I mean you could argue that they are returning to the way the original Transformer toys worked. Here is an example of the OG Optimus toy. I went to Hasbro's website to see what the most current version of Optimus is that they are selling and I found this. That actually looks surprisingly similar, though I would argue they have gone more of the direction of making the robot look more robotic and the truck a little less truck like but its still a solid middle ground.

Prime soon had other things to worry about, as Magnus arrived on Earth with the intention of taking the Matrix, which he believed was rightfully his, at all costs. Prime, who refused to fight back, was seriously injured by Magnus. Magnus tracked Optimus to a desert island, where he pretended to offer him the hand of friendship, only to attempt to absorb the Matrix for himself. During the struggle, the brothers combined into the form of Omega Prime, also known as the God Fire Convoy. Through this link, Magnus was also able to channel the power of the Matrix, which he used to supercharge the Autobot Brothers into newly colored forms. Prime went on to battle the Decepticons on many other occasions. Although Magnus remained a free agent, refusing to take orders from his brother, over time, his animosity dwindled, and he frequently helped the Autobots by combining with Prime to battle the Predacons and Decepticons. During the final battle with Megatron's new form, Galvatron, the two brothers finally reconciled. Together, they faced Galvatron at the Earth's core and defeated him once and for all.

Available exclusively at the Tokyo Toy Show 2012 (along with Prime Shining Optimus Prime), Black Optimus Prime is a very minor redeco of the previously unreleased Gentei! Gentei! black version of Henkei! Henkei! Convoy, itself a redeco of the Classics Voyager Class toy. As such, Black Optimus Prime is mostly cast in black plastic, with some gray parts, translucent red windows and teal paint operations.
In this incarnation, Optimus Prime is the main protagonist and shows a near-xenophobic reluctance with interacting with other cultures, believing that such interaction would cause more harm than good. Consequently, he prohibits his team from mingling with the locals of Earth, Velocitron, and the Jungle Planet during their search for the Cyber Planet Keys. This attitude was drastically changed when Prime realized that the only way to acquire the Cyber Planet Keys from Velocitron and Animatros was to play by their laws.
The BK tie in toy of Optimus Prime is essentially two toys in one. The first part of the toy consists of two truck halves, which snap together around a sculpted robot mode Optimus Prime. The truck is squat, and primarily blue, with outbursts of chalk gray paint and red flames. Pulling back and letting go activates the gimmick: Prime "drives" forward and bursts from the truck mode, "transformed" to robot mode. This gimmick has marginal success.
The Transformers toy-line is typically divided into two main factions: the heroic Autobots and their opponents, the evil Decepticons (traditionally known in Japan as the Cybertrons and Destrons, respectively, although more recent releases often using the English terms). Transformers toys are sold at a number of price points, and various Transformers series utilize unique play features.
Part of the third wave of 2012-onwards Generations Legends Class toys, Thrilling 30 Optimus Prime is a new mold that is roughly the same size as a Cyberverse Commander Class toy. Both his truck and robot mode are based on his Don Figueroa-designed body from IDW's ongoing series, and features 5mm-compatible hands and roof. He comes with an Ion Blaster which has both 5mm and 3mm posts.
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 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.
Legion Class Optimus Prime is a redeco/retool of the first Revenge of the Fallen Legends Class figure, with the deco resembling the paint job from Optimus Prime's Western Star "5700 OP" concept truck. While the main body is identical to the figure, the arms and legs are newly tooled, with simple assemblies for the wheels. The retooled legs now features a more solid stopping point, which prevents the center front grill/legs to swing back further. It should be noted that his flame decals are painted over the side windows.
