Optimus Prime (Tyran)

Optimus Prime is the leader of the Autobots. Once, long ago, he was a co-ruler of Cybertron together with his brother, Lord High Protector Megatron, but Megatron grew greedy and attempted to claim the All Spark for himself. Optimus rose to stand against him. 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 All Spark was jettisoned into space, dooming Cybertron to a slow death and his people to nomadism. 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.

"A necessary sacrifice to bring peace to this planet. We cannot let the humans pay for our mistakes."

Prime Directive prequel comics


For two generations, Optimus Prime ruled Cybertron side-by-side with Megatron. The two personalities created a balance; Prime was fair while Megatron was firm. However, when Megatron revealed his intentions to steal the All Spark and use it for evil, selfish gain, Prime reacted accordingly. He formed the Autobots, a militia from the civilians around him, but they fared terribly against Megatron's armies, the Decepticons. Ultimately, Prime was forced to eject the All Spark into space to keep it from his nemesis. Unfortunately, Megatron tracked the All Spark to Tyger Pax, where Bumblebee's unit was trying to slow down the Decepticons. Prime and the Autobots were held up in Simfur, and unable to come assist. Fortunately, Bumblebee's unit succeeded, and the All Spark was ejected into space, but Cybertron was sentenced to a slow death. The Autobots were forced to abandon the planet.

Thus the focus of the war between Autobot and Decepticon shifted. The All Spark's ejection was only a stall. No longer did Prime have to keep Megatron from stealing the All Spark, instead Prime and his Autobots must hunt down the All Spark, wherever in the universe it landed, before Megatron could.

Transformers: Ghosts of Yesterday prequel novel
Optimus Prime led the search for the All Spark in the Ark, a transport vessel. When they came across an abandoned solar system, they located 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. Prime managed to defeat Blackout, Scorponok, and 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 and the alien ship. They fell into a cavern network, where they were further attacked by 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 "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 All Spark 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.

"One shall stand. One shall fall."

- Optimus Prime as he takes on Megatron



The leader of the Autobots, Optimus Prime came to Earth shortly after Bumblebee sent his comrades a beacon. Upon atmospheric re-entry, Prime managed to land outside of Tranquility's inhabited areas. While Sam and Mikaela watched, Optimus transformed in his protoform and fled his landing place. From atop a hill, he quickly trans-scanned the form of an Earth Peterbilt Semi-truck, thus configuring his body to transform into it. Prime, Jazz, Ratchet, and Ironhide met up with Bumblebee and his human friends, Sam Witwicky and Mikaela Banes in an alley. In one of the most extended transformations in the multiverse, Prime assumed his robotic form before the stunned humans. After confirming Sam's identity, Prime introduced himself and his team. When Mikaela asked of the Autobots' intentions, Prime explained the search for the All Spark, the betrayal of Megatron, and why Sam was important to their search.



Glasses that belonged to Sam's ancestor, Captain Archibald Witwicky, contained the location of the All Spark 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. 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 power lines, then crushing a greenhouse during his fall, causing further problems thus making Ron think there was an earthquake and ran under the table asking Judy to "duck and cover." When the parents came to investigate, Prime's attempt to avoid discovery caused the house to shake, as Ron jumps into the an old cast-iron tub and stated that he hates earthquakes; 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 he should kill the parents as they were very irritating, 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.

Optimus Prime sent the Autobots in pursuit of the SUV that contained Sam, Mikaela, and Sector Seven's director, 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 ticked 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.

Optimus Prime, now in possession of the glasses which could tell him the location of the All Spark, 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 All Spark. Jazz 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 a "primitive and violent race", but Prime countered that when their time had come, the Cybertronians had been 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 All Spark: if they could not defeat the Decepticons, Prime intended to merge the Cube with his spark. Though this would destroy the All Spark, Ratchet cautioned Prime against this, as it would also kill him as the Cube is raw power. Prime believed that this was acceptable, vowing not to let another race suffer the mistakes of the Transformers. The glasses placed the All Spark at Hoover Dam where, luckily, Bumblebee and the young humans were taken.

