In 2004 the LEGO group was in trouble. They were losing money and losing market share to other toys and entertainment products4. In order to address some fundamental issues in their business, they needed to cut costs. Leading up to this crisis, LEGO bricks had been adding new designs and colors without consideration for the cost to the business. LEGO went through a large reorganization and cut the production of unique elements in half, the variety of colors in half, and the number of suppliers by 80%. This, in addition to an increase in licensed sets and an expansion into video games, saved the LEGO Company.
In robot mode, Voyager class Optimus Prime is proportionally more accurate to his CGI design than the leader class toy and has a more accurate headsculpt, but due to the aforementioned lessened complexity significant sacrifices had to be made, such as "cheats" to the transformation sequence, to achieve this and thus he is overall less accurate than he initially appears. In addition to previously mentioned changes, he carries much of the truck's front hood, grill and fenders on his back like a backpack. However, he maintains a superb level of articulation and posability.
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.
Part of the fifth wave of Kabaya's revival of the Transformers Gum series, this snap-on transforming model kit of War for Cybertron Optimus Prime is sculpted from red, light blue, and gray plastics, and uses stickers for detail. He comes with a blue non-transforming version of his hand-held blaster rifle, which mounts at the rear in vehicle mode. He comes packed with a model kit of Tigerbreast, and a stick of gum.
Transformers GT "GT-R Prime" is a heavy retool of Alternity Convoy, transforming into a 1:32 replica of the Motul Autech GT-R race car used by the Nismo team in the Super GT racing championship series. He retains the flip-out blasters of the Alternity toy and can also wield his new Impact Wrench Gun accessory (also called the "Optimus Rifle" on the Transformers GT website), a weapon based on the impact wrenches used in car repairs. Like all GT toys, Prime also comes with a GT Sister, poseable human figures themed after race queens, his partner being a lady named Misaki.
There is another factor that comes with the sticker shock. As I showed before, LEGO has had $100+ sets for a while. However, only recently have they produced sets even more pricy than that. When we were kids, the $100 set was the pinnacle of LEGO. It was the set we all aspired to own. It was the set we all went straight to at the store. Of course we rarely ended up with that set, but that was our dream.
For its release in Korea, Hasbro Asia provided a collector coin featuring truck-mode Optimus Prime on one side and "MP-01L" on the other. The coin came mounted on a card featuring lineart of the Autobot leader's head, the stark black design of which could be mistaken for promoting the earlier "Sleep Mode" release. The limited release (and general lack of enthusiasm for the collector coins in Korea) makes this one of the more difficult Masterpiece coins to find.
One of the Mini-Con limb-bots (Soundwave helmet) is based on the original movie version of Optimus. The main torso-bot is based on Generation 1 Optimus's original body. Two of his limbs are based on Armada Optimus Prime; one "normal" (Inferno helmet), one pre-Earth-body (Knock Out helmet). And the remaining one (Ironhide helmet)... actually looks to be based on the Optimus-like-but-not-Optimus Micromaster Overload! The heck?
Optimus Prime appears as leader of the Autobot forces in the Transformers: Timelines story "Shattered Glass" by Fun Publications. When Cliffjumper, the Generation 1 character from a parallel universe, is seemingly discovered alive, Optimus welcomes his old friend back to the Autobot fold. After learning that Clffjumper is not the evil Autobot he remembers, he shoots Cliffjumper and leaves him to fend for himself in the Rad Zone. Optimus plans to launch his new warship, the Ark, to conquer Earth, but Cliffjumper aids Megatron's heroic Decepticon forces in a successful attack on the Ark's launch platform.
Legends Class Optimus Prime is based on his original Generation 1 appearance. He features a fake grill for his robot mode, and his large legs result in a fairly thick and compact truck bed. He is part of "Reveal the Shield", a subline that outfits all its toys with rubsigns, and in this case, it's located on the left side of the truck/his left elbow.
