A redeco of Deluxe Earth Mode Optimus Prime with the jet pack attachments and a smaller version of Ultra Magnus' Mass Hammer, as seen in the "Endgame" series finale. The Wingblade attachments are also compatible with Voyager Optimus Prime. The figure never saw a release in the U.S. market due to Hasbro's decision to cancel the toy line, but a variation of it was made available in Japan.
The main Prime line in Japan, while mostly using the same molds, was quite a bit different from the Hasbro version. Hoping to snag a slightly-older market, the toys were given a bit of "model kit" vibe. Paint operations were reduced and replaced with old-fashioned sticker sheets, so you had to customize/complete the toy itself... and then there was the blatantly model-kit Arms Microns packed in with every toy.
There is also the release of Optimus Prime as a deluxe sized brown gorilla which is a repaint of the Beast Wars 10th anniversary Optimus Primal toy most likely trying to tie Optimus Prime in some way to the jungle planet Animatros in the Cybertron series. According to his bio, Optimus Prime was temporarily mutated into this form by the Animatros Cyber Planet Key. The colors of this toy are a homage to Transformers: Universe Optimus Primal.
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
As he and Prowl discussed the wisdom of evacuating, a huge explosion obliterated the Forum of Enlightenment. Optimus led a team there, realising that the destruction was a message from Megatron. Leaving his team, he ventured underground, encountering Shrapnel, who blasted him into a pit. The War Within #2 Exploring the underground, Prime had a strange vision of a transparent version of himself, which warned that he had to grasp Cybertron's significance. Then he was attacked by Soundwave and the Insecticons, whom he was able to easily best by using the labyrinthine environment to his advantage. He then felt himself led to a confrontation against Megatron, and both faction leaders met atop of a bridge, overlooking a deep abyss. Starscream blasted the bridge Optimus and Megatron were standing on, plunging them into the chasm. The War Within #3 Recovering, Prime heard another disembodied voice telling him about Cybertron. Before he could look for a way out, Megatron found him, and informed him about the true nature of the Matrix, telling Optimus how it could be used to power Cybertron's planetary engines, transforming it into a space-faring war-world. This spurred Optimus to fight back, but before long, Megatron took control of the battle, smashing his fist into Prime's chest to get at the Matrix. A blaze of light enveloped the pair, who found themselves abruptly on 20th century Earth. The War Within #4
Generations "Combat Hero Optimus Prime" is a metallic-blue, gunmetal, and red redeco of United Laser Optimus Prime, having the retooled tab, and being based on the canceled Generation 2 Combat Hero Optimus Prime figure, sporting a red mouthplate inspired by the official catalog image for the unreleased toy (packaged samples had featured a traditionally colored gray mouthplate). He comes packed with a (vaguely) Generation 2-styled Deluxe Class Autobot Jazz, as well as unchanged releases of Generations Legends Class Thundercracker and Motorbreath.
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.
