A later prototype/mock-up was much closer to the final product but still has some noticeable differences, such as a head with much larger antennae, longer smokestacks and a front grille section that includes the rectangular section that would sport the "Freightliner" logo on the real-life truck (on the final toy, the rectangular section is part of the hinged upper section that includes the windows). It would have also been possible to attach the ion blaster to either of his shoulders.[12]
Optimus and his Autobots were aboard the Ark, on the run from the Decepticons. With him, Optimus had what Megatron was forever seeking; the AllSpark! With the ship taking heavy damage from the Autobots' pursuers, Optimus ordered Jazz to take them into an emergency quantum jump. Jazz informed Prime that the jump would take longer to initiate than the time the Decepticons would need to board their vessel. As such, Optimus entrusted the AllSpark to Bumblebee while he and the rest of the bridge crew steeled themselves to hold off their enemies. Thanks to Starscream breaking rank in the Decepticons' formation, Optimus was able to hold back Megatron, and with Heatwave's help, repel them from the ship just as it initiated the quantum jump. However, at that moment the AllSpark tumbled off-ship, falling into the quantum tunnel and seemingly being lost for good... Angry Birds Transformers #1

Available exclusively at Toys "R" Us, Rodimus transforms into a futuristic car that is a homage to the vehicle mode of Generation 1 Hot Rod. A panel on the car's hood, which is also the figure's chest, can be flipped to either show an engine block or the figure's Autobot insignia. The figure comes with an Energy Bow, capable of firing two missiles. His bow can also be tabbed to the roof of his car mode or snapped on his hand. The tabs that secure his bow in vehicle mode are 5mm wide, making it usable by other figures as well. His legs are normally bent for the underside of his car mode but can be locked straight during transformation.

Although peacetime in the decade that followed the apparent deaths of Unicron and Galvatron afforded Prime the opportunity to train his own elite squadron of Autobots the martial art of Kumite. The re-emergence of the war, however, forced him to return to his role as commander. The conflict for control of the Mini-Cons and the truths he was forced to face in his confrontation with Unicron seems to have changed him. Optimus Prime, Grand Convoy' in the Japanese version, was now a stern, more direct commander and shows little of the conflict that held him back before. Despite this, he is still known to make the same kind of decisions, which include an emphasis on team work and the foundation of the Autobot values.


The SS-03 version of Takara's Deluxe-class Optimus figure, based on the Anniversary release, was released in Hasbro markets in a two pack with the smaller Japanese Megatron figure. There are some tiny but notable differences between this and the Anniversary figure; the Hasbro version uses a more neutral dark-gray for the main body as opposed to the Takara version's blue-tinted dark-gray, plain dark-blue plastic rather than dark-blue-with-sparkles, and plain yellow paint for the cab's lights rather than sparkly-yellow/gold.
Part of the sixth wave of Custom Kreons, and the first (and only) Robots in Disguise-themed wave, Optimus Prime uses the new 2015 Kreon construction with the hollow waist-peg and "raised" hands.. He comes with a buildable parts rack on which to hang/store his extra pieces. Unlike the previous Custom Kreons, he no longer features a chromed helmet, and comes with an extra clear-plastic helmet, torso, legs, and his arms, plus a chromed Bazooka (originally from the Kre-O Battleship sets), and some kind of a dual pick-axe with a clear red staff.
Yet another Reveal the Shield redeco with the Motorbreath retooling, Convoy is cast in clear red and black plastic. He has been retooled to include a magnet in his right foot, allowing him to interact with Lost Age Battle Command Optimus Prime and Age of Extinction Stomp & Chomp Grimlock. Convoy was available at a variety of 2014 events, including on May 3 at a "Kids Walk" event at Fuji Speedway, in special packaging on May 16 at the "Transformers Celebration 2014" midnight event at the Sunshine City Toys"R"Us store in Ikebukuro, on June 15 at Tokyo Toy Show 2014, at the Aeon Mall in Kasukabe on July 19, and at the "Transformers Expo" event in Yokohama on August 9. Convoy was also available as one of three preorder bonuses for Cloud Roadbuster. 

