Fan Casting What If the Hulk Had The Brain of Bruce Banner?

Bruce Banner, Reed Richards and Charles Xavier constructed an improved version of Cerebro called the Psychotron which merged them physically and mentally into one being, X-Man. They were forced to use it (as it only worked once before blowing up), to defend the world from Galactus. They won the battle, at the expense of all of their super powers, and inadvertently turning Thing into a mindless monster, much like the Hulk.
