One more thought: LEGO is a Danish company. The fluctuations in the price of LEGO such as the big bump around 1985-7 in Figures 1 and 2 could be because of a change in exchange rates. The conversion rate between the Danish Kronor and the US$ went from over 10 in 83 and 84 to less than 7 in 86 and 87. LEGO might have been slow to respond to changes in exchange rates, leading to the temporary bump. If you’d like to share data we can redo your graphs in DKK.
In the Autobot Campaign, Optimus Prime provides intelligence and missions to Bumblebee in his search for the Allspark. Eventually, the clues lead the Autobot to Sam Witwicky. After saving Sam from Barricade, Bumblebee finally completes preparations for the Autobots to arrive on Earth. Once on Earth and having informed the two teenagers of their mission, Prime and the Autobots are discovered by Sector 7. Optimus sends Jazz on a high-speed destruction distraction mission, then sends Ironhide to rescue Jazz from a double-threat posed by the government agents and various Decepticon scouts. When Bumblebee is captured, Prime transforms and chases the chopper which from which the small Autobot is tied. After a lengthy chase, Prime manages to catch the net, only to be thrown off by another Cybertronian meteor. As Bumblebee is carried away, Optimus promises he will not fail him again. Jazz informs him that the meteor is not an Autobot. Prime confronts the new threat, who turns out to be the Decepticon Triple Changer Shockwave. The two battle it out across Tranquility before Optimus finally destroys him. During the battle, Optimus overhears Starscream's transmission revealing the location of the Allspark. Optimus then returns to an intel role as he guides Bumblebee in his mission to retrieve the Allspark from Hoover Dam. Unfortunately, the Decepticons manage to free Megatron, leading to the final battle in Mission City. As the Autobots battle it out with the Decepticons to protect Sam and the Allspark, things seem to take a turn for the worse as Megatron finally arrives. Before he can claim the Allspark, Optimus attacks him. Optimus defeats Megatron and leaves him on the ground, seemingly devoid of life. However, just as Sam is giving the Allspark to Optimus, Megatron awakens, leaping at Optimus with his chain-flail out, making one last attempt at defeating his adversary. Optimus grabs the chain, pulling Megatron in closer, and, with the Allspark clutched in his fist, delivers a punch through Megatron's spark, killing him. Optimus reflects on the losses and rewards of this battle, as the Autobots have a new home, but many were killed in the battle. The story ends with Optimus and the Autobots choosing to remain in Earth, proclaiming it as their new home.
After the successful Armada toy line, Hasbro/Takara introduced Transformers: Energon. The accompanying television series program was a direct continuation of the events of Transformers: Armada and featured many of the same characters in new forms. This was reflected in the toy line, as characters such as Hot Shot, Jetfire, Optimus Prime and Megatron were all released with entirely new molds.
Came with the Mini-Con Sparkplug. Could combine with Armada Jetfire (and its repaints) and/or Armada Overload (and its repaints). The trailer could convert into a base for Mini-Cons. In Japan a gold chrome edition of this toy was released as a Lucky Draw special. With its trailer the vehicle mode of this toy bears a great resemblance to G1 Star Convoy. According to the Armada video game Armada Optimus Prime is supposed to be 22 feet 10 inches tall (696 cm tall) and the toy is 17.5 cm tall. So that's a scale of 1:40.[55]
This golden chromed redeco of the Super class Optimus Prime figure was initially offered as a prize to five lucky winners of a colouring contest held in the pages of the TV Magazine. Additional units were later given away via in-store draws at Toys"R"Us Japan; precisely how many is unknown, but the regularity with which the toy appeared on auction sites throughout 2005 suggests it was quite a few.

Prime: First Edition Matrix of Leadership Optimus Prime converts from robot mode to his truck mode. He comes with a gun than he can wield with his hands, as well as peg onto his hitch in vehicle mode, with different pegs for either configuration. Similar to a previous Optimus Prime toy, he features some faux-kibble in the form of his actual windshield chest being covered by sculpted panels featuring his characteristic windshield-chest. His arms are slightly longer than his original design's arms.


