[President of the United States|President Allen]]. In secret, he organised for [[Nucleon]] to be retrieved from the dead Cybertron and brought to Earth, as there was a long shot it could save the planet. He didn't tell the humans out of concern that if they knew about the plan and it failed, their hopes would be raised and dashed.  {{storylink|Transformers Comic issue 17|Return to Cybertron: Part 1}} It was bad enough that Nucleon was so unstable it could turn destructive...  {{storylink|Transformers Comic issue 18|Return to Cybertron: Part 2}}

When the team on Cybertron sent a distress signal and reported [[Stockade (Movie)|Stockade's]] Decepticons had captured the Nucleon, Optimus led the entirety of the Earth-bound Autobots (save Camshaft's team) to Cybertron as back-up. He was then surprised to see Cybertron coming to ''them'', looking [[Unicron|a lot meaner these days]]. {{storylink|Transformers Comic issue 19|Return to Cybertron: Part 3}} The planet's possessor, Unicron, shot down the Straxus and the Autobots survived only by evacuating it in time in [[protoform]] modes. 

Optimus landed next to Stockade's old equipment and, after being filled in by [[Arcee (Movie)|Arcee]], he effortlessly formed an alliance with Stockade against Unicron. His plan was to drain the Nucleon away so Unicron couldn't use it as a power source, while the bulk of the Transformers provided a distraction, which turned out to be going underground and shooting up Unicron's body. The plan worked, Nucleon was secured for Earth, and Optimus extended an offer for Stockade to join them on Earth whenever he wished. Optimus was left optimistic that Autobots and Decepticons had come together in a common cause.  {{storylink|Transformers Comic issue 20|Return to Cybertron: Part 4}}

On returning to Earth, he found the Decepticons had seized the Autobot base and six hundred square miles around it; he made the decision to withdraw to [[Washington, D.C.]], knowing that this meant leaving Mikaela in Decepticon hands. Upon landing at an air base, the Decepticon-controlled President Allen lured him into a trap, and he found himself fighting Jazz, now a Decepticon hired gun. Optimus lured him away from humans and prepared to engage him, but when a second assassin named [[Kullt]] turned up, Jazz gunned it down out of annoyance. Optimus had viewed Jazz as a lost cause but now stated there was still some Autobot in him: he ''could'' have let Kullt do the work for him and then killed him, but he saved Prime instead.

The battle made it clear to Optimus that Allen was under Decepticon mental control.  {{storylink|Transformers Comic issue 21|Hard Target}}

[[Image:Optimus Titan22.JPG|200px|thumb|Freedom is not dispensed here, sentient fools, only DEATH!]]

As he'd promised Bumblebee, Optimus took the Autobots to get Mikaela back; he himself went first, launching himself in [[Protoform|protoform]] mode to land in Savannah like a bomb and tearing his way through [[Swindle (Movie)|drone hordes]]. He was quickly gunned down by aerial units and about to be killed by Starscream, but this whole flashy attack had been a diversion—allowing other Autobots a chance to hit the distracted air forces and nab Mikaela. After the battle, Optimus remarked Starscream was no Megatron.  {{storylink|Transformers Comic issue 22|The Decepticon Who Haunted Himself}}

Optimus seemed to quickly bond with [[Seward|General Seward]], his military liaison at Andrews Air Base, but that didn't help when the mind-controlled President Allen had the government order the Autobots out of America. {{storylink|Transformers Comic issue 23|Revolution Part One}} However, Prime had anticipated this. Almost two weeks before, he'd had Ironhide task [[Tom Banachek]] to identify all the Decepticon puppets for him. With Allen making the expected move, he dispatched Ironhide and Bumblebee to set things up so that the following day, when the Autobots all departed, Allen would try to nuke them out of the sky and be fooled by a decoy ship into thinking he'd killed them. {{storylink|Transformers Comic issue 25|Revolution Part Three}} 

To protect the Earth while they were undercover on Cybertron, Optimus had made a deal with Stockade to start a [[Decepticon Civil War]]. Optimus didn't trust Stockade to not renege on the deal and just take control of Earth for himself, {{storylink|Transformers Comic issue 24|Revolution Part Two}} but he ensured the Decepticons were set up for the Autobot's final strike: forcibly teleporting all of the enemy to Cybertron via Unicron's leftover teleportational engines, then stranding Cybertron in a remote solar system. Optimus led the troops to Earth and witnessed Megatron's return from the dead... only to ''thwack'' him flying. The next minute, both Megatron ''and'' Stockade (why wait for him to renege?) were teleported away, along with their forces. 

This left the Autobots stranded on Earth and with a lot of clean-up to do. But Optimus had ''finally'' brought about the end of the war... {{storylink|Transformers Comic issue 25|Revolution Part Three}}

===''Ghosts of Yesterday''===
Optimus Prime led the search for the AllSpark in the ''[[Ark (Movie)|Ark]]'', a transport vessel. When they came across an abandoned solar system, they located [[Ghost 1|a vessel]] of strangely Cybertronian design, seemingly of Decepticon make. When the vessel fled to the surface of a planet, Prime dispatched Bumblebee to investigate while he and the other Autobots battled Decepticons from the ''[[Nemesis (Movie)|Nemesis]]''. Prime managed to defeat [[Blackout (Movie)|Blackout]], [[Scorponok (Movie)|Scorponok]], and [[Frenzy (Movie)|Frenzy]] all on his own. After losing touch with Bumblebee, Prime went down to locate him on the planet, where they were attacked by [[Starscream (Movie)|Starscream]] and the alien ship. They fell into a cavern network, where they were further attacked by [[Worm-thing|indigenous worms]].

During their flight from the creatures, Optimus Prime and Bumblebee came across the alien vessel. Prime realized that they were trying to surrender, so the Autobots communicated with its crew. Optimus explained that they came in peace, "freedom is the right of all sentient beings," Starscream tricks everyone, and so on. However, the creatures, who called themselves "[[Human|humans]]", explained that they held Megatron, whom they called the Ice Man, on their home world, [[Earth]]. Realizing the destruction Megatron would wreak upon the humans if he escaped, and that the humans would be unable to defend themselves effectively, Prime vowed to see them return to their world to warn it. Prime was able to blast an opening in the cavern, and the group escaped. As they returned to the ''Ark'', Prime began to speculate that the AllSpark was what drew Megatron to Earth.

In the ensuing battle with the Decepticons, Prime was in the difficult position of fighting Starscream and protecting the human ship. His distractions allowed Bonecrusher to spear him with his tail. The difficult state nearly gave Starscream the chance to kill him, but the humans saved Prime's life by damaging Starscream, who destroyed them. Optimus Prime was inspired by their courage and sacrifice, and resolved to locate Earth before the Decepticons did—and hopefully before Megatron came back online. {{storylink|Transformers: Ghosts of Yesterday|Ghosts of Yesterday}}

{{bigquote|A necessary sacrifice to bring peace to this planet. We cannot let the humans pay for our mistakes.|Optimus Prime on sacrificing his life to destroy the [[AllSpark]]}}

[[Image:Movie OptimusPrime protoform.jpg|right|220px|thumb|Having overenergized the previous night, Prime woke up abandoned in a field, with his wallet and clothes stolen.]]
The leader of the Autobots, Optimus Prime, came to Earth shortly after [[Bumblebee (Movie)|Bumblebee]] sent his comrades a beacon. Upon atmospheric reentry, Prime managed to land outside of [[Tranquility]]'s inhabited areas. While Sam and Mikaela watched, Optimus transformed and left his landing place. From atop a hill, he quickly scanned the form of an Earth truck, thus configuring his body to transform into it. Prime, [[Jazz (Movie)|Jazz]], [[Ratchet (Movie)|Ratchet]], and [[Ironhide (Movie)|Ironhide]] met up with Bumblebee and his human friends, [[Sam Witwicky]] and [[Mikaela Banes]] in an alley. Prime assumed his robotic form before the stunned humans. After confirming Sam's identity, Prime introduced himself and his team. When Sam asked how they could speak English, Prime told them that they scanned Earth's languages on the world wide web. When Mikaela asked of the Autobots' intentions, Prime explained the search for the AllSpark, the betrayal of Megatron, and why Sam was important to their search.

[[Image:Movie PrimeSam parentsfreakout.jpg|left|300px|thumb|Optimus Prime will watch you fornicate. And there is nothing you can do about it.]]
Glasses that belonged to Sam's ancestor, [[Archibald Witwicky|Captain Archibald Witwicky]], contained the location of the AllSpark encoded across its lenses, so Optimus Prime ordered his troops to wait outside Sam's house while Sam and Mikaela searched inside for the glasses.  Much to Sam's exasperation, Optimus Prime, in his impatience, clumsily ruined his parents' garden using some very expressive apologies, and the Autobots' heavy footsteps convinced them there was an earthquake. Prime's attempts to hide, such as having the Autobots transform into vehicle mode right in the backyard, were also less than satisfactory. Ultimately, Sam came so close to a panic attack that Prime was forced to order the Autobots to fall back. As Prime lectured his team on their supposed inability to remain quiet, Ratchet got himself shocked by walking into some powerlines, causing further problems. When [[Ron Witwicky|the]] [[Judy Witwicky|parents]] came to investigate, Prime's attempt to avoid discovery caused the house to shake, though this was to their benefit, as the father assumed that the damage to the yard was the result of an earthquake. Ironhide suggested that they kill the parents, but Optimus scolded his old friend. Despite all this, their presence remained undetected until [[Sector Seven]] arrived (in a convoy of GMC Yukons) and abducted Sam, Mikaela, and Sam's parents.

[[Image:Movie Optimus Prime S7 mad.JPG|right|300px|thumb|Get out of the car...what's left of it anyway!]]
Optimus Prime sent the Autobots in pursuit of the SUV that contained Sam, Mikaela, and Sector Seven's director, [[Seymour Simmons|Agent Simmons]]. Prime intercepted the vehicle carrying their young human friends, ripping the roof of the vehicle off, with the other Autobots disarming the agents, and made it perfectly clear to Simmons how pissed off he was at him for trying to apprehend the two children, regarding this as a bad move on Simmons' behalf. Optimus then ordered his comrades to relieve the agents of their weapons, and attempted to interrogate Simmons. The agents' lack of surprise at their appearance indicated that they had seen Cybertronians before, but Simmons refused to reveal any information. With a Sector Seven backup team en route, Prime ordered the Autobots to scatter, while he took Sam and Mikaela. While hiding under a bridge, Mikaela and Sam slipped and fell off Prime's shoulder. Bumblebee managed to catch them before impact, but was captured, and Sam and Mikaela recaptured, by the organization after their retreat. Now in possession of the glasses which could tell him the location of the AllSpark, Optimus regretfully left Bumblebee in Sector Seven's hands, knowing that if they went after him, they would have to use deadly force. 

