The "Underbite Jetpack Takedown" Optimus Kreon uses the new 2015 style of Kreon hips and torso, with a hollow hip-peg and a central post inside the torso for increased grip... which also makes them incompatible with about four years' worth of Kreons. Based on his appearance in Robots in Disguise, he features a new version of the Optimus helmet, this time lacking a moutplate. He attaches to an included jet pack, armed with two pressure-launch missiles.
As had first been done in the Armada line, Takara elected to supplement their release of the Super class Optimus Prime figure with a new-mold Deluxe class toy. Coming without trailer, Prime Force or electronics, this Prime discarded the larger toy's ability to form Super Mode in favor of being able to Powerlinx with the other compatible toys of the Energon line, forming either a torso or a pair of legs that the other Autobots could connect to. Like the Deluxe Armada Prime, this one too was on the small side for its size class, but just as that figure could, this small Prime can still tow the Super class figure's trailer.

Like the original figure, Powermaster Prime is composed of two major components: his truck cab, which transforms into Prime himself, and his trailer, which is essentially a heavily-armed version of the original. The trailer has a fold-down ramp to allow the storage of a smaller Transformer, or perhaps spare accessories. The trailer transforms into a battle station armed with two long black rifles and two grey double-barreled cannons (featuring seating for Powermaster engine figures), all of which Optimus Prime can also wield in his fists.


The first in TakaraTomy's Hybrid Style series, Galaxy Convoy is a partly die-cast figure with scaled-down equivalents of the accessories that came with the Leader-class figure. This highly-intricate figure retains all the transformation abilities of the original figure—vehicle, flight mode, robot, and Super Mode—and even its Cyber Key-activated features (even coming with two keys so they can be deployed simultaneously), with additional touches like spring-loaded mechanisms that snap his cannons into place, and hand-grips on the weapons for Super Mode. While he does lack electronics or firing missiles, Prime still includes his Matrix, super-tiny yet still removable, and has four alternate sets of hands: two clenched fists, two with pointing index fingers, two with splayed palms, and two curved hands for holding his various weapon handles. Given the figure's small size, a reconfigurable head was infeasible, so it also comes with an alternate Super Mode head with a mouthplate and crests deployed, though the standard head must be attached in order for the figure to be transformed to vehicle mode.
Following the awakening of the Transformers on Earth, the Autobots protected the planet from the Decepticons. Over the next fifteen years, the Autobots befriended the humans, particularly the Witwicky family. The Autobots finally allied with humankind and eventually defeated the Decepticons at the turn of the century. They planned to return to Cybertron aboard the newly constructed Ark II, along with seven humans, including Witwicky patriarch Sparkplug. Prime Directive #1 Before the ship departed, Prime gave a piece of the Matrix to Spike Witwicky, Sparkplug's son and Bumblebee's closest human friend. Prime Directive #2 But the ship was destroyed as part of a military conspiracy to take control of the Transformers.
The Autobots United 5 Pack includes another redeco of Voyager Class Evasion Mode Optimus Prime. This release features the faceplated headsculpt and, unlike the rest of the set, which strives for screen-accuracy, features a heavily Generation 1-inspired deco. Deco changes include replacing most of the blue & grey plastic into red, with blue paint applied on it, and his dark grey plastic is now a lighter shade. His Ion Cannon is now painted black to resemble his Generation 1 toy's blaster, color-wise.
EZ Collection Gum Convoy is another redeco of Generations Legends Class Motorbreath, featuring the retooled parts, but this time omitting the sword. He is decoed once again in his Generation 2 colors (see above), with the black legs, but uses metallic red plastic, and is coated in metallic red, blue, and black paint. As per the toyline's name, he comes with a yellow candy-shelled piece of lemony-flavored gum.
Megatron came upon Optimus and challenged his old foe to a duel. Optimus managed to gain the upper hand, but hesitated to deliver the killing blow when he discovered that Megatron had married the Matrix to his spark, corrupting it. Several Decepticons then swarmed Optimus, allowing Megatron to blast a hole through his chest. Dead and defeated, Optimus plummeted down into the bowels of Cybertron. Pax Megatronus Rodimus and Duke travelled far beneath Cybertron, where they discovered Ultra Magnus- the Autobot god of death -carrying Optimus's body away. Earth: R.I.P.
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.
Like the original Warrior Class Optimus Prime, the figure features an undocumented feature: His axe can be stored on his vehicle mode trailer. Additional features include storing the axe onto either of his leg hooks, combining the launcher with either of the swords at their hilt, and storing the launcher underneath the vehicle. In a neat bit of engineering, he can fully transform with his swords attached.
Late in 2008, this version of Optimus prime was one of four Classics figures repainted into HasbroToyShop.com exclusives (the other three being the Megatron from this set in G1 colors, Grimlock repainted into Overkill, and Mirage repainted into Dragstrip). Unlike those three, it's debatable just how much repainting went into Optimus, but he comes in a snazzy new box.
The Masterpiece Optimus Prime toy was featured in a print ad for Nokia 6820 phones in December 2004.[19] He is posed bent over to look at the phone and scratching his head. Pleasantly, most of the pose pictured is perfectly possible with an un-kitbashed, un-Photoshopped version of the toy. (The real toy can't bend forward at the waist like that, alas.)
In lieu of combining with the Prime Force, Optimus Prime can also merge with Energon Wing Saber in a similar fashion, with Wing Saber splitting into four components that connect to Prime as limbs. Wing Saber's red and white torso components can become arms for Prime while his legs attach to Prime's own, creating Prime's "Flight Mode", but the parts can also be swapped around, with Wing Saber's legs deploying large missile launchers and becoming arms to make Prime's "Fight Mode". Alternately, Prime can combine with Energon Omega Supreme to form what his packaging calls "Powerlinx Omega Supreme", but which the cartoon named "Optimus Supreme". The Prime Force drones can attach to four connectors on Optimus Supreme's body.

