The original Fantastic Four is together again, just in time to cross paths with a hero who has traveled twenty years into the past in a desperate attempt to save his future from Reed Richards, the madman who is about to change the face of the planet. Oh, and the hero who has come back to save the world? His name is Doctor Doom. Plus: Diablo's back - more dangerous than ever as the potion-toting terrorist declares alchemical warfare on the FF! Making matter worse, the World's Greatest Imaginauts are becoming more and more tired, irritable, delirious...sick! Coincidence...or part of Diablo's nightmarish plan?
