The first Nightwatch Optimus Prime is an extensive redeco of the previously released Leader-class Optimus Prime, replacing most of his red and blue with different shades of blue and black. In fact, he resembles the original Diaclone Powered Convoy color scheme of Generation One Ultra Magnus's truck cab. The previously blue and red flames have been replaced with silver flames, as has various other decos, replaced by copper.
Armada Built to Rule Optimus Prime transforms into a fair approximation of his vehicle mode, but the robot mode is quite inaccurate, due to the very broad, flat Trans-Skeleton with thin, stick-like limbs attached to it. The set came with a very simplistic "Mini-Con" Sparkplug partner kit that did have a more dedicated "Powerlinx" connector than the standard construction pegs, though these are a bit too thin to be used as attachment points for regular Mini-Cons (they stay, sort of, but it's a very loose connection). The 101-piece set also features pressure-launch missile-firing "smokestack" cannons.
1.) MP 10 EVA. Its arguably the best mold of any figure, and that color scheme! 2.) MP 12 Lambor. My fav transformer aand my fav car as a kid, cant beat it. 3.) MP Grimlock. Robot mode just looks like be dominates the shelf, regardless of who be is next to. 4.) MP Exhaust, mostly bc of the novelty factor as he is a pain to get in the States, plus his back story is cool. If not for that, MP 11 Skywarp would take this spot. 5.) MP Soundwave w/ cassettes. Duh!
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. 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.
The second known version  ditched the triplechanging gimmick on the cab and simplified things a good bit. This Powermaster Prime has several distinct characteristics only seen in the second design, such as the wider "block head" and two faux smokestacks on top of either shoulder as opposed to one. Also, in a rather odd twist, this design features a black head and fists for both super and regular modes rather than the traditional blue. It also had yellow eyes in either mode a la the original Optimus Prime.
This Optimus Prime is a redeco of the figure above, featuring red wheels and various Tech Spec-sque patterns on the legs & chest which can be decoded with their transparent red weapons, which is molded in a sprue similar to the ones used for the Arms Microns kits & Robots in Disguise (2015) Mini-Con figures. He can use any weapons included in this set, although his primary weapon is an axe.
As one of the first Transform Jr toys, this version of Optimus Prime was released under the early name for the series, Transform Gōkin. As a smaller, simplified version of the original Generation 1 Prime figure intended as a low-cost alternative for younger children, Prime features a similar transformation, with a removable head in addition to fists, but lacks rubber tires and translucent windows. As with most other Transform Jr figures, he lacked any of his major accessories, coming only with his rifle and a cardboard replacement for his trailer that had to be assembled by the buyer.
Only available at ToysЯUs, this Optimus Prime is a redeco of the Classics figure. He features a cartoon/toy accurate deco on his truck/robot parts, and vacuum-metallized upper legs & front grille to evoke his original Generation 1 toy. Like every Classics Optimus Prime mold, he still features all of his accessories. This Optimus was packaged along with the redecoed Age of Extinction Optimus Prime.
A giant-sized transforming Optimus Prime figure is set to be released for the third film. The set comes with a Leader Class-sized Optimus Prime figure and a trailer that transforms into his Omega Combat Armor - both of which combine to form Prime's Ultimate mode. This set will be released on August 1st, 2011, a month after the film's premiere.
The Hasbro release comes with a pack-in file card. In addition to the regular version, Optimus was also released in a special "advance release" assortment alongside Bulkhead, Megatron and Starscream, with each figure including a mini-DVD that contains the Transformers: Prime episode "Masters & Students". Yes, all four of them come with the same episode.
Optimus Prime can also combine with Leader-class Jetfire to form Jetpower Optimus Prime by slightly transforming his backpack and feet. Sadly, this takes away from his leg articulation, because otherwise he could never support the massive backpack he has in this mode. However, fans have created alternate configurations that increase leg articulation and movie-accuracy.
The second Nightwatch Optimus Prime was released as part of the "AllSpark Power" second half of the Movie line. He is similar to the UK version of Nightwatch Prime, replacing most of his red and blue with different shades of blue and black, retaining his resemblance to Diaclone Powered Convoy in most respects. However, the subdued black and copper on the first Nightwatch Prime have been replaced with gold and a very bright blue, to signify the All Spark energy affecting the Transformers.
Optimus Prime grew concerned when Hound picked up a communication from Laserbeak that indicated the Decepticons had grown interested in a mysterious structure near a human village. Prime and a team of Autobots headed out to investigate, and they battled the Decepticons over the structure, which turned out to be a harmless windmill. Laserbeak's Fury
His main gimmick, however, is his quintet of "Firebreath Cyclocannons"—spring-loaded dragon-headed missile launchers mounted on an ornate, rotating circular contraption attached to his back/roof. Turning the handle on top makes the backpack rotate and cycle through each cannon, and pressing the handle's button will trigger and fire whatever cannon is at the top/front. When the cannons are cycled through in robot mode, his eyes and windshield-chest light up, and one can alternatively rotate (but not fire) the cannons and activate his light-up features by pushing down on the fake spiky fenders on his stomach. Out of the package, the handle itself comes detached to allow the rest of the toy to fit.
