Melchior von Neumann, also known as Pygmalion, is the middle von Neumann brothers. Melchior is a silent man with a "bent and twisted" personality. He spends a lot of time around Helga von Vogelweide and she seems to be the only one aware of his powers. Melchior can confuse electronic sensors and he can snap Dietrich's puppet strings. Melchior created an army of Auto-Dolls (earning his code name Pygmalion), with the most special one being Siegelind.
