Hellboy 4: Ragnarok Rising (2025) brings the half-demon antihero back into a dark and apocalyptic world where ancient prophecies collide with modern chaos. The story opens with Hellboy living in relative isolation, haunted by visions of a world on fire and gods long forgotten returning to claim dominion over Earth. These visions are not merely nightmares but warnings of an event foretold in ancient Norse texts: Ragnarok, the final destruction and rebirth of the world. Reluctantly pulled back into action by the Bureau for Paranormal Research and Defense, Hellboy is tasked with uncovering who—or what—is attempting to awaken this cataclysm.

As the plot unfolds, Hellboy discovers that a rogue faction of occultists has uncovered a hidden artifact said to summon Fenrir, the monstrous wolf destined to devour gods and men alike. To prevent the apocalypse, Hellboy must travel across the globe, from frozen Scandinavian ruins to fiery underworld gates, confronting both mythical creatures and his own inner demons. Alongside trusted allies, including Alice Monaghan and Ben Daimio, he faces relentless enemies who seek to hasten the end times for their own twisted visions of power and rebirth.
The stakes rise when Hellboy learns that the ritual to initiate Ragnarok requires his own blood, the blood of Anung Un Rama, the Beast of the Apocalypse. Torn between duty and destiny, he faces the crushing reality that stopping the ritual may mean sacrificing himself or unleashing the very destruction he has sworn to prevent. In this internal struggle, the line between hero and harbinger blurs, giving the film a tragic depth that underscores every battle.

Action intensifies as Fenrir is unleashed, rampaging through a crumbling city while the skies darken and realms of gods and mortals begin to merge. Hellboy, wielding the Right Hand of Doom and ancient runic weapons, engages in a desperate fight not just against the wolf but against fate itself. The climactic confrontation pits him against an alliance of gods, monsters, and zealots, testing not only his strength but his resolve to remain more man than demon.
In the final moments, the world teeters on the edge of annihilation. Sacrifices are made, alliances are shattered, and Hellboy’s choice changes the course of humanity forever. Ragnarok is neither fully stopped nor fully realized, leaving a scarred but surviving world standing at the dawn of an uncertain future. The ending hints at rebirth, suggesting that even in destruction, hope can rise from the ashes, setting the stage for both closure and new beginnings in Hellboy’s saga.
