Legends Class Optimus Prime is based on his original Generation 1 appearance. He features a fake grill for his robot mode, and his large legs result in a fairly thick and compact truck bed. He is part of "Reveal the Shield", a subline that outfits all its toys with rubsigns, and in this case, it's located on the left side of the truck/his left elbow.
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.
After many battles on Earth, Optimus died by standing purposefully in the path of the Hydra-Cannon built by Megatron from the three Mini-Con weapons, the Star Saber, the Skyboom Shield, and the Requiem Blaster. He managed to partially reflect the beam, damaging the Hydra-Cannon. It was the Mini-Cons themselves, however, who resurrected him, entering the Matrix and reconstructing a new body for him. Subsequently, Unicron forced Optimus to face the dark part of his soul and that, on some level, he enjoyed the thrill of combat. Following Unicron's defeat, Optimus's denial was sorely tested as Galvatron, an upgraded Megatron, forced him into one final furious battle. The battle ended when Starscream sacrificed himself to end the circle of hate that powered Unicron. Floating through space, Optimus found the Matrix, but said he did not deserve it. Before beginning the battle with Galvatron, he was upgraded by the minicons. His red torso turned black and he was able to battle Galvatron one on one.
Part of the fifth wave of Kabaya's revival of the Transformers Gum series, this snap-on transforming model kit of War for Cybertron Optimus Prime is sculpted from red, light blue, and gray plastics, and uses stickers for detail. He comes with a blue non-transforming version of his hand-held blaster rifle, which mounts at the rear in vehicle mode. He comes packed with a model kit of Tigerbreast, and a stick of gum.
The Decepticons' initial strike came abruptly and brutally, devastating entire districts of Metropolis. Optimus was meeting with Hot Rodimus as this took place, and was nearly overcome with grief when Ratchet informed him of the carnage the Decepticons had wrought. Steeling himself, Optimus coordinated the city's defenses, ordering his troops to be dispatched where they were most needed to repel the invasion. Upon spotting an old enemy on one of the nearby monitors, Optimus geared up to go in the field himself. Arming himself with his favorite pistol, Optimus resolved to take down Megatron. Raid
When I was a child in the 1960s, I bought most of my own Lego, using money from paper routes I had from the ages of 7-16. But the items I bought we not ‘kits’. They were small boxes of standard bricks. Each box contained only a single shape and colour, but you could find most of the basic shapes 1×1 or 1×2 or 1×4 or 1×8, 2×2 or 2×3 or 2×4, bevels, doors or windows, if you found the right box. The boxes were only 50 cents, and had an average of 12 bricks per box. That works out out to about 4-5 cents per brick. The kits were expensive, but buying the standard boxes was a lot cheaper, and that is what most people did back then. With my paper route, at the age of 7 I could buy 100 pieces per week using my own money. Name any 7 year old that afford to do that now!
Certainly the most iconic, and most common, leader of the Autobots is Optimus Prime. But the thing about Optimus Prime is that he dies... a lot. And every time he dies, someone has to take his place-- until he’s invariably resurrected in one way or another, that is. In many storylines, including the original animated Transformers: The Movie, it’s Hot Rod who takes over as Rodimus Prime.
Part of TakaraTomy's Movie Advanced Series lineup, Revenge Optimus Prime is redeco of the 2010 Transformers Battle Blades mold, featuring darker plastic, a pair of flip-out swords (the first release of this mold) from the Hasbro release, and chromed fuel tank-guns & sun visors. His shins & wheel joints are bronze from the Hasbro release as opposed to the grey of Takara's Autobot Alliance release.
The third version  would quite possibly have been the most gimmick loaded Transformer in the history of the line, simultaneously being a Powermaster, Headmaster, and triple changer. The Headmaster also would have been a triplechanger, turning into a sort of armored four-wheeled rover (Roller II?) and robot as well as a rather silly looking Optimus Prime head with four vertically aligned wheels jutting off the sides. It seems that when the extra Headmaster gimmick was scrapped, the super mode head remained separate rather than being reintegrated into the trailer hitch such as on the earliest design. Notably, the body of this design is extremely close to the final design.
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.
In a rare move, there were no brick and mortar store exclusives in Western markets for the regular Prime line. The "Rust in Peace" special edition of Terrorcon Cliffjumper was available at San Diego Comic-Con and Hasbro Toy Shop, while the "Dark Energon" series of translucent redecos was sold by online retailer BigBadToyStore. All of the "Dark Energon" toys were available at general retail in Singapore and Malaysia, and the Voyager Class figures were also available at general retail in the Philippines.
Optimus and Prowl secretly guarded a shipment of microchips that could be used to imbue sentience onto robots. Posing as the lorry transporting the precious cargo across the Yorkshire Dales, he was attacked by Megatron and Rumble who sought the microchips to create an army of Decepticons. With your help, Optimus may or may not have been successful in keeping the microchips out of the Decepticons' hands. Highway Clash
Prime would make one further surprise appearance in Dreamwave's Transformers: Armada comic series, although it would not be the Prime of Dreamwave's first series. When the Optimus Prime of the Armada universe disappeared, pulled into another dimension by the power of Unicron, the Chaos-Bringer sent something back in his stead: a nearly dead Optimus Prime from that universe, who warned the transformers of Unicron's coming into their universe before dying.
Apart from this, Optimus Prime is also the weakest link of the gestalt combination, due to a number of design failures attributed to his torso mode. The square holes-and-tabs used to secure the arms together when in torso mode are too weak to remain locked in place (though a very small amount of copies can secure the arm well), and are prone to falling out of position should an attached arm be moved. The torso mode's skirt plate is also attached to the stomach rather than the pelvis, rendering the waist swivel nearly worthless due to the skirt obstructing articulation.
In an alternate version of this reality, Rodimus was forced to deal with a militant and aggressive Optimus Prime, and Cybertron was soon wracked by a three-way war between Optimus' Autobots, Rodimus' Omnicons, and Megatron's Decepticons. Unfortunately, the balance of the conflict tipped with the arrival of dimension-hopping tyrant Megazarak, whose Destructicons allied with the Decepticons, creating a force that soon annihilated Autobot and Omnicon alike. However, the Destructicons then turned upon their allies and destroyed them before being abducted by Unicron. This universe was then drained of all life and energy by Tornedron, whose creator Primacron was also destroyed.
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.
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.
