"Same As It Never Was"
Continues in X-Men (1991) #98.
In the distant future, the original Fantastic Four are dead. But the world still needs heroes, so Spider-Man, Ghost Rider, Hulk, and Wolverine have taken their place.
After closing of a Negative Zone attack from Annihilus and Blastaar, the team takes some downtime. But it is short-lived, as Doctor Doom seems to have returned from the dead. But the man behind the mask is not Doom, but rather a duplicate brought back online by Arnim Zola.
The Fantastic Four defeat their foes just in time to see Graydon Creed elected as President of the United States.
