The Fantastic Four continue their explorations into the impossible - when they confront none other than the Impossible Man!

Then, Reed Richards is replaced by his evil Counter-Earth counterpart. It's a saga so epic in scope that Thundra, Tigra, the Mad Thinker and Annihilus are pulled into it...as Reed battles for his life in the heart of the Negative Zone!
