For Transformers: Age of Extinction, Optimus Prime initially transforms into a rusty 1973 Marmon semi cab-over truck and later on a new alternate mode in a blue and red Western Star 5700 Custom semi-truck. After humanity turns on all Transformers, regardless of faction, Optimus and the other Autobots go into hiding. Eventually, they find themselves being hunted by a rogue organization called Cemetery Wind. Optimus is severely injured in a trap set by the group, while many of the other Autobots, including Ratchet and Leadfoot, are slain. An inventor, Cade Yeager, comes to Prime's aid and helps restore his health. After uniting with a small band of Autobots, Optimus faces Lockdown, a ruthless bounty hunter allied with the humans, and KSI, an organization that produces man-made Transformers. Optimus is captured by Lockdown, but the Autobots rescue him. Optimus is quickly losing faith in humanity, but at the urging of Cade, chooses to stay and fight a resurrected Megatron and his new army. Prime awakens the ancient Dinobots, and rides a newly tamed Grimlock into battle through Hong Kong. He kills Lockdown and Harold Attinger at the film's climax as revenge for killing many of his friends, including Ratchet and Leadfoot. At the end of the film, he leaves Earth and flies off into deep space, seeking to find out the truth about his mysterious Creators.
Optimus was able to rally Autobot factions from across Cybertron to the cause and launch an all-out attack on Shockwave's fortress. He headed the assault himself, but broke rank when he saw the image of Shockwave blasting Ultra Magnus upon one of the many monitor screens planted around the Decepticon's headquarters. Optimus charged in to confront Shockwave, beating down all opposition along the way. Coming upon Shockwave's throne room, Prime was greeted by Ultra Magnus, who pointed him towards a secret passage through which Shockwave had absconded. Leaving his wounded brother to rest, Optimus barged into Shockwave's secret chambers, only to be overpowered and have the Matrix ripped from his chest. With it, Shockwave was finally able to activate Vector Sigma. Countdown to Extinction Stalling, Prime listened as Shockwave recounted the history of Cybertron, and eventually Ultra Magnus arrived, having recovered, to attack and defeat Shockwave. Prime and Grimlock helped him escape from the fortress as it crumbled to the ground. With Shockwave's defeat, the Autobots would now be able to start rebuilding Cybertron towards true peace... but Optimus remained troubled by Shockwave's motives; he recognized that Shockwave would not be urged to action by mere fancy. Optimus pondered what greater threat awaited Cybertron for Shockwave to so thoroughly plan for its arrival. Revelation The injuries Prime took in this conflict necessitated a prolonged restoration period in stasis. Both he and Ultra Magnus were tended to by Perceptor and Hoist as they recuperated. Generation 1 #0 Though Magnus recovered in due course, Optimus's systems had received a more severe shock due to the Matrix being forcefully removed from his frame. Thus, he needed additional time spent in recovery before he could reboot. Black Sunshine
As the two Titans battled, Optimus found Megatron watching the fight and demanded he assist them, but Megatron refused. When Trypticon swallowed the Enigma of Combination and took control of the Combiners, Optimus attempted to attack them as a distraction, but he was caught and the Combiners attempted to pull him apart. Optimus managed to break free of his captors and was further saved by the timely arrival of Megatron. Against Optimus's wishes, Perceptor returned and tricked Trypticon into swallowing the Matrix. Consumed However, this ultimately proved successful, and Trypticon released all that he had swallowed during the conflict before falling inert once again. The relief was short-lived, though, as Megatronus suddenly appeared before them, proving Optimus's fears. Optimus and Maximus attempted to surprise attack Megatronus, but he brushed off their blows and fired a beam through Optimus's chest, killing the Autobot once more. All Things Must Pass
The character Optimus Prime appears in the live action films Transformers, Transformers: Revenge of the Fallen, and Transformers: Dark of the Moon as the leader of the Autobots and one of the main protagonists of the three films. In these movies, Optimus Prime is able to transform into a conventional Peterbilt 379 cab, rather than the cab over design of his original Generation 1 body. In Transformers: Dark of the Moon, he regains his first generation trailer. Also straying from the G1 design, Prime's vehicle mode is now decorated with red flames painted onto a blue body à la Rodimus Prime, his Generation 1 successor. The reason for the change was due to Director Michael Bay's decree that mass displacement does not occur when they transform, requiring Optimus's vehicle form to have more mass to achieve the desired size in his robot form.
