"Hercules, thought dead by his friends and colleagues, has returned from exile with more power and a warning: the Chaos King is coming! Since the end of Secret Invasion, the Chaos King has amassed his army of alien slave gods--and the time to strike Earth is now. Only the greatest Marvel heroes can oppose him--led by the god of heroes, Hercules! But are Herc's incredible new powers and the reassembled God Squad enough to stand against the greatest threat the Marvel Universe has ever seen? Can they stop a mad god who seeks to destroy reality itself, or will the Chaos King bring the heroes of Earth to their knees?"--Page 4 of cover.
