At the end of World War II, the Nazis attempt to open a portal to a paranormal dimension in order to defeat the Allies, but are only able to summon a baby demon who is rescued by Allied forces and dubbed ''Hellboy'' . Sixty years later, Hellboy serves as an agent in the Bureau of Paranormal Research and Defense, where he, aided by Abe Sapien, a merman with psychic powers, and Liz Sherman, a woman with pyrokinesis, protects America against dark forces.
