From the introduction: Welcome to a world where the impossible is possible! This is a world that might well be familiar to you, Jumper. Most of it seems to be the same ol, same old plain earth you know of, but what is surprising about this place is the first family of Marvel, in more ways than one. Welcome to the world of Fantastic Four, Jumper. This might be a world where the four are the only special beings on earth, or it might be one where all sorts of marvel properties lurk just under the surface, there’s no real way to tell. You arrive just as the Four and Doom finalize their plans to go into space.
