Plot
Lee and Kirby set the standard for out-of-this-world imaginative adventure and launched the Marvel Universe in the pages of Fantastic Four. Now, with all the MU super hero players in place, it's time for the FF to run the gauntlet. The Thing throws down with the Hulk in a battle so huge it takes the combined might of the FF and the Avengers to stop it! The Sub-Mariner makes a play for Sue Storm! The FF tangle with the X-Men! Nick Fury drops by in the story that set the table for "Agent of S.H.I.E.L.D."! And even Doctor Strange makes an ever-so-astral appearance!
