Francis Dolarhyde

Francis Dolarhyde is a fictional character and the main antagonist of Thomas Harris' 1981 novel Red Dragon, as well as its film adaptations, Manhunter and Red Dragon. Dolarhyde is a serial killer who murders entire families every full moon. He is nicknamed "The Tooth Fairy" due to the nocturnal nature of his crimes, his tendency to bite his victims' bodies, the uncommon size and sharpness of his teeth and other apparent oral fixations.

He kills at the behest of an alternate personality; he refers to his other self as "The Great Red Dragon" after William Blake's painting The Great Red Dragon and the Woman Clothed in Sun. He believes that killing people—or "changing" them, as he calls it—allows him to more fully "become" the Dragon.
