The Incredible Hulk #365

Direct

Hulk heads to Phoenix to try and enlist Reed Richards' help in figuring out his debilitating condition but is attacked by Ms. Marvel (whom he mistakes for a very messed up Thing). Doc Samson arrives at Yucca Flats looking for the Hulk. After conflicts are resolved and testing is done, Reed informs the Hulk that the radiation poisoning in his system is going to kill him when he turns back to Bruce Banner with the rising of the sun.