After regrouping the next day, Prime used the glasses to locate the AllSpark. Jazz again raised objections to leaving Bumblebee behind, but Prime remained firm in his belief of not harming the humans. Ironhide seemed okay with using deadly force, stating the humans were too violent, but Prime countered that when their time had come, the Cybertronians had been [[Cybertronian Civil Wars|little different]]. Going on to explain the potential he saw in the humans, as well as reminding them that "freedom is the right of all sentient beings", Prime revealed to the Autobots his real plan for the AllSpark: if they could not defeat the Decepticons, Prime intended to merge the Cube with his [[Spark|spark]]. Though this would destroy the AllSpark, Ratchet cautioned Prime against this, as it would also kill him. Prime believed that this was acceptable, vowing not to let another race suffer the mistakes of the Transformers. The glasses placed the AllSpark at [[Hoover Dam]] where, luckily, Bumblebee and the young humans were taken.  

[[Image:Movie2007 Prime sword.jpg|left|300px|thumb|Swiss army Prime.]]
Optimus Prime's team met up with Sector Seven, Bumblebee, Sam, and Mikaela en route, who had planned to hide the AllSpark in nearby [[Mission City]]. While on the highway, he was attacked by [[Bonecrusher (Movie)|Bonecrusher]], who managed to tackle Optimus and drag him over the edge of a freeway overpass. During the battle, Optimus struck the rage-filled Transformer so hard his [[Optic|optic]] popped out. As the Decepticon swung his claw wildly, Optimus drew his sword from his right arm and sliced off one of Bonecrusher's arms, before brutally finishing off his enemy by [[Decapitation|driving the blade through]] Bonecrusher's neck, severing his head.

Optimus arrived at Mission City just in time to observe Megatron discarding the remains of Jazz, and challenged him. Millennia in the ice had done nothing to lessen Megatron's hatred of his brother, and he launched himself in jet mode at the Autobot leader. Optimus leaped and grabbed hold of the wings, which was a really bad idea, as Megatron drove himself and Prime through an office block. As they flew out of the building onto the street below, Megatron transformed and leapt on top of Prime, declaring the humans undeserving of life. Prime rejected his claims, saying that they deserved to choose for themselves. Megatron threw Prime across the street, declaring that if he wished to defend the humans, Prime could die with them. He then formed his [[Fusion cannon|fusion cannon]] from his forearms. The power up time allowed Prime to draw his [[Ion blaster|ion blaster]] and fire, hitting Megatron. The Decepticon used the momentum to spin around, then used the fusion cannon to blast Prime across the street into another building. Megatron then resumed the hunt for Sam and the AllSpark.

[[Image:Movie2007 Prime truck.jpg|right|300px|thumb|He knows he's a sexy truck.]]
Tracking Megatron to the deserted building, Prime barely managed to catch Sam after Megatron knocked him off the roof. Telling the boy to hold onto the Cube, Prime attempted to scale down the building, but Megatron jumped on Prime, causing them both to fall down hard onto the street below. Sam survived, however, and Optimus told the boy that if he could not defeat Megatron, Sam must put the AllSpark into his chest which would destroy it. As Sam sought cover, Optimus faced down Megatron, and informed him that, "At the end of this day, one shall stand, one shall fall". Unfortunately, Megatron, even after years of stasis, proved to be far too powerful for Prime to defeat alone. The unit led by Lennox and the Raptor squadron laid down suppressing fire as Megatron reached for the AllSpark, until Optimus finally took him down by sweeping his legs. Still, Megatron continued, crawling toward the cube. Believing he had lost, Optimus implored Sam to put the AllSpark into his chest. Sam instead thrust it into Megatron's chest, killing the Decepticon leader and destroying the AllSpark.  

[[Image:Movie2007 Prime AllSpark shard.jpg|left|300px|thumb|The Autobot [[Matrix of Leadership|Dorito of leadership]]]]
As Optimus watched his brother die, he regretfully said there was little other choice. He also told Sam he owed him a debt of gratitude for saving his life, but was then informed that Jazz had not survived (Jazz was flapping around disrespectfully like a ragdoll during this sequence). Prime briefly eulogized his comrade, then commented that they had gained new comrades in the humans, and was honored by their bravery. Bumblebee, who had finally regained his voice, requested permission to remain with Sam Witwicky, to which the young human eagerly agreed, and Optimus approved. He noticed a fragment of the AllSpark in Megatron's chest cavity and removed it, then permitted the humans to dispose of the Decepticon corpses by dumping them into the deepest part of the ocean.

[[Image:Movie Optimus ending.JPG|right|300px|thumb|[['Til all are one]]!]]
Though Megatron was killed and his Decepticons were defeated, the AllSpark was destroyed, leaving the Autobots unable to restore Cybertron. The Autobots elected to remain on Earth, and Prime sent a message into deep space to any surviving Autobots in the Galaxy to come to their new home on Earth, their long years of searching having finally having come to an end. As the other Autobots rested (and watched Sam and Mikaela make out on Bumblebee's hood) Optimus Prime looked to the sky, hoping his message had been heard. {{storylink|Transformers (film)|Transformers}}

When the AllSpark was destroyed, Optimus was ''bathed'' in its power and became a living receptacle: he could destroy or heal with the merest thought. He still remained dedicated to peace, and altered his exterior decorations to match the ones he bore as a young leader, before the beginning of the war. {{storylink|Optimus Prime (Movie)/toys#Voyager Class toys|First Strike Optimus Prime}}

When the war turned out to ''not'' be over though, and with more Decepticons appearing on Earth, he was forced to alter himself to be used for stealth missions—something he finds dishonourable but knows has to be done. He is now sensor transparent and silent. {{storylink|Optimus Prime (Movie)/toys#Leader Class toys|Nightwatch Optimus Prime}} In this form, he came under surprise attack by an equally stealth-modified Starscream, leader of the new Decepticons! {{storylink|Optimus Prime (Movie)/toys#Legends Class toys|Nightwatch Optimus Prime vs. Stealth Starscream}}

Once the Decepticons were beaten on Earth, Optimus was provided with intelligence by [[Sector Seven]] about Decepticon bases on Mars. After assuming new colors, he headed to the red planet. {{storylink|Optimus Prime (Movie)/toys#Fast Action Brawlers|Fire Blast Optimus Prime}}

===''Beast Wars Diorama Story''===
[[Image:BWDS 11.jpg|thumb|300px|]]
[[Beast Wars (event)|On Earth in the past and in another universe]], a contingent of [[Maximal]]s, led by [[Optimus Primal]], battled a group of [[Predacon (BW)|Predacons]] in a forest. {{storylink|Optimus Primal Chapter}}

Some time into the battle, a warp opened, bringing with it [[Jazz (Movie)|Jazz]], [[Ironhide (Movie)|Ironhide]], [[Starscream (Movie)|Starscream]], Optimus Prime, and [[Ratchet (Movie)|Ratchet]]. Optimus Prime made fast friends with [[Optimus Primal]]; they joined their forces and double-teamed the injured [[Starscream (Movie)|Starscream]], who had just taken a blast to the face from [[Tigatron]]. Starscream then joined the Predacons. The two Optimuses commemorated their accomplishment of teamwork by shaking hands. The Maximals and Ratchet looked up with approval. {{storylink|Tigatron Chapter}} [[Blackout (Movie)|Blackout]] later appeared and joined the Predacons. As the battled raged, the [[Megatron (Movie)|Megatron]] from Prime's universe came in through the warp. {{storylink|Gimlet Chapter}}

The Decepticon Megatron brought along [[Brawl (Movie)|Brawl]], and the two Megatrons combined their troops into a fearsome force against the Autobots and Maximals. Fortuantely for the Autobots and Maximals, [[Motorarm (BWII)|Motorarm]] arrived to assist. The two factions then took formation against each other with the intention of combining their energies to attack the opposing side. With [[Motorarm (BWII)|Motorarm]] leading the charge, the Maximals and the Autobots attacked first. {{storylink|Motorarm Chapter}}

===IDW ''Revenge of the Fallen'' comics===
[[Image:AllianceOptimusHoloDriver.jpg|right|250px|thumb|[[Peter Cullen|Optimus Prime]] driving Optimus Prime! Sheer awesomeness!]]

Following the battle of [[Mission City]], and the destruction of Megatron and the AllSpark, Optimus Prime was left to ferry the body of his first lieutenant [[Jazz (Movie)|Jazz]] out of the city in an abandoned trailer. Trusting [[William Lennox|Captain Lennox]] and his men, Prime asked the human soldiers to help the Autobots escape from the city, before [[Sector Seven]] and other untrustworthy humans could arrive. A month later, [[Seymour Simmons|Agent Simmons]] managed to convince Lennox and [[Robert Epps|Sergeant Epps]] to call upon the assistance of Optimus Prime and the Autobots to escort the Decepticon remains, thereby hopefully reactivating the Decepticon [[Wreckage (Movie)|Wreckage]] somehow.  {{storylink|Alliance issue 1|Alliance #1}}

Optimus, Ironhide, Ratchet and Bumblebee arrived at Sector Seven's Nevada desert base to escort to a naval base at [[California|San Diego, California]]. Optimus insisted on escorting Jazz's remains personally, and thanked Lennox for arranging a proper burial-at-sea for his fallen lieutenant. When he noticed the AllSpark shard seemingly reacting to the Decepticon bodies, he handed the fragment to [[Vine|Professor Vine]] for safekeeping until he returned. Shortly after leaving the base, Optimus had second thoughts about leaving the fragment in Sector Seven's possession, and ordered Bumblebee and Ironhide to turn around and retrieve the only remaining piece of the AllSpark. {{storylink|Alliance issue 2|Alliance #2}}

[[Image:Alliance3_OptimusPrime_Lennox.jpg|thumb|left|300px|"So erm, want to go back to my place?"<br/> "Prime, are you trying to get onto me?"<br/> "No dude, I just want to show you my collection of faces and heads!"]]

