Marissa and Prime are now on the run from the EDC and are also frequently attacked by the mysterious "Legion" Transformers. When faced with such foes, Marissa unleashes her "Kiss Player" ability by kissing Prime, fusing with him once again, increasing his power so that he can best their opponents. Prime is armed with the Surf Blade, a weapon formed out of Marissa's surfboard, wielded expertly thanks to the knife skills Marissa passes on to him when they merge.
A golden-chrome redeco of Cybertron Metroplex was offered as a contest prize in the December 2005 issue of TV Magazine, and came with an equally blinged-out Legends/EZ Collection Optimus Prime figure. Fifteen of this set were available as prizes in the initial contest; a single Metroplex was later offered as one of many prizes in a Takara website contest, but this version came only with the standard metallic paint version of Prime.
For some reason: unlike the stock photos (pictured from the right), This Custom Kreon had a slight QC issue to the opaque and transparent helmets: One had two sides sculpted, while the other one has the small flat square sculpt (similar to the details on Hound's helmet) on the right side. Several samples had two different "variants": One with the perfect transparent helmet & a differently-sculpted opaque helmet, while the other one has the opposite. However: later releases fixes the problem by a running change.
A black and red version of the First Edition deluxe Optimus Prime could be seen in the San Diego Comic-Con 2011 Transformers slide show, inside a mock-up of the wearable Matrix of Leadership package done for the convention that year. This figure was presumably a test-shot, as it seems to share plastic colors with Generations Sky Shadow (who was, coincidentally, first revealed at that same Comic-Con).
The second Nightwatch Optimus Prime was released as part of the "AllSpark Power" second half of the Movie line. He is similar to the UK version of Nightwatch Prime, replacing most of his red and blue with different shades of blue and black, retaining his resemblance to Diaclone Powered Convoy in most respects. However, the subdued black and copper on the first Nightwatch Prime have been replaced with gold and a very bright blue, to signify the All Spark energy affecting the Transformers.
Part of the third wave of Prime Cyberverse Commander Class toys, Nightwatch Optimus Prime is a redeco of Series 2 Cyberverse Optimus Prime, using the faceplate-less head sculpt that is gang-molded with the original head. His blue plastic is now gray, his smokestacks and thighs are left unpainted, he loses the Autobot insignia on his right forearm/door, and he gains yellow paint highlights for his eyes and lights, along with various other minor deco differences. Instead of the original release's cannons, he now comes with a pair of swords, which each have a pair of 3mm posts for wielding/mounting.
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).
This Japanese-exclusive black-and-gold redeco of First Edition Voyager Class Optimus Prime was available exclusively at the fourteen stores taking part in the Cybertron Satellite promotion. It depicts Prime coated in an alloy reverse-engineered by Ratchet from MECH equipment that protects Optimus against Dark Energon and other techno-biological hazards.
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.
Prime was perpetually at the forefront of the action throughout the early years of the war on Earth, usually confronting Megatron, though in some rare instances, such as against the Insecticon-controlled Decepticons or the Combaticons, teaming up with him for the greater good. He has suffered his fair share of battlefield scrapes, almost meeting his end when his vital cosmotron component was critically damaged by the Decepticon jets and when Laserbeak had his body disassembled and turned into Decepticon trophies, such as a pet "alligaticon" and a defense laser.
Though the figure does a much better job of conveying the on-screen character model than the ROTF Leader Class mold did, there are still a few inaccuracies—most notably the forearm and shoulder pad designs and the head/torso proportions. The final product also lacks certain paint details visible in stock and packaging imagery, such as the blue rings on his feet and the gold on his pelvis. It should be noted that this mold does not combine with Jetfire.
The final scraping was done in Python. A long time ago when I started it, the prototype was in a language called DM or byond. This is a language created for the purpose of writing 2d online rpgs. It was my first language and was easy to pick up but this was pushing its limits a bit. I actually ran the first scrapping on my other post (the Politics one) in this language. The results were not what I used in the article but it was a good proof of concept.
The third version  would quite possibly have been the most gimmick loaded Transformer in the history of the line, simultaneously being a Powermaster, Headmaster, and Triple Changer. The Headmaster also would have been a Triple Changer, turning into a sort of armored four-wheeled rover (Roller II?) and robot as well as a rather silly looking Optimus Prime head with four vertically aligned wheels jutting off the sides. It seems that when the extra Headmaster gimmick was scrapped, the super mode head remained separate rather than being reintegrated into the trailer hitch such as on the earliest design. Notably, the body of this design is extremely close to the final design.
Take note that the leg construction (thigh parts with legs consists of rear wheels/fifth wheel hitch & engine compartment/flip out legs combination) can become loose after a long time of play due to being used with transformation. Also, the legs did not seem to securely connect due to the hitch's shallow holes & the front half of the legs' small pegs. Also, attaching weapons with 3mm posts on the Battle Cannons' holes can cause some stress marks.
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.
Prime's cab and trailer can also combine to form a super robot mode. Transforming the cab into the torso portion sends the transformation command to the trailer, which raises itself up off the ground to become a pair of immobile, statuesque legs (as long as you're not playing with it on carpet), and when the pair are connected, the super-robot head pops up with a metallic shriek sound effect. Pressing the Autobot symbol on the figure's chest activates a pulsing laser sound effect, and the small grey button on his right shoulder illuminates his fist with a red LED, which can illuminate either of his guns, as well as the Star Saber sword (the Star Saber was specifically cast in clear plastic for this purpose, but in practice, the light failed to carry even halfway up the blade).
Optimus Prime is another redeco of Revenge of the Fallen Legends Class Optimus Prime, features gunmetal-stque grey plastic, and his paint operations being similar to the first Revenge of the Fallen Legends Class toy. He is also packaged with Grimlock, himself a redeco of none other than Energon Cruellock. Like other Legion-themed product, he is exclusive to Walmart in the US and Asda in the UK.
Originally, Optimus Prime was created as the leader of the Autobots, though it is unknown how he was created or his origins. In a possible future, Megatron was threatened by the existence of the Aerialbots and had Shockwave build a time machine to send them back in time to get rid of them. However, he only ended up changing history for the better. In the revised timeline, Optimus Prime began his life as a robot named Orion Pax, a mostly defenseless dock worker during the Golden Age of Cybertron nine million years ago, with a girlfriend named Ariel and a best friend named Dion. During this time, a new breed of robot with new flight capabilities appeared on the planet that Orion idolized. When Megatron, the leader of the new group of robots, approached him with inquiries about using one of the dock warehouses, Orion was swayed by Megatron. Both Orion and Ariel were severely wounded when Megatron and his forces attacked in order to claim the energy stored there. Searching for someone to help them, the time-displaced Aerialbots took Orion and Ariel to the ancient Autobot, Alpha Trion, who used them as the first subjects for the new reconstruction process he had developed involving rebuilding the frail Autobot frames into more battle-hardy configurations.
