Hellboy: Conqueror Worm

In this 2001 miniseries from Dark Horse, Mike Mignola both writes and draws a pivotal chapter in Hellboy's ongoing war against the occult. The story pits the Bureau for Paranormal Research and Defense against a cosmic threat from Nazi Germany's final, desperate experiments, as a monstrous entity known as the Conqueror Worm is unleashed. Mignola's signature gothic linework and shadow-drenched storytelling give this four-issue arc a haunting, folkloric weight, deepening the mythology of Hellboy's world. It stands as a key entry in the series' early years, showcasing the creator's singular vision at its most atmospheric.
