When a university professor opens a forbidden scroll, he becomes possessed by the twin demons of THUNDER and LIGHTNING who seek to return to our world to wake their brothers, the dragons. HELLBOY, researcher KATE CORRIGAN and RUSSELL THORNE, an albino psychic, travel to Japan to investigate.
HELLBOY finds THE SWORD OF STORMS which transports him to a world of Japanese folklore. He learns the sword is the only weapon that can deafeat the demons but also holds the magic that will return them to Earth. The possessed professor sends several creatures of Japanese myth to retrieve the sword. While HELLBOY battles these creatures of folklore, pyrokinetic LIZ SHERMAN and the amphibian man, ABE SAPIEN, battle the monsters that have been unleashed around the world.
