Collects Immortal Hulk (2018) #11-20. The Green Door is completely open and Hell has ascended in New Mexico. Now the ruler of Hell has come to collect. It whispers through many mouths. It destroys with many hands. Its only weapon is hate. It wears human souls like masks to work its will. But in the lowest hell, underneath all others, all the masks come off — and The One Below All is finally revealed! Bruce Banner belongs to him. But the Hulk...not even Hell is strong enough to stop his horrific anger. In another life Rick Jones was the Hulk's best friend. He was there on the fateful day the Hulk was born. When the Hulk was a mindless brute, Rick was the only one who believed in him. But now Rick is dead and his body has been exhumed and stolen! And the Immortal Hulk wants to know why. To find the answers he seeks, Bruce Banner will have to face roaming gamma experiments and a ruthless assassin out for his blood. And when the Immortal Hulk is depowered it may be time for the return of Joe Fix-It! The fan-favorite run that's redefining Hulk mythos gets even more intense!
