Hulk accidentally destroys a building before turning back into Banner as day breaks. A local resident thinks the Gray Hulk is actually a mutant and calls X-Factor to apprehend him. X-Factor arrives but Banner thinks they're from Gamma base and runs away. They chase after and as darkness sets Bruce turns back into Hulk who is not in a good mood. After a huge battle in a large printing press, Iceman uses his increased powers (from Loki in Thor #377) to imprison Hulk in a solid block of ice and they call SHIELD to come retrieve him.

Note: The fight between Hulk and X-Factor occurs in the massive Spartan Printing Company building in Sparta Illinois, where almost every comic book in North America (including the entire Marvel line) was being printed at the time.