Optimus Prime's team met up with Sector Seven, Bumblebee, Sam, and Mikaela enroute, who had planned to hide the All Spark in nearby Mission City. While on the highway CA-210, he was attacked by 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 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 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 from his forearms. The power up time allowed Prime to draw his 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 All Spark.

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 and stay close to him; 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, Optimus told the boy that if he could not defeat Megatron, that Sam must put the All Spark into his chest which would destroy it. As Sam sought cover, Optimus faced down Megatron, 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 All Spark, 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 All Spark into his chest. Sam instead thrust it into Megatron's chest, killing the Decepticon leader and destroying the All Spark.

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. Prime eulogized his comrade, then commented that they had gained new comrades in the humans, and was honoured 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 All Spark in Megatron's chest cavity and removed it, then permitted the humans to dispose of the Decepticon corpses by dumping them into the 2nd deepest part of the ocean.



Though Megatron was killed and his Decepticons were defeated, Starscream leaving the planet, the All Spark 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.

Transformers The Game

 * Voice actor: Peter Cullen

Optimus Prime provides intelligence and missions to Bumblebee in his search for the All Spark. Eventually, the clues lead the Autobot to Sam Witwicky. After saving Sam from Barricade, Bumblebee finally completes preparations for the Autobots to arrive on Earth.

Once on Earth, and having informed the two teenagers of their mission, Prime and the Autobots are discovered by Sector 7. Optimus sends Jazz on a high-speed destruction distraction mission, then sends Ironhide to rescue Jazz from a double-threat posed by the government agents and various Decepticon scouts.

When Bumblebee is captured, Prime transforms and chases the chopper which from which the small Autobot is tied. After a lengthy chase, Prime manages to catch the net, only to be thrown off by another Cybertronian meteor. As Bumblebee is carried away, Optimus promises he will not fail him again. Jazz informs him that the meteor is not an Autobot. Prime confronts the new threat, who turns out to be the Decepticon Triple Changer Shockwave. The two battle it out across Tranquility before Optimus finally destroys him. But not without overhearing Starscream's transmission revealing the location of the All Spark.

Optimus then returns to an intel role as he guides Bumblebee in his mission to retrieve the All Spark from Hoover Dam. Unfortunately, the Decepticons manage to free Megatron, leading to the final battle in Mission City.

As the Autobots battle it out with the Decepticons to protect Sam and the All Spark, things seem to take a turn for the worst as Megatron finally arrives. But before he can claim the cube, Optimus attacks him.

The two battle it out until Megatron is finally on the ground, seemingly devoid of life. Optimus then kneels to take the All Spark as Sam hands it to him. Megatron however awakens, leaping at Optimus with his chain-flail out, and making one last attempt at defeating his adversary. Optimus grabs the chain, pulling Megatron in closer, and with the All Spark clutched in his fist, delivers a punch through Megatron's spark. As Megatron dies, Optimus reflects on the losses and rewards of this battle, as the Autobots have a new home. Optimus plans to guard the humans in secret, "For freedom is the right of all sentient beings."

Arriving late on Earth, Optimus meets up with the other Autobots to give further commands to his troops. Create-A-Bot, the new rookie, is eager to help in the cause, but Optimus tells him to sit back while the grown-ups take care of business. Getting fed up with the bureaucracy, Create-A-Bot finally defies orders and completes a mission against Optimus's council. After nearly getting himself and the other Autobots killed, Create-A-Bot apologizes to Optimus personally. Taking pity on the newcomer, Optimus lets him off with a stern warning, and they move out together to face Megatron. During the fight, Create-A-Bot sacrifices 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.

