Ralston marketed many breakfast cereals based on cartoons in the 80s and 90s. One of these was Transformers. The Transformers Chocolate Flavored Cereal was a chocolate-flavored concoction, not unlike Cocoa Puffs, manufactured by the Ralston Corporation. However, the cereal was sold only in some parts of the United States and was short lived. The cereal box had Optimus Prime on its cover. The box claims the cereal had "more taste than meets the eye" and also had the ability to "transform ordinary milk into chocolate flavored milk". There also was a mail-away offer for a Jazz toy. The few boxes that still exist are collectables, (one of which went for $349 on eBay).
The use of a G1-based Orion Pax design and an Aligned-based Optimus Prime design with Movie Optimus Prime packaging art makes it hard to know where on the wiki this should go, but given the general movie-themed bent of the Tribute line, we're putting it here. Continuing the tradition, the 2-pack was first released in some Asian countries like Taiwan without any prior announcement from Hasbro itself. A few months after the 2-pack's release, Tribute Optimus Prime & Orion Pax saw worldwide release through Amazon, including an Amazon Japan listing bearing a The Last Knight ID number.
At BotCon 2005, Hideaki Yoke revealed that Optimus Prime (or more accurately, Diaclone Battle Convoy) was not designed by a single person, but rather a team of Takara designers as the one who was originally assigned the job had fallen behind. It is said that a young Shoji Kawamori was also a member of this team at some point, who would design THS-02 Convoy over 20 years later. The patent for the toy, however, lists Hiroyuki Obara as the designer.
The TakaraTomy "Autobot Alliance" release of this toy has some significant differences, including casting the red plastic in a darker shade, making his shin and wheel joints grey rather than Hasbro's bronze, painting the Matrix of Leadership silver, and swapping out the dual energon swords for battle hooks, similar to 2010's Leader class Optimus Prime. However, due to the Japanese release retaining the Hasbro packaging, the box still advertises the dual energon swords rather than the hooks. He retains the masked face used for the Hasbro release.
