Optimus Prime and his troops lay deactivated on the Fera Islands for three million years until G.I. Joe stumbled upon them one day in 1939. The Line The Autobots were reactivated by a repair drone and given new disguises, with Optimus Prime being reformatted into an unknown World War II-era human vehicle. He explained to Duke who they were, and learned that Megatron's Decepticons had been reactivated a year prior, and were currently wreaking havoc on Europe along with Cobra. While hesitant at first, Optimus Prime soon joined G.I. Joe in their mission to destroy Cobra and the Decepticons. Transformed After commanding the Aerialbots to get the Seekers out of the way, Prime advanced across the Fera Islands, but met resistance in the form of Rumble. Trial by Fire
Not depicted in the instructions or stock photos, Roller can attach to Prime in vehicle mode via two tabs on the vehicle front which slot into two corresponding slots on Prime's feet. Another undocumented feature is that the butt of the Ion Blaster can be inserted between the barrels of Roller's weapon mode to form a longer weapon. Also not shown in the instructions but depicted on the stock photo on the card-back is that Prime's shoulderpads can be rotated up; the intended positioning for this is notched, although you can position them at other angles.
Later, the Transformers were all transported to Cybertron by Primus to battle Unicron. Although Unicron had tainted the Matrix after killing Thunderwing, Prime managed to reacquire and purify the Matrix. Prime then sacrificed his life one more time to destroy Unicron by plunging the Matrix into his maw. The Powermaster process, however, had been working to fully bond Prime and Hi-Q. Prime's death completed the process, and the two minds and souls became one. Hi-Q's biomechanical body was stripped down and reconstructed by the Last Autobot, resurrecting Optimus Prime once more with the two minds now one. Prime rejoined the other Transformers on the planet Klo and routed Bludgeon's Decepticons.
In the "Transformers" film, the robots had more of an alien feel to them to fit the theme of an alien invasion. The robots (stated by Optimus Prime) in the film are actual sentient organisms and not just giant, mindless, and mechanical machines. The robots can also speak their own alien language sounding like what seems to be based on different pitches and frequencies. Alongside that, they gave them more alien features that probably wasn't mentioned in the comics or T.V. series such as a highly advanced exoskeleton, force field, and a special "alien meteoroid" mode which they transform into individually and arrive on earth in. The exoskeleton is a "self-regenerating metal" in which the aliens are composed of (stated in the film) that is the equivalent of living skin that heals itself.
When the warlord Shokaract, powered by Unicron's Dark Essence, traveled into the past to secure his own future, the occupants of J'nwan decided to act. Optimus Prime, Megatron, Soundwave, and Grimlock joined Sandstorm on prehistoric Earth during the time of the Beast Wars where the battle with Shokaract had already begun. When the Covenant arrived to vanquish the Dark Essence and defeat Shokaract, Optimus Prime and the others escaped through portals as that timeline was erased from existence. Terminus Departure
A giant-sized transforming Optimus Prime figure is set to be released for the third film. The set comes with a Leader Class-sized Optimus Prime figure and a trailer that transforms into his Omega Combat Armor - both of which combine to form Prime's Ultimate mode. This set will be released on August 1st, 2011, a month after the film's premiere.
Upon discovering that the Matrix was the key to destroying Unicron, Optimus Prime and Ultra Magnus went alone to face Unicron while the rest of the Autobots executed the plan to restore the original timeline. They hoped that at least one of these plans would be successful. Prime was injured in the confrontation with Unicron and, although his injuries were not mortal, he passed the Matrix to Magnus, who shed his outer armor and managed to complete the mission, destroying Unicron.
Part of the third wave of Prime Cyberverse Commander Class toys, Nightwatch Optimus Prime is a redeco of Series 2 Cyberverse Optimus Prime, using the faceplate-less head sculpt that is gang-molded with the original head. His blue plastic is now gray, his smokestacks and thighs are left unpainted, he loses the Autobot insignia on his right forearm/door, and he gains yellow paint highlights for his eyes and lights, along with various other minor deco differences. Instead of the original release's cannons, he now comes with a pair of swords, which each have a pair of 3mm posts for wielding/mounting.
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.