Transformers: Decepticons

Landing on Earth, Optimus quickly joins the other Autobots to attempt to stop the Decepticons. He doesn't actually appear, however, until Megatron himself is released and Starscream escapes with the AllSpark. He steps in to thwart the maniacal leader of the Decepticons, but alas, is struck down, left in the streets while Megatron gives chase to his traitorous second-in-command. You can ironically cheat by jumping on a building and shoot him then.

Titan Magazines
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.

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 All Spark's ejection could spread war to other planets—but too late to stop the launch...

Almost immediately after the final battle against Megatron, Optimus Prime had to lead the Autobots against a horde of 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.

In the alternate reality of Twilight's Last Gleaming, Megatron defeated Optimus and took the All Spark 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. She thawed him out while Bumblebee distracted Megatron, and the revived Prime challenged Megatron to a solo duel... Unfortunately, Megatron's link to the All Spark 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 All Spark being destroyed elsewhere, Prime could take no satisfaction in victory: this battle was won, but the war remained...

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 the Decepticons' unknown new commander was up to something bigger. Optimus has also placed the last All Spark fragment in the care of Ratchet, though he's worried exposure to Megatron may have corrupted it.

"Autobots, I am in pursuit!"

- Optimus going after Demolishor.

With the destruction of Megatron, Optimus Prime thought that he was finally, after millions of years, at peace. Little did he know that the escape of Starscream would draw dozens of new Decepticons to Earth. The desire that burns brightest in his spark is that the war will soon end. He is determined to see that end come, and so he works with his human comrades and the other Autobots to hunt the Decepticons that have come down to Earth, and destroy them one by one.



When in Shanghai along with Ironhide, Sideswipe, Skids, Mudflap and Arcee, they battle Demolishor and Optimus Prime brings Demolisher down by blasting him in the head a few times while Ironhide destroys his giant wheel. Fatally wounded, Demolisher warns them that "The Fallen shall rise again." before Optimus delivered a point-blank blast right in his head, killing him mercilessly.

Optimus and the N.E.S.T. return to Diego Garcia where the National Security Advisor questions the Autobots continued presence on Earth and proposes having the Autobots leave, which Optimus agrees to if asked.

After Ravage and the Microcons steal the All Spark shard, Optimus turns to the one ally he has that he believes can help convince the government Sam Witwicky. Optimus meets with Sam in a cemetery after sending Bumblebee to retrieve him, but Sam refuses to help, believing that he can't help and that Optimus doesn't need his help. Optimus is clearly frustrated saying that they need Sam's help more than he knows.



Later, Optimus comes to Sam, Mikaela and Leo's rescue after they're captured by the Decepticons. He then battles Megatron, Starscream and Grindor. Optimus drives into a forest, but Megatron speeds towards them in his vehicle mode from behind. Megaton fired some stray shots at Prime in his tank form before jumping onto Prime, intending to rip Prime apart while he was still in truck form. However, Optimus transformed at the last minute and punched Megatron while both robots were in mid-air. Megatron then tackled Prime, and both of them hurtled to the ground, while Sam hid on Prime's orders. Prime proceeded to beat Megatron with a tree and punched him in the back, before slashing him with one of his energon swords. This prompted Megatron to call Grindor and Starscream, who come crashing through the trees. Prime grappled with Starscream, kicking Megatron away at the same time, before holding Starscream up-side down in the air and kicking him in the head. However, the three 'cons form a bully circle around Prime, with Grindor and Starscream shooting their machine guns at Prime before Megs blasted him off his feet with his cannon. The blow sent Prime flying towards Sam, who managed to stay hidden.

Megatron questioned why Prime is sacrificing the future of the Cybertronian race over a single human life. Urged by Sam to keep fighting, however, Optimus replies "You'll never stop at one!", deployed his twin energon blades, and shouts, "I'll take you all on!" and showed the Decepticons what a Prime is. Optimus slashed at all three Decepticons, in the process cutting off Grindor's right arm and once again grappling with Starscream and using Starscream to swirl around the Decepticons by flipping over his back. Optimus tears Starscream's arm off, beats him with it (twice!!!) and then tore Grindor's head apart using his energon hooks. While calling out for Sam, Optimus was impaled from behind by Megatron and finishes off with a fusion cannon blast through the chest. Collapsing to the ground, Prime's last words are "Sam, run...".