The convoy returned to the Sector Seven base after learning of Wreckage and Starscream's attacks. [[Salani]] retrieved the AllSpark shard and returned it to Optimus Prime, who felt the last piece of their heritage should stay with him. Weeks later, the Autobots and the soldiers with whom they served traveled aboard a [[United States Navy|US Navy]] carrier for Jazz's burial-at-sea and to observe the disposal of the Decepticons. Optimus deeply appreciated the humans' paying last respects to their fallen comrade, though he was  concerned that even the great depths of the [[Laurentian Abyss]] were not enough to keep the Decepticon bodies hidden. Below deck, Optimus and Lennox agreed to a formal [[NEST|alliance between the Autobots and humans]] as the first line of offense and defense against the Decepticons. During training on the island of [[Diego Garcia]], Optimus Prime reminded the Autobots that they must work together with the humans as a team, never forgetting that division was what caused the war on Cybertron in the first place. When they were alone, Optimus Prime and Major Lennox complimented each other's leadership and the dedication of their respective troops. When Lennox commented that it was because of the Autobots that he and his soldiers were alive today, Optimus refuted this, saying it was because of humans such as Lennox and Sam, and that the Autobots were only part of the problem. Soon, both [[NEST]] leaders learned that the Decepticons had returned to Earth. {{storylink|Alliance issue 3|Alliance #3}}

By November 2008, Sideswipe had arrived on Earth, but was recklessly pursuing the Decepticon Demolishor in [[South America]]. Optimus was chastised by Admiral Morshower for this "grey area" in the Autobot ranks, but the Autobot leader assured Morshower he would settle it. Human relations were so strained the exasperated Optimus decided to forcibly bring Sideswipe in to end his rampage; however, Ironhide requested he go calm his former student down. Optimus agreed, but made his position clear: if Sideswipe could not be negotiated with... he would be ''dealt'' with. Ironhide eventually was able to calm his student, but not before Demolishor was let loose upon human civilians, AND the authorities were attacking Cybertronians on sight. Luckily, Optimus and a strike team had already arrived and had the authorities stand down, and Sideswipe joined the Autobot ranks. {{storylink|Tales of the Fallen issue 2|Tales of the Fallen #2}}

[[Image:Alliance4_Prime_killingspree.jpg|thumb|300px|Freedom is the right of all '''non-Decepticon''' sentient beings.]]

NEST was deployed to [[San Francisco]], where the Decepticons [[Swindle (Movie)|Swindle]] and [[Jolt (Movie)|Dead End]] were wreaking havoc. Flushed out of hiding, the Decepticons managed to evade the other Autobots, but Optimus Prime quickly put down Dead End by ramming him head-on. When asked by Prime, he commented that he was fine, but he wasn't sure if Dead End was. On the way back to base, Lennox and Optimus Prime discussed Swindle's last words and were concerned that this was just the first wave of Decepticons coming to Earth, and that they were after [[Sam Witwicky]]. Optimus convinced Lennox that no matter what, it was Sam's destiny to become involved in this conflict, and they agreed to send Bumblebee back to the States to resume his role as the boy's guardian. Later, when Optimus observed the distrust for the Autobots held by Lennox's superiors, he suggested that they must work harder and that continued success would satisfy those above them. During the subsequent hunt for Decepticons around the world, Optimus Prime personally destroyed [[Jetstorm (Movie)|Jetstorm]], [[Dropkick]] and [[Incinerator (Movie)|Incinerator]]. As NEST's ranks grew, together they celebrated their victories and mourned those who made the ultimate sacrifice. One event brought joy and hope to the team: The arrival of Autobot refugees who were eager to protect their new homeworld. This joy was tempered by the fact more and more Decepticons were being sighted on Earth, and Optimus believed that there was some unknown that threatened their new home, their species and their alliance with the humans. {{storylink|Alliance issue 4|Alliance #4}}

===''The Veiled Threat''===
{{Note|The events of ''The Veiled Threat'' take place during [[IDW Publishing]]'s ''[[Transformers: Alliance|Alliance]]'' comic.}}

{{bigquote|I know Megatron. I know all of you. You would not have taken the AllSpark and left this world in peace. You would have subdued it and made slaves of its people. Even in the absence of the AllSpark, my conscience and that of my friends could not have allowed that.|Optimus Prime to [[Macerator]]}}

Optimus attended an initial [[NEST]] briefing about sightings of Starscream in [[Zambia]], and was placed in joint command with Lennox of a team to go there to investigate. He also advised some new Autobot arrivals about how best to fit in on Earth. In Zambia, they quickly tracked down three Decepticons, [[Payload (Movie)|Payload]], [[Macerator]] and [[Dropkick]] waiting at the Zambezi River. Optimus, Ironhide and Ratchet waded in to face their opponents, unaware that it was a trap — as they fought, they were dragged downriver towards Victoria Falls. Although the other two Autobots escaped the trap, Optimus was held fast by Macerator and plunged off the falls. While Macerator was caught mid-air by Starscream, Optimus managed to cling to an outcropping. He was rescued by the other Autobots present, utilizing [[Beachbreak]]'s tow line. Enraged by the rescue, Starscream killed Beachbreak, something Optimus regarded as a result of his own failure to lead. The team tracked Payload, Macerator and Dropkick downriver to the Kariba dam, where Optimus rammed two of the Decepticons and then fought with Macerator at length. He eventually triumphed, decapitating the Decepticon. As Dropkick retreated, Optimus stopped Ironhide from firing as he might have hit some of the humans nearby. They instead went to look for Payload, who had been swept away by raging waters from the dam emergency release.

Back at [[Diego Garcia]], two more Decepticon contacts were made in [[Australia]] and [[Peru]]. Optimus opted to lead the team checking Australia. After exploring the Outback for a number of days, the team discussed whether the Decepticons might be hunting for energy to resurrect Megatron, but Optimus doubted there was an energy source on the planet that could do so. They eventually encountered [[Kickback (ROTF)|Kickback]], [[Trample]] and [[Tread]], three [[Constructicon (ROTF)|Constructicon]]s mining for minerals. Optimus found Kickback's sonic charge weapon to be a challenge, but with some help from Lennox, killed the Decepticon.

After they returned to base, Optimus's input into the conversation on how the Decepticons might revive Megatron was for the most part unhelpful. The subsequent appearance of [[Jolt (Movie)|Deadend]] and [[Swindle (Movie)|Swindle]] in [[Rome]] led the Autobots to take another trip, but Optimus found Rome's narrow streets frustrating as he was unable to navigate them in his truck form. After [[Knock Out (ROTF)|Knockout]] dealt to the two Decepticons, a furious Starscream challenged Optimus to one-on-one combat in the nearby Colosseum. Naturally it was a trap — Starscream had allied himself with a human, [[Bruno Carrera]], and together they trapped Optimus in a pit and set Barricade on him. With the help of four humans, Optimus broke free, threw Barricade into the pit and sealed him there. He then had only to show his face outside to where Starscream was fighting Ironhide, Ratchet and [[Salvage (Movie)|Salvage]], and the would-be Decepticon leader fled. {{storylink|Transformers: The Veiled Threat|The Veiled Threat}}

Since coming to Earth, Optimus has had to strive daily to gain credibility with the human powers-that-be. {{storylink|Transformers Comic issue 2.5|Reversal of Fortune}}

Even Optimus doesn't believe [[Skids (ROTF)|Skids]] and [[Mudflap (ROTF)|Mudflap's]] stories anymore! When those same twins arrived, Optimus was absent on a 'need to know' mission {{storylink|Transformers Comic issue 2.3|Learning Curve}} in [[Australia]] with [[Arcee (Movie)|Arcee]]. When [[Sideways (ROTF)|Sideways]] landed on the continent, the two Autobots interrupted their mission to bring the bot in. It proved far more difficult than you'd expect, with the Decepticon able to outdistance them in the long run and better suited to the terrain. Optimus was knocked offroad when Sideways blasted him with exhaust, and Arcee reported her alt mode was too out of its comfort zone to keep up... which gave Optimus an idea. 

That idea was to take ''away'' the terrain, blasting Sideways off the road and into the grass with projectile weaponry. Violence works!

Optimus took the prisoner to Diego Garcia, and on arrival was greeted with the sight of the twins brawling on the runway. He bawled them out over improper conduct, but before he could go further [[Scorponok (Movie)|Scorponok]] made an attack. Taking fire, Optimus began barking out orders... only to be tripped up by Skids. Once he was up, Scorponok and Sideways had both done a runner. Knowing that the enemy could ''not'' have got this close without NEST security being compromised, Optimus was convinced by [[Sideswipe (Movie)|Sideswipe's]] argument that the twins had turned traitor and had them taken away for questions. {{storylink|Transformers Comic issue 2.5|Reversal of Fortune}}

When the twins were sprung by Decepticons, Prime agreed with [[Theodore Galloway]] that the Autobots would make finding the twins a number one priority. However, Optimus was left suspicious when a [[Soundwave (ROTF)|mysterious "friend"]] tipped the Autobots off about the twins. {{storylink|Transformers Comic issue 2.6|Outlaw Blues}} Soon, it came out that the twins were being framed and by tracking the two, Optimus and his men found out about a Decepticon base near [[Mars (planet)|Mars]].

[[Image:ROTF-DemolishorPrime.jpg|thumb|right|250px|With the Legends and Voyager toys, this scene is ''just'' possible.]]
After the events in [[Mission City]] two years ago, Optimus Prime and the Autobots became part of a Transformer/human military group called [[NEST]], which hunted down the remaining Decepticons across the world.  When [[Demolishor (ROTF)|Demolishor]] and [[Sideways (ROTF)|Sideways]] were detected in [[Shanghai]], NEST was deployed there, including the Autobots [[Sideswipe (Movie)|Sideswipe]], [[Ironhide (Movie)|Ironhide]], [[Arcee (Movie)|Arcee]], [[Skids (ROTF)|Skids]] and [[Mudflap (ROTF)|Mudflap]].  Once Demolishor made himself known by transforming into robot mode and crushing dozens of cars along the highway, [[Robert Epps|Sergeant Epps]] radioed an overhead C-17 to release the Autobot leader. Optimus Prime parachuted out of a NEST cargo plane and landed in vehicle mode. He leapt off a bridge onto the Decepticon's head as he plowed through it. When the massive Constructicon refused his order to pull over, Optimus unleashed several blasts of his [[ion blaster]] into Demolishor's head. These shots, coupled with Ironhide destroying his tires, sent the titan crashing to the ground and into a warehouse. As he and Ironhide approached the dying Decepticon, Optimus asked if he had any last words. With his dying breath, the Constructicon stated that [[The Fallen]] would rise again. Optimus responded in the negative and unceremoniously executed him.

Returning to [[Diego Garcia]], Prime entered a briefing with [[Theodore Galloway]], the National Security Adviser who had been appointed liaison by the [[President of the United States|President]], and [[Morshower|General Morshower]], the Chairman of the Joint Chiefs of Staff, who was watching by satellite feed. Prime relayed the warning of The Fallen to them, but Galloway made no effort to conceal his hostility toward the Autobots. He noted that while they had given them intelligence and the sole remaining AllSpark fragment, Galloway took issue with their refusal to share weapons technology and their continued sending of transmissions into space. Prime told Galloway that the Autobots were aware of humanity's history of warfare, and Morshower said that all the transmissions had been vetted by NEST officers. Galloway also pointed out that despite Megatron's death and burial in the Laurentian Abyss and the destruction of the AllSpark, the Decepticons had not left Earth as Optimus had hoped, leading him to conclude that the Autobots were the ones who the Decepticons were after. When asked if the Autobots would leave Earth peacefully if told to, Optimus replied that they would honor their request, but warned Galloway to consider what would happen if the Autobots left but the Decepticons did not.

