One detail not reflected in most of Hasbro's photos is that the sun visors above Prime's windows are mounted on ball joints and can be positioned like they are in his CG design. The hood halves on his arms can slide up on their hinges and the blue panels at the back of Prime's lower legs can be pulled out slightly as well for further screen accuracy.
His trailer opens up into his Combat Deck, which features a missile-armed repair drone pod (with seating for one) mounted upon a boom lift arm. Situated in the base of this boom is a spring-loaded launcher that can be used to launch Roller out of the Combat Deck. Roller himself has seating for 4 passengers, and can be equipped to carry Optimus Prime's rifle or a fuel pump. The interior space of the trailer allows storage room for one Autobot car.
The problem there is that Star Wars took over the Space theme and Harry Potter took over the Castle theme. Just keeping up with the kids- sign of the times. What’s a castle lover to do? Compare 6075 (Castle) with (7094 Kings Castle Siege) and 4757 (Hogwarts) and they all have their own fantastic attributes. Sell the Harry minifigs and buy some crownies- problem solved.
After their own Optimus Prime disappeared, Scavenger and Smokescreen discovered an alternate version of Optimus Prime lying unconscious and barely alive in Autobase Earth. Though Red Alert did what he could, the mysterious Prime reactivated only long enough to utter a cryptic statement about the walls crumbling and the coming of chaos, then died.

Simon Furman's "Alignment", a text story available through Transforce, a British Transformers convention, mentions Prime falling during what was intended to be the final conflict with the Decepticons at Pinea Omicron, long after the events of the Generation 2 comic book. He managed to defeat Galvatron II, but in doing so, was damaged such that Grimlock had to engage a stasis field around him to save his flickering Spark, making Prime a living war monument.
Bumblebee, being the popular character he is, was one of the first five characters inducted into the Hall in 2010, during a ceremony at BotCon; the convention for all things Transformers. He was joined, not surprisingly, by other super-popular transformers: Optimus Prime, Megatron, Starscream, and the Dinobots. Humans enshrined in the Transformers Hall of Fame over the last few years include everyone from director Michael Bay to Peter Cullen (the iconic voice of Optimus).
Megatron is captured by the Autobot Targetmasters in the episode "Do Over". When Optimus learns Megatron has been captured, he rushes to be the one who kills his old enemy, despite the closing launch window of the Ark. When confronted by Optimus Prime, Megatron attempts to use the Autobot Targetmaster Nightstick to shoot the Autobot leader, but Nightstick takes control of Megatron's arm. Megatron then tricks Optimus into using Megatron's own sword to cut his hand off, freeing him from Nightstick. Optimus fails to kill his foe and misses the launching of the Ark, which has been taken over by Rodimus. He then takes out his anger on Blurr.
The figure has diecast in its feet, shins, and abdomen. It features pinstriped flames, articulated fingers, a headsculpt with a face that can rotate between masked and unmasked modes in a method identical to Armor Knight Optimus Prime's, and an abdomen that opens to reveal a chamber housing a diecast Matrix of Leadership. He comes with said Matrix, his Ion Cannon, and a pair of Energy Swords that tab in behind his wrists (the hands unfortunately have to be bent forward to accommodate these). All three weapons can combine and store on the fifth wheel in vehicle mode.
The third version  would quite possibly have been the most gimmick loaded Transformer in the history of the line, simultaneously being a Powermaster, Headmaster, and Triple Changer. The Headmaster also would have been a Triple Changer, turning into a sort of armored four-wheeled rover (Roller II?) and robot as well as a rather silly looking Optimus Prime head with four vertically aligned wheels jutting off the sides. It seems that when the extra Headmaster gimmick was scrapped, the super mode head remained separate rather than being reintegrated into the trailer hitch such as on the earliest design. Notably, the body of this design is extremely close to the final design.
Released as part of the Allspark Power refresh of the movie line, First Strike Optimus Prime is an extensive redeco of Voyager class Optimus Prime in a colour scheme based upon Generation 1 and Classics Optimus Prime. The included toy bio describes this coloring as Prime paying tribute to the markings he wore as a young soldier when the war began. Due to the transformation scheme, this figure actually ends up being less like its G1 counterpart in robot mode, a sacrifice made for the slavish redeco of the vehicle mode. You can't have your cake and eat it too, folks.
This gold vacuum metallized (save for his black joints, which they were made out of unpaintable plastic) Protoform Optimus Prime figure was featured as a Lucky Draw giveaway (along side similarly gold vac-metal versions of Voyager class Optimus Prime and Protoform Starscream) in the December 2007 issue of TV Magazine. Released in 2008, only 5 pieces were made, making it one of the rarest Lucky Draw figures; the images at right represent the only known photographs of it.
The Hasbro stock photos of the toy is slightly mistransformed: his pectoral armor is not folded correctly in robot mode. At least a very small number of units feature a faceplate-less head sculpt which was probably intended for a later retool, but so far there is no news about this pretool being released in the future. This figure was also released in Toys R Us Japan in May 1st, 2017 as a store exclusive, likewise identical to the Hasbro release.
In 1989, the entire line became limited to Pretenders and Micromasters. For the first time, the Transformers received a new design for their title logo. But many also regarded this as a time of a dearth in creativity and the lowest point in the toyline's history. The year 1990 saw the last American burst with the release of more Micromaster characters and the introduction of the Action Masters, non-transforming action figures who came with Transforming companions. Larger Action Master sets came with transforming vehicles and bases. The Action Master line was criticized for its perceived desperation for a gimmick, although it had a few defenders. The line predictably faded and would be the last Transformers output in the US until 1992.
An additional oddity is that unlike every other toy in the Go! toyline, Optimus Exprime came packaged in a box without a window. This is potentially because of the sheer amount of information TakaraTomy wanted to print on the box, or because they were unable to fit him into the box in robot mode with all of his accessories displayed. Whatever the reason, it left him with a smaller box than the other voyagers in the line, a substantially-altered box layout, and a much shorter profile.
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.
