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.
If Optimus destroyed the duplicate Cosmos, the real one would inform the Autobots of the Decepticons’ schemes, and the convoy would roll out to take on their adversaries. They were soon met by a squad of flying Decepticons, but were at a strict disadvantage against their adversaries as their vehicle modes possessed no weapons. The Autobots nonetheless managed to fight their way to the Decepticons’ base, one way or another, and defeated the Decepticons by using their own gravity weapon against them. Desert Flight
In Transformers: Armada and Transformers: Energon, Optimus Prime shares the role of main protagonist with Rad, Alexis, Carlos, Starscream and Hot Shot. The Optimus of this universe shares many similarities with his parallel universe versions, including nobility of spirit and a strong desire to protect all humans on Earth. In this continuity, the two sides are not looking for energon, but a small race of power-enhancing Transformers known as Mini-Cons. Optimus led his small band of Autobots to stop Megatron from acquiring their power for himself.
The second War Within Optimus Prime toy in the Titanium series, but also the first official transforming toy from the War Within series. Personally designed by comic artist Don Figueroa (who created much of the War Within comic designs), Optimus Prime transforms into a Cybertronic truck. He is armed with a silver painted Ion blaster, on which the word "DON" can be clearly seen sculpted into the body.
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.
A BotCon 2012 exclusive purple redeco of the Deluxe "Generation 2" Optimus Prime figure from the Generations toy line, with the sword's blade molded in clear yellow. Much like the 2008 Voyager figure, this figure has painted-in "battle damage" effects. The right side of the hood has the words, "I shall stand...", while the left side says, "The rest shall fall."
General Hawk stated in an interview that his typical transportation in Axiom Nexus was his Convoy colleagues. As the seats of General Optimus Prime's vehicle mode were manufactured at the same location as the VAMPs of his universe, Hawk was able to find a degree of familiarity in the strange world of Axiom Nexus.

JETWING OPTIMUS PRIME Black Ver. is a black, teal, and chrome redeco of Jetwing Optimus Prime exclusive to the Asian market. He appears to have been based on the cancelled TakaraTomy contest prize Jetwing Optimus Prime Black Version (see above), with a few color alterations here and there, plus the obvious addition of chrome. It was originally solicited by online retailers as the far goofier-sounding "Dark Nightwatch Jetwing Optimus Prime".
Toymaker Fischer Price was the knight in shining armor on this one with the creation of their Power Wheels line. At first, Power Wheels vehicles were very basic with small electric motors and rudimentary Jeep-like styling. Now, Fischer Price has unleashed a car that says "When I grow up, I want to be too rich to care about the environment." This giant bastard comes with tinted windows, a set of dubs and even a fully functional FM transmitter which, no doubt, blasts shitty radio static through its real-live rear subwoofers.
When the long-lost Titan Masters reemerged into modern society and joined the Autobot-Decepticon war, Optimus Prime was partnered with the Titan Master Apex, who carried a portion of Prime's spark, boosting the legendary commander's already formidable abilities. Titans Return Apex/Powermaster Optimus Prime toy bio On Velocitron, Optimus Prime was present for the biggest race of the year when Scourge and Crashbash arrived and attempted to botnap Hyperfire. Optimus ordered Sentinel Prime and Hardhead to battle against them. Later, Optimus was part of a battle on Cybertron against Soundwave. During the battle, the Autobots' base Fortress Maximus transformed to thwart the Decepticon advance. Optimus Prime declared that to defeat the Decepticons, the Autobots would need to master the power of the Titan Masters. Titans Return: The Power of the Titan Masters
Generation 2 Optimus Prime comes with all his original accessories, as well as two major new play features. To increase his arsenal, he is armed with a pair of black missile launchers that fit in his fists and fire red spring-loaded missiles; these launchers were retooled from the G.I. Joe figure Barricade. Secondly, he comes with an electronic "sound and lights module" that can either plug into the front of the trailer (where it resembles the air conditioners used on refrigerated trailers), or hook onto Optimus's back in robot mode (via a new slot sculpted into the cab robot). Unfortunately, the soundbox is heavy enough that doing so can easily overpower Prime's hip joints, causing him to topple backward. The soundbox features a large, vacuum metalized Autobot symbol on its front, and three grey buttons which trigger two flashing red LEDs on either side of the module, and a trio of sound effects: a truck engine noise, a laser gun sound effect and a garbled voice that said "I am Optimus Prime!". The module also features ports on either side into which the missile launchers can peg.
With Season One of Cyberverse drawn to a close, we have word of a newly-listed Cyberverse DVD currently available for pre-order. Titled ‘Transformers Cyberverse: The Journey’, the anthology consists of 66 minutes of product, which can only be assumed to consist of the first six episodes, given the DVD’s plot synopsis and the title of the collection corresponding to the show’s fourth episode, ‘The Journey’. The DVD itself is listed here by New Zealand based online retailer - Read More
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.
Not depicted in the instructions or stock photos, Roller can attach to Prime in vehicle mode via two tabs on the vehicle front which slot into two corresponding slots on Prime's feet. Another undocumented feature is that the butt of the Ion Blaster can be inserted between the barrels of Roller's weapon mode to form a longer weapon. Also not shown in the instructions but depicted on the stock photo on the card-back is that Prime's shoulderpads can be rotated up; the intended positioning for this is notched, although you can position them at other angles.
