Released as part of the Energon Igniters Power Plus Series subline, this Optimus Prime is a Scout-sized mold that converts from robot to truck based on his appearance in Age of Extinction in just a few steps. His only articulation is the swiveling upper arms & pivoting arm joints, and his fuel tanks also doubles as a flip-out cannons, activated in vehicle mode. As with all Nitro and Power Plus figures, Optimus also comes with an energon core, which allows his vehicle mode to propel forwards.
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.
In Transformers: Decepticons, Optimus Prime lands on Earth along with the other Autobots to stop the Decepticons. Optimus does not appear until Megatron is released and Starscream escapes with the Allspark. Optimus fights Megatron, but is defeated and is killed while Megatron gives chase to his traitorous second-in-command. In the 2009 Revenge of the Fallen video game by Activision, Optimus Prime is among the playable characters.[20]

Hot Rod has a youthful attitude, and serves as an older brother figure to Daniel Witwicky, son of Autobot ally Spike Witwicky. He has a sort of mentor-student relationship with the veteran Autobot Kup. He was also good friends with Springer and Arcee. Later in life, he temporarily bears the Autobot Matrix of Leadership and becomes Rodimus Prime (Rodimus Convoy in Japan), and new leader of the Autobots.
As leader of the Autobots, Prime headed up their mission to search for new sources of energy to revitalize the depleted Cybertron. Optimus vowed to Elita that he would return from his mission for her, but just before the launch of the Ark, Optimus was mistakenly led to believe that Elita was killed. Shortly after its launch, the Autobots' craft was attacked by the Decepticons' space cruiser, the Nemesis, and boarded by Megatron and the Decepticons. In the ensuing struggle, the G-forces of a nearby planet pulled both craft down, and the Autobots' ship crashed into a volcano, thrusting all the occupants into emergency stasis. Four million years later, in the Earth year 1984 A.D., a volcanic eruption jarred the ship's computer, Teletraan I, back to life. The computer reactivated the Decepticons, programming them with new Earth-based disguise modes. As a parting gesture, Starscream fired upon the Autobot ship, creating a landslide. The vibrations from that landslide knocked Prime into the path of the computer's restoration beam, restoring him to life, thus beginning the war anew on Earth.

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.
In this set, both the buildable Optimus Prime and the included Kreon figure are in the style of Beast Hunters Optimus Prime. In addition to the robot mode having a buildable shield and sword, both it and the vehicle build have two firing missile launchers. Additionally, four hands are included, with two possibilities for each arm. These Optimus Primes come with a buildable Predacon beast Lazerback and an Energon Kicker Kreon.
Partially constructed of die-cast metal, this small three inch figurine of Optimus Prime has a CGI-accurate sculpt compared to the larger toys, owing to the fact it does not need to transform at all. He is sculpted with his Ion Blaster in his right fist, and is articulated at the neck, shoulders and waist. He comes with a small movie-style Autobot sigil display stand.

In 2016, the figure saw re-release with the Combiner Force packaging. Being the tenth use of the sculpt at this point, some instances of mold deterioration have affected the figure, including: the vehicle front's bumper (which affects the space on the head/front bumper transformation), the headlights, and/or the legs, and the hole on the left shoulder is also prone to develop a stress mark due to the right shoulder's slightly "thickened" peg. Although the re-released badge didn't seem to unlock Optimus Prime after it was scanned, a later update to the game amended this.


