At some point, Rodimus learned that the world known simply as Planet Q was under threat from the world-devourer, Unicron, but arrived too late to prevent its destruction. Years later, however, he encountered the planet's surviving ruler, Alpha Q, and sided with him in his plan to use Energon to regenerate and restore all the worlds consumed by Unicron – a plan that put him in opposition with Optimus Prime when they encountered each other once again. When Megatron succeeded in reactivating Unicron, however, Rodimus relented and submitted himself and his troops to Optimus Prime's command, and they were integrated into the main Autobot force as the battles continued to defend Alpha Q's successfully-regenerated worlds against the Decepticons.
This Kabaya candy toy of Cybertron Optimus Prime transformed into cab mode through disassembling into its component pieces and being rebuilt, hence the line's name of Blockformers. He came with his hand-held rifle, and a stick of chewing gum. Each figure in the Blockformers line came with additional pieces that could combine with Prime to either make his trailer in vehicle mode, or convert his robot form into Super Mode. Prime himself came with his missile pod/shoulder brackets, his leg armor and guns, his right cannon came with Leobreaker, his backpack and wings came with Override, his Super Mode head came with Scourge, and his left cannon came with Evac.
The centerpiece of the power-up robot mode is Prime's gigantic Ultimax Super Cannon, an electronic light-and-sound weapon the size and mass of a Deluxe figure. The whole cannon attaches to a special socket slightly behind Prime's shoulders, can store on the back or flip over to be gripped in both fists in armor mode, or stored upside-down underneath the trailer in truck mode. When pointed forward, the cannon has a larger helmet styled after Prime's own with a large translucent face shield featuring a painted targeting system. The weapon has three electronic modes: each of two small buttons plays its own weapon-firing noise and flashes one set of lights, while the large pull-switch in the cannon's center plays the sounds of a powerful barrage, flashing both sets of lights and (every third time) finishing off with the declaration "I am Optimus Prime". The Ultimax Super Cannon also has two of its own 5mm ports for even more MechTech firepower. When mounted on his back, the Cannon has two hook-like sections that securely lock into the "backpack", allowing the Ultimax weapon to serve as a handle for Optimus' imaginary "flight" operations.
A non-transforming but highly articulated Optimus Prime action figure(ine), Revoltech Convoy uses the Revoltech "revolver joints" for maximum poseability. Convoy comes with a Matrix and ion blaster accessories, as well as a few alternate hands. His sculpting is explicitly in the style of Pat "serfdom" Lee's interpretation of Optimus Prime in the Dreamwave Generation One comics, but due to physical constraints has no lack of perspective.
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.
The Monster XL also features not one, but TWO barrels with 6 different nozzles per barrel. That adds up to about 36 different ways to put out your best friend's eye. The ludicrous weight and the fact that it takes 43 fucking pumps to get the water up to pressure offer up reasonable disadvantages, but since water gun fights are always half water gun fight and half "who brought the biggest dick" competition, none of that really matters.
The character of Optimus Prime first appears in the 2007 Transformers film as the leader of the Autobots in the search for the Allspark. He intends to destroy it, even if it means sacrificing himself, before the Decepticons can use it to create a new army to conquer the universe. After arriving and scanning a Peterbilt truck, Optimus greets Sam Witwicky and Mikaela Banes, introducing his men and explaining why they have come to Earth. During the final battle, Optimus slays the hate-filled Decepticon Bonecrusher and faces his ancient enemy, Megatron. Unable to match Megatron in combat, Optimus urges Sam to push the Allspark into his chest, which will destroy them both. Instead, Sam rams the Allspark into Megatron's chest, destroying it and killing the Decepticon leader. The film ends with Optimus sending out a deep-space signal, inviting other Autobots to join them on Earth.
Prime is loaded with a ridiculous number of features and accessories. The robot itself is highly poseable, and both the smokestacks on Prime's shoulders and the fuel tanks on his legs can be rotated forward to act as guns, even featuring sculpted detail to this effect. As ever, he comes with a trailer that opens up into his crazy-detailed Combat Deck, featuring more action features than ever before. In trailer mode alone, it features a flip-down support stand so it can stand alone, a spring-loaded pop-out ramp instead of a fold-down one, and when the trailer is split for transformation, the traditional support legs underneath automatically swing out into place. The trailer houses most of Prime's accessories, including his ion blaster (with a moveable ammo clip to allow for multiple poses) and energon-axe, as well as his classic gas pump accessory, now with a poseable wire instead of a rubber hose. Two fold-out compartments provide storage space for six of Prime's interchangeable fists, while the other two remain attached the robot: two clenched, two open, a pointing right fist, a tilted left fist (for holding the ion blaster's ammo clip), and two fists with slots to grip the miniscule Matrix of Leadership that fits in a tiny chamber in Prime's chest. The Combat Deck's artillery robot features two flip-out handles that Prime can grip as if aiming the drone's guns, and Roller is also included, with three different 3mm ports to hold Prime's gun and gas pump. Lastly, Prime comes with a rocket pack like those used by the Autobots in such Generation 1 cartoon episodes as "Dinobot Island", and a stand shaped like the Autobot insignia that allows him to be displayed in mid-air, as if in flight. The rocket pack also has 3mm ports for Prime's weapons, and stores on the front of the trailer in vehicle mode.
Optimus Prime is the fictional protagonist of the Transformers: Robots in Disguise (Fire Convoy in the original Japanese version) branch of the Transformers universe. Based on the character of the same name, Prime once again leads the Autobots against the Decepticons. His voice actor, Neil Kaplan, does his voice in a style reminiscent of that of Peter Cullen, the voice of the original Optimus Prime. Wired Magazine nominated Fire Convoy as one 12 most ridiculous Transformers ideas of all time.
