Optimus Prime is the awe-inspiring leader of the Autobot forces. Selfless and endlessly courageous, he is the complete opposite of his mortal enemy Megatron. Originally a mere civilian known as Orion Pax or Optronix, he was chosen by the Matrix of Leadership to command, the first in a number of heavy burdens he has been forced to bear. Another is his bringing of the Transformers' conflict to Earth. Every casualty, human or Cybertronian weighs heavily on his spark. He does not show this side to his soldiers and never succumbs to despair. The Autobots need a decisive, charismatic leader and that is what he gives them. It was that leadership which turned the tide of the Great War.
This version of Optimus Prime is an all new mold, being the most movie accurate so far — or at least he was until Buster Prime came out. It comes with his two energon blades, and does not have a large gap at the back of the cab like the previous Leader-class Optimus Prime. It can combine with Leader class Jetfire to form Jetpower Optimus Prime. He is also very hard to transform. The process involves unclipping his firewall from his chest in a fashion that harkens to dissecting toys that lack screws, rivets or glue. In the meantime, he keeps saying, "I am Optimus Prime," over and over due to an overly sensitive voice clip trigger. Even the most die-hard Peter Cullen fan will be sick of his voice after five minutes of playing with this toy. That aside, the quality and articulation is top-notch and the poseability is amazing. Spring-loaded panels feature in his legs as well as ratcheting ball-and-socket ankles, G1 "transforming" sound effects, and multiple "Mech Alive" features raise the bar on this figure. Of note, the fists cannot accomodate standard accessories, and on test-shots of "Power Up" mode Prime has articulated fingers, like the 2007 toy, but this feature was dropped. Also, trying to transform Optimus from robot to vehicle mode can be very difficult at first.
Part of a cross-promotion between Toyota and TakaraTomy, the deluxe-sized FJ Optimus Prime transforms into an FJ Cruiser, with his axe weapon becoming the vehicle's spare tire. The vehicle mode's body panels come packaged on the sprue, and can then be clipped onto the core figure. The mass retail release of FJ Optimus includes yellow and white panels, whilst further color variations were available when purchasing an FJ Cruiser at Japanese Toyota dealerships. As is typical of TakaraTomy exclusives, these variants came in grayscale packaging.
Although the character was redesigned to some extent, like the other characters in the film, many classic design elements remain in his robot mode including a predominantly red torso, primarily blue legs, the presence of windows in his chest, smoke stacks on his shoulders, and a head design influenced by the original, featuring the iconic faceplate and ear finials. The faceplate is able to retract to reveal a mouth. His weapons include his iconic ion blaster, a Barrage cannon, two retractable energon blades that extend from his forearms, which is a homage to Prime's energy axe in the Generation 1 animated series, and two retractable energon hooks that extend from his wrists. The trailer contains an energy axe, a shield, and flight gear. In the later IDW comics, he displays the ability to produce a holographic driver.
Part of the first wave of TakaraTomy Lost Age: Movie Advanced toys, this Japanese-exclusive redeco of 2007 Transformers Protoform Optimus Prime is given a Generation 1-styled color scheme (which is also based on his appearances in IDW's Transformers: Foundation comic-book mini-series). Protoform Optimus Prime transforms into his "entry" mode. This mode somewhat resembles a cybertronic truck, with false wheels sculpted onto the sides, and Optimus Prime's trademark windows in front. His now-blue flame decoration piece fits to the back of the "vehicle", creating the illusion of a flaming comet's tail (Not sure if this was mean to represent his jetpack blast effect or his atmospheric entry heat effect, which is for no reason: entirely blue instead of hot red). The bottom of the vehicle has small wheels to roll the toy across smooth surfaces.
