The Bureau made its first appearance in the pages of the Hellboy miniseries Seed of Destruction (4 issues, March–June 1994) and was a major part of the comic until Hellboy leaves the B.P.R.D. at the end of Conqueror Worm. At this point the B.P.R.D. series began, following the agents of the B.P.R.D. such as Abe Sapien, Liz Sherman, Roger and Johann Krauss.