Megatron came upon Optimus and challenged his old foe to a duel. Optimus managed to gain the upper hand, but hesitated to deliver the killing blow when he discovered that Megatron had married the Matrix to his spark, corrupting it. Several Decepticons then swarmed Optimus, allowing Megatron to blast a hole through his chest. Dead and defeated, Optimus plummeted down into the bowels of Cybertron.

Optimus was one of the many soldiers fighting under the command of the Autobot leader, Jetfire. He was among the Autobots who launched in the Ark to clear a path through an asteroid belt. When the Decepticons attacked the ship, he fought a Seeker Decepticon while Jetfire sent the Ark crashing into Earth, knocking everyone aboard offline. Four million years later, they were repaired when the ship's systems were reactivated by a volcanic eruption. In the Transformers
Epic Optimus Prime is a 22 inches tall, non-transforming Optimus Prime figure, featuring limited articulation in the waist, shoulders and wrists. His chest can be opened to reveal a command center with a seat and room to display at least three figures. His arms also feature one seat each to accommodate more figurines. The back of his arms and legs are hollow with "shelves" that allow even more figurines to be displayed.

Available only via mail-order through Dengeki Hobby magazine, the "Limited Black Version" of G1 Convoy is just that: a straight black repaint of the G1 Convoy toy. He comes with all his original accessories, appropriately redecoed (including a silver version of his axe), as well as a gold-chromed version of the "Calamity Defenser" Solitarium weapon that came with Psycho-Orb.
The sequel series, Transformers: Robots in Disguise sees Optimus contacting Bumblebee to warn him of danger on Earth-a prison ship's complement of Decepticon prisoners escaping upon the ship crashing and appearing briefly in physical form to help Bumblebee's unlikely new team defeat the Decepticon Underbite. Optimus appears throughout the first season as a vision to Bumblebee, though he is only allowed to do so when the latter's need is dire. Residing in the "Realm of the Primes", Optimus Prime begins training to combat an "ultimate evil" where his first part of the training is overseen by Micronus Prime. At the conclusion of the first season, Optimus is upgraded by the Thirteen Primes when the Fallen arrives on Earth, during which he gains a body that closely resembles his Beast Hunters form. After the Fallen is seemingly destroyed, Optimus Prime remains with Bumblebee's group, though he states he would only do so as Bumblebee's "equal", rather than leader. However, the Thirteen subsequently reclaim the additional power they granted him, leaving him weakened but still determined to aid the team.

