Luke Cage was created by Archie Goodwin and John Romita, Sr. shortly after Blaxploitation films emerged as a popular new genre. He debuted in his own series, Luke Cage, Hero for Hire, which was initially written by Goodwin and pencilled by George Tuska. Cage’s adventures were set in a grungier, more crime-dominated New York City than that inhabited by other Marvel superheroes of the time. The series was retitled Luke Cage, Power Man with issue #17.
As the Blaxploitation genre’s popularity faded, Cage became unable to support his own series and was paired with another superhero whose popularity was based on a declining film genre, the martial arts hero Iron Fist, in an effort to save both characters from cancellation. Though the series title would remain Power Man in the indicia for a while longer, with issue #50 (April 1978) the cover title became Power Man and Iron Fist. It would remain thus until the series’s cancellation with issue #125 (September 1986). The series’s final writer, James Owsley, attempted to shed Cage’s Blaxploitation roots by giving him a larger vocabulary and reducing usage of his catchphrase, “Sweet Christmas!”.