The Autobots arrive seconds later, forcing the Decepticons to retreat. Optimus' body is airlifted to Diego Garcia and later transported to Egypt upon Sam's request, in hopes of resurrecting him with the Matrix of Leadership. He succeeds, with Optimus exclaiming both his surprise and happiness that Sam saved him. However, before Optimus is able to fully recover, The Fallen arrives, striking down Prime and the other Autobots and steals the Matrix to power the Solar Harvester.



Jetfire, who was mortally wounded, rips out his own spark and gives Optimus his parts to use to make himself more powerful to defeat The Fallen as "only a Prime can defeat The Fallen". Ordered by Ratchet, Jolt uses his electricity charged whips to fuse Jetfire's parts and the weakened Optimus. Optimus, using Jetfire's engines, flies to the top of the pyramid and tackles The Fallen. Optimus destroys the Solar Harvester with his rifle, uses Megatron's own cannon to blow half of his face off, severs his right arm and finally knocks him out of the fight with a huge blast from his jet engines. Optimus continues his fierce battle with The Fallen, managing to impale him with his own spear, rip off his face and finish him off by punching through his chest (Ow!), grabbing his spark and crushing it. Realizing they've lost, a severely damaged Megatron and Starscream retreat. Optimus sheds Jetfire's components and rejoins his companions.

Later, on the deck of an aircraft carrier, Optimus joins Sam and thanks him for saving his life to which Sam responds "You're welcome" and thanks him for believing in him. Optimus then broadcasts a message about the shared history and future of the humans and Transformers race.

"Always the bravest of us, but you could never make the hard decisions!"

- Sentinel Prime on Optimus

Optimus, now with a trailer that transforms into a weapons pack that can also acts as flight gear, travels to Chernobyl with N.E.S.T. where they retrieve a mysterious piece of metal part before coming under attack by Shockwave's Driller. Optimus grabs a sword and shield from his weapons pack and cuts loose the piece of metal parts. Shockwave emerges from the Driller to glare at Optimus before fleeing with his pet. Optimus is shocked and pissed to discover that the mysterious piece of metal is an engine part from the long-lost Ark.

The Autobots return to NEST with the part and Optimus remains in alternate mode at first as Charlotte Mearing approaches him when he's pissed. Optimus transformes and confronts Mearing about the part and the fact that they were told that everything humanity knew about the Cybertronians had been told. Mearing explained that it was kept secret from everyone except a very few people and brings in Buzz Aldrin to explain. After learning of the Ark being crashed on the moon, Optimus decides to take the Xantium to investigate the wreckage.

Optimus and Ratchet travel to the moon and enter the Ark where they find Sentinel in stasis lock with five of the pillars, including the Control Pillar. They recover the pillars and Sentinel and return to Earth with them.

Upon their return to Earth, the pillars are put into a vault under the human's control and Optimus prepares to use the Matrix of Leadership to revive Sentinel. After the arrival of Sam Witwicky, Optimus succesfully revives Sentinel who initially attacks him, before calming down after learning where they are. The two then explain to the humans about the space bridge and the threat that would be posed if the Decepticons learned of it and got the pillars.



Afterwards, Optimus takes Sentinel for a drive to show him some of the planet. Sentinel is impressed and Optimus offers him the Matrix of Leadership after lamenting what could've happened if Sentinel had led the final battle of the war. Sentinel refuses the Matrix and tells Optimus that he is now the teacher, not him.

Later, Optimus rushes back to the base after Sam discovers what the Decepticons are up to, but is too late as Sentinel has revealed his true colors, murdered Ironhide, and taken the pillars.