Optimus was checking up on the Autobots' ongoing energy collecting campaign when Wheeljack informed him that a disturbance in Sector 33HM of space-time would eventually cause major problems in its time-stream. Optimus assigned the investigation of this disturbance to Bumblebee, then noted that Hot Rodimus had not completed his latest report, communications with the young Autobo having been lost while he was on his own mission. With a brief inspirational speech, he urged his subordinates to redouble their efforts in maintaining harmony throughout reality. Little did Optimus suspect that in his own universe, Megatron was planning a coup against the Autobots... Uprising
The new One-Step Optimus Prime toy transforms from a trailer truck into a robot in just one easy step! The toy features a similar transformation to the other One-Step Optimus Prime and One-Step Changer Movie Hound. The figure is only available as a "Special Edition Figure" in a 6-pack with the One-Step figures of Bumblebee, Steeljaw, Grimlock, Sideswipe, and Underbite, all of which are unchanged from their individual releases. This set was exclusive to Target stores in the United States and to Toys"R"Us stores in Canada.
After the rise of the Decepticons and the death of the merciless Zeta Prime, he became the Prime, and entered what would become a millions-of-years-long war of attrition with the Decepticons, which would lead to the death of Cybertron and the spreading of the Cybertronian civil war far beyond their homeworld in a push for resources. With the end of the war and the emptying of the Matrix of Leadership to restart Vector Sigma and rebirth Cybertron, he found himself rejected by the returning civilian population, and - secretly gladly - abdicated his rank and returned to his original name of Orion Pax as he travelled through the galaxy.
Optimus made his way to the Primal Basilica, where he found Perceptor standing over the Mistress of Flame's battered corpse. Unable to do anything for her, Prime activated the Basilica's defenses as a means of stalling Trypticon. Learning from Perceptor that Rodimus had given up the Matrix, the two entered the chamber of the Chorus of the Primes to have the Matrix returned to him. Desperate Actions However, Optimus revealed the Matrix was not for him, but rather for Perceptor, as he wanted to make sure it would be taken as far away from Trypticon's grasp as possible. He guided Perceptor to a secret exit from the Basilica and sent the scientist on his way. Run for Our Lives Warned by the Chorus to "beware the power of the Primes", Optimus charged back towards the battlefield and began attacking Trypticon, rescuing Victorion. Optimus led the Combiners in battle against Trypticon, but the Titan managed to hit him, sending him hurtling towards some sharp rubble. Thankfully, he was caught at the last moment by Fortress Maximus. In Good Hands
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.
Power Surge Optimus Prime is a new mold, in the size of a Leader Class figure, which transforms in 7 steps. It comes with the Mini-Con Aerobolt, who transforms from a bird to his chestplate. This triggers electronic lights and sounds, as well as deploying a mask, two shoulder cannons, and a pair of large wings for the larger robot. His front truck kibble can be removed, but you can transform him into vehicle mode with the kibble on.
An extensive redeco of the Protoform Optimus Prime mold that was exclusively available at the Japanese C3xHobby Convention in August of 2007, and later offered by e-HOBBY in limited quantities. Most of the body is made out of transparent turquoise plastic in order to mimic its frozen state in the "coldness" of space, while orange paint is used on the front end of the "entry" mode, mimicking the heat effects of sudden atmospheric entry. The flame attachment is made out of clear blue plastic, with the tail end being covered in gold paint.
During the war, Optimus was killed in battle by Megatron, but was eventually resurrected. The Fight Begins Coming to the dire realization that the war against the Decepticons had become a never-ending arms race, Optimus Prime challenged Megatron to single-combat, with their troops acting as witnesses to their terrible and final clash. The battle between both faction leaders ended with Megatron beaten down and goading Optimus into delivering the kill shot...
EZ Collection Gum Convoy is another redeco of Generations Legends Class Motorbreath, featuring the retooled parts, but this time omitting the sword. He is decoed once again in his Generation 2 colors (see above), with the black legs, but uses metallic red plastic, and is coated in metallic red, blue, and black paint. As per the toyline's name, he comes with a yellow candy-shelled piece of lemony-flavored gum.
