Optimus Prime started life as Optronix (Orion to his friends), Hardwired a data archivist at the Vaults. After taking note of a battle in which the Autobot leader Sentinel Prime had been defeated by Megatron, he was summoned to the Council of Ancients and informed that the Matrix had chosen him to be the next leader of the Autobots. He received the Matrix of Leadership shortly thereafter, gaining a powerful new body in the process. After dispatching a Decepticon assassination squad sent to, well, assassinate him, he ordered the Autobots to prepare to evacuate Cybertron, intending to leave the Decepticons to their own devices.

This is a weird one. Back in the late-’80s, the original TV show had ended and Marvel Comics decided to take the “transform” part of the property a step further and gave a handful of Transformers an organic, human-looking shell. Bumblebee was one of the lucky Autobots to get one. According to the storyline, the Decepticons developed the technology first, but the Autobots secretly caught wind, made their own human shells, and fooled the bad guys into thinking they were fighting mere humans, until they burst out of their shells.
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.
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.
If Optimus instead followed Prowl’s plan, he instructed his troops to transform into vehicle mode and play dead. The Decepticons, believing the Autobots’ ruse, disarmed themselves in order to carry out the Autobots’ “carcasses.” Now with the element of surprise against unarmed opponent, the Autobots Transformed and were able to easily defeat the evil robots.
The first toy in TakaraTomy's United toyline is a redeco of the War for Cybertron Deluxe Class Optimus Prime, transforming into a Cybertronic "armored truck". As has been TakaraTomy's wont of late, he now sports a metallic red paint job, with brighter pink paint applications and cooler grey parts, and features several additional paint details to those present on the Hasbro figure in the form of black chest windows and pink lines on his face mask. His rifle transforms as well, folding and plugging into the roof of the vehicle mode. The rifle can also peg into his forearms, and, in its compact configuration, can attach to his shoulders via peg holes on the backs of his front tires or stored behind his back in robot mode.
Distant Thunder was ultimately unsuccessful, but as the universe started to rip apart, a black Optimus Prime clone appeared. The Binaltech universe was split into its own separate continuity, while the original timeline was also restored, stabilizing the multiverse. The clone, friendly to the transformers, proclaimed that the Binaltech universe must be allowed to continue, as it was important to the future. Optimus Prime questioned the black doppelganger, who explained only that he carried "the Protector's" spark, but refused to reveal any more detailed information. Soon after, the clone, who was originally developed by Dr. Archeville as a weapon of evil, ejected the spark that had invaded and taken over the black figure, reverting to its original evil programming. The malevolent Nemesis Prime, no longer just a black version of Optimus, escaped.
Prime is armed with a spring-loaded missile launcher that stores on the rear of his truck mode (which becomes the backpack of his robot mode) when not in use. Like most of the weapons of the Energon line, it sports a 5mm post, allowing it to be held by most every Enegon figure, to combine with assorted other weapons and Energon weapons released in the series, and to peg into numerous compatible ports shared by many figures, like the hole in the radar of Prime's own trailer, or even conveniently placed 5mm screw holes like those of the Prime Force.
Optimus Prime appears in the Transformers live-action film series as the leader of the Autobots and one of the main protagonists. In the first three films, he 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 gains a first generation-style trailer form before changing into a 2014 Western Star 5700 Concept. 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 Axiom Nexus, General Optimus Prime found himself inducted into the Convoy, a group of Optimus Primes and their kin dedicated to safeguarding the multiverse. While the other Convoy members tended to stay in the upper reaches of Axiom Nexus, the General was able to use his unusual appearance for an Optimus Prime to venture in the Offworlder zones without suspicion, a great help to Offworlder Zone Security Administration Commander Cheetor. The General was also assisted in his new mission by his longtime scout, Sergeant Hound. General Optimus Prime profile card Sgt. Hound profile card
The second known version  ditched the triplechanging gimmick on the cab and simplified things a good bit. This Powermaster Prime has several distinct characteristics only seen in the second design, such as the wider "block head" and two faux smokestacks on top of either shoulder as opposed to one. Also, in a rather odd twist, this design features a black head and fists for both super and regular modes rather than the traditional blue. It also had yellow eyes in either mode a la the original Optimus Prime.
In 2003, Transformers: Armada launched a pivotal new era in the toy line. After several lines of toys produced by one company or the other, Hasbro and Takara united to produce what was purported to be a single, identical line of Transformers for release worldwide. In tandem with this new endeavor, Armada signaled a new continuity in its accompanying animated series and a new focus in both the show and the toys on Mini-Cons, a new faction of Transformers. The Mini-Cons were much smaller robots (not much larger than humans) who were neutral in the Autobot/Decepticon fight, but due to their incredible power and abilities, were sought by both factions.
On another plane of existence, Optimus travelled the path to the Matrix, guided by the voice of his old mentor Alpha Trion. The path led him to Grimlock, who had also been killed by Megatron; Prime rescued Grimlock from Kremzeek, the demonic eater of souls. At the gateway to the great beyond, they encountered Bludgeon, who announced that only those who bore the "key to Vector Stigmata" may pass through. Prime realized that the wounds on his body form the key, but the angel insisted that these would grant Prime access. Prime took Grimlock's sword and bestowed the key on Grimlock, allowing the former Autobot King to ascend into the Matrix while Prime stayed behind. Transformers vs. G.I. Joe #12
A larger version of Prime, with Advanced Automorph technology and a more complex transformation procedure. Has two sets of electronic sounds and lights that activate when the head pops up or when you press a button on the roof (in truck mode), and a single projectile weapon that can swing over the toy's right hand. Unlike Megatron (whose head is fixed) and Brawl (whose head is connected with a ball joint), Prime's head is limited to side movement due to the circuitry on his LED eyes. This figure has a folding cannon and a firing missile. With this figure standing nine inches tall and Optimus being 28 feet (336 inches) tall, the toy is about 1/37 scale.
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.