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.
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.
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.
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.
Shortly after reaching the other shore and taking out Skywarp, Prime witnessed the gigantic Bruticus bust out of the Terrordrome and attack everything around him. With Superion gone, Prime knew that there was only one way to stop this rampaging monster, and ordered his Autobots to evacuate the humans while he went looking for the Matrix of Leadership. He soon found that Snake-Eyes was in possession of the artifact, but was under attack from Megatron. Prime attacked Megatron, keeping him at bay while telling Snake-Eyes that destroying the Matrix would kill Bruticus. The ninja complied, only to learn that Optimus had left something out of the story: smashing the Matrix would kill all the Transformers, including Prime himself. Looking at the Autobot leader's body, the Joes knew that Prime had been aware of this, and had deemed it a necessary sacrifice to save the humans. The Iron Fist
The 1992 and 1993 European and Canadian releases make up what is often called "Generation 1.5", much to the annoyance of many UK fans. These toys are similar in design to the Generation 2 Transformers, having lightpipe eyes, and pastel colors. The 1993 European figures used the G2 faction symbols which Hasbro UK designed because their licence on the G1 symbols had expired. The 1993 figures were repackaged for European G2 release in 1994, and three subgroup molds got used in the US G2 line.
A redeco of the original Generation 1 Optimus Prime cab robot sporting an egregious number of Pepsi-themed paint masks and details, Pepsi Prime's differences from Pepsi Convoy are minimal: he features the shortened smokestacks previously seen on the Commemorative Series release of the mold, the blue pattern on his decals are different (matching the American Pepsi can/bottle look at the time rather than the one used in Japan), and also has a different layout for the Pepsi logo on his right shoulder. Like Pepsi Convoy, he comes with an entirely new trailer unit, specially designed to carry either a single 500ml (16.9 oz) size soft drink bottle, three 350ml cans, or 12 bottle caps (bottle cap figurines being a common and popular collectible item in Japan). In a first for the Prime mold, the figure's fists store in holes on the underside of the trailer while he is in vehicle mode. His ion blaster (which also stores under the trailer) is the first Hasbro reissue to feature the original, thick-barrel sculpt, which was reinstated to the mold by the Transformers Collection release of Prime a few years prior.
While the other Autobots searched for the Matrix on Earth, Optimus Prime searched for Vector Sigma, guided through the dangers of the planet's catacombs by the spirit of Alpha Trion. Prime eventually arrived at the computer, only to find his way barred by Cyclonus and Scourge. At that moment, Hot Rod arrived with the Matrix, the same with which Alpha Trion merged, re-energizing it. The Matrix transformed Hot Rod back into Rodimus Prime and, for the first time, the two Primes fought side-by-side and defeated Galvatron.
Power Surge Optimus Prime's scannable Autobot insignia is on his robot mode left shoulder. As he's packaged in robot mode, this badge is easily scannable while still in-package. Like his wavemate Bumblebee, this figure eventually saw release in the 11th wave of the Warrior Class line with the "Combiner Force" packaging. His scannable sticker is also altered, but scanning the badge only unlocks Energon currency, but not the character. This also applies to the original release's badge, but it unlocks 8 Ultra Sparks instead.
Back in the 60s, Hasbro was commissioned to play down the negative stigma surrounding US soldiers fighting in the Vietnam War. The result was four, 12-inch tall dress-up dolls featuring realistic camouflage fatigues and weapons of the time. The figurines represented the Army, Navy, Air Force and Marines. There was no real storyline at the time which limited the allure of the toys.

