In "The Elite Guard", the Autobot Elite Guard, composed of Ultra Magnus, Jazz, and Sentinel Prime, arrive on Earth to reclaim the Allspark. They don't believe Optimus' story about the Decepticons and Sentinel Prime wishes to have him court-martialled. When a fragment of the Allspark causes a production line to go haywire, Optimus finally stands up to Sentinel, retrieving the fragment, and earning praise from Ultra Magnus.
After the Great War, Optimus Prime disappeared with other legends into the mysterious location on Cybertron dubbed J'nwan, where Optimus himself became the "Authority" who spoke on behalf of the others. Sandstorm, the leader of a rebellion in a 32nd-century firmly under the heel of the tyrannical Shokaract, entered J'nwan to plead with the heroes of Cybertron's past for aid. He hoped to convince them to join the fight against the Predacon warlord. After a mind-crushing journey which left all of his companions dead or deranged, Sandstorm finally found an audience with the Authority and his brethren, but they declined to help, with the Authority stating that their time was past and the war was no longer their war. The Authority then in some way manipulated Sandstorm's trip out of J'nwan such that it was comparatively short and simple. Paradox
Featuring a complex transformation, the front and back ends of the truck essentially fold and converge to become Optimus Prime's legs, as much of the truck rear is connected to the robot thighs via a series of folding panels. The rear wheel cowlings feature a hinge joint in the middle of them so they do not impede his knee articulation. The halves of the rear cabin of the cab, directly connected to the smokestacks, rotate and connect to his torso and unfold into his arms. As with most mainline Movie toys, Optimus Prime features Automorph gimmicks, and due to his price point, he has three of them. Firstly, during initial transformation, rotating his front fenders to become his heels flips the top parts of the grill to become his toes. Secondly, sliding out the double-barrel cannon in his right forearm flips out his spring-loaded Ion Blaster, which lands into place for his right hand. (The Ion Blaster can actually be popped off his forearm fairly easily, as it is held in place by a simple clip.) Optimus's final Automorph, located in his torso, is activated by flipping the silver lever on his stomach, activating a series of spring-loaded actions where the truck windows are pushed apart and the lever between them is raised, enabling the head to spring up from the chest cavity. At this point, yellow LEDs light up the chest windows and Optimus Prime's eyes, accompanied by a "powering up" sound effect.
This figure was made available again, without any changes, in 2015, this time in new packaging resembling the then-concurrent packaging design for the Generations line, but replacing the name "Generations" with "Authentic Transformers". It was also given a new Hasbro product code number and UPC barcode, thereby technically making it a separate product. In 2017, it was re-released again, this time in a minor variant of the 2014 version's packaging (including the original product code number and barcode) that now lacked the reference to the non-existing "Reveal the Shield" gimmick.
During the Cybertronian Civil War, Sentinel Prime was killed. Prior to his destruction, he bestowed the Matrix of Leadership to Optimus Prime, who became the new leader of the Autobots. Despite being one of the youngest Cybertronian leaders, Optimus demonstrated extraordinary courage and wisdom in the war against the Decepticons. He: treated all lives with benevolence, fought for freedom and peace, and continues to fight to protect the weak and maintain their beliefs.
The original Optimus Prime toy was a re-deco of the Diaclone Battle Convoy toy and 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 driver figures part of the Diaclone line. His trailer opens up into his Combat Deck, which features a missile-armed repair drone pod (with seating for one) mounted upon a boom lift arm. Situated in the base of this boom is a spring-loaded launcher that can be used to launch Roller out of the Combat Deck. Roller himself has seating for 4 passengers, and can be equipped to carry Optimus Prime's rifle or a fuel pump. The interior space of the trailer allows storage room for one Autobot car. In robot mode, he is armed with a black laser rifle, that, due to design, cannot be held straight. His fists are separate pieces which must be stored elsewhere in vehicle mode; there are pegs to store them in the trailer.
The lowest priced toys in the Armada line were three-packs of Mini-Cons. Each larger price point consisted of an Autobot or Decepticon who came with a Mini-Con partner. Mini-Cons could be used to unlock a variety of features on each larger robot, such as firing weapons, electronic lights and sounds, or alternate modes. Some three-pack Mini-Cons combined into other forms or had additional features. According to the storyline, Mini-Cons also enhanced the power of other Transformers, giving incentive to collect as many of them as possible.