In robot mode, like Combat Hero Prime, the bottom of the truck became his familiar windowed chest based upon the original Optimus Prime toy. His main gimmick was light up LED headlights, and a lightpipe in the bottom of his right fist, illuminated by an LED in his right forearm, that would illuminate his clear sword or his double-barreled rifle if they were used in that hand. All three LEDs were activated simultaneously by pressing the sunroof-like depression on the roof of the truck.
After many battles on Earth, Optimus died by standing purposefully in the path of the Hydra-Cannon built by Megatron from the three Mini-Con weapons, the Star Saber, the Skyboom Shield, and the Requiem Blaster. He managed to partially reflect the beam, damaging the Hydra-Cannon. It was the Mini-Cons themselves, however, who resurrected him, entering the Matrix and reconstructing a new body for him. Subsequently, Unicron forced Optimus to face the dark part of his soul and that, on some level, he enjoyed the thrill of combat. Following Unicron's defeat, Optimus's denial was sorely tested as Galvatron, an upgraded Megatron, forced him into one final furious battle. The battle ended when Starscream sacrificed himself to end the circle of hate that powered Unicron. Floating through space, Optimus found the Matrix, but said he did not deserve it. Before beginning the battle with Galvatron, he was upgraded by the minicons. His red torso turned black and he was able to battle Galvatron one on one.
Released as part of a new line called Transformers: Tribute, Orion Pax is a redeco of Titans Return Sergeant Kup, and transforms from a red-and-blue Cybertronic pickup truck which is also an homage to Generation 1 Crosshairs's vehicle mode G1 Optimus's e-HOBBY toy. His Titan Master, retooled from Flintlock, features a new face that is based on the Thrilling 30 Orion Pax toy. As a redeco of the Kup mold, Orion Pax still suffers the leg panel misassembly.
In the two-part episode "Megatron Rising", Optimus loses his composure over the recent numerous Decepticon attacks coupled with the fact that Prowl had secretly placed the Dinobots on an island off the coast of Detroit instead of destroying them. He has Ratchet confiscate the Allspark key from Sari, which he loses when he is ambushed by Blitzwing. Optimus also fails to stop a newly resurrected Megatron from acquiring the Allspark. He defeats Megatron by overloading the Allspark in his chest with Sari's key. In the process, the Allspark shatters into countless pieces, scattering all across Detroit.
When the legendary Energon Cube was lost to the reaches of space, Optimus Prime led a small team of Autobots in pursuit of it. The giant energy source crashed on Earth in the Japanese town of Hoshinochō, where it shattered into fragments that were scattered far and wide. Prime and the other Autobots set up a subterranean base below the Cube's impact crater and began their search for the shards, taking the forms of local vehicles to hide their activities. Despite their attempts at remaining unseen, glimpses of the Autobots only magnified the reputation the crash of the Cube (believed by humans to be a meteor) had given Hoshinochō: that of a hotbed of rumored alien and UFO activity, Japan's answer to America's Roswell. Kingdom of Giants
The figure was re-released in Hasbro's Asian markets in 2012, with no known changes to the figure itself but several modifications to the packaging that makes it easy to tell the two releases apart: The flap containing the package art is omitted entirely, the "Commemorative Series II" label is missing, the age recommendation and safety warning labels, the "Changes from double tractor trailer to battle station to super robot!" call-out and the name of the toy have all been shuffled around (with the words "battle" and "super" being omitted in the process), and most notably, the toy is no longer named "Powermaster Optimus Prime with Apex Armor", but simply "Optimus Prime", with Apex Bomber's existence no longer acknowledged anywhere on the packaging.
The Heroes of Cybertron PVC figurine line is an adaptation by Hasbro of Takara's own Super Figure Collection line. The main differences between the two lines is that Hasbro cast Autobot and Decepticon figures in clear blue or clear red PVC respectively, then completely painted the figurines. This allowed the eyes to 'glow' when placed in front of the light source.
