The Transformers toyline was created from toy molds mostly produced by Japanese company Takara in the toylines Car-Robots (Diaclone) and Micro Change (Microman). Other toy molds from other companies such as Bandai were used as well. In 1984, Hasbro bought the distribution rights to the molds and rebranded them as the Transformers for distribution in North America. They approached Marvel Comics to create a backstory with names and short descriptions for each character, most of which were written by Bob Budiansky.
Released to conclude the 10th Anniversary of the live-action film series, Masterpiece Movie Series Optimus Prime is a brand new mold that transforms from a 25cm-tall robot (a little taller than MP10 Convoy) resembling how the character appeared in the first live action movie into a Kenworth W900 modified Peterbilt 379, with many of the engineering cues being distinctively based and improved on the ROTF Leader Class mold. His transformation takes a whooping 43 steps, making it one of the most complex Masterpiece figures to date! (Although this pales in comparison to MP-36 Megatron's 107 steps.) .
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.
In April 2007, photos of a repainted Alternators Mirage, in a color scheme similar to Kiss Players Hot Rodimus, and in Alterators-style "fishbowl" packaging began to appear on the internet. Simply called Rodimus, the 27th Alternator lacks almost all of the Kiss Players accessories, including the fishing pole, but keeps the new head sculpt. This figure also sports the classic "flame" detailing in lieu of the Kiss Player's white stripes, while the vanity plate reads "TOO HOT". Rodimus was first sold as a convention exclusive at the 2007 San Diego Comic-Con. The Monday after the convention, it was made available on the Hasbro Toy Shop website, where it would sell out that same morning. The instructions present an alternate name for the figure: Rodimus Prime; whether this is merely an oversight is unknown.
In the United States, Prime was only available in a special two-pack with a similarly unique Classics Megatron toy, and the specially-produced "The Ultimate Battle" DVD (which is, inappropriately enough, entirely about the Unicron Trilogy). The two-pack (including the DVD) was also available as a Walmart exclusive "Bonus Value" version with two randomly selected members of the Cybertron Giant Planet Mini-Con Team, in the combinations Overcast/Longarm, Overcast/Deepdive and Deepdive/Longarm. International markets, including European countries, saw the two-pack in a considerably smaller, differently-shaped box that was lacking the DVD case (the DVD was instead made available separately). In addition, Mexico, Singapore and some European countries such as the Netherlands and Hungary also received the two figures on individual cardbacks. For the United States market, the two-pack was rebranded and re-released in 2003 Universe-branded packaging later in 2007, available from Dollar General, Big Lots and KB Toys, and again in 2010 Transformers-branded packaging in 2011, this time available from Dollar General and Big Bad Toy Store.
A extensive retool of Lockdown, transforming into a Lamborghini Centenario. An exclusive to Walmart stores and part of the "Autobots Unite" subline, While almost the entire figure has been remolded, the lower legs and feet remain unchanged. The figure is overall a bit taller in stature than the base mold and includes extra steps in the transformation which further differentiate the two. Uncommon for deluxe class toys, the figure does not include any weapons or accessories.
