With the arrival of John Byrne onto the title, Moon Knight was written out of the West Coast Avengers and after a guest spot in "Punisher Annual" #2 (part of the "Atlantis Attacks" storyline), the character was given a new ongoing title in 1989, "Marc Spector: Moon Knight". The series was originally written by Chuck Dixon, who left the title after issue #24. Dixon left the book with several storylines unresolved (most notably, the fate of Moon Knight's errant sidekick, the second Midnight) and the plotline with the sidekick was resolved in the pages of "The Amazing Spider-Man" #353–358, written by Al Milgrom.