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.
Unfortunately for both Takara and Hasbro, the Generation Two series of Transformers sold poorly, and Hasbro abandoned it after two years. There were toys planned that never saw release. Most of these were G1 combiner team recolors or recolors of recent figures. Four unreleased molds were released in the Machine Wars line, and four more resurfaced in the Robots In Disguise series.
In the series released by Marvel Comics, before the Great War broke out on Cybertron, the robot who would be Optimus Prime, before he received the Matrix of Leadership from Sentinel Prime, was a Transformer of note, displaying his skills in the Infraformers Sharpshooting Competition. When the war began, Prime quickly made a name for himself as a combat leader of the Autobots.

The lowest priced toys in the Armada line were three-packs of Mini-Cons. Each larger price point consisted of an Autobot or Decepticon who came with a Mini-Con partner. Mini-Cons could be used to unlock a variety of features on each larger robot, such as firing weapons, electronic lights and sounds, or alternate modes. Some three-pack Mini-Cons combined into other forms or had additional features. According to the storyline, Mini-Cons also enhanced the power of other Transformers, giving incentive to collect as many of them as possible.
Optimus Prime would also be a major character in Devil's Due Publishing's various G.I. Joe meets the Transformers series. Devil's Due Publishing does not address Prime's early years, save that he survived an assassination attempt by Bludgeon soon after receiving the Matrix. The traditional Ark storyline left the transformers crashed on Earth. In this series, instead of being reactivated by the Ark, the transformers and the ark were discovered by the terrorist organization called Cobra. The transformers inside were reformatted into Cobra vehicles, remotely controlled by the Televipers. Prime was turned into a Cobra Sentry Missile System tank, which was a 1985 Sears store exclusive red repaint of the HISS tank.[14] After an attack on a U.N. summit in Washington D.C., Optimus was able to get a message to Wheeljack, alerting G.I. Joe to where the Cobra base was hidden. Subsequently, he and the other captive Autobots and Decepticons broke free. After the ensuing battle, Optimus fought and defeated his enemy Megatron. After Megatron's defeat, the transformers returned to Cybertron in a second Ark Class vessel, but not before giving their human allies the ability to build and use mecha based on Transformers technology.
Megatron came upon Optimus and challenged his old foe to a duel. Optimus managed to gain the upper hand, but hesitated to deliver the killing blow when he discovered that Megatron had married the Matrix to his spark, corrupting it. Several Decepticons then swarmed Optimus, allowing Megatron to blast a hole through his chest. Dead and defeated, Optimus plummeted down into the bowels of Cybertron. Pax Megatronus Rodimus and Duke travelled far beneath Cybertron, where they discovered Ultra Magnus- the Autobot god of death -carrying Optimus's body away. Earth: R.I.P.
The figure also comes with two gun accessories, the "Eliminator Gun" and "Assault Blaster", which combine into the "Mega Striker", a rifle that closely resembles the one used in Dark of the Moon. The separate guns also have a MechTech-style transformation, and pulling a lever transforms them into alternate crossbow-like shapes. In "battle vehicle mode", the sides of the truck are rotated up, and the guns can be attached by small pegs to holes in the modified smokestacks, or they can plugged into any of the standard connection points with their 5mm posts... except the ones on the hinge behind the cab, since those are supposed to be for his Energon battle blades.
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.

Most notably in terms of new tooling, the panels on the undersides of Powermaster Optimus Prime's forearms feature slots under the fists, which allow the guns to tab in and be held much more stably than with Ultra Magnus. And due to the amount of empty space in the cab area in vehicle mode, Powermaster Prime can fully transform without the need to remove his head.

