Bruce Banner discovers that the Hulk hides a terrifying and unexpected ability: when night falls, he can return from the dead. This immortality draws Banner into a series of events involving scientific experiments, conspiracies, and supernatural horror, while different Hulk personalities begin to resurface. Hunted by enemies seeking to understand or exploit his power, Bruce gradually uncovers the mystery of the Green Door, a phenomenon tied to the very origin of gamma-powered beings. Alongside allies such as Betty Ross and Rick Jones, he must confront his trauma, his fractured identities, and a threat that reaches far beyond his own existence. Blending body horror, mythology, and introspection, the series presents Hulk as both a mystery to understand and a monster to fear.
