Young Hellboy: Assault on Castle Death

In 2023, Dark Horse launched this single-issue one-shot that finds a young Hellboy and his mentor Bruttenholm facing a supernatural siege. Written by Mike Mignola and Thomas Sniegoski with art by Craig Rousseau, it's a compact, standalone adventure that expands the character's formative years. The story offers a focused, action-driven glimpse into Hellboy's early training, blending the series' signature gothic horror with a coming-of-age sensibility.
