In Transformers: The Last Knight, he is brother-in-arms with Bumblebee who he fought alongside with to foil the Nazi Party in World War 2. He speaks with a thick French accent due to being stuck in France for so long, much to his own embarrassment. He wields a special gun which can briefly slow down time. He is also the only Transformer who is shown to speak in vehicle mode. 
He comes with a shield with a fold-out handle, allowing Optimus to hold onto it with either hand in robot mode. It has a simple transformation gimmick for vehicle mode which is activated by pressing a button at the top of the shield, causing the sides to spring outwards. In vehicle mode, the shield can be laid flat across the bed of the truck, attaching via a post on the back onto the truck’s trailer hitch. Alternatively, the bumpers on the shield can be rotated outwards, and the front can be bent down in order to form a new front end and hood for "battle vehicle mode", resembling the Stealth Force vehicle modes seen in Dark of the Moon.
Using their network of human allies, the Autobots tracked the Decepticons to Stanley Lake. When Optimus learned that the Decepticons had taken over the hydro-plant, he lured them out into the valley in front of the dam so that Jazz and the humans could flood the valley, washing the Decepticons away. Menace at the Dam Starscream attempted to defect as part of a ploy to get a spy into the Autobots' midst, but Optimus wasn't fooled at all. He and his men concocted a false plan which they shared with Starscream, and while the Decepticons were subsequently on a wild goose chase, Optimus's team smashed the Decepticon base flat. As they let Starscream go, Optimus couldn't help mocking him. Espionage!!!!!
Tiny Turbo Changers Optimus Prime is a small, stumpy, soft-plastic blind-bagged mini-figure that changes from robot to a licensed Western Star 5700 OP Truck with just a few simple steps. He features ball-jointed shoulders and hands that are compatible with Cyberverse weapons and other 3mm post accessories. Like all Tiny Turbo Changers, his vehicle-mode tires do not spin, sorry.
Optimus Prime is the leader of the main group of Autobots in the iteration of the Transformers franchise primarily marked by the 2010 computer animated series Transformers: Prime on The Hub. Optimus Prime was created as the last of the Thirteen Primes, the first generation of Transformers, each created directly by Primus as a band of unique warriors to combat and defeat Unicron. Upon his creation, Optimus united the Thirteen by his greeting All are one. While all of the other members of the Thirteen each possessed unique abilities and artifacts, Optimus wielded no special powers or weapons. It was only through his vision and courage that allowed the Thirteen to finally defeat Unicron. Reborn through the Well of All Sparks, Orion Pax became Optimus Prime, a veteran military commander and second in command who wields an ion blaster and a double bladed energon axe. He became the leader of the Autobots after Sentinel Zeta Prime fell in battle, but is not certain he wants the responsibility.
Like many other modern toys, Optimus was designed with an alternate head sculpt (based on the mouthplate-less face as seen on the show) intended for a later retool, which was gang-molded with the original head. At least one specimen sporting the mouthplate-less head has been found at retail, although since this occurrence has seemingly been limited to an isolated incident, it can be assumed to be a manufacturing error rather than a genuine variant. The mouthplate-less head sculpt was eventually used officially for a later-wave redeco, Nightwatch Optimus Prime (see below).
Hot Rod would appear in the UK Marvel comic issue #234, "Prime's Rib!" This story is set in the near future, 1995, where Optimus Prime, Jazz and Hot Rod introduced the latest Autobot, Arcee, to the human feminists. She was met with displeasure by the humans, being called a token female and disliked for her pink color. They were then attacked by Shockwave, Fangry, Horri-Bull and Squeezeplay, who thought the Autobots would be unveiling a new weapon. The Autobots fought off the Decepticons, who escaped, but nothing seemed to please the human feminists.
Virtually every toy in this list has a scannable insignia sticker on it. For Hasbro releases, it temporarily unlocks that toy as a playable character in the Robots in Disguise mobile game, and can only be scanned once per day. TakaraTomy releases simply check that off on their mobile app's collection list. It's honestly quicker and less redundant to say which toys don't have this feature. Meanwhile, scanning the Combiner Force toys' insignia stickers gives the player Tickets, which can be spent by giving them to Cryostase via the main map menu.
In our list of things you didn’t know about Optimus Prime, we learned that the live action version of Optimus was based on actor Liam Neeson. It turns out Michael Bay likes to base his Transformers on real actors, because it’s been revealed that Bumblebee’s character movements are based on Michael J. Fox-- but not just regular old Michael J. Fox; we’re specifically talking about Marty McFly in the Back to the Future movies.
On the battlefield, there are few who rival Optimus Prime's prowess. He is easily the strongest of any Autobot his size, and his ion blaster and energon-axe are deadly weapons. He would sacrifice his life to protect his fellow Autobots or those under their care and does so on a regular basis. His compassion for other sentient beings is his only real weakness, and one the Decepticons have taken advantage of time and again... though it's also the source of his strength!
If Optimus ordered his troops to come to the humans’ aid, they found themselves taking part in a struggle in futility, as the entire town was near-weightless, meaning they couldn’t put the humans anywhere where they wouldn’t float away once more. Then, the Autobots heard Decepticons approaching. Helpless in their current position, the Autobots were quickly eradicated by the Decepticons.
A redeco/new-head retool of the Rescue Bots Hoist the Tow-bot figure, Optimus Prime transforms from robot into a tow truck. Pulling the tow truck's hook up converts him back into a robot. The panel on the top of the cab has been remolded with additional truck detail in place of the Rescue Bots logo on Hoist, while the Rescue Bots insignia on his torso is unpainted.
His main gimmicks, however, are the two large, blue-and-white mini-guns hidden in his back/hood, which can deploy and "weaponize" either mode. When deployed, the mini-guns swing out from his back/hood and spin, while a red LED inside his torso lights up briefly. The mini-guns swing down to the sides of his head in robot mode, and can also be deployed in vehicle mode when one manually opens the grille. Pushing down on the red lever on the center his torso (in either mode) briefly lights up the LED again and swings the mini-guns back into their hiding places.
Not depicted in the instructions or stock photos, Roller can attach to Prime in vehicle mode via two tabs on the vehicle front which slot into two corresponding slots on Prime's feet. Another undocumented feature is that the butt of the Ion Blaster can be inserted between the barrels of Roller's weapon mode to form a longer weapon. Also not shown in the instructions but depicted on the stock photo on the card-back is that Prime's shoulderpads can be rotated up; the intended positioning for this is notched, although you can position them at other angles.
One peaceful day, Optimus decided it was too quiet, and sent Bumblebee and Mirage to find out what the Decepticons were up to. Sure enough, the Decepticons were looking for a factory, so Optimus had Mirage create a holographic factory as a trick, and ambushed the Decepticons. Optimus himself hurled Megatron into orbit. Decepticon Patrol Optimus and his Autobots rescued Sparkplug and Buster Witwicky when the pair were captured by Decepticons, and afterwards Prime was amazed when Sparkplug repaired Wheeljack and Prowl. After Bumblebee and Hound discovered that the Decepticons were attacking Hoover Dam, Optimus and his team defeated them. The Deadly Fuel Shortage
This gold vacuum metallized (save for his black joints, which they were made out of unpaintable plastic) Protoform Optimus Prime figure was featured as a Lucky Draw giveaway (along side similarly gold vac-metal versions of Voyager class Optimus Prime and Protoform Starscream) in the December 2007 issue of TV Magazine. Released in 2008, only 5 pieces were made, making it one of the rarest Lucky Draw figures; the images at right represent the only known photographs of it.
