Unite for the Universe Optimus Prime would have been a redeco of the 2007 Optimus Prime Voyager-Class mold in a similar style to the Leader-Class Buster Optimus Prime (see below), with a much more accurate and detailed paint scheme, including white stenciled flames. He would have come with a set of Jetfire armour parts to form the powered-up Optimus Prime seen at end of Revenge of the Fallen, and due to not having to form Jetfire's robot mode or his jet mode, the armour parts are far more accurate to the movie's design of them than the leader class Jetfire toy could manage. While not combined to Optimus Prime, the armour can be arranged to form a sort of weapon emplacement mode or a jet engine on the back of Optimus's vehicle mode.
As the figurehead of the entire Transformers franchise, Optimus Prime has been on more pieces of merchandise than can be stated here. Several statues and busts of Optimus Prime as well as Optimus Prime themed objects have been released by various companies since the return of transformers to prominence, such as the "Optimus Prime Oral Care Station". Other figures released include various PVCs as part of Takara's "Super Collection Figure" line, which were later imported as part of Hasbro's "Heroes of Cybertron" series. Larger "Mega Collection Figure" PVCs were articulated and came with energy axe and gun figures.
Released as part of the Allspark Power refresh of the movie line, First Strike Optimus Prime is an extensive redeco of Voyager class Optimus Prime in a colour scheme based upon Generation 1 and Classics Optimus Prime. The included toy bio describes this coloring as Prime paying tribute to the markings he wore as a young soldier when the war began. Due to the transformation scheme, this figure actually ends up being less like its G1 counterpart in robot mode, a sacrifice made for the slavish redeco of the vehicle mode. You can't have your cake and eat it too, folks.
Available in the Timelines "Generation 2" 2-pack alongside Sgt. Hound at BotCon 2015, General Optimus Prime is a redeco of Generations Voyager Class Roadbuster based on the cancelled Generation 2 General Optimus Prime toy. He transforms into an off-road vehicle and comes with numerous weapons, all of which peg via 5mm post onto his vehicle rear/legs, shoulders, upper & lower arms, and hands: a spring-loaded, missile-firing launcher, a pistol, a rifle, and two small cannons that respectively form the scope and stock of the rifle. All of his weapons can combine to form an unwieldy superweapon. It was unknown if this figure has the loose ratcheted shoulder joints from the Legends release of the mold.
Then he dreamed of awakening, only to find his troops smashed. Realizing his only hope for survival lay with Cybertron, Optimus then boarded the ship the Autobots were repairing, and travelled back to his home planet. Arriving on Cybertron, he found it completely under Decepticon domination. Optimus then met an old Autobot codger who pleaded that he return to Earth to gather a force that could overthrow the Decepticon’s regime. Optimus remorsefully told the old Autobot that there could be no reinforcements from the planet Earth. The two Autobots were then swarmed by Decepticon police officers, who Optimus fought until his dying breath…
In Transformers: Alliance, Optimus Prime and the Autobots aid the human soldiers after the battle in Mission City and destroy the Allspark-powered machines that were created. A trailer is obtained for Optimus Prime to carry the remains of Jazz. The Autobots leave Mission City as the Sector 7 personnel arrive to claim the remains of the Decepticons. About a month later, Epps and Lennox contact Optimus Prime about aiding them in escorting the remains of the Decepticons to the naval yard. They are spied on by Barricade, who transmitts the information to Starscream.
When Sideswipe was accused and convicted of destroying the Nova Suspension Bridge, Optimus was infuriated that one of his own Autobots could commit such a heinous act. Optimus was tasked to hunt down and deactivate Sideswipe, though the task proved to be easy as Sideswipe did not run, hide or resist. After Optimus had deactivated Sideswipe, he was approached by Prowl, who pointed out that Sideswipe's actions made little sense, as he had committed the crime in broad daylight before many witnesses. Agreeing that the Decepticons might be behind the situation, Optimus allowed Prowl to take a team of Autobots to Carob Island to clear Sideswipe's name while Optimus and Jazz stayed behind to continue working on human/Autobot relations. Prowl returned with evidence that it was indeed a Decepticon-controlled clone of Sideswipe that had committed the crime. Optimus then presumably reactivated Sideswipe when his name was cleared.
