The ultimate toy: The Cosmic Control Rod. It's in the hands of a nameless fiend who is understandably reluctant to give it back. If that isn't enough, consider this: A portal has been opened into the Negative Zone, the anti-matter universe that borders our own. Blastaar wants the Cosmic Control Rod for his very own, and has a massive armada poised to invade Earth from the Zone. Only one thing, a S.H.I.E.L.D. nuclear warhead, can close the gateway.
