Born in the flames of hell and brought to Earth as an infant to perpetrate evil, Hellboy was rescued from sinister forces by the benevolent Dr. Broom, who raised him to be a hero. In Dr. Broom's secret Bureau for Paranormal Research and Defense (B.P.R.D.), Hellboy creates an unlikely family consisting of the telepathic "Mer-Man" Abe Sapien and Liz Sherman, the woman he loves who can control fire. Hidden from the very society that they protect, they stand as the key line of defense against an evil madman who seeks to reclaim Hellboy to the dark side and use his powers to destroy mankind.
