Max brings home a bungling vampire-hunting scientist, Magnus St. John-Smythe, who insists that a new laser gun he's developed can destroy vampires using concentrated sunlight. Magnus' benefactor in the project, however, is Lucard himself, eager to learn if such a gun is possible. Lucard determines that Magnus' invention is a waste of time and money when it has no effect on a vampire colleague. Incensed, he's about to vampirize Magnus, when Gustav and Max barge in and stop him. Later, at Lucard's castle, the vampire colleague suddenly disintegrates and Lucard becomes the proud owner of the world's only delayed-action vampire gun...which he then destroys.
