Naturally, Optimus Prime got the biggest of the sets in the first year of Kre-O. The set can be built into a large long-nose tractor-trailer rig with a removable "sleeper" cab that hides a computer station, and a trailer that can carry the set's two motorcycles or open up to carry larger car builds. The robot mode build includes a huge Optimus, based largely on the live-action movie Optimus, though with a head based almost directly on the Classics Voyager Optimus. He is armed with a distressingly plain brick that fires pressure-launched missiles (aka his smokestacks). Most of the leftover parts in robot mode become a "headquarters" which is mostly just a random assemblage of mismatched-color panels and a pair of barricades. Both main builds leave numerous parts unused if you go expressly by the instructions, but hey, it's a building kit, surely you can find someplace to apply most of them.
Activision and Traveller's Tales, creators of the Lego Star Wars games, released Transformers: The Game in 2007, accompanied by Transformers Autobots and Transformers Decepticons, to tie in with the live-action feature film for the Sony PlayStation 3, Microsoft Xbox 360, Nintendo Wii, Nintendo DS, PC, Sony PlayStation Portable, and PlayStation 2. The player was able to play as both the Autobots and the Decepticons, pick up and throw objects, and transform at any time. The steering in vehicle mode was compared to that of the Grand Theft Auto games and had a free-roaming environment.
The figure would have come in a monochrome version of the standard Henkei! Henkei! Convoy's packaging, still named "Convoy" but now labeled as part of the Gentei! Gentei range of exclusives. Reportedly, this figure was intended as a Wonderfest exclusive, but was canceled because, according too TakaraTomy designer Shogo Hasui, it was too similar to Universe Nemesis Prime. Knockoffs were later made available, so buyers beware!
Another redeco of Deluxe-Class Dark of the Moon Prime, this release uses a darker grey, a less magenta-y red, and less gold on the front end. Included is the trailer originally available with the Chronicle release. The trailer holds up to seven MechTech or similar 5mm peg accessories. Four holes are located on the top-front end of the trailer, with another three inside. The door also folds down to become a ramp, and the inside of the trailer is big enough for several Legion or Commander Cyberverse toys, or one smaller-end Deluxe figure. Two C joint bars also run along the bottom of both sides.
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.
The toy's primary gimmick is its auto-transforming trailer, which assumes one of three configurations when triggered by an infra-red signal transmitted from the cab robot. Transforming the cab into robot mode will cause the trailer to automatically flip open into a battle station for Mini-Cons, which Prime can stand in the centre of. The base features a central tower with a pop-out artillery emplacement and a mount for Prime's large cannon; a rotating missile-firing turret; two Mini-Con storage bays, one of which featured a manually-activated tab to launch Mini-Cons out; and two live Mini-Con hardpoints, one of which pops up a non-firing turret, the other activating a laser noise.
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.
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.
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
But it is scary to think that there is a strong possibility they will look at redoing almost every Masterpiece now if this is a success. The MP+ releases have me feeling tired. I don’t have to get them but I have a completionist mentality. But a redo... I’m almost ready to check out of MP completely. I waited so long to get six seekers done pretty well to me. Now there’s a chance they will redo them. And soundwave. I sure hope I’m just being a worry wart.
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.
Great read. I have noticed an absolute drop in quality myself. My sets in my youth range from 83 to 90. My sons are from 2011 and there is a clear distinction. Aside from the weight of identical bricks being different, the older bricks stay together in a much more durable way than the new bricks. To test this, I created the same models using all old bricks and all new bricks and the difference was marked. I understand doing certain things to reduce costs, but not at the expense of quality…
After their own Optimus Prime disappeared, Scavenger and Smokescreen discovered an alternate version of Optimus Prime lying unconscious and barely alive in Autobase Earth. Though Red Alert did what he could, the mysterious Prime reactivated only long enough to utter a cryptic statement about the walls crumbling and the coming of chaos, then died.

A redeco of Deluxe Earth Mode Optimus Prime with the jet pack attachments and a smaller version of Ultra Magnus' Mass Hammer, as seen in the "Endgame" series finale. The Wingblade attachments are also compatible with Voyager Optimus Prime. The figure never saw a release in the U.S. market due to Hasbro's decision to cancel the toy line, but a variation of it was made available in Japan.
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.
