Optimus Prime, also known in Japan as Convoy, is a fictional character and the protagonist of the Transformers franchise. Generally depicted as a brave and noble leader, Optimus Prime is the supreme commander of the Autobots in their fight against the Decepticons. The Transformers characters were developed for an American market after Hasbro representatives visited the 1983 Tokyo Toy Show. The characters were modified and the coloring was changed; notably, Optimus Prime was colored red, chrome, and dark blue. The popularity of the Transformers toys resulted in comics, movies, and even a TV series.

Transformers is a media franchise produced by American toy company Hasbro and Japanese toy company Takara Tomy. It primarily follows the heroic Autobots and the villainous Decepticons, two alien robot factions at war that can transform into other forms, such as vehicles and animals. The franchise encompasses toys, animation, comic books, video games and films. As of 2011, it generated more than ¥2 trillion in revenue, making it one of the highest-grossing media franchises of all time.
