The Decepticons, feeding off the energy of captured Mini-Cons, are about to begin a hostile takeover of the Transformers' home planet, Cybertron. Do Optimus Prime and the heroic Autobots stand a chance of defending the planet against these super-powered villains? And will the Mini-Cons ever get their freedom back? The action is so explosive that the shockwaves will shake not only Cybertron but even planet Earth right down to the core. All 18 issues of Transformers: Armada are collected in this omnibus.
