Optimus Prime is primarily voiced by Peter Cullen in most of his incarnations, who voiced him in the original series. Following the production of the 2007 film, Cullen reprised his role for the sequels and supporting media and would even voice Optimus in later series such as Transformers: Prime. Optimus has been voiced by a number of other voice actors in other series such as Neil Kaplan, Garry Chalk, and David Kaye in the series Transformers: Robots in Disguise, Unicron Trilogy, and Transformers Animated, respectively.
Somewhere along the line, G.I. Joe picked up the familiar storyline that we all best associate with the toys: G.I. Joe Team vs. the Evil Cobra Organization. A classic tale of good vs. evil. Well guess what. Somewhere else along the line the franchise picked up a very different storyline and a new look to boot, highlighted by the newest figurine: The DARK NINJA MASTER.
Transformers GT "GT-R Prime" is a heavy retool of Alternity Convoy, transforming into a 1:32 replica of the Motul Autech GT-R race car used by the Nismo team in the Super GT racing championship series. He retains the flip-out blasters of the Alternity toy and can also wield his new Impact Wrench Gun accessory (also called the "Optimus Rifle" on the Transformers GT website), a weapon based on the impact wrenches used in car repairs. Like all GT toys, Prime also comes with a GT Sister, poseable human figures themed after race queens, his partner being a lady named Misaki.
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. 
On a version of Cybertron where Energon shortages have left many of the surviving Autobots and Decepticons all-but immobile, Hot Rod opted to be converted into a smaller and more efficient Micromaster, and thus retained his mobility. Detesting the corrupt system that has fallen into place, Hot Rod seeks to reform Cybertronian society from within the established government, while his former comrade Grimlock joined the resistance in an effort to bring down the old order. Feeling this approach to be no better than Megatron's rebellion that triggered the Great War, Hot Rod opposed Grimlock's efforts, particularly when his plans came to include using the G-Virus to turn a large number of "Builders" into immobile clones of Galvatron, unaware that the effects would also spread to a number of Maximals, Predacons, and Micromasters. Fortunately, Grimlock was betrayed by one of his own men, who destroyed most of the virus, though not before one Cybertronian was infected.
One reason that people perceive that the cost of Lego has gone up is that the cost of so many other toys has gone down. You can now buy so much crap for a buck or two that Lego seems like a luxury item in comparison. It’s interesting to look in toy catalogs from the early eighties and see that Lego didn’t seem as costly then because the other toys were all costly as well.
Optimus was challenged to a duel by Megatron as a distraction while the Constructicons attempted to strike against Teletraan I. Heavy Metal War - Part 1 Concerned that the Decepticons might try to steal a new Energon related technology from a science facility, Optimus sent Blaster to infiltrate and protect the base. Espionage Optimus was impressed with Grapple and Hoist's plans for a Solar Power Tower, but thought it would be too difficult to defend from the Decepticons. The Master Builders Following the return of the Aerialbots from a trip to Cybertron, they told Optimus and Elita One about how they'd encountered Orion Pax and Ariel. Golden Age Optimus was among the Autobots affected after Megatron sabotaged their recharging chamber. Turned evil, Optimus was sent to attack Rutter Military Base and obtain a solar power satellite. He and the other Autobots were returned to normal by Sparkplug's attitude exchanger, and Optimus promised to repair the base. Attack of the Autobots
He made it out of the building and ran into the real Sunstreaker, who blasted the 2 clones following Hot Rod. Sunstreaker ignored Hot Rod's warning about Scorponok's army and stormed into the building so Hot Rod painfully wired himself to send a distress signal. When Sunstreaker's real head was later disabled by Hunter, the Headmaster clones shut down, which Hot Rod explained to Grimlock. The group was surprised by the arrival of Shockwave, but Ultra Magnus had heard Hot Rod's distress call and was on his way to Earth. After Scorponok knocked out Sludge and Grimlock tended to him, the remaining Dynobots offered Hot Rod a lift aboard the Monsterbots' ship. He refused though, and made it back into Machination HQ to take care of something "personal". He eventually found Scorponok's real head. Hunter also showed up and let Hot Rod know how to disable it, but before he could do so, Scorponok grabbed him. Before Scorponok could crush Hot Rod's head, the Dynobots showed up and began to battle Scorponok. Hot Rod told Swoop which wires to sever, and he did just that, reducing Scorponok to a catatonic state. Ultra Magnus arrived took everyone back aboard his ship, which later docked with the Ark-32. Within 3 days, Hot Rod was fully repaired, with a new body form design.
In the final episode of Transformers: Cybertron, Optimus Prime proposed a new Space Bridge project using the power of the four Cyber Planet Keys and the four great Cybertronian ships. Many Autobots and former Decepticons joined in the project. Jetfire was left in charge of Cybertron as Optimus Prime led the Atlantis with the Earth Cyber Planet Key, joined by Red Alert, Safeguard, Scattorshot, Leobreaker, Menasor, and Heavy Load.
The stickers may not be cut right, my copy has them off-center, they're probably using an 80's type bladed stamp with little QC to rush them out. The cab will not have the stripes applied, those are included on a strip of mylar/foil/whatever silver but you have to measure and cut them to fit. Every KO can be identified easily by these missing stickers in the box. Older releases also had the trailer's stickers separate but those have not been made in some time.
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.
How to Say Expensive and Mean It - The Seibertron.com Twincast / Podcast reaches episode #213, and the discussion begins with Takara Tomy's upcoming Masterpiece MP-44 Optimus Prime version 3.