Some time later, as the war raged between Autobots and Decepticons on Earth, Optimus had requested the Aerialbots as reinforcements from Cybertron. Though they nearly defected to the Decepticons, Optimus was able to secure the Aerialbots as allies. Later, when a power plant had to be evacuated of its human workers due to the fear of landslides, Optimus posted Denfensor at the location to secure its protection. Optimus then drove off to check up on the rest of his troops who were aiding in the area’s evacuation. Though he passed a military convoy heading towards a plant, he thought nothing of it, unaware that they were the newly created Combaticons in disguise. Optimus then reached the Ark, and from there opened communications with the Aerialbots. Optimus had someone come into the know that the Decepticons were moving in towards the plant. He watched from afar as Defensor and Superion fought Menasor and Bruticus, wary to send more Autobots into the fray while these titans wreaked havoc onto the battlefield. Optimus allowed himself a smile when the Aerialbots and the Protectobots proved themselves superior teams to the Decepticons’, though at the back of his mind, he was wary. After all, Megatron himself had chosen not to add his considerably weight to the battle... The Special Teams
Hasbro's subsidiary Milton Bradley (MB) released the toy in Europe in late 1985, following a slight delay due to licensing issues; there are no less than three variants of MB-packaged Optimus Prime, one of them manufactured by Takara and sporting blue feet, the other two manufactured by Joustra as part of a deal with Hasbro/MB, one of them with blue and the other one with red feet;
Part of the sixth wave of the 2010 Transformers toyline, this Optimus Prime is an all-new Deluxe class mold based on the original Generation 2 Laser Optimus Prime toy (see above). Transforming into a racing truck, he has some influences from the live-action movie Optimus Prime, including the more defined flames on his hood, athletic robot mode proportions and a more aggressive-looking translucent orange sword that can be held with both hands for maximum extreme chopitude. Optimus Prime features extensive use of translucent plastic in his arms, head and upper torso for a light-piping effect. Optimus also has a (non-detachable) matrix gimmick in robot mode that is formed by a relief pattern on the inside of the cab's side windows and is visible through the windshield/chest in robot mode. Like the Legends toy, he's part of "Reveal the Shield" and features a rubsign, this time on the roof. He is also very articulated and poseable, even featuring ankles and wrists that are both ball-jointed and hinged.
This version of Optimus Prime is an all new mold, being the most movie accurate so far — or at least he was until Buster Prime came out. It comes with his two energon blades, and does not have a large gap at the back of the cab like the previous Leader-class Optimus Prime. It can combine with Leader class Jetfire to form Jetpower Optimus Prime. He is also very hard to transform. The process involves unclipping his firewall from his chest in a fashion that harkens to dissecting toys that lack screws, rivets or glue. In the meantime, he keeps saying, "I am Optimus Prime," over and over due to an overly sensitive voice clip trigger. Even the most die-hard Peter Cullen fan will be sick of his voice after five minutes of playing with this toy. That aside, the quality and articulation is top-notch and the poseability is amazing. Spring-loaded panels feature in his legs as well as ratcheting ball-and-socket ankles, G1 "transforming" sound effects, and multiple "Mech Alive" features raise the bar on this figure. Of note, the fists cannot accomodate standard accessories, and on test-shots of "Power Up" mode Prime has articulated fingers, like the 2007 toy, but this feature was dropped. Also, trying to transform Optimus from robot to vehicle mode can be very difficult at first.
Rodimus can be unlocked by beating "Dam 6" in Arena Mode, credited as Hot Shot. Rodimus is described as being young, impetuous, showing enthusiasm and confidence which borders on arrogance. He boldly claims that he has both skill and looks, though he is not too keen being paired with Kup on missions. Somehow, he became corrupted by Dark Energon. If the player manages to defeat him, he calms down, shrugging off the effects of the Dark Energon and returning to his regular self.
Rodimus Prime is a fictional robot superhero character from the Transformers robot superhero franchise. He was formerly known as Hot Rod and was first seen in The Transformers: The Movie but was reformatted into Rodimus Prime when he received the Autobot Matrix of Leadership from his mentor, Optimus Prime, the leader of the Autobots, and assumed the role of the movie's protagonist. Hasbro has used the names Autobot Hot Rod, Rodimus, and Hot Shot as replacements for later characters, due to trademark issues with the name Hot Rod. His alternate mode varies between depictions, but usually possesses a red, yellow, and silver paint job.
