This Optimus Prime is an extensive screen-accurate redeco of the Dark of the Moon Supreme Class/Leader Class Striker retool, using the Ion Blaster accessory from the Buster Optimus Prime and the Toys R Us Japan-exclusive battle blade accessories. He also comes with the Knuckle piece and the Battle Hooks and uses the 2-2-1 articulated fingers featured from the second Asia Premium Series release. He also features a Japanese language sound box for his voice gimmick, replacing Peter Cullen's "I am Optimus Prime" voice line.
This miniature model kit of Energon Optimus Prime comes unassembled and unpainted, moulded mainly from white, red and black plastic and featuring some stickers for essential detail. Standing at around 4.5 inches tall, he comes with his Prime Force drones and can combine with them in the usual ways; while Fire-1, Gyro-2 and Digger-3 are moulded in their normal colours, Submarine-4 is stuck being black, and like every other non-color-molded, non-stickered detail on the kit, must be painted by the buyer. Prime's transformation involves removing his feet and head (an alternate Super Mode head is included, as his antenna does not transform into a helmet), and he does not come with a trailer for the Prime Force, but his gun can shoot small orange plastic BBs via a pressure-launching mechanism, and he comes with a small gold-chromed Energon star that fits onto his left shoulder. The kit also comes with "Episode 1" of the "Optimus Prime VS Scourge" mini-comic, printed on the back of the instructions.
It may be that the price of an individual brick has gone down over time, but what does it matter if the size of the bricks has decreased overtime? Sure, the average number of pieces in a set has increased, but how many of those pieces are tiny details? To answer this question, I compiled all the weight data on brickset.com and compared the sets by their price per gram in a similar fashion to how I compared them by price of piece. Below is the chart of my results (prices are in US dollars).
Optimus Prime transforms into a red and blue semi truck of likely fictitious origin. In keeping with the simplified transformation scheme of the Rescue Bots line, Optimus Prime transforms from truck to robot when his legs are folded down, at which point his head, arms, and hands emerge; folding his toes into position will finish the transformation.
Early versions of this storyline featured Rodimus returning as "Rodimus Primal," a techno-organic Maximal with a form similar to Optimal Optimus'. This concept was discarded in favor of Rodimus working alongside Primal Prime, but was later adapted for a storyline feature in "Ask Vector Prime." In an alternate reality where Starscream had possessed Waspinator and brought a premature end to the Beast Wars, Rodimus Primal led the Wreckers as one of several resistance group's to Megatron's rule over Cybertron. Eventually, Megatron was overthrown by his rebellious generals Obsidian and Tankor, splintering the Vehicon force prior to the pair being abducted by Unicron. Without Obsidian's leadership, the Vehicons crumbled, and Rodimus Primal became part of a new Cybertronian ruling council that also included "Waspscream," Magmatron, and Mutant leader Icebird.
In robot mode, like Combat Hero Prime, the bottom of the truck became his familiar windowed chest based upon the original Optimus Prime toy. His main gimmick was light up LED headlights, and a lightpipe in the bottom of his right fist, illuminated by an LED in his right forearm, that would illuminate his clear sword or his double-barreled rifle if they were used in that hand. All three LEDs were activated simultaneously by pressing the sunroof-like depression on the roof of the truck.