The Jetwing jet pack attaches onto Optimus Prime via a part that hooks onto one of the hinges behind his neck, and a spring-loaded clamp that latches onto a recessed area under Optimus' back. The fuel tanks that form Optimus' Ion Blaster must be removed for this mode, and they can be stored inside the engines for the jet pack. The Jetwing can be used on previous Leader Optimus Primes from Revenge of the Fallen onwards, but due to the lack modifications seen in Jetwing Optimus Prime, the combination isn't as stable. The jet pack features four MechTech ports on the main wing articulation points, and two C joint mounting points on each wing. The Gatling Cannons both feature two MechTech ports and 2 C joint mounts on either side of each cannon.
Outstanding work here. After reading a number of complaints about how the price has ‘increased’ over the years, it’s great to see this analytical approach. One additional hypothesis I have is related to the increase in the number of sets released each year, which would appear to be supported by your data. More sets to buy to be ‘complete’ makes for more money out of pocket.
Legends class Optimus Prime is an extremely simplified toy of the extremely complex movie design. As such, he features numerous unavoidable inaccuracies, such as not transforming or even looking very much like the original design or the larger toy versions in robot mode. However, proportionally Legends class Optimus Prime is not far off from the real truck and the Leader class toy's vehicle mode, aside from missing a smokestack on the driver's side. He is articulated at the shoulders and upper legs via ball joints. He can also hold small weapons, such as Cyberverse.
The designs for the original 28 figures were made by Kojin Ono, Takashi Matsuda, Hideaki Yoke, Hiroyuki Obara, and Satoshi Koizumi. Hasbro would go on to buy the entire toy line from Takara, giving them sole ownership of the Transformers toy-line, branding rights, and copyrights, while in exchange, Takara was given the rights to produce the toys and the rights to distribute them in the Japanese market.
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.
Part of the first wave of TakaraTomy Go! toys, Hunter Optimus Prime is a redeco of the Voyager Class Beast Hunters Optimus Prime toy. His red and blue plastics are now cast in metallic shades, his translucent green plastic has been replaced with translucent blue, his yellow highlights are more orange-yellow, his yellow-painted side windows are now blue, and his gray plastic is now cast in two different, darker shades. The Matrix Saber, aside from being blue, uses a bluer shade of gunmetal paint for its hilt and handle.
Optimus and his Autobots were aboard the Ark, on the run from the Decepticons. With him, Optimus had what Megatron was forever seeking; the AllSpark! With the ship taking heavy damage from the Autobots' pursuers, Optimus ordered Jazz to take them into an emergency quantum jump. Jazz informed Prime that the jump would take longer to initiate than the time the Decepticons would need to board their vessel. As such, Optimus entrusted the AllSpark to Bumblebee while he and the rest of the bridge crew steeled themselves to hold off their enemies. Thanks to Starscream breaking rank in the Decepticons' formation, Optimus was able to hold back Megatron, and with Heatwave's help, repel them from the ship just as it initiated the quantum jump. However, at that moment the AllSpark tumbled off-ship, falling into the quantum tunnel and seemingly being lost for good... Angry Birds Transformers #1
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.
The series begins when Optimus and his crew, after picking up a disillusioned ninja named Prowl, are sent to clear rubble from a space bridge passage. There, the Autobots stumbled upon the Allspark and are immediately attacked by Megatron's battle cruiser, the Nemesis. Through treachery by Megatron's second-in-command, Starscream, Megatron was fragged and the Autobots crashed on Earth in the early 21st century. After being in stasis under Lake Erie for 50 years, the Autobots awaken in Detroit of the near future, where they immediately discovered humans in need and became heroes of the city after stopping a Sumdac Industries experiment gone wrong. During the battle for the possession of the Allspark, Optimus goes offline after defeating Starscream, only to be revived by Sari Sumdac and her Allspark-infused key.
Hot Rod then fought in the battle of Autobot City and saved the city for if he had not attacked Megatron, he would have destroyed it. Due to his attempted intervention in the epic battle between the Autobot leader, Optimus Prime and the Decepticon leader, Megatron, Prime was lethally injured. Before he died, the Matrix got passed on to the Autobot Ultra Magnus, whom he referred to as "old friend", despite protestations.
In robot mode he resembles previous Optimus characters: his angular chest windows are reminiscent of Cybertron Optimus Prime, while his near-animalistic limbs and color scheme are evocative of Beast Wars Optimus Primal. He has excellent articulation due to his many ball joints, and is armed with a rifle. The flame attachment can fit onto the end of the (non-firing) gun barrel.
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.
In Transformers: Armada, 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.
In "Reunification", Optimus is seen building his new ultimate weapon, Omega Doom. He learns that Megatron has supposedly been killed by watching a broadcast from the Autobot reporter Rook. When Kup leads the Autobots Camshaft, Hound, and Warpath, in an attempt to assassinate Optimus Prime, the Autobot leader easily defeats the four rebels. Alpha Trion then attempts to kill Optimus, but Optimus uses Omega Doom against the ancient robot. Prime then sends Doom against the Decepticons.
Of particular note to Prime completists is that this otherwise traditional reissue of the Generation One Prime cab has a brand-new head sculpt which is essentially a miniaturisation of the Masterpiece/20th Anniversary Prime's noggin. Not only does this give the "classic" Prime toy a more show-accurate head, it's also the first iteration of this familiar mould in which the head is actually poseable. Being one of the better-articulated early Generation One toys, Prime can finally look in any direction he can aim.
