Who — or what — is the Cosmic Jailer? What being could be powerful enough to chain Eternity itself? That’s the mystery Galactus must solve — before it’s too late. Ultimate problems require ultimate solutions, and the former World-Eater will call on those who helped cure his insatiable hunger: Captain Marvel, Black Panther, Blue Marvel, Spectrum and Ms. America! Together they are the Ultimates, protectors of the Omniverse. But now they are something more — the newest heralds of Galactus the Lifebringer! And they specialize in the impossible — like the Shaper’s Ghost! Master Order and Lord Chaos! And the terrifying new entity Logos! Meanwhile, Philip Vogt knows the truth — and faces a decision that will either save the Multiverse, or damn it forever! And the Troubleshooters are watching the Ultimates — and they don’t like what they see.
