Norman Keith Breyfogle was an American artist, best known for his comic book art on DC Comics' Batman franchise from 1987 to 1995. During this time, he co-created the villains Ventriloquist and Ratcatcher with writers Alan Grant and John Wagner, and the characters Anarky, Jeremiah Arkham, Victor Zsasz, and Amygdala with Grant alone. He co-created with writers Gerard Jones and Len Strazewski the Malibu Comics Ultraverse flagship hero Prime, and both wrote and drew the Malibu-published series featuring his original character Metaphysique.

The Ventriloquist is the name of multiple supervillains appearing in American comic books and other media published by DC Comics. All of the Ventriloquist's versions are enemies of Batman, belonging to the collective of adversaries that make up Batman's rogues gallery.
