"Freedom is the right of all sentient beings" reads the quote from the original Optimus Prime's bio cards, a sentiment without which we wouldn't be here today, leaving him off of a list of the best transforming Optimus Prime toys.
It seems that the arrangement that Ceji and Hasbro Bradley came to involved Ceji manufacturing a large number of Optimus Prime toys in their own facilities on behalf of Hasbro Bradley, which is why you will see so many Optimus Primes in Europe sporting a "MADE IN FRANCE" copyright on the toy, and associated copyright text on the packaging as well. These toys are believed to have seen release in the UK as well as mainland Europe. In Europe in late 1985 they would have come packaged in Milton Bradley 'MB' boxes and later in 1986 in Hasbro Europe packaging.
For the toy line, the original Optimus Prime toy was altered somewhat and an electronic sound maker was added. Later toys of Optimus were completely new designs, such as Combat Hero Optimus Prime, Laser Optimus Prime, and Optimus Prime, who could become a red car. In 2003, Takara introduced the MP-01 Convoy/Optimus Prime. While retaining the original concept of a transforming semi-trailer truck, this incorporated modern toy manufacturing techniques for improved detail and articulation, while, at the same time, captured the look of the cartoon character. It has since been released by both and in different variations. In 2010, a version of the Masterpiece toy, called Masterpiece Convoy Sleep Mode, was released, painted in dark colors to match the appearance of Optimus Prime after his death in the 1986 film. In 2006, Hasbro introduced Optimus Prime, which turned into a licensed 1:24 scale model Dodge Ram SRT-10. In 2011, Takara Tomy released MP-10 Convoy, a smaller, more show-accurate version of the Masterpiece Optimus Prime figure.
