Dr. Doom has returned from his spaceborn exile. His asteroid drifted to the planet of the Ovoids, who were technologically advanced and highly trusting, and taught him how to switch bodies with someone else. After being transported back to Earth, he exercised this ability to trade places with Reed Richards and take his place among the Fantastic Four. Will the others see through the disguise soon enough?