This mold was redecoed in 2000 as Car Robots Black Convoy, and slightly retooled as his US incarnation "Scourge". After Scourge, the next use of this mold was planned to be Toxitron, which ended up being canceled. The slightly retooled version of this mold was released in 2006 in Japan as reissue Battle Convoy, which was the name of this toy during the Japanese Generation 2. The reissue used the Robots in Disguise modified tooling, with a slightly modified deco using silver vacuum-metalized plastic on his chest and trailer sides along with additional paint applications and G2 symbols. The mold was also redecoed to create a new Generation 2 version of Ultra Magnus as an E-Hobby exclusive (unusual in that the character was killed in the course of Japan's Generation One fiction).
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 line features robot versions of various Star Wars characters. Confirmed figures are Darth Vader, Luke Skywalker, Boba Fett, Commander Cody and Jango Fett. Darth Vader turns into his custom Tie Fighter while Luke Skywalker turns into an X-wing. Jango Fett and Boba Fett become Slave I, and Commander Cody turns into a Turbo Tank. There is combiner of Millennium Falcon of two characters, Han Solo and Chewbacca and Primus/Unicron-like Death Star that transforms into a giant Darth Vader. There are more Star Wars characters into Transformers like General Grievous and Obi-Wan Kenobi. This line was later revived and merged into the Transformers: Crossovers toy line, many more Transformers included characters from Star Wars: The Clone Wars like Ahsoka Tano who transforms into her Jedi starfighter, and Captain Rex who transforms into an AT-TE.
In Another Light, Rodimus finally assumes total control over the Autobots upon Optimus Prime and several of his closest loyalists being jettisoned into space and left near death following the Battle of Decepticon City. However, his reign came to a swift end when the group returned, having been reformatted into the Knights of Unicron. The heroically reborn Optimus, now known as Nova Prime, engaged his usurper in battle and defeated Rodimus, sending him plummeting into Cybertron's depths. However, Rodimus then encountered the malevolent Primus, who enlisted his aid and that of other "true Autobots" in ridding his surface of those he considered vermin-namely, all Decepticons and Autobots not loyal to the same cause. This would lead to an epic battle between Primus' minions and the heroic Transformers of their universe: Galvatron's Decepticons, Nova Prime's Autobots, and a group of Maximals created from Classics Autobots.
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). Another is based on live-action Optimus (Soundwave helmet), and the remaining one (Ironhide helmet)... actually looks to be based on the Optimus-like-but-not-Optimus Micromaster Overload! The heck?
This playset is a variation of Optimus Prime's dinosaur mode, but as a figure-8 racetrack. A launcher can propel Flip Racers through the track where they can activate a popup Chase and land in a jail. The Flip Racer MorBot is included but any Flip Racer is compatible. The raceway can be extended by attaching the Flip Racers launchers: Bumblebee’s Quick Launch Garage or Airport Blastoff Blades (sold separately).
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.
In the Cybertron universe, Cybertron was under attack by two of the Heralds of Unicron, Nemesis Prime and Ramjet. They had already damaged Alpha Trion, and while Ramjet engaged Vector Prime in a duel high above Cybertron, Nemesis Prime got past Sentinel Maximus and revealed his plan to use the Dead Matrix to drain Primus and use the energy to revive Unicron. Omega Prime, a combination of Optimus Prime and his brother, Ultra Magnus, appeared to challenge Nemesis Prime. The brothers recovered, only to receive Optimus Prime, bearing word of Vector Prime's death in battle. Prime and Magnus were subsequently seen planning the hunt for Unicron with Sentinel Maximus.
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 an almost fully vacuum-metallized Leader-class Optimus Prime in red, silver and blue (based heavily upon Generation 1 Optimus Prime), presented with a custom display base with an embossed silver Autobot insignia and a perspex display case.
We say "intended", because in actuality, the thing appears to have been produced in such huge quantities that it's wound up being made available in loads of other places—it was handed out at San Diego Comic-Con 2011, offered as a free giveaway with any order that included Transformers toys on Hasbro Toy Shop), as a free gift on the cover of the Awesome Autobots Activity Book, and came as a free gift attached to, of all things, issue #240 of the UK children's comic, Doctor Who Adventures (but not the UK's Transformers comic, you'll note!).
I agree with Aidan but would expand on his point. It’s not just that the sets seemed bigger; they were. As the relative complexity of sets has increased, so too has the piece count, but there has been an overall decline in the size of the models due to increased build complexity and a corresponding reduction in size of the pieces required to create such detail. The negative affect on perceived value in this is apparent, though I would argue, misguided when one considers the build quality and detail of new and recent sets.
TakaraTomy released another reissue based on the Encore version as part of their Chronicle line in 2011, lacking the original Generation 1 trailer. Instead, the Chronicle version was available in a two-pack with Dark of the Moon Deluxe Class Optimus Prime and a new trailer that could be used by both Optimuses, thanks to a retooled trailer hitch on the Generation 1 Optimus Prime figure.
