The Fantastic Four have been fighting Skrulls since their early days - and, somehow, it just never gets old... unlike the FF themselves! An aging ray has three-quarters of the foursome at death's door, but they'll fight the Skrulls to the finish alongside Nova and the Champions of Xandar - at least until a greater threat rises from the Champions' own ranks! The Sphinx is ready to conquer the world, and Mr. Fantastic knows of only one opponent who can stop him: Galactus, who just wants to DESTROY the world instead! Includes the first appearances of Terrax the Tamer and H.E.R.B.I.E. the robot - but which one will prove the greater threat? Also featuring Spider-Man, Medusa, S.H.I.E.L.D., and cameos from across the chronicles of history!
