Once upon a time, Rick Jones was the Hulk's best friend. Rick was there at ground zero on the fateful day the Hulk was born, and during the early days when the Hulk was a mindless brute roaming the New Mexico desert, Rick was right by his side. The only one who believed in him. Now Rick Jones is dead and gone. And the Immortal Hulk wants to know why. But to obtain the answers he seeks, Bruce Banner will have to face roaming gamma experiments, a ruthless assassin out for his blood... and the one thing that can cage the Immortal Hulk.
