Optimus Prime
For the "Generation 2" toy line, the original Optimus Prime toy was altered somewhat and an electronic sound maker was added. Later "Generation 2" toys of Optimus were completely new designs, such as Combat Hero Optimus Prime, Laser Optimus Prime, and Gobot Optimus Prime, who could become a red Lamborghini car. In 2003, Takara introduced the Masterpiece MP-01 Convoy/Optimus Prime. While retaining the original concept of a transforming semi-trailer truck, this die-cast figure 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 Hasbro and Takara Tomy 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 "Alternators" 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.
