Hellboy Animated are original straight-to-DVD animated films based upon the Hellboy comic books by Mike Mignola. Both films, Sword of Storms and Blood and Iron, received the signature of Mike Mignola and Guillermo del Toro. A third film was being planned but was never greenlit.
Ron Perlman, who played Hellboy in the live-action movie, also provides the voice of the character in the animated version. Selma Blair and John Hurt also reprise their roles from the film of Liz Sherman and Professor Trevor Bruttenholm, respectively. The voice of Abe Sapien is Doug Jones, who played Abe in prosthetic work in the live-action movies but did not provide the voice for the first film - Abe's vocals for that film were done by David Hyde Pierce - he did, however, voice the character in the second film. Kate Corrigan is voiced by Peri Gilpin.
Music is by Christopher Drake.
In Sword of Storms, Hellboy and Kate Corrigan are dispatched to Japan to solve the mystery of a professor possessed by the Japanese demons Thunder and Lightning. The demons wish to get their hands on a powerful haunted sword, which will free them, and allow them to unleash their brothers and destroy the world. While Hellboy is sent into an alternate dimension, facing Yokai on the way, his B.P.R.D. teammates, Abe Sapien and Liz Sherman, try to stop one of the Dragons on the first wave of the coming chaos.
