Prime suffered a severe, though unfair, defeat when Megatron challenged him to one-on-one combat while imbued with the different abilities of all the Decepticons. Teletraan I, the Ark's computer, discovered the deception in time, and the Autobots were able to drive off the Decepticons. In "Prime Problem", Megatron created a clone of Optimus, which caused confusion with the other Autobots. Windcharger and Spike, however, were able to identify the clone before it led the Autobots into their demise.
(translated from the Japanese Wikipedia article) The Transformers: Kiss Players was a Japan-only line of Transformers toys, manga, and audio dramas released in 2006. Kiss Players is set in an alternate Transformers universe where the Transformers are powered by the kisses of young girls. The toys themselves come packaged with small, scale figurines of the girls who power them. The toyline was openly admitted to be aimed at a specific part of the market — adults, rather than children. The comic that accompanied the Kiss Players was an unashamed reflection of this, with several images which were considered by some to be very sexually themed.
Optimus Prime (formerly 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. Optimus Prime has a strong sense of honor and justice, being dedicated to building peaceful and mutually beneficial co-existence with humans, the protection of life and liberty of all sentient species. As the current Matrix of Leadership bearer, Optimus Prime is the de facto leader of the Autobots, a faction of a transforming species of synthetic intelligence from the planet Cybertron. The Autobots are constantly waging civil war against a rival faction of transforming robots called Decepticons. According to Bob Budiansky, co-writer of the Transformers series, Dennis O'Neil was responsible for his name.
Dark of the Moon Voyager Class Optimus Prime is an all-new mold. He features heatshield details in his sculpting and translucent solar panels on various parts of his body, and huge gas tanks. Optimus himself is differently proportioned, having larger feet and a smaller torso and arms. He also features some faux-kibble/parts: His actual windshield chest is being covered by a sculpted panel featuring his characteristic deformed windshield-chest, and a pair of sculpted tires on his thighs. His pair of optics is designed to have a light-piping gimmick, but it was rendered useless since it was painted in smoke gray on top of the colorless transparent plastic.
The voice actor drama was written for OFTCC 2004 by Simon Furman, set after the events in the comics. Among those taken from their world via teleportation beam by Unicron and his Decepticon minions were Spy Changers Optimus Prime, Prowl, Ultra Magnus, and Ironhide. The Autobot forces opposing Unicron attempted to deflect a beam, leaving them all trapped on an uninhabited ice-world. The Autobot forces teamed up to overcome the Decepticons led by Reptilion. The Autobots were then, presumably, returned to their own worlds.
In time-honored tradition, Prime's instructions depict the toy with an alternate "pretooled" head – in this case, a version with the faceplate deployed, used on the Platinum Edition and "Rusty" releases of the figure (see below). Additionally, his packaging stock photography depicts him with extra white/silver paint details, especially on his chest and wheel rims, as well as having gray upper arms with red details, among other differences.
