A folklore professor becomes unwittingly possessed by the ancient Japanese demons of Thunder and Lightning. But when The Bureau of Paranormal Research & Defense dispatches a team of agents to investigate, a cursed samurai sword sends Hellboy to a supernatural dimension of ghosts, monsters and feudal mayhem.

Now while pyrokinetic Liz Sherman and fishboy Abe Sapien battle one very pissed-off dragon, a lost and cranky Hellboy must find his way home. Even if he can survive the perilous journey, how much crap does a guy have to put up with from the two most vengeful and ferocious spirits of Japanese legend?

Features the voice talents of Ron Perlman, Selma Blair, John Hurt, and Doug Jones.