This Voyager-sized Optimus Prime is an all new mold (with a similar transformation scheme to Age of Extinction Voyager Class Galvatron, notably the shoulders, rooftop backpack, and the leg/wheels combo) based on his Leader Class figure. He features a similar but different transformation scheme, which results in a somewhat clean robot mode, although most of his vehicle kibble hangs on his back. He also features the sword & the shield based on his final design in the movie, albeit the sword being painted similarly to the Armor Knight Optimus Prime's sword. His Sword can store underneath his Vehicle mode or his robot mode backpack, while the shield can be stored on the truck's fifth wheel hitch, which can also tow the trailer included from the Japanese exclusive Mechtech Voyager. Although the pectoral armor can be slightly pushed up a little bit further, the pieces have to actually stop at where the rectangular pegholes are located.
Calibur Optimus Prime is a retool of the Armor Knight Optimus Prime figure, who is a retool of the original Age of Extinction Leader Class figure, with the fifth wheel hitch now forming his handheld shield based on the one used in Dark of the Moon, which results in a backpack-less robot mode. He also comes with an axe based on the one used in the third film.
This Walmart-exclusive redeco and retool of the 2010 Transformers toyline "Battle Blades" Optimus Prime toy features the Japanese release's hooks (instead of swords), plus an all-new mouthplate-less, mouthed face. As part of the set's lunar theme, reflections of stars are painted across his vehicle mode sides and on his windshield, with a sharp reflection of Earth's Moon in one of his windows. This time, his Matrix of Leadership is cast in orange plastic.
In the animated series, Optimus is able to fire short-range optic blasts, project holographic maps, and deploy hydro-foils, designed by Wheeljack, to traverse bodies of water with ease. In the animated series, Optimus was also given the ability to retract his right hand unit and replace it with a glowing axe.[7] Across the assorted continuities of the original Transformers universe, there have been various interpretations of Optimus Prime. One of Prime's most notable characteristics over all continuities his unswaying commitment to leadership by example. The animated series's version of Optimus Prime is depicted as a straightforward, wise, and upbeat battlefield general. Additionally, the animated series's version of Optimus dislikes rap music, putting him at odds with music-loving characters like Blaster and Jazz. In the Marvel Comics series, in addition to these characteristics, Prime is secretly plagued by self-doubt and a conflicted sense of pacifism that often makes him an extremely reluctant warrior.
Optimus Prime is usually depicted as being a member of an ancient Transformers race called the Dynasty of Primes, often receiving the title "The Last Prime" in many stories, in which he is depicted as being the last of the Primes. In the Transformers: Covenant of Primus, it was established that Optimus Prime was the last born of the original Thirteen Transformers. It was his unique spark and his inspiring reassurance that "All are One" that allowed the Primes to rally and succeed in their battle against the Chaos Bringer Unicron. When tragedy at last ended the era of the Primes and brought forth the new race of lesser descendant Transformers he alone chose to be reborn in the Well of All Sparks as one of them, that he might know them and their needs more completely. All memory of his past life gone, he took the name "Orion Pax" and sought his way like any other robot on the new world becoming Optimus Prime once more when receiving the Matrix of Leadership when Cybertron faced a new enemy in his former friend, Megatron and his army of followers, the Decepticons. This brings a Great War to their planet of Cybertron. Optimus's origins and personality can vary depending on which "universe" he's seen in. This origin is the most consistent between the various incarnations. Further differences are listed in the respective sections below.
Alternatively, the Autobots could concoct a plan where Optimus would pretend to allow himself to be taken prisoner, per Buddy’s suggestion. The Decepticons, fooled into thinking they’ve won, took Optimus Prime into their base. Having hidden his troops inside his trailer, Optimus and the Autobots then led a surprise attack on their unsuspecting foes.
There is also a smaller "Legends of Cybertron" Micro sized version of this Optimus Prime, without a trailer, and a Burger King Kid's Meal toy, again without a trailer. There is also a rotating sucker holder version of Cybertron Optimus Prime. Later releases of the Leader class and Micro class Optimus Prime were repainted in darker colors, supposedly representing Optimus Prime after the television story. This toy is called Galaxy Force Optimus Prime. A special metallic painted version of this toy was included with Megalo COnvoy in Japan.

This version of Leader-class Optimus Prime features a new lower face sculpt that lacks a faceplate, as well as the replacement of his fuel tank/exhaust assemblies with new, transforming versions that can combine into his ion blaster/barrage cannon. To the simultaneous pleasure and displeasure of people who had already purchased the first release of Leader-class Revenge of the Fallen Optimus Prime, Buster Optimus Prime features an extensive paint job that closely matches Prime's appearance on the big screen, including covering almost all of his grey plastic with silver paint or chrome, expanding and outlining all of the flame tampographs white for greater accuracy to ILM's computer model, and generally painting in small details, nooks and crannies that were neglected on the first release due to cost-cutting reasons. The red and blue plastic colors also vary from the original release, to better match his film appearance.
As the figurehead of the entire Transformers franchise, Optimus Prime has been on more pieces of merchandise than can be stated here. Several statues and busts of Optimus Prime as well as Optimus Prime themed objects have been released by various companies since the return of transformers to prominence, such as the "Optimus Prime Oral Care Station". Other figures released include various PVCs as part of Takara's "Super Collection Figure" line, which were later imported as part of Hasbro's "Heroes of Cybertron" series. Larger "Mega Collection Figure" PVCs were articulated and came with energy axe and gun figures.

