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.
"Garbage Truck" is a redeco of the same Optimus Prime toy in blue and white, a common coloration for Japanese garbage trucks that bears ends up bearing a coincidental resemblance to the Bot Shots Polar Assault Team Optimus. His stickers now picture his truck mode being loaded with garbage, his truck mode driving around, and the word "cleaning" in both English and Japanese.
Like all Predacons Rising releases, the Optimus Prime/Predaking two-pack was exclusive to Target stores in the United States and Canada and to Tesco stores in the UK, and is also supposed to be exclusive to Carrefour elsewhere in Europe (presumably in France and/or Spain, though there have been no sightings as of yet). It has also been found at Rossmann drug stores in Germany and Ripley stores in Chile and popped up at BigW stores in Australia much later, in mid-2014. Also, like all Predacons Rising multi-pack redecos of Beast Hunters Cyberverse figures, the Cyberverse logo is nowhere to be found on the packaging.
Alternators Optimus Prime transforms into an accurate, fully-licensed 1:24th scale Dodge Ram SRT-10. The vehicle mode features rubber tires, functional steering, opening hood, tail gate and doors with a detailed cabin interior. His robot mode body sculpt details are based upon the 20th Anniversary Optimus Prime toy. However, his headsculpt is based upon Powermaster Optimus Prime. He is armed with a small pistol that is formed from his engine.
Generations "Combat Hero Optimus Prime" is a metallic-blue, gunmetal, and red redeco of United Laser Optimus Prime, having the retooled tab, and being based on the canceled Generation 2 Combat Hero Optimus Prime figure, sporting a red mouthplate inspired by the official catalog image for the unreleased toy (packaged samples had featured a traditionally colored gray mouthplate). He comes packed with a (vaguely) Generation 2-styled Deluxe Class Autobot Jazz, as well as unchanged releases of Generations Legends Class Thundercracker and Motorbreath.
This release is a redeco of the Cyberverse Commander Optimus Prime figure, with a lighter gradient paint job that lacks the flames, and with Optimus sporting a G1 insignia. Instead of his jetpack and guns, he comes with his trailer/Armored Weapons Platform, which can transform into a base and exo-suit. The trailer itself features movie-style insignias.
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.
