Editing Mister Fantastic (section)

====Vol. I #6====
In ''What If?'' #6 (Dec. 1977), after the team are exposed to cosmic rays, they develop powers based on their personalities. Reed Richards' vast intellect causes him to become a giant floating brain, and he takes to calling himself "Big Brain". Reed's brain is destroyed during a battle with [[Doctor Doom]], but not before he manages to transfer his mind into Doom's body. This version of the Fantastic Four reappeared in the Volume II story arc 'Timestorm', summoned by the Watcher to persuade the man who would become Kang/Immortus not to become a threat. Richards' and the other members of his Fantastic Four are killed by Immortus.<ref>''What If?'' vol. 2 #39 (July 1992)</ref>
