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.
A nice article but I see a few flaws. First of all if the distribution of LEGO sizes/prices is increasingly skewed it is better to either split the sample or look at medians or rolling medians than averages. Secondly, this is a perfect case to run a regression panel regression with time dummies to see both the impact of time and the impact of size on the prices.

Interesting work but I would like to know whether you would find the amount of new sets offered in toto has changed over the survey period. Is there an economy of scale at work? This seems to have two implications: first, the number of units for a particular set may have increased thereby affecting the price of all sets belonging to that class (but doubtful you could find exactly how many Death Star sets were produced in relation to, say, hogwarts castles); second, the popularity of certain set classes may affect what kinds of sets are available. Like with language, we are all confined to use the words we know. And so with Lego, set designers are confined to use what’s economical, unless, of course, the design calls for new styled pieces. These relations are difficult to grasp in statistical analyses, but would seem to play a role in price steering.


The Premium Series Optimus Prime is both a retool and a redeco of the Leader Class Optimus Prime toy. The major selling point is a more movie-accurate headsculpt with longer ears and detailing based on the final CG head design, and a flip-out energy sword to replace the ion blaster that was included with previous versions of the toy. A smaller laser is seen when it flips out with the sword. This energy sword is detachable and attaches where the Ion Blaster did, compatible with non-premium Optimus Prime leader class based releases. Because his ears are much longer, the truck roof panel that hides his head now has two holes cut into so the head can fit inside the cabin.


In Spotlight: Doubledealer, Hot Rod's search was interrupted by Dealer's arrival on Earth, with orders for Hot Rod: find the Magnificence and use it to learn what they could about the Expansion. Hot Rod took Dealer to his hiding spot, which turned out to be the planet where they first found the device. As Dealer and Hot Rod closed on the Magnificence, he went over his first visit to the planet in his mind, and how things could have gone so wrong. Eventually he began to have suspicions, and upon locating the Magnificence, asked it the question that haunted him: had Dealer betrayed him? Sadly, it revealed the truth, and Hot Rod was forced to kill Dealer as the traitor attacked. Looking down on his remains, Hot Rod realized the truth had been staring him in the face, he just had not wanted to accept it. He then used the Magnificence to find out all he could about the Expansion, and relayed the information to the Autobots.
The values started becoming inconsistent and skewed in Generation 2 and Beast Wars, when Hasbro apparently thought no child will ever want a toy that is described as anything less than perfect. Thus it became rarer and rarer to see any low numbers. Most characters' numbers hardly ever dipped below 8, the Go-Bot version of Optimus Prime was the first character to have all values at 10, a trend that would repeat for most "leader" characters. When even more powerful versions of the Optimus Primal toy (such as Optimal Optimus) were introduced, Hasbro even invented a "10+" rating in an attempt to keep increasing the power levels. With the Transformers: Cybertron line a few characters even got "Unknown" and "Infinity" ratings.
Just which character this toy represents is up for debate. The toy's bio claims he used to turn into a tractor-trailer (indicating Optimus Prime), but considering the timeframe of when they were written and the whole lack of a stance on who Primal "was" before the show and blah blah blah... it's just easier to file this under the same iffiness as the original toy bios set on modern Earth and leave it at that.
Optimus Prime was blasted into pieces by Dragon Megatron. Beast Wars Metals #5 Fortunately, his spark remained perfectly intact—in the remains of his Matrix-shaped spark chamber. Megatron was going to destroy Prime's spark, but Cheetor (now in his Transmetal body) saved it. Prime's spark was eventually swallowed by Optimus Primal, who was upgraded into Optimal Optimus by doing so.

