Kenworth K100 Sleeper Tractor, Red/Blue: Optimus Prime "Rise of the Beasts" 1:24 Diecast Model Truck by Jada

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 the 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 a TV series. His original name is Orion Pax

In the Transformers mythology, Optimus Prime is a Cybertronian, a member of an extraterrestrial species of sentient self-configuring modular robotic lifeforms (e.g., cars and other objects), a blend of biological evolution and technological engineering. He is the primary hero of the story, opposing the Decepticon leader Megatron.