Another game was released for the Sony PlayStation 2 by Atari; simply titled as Transformers, it was based on The Transformers: Armada. The game's reception was mixed, particularly due to the popularity of a PS2 Transformers game released at the same time for a Japanese-exclusive market, though the Armada game was of a higher quality and featured much better gameplay. The game not released in America was based on the Generation 1 storylines.


There is one aspect not looked at in the price and that is the shift to model building vs. creation leading to a change in the utility of the pieces. I seem to need many more sets to get a useful variety of pieces these days as many of the sets contain a lot of pieces that are very specific to the needs of the set and are less useful when one wants to create their own designs. It would be a fascinating addition to rate each of the block types on its utility, perhaps by its prevalence in other sets, and then assess each set on its total utility score. So then the question is how many sets would you need to by to achieve different levels of utility and how has this changed over time.
A limited edition of the Optimus Prime toy sold as a mail-away exclusive by PepsiCo was made available in North America in 1985. This version of the figure came with a small fold-out leaflet glued to the top-right of the packaging, which contained two Pepsi logo stickers for the buyer to attach to Prime, mid-way through the traditional silver-and-blue stripe on his trailer. Canada also got a version of this promotional figure, but with much larger stickers that were the full length and height of the trailer. This promotion would go on to serve as the inspiration for the Japanese character of Pepsi Convoy, who would in turn be released by Hasbro as a new "Pepsi Optimus Prime" in 2007.

The trailer unfolds to form a battle station bristling with many firing weapons. Primarily, it can fire an air-powered missile launcher, a ripple rocket launcher with 5 missiles that can be launched individually (this turret can also be mounted in Laser Prime's hand) and a 'disc launcher', that fired several blue plastic discs adorned with the Generation 2 Autobot sigil. This disc launcher is the only weapon that can be used in vehicle mode.

Available only with the Bot Shots Dragon Track set, this version of Optimus Prime is a new mold, changing from a robot form resembling Generation 1 Optimus Prime, into a truck with a rocket exhaust molded into the back of its trailer. As a Flip Shot, he, er, flips up when auto-transforming. He comes with a launcher that can be connected to the track, as well as Flip Shot Megatron and his launcher.


Available in a two pack set with Battle Changer Megatron, this Optimus is largely the same as as the single release, with some minor differences. He uses a new "double harness" piece on his torso instead of using two harnesses, leaving more space for his head to grip the neck-post. He also has different windshield decals, and his reds and blues are slightly darker. And, most obviously, he has an additional buildable trailer, though it doesn't really attach to the truck mode in any meaningful way.
Optimus Prime appears in the Transformers live-action film series as the leader of the Autobots and one of the main protagonists. In the first three films, he is able to transform into a conventional Peterbilt 379 cab, rather than the cab over design of his original Generation 1 body. In Transformers: Dark of the Moon, he gains a first generation-style trailer form before changing into a 2014 Western Star 5700 Concept.[29] Also straying from the G1 design, Prime's vehicle mode is now decorated with red flames painted onto a blue body à la Rodimus Prime, his Generation 1 successor. The reason for the change was due to Director Michael Bay's decree that mass displacement does not occur when they transform, requiring Optimus's vehicle form to have more mass to achieve the desired size in his robot form.
I have to disagree. Look at our planet. Jagged and rigid is an aspect of primitive technology. Smooth, compact, and protected is an aspect of futuristic technology. Transformers should look more advanced than what we hsve, nor technologically regressive. They have better scientists and millennia of knowledge compared to us. Smooth designs like Knight's are the only ones that make realistic sense in that context of technological progression, even as a life form.
The original Optimus Prime toy started life as the Diaclone toy, "Battle Convoy", created by a team of Takara designers who came on board when the original designer fell behind. This team included Hiroyuki Obara (listed as the sole creator on the toy's patent) and famed mecha designer Shōji Kawamori. The toy transforms into two major components; the first component being a red and blue White Freightliner WFT-8664T cabover semi-trailer truck partially composed of die-cast metal, and the second component being a large silver trailer of currently-undetermined model.
