The paint deco is... unfocused, to say the least. In vehicle mode, the grill, headlights, bumps (thus his feet) are painted silver, yet the red in the small Autobot insignia has been removed. There is silver paint on the fuel tanks (toy battery cover), but not on the other tool boxes and equipment in the same location. There is also silver paint on all 6 wheel rims, the air cleaners and the windscreen visor. In robot mode the silver paint is mainly located on his thighs and crotch, though in order to save on costs, the dark blue and gold paint on his thighs and knee joints have been sacrificed.
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. 
A giant-sized transforming Optimus Prime figure is set to be released for the third film. The set comes with a Leader Class-sized Optimus Prime figure and a trailer that transforms into his Omega Combat Armor - both of which combine to form Prime's Ultimate mode. This set will be released on August 1st, 2011, a month after the film's premiere.
The original Optimus Prime toy, as well as the Diaclone Battle Convoy toy that it was based based upon, transforms into a late 1970s red Freightliner FL86 Cab-over-Engine triple-axle semi trailer truck. The truck mode features rubber tires, and the cab is partially constructed of die cast metal. The windscreen section can open to reveal ultimately-unused seats that were originally designed for Diaclone's driver figures.
A large, non-transforming toy that features light & sound effects and voice tracks by Peter Cullen. The figure itself is a representation of Optimus Prime combined with Jetfire's parts - only designed for younger children. A lever on his waist extends his wings, and flying sounds are emitted when he is moved around off the ground. The Power Bots line replaces the 2007 Cyber Stompin' line of the first film.
A re-release of the Leader Class figure from the Revenge of the Fallen line, but with retractable forearm hooks (as seen in his battle with Grindor) in place of the blades. In addition, the figure comes with the unmasked head of Buster Optimus Prime and is painted with battle damage effects. A recording of Peter Cullen saying, "We must stop the Decepticons!" is played when his chest is pushed upward via a lever on his waist. Fans have nicknamed this figure "Battle Hooks Optimus Prime" to distinguish it from the other Prime figures.
For many, it may seems that the advent of licensed sets3 correlates with the perceived increase in prices. The 1990s and before were a nostalgic heyday of affordable LEGO sets. This is not quite true. Below is a chart that compares the price per piece of licensed sets and unlicensed sets starting in 1999. 1999 is the first year that LEGO had major licensed themes.
Based upon the "Protoform" (Cybertronian) appearances of the Transformers in the Movie, Protoform Optimus Prime transforms into his "entry" mode. This mode somewhat resembles a cybertronic truck, with false wheels sculpted onto the sides, and Optimus Prime's trademark windows in front. A flame decoration piece fits to the back of the "vehicle", creating the illusion of a flaming comet's tail. The bottom of the vehicle has small wheels to roll the toy across smooth surfaces. Oddly, it has NO automorph gimmick at all, a feature most main-line figures have.
The protoform mode consists of eight pieces of metallic blue plastic that plug into the arms, chest, pelvis and legs of the figure. With these pieces attached, the figure can be manipulated in a manner that might charitably be called "transformation" into his meteor-like "entry mode," accomplished by doing little more than tucking the head out of sight and folding the chest back. This blue-and-grey lump can be mounted on a three-piece stand that comes with the figure, allowing you to display it in mid-plummet. Optimus Prime's Earth mode, meanwhile, is made up of many armor pieces (including a particularly large backpack) that form a rather kibbly robot mode, which can then transform into a truck approximating a Peterbilt 379. We would go into what an abominable, unintuitive, parts-massaging mess this transformation is, but we wouldn't want to fill up the rest of the page.
This Optimus Prime is a redeco of the figure above, featuring red wheels and various Tech Spec-sque patterns on the legs & chest which can be decoded with their transparent red weapons, which is molded in a sprue similar to the ones used for the Arms Microns kits & Robots in Disguise (2015) Mini-Con figures. He can use any weapons included in this set, although his primary weapon is an axe.
Only available at ToysЯUs, this Optimus Prime is a redeco of the Classics figure. He features a cartoon/toy accurate deco on his truck/robot parts, and vacuum-metallized upper legs & front grille to evoke his original Generation 1 toy. Like every Classics Optimus Prime mold, he still features all of his accessories. This Optimus was packaged along with the redecoed Age of Extinction Optimus Prime.
