Occurence: Incredible Hulk Annual #5

The Hulk is fighting the classic creature Goom who uses his Molecular Condenser Beams to shrink the Hulk to the size of a mouse. Goom's unbreakable mental will power is what keeps a person small once Goom uses his beams. The Hulk's will power overcomes Goom's powers and the Hulk grows back to normal size, much to Goom's surprise.
