When a mysterious gamma outbreak begins infecting people across South Korea, Amadeus Cho (now a more seasoned Hulk) returns home with his friend Hercules to investigate. But what begins as a science-based mystery spirals into a personal crisis when his mother, Dr. Helen Cho, is targeted by a rogue biotech cult seeking to unlock her gamma research. As gamma anomalies spread, Amadeus must face ghosts of his past, question the limits of control over his Hulk form, and protect the one person he can’t afford to lose. The line between science and monster grows thinner with each decision.
