Aside from the Powermaster feature itself, the main gimmick of the toy is the ability of the truck cab to combine with the trailer to form the larger "Super Optimus Prime" figure. This is essentially accomplished by standing the trailer up, folding the cab in half and inserting it into the empty cavity in the trailer's torso, forming an imposing—if almost entirely unposeable—robot form armed with all four weapons. The head of this super robot form is a separate piece which can be stored in the rear of Prime's trailer when not in use. While Hi-Q was always shown plugged into Prime's chest in artwork of this mode (as seen in the picture here), this was actually entirely unnecessary as transforming into Super Optimus Prime didn't require the standard Prime toy's legs to be unlocked.
The project was crowd-funded through Japanese crowd-funding site Makuake. For 5,400 yen, contributors received an INFOBAR Optimus Prime, or for 16,200 yen, received INFOBAR Optimus Prime, INFOBAR Megatron and INFOBAR Bumblebee, the only way to obtain the last two items. The project received one million yen in the first 24 hours, ultimately topping out at over 32 million yen.
Optimus Prime appears near the end of the Decepticon Campaign. Sam and Mikaela inform Optimus that all the Autobots were defeated by the Decepticons. Optimus proclaims that they sacrificed their lives to protect the Allspark, and their sacrifice will not be in vain. Leaving Sam and Mikaela in a safe place, Optimus faces Megatron, but is defeated. Weakened and damaged, Optimus crawls to reach the Allspark. However, Megatron attacks Optimus with his chain-flail, killing him.
Optimus later led a convoy in search for a building site for Autobot City, which ran into a Decepticon ambush. Rodimus Prime remembers the Transformers greatest battle on Earth. He sent off several Autobots to get help, knowing this was the only chance of victory. Transformers Combat Data Those several Autobots were seen again, but Prime... wasn't.
Legends class Optimus Prime is an extremely simplified toy of the extremely complex movie design. As such, he features numerous unavoidable inaccuracies, such as not transforming or even looking very much like the original design or the larger toy versions in robot mode. However, proportionally Legends class Optimus Prime is not far off from the real truck and the Leader class toy's vehicle mode, aside from missing a smokestack on the driver's side. He is articulated at the shoulders and upper legs via ball-joints.
Upon witnessing the incredible power of a lightning storm for the first time, Optimus Prime had Sparkplug Witwicky explain the phenomenon to him. Intrigued by the potential of lightning, Prime put Huffer and Gears to work finding a way to harness its energy, so they could use it to aid in the rebuilding of their spaceship. Huffer constructed a giant lightning rod, and Optimus Prime and the Autobots gathered to watch its first test. They were shocked, however, when a fleet of battered, damaged Decepticons flew out of the mountain housing the antenna and off into the night. The evil robots had attempted to discover the device's secrets and been seriously electrocuted! Once the lightning rod had been checked, Prime vowed to make the lightning-harnessing technology the Autobots' gift to Earth once they had left the planet. Autobots' Lightning Strike
In the wake of this incident, the transformers managed to reclaim much of Cybertron. Mindful of the dangers of allowing humans like Cobra access Cybertronian technology, Prime sent Perceptor, Grimlock, Arcee, and Bumblebee on a mission to Earth. As it turned out, Prime's fears were well founded. The U.S. government had used parts from Megatron to create Serpent O.R., a cyborg designed to be a perfect weapon. A raid by Cobra allowed it to escape and gather an army of Decepticons on Cybertron, killing Bumblebee in the process. Despite the grief of losing Bumblebee, Prime continued on and rallied his comrades to do the same. Attacking the Autobot capital city, Serpentor's forces proved overwhelming, and Prime surrendered to ensure the Decepticons would cease fire and not kill another comrade. Realizing that Serpentor wanted the Autobot Matrix of Leadership, Prime broke free as Serpentor was distracted, but was unable to kill him. He was promptly attacked and nearly beaten to death by Razorclaw and Motormaster. He was subsequently forced to watch as Serpentor opened the Matrix. In doing so, Serpentor was not only reformatted into a transformer-like mechanoid, but was also shown the futility of the fighting by the Matrix. At this point, Cobra Commander was able to take control of Serpentor's body. In an attempt to stop him, Hawk opened the Matrix and was transformed into a great leader, rendering Cobra Commander comatose. As the Joes prepared to head home, Prime promised to record the Hawk-led humans' future.
This TakaraTomy Asian market-exclusive Leader Class two-pack consists of a redecoed Jetfire and a slightly altered Buster Optimus Prime. Buster Optimus Prime is almost identical to the single-pack Japanese release of the toy, but unlike the standalone Buster Prime, has a head with a faceplate, itself containing more paint details than the first release of Revenge of the Fallen Leader-class Optimus Prime. The flames are outlined with light blue instead of white for accuracy to the physical truck prop (though it ends up being inaccurate in robot mode). Jetfire has a subtle, more movie-accurate colour scheme.
The lowest priced toys in the Armada line were three-packs of Mini-Cons. Each larger price point consisted of an Autobot or Decepticon who came with a Mini-Con partner. Mini-Cons could be used to unlock a variety of features on each larger robot, such as firing weapons, electronic lights and sounds, or alternate modes. Some three-pack Mini-Cons combined into other forms or had additional features. According to the storyline, Mini-Cons also enhanced the power of other Transformers, giving incentive to collect as many of them as possible.
