Hulk's archenemy the Leader causes Banner to transform back into the savage Hulk, and Banner, once again, becomes a fugitive. General Ross is seriously injured when the Hulk runs amok while battling the Rhino, and Glenn Talbot promises Betty that the Hulk would pay for it. As a result of the failed wedding and Banner's relapse into the Hulk, Betty suffers a nervous breakdown and is hospitalized. In an effort by the Sandman to rid himself of his glass like form, the Sandman orders the Dr. Marquand to provide him with a patient with the same blood type as him which turns out to be Betty Ross.

MODOK tells the Harpy where to find the Hulk and she flies off in search of him. She ambushes him and, after a lengthy fight, knocks him out with her hellbolts. Before she can take the Hulk back to MODOK, however, they are abducted by the Bi-Beast to his city in the sky. Banner agrees to repair the machines that cause the city to float in exchange for permission to use
