Rotwang is a mad scientist. He lives in the middle of Metropolis in an ancient house said to be built by a wizard. He invented the The Machine Man. Rotwang has a secret way to view the doings of the poverty-stricken below. In one scene, he takes Johann Frederson to view the people below at the underground church, where Maria tells the Biblical story of the Tower of Babel. Rotwang captured Maria to transform The Machine Man into a false version of her. In the finale, he falls down to death from the top of The Cathedral. He was killed by Freder Frederson.
