Synopsis for "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.
- Sue states that Bloomingdale's gives a special discount to superheroes' wives.
- Uatu learns that there was another way to defeat Galactus instead of giving up the Ultimate Nullifier.
- The principal scenario, the Hulk being massive, green-skinned, and incredibly strong, while keeping Dr. Banner's memories, personality and intellect, was explored in the mainstream continuity, the MCU, and several other realities after this comic was first published. Banner under this state is usually called, officially or otherwise, "Professor Hulk."
