Moon Knight received his first ongoing series in 1980, with Doug Moench and Bill Sienkiewicz as its main creative team. The character received a complete origin story, and most of his notable recurring villains were introduced, particularly his arch enemy Bushman. Early sales were good for the book, leading to Marvel, as of issue #15, moving the title from newsstand distribution and making it one of its flagship titles for a group of books only available in comic shops. A companion mini-series was also released, "Moon Knight: Special Edition", which reprinted the "Hulk" and "Marvel Preview" Moon Knight stories in color and in comic format, as opposed to their original magazine format. Sienkiewicz left the series after issue #30, though continued to contribute covers until the final issue (#38).
