Doctor Mabuse is a fictional character created by Norbert Jacques in the novel Dr. Mabuse, der Spieler and made famous by the three movies director Fritz Lang made about the character; see Dr. Mabuse the Gambler. Although the character was designed deliberately to mimic pulp magazine villains, such as Dr. Fu Manchu, Doctor Nikola, Fantômas, or Svengali, the latter of which was a direct inspiration, Jacques' goals were commercial success and to make political comments, in much the same way that the silent movie The Cabinet of Dr. Caligari (1920) had done just a few years previously.
Dr. Mabuse is a master of disguise and telepathic hypnosis known to employ body transference, most often through demonic possession but sometimes utilizing object technologies such as television or phonograph machines, to build a "society of crime.". Mabuse rarely commits his crimes in person, instead operating primarily through a network of agents enacting his schemes. Mabuse's agents range from career criminals working for him, to innocents blackmailed or hypnotized into cooperation, to dupes manipulated so successfully they do not realize that they are doing exactly what Mabuse planned for them to do.
Mabuse's identity often changes; one "Dr. Mabuse" may be defeated and sent to an asylum, jail or grave, only for a new "Dr. Mabuse" to later appear, as depicted in The Testament of Dr. Mabuse. The replacement invariably has the same methods, the same powers of hypnosis and the same criminal genius. There are even suggestions in some instalments of the series, that the "real" Mabuse is some sort of spirit that possesses a series of hosts.