Unknown to Prime, the Decepticon [[Soundwave (ROTF)|Soundwave]] had been monitoring transmissions and spied on the briefing. Dispatching [[Ravage (ROTF)|Ravage]] to the island, he had his agent steal the remaining AllSpark fragment, killing several soldiers in the process. The incident left the Autobots with rather chilly relations with the United States. Seeking outside help, Optimus dispatched Bumblebee to retrieve Sam Witwicky from college in an effort to secure his testimony on the Autobots' behalf. Meeting Sam at an abandoned cemetery near his college, Optimus explained the situation. Sam was not receptive; in fact, he was quite hostile, saying that he had just started college and was trying to have a normal life. Knowing that fate often called at inconvenient times, Optimus impressed upon Sam the importance of what was going on, but Sam reiterated that the Cybertronian War was not his, and that they didn't need him. Optimus relayed his fear that it soon would be, and silently said that they needed him more than he realized.

[[Image:ROTFPrimevsMegsandScreamer.jpg|thumb|left|250px|Stick em' up!]]
Prime's fear soon came to pass, but in the last way he could imagine: the Decepticons had used the AllSpark shard to resurrect Megatron, who had learned that the knowledge of the AllSpark had been passed to Sam by a fragment Sam had touched, and soon captured him, Mikaela, and Sam's college roommate [[Leo Spitz]]. Heading to rescue the three humans, Optimus and Bumblebee ambushed the Decepticons in the [[Broadwater Metal Works|abandoned industrial complex]] where the teens were being held, just as [[Scalpel (ROTF)|Scalpel]] was about to perform fatal neurosurgery on Sam. Knocking Megatron and [[Starscream (Movie)|Starscream]] out of the building, Optimus managed to whisk Sam away from the plant. Optimus made it as far as the nearby forest when Megatron arrived. Going one-on-one with the Decepticon leader, Prime managed to hold his own, all the while trash-talking Megatron. Megatron then called for Starscream and [[Grindor (ROTF)|Grindor]], who quickly arrived. Prime was forced to run interference between Megatron and Starscream, who pursued Sam. 

[[Image:ROTF Optimus vs Grindor.jpg|thumb|right||250px|''Frenzy is red,''<br>'' Rumble is blue,''<br>''this poem doesn't rhyme,''<br>''NOW GIVE ME YOUR FACE !''<br>]]
As the battle raged, Megatron told Prime that the boy was the key to finding another energon source, then shattered his [[mouthplate]] and sent him flying back with a point blank shot from his [[fusion cannon]]. Megatron asked if the boy's life was greater than the future of their race, but Prime knew that he would never stop with a single life. Declaring that he'd take them all on, Optimus Prime unsheathed his [[Dual Energon Swords]] and fought a three-on-one fight against the Decepticons. Surprisingly, not only did he manage to hold his own, he was actually winning, managing to stab Megatron multiple times, slice off Starscream's arm and use it as a club, and rip apart Grindor's head. However, Megatron managed to stab his own sword through Optimus Prime's chest, following with a point blank shot through his injured back. Critically injured, Optimus implored the still-observing Sam to run. Although the rest of the Autobots soon arrived and drove off Megatron and Starscream, Optimus Prime was [[The_many_deaths_of_Optimus_Prime|dead]].

[[Image:ROTF Optimus death.jpg|thumb|left|250px|"You're so weak!"<br>"Then why have I spent this whole fight kicking your a—"*BOOM*]]
Soon after, The Fallen made his presence known and demanded Sam Witwicky be turned over to him or the world would be destroyed. Galloway used this as a reason to shut down NEST and ordered the Autobots returned to Diego Garcia under guard, along with Prime's corpse (which Galloway callously denounced as a piece of scrap metal). Fortunately, Bumblebee, and [[Skids (ROTF)|the]] [[Mudflap (ROTF)|Twins]] managed to spirit Sam, Mikaela, and Leo away before The Fallen made his announcement. With help from their former enemy Seymour Simmons and the Decepticon-turned-Autobot [[Wheelie (ROTF)|Wheelie]], the group discovered that Sam's mind contained the Language of the Primes, to which group The Fallen had once belonged. The human/Autobot group managed to locate the Seeker [[Jetfire (ROTF)|Jetfire]], who told them of how the [[Dynasty of Primes]] forged a [[Star Harvester]] to use a star's energy to replenish the AllSpark, and the [[Matrix of Leadership]], needed to activate the harvester, until they were betrayed by The Fallen, who tried to harvest [[Sun|Sol]] in defiance of the Primes' rule of the sanctity of life. Sam hit upon the idea to use the Matrix to restore Optimus to life, similar to how the Decepticons had used the AllSpark fragment to resurrect Megatron. Having been teleported to [[Egypt]] by Jetfire, the group managed to relay the information to Major Lennox and Sergeant Epps, who faked engine trouble over Petra, where the [[Tomb of the Primes]] was located. Unfortunately, the Matrix had turned to dust in the thousands of years since its entombment, but Sam still believed that it could be used to revive Optimus. 

[[Image:ROTF movie Powered-Up Optimus Prime.jpg|thumb|right|250px|I'm bringing sexy back.]]
However, the Decepticons were still looking for the Harvester and the Matrix needed to activate it. Sam was technically killed in the [[Operation: Firestorm|battle]], during which he communed with the six Primes from the tomb, who restored the Matrix. Jamming it in the fallen Autobot's chest, Sam used the Matrix to restore Optimus Prime to life. Unfortunately, The Fallen soon arrived. He stole the Matrix, and stomped on Optimus, sending him back to the ground. Having been fatally injured by [[Scorponok (Movie)|Scorponok]], Jetfire offered his parts to Optimus, as only a Prime could defeat The Fallen, and snuffed out his own spark. After Ratchet and [[Jolt (ROTF)|Jolt]] finished attaching Jetfire's wings and thrusters to Prime's body, Optimus hurried to the [[Great Pyramid of Giza]], which had been constructed around the harvester, and damaged the machine before it could destroy Earth's sun. 

[[Image:TheFallen-ROTFfacegotten.jpg|thumb|left|250px|Your face is insufficient. GIVE ME YOUR SPARK!]]
Optimus Prime then faced Megatron and the Fallen on the ground. This against the odds battle went far better for Optimus, as he used Megatron's own fusion cannon to shoot off half his face and his afterburners to send him through some ruins. Optimus then battled the Fallen, using his Energon Sword to slice through his face. The Fallen countered by ripping off his left wing and striking him with it, but Optimus managed to grab the Fallen's own spear and impale him with it. Telling the traitorous Prime he had picked the wrong planet, Optimus used the spear to rip off The Fallen's face plate. As The Fallen tried to flee, Optimus Prime punched through his abdomen and crushed his spark core, killing The Fallen and forcing Megatron and Starscream to retreat.

[[Image:ROTF Optimus Sam ship.JPG|thumb|right|250px|"So why did you want his face?"<br>"Okay, I'll tell you."*cuts to credits*]]
On the return voyage home, Optimus thanked Sam for saving his life, as the boy thanked the Autobot leader for believing in him. Following this, Optimus Prime sent another transmission into space, detailing recent events so that the pasts of both races would be remembered, and also declaring that Humanity and the Autobots would face the future together. {{storylink|Transformers: Revenge of the Fallen (film)|Revenge of the Fallen}}

===Titan Magazines post-''Revenge of the Fallen'' comics===
Following the later Fallen incident, Optimus continued operations against the Decepticons. [[Jolt (ROTF)|Jolt's]] over-enthusiasm began to muck that up, causing damage and getting NEST into trouble, despite Optimus' attempts to point this out to him. Optimus had to confine him to base. {{storylink|Transformers Comic issue 2.9|Culture Shock}} 

[[Image:Titan10_Optimusgetsout.jpg|thumb|right|250px|Never had a human face before.  GIVE ME IT ANYWAY!]]

Soon after that, he was drawn out into a trap by [[Trophy White]] and the [[Free Men]], who wanted to take his head as a trophy. Optimus worked out their plan and allowed himself to be captured by the deranged hunter, in order to keep the fight away from civilians. He pretended to be securely chained down and listened to White's sociopathic ravings, before (at the moment he considered funniest) breaking free and taking White prisoner. Shockingly, he found keeping the severed heads of animals as trophies to be ''bad'', and destroyed Trophy's trophies. {{storylink|Transformers Comic issue 2.10| Bring Me the Head of Optimus Prime}}

When there was a Decepticon breakout in [[South Africa]], Optimus ordered his men to let the prisoners flee: a battle outside [[World Cup|a major sports event]] would cause unacceptable civilian casualties. {{storylink|Transformers Comic issue 2.13|Inside Out!}} This led to a major collapse in Autobot popularity, and open battles with Decepticons in cities were just risking further alienation. In response, Prime created of a secret covert unit (even under NEST's radar) that would monitor the Decepticons, wait for windows of opportunity out of the public eye, and then hit hard and fast. While this worked, Optimus was left disquieted: the tactics he was using were too akin to the Decepticons, and a fine line was being walked. {{storylink|Transformers Comic issue 2.18|Shadow War}}

The Decepticon base was soon tracked to [[Russia]] and Optimus led a strike-team in. Unknown to him, [[Wheelie (ROTF)|Wheelie]] had sold them all out to Bludgeon and the team was ambushed, getting killed one by one... {{storylink|Transformers Comic issue 2.20|Divided Loyalties}} but luckily Megatron arrived to beat up Bludgeon for running a rival faction, and he flew away again after leaving an ominous threat to Optimus. So Prime didn't need to do any work saving his team or stopping Bludgeon at all! The end! {{storylink|Transformers Comic issue 2.21|A Short, Sharp Lesson!}}

===Cyber Missions===

[[Image:CyberMissions1 Optimus.jpg|right|thumb|250px|]]
Optimus Prime recorded some information on the Autobot-Decepticon war for preservation in [[Vector Sigma]]. Bumblebee and Ironhide were reviewing it when [[Bludgeon (ROTF)|Bludgeon]] and [[Soundwave (ROTF)|Soundwave]] launched their attack. {{storylink|Cyber Missions 1}} The next morning, Optimus had been informed of the attack and Soundwave's capture, and he ordered Ironhide to wait for reinforcements to assist in pursuing Bludgeon. Bludgeon made that difficult for Ironhide. {{storylink|Cyber Missions 2}} Later, Optimus contacted Ratchet to inform him that [[Lockdown (ROTF)|Lockdown]] was causing chaos in [[Mission City]], and he reminded the Autobot medic to be careful. {{storylink|Cyber Missions 3}} 