The energy of the explosion absorbed by the virus, the Autobots dug themselves out and set about recovering their fellows whom Megatron had used to power the cyber-virus in its early stages. Ironhide passed on a message from Megatron — there was a surprise in store for the Autobot leader. Optimus and some Autobots including Superion sped to San Francisco, where Megatron had unleashed Devastator. As Prime battled Megatron, he took time to save three humans who were threatened by falling debris, only for the humans to turn on him. The defeat of Superion turned the tide of the battle against the Autobots. Prime Directive #4
Rounding out a bumper year of Japanese-exclusive Generation 1 Optimus Primes, the Takara-licensed Kawada brand Diablock Convoy is a fully transformable Lego-style block building figure similar in premise to the earlier American Built to Rule sets. The Diablock figure, however, easily outstrips the Built to Rule sets by both being an accurate representation of the toy on which it is based, and being able to transform between modes without having to be partially disassembled and put back together first.
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.
When Highbrow was captured by the Decepticon leader Scorponok, Optimus Prime agreed to surrender himself to ensure his fellow Autobot's safety. Naturally, though, Prime did not expect Scorponok to hold up his end of the bargain, and he had Hosehead and Fizzle rescue Highbrow while he allowed himself to be imprisoned. Their mission successful, Hosehead and Fizzle then sprang Prime from his cell, and the team beat a hasty retreat. Autobot Hostage
Another version of Prime was also available in the second wave of the Smallest Transforming Transformers series as a chase figure. This almost entirely white version of the figure is clearly based on the version of the original Prime cab robot used in the Generation 1 Ultra Magnus figure, but was nonetheless sold as Optimus Prime for the Smallest line.
Prime comes with all the accessories of his previous release, although his ever-changing ion blaster is now somewhat confusingly cast in blue plastic. He features one major additional accessory: an electronic display base sculpted with the image of the Matrix and the Autobot insignia. Pressing the insignia's crest triggers a series of electronic soundbytes, mostly quotes from the movie recited not by original actor Peter Cullen, but by Hasbro's in-house actor, Ron Hayden: "Autobots, transform and roll out!", "I want you to make a special run to Autobot City," "Megatron must be stopped!", "All we need is a little energon, and a lot of luck," and two samples of the classic transformation sound effect, one ascending, one descending.

Optimus Prime's body was hauled out of the Arctic Ocean by the US military. While a terrorist organization run by the enigmatic Lazarus was able to seize control of several of the other Transformers that fell back to Earth, the military worked unsuccessfully to reactivate Prime. They eventually called in Spike Witwicky. Prime Directive #1 Spike was forced by the project chief, General Robert Hallo, to use his piece of the Matrix to reactivate Prime. Functional again, Prime used the Matrix to reactivate more of his fallen comrades. Prime Directive #2
Optimus Prime comes with many accessories in addition to the aforementioned Matrix, including the character's traditional laser rifle, now termed (and henceforth known as) an ion blaster. The initial release of the figure cast the ion blaster in grey plastic, but later assortments recast it in its more familiar black coloration. Other accessories include a transparent orange energon-axe that plugs into either wrist when Prime's fist is retracted, and even a non-transforming gun mode Megatron weapon, with removable stock, silencer and scope accessories, in homage to several instances in the Generation 1 cartoon when Prime was forced to wield his enemy. Pack-in bonuses that came with the figure included an inner cardboard tray illustrated to resemble the interior of Prime's Combat Deck, and in later releases, a small poster drawn by Pat Lee.
This retool of Revenge of the Fallen Leader-Class Optimus Prime features the head from Buster Optimus Prime and has had his blades replaced with semi-articulated Battle Hooks for face-destroying action! He has a darker paint job and sports black splotches on his body and head to signify battle damage. However, due to these extra "battle damage" paint applications, some other paint applications that were present on the Revenge of the Fallen release were omitted. He also sports a new voice box in robot mode, replacing the infamous "I am Optimus Prime!" with "We must stop the Decepticons!" The international release, however, retains the same abbreviated "Optimus Prime" sound clip as the original release. To the annoyance of many fans, this version was the main version released just about anywhere outside the United States (all of Canada, Latin America, Europe, and Asia). The box also mentions racing sounds, which may or may not be referring to the button-activated diesel engine noises carried over from the Revenge of the Fallen version of the figure.
On the day before the Transformers GT began, GT-R Prime found himself racing with GT-R Saber when they were both out for a test run. Though Misaki warned him not to get too invested in a practice race, Prime took the challenge seriously and won the race by briefly transforming into robot mode, thus tricking Saber into slowing down in anticipation of a fight. Test Run Battle! –Prelude– Prime earned the pole position for the Transformers GT, but this combined with his victory over Saber made him overconfident, and he was unprepared when Saber attacked him immediately as the race began and sent him flying. First Fast Attack! –Whoever Strikes First Wins– GT-R Megatron also targeted Prime during the course of the race, seeing him as his fated rival. One Shot and One Kill!! –Finishing Blow–

If the Autobots went along with Prowl’s strategy, the resulting heat from the explosion caused the Autobots’ circuits to overheat, rendering them unconscious. Upon reawakening, the Autobots found themselves captives of Megatron, who informed them that their fellow Autobots would soon perish, and that the humans would be conquered by the Decepticons shortly after.
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
