The 1992 and 1993 European and Canadian releases make up what is often called "Generation 1.5", much to the annoyance of many UK fans. These toys are similar in design to the Generation 2 Transformers, having lightpipe eyes, and pastel colors. The 1993 European figures used the G2 faction symbols which Hasbro UK designed because their licence on the G1 symbols had expired. The 1993 figures were repackaged for European G2 release in 1994, and three subgroup molds got used in the US G2 line.
After a period of effective leadership, which saw the activation of several new Transformers including the Aerialbots, who Prime infused with life using the Matrix, Prime engaged Megatron in a video game duel for possession of a super fuel. Prime was victorious, but Megatron implemented a cheat code that killed Prime later. Autobot surgeon Ratchet's subsequent efforts to restore him were unsuccessful, and his body was launched into space. The Autobots were unaware of the presence of the physical Matrix within the corpse. The funeral barge eventually crashed on a giant moon and, as it lay there for an untold time, the Matrix reached out to nearby living organisms, studying and recreating them.
Another release of the Leader Class Optimus Prime figure, now redecoed from the original Revenge of the Fallen Leader Class mold, but with the gimmick-less arms from the Supreme Class retool, and a pair of articulated fingers which was not previously used for the original release. He also retains his pair of Energon Swords and Hooks, and his Knuckle piece. He also retains the fuel tanks that can combine to form his ion blaster. In terms of deco, he features a darker plastic color and paint (which resulted in a two-tone shades of silver & gunmetal), which is meant to go with this line's Jetfire.
This Classics Optimus Prime is a smaller, Deluxe Class figure with a noticeable physical resemblance to Takara's Robotmasters Prime figure, and a transformation that is about as successful. The figure is armed with a tommy gun-shaped laser rifle that transforms into a turret-like configuration and mounts on the rear of his truck mode, and features a spinning "power punch" action that sees the whole upper half of his torso spin when a button on his back is pressed. Pressing the button "unlocks" the spinning mechanism; pull hard on the button, and you can lock the torso back into place.
Certainly the most iconic, and most common, leader of the Autobots is Optimus Prime. But the thing about Optimus Prime is that he dies... a lot. And every time he dies, someone has to take his place-- until he’s invariably resurrected in one way or another, that is. In many storylines, including the original animated Transformers: The Movie, it’s Hot Rod who takes over as Rodimus Prime.
The mid-range Voyager class Movie Optimus Prime toy transforms into an amalgamation of the Kenworth W900 and the Peterbilt 379, making this toy fairly inaccurate to the actual vehicle Optimus Prime turned into. Because of the smaller size and lessened complexity, the Voyager class Optimus Prime features a significantly different transformation sequence compared to the Leader class toy, and indeed, the actual CGI design. However, as the actual truck cabin no longer forms his chest, the cabin now features a small interior with opening doors and a non-removable cowboy-hat-bedecked driver figurine that flips out of the seat when the driver's side door is opened.
Hot Rod has a youthful attitude, and serves as an older brother figure to Daniel Witwicky, son of Autobot ally Spike Witwicky. He has a sort of mentor-student relationship with the veteran Autobot Kup. He was also good friends with Springer and Arcee. Later in life, he temporarily bears the Autobot Matrix of Leadership and becomes Rodimus Prime (Rodimus Convoy in Japan), and new leader of the Autobots.
Part of the fifth wave of 2012-onwards Generations Deluxe Class toys, Thrilling 30 Orion Pax is a new mold with a robot mode inspired by Guido Guidi's design for the character, originally seen in Spotlight: Blurr. Some liberties have been taken with the original concept to facilitate his truck mode, which is a new design not based on the Guidi art. He comes with his Ion Blaster and an Energon Axe with a transparent red-orange blade, both of which can peg onto 5mm ports on his hands and vehicle rear sides. Although not depicted on the instructions, the Ion Blaster can also peg into the hole in the larger blade of the Energon Axe.
His original trailer is not included with the set; instead, he comes with a new deluxe-scaled trailer, not available with any other figure, based on the one towed by Prime in Dark of the Moon. The trailer is compatible with both figures, and sports 5mm post-holes that will hold (among many other things) G1 Prime's laser rifle and the MechTech weapon Movie Prime is armed with.
Optimus Prime is primarily voiced by Peter Cullen in most of his incarnations, who voiced him in the original series. Following the production of the 2007 film, Cullen reprised his role for the sequels and supporting media and would even voice Optimus in later series such as Transformers: Prime. Optimus has been voiced by a number of other voice actors in other series such as Neil Kaplan, Garry Chalk, and David Kaye in the series Transformers: Robots in Disguise, Unicron Trilogy, and Transformers Animated, respectively.
Scarlett later used the Brainwave Scanner to contact Optimus's spirit and guide him back to the mortal realm. In the physical world, Ultra Magnus challenged Megatron to a duel on a Dyson sphere surrounding the sun. The Autobot god had not ferried Optimus to the afterlife - he had merely repaired Optimus's body by taking it into himself. During the climatic duel, he allowed Optimus to burst free from within his armor. The reborn Optimus punched Megatron into the sun, then turned his attention to reclaiming the stolen Matrix from the Decepticons. After Atlas defeated the maddened Primus, Optimus healed Snake-Eyes' injuries. Optimus then turned his attention to returning Primus/Cybertron to its regular orbit. As the planet left the solar system, he departed aboard the Ark 2 alongside a crew of Joes and Autobots, in the hopes of contacting the Makers. The War Never Ends
The Autobots tracked SARA's energy signature to a decrepit old building. While a team headed by Jazz stormed the building's main floor as a distraction, Optimus, Hot Rodimus and Brawl infiltrated its basement covertly. Coming upon the Decepticons' inner sanctum, they found Megatron having already wired SARA into his own body! Horrified by this development, Optimus demanded to know what Megatron was planning to do. The true extent of Megatron's megalomania was then revealed; the Decepticon leader planned to use SARA's energy to become ruler of all space-time, even if it meant destroying his home dimension in the process. Both Hot Rodimus and Brawn were knocked aside by Megatron in short order, leaving Optimus with no back-up and few options. Deciding he needed to take down Megatron, even at the cost of his own life, Optimus transformed to vehicle mode and rammed the Decepticon. He then lost consciousness...
A larger version of Prime, with Advanced Automorph technology and a more complex transformation procedure. Has two sets of electronic sounds and lights that activate when the head pops up or when you press a button on the roof (in truck mode), and a single projectile weapon that can swing over the toy's right hand. Unlike Megatron (whose head is fixed) and Brawl (whose head is connected with a ball joint), Prime's head is limited to side movement due to the circuitry on his LED eyes. This figure has a folding cannon and a firing missile. With this figure standing nine inches tall and Optimus being 28 feet (336 inches) tall, the toy is about 1/37 scale.
Hot Rod then fought in the battle of Autobot City and saved the city for if he had not attacked Megatron, he would have destroyed it. Due to his attempted intervention in the epic battle between the Autobot leader, Optimus Prime and the Decepticon leader, Megatron, Prime was lethally injured. Before he died, the Matrix got passed on to the Autobot Ultra Magnus, whom he referred to as "old friend", despite protestations.
