19. They've All Died
At one point or another, each member of the Fantastic Four has died (some have even perished multiple times). Reed was presumed dead after a battle with Doctor Doom, Sue was killed due to a mistake by Johnny Storm which he later made right with time travel, and he too was believed dead after facing Annihilus' army alone in the Negative Zone. The Thing meanwhile was killed by a horrified Reed when Ben's body was taken over by Doom.
