The power of the Matrix is gone, its energies unleashed with the triumphant return of Optimus Prime. Now, in the final chapter of the Generation 1 saga, both heroes and villains will undergo one final "transformation" with the fate of three worlds hanging in the balance!
A calm has settled across the warring factions, although even now the Decepticons are plotting the theft of an ancient Cybertronian artefact. This artefact will lead the sentient giants to a distant world known as Nebulos, a planet held in the tyrannical grip of The Hive. On this alien world, a small band of rebels fight for the liberation of its people from their cruel masters and their machines. How will the arrival of these extraterrestrial robots, each with their own allegiances, change the course of the conflict and lead to a starting rebirth that will alter the mighty Autobots and cruel Decepticons forever?
Witness the conclusion of Transformers: Generation 1 and the next step in the evolution of these icons of animation!