He and Sideswipe tracked Megatron to a disused factory, only to lose the scent.  Megatron, having cloaked his spark signature, jumped out of hiding to attack them, and Optimus used his swords to attack the Decepticon.  An appeal for Megatron to surrender was answered by a blast from Megatron's cannon bringing the roof down on the two Autobots, and the Decepticon escaped. Optimus promised that Megatron would no longer be able to hide. {{storylink|Cyber Missions 4}}

When Ironhide went missing after the incident with Bludgeon, Optimus searched for him, and Bumblebee revealed he was last near a cave with a load of [[Energon]]. That same cave happened to be where [[Mindwipe (ROTF)|Mindwipe]] was hiding. As Optimus went to rescue his friend, Mindwipe tried to hypnotize the Autobot leader, but Optimus was able to resist the hypnosis and defeat Mindwipe, leaving a confused Ironhide to wonder what was going on. {{storylink|Cyber Missions 5}}

Reports of [[Smolder]] attacking a building in [[Scramble City (city)|Scramble City]] resulted in Optimus dispatching Bumblebee and Ratchet to investigate. He filled them in on the situation en route. {{storylink|Cyber Missions 9}} During another mission, Optimus warned Sideswipe and Ratchet that they were being tracked, moments before the pair were attacked by [[Starscream (Movie)|Starscream]] and Mindwipe. {{storylink|Cyber Missions 10}}

Bumblebee reported to Optimus that he'd managed to pinpoint the location where Megatron and Starscream were meeting, leading Optimus to confront the two Decepticons in an Arctic region. When Megatron expressed surprise that he'd come to fight them without backup, Optimus assured him that the Autobots were never far from their leader's side. While Starscream went to attack the others, Optimus and Megatron continued to fight, with Optimus emerging the eventual victor. As Megatron tried to goad him into finishing the fight, Optimus announced that the Autobots protected all sentient life, and that included the Decepticons. He subsequently allowed Megatron to flee. {{storylink|Cyber Missions 12}}

{{quote|By showing even one such as him the power of mercy, Megatron might realize that we'll never give up, no matter the cost.|Optimus Prime|"Cyber Missions 12"}}

Prime set up an elaborate trap involving a hologram of Soundwave to lure the Decepticons to a spot in the wilderness. The ploy worked, and Optimus attacked Megatron while his men attacked Megatron's troops. At one point during the battle, Megatron threw a train car at him, and he simply somersaulted along its length. Though Megatron boasted that the Decepticons would win through sheer determination, Optimus knocked him to the ground and gave a speech about building alliances, which was the cue for the [[human]]s to turn up in force and surround the Decepticons. Optimus informed Megatron that he could either leave the planet peacefully or be destroyed. Once the rest of the Decepticons fled, Megatron delivered a final threat before taking off. Prime celebrated with another speech, before admiring the huge Autobot [[insignia]] Bumblebee had stomped into the ground. {{storylink|Decepticons Attack}}

===Transformers Annual 2011===
An alert of Decepticon activity in [[Tokyo]] sent Optimus, Ironhide, Ratchet and Sideswipe to investigate. He intervened in Sideswipe and Barricade's battle to lift the Decepticon into the air, only to find himself under attack by Grindor. Ordering Sideswipe and Ratchet to cover him, Optimus scaled the side of a nearby office block so he could punch the helicopter out of the air. Standing over the two Decepticons, Optimus was surprised when they informed him that they were simply providing a diversion. Optimus realised that Sam was in danger, and rushed back to America in time to find Starscream attempting to abduct the boy. He jumped on Starscream's back, causing the Decepticon to flee and saving Sam from a kidnapping. {{storylink|Sam in Danger}}

===''Classified'' novels===
During the war on Cybertron, Optimus Prime fought in several [[Battle of Polyhex|battles]] in [[Polyhex]].

Optimus and Ironhide turned up to an attack on [[Nevada Test and Training Range]] by three Decepticons. Though he tried to talk them into abandoning the Decepticon cause, he was forced to kill them, especially when [[Bombshock (PCC)|Bombshock]] threatened to blow up some humans. Optimus took part in a meeting of some generals at the base, though he had to talk his way into doing so, as they were initially reluctant to include the aliens. Optimus disagreed that the Decepticons' target was [[Area 51]] and correctly deduced it to be [[Hawthorne Army Depot]]. When he arrived there with Ironhide, Bumblebee and Ratchet were already engaged in a battle with [[Reverb (ROTF)|Reverb]], however the Decepticon's personal [[force field]] made him impossible to hit and he did substantial damage to Prime. Once the shield was eliminated, Optimus defeated Reverb. Though Reverb asked Optimus to finish him off, Optimus instead took him prisoner. He also talked [[Marcus|General Marcus]] into allowing [[Kevin Bowman]] to join NEST. {{storylink|Transformers Classified: Switching Gears|Switching Gears}}

Lennox reported to Optimus via videolink on the halting of [[Alice]]'s rampage. Optimus mentioned that they should be more aggressive in tracking down Decepticons, but Lennox reminded him that NEST was low on resources. They decided on some "improvisations" in the form of newly-arrived Autobots. {{storylink|Nefarious issue 1|Nefarious #1}} Optimus was witness to Galloway balling out Lennox over the battle at [[Kingdom Petrochemicals]], but kept quiet. Afterwards, Lennox and Optimus discussed the [[Initiative|mysterious humans]] who had been seen at the petrochemical plant. When [[Ironhide (Movie)|Ironhide]] and [[Sideswipe (Movie)|Sideswipe]] came under attack from [[Soundwave (ROTF)|Soundwave]], Optimus parachuted in and bested Soundwave. Soundwave attempted to persuade Prime to let him go, but Prime decided that instead they would take him into NEST custody for interrogation. {{storylink|Nefarious issue 2|Nefarious #2}}

Optimus oversaw the preparations of the facilities for holding Soundwave, rather than face having to tell Major Lennox what they'd done. He was only delaying the inevitable, and Lennox was even more annoyed when the plane carrying Soundwave was shot down. {{storylink|Nefarious issue 3|Nefarious #3}} When NEST received a distress call from Galloway, who was under attack from [[Ransack (ROTF)|Ransack]], Optimus sent [[Skids (ROTF)|Skids]] and [[Mudflap (ROTF)|Mudflap]] to assist. He also reminded Ironhide that just because the man was a "pain in the aft" didn't mean they could avoid helping him. {{storylink|Nefarious issue 4|Nefarious #4}}

[[Image:Nefarious5 Prime already too late.jpg|thumb|right|250px|"They've already put the bomp in the bomp-a-bomp-a-bomp"]]
Soundwave led the Autobots to the location of the [[Initiative]] base in [[California]], but the base was gone. Despite this, Optimus still trusted Soundwave as he believe the organization they faced had access to Cybertronian technology. Soundwave pinpointed the mobile base as being in [[Utah]], so the Autobots headed there. Part way, Optimus felt the power of something very like the [[AllSpark]] being used and began to realize what they were up against. They reached Utah and began an assault on the [[Initiative base]], only to find themselves facing brainwashed Transformers. {{storylink|Nefarious issue 5|Nefarious #5}}

As the battle continued, Optimus tried to call out for their foe to surrender the AllSpark they possessed, however [[Carter Newell]], head of the Initiative, responded by trying to use the artifact to terminate all Cybertronian life. An injury courtesy of [[Reedman]] aborted the attempt, and Newell tried to flee. Optimus was forced to ram the truck he was in to obtain the AllSpark, but realized the only way to halt the rapidly-destabilizing Cube was to 
feed it his own [[spark]]. Luckily that turned out to be unnecessary, as [[Fortress (ROTF)|Fortress]] took the AllSpark from him and carried it into space, where it exploded. Optimus later noted that the Initiative data banks had been [[Soundwave (ROTF)|picked clean]] and wondered if anyone else could make an attempt to recreate the AllSpark. {{storylink|Nefarious issue 6|Nefarious #6}}

At [[NEST]] headquarters on [[Diego Garcia]], Optimus Prime tries to convince the Autobot refugees rescued from the clutches of the [[Initiative]] that they need more time to recuperate before returning to the battlefield. [[Armorhide (Movie)|Armorhide]] attempts to refute this, but only winds up proving Optimus's point when he accidentally calls him "[[Sentinel Prime (ROTF)|Sentinel Prime]]", and has to stop mid-flow to remind himself they are no longer on [[Cybertron (planet)|Cybertron]]. The exchange punctuates how important it is that the Autobots stop any more humans from exploiting Cybertronian technology, that being the purpose of the mission currently that very moment under way in eastern [[California]]. 

When [[Elita-One (Movie)|Elita-1]] returned to base after the mission, she shared a quiet moment with Optimus, losing herself in the sensations she could feel from the sisters whose spark she shared: The pain of Arcee's wounds, and the feel of Chromia's sword blade as she tested it against her fingertip. Prime quietly told her that she had never told him these things before, and she simply replied that he had never asked. {{storylink|Rising Storm issue 1|Rising Storm #1}}

When the Decepticons attacked [[Philadelphia]], Sam contacts NEST for aid, and the Autobots quickly mobilize, because of [[Arcee (Movie)|Arcee]] injuries, he wanted her to stay on base, but allowed her to go anyway. {{storylink|Rising Storm issue 2|Rising Storm #2}}

During the flight, Optimus tried once more to have Arcee sit out of the mission. Elita reminded Optimus that is was Arcee's decision, and her desire for revenge was as strong as Elita's. Optimus tried to explain to her that victory at any price comes at a high cost, recalling the time on Cybertron when Prime let such an emotion overcome him. Elita's anger boils over and she chastises him for leaving her behind on Cybertron, only to witness Chromia's death and die herself, and she came back to life only to fight and kill more Decepticons. Optimus reminds Elita that he too had experienced [[Transformers: Revenge of the Fallen (film)|death]], but Elita explained that when he died, the Autobots actually cared. {{storylink|Rising Storm issue 3|Rising Storm #3}}

After he arrived to Philadelphia, [[Jolt (ROTF)|Jolt]] tries to radio Prime to let him know that Shockwave has attacked the base, freed Fearswoop and slaughtered all the personnel, both human and Autobot, but his transmission breaks up before Prime can comprehend his meaning, a battered Elita crests the horizon, fresh from victory over Astrotrain, and screaming a warning that it all a trap. Alas, no sooner has the word "Shockwave" crossed her lips, than the cyclopean Decepticon himself rockets down out the air, landing with ballistic force square on top of Elita and crushing the life out of her, Enraged by the death of Elita-One and the other Autobots. Optimus Prime battled Shockwave destroying half of his face and body, Prime was about to kill Shockwave, till Shockwave's pet [[Driller]] came to save his master. {{storylink|Rising Storm issue 4|Rising Storm #4}}

===Titan Magazines ''Dark of the Moon'' prequel strips===

When a relic of [[Ark (DOTM)|an unknown UFO]] was discovered in Fiesole, [[Italy]], Optimus led a NEST team to secure the find. Starscream launched a surprise attack to claim it: Optimus ordered the human archaeologist to keep digging and fought the Decepticon, taking two blows before overpowering and thrashing him. But Starscream kept fighting, asking Optimus if there were things worth dying for. Optimus agreed and said he was willing to die to save Earth from Decepticons... at which point Starscream suckerpunched him and stole the artifact.