A five-inch tall, non-transforming highly-articulated PVC figure of Optimus Prime in his Super Mode was the eighth entry in Takara's Mega Super Collection Figure series. In addition to a non-transforming figurine of Sparkplug, Optimus comes with two sets of alternate hands—one set with spread palms, one curled into fists—and is armed with his Convoy Gun, which can either peg into his right fist (and only his right fist) or onto his back.
Optimus became the leader of the Autobots for a time, then disappeared, leaving his people to be ruled tyrannically by Megatron.Targetmasters Megatron never stopped seeking out his old foe, rewarding any of his troops that provided him with information that could lead to Optimus's whereabouts. The Golden Boys As for the Autobots, they were uncertain exactly as to why Optimus had disappeared; some believed Optimus had simply abandoned his troops, while other believed he was fulfilling some greater purpose and would return to them in their hour of need. Ultimately, it was Snake-Eyes and Duke who found the Autobot leader, lost in the void between dimensions. Form Follows Function There, the three of them became ensnared by the Quintessons. They escaped the extra-dimensional entities' mind-probe and made their way back to normal space. En route, Optimus learned from Duke that Bumblebee had traveled to Earth and met his demise there. His human companions went off to help their friends on Cybertron, while Optimus headed for T.H.E. P.I.T. on Earth, eviscerating numerous Coltonbolt satellites as he entered the atmosphere.

Optimus Prime Special Color (オプティマスプライムクリアVer, Optimus Prime Clear Ver) was only available blindpacked as part of TakaraTomy's EZ Collection Vol. 3. It is a clear version of the Revenge of the Fallen mold, casted in (entirely colorless) clear plastic with opaque paint operations (which is the same paint mask from the original Legends Class toy albeit slightly darker) on the details. This redeco also uses the slightly small fuel tank/elbow tabs from the Battle Damaged release.

With the data from the piece price evaluations I was able to also evaluate the average size of LEGO sets each year. As you can see on the chart below, the average size of sets released each year stayed somewhat constant from 1980-1990 until around 2000 which set sizes started to increase. The average set size seems to have peaked in 2008 (which saw the release of the Taj Mahal), but since then it hasn’t fallen to its pre-2000 levels. It seems to have found a new normal around 300 pieces.
The Japanese release of Powermaster Optimus Prime actually represented a new character named Ginrai, and featured several retools: the cab featured die-cast metal, shortened smokestacks, vacuum-metalized plastic and clear blue windows, while the trailer was given retractable super robot fists. This Japanese version was eventually issued by Hasbro in 2003 as part of the Commemorative Series collection (see below).
This is a redeco of Ultimate Optimus Prime. While Prime himself only features a red grill, the trailer has been extensively redecoed, with an ornate golden Chinese dragon being painted on the trailer panels, and the various gray parts of the trailer panels, armor, and cannon being replaced by blue, red, gold, and burgundy. The toy was released as a "Year of the Dragon" Special Edition in 2012, since the Chinese Zodiac sign for that year is the Dragon.
All of the Tiny Titans were sold blindpacked. However: there's a tiny clear window in the back to peek at the item inside, making the task of getting the ones you want easier. Every collectible card included in Tiny Titans has a scannable insignia sticker on it. Scanning the badge unlocks a random amount of Energon "currency" and a randomized bonus power-up item, and can only be scanned once per day. It's honestly quicker and less redundant to say which toys don't have this feature.
Two custom-made pieces (presented in robot and vehicle mode) by the Hasbro Transformers team as the grand prize for G4TV and Jumpcut's contest for fans to remix selected Transformers clips. Won by TFW2005.com member James Zahn, this one of a kind (well, two of a kind) piece is a almost fully vacuum-metallized Leader class Optimus Prime in red, silver and blue (based heavily upon Generation One Optimus Prime), presented with a custom display base with an embossed silver Autobot insignia and a perspex display case.
As battles between numerous different Primes and Megatrons erupted quite literally all across time and space, another member of the Convoy Aggregate was later seen battling Starscream, who had been empowered by Megatron to serve as leader of his Questors. This Prime was so surprised by Starscream's uncharacteristic sports car alternate mode that he left himself open for a blast from Starscream's Retroactive Nullifer cannon, which erased him from the timestream. As he faded out of existence, Prime responded to Starscream's taunts about the death of the Alternity by telling him that they were already well aware of their prophesied end and were well prepared. Foreshadows
He includes the Sword of Judgment and Sentinel Shield accessories, which he can respectively wield and mount on his left forearm, all via 6mm post. In truck mode, the sword is stored underneath, while the shield mounts onto the trailer hitch. The sword also features a 5mm post on its hilt. Interestingly, the truck mode is able to pull G1 Optimus Prime's trailer.

