Prime suffered a severe, though unfair, defeat when Megatron challenged him to one-on-one combat while imbued with the different abilities of all the Decepticons. Teletraan I, the Ark's computer, discovered the deception in time, and the Autobots were able to drive off the Decepticons. In "Prime Problem", Megatron created a clone of Optimus, which caused confusion with the other Autobots. Windcharger and Spike, however, were able to identify the clone before it led the Autobots into their demise.
Upon witnessing the incredible power of a lightning storm for the first time, Optimus Prime had Sparkplug Witwicky explain the phenomenon to him. Intrigued by the potential of lightning, Prime put Huffer and Gears to work finding a way to harness its energy, so they could use it to aid in the rebuilding of their spaceship. Huffer constructed a giant lightning rod, and Optimus Prime and the Autobots gathered to watch its first test. They were shocked, however, when a fleet of battered, damaged Decepticons flew out of the mountain housing the antenna and off into the night. The evil robots had attempted to discover the device's secrets and been seriously electrocuted! Once the lightning rod had been checked, Prime vowed to make the lightning-harnessing technology the Autobots' gift to Earth once they had left the planet. Autobots' Lightning Strike
Optimus Prime comes with many accessories in addition to the aforementioned Matrix, including the character's traditional laser rifle, now termed (and henceforth known as) an ion blaster. The initial release of the figure cast the ion blaster in grey plastic, but later assortments recast it in its more familiar black coloration. Other accessories include a transparent orange energon-axe that plugs into either wrist when Prime's fist is retracted, and even a non-transforming gun mode Megatron weapon, with removable stock, silencer and scope accessories, in homage to several instances in the Generation 1 cartoon when Prime was forced to wield his enemy. Pack-in bonuses that came with the figure included an inner cardboard tray illustrated to resemble the interior of Prime's Combat Deck, and in later releases, a small poster drawn by Pat Lee.
This Wal*Mart-exclusive two-pack pairs the deluxe-size Classics Optimus Prime figure with live-action movie line's Fast Action Battlers Power Hook Optimus Prime toy. Both toys are identical to their original releases, and together represent the Optimus Primes of the oldest and newest generations (at the time) of Transformers, respectively. The movie Prime is designated "2007 Optimus Prime", while the Classics figure is dubbed "1984 Optimus Prime" (referring not, of course, to the toy, which was produced in 2006, but to the character).
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.
Released as part of a collaboration between Transformers and Primitive Skateboarding, this figure is a black repaint of the Titans Return Powermaster Optimus Prime, with the deco somewhat resembling Nucleon Quest Super Convoy, but with some gold trims and Primitive Skateboarding markings partially designed by Primitive Skateboard founder Paul Rodriguez. He also comes with an extra ramp and skateboard accessory that resembles the one Daniel Witwicky used in The Transformers: The Movie, which Shreddicus Maximus (or any other Titan Master) can attach to. The ramp can also form Optimus Prime's gun.
Movie the Best Nemesis Prime is a redeco of the TakaraTomy exclusive Calibur Optimus Prime figure, with darker paint and plastic, and bright, metallic, purple eyes, and the mark of Quintessa on his face. As for the weapons, the Caliber Axe uses translucent purple plastic instead of orange, and there is more silver at the base of the blade. The Overshield has black replacing the original's silver and purple replacing the original's bronze.

On the battlefield, there are few who rival Optimus Prime's prowess. He is easily the strongest of any Autobot his size, and his ion blaster and energon-axe are deadly weapons. He would sacrifice his life to protect his fellow Autobots or those under their care and does so on a regular basis. His compassion for other sentient beings is his only real weakness, and one the Decepticons have taken advantage of time and again... though it's also the source of his strength!
Like Chomp & Stomp Grimlock, his truck kibble from the back can accommodate One-Steps and Power Battlers (Both Hasbro and TakaraTomy), activating his various voice clips and flashing lights by interacting with the magnets in their feet. He is notably less kibbly than other AOE Optimus Primes...from the front, at least. The back and sides are not so promising with large chunks of Western Star truck kibble hanging off his legs, making him look as if he's wearing a petticoat. At least the jetpack helps balance the whole thing out....
Prime's cab and trailer can also combine to form a super robot mode. Transforming the cab into the torso portion sends the transformation command to the trailer, which raises itself up off the ground to become a pair of immobile, statuesque legs (as long as you're not playing with it on carpet), and when the pair are connected, the super-robot head pops up with a metallic shriek sound effect. Pressing the Autobot symbol on the figure's chest activates a pulsing laser sound effect, and the small grey button on his right shoulder illuminates his fist with a red LED, which can illuminate either of his guns, as well as the Star Saber sword (the Star Saber was specifically cast in clear plastic for this purpose, but in practice, the light failed to carry even halfway up the blade).
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.
The first toy in TakaraTomy's United toyline is a redeco of the War for Cybertron Deluxe Class Optimus Prime, transforming into a Cybertronic "armored truck". As has been TakaraTomy's wont of late, he now sports a metallic red paint job, with brighter pink paint applications and cooler grey parts, and features several additional paint details to those present on the Hasbro figure in the form of black chest windows and pink lines on his face mask. His rifle transforms as well, folding and plugging into the roof of the vehicle mode. The rifle can also peg into his forearms, and, in its compact configuration, can attach to his shoulders via peg holes on the backs of his front tires or stored behind his back in robot mode.
An extremely simplified version of Optimus Prime, this McDonald's Happy Meal toy transforms into a trailer-less truck cab. He is formed out of a large percentage of translucent plastic, and can combine with the other Happy Meal Armada toys (Hot Shot, Red Alert, and Smokescreen) into a human (well, robot) pyramid-style configuration, notionally considered a "Mighty Robot".
As the final new-design Optimus Prime toy from the original Generation 1 era, the Japanese-exclusive Star Convoy was a significant departure from previous versions. This incarnation of Prime transforms into an extended-hood cab truck of made-up model pulling an implausibly large trailer, incorporating the motorized "Microcarrier". Powered by four AA batteries, the Microcarrier drives Star Convoy either forward or backward, spinning a radar dish mounted on the rear of his trailer as he rolls along. Prime's teammate in the Battlestars, Grandus, can link up to the rear of Star Convoy's vehicle mode and be pulled along behind him; Sky Garry can then land atop Grandus, forming a giant vehicle.
In robot mode, like Combat Hero Prime, the bottom of the truck became his familiar windowed chest based upon the original Optimus Prime toy. His main gimmick was light up LED headlights, and a lightpipe in the bottom of his right fist, illuminated by an LED in his right forearm, that would illuminate his clear sword or his double-barreled rifle if they were used in that hand. All three LEDs were activated simultaneously by pressing the sunroof-like depression on the roof of the truck.