[[Image:Titan3-3_OpSoundwavefaceoff.jpg|thumb|left|350px|"Sorry Soundwave, you're going to need braces."]]

Optimus was left concerned about what the 'cons were up to {{storylink|Transformers Comic issue 3.1}} but found himself distract by two minor plots of Soundwave's, first fighting him to stop him crashing the Earth's economy {{storylink|Transformers Comic issue 3.2|Blood And Gold}} and then in [[Spain]] after he'd drawn [[Robert Epps]] and Bumblebee into an ambush. With Bumblebee near death, Optimus agreed to fight Soundwave without weapons if it would mean his comrade's survived, and he nearly died in the resulting fight. However, he managed to use Soundwave's sonic blasts and the local environment against his foe and emerged victorious. {{storylink|Transformers Comic issue 3.3|Dealing with the Devil}}

When Ratchet contacted NEST to let them know there was trouble at the [[Tech Museum of Innovation]], Optimus himself turned out to help chase off Starscream and Barricade. He later tried to convince the anti-[[Transformer|Cybertronian]] protesters that the Autobots were here to help, but Ratchet and Ironhide's actions during the fight had already convinced them of that, and their leader, [[Marcus Castor]], was already producing anti-Decepticon T-shirts. {{storylink|Transformers Comic issue 3.4|Automatic for the People}}

Sometime before the [[AllSpark]] was jettisoned into space, Optimus Prime personally witnessed the attack on [[Sentinel Prime (ROTF)|Sentinel Prime]]'s ship, the ''[[Ark (DOTM)|Ark]]'' and assumed that the ship was destroyed.

Before all of the Transformer race was forced into exodus of the planet, Optimus lead the final battle against Megatron and the Decepticons. Though he never thought he did a good enough job and sometimes wondered if the result would of been different, had Sentinel been leading.

[[Image:DotmOptimusPrimeReadytoRoll.jpg|left|thumb|300px|En garde!]]

Three years after Operation: Firestorm and the demise of the [[Fallen]], the Autobots and NEST took to dealing with human conflicts in the absence of the Decepticons. After receiving a tip from [[Alexi Voskhod]] he and [[Ratchet (Movie)|Ratchet]] arrived with NEST operatives in Chernobyl to investigate a report about the presence of Cybertronian technology on site. However, this investigation was interrupted by [[Shockwave (Movie)|Shockwave]] and his tamed [[Driller]], attempting to steal the component. After driving them off and cutting one of the Driller's tentacles off, Shockwave revealed himself before retreating. Optimus became disturbed to see Shockwave on Earth but was more horrified to see that the piece of technology, to his disbelief, was a fuel cell from the ''Ark''. 

Optimus returned to NEST headquarters and refused to transform or speak to anyone until National Intelligence Director [[Charlotte Mearing]] arrived. It wasn't until Ironhide hit him on the roof that he transformed very violently and demanded an explanation from Mearing, which she offered along with the corroborating testimony from [[Buzz Aldrin]] that the information had been known by a select few. Optimus explained that the ''Ark'' carried important technology that would have given the Autobots a clear victory in the Cybertronian Civil War, and was piloted by his predecessor and mentor, Sentinel Prime. Optimus mounted an expedition to the [[Moon (moon)|Moon]] aboard the ''[[Xantium (DOTM)|Xantium]]'' with Ratchet to explore what was left of the ''Ark''. 

The two Autobots explored the ship and opened the crash vault in which Sentinel Prime had locked himself. Optimus pulled Sentinel from the vault and brought his former mentor back to Earth where he used the [[Matrix of Leadership]] to revive Sentinel. The former Prime awoke and attacked in confusion. After calming his mentor down, Optimus explained that they recovered five pieces of his technology, but Sentinel was disturbed by this news, explaining that purpose of the "pillars" was to form a [[space bridge]]. Optimus declared their peaceful uses to the humans, but Director Mearing objected, citing possible uses like transporting weapons and troops to the planet. The pillars were placed in human custody.

[[Image:DOTM-SentinelOptimusMatrix.jpg|right|thumb|300px|"Sorry Optimus, I don't want it. Because when I kill someone, I want them to ''stay'' dead."]]
After this meeting, Optimus took Sentinel for a tour on the countryside at sunset, during which Sentinel commented on the peace and beauty of Earth. Optimus bowed and offered the Matrix of Leadership to him, declaring him the rightful Autobot leader. Sentinel refused, saying that while he was Optimus's master on Cybertron, here on Earth, Optimus was the more experienced of the two. After learning from [[Sam Witwicky|Sam]] that the Decepticons were targeting Sentinel because he alone could control the pillars, the Autobots were ordered to protect him. Running behind the group, Optimus returned to the NEST base only to find that Sentinel had betrayed the Autobots and NEST, killed [[Ironhide (Movie)|Ironhide]], and escaped with the pillars. Mearing declared the subterfuge and defeat as the fault of the Autobot leader. Optimus voiced no defense at this accusation. 

[[Image:DOTMSentinelOptimus.jpg|left|thumb|300px|Sentinel, can you put that sword somewhere else so we can talk?]] 

Optimus subsequently tracked his mentor to the National Mall reflecting pool and attempted to stop him from bringing an invasion force to Earth after learning of his deal with [[Megatron (Movie)|Megatron]]. Sentinel fought and bested Optimus but spared his life, commenting that Optimus would come around to his way of thinking. Optimus refused to be part of Sentinel's plan. 

Later, Sentinel denounced Prime and his Autobots as rebels, and demanded that human beings exile them. Fearing an attack from at least 200 hidden and entrenched Decepticon troops, human leaders ordered the Autobots off the planet. Prime complied with the order and gathered his troops to leave Earth immediately in the ''Xantium''. Despite Sam's pleadings to reveal his plan to fight back (and inform the Decepticons who had bugged him), Optimus replied they had no plan. He reminded Sam that the human was his friend and the fight against the Decepticons would now be his own. As he boarded the ship he told Bumblebee to make his farewell with Sam short. Shortly after takeoff, [[Starscream (Movie)|Starscream]] attacked and destroyed the ship. Optimus and the Autobots were presumed dead.

However, the Autobots had hid themselves in one of the disengaged boosters and survived, thanks to the ''Xantium'''s builders, the [[Wrecker]]s. Optimus and the other Autobots headed for Decepticon-controlled [[Chicago]] and arrived there just in time to rescue Sam, [[Robert Epps|Epps]], and a team of former NEST soldiers from a Decepticon [[Orbital Assault Carrier|fighter]]. Optimus explained that the Decepticons would never leave Earth in peace, and that Earth's leaders needed to believe they had gone so that they could see the truth. As the other Autobots arrived on-scene, Optimus announced that they were going to take the battle to the Decepticons in the name of freedom. The Autobots then transformed and drove into the city as Sam and Bumblebee using the Assault Carrier went to rescue Sam's girlfriend [[Carly Spencer]]. They arrived after the Carrier crashed and told Sam to get ready for battle.

[[Image:DOTM-Wreckers-Prime-Cables.jpg|right|thumb|300px|The proud Autobot leader in a moment of dignifed repose.]]

En route to Sentinel's location and that of the control pillar, Optimus and the Autobots were ambushed from below by Shockwave and his Driller. The Driller disengaged Optimus's trailer, but the Wreckers distracted the Decepticon assassin. Optimus managed to recover the flight tech from his trailer and attack the Driller from the air just as it prepared to eliminate Sam, Carly, Epps and his soldiers. Optimus swooped through a building and punched a fatal blow through the Driller. Shockwave, angered by the destruction of his pet, shot at Optimus from the street. Optimus fell through a nearby unfinished building and was caught up in the wires of a construction crane. While the Wreckers tried to get him loose, Sentinel engaged the pillars and started to transport Cybertron into Earth's orbit. 

The Wreckers managed to free their leader, who swooped into the main battlefield and killed eleven Decepticons single-handed. Charging toward Shockwave, who had already been damaged by NEST soldiers, Optimus then ran his spiked fist through his side and tore out his eye. He then used his enemy's cannon to blast the control pillar, temporarily stalling the transportation of Cybertron.

[[Image:DOTMScrapper.jpg|left|thumb|300px|Banzai!]] 

Optimus demanded his former master to come down and confront him. Sentinel complied, but when Optimus started to get the upper hand, Sentinel called upon Decepticon fighters to fire at his former pupil. Pinned down by the enemy fire, Optimus was prevented from attacking until the fighters were destroyed. Optimus engaged Sentinel again, but this time he cut off Optimus's right arm after a lengthy sword fight. As Sentinel prepared to deliver the final blow, [[Megatron (Movie)|Megatron]] charged up, shot Sentinel in the back and proceeded to heavily damage the older Prime. Megatron then proposed a truce to Optimus on the condition that he would be in charge again. After all, as Megatron put it, "who would you be without me, Prime?" Realizing that Megatron could not be trusted, Optimus replied that it was "time to find out." He swung his axe at Megatron, disarmed him and took the axe to Megatron's head and ripped it out, taking Megatron's spine with it, killing his eternal foe.

[[Image:DOTM Autobots NEST victorious.jpg|thumb|right|280px|Hey, Ratchet, when you have a moment...]]

The damaged and helpless Sentinel explained that Optimus had to see why he had betrayed his own side, for their race's survival in the long run. Optimus refused and told Sentinel he had betrayed ''himself'' and the values he was thought to have upheld as a Prime. Despite his former master's plea for mercy, Optimus fired two shots from Megatron's fusion shotgun, executing Sentinel. With Cybertron now (presumably) destroyed, Prime, Bumblebee, Ratchet, Dino, Sideswipe, and the Wreckers finally accepted Earth as their new home, and Optimus declared that the Autobots would never forsake the defense of Earth or its people. {{storylink|Transformers: Dark of the Moon (film)|Dark of the Moon}}

{{Note|In some early drafts of the movie, Optimus accepted Megatron's sincere truce, allowing him and his forces to return to Cybertron. Furthermore, he would have ended Sentinel's life with his own [[Cosmic Rust (disease)|Cosmic Rust]] blaster in a round of poetic justice. Some of these scenes can still be seen in various adaptations.}}

====Autobot campaign====
Optimus Prime provided intelligence and missions to Bumblebee in his search for the AllSpark. Eventually, the clues led the Autobot to Sam Witwicky. After saving Sam from Barricade, Bumblebee finally completed preparations for the Autobots to arrive on Earth. Once on Earth and disguised as a truck, and having informed the two teenagers of their mission, Prime and the Autobots were discovered by Sector Seven. Optimus sent Jazz on a high-speed <strike>destruction</strike> distraction mission, then sent Ironhide to rescue Jazz from a double-threat posed by the government agents and various Decepticon scouts. When Bumblebee was captured, Optimus Prime chased the helicopter which from which the small Autobot was dangling. After a lengthy pursuit, Optimus managed to catch the net, only to be thrown off by another Cybertronian [[transition form|meteor]] passing nearby. As Bumblebee was carried away, Optimus promised he would not fail him again. Jazz informed him that the meteor was not an Autobot and Optimus confronted the new threat, who turned out to be the Decepticon triplechanger [[Shockwave (Movie)|Shockwave]]. The two battled it out across [[Tranquility]] before Optimus finally destroyed him, and in doing so, overheard [[Starscream (Movie)|Starscream]]'s transmission revealing the location of the AllSpark.

