Based on Michael Mignola's popular comic book series about a secret military unit that battles evil supernatural forces, the animated HELLBOY: SWORD OF STORMS follows the team to Japan, where a professor has become possessed by the twin demons of thunder and lightning, who were imprisoned long ago within a magical sword. The title character, Hellboy (voiced by Ron Perlman, who also starred in the live-action film), is the team's strongest member and its biggest secret, because he's a real demon, captured as a baby and raised to fight for good. With bright red skin, horns, a resistance to flame, and plenty of attitude, Hellboy has no patience for evil spirits. When Hellboy picks up the weapon, he's transported to a mystical land populated by monsters straight out of Japanese mythology who urge him to break the sword and free the demons. Though doing just that is Hellboy's only way back to the real world, the two vindictive spirits will almost certainly destroy the planet if loosed.
