The world is stunned to see there are now two Hulks -- one the familiar green, the other an angry red. When the original is seemingly defeated, Marvel's greatest champions arrive to subdue this raging engine of destruction -- but Storm, Iron Man, Thor, Ms. Marvel, She-Hulk and Moon Knight fall to his fists of fury. Is there no one who can stop this monster? The Lady Liberators -- the most powerful women in the Marvel Universe, including the Fantastic Four's Invisible Woman and She-Hulk -- arrive for Round 2 while Bruce Banner brings back the Gray Hulk to try and outthink the Incredible Hulk. It all builds to a cataclysmic war between the green and red Hulks! And only one of them will walk away!
