Unicron was a fallen god from before the universe existed, who sought the ultimate peace that would be granted by the destruction of all life. Amazingly, Unicron accomplished this task, wiping out all life, planets, stars and nebulae, even "the stuff of space itself" in the universe and leaving only nothingness and void. His lust for destruction finally sated, Unicron entered a deep sleep - but he had not been thorough enough. Tiny fragments of the old universe reacted with each other, and a new universe was born. As Unicron slept, the core of this new universe - somehow a sentient being - became aware of Unicron's threat and created a defender to battle his evil - Primus, the lord of light. Unicron awoke to find himself surrounded by another universe, and simply began to destroy it again.

It is the year 2005. Twenty-one years after the heroic Autobots and the evil Decepticons resumed their neverending war on planet Earth, the Decepticons have conquered the robots' home planet Cybertron. After a surprise attack by the Decepticons, both factions wage a gruesome battle at Autobot City. In the midst of the battle, Autobot leader Optimus Prime dies during his fight with Decepticon leader Megatron. The Autobot Matrix of Leadership is then passed on to second-in-command Ultra Magnus. Meanwhile, a badly-damaged Megatron is jettisoned by Starscream into deep space, where he encounters the planet-eating robot Unicron and is reborn as Galvatron, the new Decepticon leader. With Galvatron's reign on the rise and Unicron's imminent arrival within Cybertron's orbit, the Autobots must act quickly and protect the Matrix or face total annihilation.

Episode 43.5, "Distribution", is a comedic special show which commemorates 500 episodes of Transformers in Japan (however, since that total includes assorted Japanese series, the west is still some distance away from this number). When aired in Japan, it did not air in the usual timeslot for Superlink, and is not in any sort of chronological order - It features the Autobots playing a video game training simulator, which they certainly do not have time to do between episodes 42 and 44.