Simon Furman's "Alignment", a text story available through Transforce, a British Transformers convention, mentions Prime falling during what was intended to be the final conflict with the Decepticons at Pinea Omicron, long after the events of the Generation 2 comic book. He managed to defeat Galvatron II, but in doing so, was damaged such that Grimlock had to engage a stasis field around him to save his flickering Spark, making Prime a living war monument.
In the animated series, Optimus Prime was originally in the Autobot Academy and friends with Sentinel Prime and Elita One. When Elita is lost on a planet dominated by giant spider-like aliens, he blames himself for leaving her behind, where she supposedly dies in the explosion of a wrecked Decepticon warship loaded with Energon. Sentinel doesn't forgive him for losing her and Optimus takes full responsibly for Elita's demise. This caused Optimus Prime to wash out of the Autobot Academy. However, Ultra Magnus pulls some strings so that Optimus Prime could be captain of a strange Space Bridge repair crew composed of a war vet named Ratchet, a fledgling cadet named Bumblebee, and his fellow cadet Bulkhead. Optimus is given command of the starship which is the vehicle mode of Omega Supreme.
But around the mid-’90s, Hasbro let the trademark for a toy named “Bumblebee” lapse. At that point, the Generation 1 Transformers were almost passé, as they focused on the newfangled Beast Wars and Beast Machines lines. In fact the Unicron Trilogy continuity (mid-2000s) character called Hot Shot was originally going to be called Bumblebee, and in fact had a lot of Bee’s personality traits and yellow color, until they realized they couldn’t use the name. Fortunately, they got it back soon after.
In this incarnation, Optimus Prime is the main protagonist and shows a near-xenophobic reluctance with interacting with other cultures, believing that such interaction would cause more harm than good. Consequently, he prohibits his team from mingling with the locals of Earth, Velocitron, and the Jungle Planet during their search for the Cyber Planet Keys. This attitude was drastically changed when Prime realized that the only way to acquire the Cyber Planet Keys from Velocitron and Animatros was to play by their laws.
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.
A Voyager class figure that transforms from semi-trailer truck to robot. Head features retractable face plate. The figure's main gimmick is a spring-loaded mechanism that spins the lower torso during transformation to robot mode. Trailer detaches and transforms into a giant Ion Axe or jet pack. Prime's gun can be filled with a small amount of water. Some variants of the figure come with the Autobot symbol printed on his left shoulder while others do not.
Part of the new Adventure Shokugan series, this Optimus Prime is a transformable snap-fit kit molded in red, blue, and yellow plastic with detailing from stickers. The kit's transformation engineering is borrowed from the Warrior class figure. But unlike the said toy, the Axe must be pegged onto Prime's legs before transforming, and his shoulders are molded on his front truck halves/shoulders not being flipped down. Also, the stickers are used to cover the molded cavity on the front shoulders. As with Fixit & Underbite, Optimus Prime is fully transformable.
For some reason: unlike the stock photos (pictured from the right), This Custom Kreon had a slight QC issue to the opaque and transparent helmets: One had two sides sculpted, while the other one has the small flat square sculpt (similar to the details on Hound's helmet) on the right side. Several samples had two different "variants": One with the perfect transparent helmet & a differently-sculpted opaque helmet, while the other one has the opposite. However: later releases fixes the problem by a running change.
Revenge of the Fallen Legends class Optimus Prime is an all-new, much more accurate mold compared to the 2007 Legends class Prime, having a much greater accuracy in both robot and vehicle mode. In particular, his vehicle mode isn't inexplicably missing one smokestack like the 2007 toy. It should be noted that he was molded in only one paintable plastic color, with red and blue deco patterns decked on it. The top of the truck's bunk (ending up on his back in robot mode) has a slot to combine with Jetfire. For some reason, this isn't mentioned in the instructions, though they're hardly needed.

This figure was designed by Yūki Ōshima and produced by KT Figure Collection. The figure is actually a mini bust of Optimus Prime, which includes the head and the upper body without arms. The chest design comes with translucent blue windows and a grill on the midsection. There is also a button in the back. Pushing the button will open the chest and cause the Matrix to emerge, similar to the scene in The Transformers: The Movie.
A (technically) unreleased "black" redeco of Henkei Voyager-sized Convoy using the same plastic layout and paint mask but replacing red and blue with black, silver with gray, leaving the previously vacuum-metalized grill/fender area unpainted, changing the blue tint for the windows to red and changing all silver and yellow paint operations to blue. The red Autobot insignias would have remained unchanged.[7]
Prime is loaded with a ridiculous number of features and accessories. The robot itself is highly poseable, and both the smokestacks on Prime's shoulders and the fuel tanks on his legs can be rotated forward to act as guns, even featuring sculpted detail to this effect. As ever, he comes with a trailer that opens up into his crazy-detailed Combat Deck, featuring more action features than ever before. In trailer mode alone, it features a flip-down support stand so it can stand alone, a spring-loaded pop-out ramp instead of a fold-down one, and when the trailer is split for transformation, the traditional support legs underneath automatically swing out into place. The trailer houses most of Prime's accessories, including his ion blaster (with a moveable ammo clip to allow for multiple poses) and energon-axe, as well as his classic gas pump accessory, now with a poseable wire instead of a rubber hose. Two fold-out compartments provide storage space for six of Prime's interchangeable fists, while the other two remain attached the robot: two clenched, two open, a pointing right fist, a tilted left fist (for holding the ion blaster's ammo clip), and two fists with slots to grip the miniscule Matrix of Leadership that fits in a tiny chamber in Prime's chest. The Combat Deck's artillery robot features two flip-out handles that Prime can grip as if aiming the drone's guns, and Roller is also included, with three different 3mm ports to hold Prime's gun and gas pump. Lastly, Prime comes with a rocket pack like those used by the Autobots in such Generation 1 cartoon episodes as "Dinobot Island", and a stand shaped like the Autobot insignia that allows him to be displayed in mid-air, as if in flight. The rocket pack also has 3mm ports for Prime's weapons, and stores on the front of the trailer in vehicle mode.