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.
GT-R Prime was racing against GT-R Saber and GT-R Maximus when they were rudely interrupted by GT-R Megatron, a ruthless racer out to prove his worth by defeating all others. A fight broke out, but Prime interrupted it and convinced Megatron that they all shared the same need for speed, persuading him to settle things with a race instead. Transformers GT: Mission GT-R
The voice actor drama was written for OFTCC 2004 by Simon Furman, set after the events in the comics. Among those taken from their world via teleportation beam by Unicron and his Decepticon minions were Spy Changers Optimus Prime, Prowl, Ultra Magnus, and Ironhide. The Autobot forces opposing Unicron attempted to deflect a beam, leaving them all trapped on an uninhabited ice-world. The Autobot forces teamed up to overcome the Decepticons led by Reptilion. The Autobots were then, presumably, returned to their own worlds.
Revenge of the Fallen Legends class Optimus Prime is an all-new, much more accurate mold compared to the 2007 Legends class Prime, having a much greater accuracy in both robot and vehicle mode. In particular, his vehicle mode isn't inexplicably missing one smokestack like the 2007 toy. It should be noted that he was molded in only one paintable plastic color, with red and blue deco patterns decked on it. The top of the truck's bunk (ending up on his back in robot mode) has a slot to combine with Jetfire. For some reason, this isn't mentioned in the instructions, though they're hardly needed.
A Deluxe sized version of Energon Optimus Prime. Looks like a smaller version of the Leader class toy, without any trailer or drones. Can Powerlinx with other Energon Autobot toys. This toy was a Toys-R-Us store exclusive in the U.S. and was packaged together with a downsized Energon Megatron. In Japan this toy was packaged together with Kicker and a Star Saber accessory.
In the alternate universe of the 2003–2004 toyline and series, Transformers: Energon, Rodimus (lacking the "Prime" suffix in English, but still called Rodimus Convoy in Japan) was a great leader on Cybertron ages in the past and was viewed as a hero by many, including similar character Hot Shot. Desiring to escape the war that had consumed the planet, Rodimus departed Cybertron with a contingent of like-minded troops, most of whom settled on an alien planetoid and became the energon-mining Omnicons. Still, Rodimus continued on his journey with Prowl and Landmine, carrying the "flag of peace" from world to world.

A non-transforming model kit of Optimus Prime by Takara Tomy, sold exclusively in Japan. The kit comes with a pre-assembled inner frame that features a high rate of poseability similar to Master Grade Gundam model kits. The kit comes with two swords and two different sets of attachments for them: one set for the forearms and the other to replace the hands. Pre-ordered units of the first batch came with battle hooks.[138]
Optimus foiled Megatron's attack on 21st century Tokyo after informing his old foe that wherever he would pop up, the Autobots would be there to thwart his evil intentions. Henkei! Henkei! volume 1 Optimus and Bumblebee later intervened when Astrotrain attacked Shinjuku Station, using their bodies to shield nearby humans from the destruction the triple-changer brought about. They were unaware that Astrotrain's rampage was really a distraction staged to keep their attention away from Megatron's gathering of energon cubes nearby. Henkei! Henkei! volume 2 Optimus continued to do battle against Astrotrain until Rodimus showed up to provide the Autobots with additional firepower. Henkei! Henkei! volume 3
The largest Action Master set, this incarnation of Optimus Prime is a non-transforming action figure which comes with the "Armored Convoy", a large, heavily armed tractor trailer. The cab of the truck transforms into a small jet that can seat one Action Master figure, while the trailer itself converts into a larger battle station with turrets that several Action Masters can man. The sculpt of the Prime figure itself is closely based on his character model, albeit with a coloration that seems to have been based at least partially on the small robot form of his Powermaster body.
Optimus has the ability to change any part of his robotic body into a tool or gadget. He has swing lines in his wrists. His wrists can also fire capture bolas. His arsenal includes a grappler, fire extinguisher and a negative friction spray. It is interesting that, unlike all the previous series, his face can almost always be seen, because his mouthplate is retractable like in the 2007 live action film.

