After many adventures as the Fantastic Four, Reed married Sue. Not long after that, the team encountered the Inhumans for the first time. They next encountered Galactus and the Silver Surfer. Reed then opened a portal to the Negative Zone for the first time. Soon, the team first battled the Psycho-Man. Before long Reed and Sue had a baby, young Franklin Richards; the team battled Annihilus right before Franklin's birth. Franklin was a mutant with incredible powers, but, due to the cosmic ray alteration to his parents' DNA, they manifested while he was still very young (in the Marvel world, most mutants like the X-Men get their powers while teenagers). Franklin appears to have power that can rival a member of the Celestials; the power of a god in the body of a small child. The couple briefly separated, and Reed further alienated Sue by shutting down Franklin's mind in order to prevent his power from causing global catastrophe; Sue Storm initiated divorce proceedings but the two were reconciled soon after.