In light of this news, if Optimus decided to nonetheless head back directly to Autobot headquarters, his squad returned to find their comrades nearly dead from the poison. But with Ratchet’s help, the antidote was quickly distributed, and the Autobots sprung back to life. Now cured, the Autobots discussed their next course of action; they had to prevent the Decepticons from poisoning the nearby water reservoir.
I wish I could FIND more of the toys - for some reason my area is a toy desert and it seems to be hard to find good TFs. Of the ones I've been able to find, my favorites are all CHUGs, because I end up wanting to get things that look closest to G1. (Sorry. I'm old, poor, and sentimental.) I have more luck at thrift stores than I do at mainstream stores, so I have a ragtag fleet of oddballs with missing parts/untranformables locked into robot mode, etc.
Part of the sixth wave of Custom Kreons, and the first (and only) Robots in Disguise-themed wave, Optimus Prime uses the new 2015 Kreon construction with the hollow waist-peg and "raised" hands.. He comes with a buildable parts rack on which to hang/store his extra pieces. Unlike the previous Custom Kreons, he no longer features a chromed helmet, and comes with an extra clear-plastic helmet, torso, legs, and his arms, plus a chromed Bazooka (originally from the Kre-O Battleship sets), and some kind of a dual pick-axe with a clear red staff.
The TakaraTomy version, part of the first wave of Movie Advanced Series toys, is dubbed "Classic Optimus Prime", and opts for a deco closer to Prime's previous on-screen appearances, omitting the blue paint on his feet and hands to reveal the gray plastic underneath, and adding new paint details all over. Instead of painting it in clear light blue, his light-piping eyes is neutered with opaque light blue paint. In terms of quality control, at least one sample has missing it's silver paint on the head's left cheek.
Optimus Prime has a wide range of articulation for a relatively bulky figure. He has ratcheting joints in his shoulders, elbows, hips and knees, with swivel joints and ball joints supporting them in his biceps, lower knee joints and ankles. Again, unusually for a mainline figure, especially at the Leader pricepoint, his hands have individually articulated fingers and thumbs, but no wrists.
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.
In Transformers: The Last Knight, he is brother-in-arms with Bumblebee who he fought alongside with to foil the Nazi Party in World War 2. He speaks with a thick French accent due to being stuck in France for so long, much to his own embarrassment. He wields a special gun which can briefly slow down time. He is also the only Transformer who is shown to speak in vehicle mode. 
Apparently, early plans for the shield were to have it colored gold and silver, but it was later changed to gray and red. When a hand-painted prototype of the toy was first displayed at the 2013 New York Comic Con, the shield was colored yellow and silver; in addition, the original versions of the official Hasbro stock photos also depict the gold color, but the versions featured on the back of the toy's packaging were edited so they would accurately depict the final toy's colors for the shield. Meanwhile, the versions of the stock photos provided to websites and online retailers depict the shield in its final colors for the robot mode, whereas the vehicle mode photo is the unedited version featuring the shield's original colors. Furthermore, UK-based retailer Argos also featured unedited versions of the stock photos for both modes in one of its catalogs, causing some confusion among fans. Sometimes, the spring loaded "Automorph" feature in his head is too strong and causes the head to fly off...
Smallest Transforming Prime was redecoed the following year for the second wave of the line, into a color scheme based on his Generation 1 cartoon appearance featuring brighter reds and blues, white thighs, yellow details on his bumper, and blue eyes and windows. This version of the figure was made available for a second time in the next wave ("Wave 2.5"), with a new anime-decorated version of the Combat Deck now available as a rare "chase" figure.
Though the figure does a much better job of conveying the on-screen character model than the ROTF Leader Class mold did, there are still a few inaccuracies—most notably the forearm and shoulder pad designs and the head/torso proportions. The final product also lacks certain paint details visible in stock and packaging imagery, such as the blue rings on his feet and the gold on his pelvis. It should be noted that this mold does not combine with Jetfire.
In the Japanese exclusive Transformers: The Headmasters storyline (which replaced the "Rebirth" finale in Japanese continuity), Hot Rod appeared as part of Optimus Prime's inner circle. When Galvatron and his Headmaster warriors launched a devastating attack on Cybertron, Vector Sigma was damaged, and Hot Rod was sent to Earth to retrieve the Matrix. Recovering it, he returned it to Prime, only to be surprised when the ghost of Alpha Trion once again reformatted him into Rodimus Prime to help Optimus. After Prime's second death, Rodimus once again took command of the Autobots. However, when Scorponok destroyed Vector Sigma, Rodimus decided to leave the war, and left Fortress Maximus in command of the Autobots.
Kiss Players Convoy is a redeco of Alternators Optimus Prime. While the figures may appear similar at first glance, given that Kiss Players Prime is still red, blue and black, there are many subtle differences, not least of all the replacement of the Alternators figure's bare, flat red plastic with a deep metallic red paint. Several of his body parts are cast in different colors of plastic (for example, his shins, formerly black, are now blue, while his formerly-blue hands are now black), and he features more intricate paint applications on his shoulders, and especially his pelvis, which is decorated to look like Prime's traditional bumper.
This highly accurate model kit of Optimus Prime is a Japanese exclusive. It is extremely possible, and comes with his two swords that can be mounted either on his fore-arm, or the hand can be removed and it placed in the wrist via ball joint. His appearance is based on his Dark of the Moon look, as it his "Abbs". The head can be made either with the face-plate on or the face-plate of which reveals a detailed face. Interestingly though, he doesn't come with any of the guns he uses in the films, though it is thought he can hold Buster Prime's gun.
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.

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.
