Langdon Everett Caul
Langdon Everett Caul is one of Dark Horse's most intriguing figures lurking in the shadows of Mike Mignola and John Byrne's richly atmospheric Hellboy universe, first surfacing in Hellboy: Seed of Destruction #2 back in 1994. Over more than three decades, this Copper/Modern Age character has woven through the pages of B.P.R.D. and its landmark storylines — including the collector-prized B.P.R.D.: King of Fear — sharing that strange, haunted world with icons like Hellboy, Abe Sapien, Liz Sherman, Johann Kraus, and Kate Corrigan. With 77 appearances spanning all the way to 2025, Caul is the kind of deep-catalog discovery that rewards fans who dig past the headline names into the layered mythology Mignola has spent a lifetime building. If you love the uncanny corners of the Hellboy cosmos, this is a name worth knowing.
