In a break from tradition, Energon Optimus Prime's large mode resembled a configuration similar to Voltron or to the Super Sentai action figures. This design was unpopular with many fans due to design issues with the toy. The small robot's body was large in proportion to his arms and legs which made the figure appear fat, earning it the nickname "Fatimus Prime" or "Obese-imus Prime". The 4 vehicles that combined with the robot were small, lacking the intricate detail that made other toys in the line popular. Fans were also angered by early releases of this toy in which the head was molded with a mouth rather than the traditional face plate design. Later releases of the toy eliminated the visible mouth feature.
1· To calculate the average price per piece in a year, I took the price per piece of each set made that year, multiplied it by the number of pieces in the set and then averaged all the weighted prices. I used a weighted average because when we are looking at the price per piece we are essentially saying we could buy x number of pieces for y dollars. Larger sets tend to have a lower price per piece so in effect you could get more pieces at that lower price that year. Note: this was done using US retail price data from Brickset.
Available only at Kay-Bee toys (well, at first), Machine Wars Optimus Prime is a redeco and slight modification of the European Generation One exclusive Turbomaster leader Thunder Clash, transforming into a Cybertronic truck cab. It also lacks the mouthplate, revealing the mouth. The trailer unit unfolds to become a missile-launching assault tower. The tower's gravity-feed missile launchers were retooled to accommodate the new, longer spring-loaded missiles in lieu of the much smaller original projectiles due to projectile choke-gate safety testing.
In Another Light, Rodimus finally assumes total control over the Autobots upon Optimus Prime and several of his closest loyalists being jettisoned into space and left near death following the Battle of Decepticon City. However, his reign came to a swift end when the group returned, having been reformatted into the Knights of Unicron. The heroically reborn Optimus, now known as Nova Prime, engaged his usurper in battle and defeated Rodimus, sending him plummeting into Cybertron's depths. However, Rodimus then encountered the malevolent Primus, who enlisted his aid and that of other "true Autobots" in ridding his surface of those he considered vermin-namely, all Decepticons and Autobots not loyal to the same cause. This would lead to an epic battle between Primus' minions and the heroic Transformers of their universe: Galvatron's Decepticons, Nova Prime's Autobots, and a group of Maximals created from Classics Autobots.
In an alternate version of this reality, Rodimus was forced to deal with a militant and aggressive Optimus Prime, and Cybertron was soon wracked by a three-way war between Optimus' Autobots, Rodimus' Omnicons, and Megatron's Decepticons. Unfortunately, the balance of the conflict tipped with the arrival of dimension-hopping tyrant Megazarak, whose Destructicons allied with the Decepticons, creating a force that soon annihilated Autobot and Omnicon alike. However, the Destructicons then turned upon their allies and destroyed them before being abducted by Unicron. This universe was then drained of all life and energy by Tornedron, whose creator Primacron was also destroyed.
For reasons unknown, his ion blaster was sculpted with a large, rectangular handle, requiring accommodating fists. In order to make use of the other weapons in the line (like his own rocket launcher and the solitarium weapons), he comes with an extra pair of replacement fists with smaller, circular peg-holes. This replacement-fist method is also used to plug in his clear-plastic energy axe.
Prime filled one of the chase figure slots for the tenth wave as well. This rare figure was the same as the regular Super Mode PVC, except instead of wielding his Convoy Gun, Prime was armed with the Star Saber sword. As with the previous chase figure, it could only be found in one out of every ten cases, and took the place of the full-colour Prime figure in that assortment.
Originally, Optimus Prime was created as the leader of the Autobots, though it is unknown how he was created or his origins. In a possible future, Megatron was threatened by the existence of the Aerialbots and had Shockwave build a time machine to send them back in time to get rid of them. However, he only ended up changing history for the better. In the revised timeline, Optimus Prime began his life as a robot named Orion Pax, a mostly defenseless dock worker during the Golden Age of Cybertron nine million years ago, with a girlfriend named Ariel and a best friend named Dion. During this time, a new breed of robot with new flight capabilities appeared on the planet that Orion idolized. When Megatron, the leader of the new group of robots, approached him with inquiries about using one of the dock warehouses, Orion was swayed by Megatron. Both Orion and Ariel were severely wounded when Megatron and his forces attacked in order to claim the energy stored there. Searching for someone to help them, the time-displaced Aerialbots took Orion and Ariel to the ancient Autobot, Alpha Trion, who used them as the first subjects for the new reconstruction process he had developed involving rebuilding the frail Autobot frames into more battle-hardy configurations.
