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.

Showcase is a comic anthology series published by DC Comics. The general theme of the series was to feature new and minor characters as a way to gauge reader interest in them, without the difficulty and risk of featuring untested characters in their own ongoing titles. Showcase is regarded as the most successful of such tryout series, having been published continuously for more than 14 years, launching numerous popular titles, and maintaining a considerable readership of its own. The series ran from March–April 1956 to September 1970, suspending publication with issue #93, and then was revived for eleven issues from August 1977 to September 1978.