The figure has useful swivel joints at the shoulders and neck, and not-so-useful ones at the wrists and knees. It comes fully painted and pre-assembled, but true to his garage figure origins his Ion blaster must be cut free using a hobby knife, then assembled. His clear blue chest window piece is removable to allow the installation of his Matrix of Leadership, as is a Movie-style Matrix cover (not pictured). He also comes with an alternate hand that allow him to hold his accessories, as well as unpainted and uncut duplicates of his Matrix, hands and helmet, for some reason...


This figure is an exclusive to San Diego Comic-Con 2011. The toy comes in a packaging shaped like the Matrix of Leadership, which one could wear around their neck, preferably at the convention itself, so passers-by can exclaim "WHERE THE HELL DID YOU GET THAT?" and then try to get one themselves. The Matrix itself comes packaged in a box that is designed to look like Optimus Prime's chest, and opens accordingly. The chest window doors are sealed with a round magnet.
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.
Also during this time, Micromasters were introduced, and would become one of the last sub-groups of Generation One. Micromasters were tiny Transformers created to compete with the Micro Machines, a hugely popular toy line of the time. While many of the figures had simple transformations and little detail due to their small size, the line eventually expanded to feature Micromaster Transports and Bases, in which Micromasters came with larger vehicles or bases that transformed.
MP-10 Convoy, advertised as a "perfect new model" on its packaging, is an entirely new tooling of Generation 1 Optimus Prime. Convoy is now smaller, making him more in-scale with other recent Masterpiece toys, such as Rodimus, and comes with a trailer and various accessories. While the front of the vehicle mode's cab is an accurate depiction of a mid-to-late-1980s Freightliner FLT cabover, the back half, (which is, as usual, made out of Convoy's legs) is much larger and robot-leggier in proportion. (So much that they sculpt a ladder on each side.)
The "Unicron Trilogy" version of Optimus Prime is a fictional character of this branch of Transformers lore. Appearing in Transformers: Armada, Transformers: Energon and Transformers: Cybertron (known as the aforementioned trilogy), Optimus is the leader of the heroic Autobots. He often converted to his super combat mode. In all three series, Optimus' English voice actor is Gary Chalk, who previously voiced Optimus Primal in Beast Wars and Beast Machines.
Late in 2008, this version of Optimus prime was one of four Classics figures repainted into HasbroToyShop.com exclusives (the other three being the Megatron from this set in G1 colors, Grimlock repainted into Overkill, and Mirage repainted into Dragstrip). Unlike those three, it's debatable just how much repainting went into Optimus, but he comes in a snazzy new box.
The set is a counterpart to TakaraTomy's simultaneously-available Transformers Animated Sons of Cybertron set, which also features translucent versions of that line's Deluxe Optimus Prime and Rodimus figures. It was intended as an exclusive for the Japanese Chara Hobby 2010 festival, but was also initially offered as a raffle prize at the 2010 "Autobot Alliance" event in the Philippines.,[1] and was later available for purchase at Cybertron Con 2010 in Shanghai.

