Years after the events of Predacons Rising, Bumblebee is summoned back to Earth to battle several of Cybertron's most wanted Decepticons that escaped from a crashed prison ship and assembles a team of young Autobots that includes Sideswipe (a rebel "bad boy bot"), Strongarm (an Elite Guard cadet), Grimlock (a bombastic Dinobot)

Beginning with a recap of the coming of the Transformers to Earth and the story of Devastator, the OVA then gets its original story underway, as the Autobots are shown to be in the midst of constructing the powerful "Scramble City," overseen by their newest arrival, Ultra Magnus.

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.
