Collects Fantastic Four (1961) #192-203, Annual (1963) #12-13.

The Fantastic Four have split up! Having gone their separate ways, you might worry we'll have to come up with a new title for this book — but don't, because the Doctor Doom's evil machinations will reunite Marvel's first family for its issue #200 extravaganza! Johnny Storm's hotrod racing, the Thing's demon bashing, Sue's dalliances with Namor and Reed's soul searching culminate in a massive five-part saga that pits the FF against its nemesis in the series' greatest tradition! Who is Doom's son? How does he have the FF's powers? It's a fight to the finish in Latveria! Also featuring Quasimodo the Living Computer, an outer-space adventure with the Inhumans and the return of the Mole Man!