Optimus then returned to an intel role as he guided Bumblebee in his mission to retrieve the AllSpark from Hoover Dam. Unfortunately, the Decepticons managed to free Megatron, leading to the final battle in Mission City. As the Autobots engaged in an all-out urban war with the Decepticons to protect Sam and the AllSpark, things seemed to take a turn for the worse as Megatron finally arrived. But before the Decepticon leader could claim the Cube, Optimus Prime attacked. The two leaders duked it out until Megatron was finally on the ground, seemingly devoid of life. Optimus knelt to take the AllSpark as Sam handed it to him, but Megatron suddenly awoke, leaping at the Autobot with his chain-flail out, and making one last attempt at defeating his adversary. Optimus grabbed the chain, pulling Megatron in closer, and with the AllSpark clutched in his fist, delivered a punch through Megatron's spark. As Megatron died Optimus reflected on the losses and rewards of this battle, as the Autobots have a new home. Optimus planned to guard the humans in secret, "For freedom is the right of all sentient beings." {{storylink|Transformers The Game (console)|Transformers The Game}}

====Decepticon campaign====
After Bumblebee, Jazz and Ironhide were all killed in Mission City, Sam and Mikaela informed their deaths to Optimus. Optimus noted their sacrifice and decided to defeat Megatron. In the final battle, Optimus Prime confronted Megatron at the top of a building, and fought back against Megatron while protecting Sam. Eventually beaten to the ground, and as he desperately crawled for the AllSpark, Megatron smashed his head with his flail, before using the Cube to destroy humanity. {{storylink|Transformers The Game (console)|Transformers The Game}}

Optimus helped to advise his warriors in some of their mission to try locate the Allspark. Arriving on Earth, Optimus met up with the other Autobots to give further commands to his troops. [[Create-A-Bot (Autobot)|Create-A-Bot]], the new rookie, was eager to help in the cause, but Optimus tells him to sit back while the grown-ups take care of business. After Jazz learned that Sector 7 possessed both Megatron and the Allspark, Optimus ordered Bumblebee to create a diversion so that they could get out of the city, but Create-A-Bot, fed up with the bureaucracy defied Optimus's orders and interfered in Bumblebee's mission, resulting in the scout's capture. After an argument with Ironhide over their priorities, the Autobots began making their way to the Hoover Dam.

After learning from Jazz that Bumblebee was being held in the dam, Optimus took pity on Create-A-Bot and allowed him the chance to redeem himself by freeing Bumblebee. After guiding Bumblebee to his weapon chip and the Allspark, Optimus and Bumblebee made their way down the highway when they were confronted by Barricade and a drone, and after defeating them Optimus realised they were a diversion so that they could unfreeze Megatron. Searching for his nemesis, he instead encountered Brawl, who he eventually killed before returning back to the city, where he rendezvoused with Create-A-Bot and Bumblebee with the Allspark, Megatron arrived and Optimus fought back. During the fight, Create-A-Bot sacrificed himself to save his commander. Megatron defeated, Optimus commends the young Autobot as a war hero, and sends out an interstellar message to any Cybertronians living among the stars. {{storylink|Transformers Autobots/Decepticons|Transformers: Autobots}}

=====Autobot campaign=====
[[Image:ROTF game Optimus Prime.jpg|thumb|right|300px|One shall stand, one sha— oh, you know the drill.]]
Optimus Prime served as the Autobots all around fighter. Weapons wise, he possessed dual laser rifles and dual shell cannons. In melee combat, he possessed [[Dual Energon Swords|Dual Energy Swords]] in each hand. Finally, with his valiant leader ability, he could generate a shield around himself which would prevent his energy from dropping past 1%.

After overseeing Ironhide's defeat of [[Sideways (ROTF)|Sideways]] and Ratchet's rescue of Ironhide, Optimus Prime took to the field when a previously unknown Decepticon named [[Demolishor (ROTF)|Demolishor]] began attacking the [[Shanghai]] waterfront. Optimus was finally able to defeat him, but Demolishor gave a single warning before he was killed: "The Fallen shall rise again". Optimus and the Autobots were at a loss as to what he meant. Back in the United States, Sam Witwicky gave Mikaela Banes a fragment of the AllSpark that he had discovered, which the Decepticons soon sought. Prime dispatched Bumblebee to rescue her. Following this, the Decepticons launched a raid on the city's oil refinery, where Ratchet rescued several engineers. Finally, Ironhide escorted a NEST team to safety in the city's canals. Their victories were short lived. The Decepticons soon learned about the AllSpark shard on Diego Garcia, stealing it to revive Megatron. Although [[Breakaway (ROTF)|Breakaway]] managed to save the fleet, Megatron was reborn. He soon made an attack on Sam, trying to access information in his mind downloaded from the AllSpark. Bumblebee managed to rescue him. In light of these attacks, Optimus decided to give NEST the [[Axiom Gun]] to better defend themselves against the Decepticons. The escort came under Decepticon assault, but Prime was able to beat back the attackers and deliver the Axiom Gun to NEST. Soon afterwards, Bumblebee escorted Sam to meet with [[Seymour Simmons]], who told him of Jetfire, who then took the boy to Egypt.

While there, Jetfire explained what was going on: Eons ago, Optimus's ancestors, the [[Thirteen|13 founders]] of the [[Dynasty of Primes]], built a star harvester to convert the energy of the sun into [[Energon]]. When they discovered the humans, they upheld their rule of the sanctity of life, but one of the Primes defied the rule and murdered his twelve brothers. This Prime was known as The Fallen, but the star harvester was hidden from him. While Sam made inquires to the [[Tomb of the Primes|Tomb of the Twelve]], Megatron and Starscream arrived in an attempt to learn the harvester's location and kill Sam. Optimus Prime was able to defeat both Decepticons with Jetfire's help, but Jetfire was stabbed in the back by Megatron. Dying, Jetfire offered his parts to Optimus, as only a Prime could defeat The Fallen. Finding the harvester at the [[Great Pyramid of Giza]], Optimus challenged The Fallen. Despite The Fallen's powerful command of telekinesis and pyrokinesis, Optimus Prime was able to get past his defenses and kill The Fallen by stabbing him through the face. On the return trip home, Sam expressed gratitude at seeing the sunrise, and told Optimus he would have to trust him on it. Optimus Prime replied that he had always trusted Sam, and always would. {{Storylink|Transformers: Revenge of the Fallen (Xbox 360/PS3/PC)|Revenge of the Fallen (Xbox 360/PS3/PC)}}

When the revenant Megatron and the Decepticons rampaged across the United States of America, Optimus Prime faced him in a major city on the East Coast. The two leaders engaged in a titanic struggle that shook the city, but despite being aided by many Autobot drone units, Optimus was seemingly destroyed. However, much later, Optimus Prime reappeared when Megatron's master, The Fallen, activated the Star Harvester to drain Earth's Sun. The Autobot leader revealed that The Fallen's promise to make Megatron a Prime was a lie, as Primes were born, not made. When Megatron demanded his reward, The Fallen reneged on his promise. As the master and disciple of evil began to fight, Optimus left to find a way to disable the Harvester. {{Storylink|Transformers: Revenge of the Fallen (Xbox 360/PS3/PC)}}

A signal in [[Shanghai]] led Optimus to discover a Decepticon invasion force there. He fought the foe solo, and followed an [[AllSpark]] signal to [[Starscream (Movie)|Starscream]]. Starscream managed to escape, and NEST reported that HQ was under attack. As he had to hang around to help clean up the mess in Shanghai, Optimus sent [[Bumblebee (Movie)|Bumblebee]] and [[Ironhide (Movie)|Ironhide]] to help. Bumblebee was defeated by Starscream, but told Optimus that Starscream had said something about the [[Matrix of Leadership]]. Believing he knew where the Decepticons were headed, Optimus went to find an old friend, [[Jetfire (ROTF)|Jetfire]].

In Egypt, Optimus lost contact with NEST while investigating an area. He told Bumblebee to rendezvous with Jetfire at the [[Great Pyramid of Giza|Great Pyramid]], warning Bumblebee that he believed an energy signature he was detecting was [[The Fallen]]. Bumblebee later reported that [[Devastator (ROTF)|Devastator]] had defeated Jetfire and taken the Matrix. By the time Optimus reached the site, [[Megatron (Movie)|Megatron]] had taken Bumblebee hostage and had possession of the Matrix. Optimus combined Jetfire's parts with his own, gaining enough strength to defeat Megatron. Exhausted by the fight, Prime was then confronted by The Fallen, but used the power of the Matrix to defeat the ancient Decepticon. {{storylink|Transformers: Revenge of the Fallen (Glu)|Revenge of the Fallen (Glu)}}

When [[Bumblebee (Movie)|Bumblebee]] was in the process of stopping [[Starscream (Movie)|Starscream]]'s plan to destroy a city, Optimus turned up at the last moment to defeat the Decepticon and hog the glory. {{storylink|Victory Is Sweet}}

====(Xbox 360/PS3)====
Three years after the defeat of the Fallen, Optimus attempted to hack into Decepticon transmissions in order to turn the tide in the war. He ordered Bumblebee to implant a virus into the transmissions. Just when Bumblebee was on his way out, a few Decepticons discovered him and decided to report back to Megatron. Optimus ordered Bumblebee to destroy their communications and after Bumblebee accomplished that task, he and Sideswipe saved him from a Decepticon ambush. However, the information in the transmissions allowed Optimus to get Ironhide and Ratchet to take care of an attack in [[Detroit]]. Later, Megatron learned of the virus and got Soundwave to remove all of the Decepticon information, getting rid of the Autobot's advantage. Starscream did, however, take a [[MechTech]] weapon with a tracking device on it. This allowed the Autobots to find the Decepticon hideout and attack it. Optimus got inside and fought Megatron. However, Megatron defeated Optimus and sent him down to a cryo chamber. Optimus would later discover that the chamber contained Shockwave and his pet Driller, who had been frozen by the Soviets and that Megatron's plan was to free them out of captivity. After a brief battle, Optimus had failed to prevent Shockwave from emerging out of his frozen state and was about to kill him when the Driller arrived and escaped with Shockwave. Optimus then vowed to not rest until every Decepticon was found and brought to justice. {{storylink|Transformers: Dark of the Moon (Xbox 360/PS3)| Dark of the Moon}}

