Optimus Prime also appears in the text-based fiction Dungeons & Dinobots. He commands the Autobots to attack the Arch-Ayr fuel dump. The attack is thwarted when the main Decepticon forces are augmented by the Mayhem Suppression Squad. When Wheeljack attacks both the Autobots and Decepticons with a massive force of drone Dinobots, Optimus offers to allow the outcast Autobot scientist to rejoin the Autobot ranks if the Dinobots destroy the Decepticons. The Dinobots prove unstable and go on a rampage, attacking everyone, including each other. Optimus punishes Wheeljack by having Ratchet painfully reformat him for Earth mode and assigning him to the Ark repair crew on the advice of Side Burn. He punishes Blurr for allowing his heroic Decepticon cousin, Crasher, part of the Mayhem Suppression Squad, to live. When Grimlock returns to the Autobots, Optimus lets him live because the Dinobot has gained useful intelligence and helps in work on the Ark.
Millions of years later, Optimus was one of the thirty-five Autobots rebuilt into modern machines by the ship"s computer. Some time later, Jazz reported that he had spotted Decepticon activity at a nearby construction site. Optimus decided to take a proactive angle to their war with the Decepticons, and led the entirety of his troops to the Decepticon base. Once there, they found themselves allowed in by Megatron, feigning a friendly demeanor. Not fooled by Megatron's claims that he was making an honest living heading a construction company, Optimus engaged the evil robots in combat, before being blasted out of the Decepticon base. Optimus and his troops were sent tumbling down the cliffside beneath their feet. The Autobots suffered only minor damage from the fall, and after getting patched up, moved out once more to stop Megatron's plan, now well under way. Megatron was holding millions of humans hostage in a bid to get the Earth to surrender unconditionally to the Decepticons.
Exclusive to Walmart, this Deluxe Class Optimus Prime is an all-new mold, close in scale to Voyager Class Megatron. He has a high range of motion, with ball jointed shoulders and hips, swivels at the neck, knees, and feet, and double swivels in the elbows. As a result of the transformation process, he can also rotate at the waist, though this is hindered considerably by his "backpack" kibble. This can be remedied by pointing the truck nose downward, as it is in the packaging. Optimus Prime also features the spring loaded "Automorph" feature in his head, if the truck kibble pushes the small grey switch from his back before splitting the chest into half.
The box seems to have been created rather hastily from the Japanese original. It is roughly identical to the Tomy release, but with the Japanese text edited out... mostly. Random Japanese text remains floating in space on the top of the back panel and underneath the "Jetwing Optimus Prime" name on the front. Curiously, the left flap has been rewritten to eliminate mention of NEST and the jetpack's ability to detach, while the right flap has been (badly) edited to remove all mentions of MechTech.
The TakaraTomy version, part of the seventh wave of Japanese Prime toys, is dubbed Arms Master Optimus, uses darker, metallic plastics, casts the backs of his thighs in metallic red, replaces his metallic silver paint with glossy gray, and replaces a few of his paint operations with customer-applied foil stickers, such as his insignias, shins, headlamps, the tiny yellow lights on his torso, and the blue deco on his truck panel sides. He has also been retooled with additional 5mm pegs for his thighs, roof, and lower backpack, as well as ports for his forearms, shoulders, smokestacks, fuel tanks, and roof. Instead of the rifle, he comes with a very large Matrix which can tab onto his chest as armor or mount onto the back of the truck cab, with the Matrix also being covered in 5mm posts and holes so that Arms Microns can be attached to it. He additionally comes with a clear-blue "Shining" version of the Arms Micron, R.A., who can combine with the Matrix to form the colossal Matrix Saber.
Prime comes with a unique Cyber Key, designed after the twin-handled appearance of the Matrix of Leadership, bearing the code l8p3. When inserted into the cannon that the rifle is part of, a pair of additional spring-loaded missile launchers flip down from the its sides. Slotting the key into the electronic cannon opens up the panels covering the front of the barrel, unlocking a different sound with its button is pressed. The paint job of the key is the principal difference between the Hasbro and Takara versions of the figure; the Japanese release features a metallic gold paint border around the key, furthering its resemblance to the Matrix. Other differences include more thoroughly painted knees and leg-armor cannons, yellow-painted signal lights above the cab, and the use of metal hinges to hold on Prime's wing tips, which were removable on Hasbro's version, and came disconnected in-package.
A Mega Super Collection Figure of Prime in his "normal mode" was released a few months after the first figure. He came with a translucent blue Star Saber, and a much larger version of the Convoy Gun accessory, creating a sense of comparative scale, even though he's the same height as the Super Mode figure. Like the Super Mode figure, only his right fist has a peg-hole in it, so he can't hold both weapons at once.
If Optimus led his troops back to the Decepticons’ poison lab, the convoy happened upon the Decepticons hauling barrels of poison out of the poison lab. Windcharger and Ironhide suggested two different plans to Optimus: Windcharger wanted to use his magnetic powers to cause a confusion, while Ironhide wanted to simply go in for a full frontal assault.
Most notably in terms of new tooling, the panels on the undersides of Powermaster Optimus Prime's forearms feature slots under the fists, which allow the guns to tab in and be held much more stably than with Ultra Magnus. And due to the amount of empty space in the cab area in vehicle mode, Powermaster Prime can fully transform without the need to remove his head.
The figure's transformation scheme is based on the original G1 figure, the only differences being that the fists are not removed but become the headlights, and instead of flipping backwards inside the chest, Diablock Convoy's noggin flips forwards with the aid of opening chest windows. A "laser rifle" in the shape of his ion cannon can be built from black bricks, and stickers bearing the Autobot faction symbol can be placed on his shoulders, although this is not recommended as it is designed to permanently stick to multiple tiles which dislodge easily and may damage the sticker.

Optimus Prime appears in the prequel novel Transformers: Ghosts of Yesterday, where he and a group of Autobots travel in the Ark searching for the Allspark, battling Starscream's Decepticons along the way. While going through a worm hole, the Autobots find themselves encountering a group of humans in a spacecraft reverse-engineered from studying Megatron. With this discovery, Prime realizes the significance of Earth, as both Megatron and the Allspark are there. After saving Bumblebee from a pit of rock-chewing cave worms, Prime battles Starscream. He is about to be gunned down by Starscream and Bonecrusher when he is saved by the human craft. In retaliation, Starscream obliterates it.
The Transformers toyline was created from toy molds mostly produced by Japanese company Takara in the toylines Car-Robots (Diaclone) and Micro Change (Microman). Other toy molds from other companies such as Bandai were used as well. In 1984, Hasbro bought the distribution rights to the molds and rebranded them as the Transformers for distribution in North America. They approached Marvel Comics to create a backstory with names and short descriptions for each character, most of which were written by Bob Budiansky.
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.
When Sideswipe was accused and convicted of destroying the Nova Suspension Bridge, Optimus was infuriated that one of his own Autobots could commit such a heinous act. Optimus was tasked to hunt down and deactivate Sideswipe, though the task proved to be easy as Sideswipe did not run, hide or resist. After Optimus had deactivated Sideswipe, he was approached by Prowl, who pointed out that Sideswipe's actions made little sense, as he had committed the crime in broad daylight before many witnesses. Agreeing that the Decepticons might be behind the situation, Optimus allowed Prowl to take a team of Autobots to Carob Island to clear Sideswipe's name while Optimus and Jazz stayed behind to continue working on human/Autobot relations. Prowl returned with evidence that it was indeed a Decepticon-controlled clone of Sideswipe that had committed the crime. Optimus then presumably reactivated Sideswipe when his name was cleared.