Star Convoy was reissued by Takara in 2005, with some notable alterations to his deco: his white plastic was replaced with metallic silver, and the yellow star on his chest was chromed golden. Star Convoy himself retained some of his original decals but most notably his "simulated head lights" and "wind shield panels" were stamp graphed on him, similarly, Hot Rod's were replaced with the same stamp graphing applications. Additionally, where the original toy had been packaged in robot mode in a tall box decorated with the standard Japanese package art of the time, the reissue was packaged in vehicle mode, in a long, wide box more reminiscent of the original Generation 1 toys.
Part of the first wave of Prime: Beast Hunters Series 3 Cyberverse Commander Class toys, Optimus Prime is an all-new mold. He now transforms into a monstrous, flat-nosed truck with spiky fenders at the front and a cage compartment at the back, and comes with the Thunder Lance and Star Saber. Each of the weapons features two differently-placed 3mm posts, allowing them to be held by his hands, or mount onto two ports on the rear vehicle sides, as well as allowing the lance to additionally be used as a pressure-fired missile launcher.
Transformers Siege Greenlight will be released sooner than later, especially compared to exclusives from previous years. We have our first preorder up on Amazon.ca revealing two important points: who the exclusive retailer is and what the price point will be. Now we know that it will be an Amazon exclusive. While we only know for sure that this will be the case in Canada, it stands to reason that it will be an Amazon exclusive elsewhere to, which is great news since those are always the - Read More
Q-Transformers Optimus Prime is a tiny super deformed toy based on the Alternity Convoy design, transforming into a Nissan GT-R R35, though his legs retain the traditional blue truck bed motif. The English name on the packaging refers to him as just "Optimus". He comes with a code for unlocking "GTR Optimus Prime" as a playable character in the Q-Transformers: Mystery of Convoy Returns game. Standing at only slightly less than one inch and a half, this is actually the smallest transforming Optimus Prime ever made, which is a fairly impressive feat considering the surprising amount of detail in sculpt and paint apps.
In addition to being probably the most popular Generation 2 figure, Laser Optimus Prime was, prior to 2003, a regular contender for most popular Transformers toy ever, back in the days of the annual Transformers fan awards, "The Trannies." The toy won twice, and actually lost once to his repaint, Scourge. The launch of the Armada and Alternators line, along with Masterpiece Prime, saw Laser Prime drop down that list distinctly.
A Deluxe sized version of Energon Optimus Prime. Looks like a smaller version of the Leader class toy, without any trailer or drones. Can Powerlinx with other Energon Autobot toys. This toy was a Toys-R-Us store exclusive in the U.S. and was packaged together with a downsized Energon Megatron. In Japan this toy was packaged together with Kicker and a Star Saber accessory.
This reissue of the original Generation 1 Optimus Prime figure comes in a two-pack with the Deluxe-Class Dark of the Moon Optimus Prime figure. Prime himself is almost identical to the Encore release, save for his trailer hitch which was retooled to allow a peg to be inserted within it while still being able to be inserted into the trailer itself (making it compatible with his G1 trailer and the new trailer included). Like the Encore release, he features lighter colors and tampographed shoulder symbols (which vary slightly from the Encore release).
Optimus Prime also appears in the text-based fiction Dungeons & Dinobots. He commands the Autobots to attack the Arch-Ayr fuel dump. The attack is thwarted when the main Decepticon forces are augmented by the Mayhem Suppression Squad. When Wheeljack attacks both the Autobots and Decepticons with a massive force of drone Dinobots, Optimus offers to allow the outcast Autobot scientist to rejoin the Autobot ranks if the Dinobots destroy the Decepticons. The Dinobots prove unstable and go on a rampage, attacking everyone, including each other. Optimus punishes Wheeljack by having Ratchet painfully reformat him for Earth mode and assigning him to the Ark repair crew on the advice of Side Burn. He punishes Blurr for allowing his heroic Decepticon cousin, Crasher, part of the Mayhem Suppression Squad, to live. When Grimlock returns to the Autobots, Optimus lets him live because the Dinobot has gained useful intelligence and helps in work on the Ark.
The details between these events differ between universes. Sometimes Optimus Prime merged with Vector Sigma soon after defeating the Hate Plague, and returned much, much later as Star Convoy. Sometimes Optimus Prime partnered up with Marissa Faireborn to receive upgrades through mutual kissing. Sometimes... look, he did a lot of weird stuff, okay? He later sacrifices himself to restore the Matrix of Leadership.
 This is an arbitrary line but it is a line that needed to be drawn. There have been many promotional sets over the years which have very few pieces but carry a higher price because of their promotional status. These can range from keychains to individual minifigs to seasonal items. They are not representative of the typical price of a LEGO brick and therefore should not be included in the evaluation.
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.[31][32] 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.[33][34]
The Monster XL also features not one, but TWO barrels with 6 different nozzles per barrel. That adds up to about 36 different ways to put out your best friend's eye. The ludicrous weight and the fact that it takes 43 fucking pumps to get the water up to pressure offer up reasonable disadvantages, but since water gun fights are always half water gun fight and half "who brought the biggest dick" competition, none of that really matters.
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.
In our list of things you didn’t know about Optimus Prime, we learned that the live action version of Optimus was based on actor Liam Neeson. It turns out Michael Bay likes to base his Transformers on real actors, because it’s been revealed that Bumblebee’s character movements are based on Michael J. Fox-- but not just regular old Michael J. Fox; we’re specifically talking about Marty McFly in the Back to the Future movies.
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.