====Autobots/Decepticons====
[[Image:DOTMDS Optimus Prime.jpg|thumb|left|200px]]
Concerned that the Decepticons were behind recent attacks downtown, Optimus sent [[Bumblebee (Movie)|Bumblebee]] to investigate and, it turned out, he was right. With more information, Optimus contacted [[Ironhide (Movie)|Ironhide]] to alert him that the Decepticons were up to something involving the possible resurrection of the [[Constructicon (ROTF)|Constructicon]]s. He encountered [[Ratchet (Movie)|Ratchet]] in the field, and took over Ratchet's mission as the medic was more valuable at base. During the course of the mission, Optimus encountered [[Soundwave (ROTF)|Soundwave]] and chased him to a stadium where the Autobot leader was triumphant. Sometime later, the Decepticons attacked the Autobots' Pacific island base, and Ratchet and [[Wheeljack (Movie)|Wheeljack]] warned Optimus that [[Crowbar]] was around somewhere. Optimus bashed many Decepticons but didn't find Crowbar. When the Decepticons invaded a NEST base, Optimus was surprisingly keen for the Autobots to let [[Soundwave (ROTF)|Soundwave]] get away. They eventually tracked the Decepticons to a base in [[Siberia]], and Optimus insisted on going in alone, only to be overcome by [[Megatron (Movie)|Megatron]] and [[Shockwave (Movie)|Shockwave]], who got away despite the best efforts of the other Autobots. {{storylink|Transformers: Dark of the Moon: Autobots/Decepticons|Dark of the Moon: Autobots/Decepticons}}

===''Transformers: The Ride''===
[[Image:OptimusRide.JPG|thumb|right|300px|"Great job doing nothing, recruits"]]
Optimus met up with the other Autobots after [[Evac (Ride)|Evac]] had acquired the Allspark fragment, and complimented them on their good work. He told them  to roll out, and proceeded to engage Megatron in battle. Megatron angrily demanded the Decepticons attack.

Later, Optimus engaged Megatron when he attempted to attack Evac and the [[You|NEST recruits]] to steal the fragment. After grappling with him for a few seconds, Megatron pinned Optimus and fired a grenade at Evac, only to have Evac evade it and escape. 

Optimus later appeared, thrown by Megatron onto a building. Megatron again attempted to attack Evac and his "passengers", but Optimus interrupted, cutting a piece of Megatron's face. Megatron, however, fought back and easily dispatched of Optimus, but this once again allowing Evac to escape.

When Megatron attempted to attack Evac once more, Optimus had again intervened. Megatron attacked Optimus again, but Evac, fed up with doing nothing but running, took this opportunity to fight back, and charged Megatron. While Optimus held him in place, Evac [[Transformers (film)|jammed the Allspark into Megatron's chest]], overcharging him and killing him. Optimus appeared one last time to congratulate Evac and the recruits on their bravery.

==Commercial appearances==
* As part of the hype buildup to the first movie's release, Optimus Prime made a brief cameo at the 2007 MTV Movie Awards, interacting with host Sarah Silverman. The scene spliced Silverman into pre-existing movie footage, but featured new dialogue recorded for the event by Peter Cullen. Prime heavily hinted that he wanted to present an award, but was rejected for a regular MTV fan.

* According to a tie-in advertisement for [[Burger King]], Prime likes his Whoppers with no onions, no cheese, extra pickles, with a side of ????. However, due to a cruel twist of fate, he can never enjoy the sweet taste of beefy victory (and all because he needed a driver for him to receive his order). He saved the world from the Decepticons, and still he can't even have it his way? Where's the justice?

* Optimus Prime (in truck mode) made an appearance at [[BotCon 2007]], alongside the [[Sector Seven Mobile Command Unit]]. He was available for pictures all weekend. He made a second appearance at [[BotCon 2009]].

* Optimus threw a trailer during his appearance on an [[M&M's]] commercial.

* During the 2009 NBA Finals, a commercial aired where [[The Master Builders|Optimus made a slam dunk]] and shattered the backboard.

* On [[July 6]]th 2009, Optimus appeared on ''The Late Show With David Letterman'' to declare the "Top Ten Things That Sound Cool When Said By A Giant Robot". Optimus said it was nice to be there, although David was ''clearly'' concerned by having an 28-feet tall robot in the studio because of a bad history of robots messing up the place, and during the presentation Letterman decided there was something about Prime he didn't like. Anyway, the top ten was:
<ol>
<li value="10">"Jergens lotion leaves my hands silky smooth."</li>
<li value="9">"Do you have these khakis in size 114?"</li>
<li value="8">"My perfect night involves a pint of Haagen-Dazs and season three of ''Sex and the City''."</li>
<li value="7">"Man do I love me some 'taters."</li>
<li value="6">"It was so hot in Central Park, I saw a squirrel rubbing sunblock on his nuts."</li>
<li value="5">"You seemed a little pitchy, dawg."</li>
<li value="4">"Brody Jenner has added you as a friend on Facebook."</li>
<li value="3">"Live from New York, it's Saturday night."</li>
<li value="2">"My parents wanted me to be a Rabbi."</li>
<li value="1">"All the slammin' shorties in the house say 'Yeah'."<ref>[http://lateshow.cbs.com/latenight/lateshow/video_player/index/php/991507.phtml Lateshow CBS archive video of Optimus's guest spot.]</ref></li>
</ol>

* To promote the DVD and Blu-ray release of ''Revenge of the Fallen'', Paramount set up a website where US fans could request Optimus call up their friends, warning them of Starscream's attempts to recruit human civilian allies.

*In the Discovery Channel promo, "The World Is Just Awesome," Optimus made a brief cameo, singing the words "boom-de-ya-da, boom-de-ya-da."<ref>[http://www.youtube.com/watch?v=a0jZzBEKIMc Discovery commercial] on YouTube.</ref>

*Prime (voiced by Cullen, but not animated by ILM) appeared to promote a NASA competition to vote for videos made by children about NASA's impact on commonplace technology.<ref>[http://ipp.gsfc.nasa.gov/optimus/ NASA Optimus Prime]</ref>

*Optimus appeared in truck mode at [[Toy Fair 2011]]. He got a $115 parking ticket.<ref>[http://www.dailymail.co.uk/news/article-1357327/Transformers-truck-gets-parking-ticket-toy-fair.html ''Daily Mail'' article on Prime's fine.]</ref>

* When Optimus' design was first revealed, [[GEEWUN|many fans of the Generation 1 series objected to the flames seen on Prime's body]]. When asked in an interview why he put the flames on, [[Michael Bay]] claimed he liked them because it was "cool". It was later revealed on a special featurette on the DVD that the flames were added because, apparently, red is not very good to film on camera, so Bay chose a blue truck but used the flames so that when Optimus transformed, the layout would result in maintaining his iconic red chest.

* In the director's commentary of the 2007 Transformers DVD, Michael Bay said that he had told the animators to seek inspiration from Liam Neeson in creating Optimus Prime's body language. ''Awesome''

* Optimus Prime's ''Rise of the Chevy Autobots'' codename, "10-22", is [http://www.truckercountry.com/cb-terminology.html#10c CB radio slang] for "report in person to." As in "Bumblebee, 10-22 to 10-22."  Cute, huh?

* [[TakaraTomy]] officially recognizes Optimus Prime's vehicle mode as a [http://www.kenworth.com/2100_vir_w900.asp Kenworth W900 truck], even though the vehicle used for filming was a modified Peterbilt 379, a different model from a different brand, although both are made by the PACCAR company.<ref>[http://www.edmunds.com/insideline/do/Features/articleId=121424?tid=edmunds.il.home.photopanel..2.* Article at Edmunds.com on some of the vehicles used in the movie]</ref>
[[Image:Movie OptimusPrime truckrear.jpg|right|150px|thumb|]]

* Optimus Prime's truck mode is apparently intended to haul a flatbed trailer, based on the presence of the large silver "headache rack", a piece of optional equipment that protects the driver in case a flatbed load breaks free during braking.  It is generally not installed on trucks hauling enclosed container trailers.  

[[Image:Movie Prime Trucklogomistake.jpg|right|150px|thumb|In the darkness, a PA will misread "Truck A" as "Truck B", and there shall be wailing and gnashing of teeth — Revelation 11:7.]]

* When Optimus Prime scans a truck for his new body, the passing truck has what appears to be an Autobot sigil on its grill, but the actual truck that Prime turns into at the end of the scene has a much wider, flatter symbol on the grill, which looks rather more like that of Peterbilt. Then, Prime has an Autobot sigil on his grill while driving to meet the other Autobots.

* According to the free trading cards from the Boston Globe, Optimus is 28 feet tall, weighs 4.3 metric tons, and his primary weapon is an [[Ion blaster|ion blaster]]. (Considering Optimus's height, however, this weight would seem implausible.)

*The [[Milton Bradley]] [[Transformers Battling Card Game]] depicts Prime with a unique a magnetic grapple attack, fired from the side of his arm. It also declares his forearm gun to be a chain gun (it's an ion blaster in other sources), and has him using a "judo kick", which... while it may not be out of the realm of plausibility for Prime to have learned an Earth martial art, judo does not actually '''use''' kicks, being focused on throwing moves. Oops.

* The Optimus Prime computer generated model consisted of 10,108 individual parts, 1,830,898 polygons, 27,744 rig nodes, and 2336 texture maps.  The volume of all pieces combined came to 5445 cubic feet.<ref>Robertson, Barbara (2007). Heavy Metal. ''Computer Graphics, 30''(7), 12-17.</ref>

* It said in the Autobots game in the DS, Prime's father was killed by Megatron.  However, since it is also widely known that Prime and Megatron were brothers, Megatron killed his own dad.  Not that this is surprising, though.

[[Image:ROTF Optimus trailer super mode.jpg|thumb|right|250px|"One shall be scrawny...One shall be brawny"]]
* Optimus was supposed to combine with a trailer for ''Revenge of the Fallen'', something for which [[Ben Procter]] and [[Josh Nizzi]] drew up designs. In the end, Nizzi designed the combination with Jetfire. However, the idea of Optimus combining with his trailer was not forgotten, and showed up on screen in ''Dark of the Moon''.

* According to [[TakaraTomy]] marketing director [[Masahiko Yamazaki]], for the Japanese dub of ''[[Transformers Animated (cartoon)|Transformers Animated]]'', the [[Optimus Prime (Animated)|Optimus]] featured in that show would become a young version of this one. Ultimately, this didn't make it into the end product as the show went largely unchanged.