Later, the Transformers were all transported to Cybertron by Primus to battle Unicron. Although Unicron had tainted the Matrix after killing Thunderwing, Prime managed to reacquire and purify the Matrix. Prime then sacrificed his life one more time to destroy Unicron by plunging the Matrix into his maw. The Powermaster process, however, had been working to fully bond Prime and Hi-Q. Prime's death completed the process, and the two minds and souls became one. Hi-Q's biomechanical body was stripped down and reconstructed by the Last Autobot, resurrecting Optimus Prime once more with the two minds now one. Prime rejoined the other Transformers on the planet Klo and routed Bludgeon's Decepticons.
Rodimus Prime/Minor is a character who appeared in season 3 of the Transformers Animated series. He is a homage to the Generation 1 version of the character Hot Rod.[17] He wields an energon bow-and-arrow weapon of his own design.[18] On March 31, 2009, Derrick J. Wyatt, lead Transformers Animated Character Designer posted an image of Rodimus' vehicle mode, which is described as a futuristic muscle car that is mostly based on a 2008 Dodge Challenger with some elements of a 1969 Ferrari Daytona. This was revealed at the 2009 BotCon where Hasbro released an action figure of Rodimus Minor. It showed that the 2008 Dodge Challenger parts of Rodimus' vehicle mode were mostly based on the back, top, and sides of the vehicle, while the 1969 Ferrari Daytona parts were found in the front of the vehicle, most notably, the headlights.
At one time, Optimus Prime worked alongside Megatron, bringing order throughout dimensions with the power of SARA. But Megatron was ambitious, and sought to use SARA's power for his own ends. Optimus saved Metropolis from Megatron's rebellion, and the Autobots banished Megatron from Metropolis. Optimus Prime remained behind as the leader of the Autobots. Fate As head of the space-time guardians residing in Cloud World's Metropolis, he was a valiant and powerful leader who commanded the utmost respect from his subordinates. Optimus Prime stood for peace and freedom for all sentient beings in all of time and space. His sense of responsibility in this regard was a bit too great for his own good, as it often left him worrying about things outside of his control.
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.
Hybrid Style Optimus Prime is an insanely detailed and complex transforming toy, created under the supervision of famed mecha designer Shōji Kawamori. Standing only three and three-quarter inches tall in robot mode, the figure is partially constructed from die-cast metal and features one of the most complex transformation sequences ever seen on a Transformers figure of its size. Alas, the small size of the figure also works against it, as it required several design concessions that resulted in (if we're being nice about it) an unimpressive cab mode.
It may be that the price of an individual brick has gone down over time, but what does it matter if the size of the bricks has decreased overtime? Sure, the average number of pieces in a set has increased, but how many of those pieces are tiny details? To answer this question, I compiled all the weight data on brickset.com and compared the sets by their price per gram in a similar fashion to how I compared them by price of piece. Below is the chart of my results (prices are in US dollars).
In another possible sequence of events, the trio returned to Autobot headquarters to relate their findings to Optimus Prime. The Decepticons planned to use a Destruction Beam to create a fault line near Center City, which would in turn be exploited by Rumble’s earthquake-inducing abilities to destroy the entire area. The Autobots then decided to split up in two groups, one to attack the Decepticons’ fortress, the other to stop Rumble in Center City. Optimus headed the lead team.
Part of the first wave of Mini-Con Battle Pack figures, this Optimus Prime figure is a new mold, about the size of a Scout Class figure (In Optimus' case, the size of Cyberverse Commander figure), and scaled with Legion Class figures. Its transformation scheme also takes some cues from the Legion Class figure. Battle Pack Optimus Prime also features a transparent orange battle axe & armor pieces, although the chest armor/flip-up mask piece is needed to be assembled first. The included pieces can be combined into a clawed battle axe, or attached to his body to form his armor (although the flip-up mask can restrict his head articulation). Optimus Prime can totally wield the axe dual-handed. As an undocumented feature, the axe can be stored on his truck mode with the tab featured on Prime's right shoulder.
A redeco of Legends Optimus Prime replacing his red plastic with more blue and silver, but sprucing things up a bit with red flame paint operations. Defender Optimus Prime (ディフェンダーオプティマスプライム) was only available in Japan as part of their Transformers Animated promotion in March 2010. It was given away for free to customers who purchased Animated merchandise at Edion, Bic Camera and Yodobashi Camera stores.
Alternity Convoy transforms into a 1:32 scale Nissan GT-R, featuring die-cast metal parts, an opening hood, trunk and doors, as well as an interior, complete with his feet and thighs being sculpted to form the back seats. This complex figure stands at 6.5" tall, and is armed with a pair of blasters on each arm. In the hyper-dimensional world of the oft-confusing Alternity fiction, this figure specifically represents the Optimus Prime of universal stream Primax 903.0 Beta.

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
