Hellboy 4: Ragnarok Rising (2025) takes the dark, supernatural saga of the half-demon antihero into its most apocalyptic chapter yet, merging Norse mythology with the grim world of Hellboy. The story begins with Hellboy trying to live a quieter existence, burdened by his past battles and the knowledge of his infernal destiny. However, peace proves impossible when ancient prophecies resurface, foretelling Ragnarok—the end of days—and marking Hellboy as both the catalyst and the only possible savior.

The Bureau for Paranormal Research and Defense uncovers alarming evidence of a cult devoted to awakening the Norse gods of destruction, led by a fanatical sorcerer who believes bringing about Ragnarok will cleanse the world of humanity’s corruption. As Asgardian relics are unearthed, violent portals open across the globe, unleashing frost giants, fire demons, and creatures thought lost to myth. Hellboy is once again pulled into a war he never asked for, caught between his human side and the infernal power within him that the cult seeks to exploit.

Hellboy reluctantly reunites with familiar allies, including the pyrokinetic Liz Sherman and the amphibious Abe Sapien, forming a fractured team weighed down by past losses and mistrust. Together, they must journey to the frozen reaches of Scandinavia, where Odin’s ruined temple hides secrets of immense power. Along the way, they encounter mythical figures, from the trickster Loki, who plays both sides for his own amusement, to the Valkyries, who test Hellboy’s worthiness to fight in the final battle. Each confrontation pushes Hellboy closer to a truth he has long denied—that his fate might not be to prevent Ragnarok, but to embrace it.

As the cult grows stronger, it becomes clear that their leader intends to use Hellboy’s Right Hand of Doom to unleash Fenrir, the monstrous wolf destined to devour the world. The tension escalates when Hellboy realizes that resisting his demonic nature may not be enough; to stop Ragnarok, he may need to wield the very darkness he fears. This internal struggle becomes the heart of the film, exploring whether Hellboy can choose his own destiny or if he is forever chained to prophecy.

The climactic battle erupts at the edge of Yggdrasil, the World Tree, where armies of monsters clash with humanity’s defenders. Hellboy faces Fenrir in a brutal fight that tests his limits, while Liz and Abe battle the sorcerer and his cult. In a desperate moment, Hellboy unleashes his full infernal power, risking his soul to banish the wolf and halt the destruction. Yet victory comes with a price, as the World Tree burns and the balance of realms shifts forever.

The film closes on a bittersweet note, with Hellboy scarred but resolute, walking away from the battlefield as the remnants of Ragnarok smolder behind him. Though the world is safe—for now—his journey remains unfinished, and the question of whether he is humanity’s protector or its doom lingers in the shadows.

Hellboy 4: Ragnarok Rising (2025) blends myth, horror, and explosive action into a dark epic, delivering both spectacle and emotional depth. It challenges its hero to confront not just gods and monsters, but his own identity, making it the most powerful and personal installment of the series.
