Mortimer Kadaver is a murderous criminal possessing a morbid and sadistic obsession with inflicting pain and death. His hideout is filled with a wide variety of means of murder and torture, including an iron maiden, a guillotine, a hangman’s noose, and even a pool of quicklime. Kadaver enjoys feigning his own death by methods such as dressing as a vampire and emerging from a coffin, but he takes even more pleasure in meting out suffering and death to others who cross his path.
