As Megatron explained that the Matrix was giving them a vision of the future, they witnessed themselves battling on Sherman Dam. The nature of their surroundings established, Megatron resumed the scheduled beating, but a series of setting shifts ended with Optimus reunited with Grimlock. Grimlock handed Prime a sword and suggested he finish Megatron for good. The War Within #5 Optimus found Megatron again, engaging him in combat and announcing that he was playing the game by Megatron's rules now—without mercy. Though he did not slay Megatron, he inflicted enough damage onto him to expunge from his memory the visions the Matrix had granted him. A short time later, Optimus joined the other Autobots in attacking the Decepticons who were trying to use Cybertron's planetary engines. Grimlock was finally impressed with Prime. Thanks to the combined efforts of Optimus and Grimlock's squad, the Decepticons were driven away and the engines were destroyed before they could tear the planet apart. Afterwards, Optimus's group arrived back at Iacon to find it destroyed. Optimus announced the Autobots were no longer evacuating the planet and threw away the Golden Disk full of the knowledge of his predecessors which the council had given him, saying he would choose his own course.

In 2003, Transformers: Armada launched a pivotal new era in the toy line. After several lines of toys produced by one company or the other, Hasbro and Takara united to produce what was purported to be a single, identical line of Transformers for release worldwide. In tandem with this new endeavor, Armada signaled a new continuity in its accompanying animated series and a new focus in both the show and the toys on Mini-Cons, a new faction of Transformers. The Mini-Cons were much smaller robots (not much larger than humans) who were neutral in the Autobot/Decepticon fight, but due to their incredible power and abilities, were sought by both factions.
(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.
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.
