Optimus Prime, , is a fictional character in the Transformers franchise. The Transformers characters were developed for an American market after Hasbro representatives visited the 1983 Tokyo Toy Show.

The popularity of the Transformers toys resulted in comics, movies, and a TV series. In the Transformers mythology, Optimus Prime is a Cybertronian, an extraterrestrial species of sentient self-configuring modular robotic lifeforms (e.g.: cars and other objects), a synergistic blend of biological evolution and technological engineering. In almost every version of the mythos, Optimus is the leader of the Autobots, a faction of Transformers who are rivals of the Decepticons, another faction. He is defined by his strong moral character and is almost always portrayed as the primary hero of the story, opposing the Decepticon leader Megatron. Over the history of the Transformers franchise, Optimus Prime has been portrayed by a variety of actors, such as Peter Cullen, Garry Chalk, Neil Kaplan, David Kaye and Jake Tillman. Animated character biography Optimus Prime (formerly known as Orion Pax) is constantly, if not always, depicted as having strong moral character, excellent leadership, and sound decision-making skills, and possesses brilliant military tactics, powerful martial arts, and advanced extraterrestrial weaponry.
