This new smaller mold of Optimus Prime features a similar transformation to the original toy. Unlike most transformable figures in this line, Optimus completely lacks 5mm fist holes. Compared to the finalized toy, the product photo on the back of the box has a number of deco differences, most notably silver thighs and white accents above the front windows in addition to those below. The same box photo and the more deco-accurate stock photo (right) also neglect to fold out his fists, which is the only other step in his two-step transformation.
Entertainment Pack Optimus Prime is a slight redeco of the SDCC figure, with some deco differences between the SDCC release; this version has gray windows instead of blue and is missing some of the silver deco on the helmet and roof/feet, as well as the yellow paint on his lights. His midriff is also darker. Optimus also comes with a similarly-scaled Megatron and PVC figurines of Jack Darby, Miko Nakadai, and Raf Esquivel.
This Collector's Edition Japanese e-HOBBY exclusive was a redeco of Targetmaster Kup, released in conjunction with the 2006 reissue of Kup and designed to represent the character Orion Pax from the Generation 1 television series episode "War Dawn". Orion transforms into a Cybertronic pickup truck and came with both a gun and Barrelroller, a redeco of Recoil. He has full shoulder rotation, though the way his elbows are set up means he cannot make full use of their joints. His legs feature no articulation whatsoever.
Over the course of the next twenty years, the Decepticons succeeded in seizing control of all of Cybertron, forcing the Autobots to operate from their new city on Earth and two bases on Cybertron's moons. In the Earth year 2005, Prime, stationed on Moonbase One, dispatched troops to Earth to acquire energy for an upcoming strike on Cybertron. The Decepticons, however, got wind of the plan and used the shuttle run to attack Autobot City. A distress call summoned Prime and support troops to Earth. In the fearsome, ensuing, epic battle with Megatron, Optimus Prime sustained fatal wounds, but not before turning the tide of battle and forcing the Decepticons to flee. Despite the efforts of Perceptor, Optimus Prime went offline after passing the Matrix and role of leader to Ultra Magnus. His last words were "Until that day... 'till all are one." The Matrix later fell into the hands of Galvatron, a recreated Megatron, and was finally taken back by the young Autobot Hot Rod, who became Rodimus Prime after bearing the Matrix. In season 3, set a year after the events in The Transformers: The Movie, Rodimus was the new leader of the Autobots.
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.
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.