LEGO has changed a lot in its history. It started as a wooden toy company before it discovered the benefits of molded plastic. Since the advent of the brick, we have been able to build everything from houses, to spaceships, to working robots. The increased detail and wider product line has allowed for the blossoming of the idea of LEGO as an art medium7. LEGO bricks walk the line between giving people more pieces that can be used to add detail and restricting the pieces to inspire creativity. There is a balance that can be seen through the amazing works, both large and small, that can be done with a bit of patience and an eye for plastic.
Like the previous Prime, it is loaded with features, though it ditches the first movie's Automorphing for the new Mech Alive gimmick. When a grey tab on his midriff is pressed, Prime's entire pectoral region "flexes", lights in his chest and eyes glow, and he declares "I am Optimus Prime" in Peter Cullen's voice. For the European release of the figure, to get past the language barrier, the Cullen sound clip is abbreviated to just "Optimus Prime"; in some regions, including Quebec and the UK (but only after a month or two), both versions were made available. A transformation sound effect activates when his torso is transformed, and once Prime is in truck mode, an almost unnoticeable button (a small square located beside the screw for the battery compartment, undocumented in his instructions) is revealed, which activates engine-idling noises.
Came with the Mini-Con Sparkplug. Could combine with Armada Jetfire (and its repaints) and/or Armada Overload (and its repaints). The trailer could convert into a base for Mini-Cons. In Japan a gold chrome edition of this toy was released as a Lucky Draw special. With its trailer the vehicle mode of this toy bears a great resemblance to G1 Star Convoy. According to the Armada video game Armada Optimus Prime is supposed to be 22 feet 10 inches tall (696 cm tall) and the toy is 17.5 cm tall. So that's a scale of 1:40.
In the United Kingdom, this Optimus Prime was released as an Argos exclusive along with several other sets branded as part of the Reveal the Shield subline imprint. His United States release was initially claimed to be exclusive to Target by online retailers from Asia, but even though the other Reveal the Shield products eventually became available at Target, Voyager Class Optimus Prime was released as a Toys"R"Us exclusive in the United States instead, complete with a "Toys"R"Us exclusive" sticker. Also, both his United States and Asian releases lack the "Reveal the Shield" logo the United Kingdom release has (but still feature the "Reveal hidden images" call-out).
This is an arbitrary line but it is a line that needed to be drawn. There have been many promotional sets over the years which have very few pieces but carry a higher price because of their promotional status. These can range from keychains to individual minifigs to seasonal items. They are not representative of the typical price of a LEGO brick and therefore should not be included in the evaluation.
In late 2014, twelve Kreons were sold through TakaraTomy's "TakaraTomy A.R.T.S" Gacha capsule-toy machines in Japan. Thankfully for the rest of the world, these Kreons are all basically identical to previously-released ones in the Hasbro lines. The Gacha release of Optimus Prime is basically the base Custom Kreon Optimus using his clear-plastic helmet and carrying the small ray pistol, lacking his leg-wheels, smokestacks and backpack (and of course all those other parts and accessories).
The Hasbro website explains it best: "The rogue DARK NINJA MASTER was exiled to a cave beneath Arashikage Mountain for betraying the ninja clans. After finding the Moon's Blood, a mystical stone of great power, he was able to channel the energy of dead ninjas, making him almost unstoppable. Seeking revenge, he has emerged from his subterranean prison to destroy all ninjas. Only two people can stop him: STORM SHADOW and SNAKE EYES. The two adversaries must join forces, for only by working together will they be strong enough to defeat this evil super-ninja."
Generation 2 Optimus Prime comes with all his original accessories, as well as two major new play features. To increase his arsenal, he is armed with a pair of black missile launchers that fit in his fists and fire red spring-loaded missiles; these launchers were retooled from the G.I. Joe figure Barricade. Secondly, he comes with an electronic "sound and lights module" that can either plug into the front of the trailer (where it resembles the air conditioners used on refrigerated trailers), or hook onto Optimus's back in robot mode (via a new slot sculpted into the cab robot). Unfortunately, the soundbox is heavy enough that doing so can easily overpower Prime's hip joints, causing him to topple backward. The soundbox features a large, vacuum metalized Autobot symbol on its front, and three grey buttons which trigger two flashing red LEDs on either side of the module, and a trio of sound effects: a truck engine noise, a laser gun sound effect and a garbled voice that said "I am Optimus Prime!". The module also features ports on either side into which the missile launchers can peg.
