In "World War Hulk" #1, Reed is shown with Tony Stark as Iron Man. Both men were trying to convince Sentry to fight the Hulk, thinking that the calm aura that the Sentry produces may be able to stop the Hulk's rampage. In "World War Hulk" #2, with the aid of the rest of the Fantastic Four, Storm, and the Black Panther, Reed is able to create a machine that projects an image of the Sentry and recreates the hero's aura of calm. He uses the machine on the Hulk just as he is about to defeat the Thing, but the Hulk knows it is not the real Sentry and destroys the machine. In a last line of defense, Sue Storm tries to protect her husband by encapsulating the Hulk in an energy field while pleading with him to spare Reed. The Hulk does not listen and is able to easily exert enough strength against her force field to cause Susan to collapse and experience a nosebleed from the stress, before she dooms Reed to the Hulk's wrath.