Optimus Prime is usually depicted as being a member of an ancient Transformers race called the Dynasty of Primes, often receiving the title "The Last Prime" in many stories, in which he is depicted as being the last of the Primes. In the Transformers: Covenant of Primus, it was established that Optimus Prime was the last born of the original Thirteen Transformers. It was his unique spark and his inspiring reassurance that "All are One" that allowed the Primes to rally and succeed in their battle against the Chaos Bringer Unicron. When tragedy at last ended the era of the Primes and brought forth the new race of lesser descendant Transformers he alone chose to be reborn in the Well of All Sparks as one of them, that he might know them and their needs more completely. All memory of his past life gone, he took the name "Orion Pax" and sought his way like any other robot on the new world becoming Optimus Prime once more when receiving the Matrix of Leadership when Cybertron faced a new enemy in his former friend, Megatron and his army of followers, the Decepticons. This brings a Great War to their planet of Cybertron. Optimus's origins and personality can vary depending on which "universe" he's seen in. This origin is the most consistent between the various incarnations. Further differences are listed in the respective sections below.
Part of the first wave of battle upgrade Hero Mashers toys, Optimus is a non-transforming robot who can swap any of his parts out with other Hero Mashers figure to create many combinations. He includes his iconic Energon axe, a large projectile-launching gun, another large gun, two missile packs, and an arm for Ultra Magnus. Optimus Prime also has a pointing right hand, which allows you to do a certain Optimus Prime pose in a Dreamwave Productions comic.
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).
In 1984, a volcanic eruption re-activated the Ark, which, in turn, brought the Transformers back on-line. Prime led the Autobots in their opening battles to prevent the Decepticons from plundering Earth's resources, but, following their initial victory, the Transformers were all deactivated by Shockwave. Shockwave killed Prime and leeched the energy of the Creation Matrix from his mind. He used this energy to give life to his creations, the Constructicons. Shockwave was unaware that the Matrix was not just a program in Prime's mind, but a physical object in his chest. Before Shockwave could give life to Jetfire, his next Decepticon, Prime transferred the Matrix energy into the mind of Buster Witwicky. Buster used the energy to turn Jetfire on Shockwave, allowing Prime to reclaim his body and retake leadership of the Autobots. As a reward, he gave Jetfire true life.
Released as part of the Target-exclusive Reveal The Shield subline, this Tiny Turbo Changer 3-pack contains a redecoed Optimus Prime and Bumblebee (in their first non-blindpacked release) and a new Steelbane figure. This version of Optimus features red wheels & Tech Spec-esque patterns on his robot mode chest and... groin-flaps, though the real decoding is on his vehicle mode roof, which when seen through the attached clear-red weapons (or similar plastic device) reveals... an Autobot symbol. Surprise.

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.


Sold at the rather exorbitant price of $75, this re-release of the original Generation 1 Optimus Prime toy is actually one of the most visually different from the other "straight" reissues of the mold, despite Hasbro's assurance that this is the toy you had as a kid. Positively anemic in comparison with the original toy, this Prime's red parts are visibly paler than usual, while his blue parts are much lighter (although the version released at Canadian retail reportedly sports a deeper shade of red again). This shade of blue extends to both Roller (a lighter blue than his traditional dark shade, yet darker than the lightest the figure has been in its history) and the internal workings of his Combat Deck, which is itself a much flatter shade of light grey, compared to its normal dark, swirled metallic silver color. In addition, the toy features the now-customary shortened smokestacks, and the elongated missiles seen on the Commemorative Series release. While all reissues of the Prime mold since 2003 have used the original thick-barreled mold for his ion blaster, this version includes the slender sculpt instead.
If Optimus ordered his troops to come to the humans’ aid, they found themselves taking part in a struggle in futility, as the entire town was near-weightless, meaning they couldn’t put the humans anywhere where they wouldn’t float away once more. Then, the Autobots heard Decepticons approaching. Helpless in their current position, the Autobots were quickly eradicated by the Decepticons.
Ten years after Unicron's defeat, Cybertron was seemimngly at peace, but Optimus still feared another attack from Unicron. Although the Autobot High Council dismissed his fears, a mental link with Primus confirmed that Unicron was still alive. Megatron's disembodied spark, trapped within the chaos-bringer, called out to Prime. Events overtook Prime as Unicron's four Horsemen, Rhinox, Airazor, Cheetor, and Terrorsaur, attacked Cybertron, devastating it. Prime's link with Primus allowed him to upgrade himself into his Energon form and drive them off.
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.
