The Maschinenmensch ( German for "machine-human") is a fictional character in Fritz Lang's film Metropolis, played by German actress Brigitte Helm in both its robot form and human incarnation. She is a gynoid (female robot or android) created by the scientist Rotwang. Named Maria in the film, and "Futura" in Thea von Harbou's original novel Metropolis, she was one of the first robots ever depicted in cinema.
The Maschinenmensch has been given several names through the decades: Parody, Ultima, Machina, Futura, Robotrix, False Maria, Robot Maria, Roboria and Hel. The intertitles of the 2010 restoration of Metropolis quotes Rotwang, the robot's creator, referring to his gynoid Maschinenmensch, literally translated as "Machine human".
