So far, Johnny has been able to stall the World-Eater, but that luck won't hold forever. What planet will be chosen as Galactus's next victim? Plus, the reintroduction of a fan-favourite Marvel Universe hero into the battle may have caused more problems than it solved, because not even he can save the Fantastic Three from Johnny's newfound might!