At the National Mall, Optimus pleads with Sentinel, who is using the space bridge to bring an army of hundreds of Decepticons to Earth, to stop. When that fails, Optimus attacks Sentinel. Sentinel pins him down and explains that he did what he did to save Cybertron before leaving, telling Optimus that he's lucky he didn't kill him and that he will one day understand.



After Sentinel makes an ultimatum to the United Nation, the Autobots are ordered expelled from the planet. Near the Xantium, Optimus meets with a deeply saddened Sam who tries to get him to stay. Optimus informs Sam that they have to go and gives some words of wisdom to his old friend about not losing faith in yourself and that the war is the humans now. Sam, under threat against his girlfriend, tries to find out the Autobots plans, subtley warning Optimus of the truth by telling him that no other human will ever know. Optimus tells him that there is no plan and tells Bumblebee to make his goodbye quick. Optimus and the other Autobots are apparently killed when the Xantium is destroyed by Starscream.

In truth, Optimus and the others abandoned the Xantium before its destruction and they head to Chicago to fight the Decepticons with the element of surprise. Optimus arrives just in time to shoot down a Decepticon fighter and save Sam, Epps and their team and orders the Wreckers to kill the pilot. After making a speech about taking the fight to the Decepticons, Sam and Bumblebee take the downed fighter to rescue Carly and succeed, killing Laserbeak in the process and hooking up with Optimus and the rest of the Autobots afterwards.



Optimus and the other Autobots head further into the city to open a way for Sam, Epps and their team to make their way to a building where they will attempt to shoot down the Control Pillar. Along the way, Shockwave and his Driller attack, separating Optimus from his trailer. After linking up with the humans in a building, Optimus heads out to retrieve his trailer, needing the weapons and flight gear it contains.

Optimus succesfully retrieves his trailer and flies in, in time to attack the Driller and save the team from death. Optimus shoots the Driller multiple times before crashing through it, breaking it in half and killing it. Optimus lands on top of a crane where an enraged Shockwave blasts him, causing him to get tangled up in cables. Optimus is spotted by the Wreckers who quickly climb up to cut him free.



The Wreckers eventually cut Optimus free and he flies back into battle, killing several Decepticons before attacking Shockwave who is fighting NEST. Optimus slashes Shockwave across the torso with bladed knuckles and rips his eye out killing him. Seeing an oportunity, Optimus uses Shockwave's cannon to blast the Control Pillar from the building its on, temporarily deactivating the space bridge that is bringing Cybertron to Earth. Optimus challenges an enraged Sentinel to battle and fights him with the other Autobots, using a battle-axe and his sword, having the upper hand until Sentinel calls upon the other Decepticons to attack them. Optimus is forced to turn his attention to the Decepticon fighters and shoot them down with his machine guns allowing Sentinel to flee, although Optimus follows him.

Optimus quickly catches up with Sentinel on a bridge and attacks him again. Optimus holds his own until Sentinel cuts off his right arm and injures his left shoulder. As Sentinel is about to kill Optimus, he is attacked by Megatron who seriously wounds Sentinel, saving Optimus' life after Carly convinced Megatron that he would be working for Sentinel not with him as Megatron wanted. At the same time, after Sam kills Dylan Gould, who reactivated the space bridge, Bumblebee and Ratchet destroy the Control Pillar, causing all the Decepticon ships to get sucked up into Cybertron which collapses upon itself and is destroyed.



Megatron asks for a truce, saying all he wants is to be in charge again and asks Optimus what he would be without him. Optimus responds with "Time to find out." and attacks Megatron. Even one-armed, Optimus is too much for Megatron and he impales him in the head with his battle-axe, rips off Megatron's head and spine, killing him. Sentinel then tries to explain to Optimus why he betrayed him, but Optimus tells Sentinel he betrayed himself and blasts Sentinel twice with Megatron's fusion cannon, killing Sentinel.



Optimus then reunites with the humans and other Autobots and declares that they will never betray Earth which is their new home with Cybertron destroyed.