In Axiom Nexus, General Optimus Prime found himself inducted into the Convoy, a group of Optimus Primes and their kin dedicated to safeguarding the multiverse. While the other Convoy members tended to stay in the upper reaches of Axiom Nexus, the General was able to use his unusual appearance for an Optimus Prime to venture in the Offworlder zones without suspicion, a great help to Offworlder Zone Security Administration Commander Cheetor. The General was also assisted in his new mission by his longtime scout, Sergeant Hound. General Optimus Prime profile card Sgt. Hound profile card


For Transformers: Age of Extinction, Optimus Prime initially transforms into a rusty 1973 Marmon semi cab-over truck and later on a new alternate mode in a blue and red Western Star 5700 Custom semi-truck.[31][32] After humanity turns on all Transformers, regardless of faction, Optimus and the other Autobots go into hiding. Eventually, they find themselves being hunted by a rogue organization called Cemetery Wind. Optimus is severely injured in a trap set by the group, while many of the other Autobots, including Ratchet and Leadfoot, are slain. An inventor, Cade Yeager, comes to Prime's aid and helps restore his health. After uniting with a small band of Autobots, Optimus faces Lockdown, a ruthless bounty hunter allied with the humans, and KSI, an organization that produces man-made Transformers. Optimus is captured by Lockdown, but the Autobots rescue him. Optimus is quickly losing faith in humanity, but at the urging of Cade, chooses to stay and fight a resurrected Megatron and his new army. Prime awakens the ancient Dinobots, and rides a newly tamed Grimlock into battle through Hong Kong. He kills Lockdown and Harold Attinger at the film's climax as revenge for killing many of his friends, including Ratchet and Leadfoot. At the end of the film, he leaves Earth and flies off into deep space, seeking to find out the truth about his mysterious Creators.[33][34]
In one possible scenario, Optimus was surprised to see Beachcomber return to Autobot headquarters soon after his departure. Beachcomber informed Optimus that he had uncovered the Decepticon's newest hidden fortress, and he suspected that the Decepticons were up to something big. Optimus sent out Beachcomber once more, this time along with Powerglide and Windcharger to investigate the Decepticons' plot further.

This mold was redecoed by Takara in 2000 as Car Robots Black Convoy. The following year, it was released by Hasbro as Black Convoy's 2001 Robots in Disguise franchise counterpart, Scourge, with retooled discs that lacked the Autobot insignia. Following this, the next use of the mold was planned to be Universe Toxitron, which ended up being canceled. The modified tooling was also used when Laser Prime was reissued by Takara in 2006 with a modified deco (see below), and for the e-Hobby exclusive Laser Ultra Magnus that accompanied the reissue's release. In 2015, Platinum Edition Year of the Goat Optimus Prime, another repaint version, comes with partially transparent plastic torso.

Part of the first wave of TakaraTomy Lost Age: Movie Advanced toys, this Japanese-exclusive redeco of 2007 Transformers Protoform Optimus Prime is given a Generation 1-styled color scheme (which is also based on his appearances in IDW's Transformers: Foundation comic-book mini-series). Protoform Optimus Prime transforms into his "entry" mode. This mode somewhat resembles a cybertronic truck, with false wheels sculpted onto the sides, and Optimus Prime's trademark windows in front. His now-blue flame decoration piece fits to the back of the "vehicle", creating the illusion of a flaming comet's tail (Not sure if this was mean to represent his jetpack blast effect or his atmospheric entry heat effect, which is for no reason: entirely blue instead of hot red). The bottom of the vehicle has small wheels to roll the toy across smooth surfaces.
