Optimus took the mantle of leadership as the civil war against the Decepticons erupted, and would remain in that position for the next nine million years. Ariel was rebuilt into Elita One, the commander of the Autobot resistance on Cybertron. The fate of Dion is left unrevealed. It has been speculated by fans that Dion might have become Ironhide or Ultra Magnus just as Orion and Ariel became Optimus and Elita, but this remains fan speculation only, and, his close friendship with Optimus notwithstanding, there is no evidence to support the idea.
Prime got his own rap segment. He was seen in his "Combat" toy body, waiting for Megatron as he attacked a human subdivision. Prime converted to robot form, blew up Megatron's weapon at point blank range, and slugged it out with him. Apparently emerging victorious, he was next shown sitting next to an identical truck, which kid mistook for the real thing. The real Prime then transformed and picked up the kid, inspecting the human with his cold, lifeless, flashing red optics. Combat Heroes commercial
In robot mode, Voyager class Optimus Prime is proportionally more accurate to his CGI design than the leader class toy and has a more accurate headsculpt, but due to the aforementioned lessened complexity significant sacrifices had to be made, such as "cheats" to the transformation sequence, to achieve this and thus he is overall less accurate than he initially appears. In addition to previously mentioned changes, he carries much of the truck's front hood, grill and fenders on his back like a backpack. However, he maintains a superb level of articulation and posability.
Menasor cut off Prime's escape and handed him the Reflector trio, who confronted Prime with a hologram of Serpent O.R. The new Decepticon leader carried Megatron's memories and information downloaded from Soundwave, from which he learned of the Matrix of Leadership. Serpent O.R. offered Optimus a trade: hostages and peace if he handed over the Matrix. Optimus agreed.
This small version of Energon Optimus Prime was released by Kabaya as part of their DX Transformers line of candy toys. Prime transforms in the same manner as the larger Energon figures do, though his arms have to be removed at the shoulder and reinserted into his back to form truck mode. The Prime Force were sold in a separate set in the DX Transformers series, and can combine with Prime to form his Super Mode. Optimus came with a stick of gum.
Eject lamented that all the great and famous Cybertronians, including Optimus Prime, were long gone by the time Cybertron was controlled by the Builder Assembly. Broken Windshields The Maximal Overshoot experienced a series of visions from Cybertron's past after discovering the Oracle, including Optimus Prime launching the Ark during the Great War. Cultural Appropriation
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
The TakaraTomy "Autobot Alliance" release of this toy has some significant differences, including casting the red plastic in a darker shade, making his shin and wheel joints grey rather than Hasbro's bronze, painting the Matrix of Leadership silver, and swapping out the dual energon swords for battle hooks, similar to 2010's Leader class Optimus Prime. However, due to the Japanese release retaining the Hasbro packaging, the box still advertises the dual energon swords rather than the hooks. He retains the masked face used for the Hasbro release.
