Prime: First Edition Matrix of Leadership Optimus Prime converts from robot mode to his truck mode. He comes with a gun than he can wield with his hands, as well as peg onto his hitch in vehicle mode, with different pegs for either configuration. Similar to a previous Optimus Prime toy, he features some faux-kibble in the form of his actual windshield chest being covered by sculpted panels featuring his characteristic windshield-chest. His arms are slightly longer than his original design's arms.
Naturally, Optimus Prime got the biggest of the sets in the first year of Kre-O. The set can be built into a large long-nose tractor-trailer rig with a removable "sleeper" cab that hides a computer station, and a trailer that can carry the set's two motorcycles or open up to carry larger car builds. The robot mode build includes a huge Optimus, based largely on the live-action movie Optimus, though with a head based almost directly on the Classics Voyager Optimus. He is armed with a distressingly plain brick that fires pressure-launched missiles (aka his smokestacks). Most of the leftover parts in robot mode become a "headquarters" which is mostly just a random assemblage of mismatched-color panels and a pair of barricades. Both main builds leave numerous parts unused if you go expressly by the instructions, but hey, it's a building kit, surely you can find someplace to apply most of them.
The TakaraTomy version of Premium Series Optimus Prime has a considerably different deco from Hasbro's release. Similar to the unique chrome Optimus Prime, Optimus Prime Battle Mode features vacuum-metallized parts for nearly all of the silver truck parts, for a greater resemblance to the polished chrome on the real prop trucks. Unfortunately, as his feet are the front fenders and grill, this will likely lead to chipping. In robot mode, he retains several decos that were removed from Hasbro's Premium Optimus Prime for cost reasons, such as the blue and gold decos on his thighs. Finally, the flip-out energy sword is coloured gold to reflect its "powered up" appearance.
Just as Marvel Comics produced a companion comic to the original Transformers toyline that differed from its animated counterpart, so did Dreamwave produce a comic to go along with the Transformers: Armada and Energon lines that owed little to their animated fellows. This incarnation of Optimus Prime, however, is not particularly different from his animated counterpart in personality.
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).
Optimus Prime was given the Matrix by Primus himself, and used to be friends with Megatron. Prowl is his closest friend and Ratchet is his oldest. Searching for Energon, the Autobots landed on Earth, but were followed by the Decepticons. With the help of their human allies, they bested their foes, and knowing they would return, decided to stay and wait to defend the planet once more. Optimus Prime was proud to be an Autobot. I Am Optimus Prime
The bio for the Botcon 2015 version of Megatron reveals that he comes from an alternate reality where Megatron achieved victory during events similar to Dark of the Moon and killed both Optimus and Sentinel Prime. However, Rodimus Prime then arose to challenge him, facing him in a battle that Megatron ultimately chose to flee, resulting in him ending up in the Axiom Nexus.
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.