GT-R Prime was racing against GT-R Saber and GT-R Maximus when they were rudely interrupted by GT-R Megatron, a ruthless racer out to prove his worth by defeating all others. A fight broke out, but Prime interrupted it and convinced Megatron that they all shared the same need for speed, persuading him to settle things with a race instead. Transformers GT: Mission GT-R

Hot Rod was then summoned to Earth by Optimus Prime, as revealed in The Transformers: Escalation. With typical bravado Hot Rod and Hardhead insisted on heading to assist Prime's unit in stopping Megatron. Hot Rod left Hardhead to assist the other Autobots while he captured the Decepticon facsimile. Unfortunately, he almost collided with Prowl, who had had the same idea. Despite some bickering between the two, they were able to eventually capture the facsimile, forcing the Russian troops to back down. When Hot Rod heard the battle between the Ore-13 powered Megatron and the rest of Prime's troops, Prowl forbade him from interfering, entrusting him with the safe return of the facsimile. Calling Nightbeat for transport out, he was jumped and severely damaged by Skywarp and Thundercracker. Nightbeat teleported him away, but Hot Rod had been badly damaged, and the facsimile reportedly killed.
This release of the Japanese Super Ginrai version of the of Powermaster Optimus Prime was a Toys R Us Japan exclusive black repaint, made to represent the original Convoy/Optimus Prime equipped for a special mission. All of his red and blue plastics were changed to black, his clear blue windows were now tinted red, making his overall colour scheme very reminiscent of the now-familiar 'Black Convoy' colour schemes.
A non-transforming model kit of Optimus Prime by Takara Tomy, sold exclusively in Japan. The kit comes with a pre-assembled inner frame that features a high rate of poseability similar to Master Grade Gundam model kits. The kit comes with two swords and two different sets of attachments for them: one set for the forearms and the other to replace the hands. Pre-ordered units of the first batch came with battle hooks.[138]
This series introduced the dangerous Predacon faction, robotic dragons and mythical creatures that posed a threat to Autobot and Decepticon alike. In response, the 'Bots and 'Cons don new armor (the Autobots in spiky, over-weaponized armor reminiscent of Mad Max, while the Decepticons take on more beastly traits) and are armed with new gimmick-laden launching/spinning weapons. On-package bios were reduced in length to just a sentence or two, and the instruction sheets instead feature facts about one of the figure's main weapons, as well as a chapter of the Tales of the Beast Hunters prose story.
The second known version [4] 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.

Available in the Timelines "Generation 2" 2-pack alongside Sgt. Hound at BotCon 2015, General Optimus Prime is a redeco of Generations Voyager Class Roadbuster based on the cancelled Generation 2 General Optimus Prime toy. He transforms into an off-road vehicle and comes with numerous weapons, all of which peg via 5mm post onto his vehicle rear/legs, shoulders, upper & lower arms, and hands: a spring-loaded, missile-firing launcher, a pistol, a rifle, and two small cannons that respectively form the scope and stock of the rifle. All of his weapons can combine to form an unwieldy superweapon. It was unknown if this figure has the loose ratcheted shoulder joints from the Legends release of the mold.

The cab transforms into the robot mode of Optimus Prime himself, with the addition of a pair of removable blue fists that plug into his headlights. The fists themselves do not store anywhere in vehicle mode, but can fit easily in Prime's opening chest compartment (originally designed to accommodate two Diaclone driver figures). Prime is armed with a black laser rifle that, due to design, he cannot hold straight.
