Each issue (with the exception of the book-length final issue) consisted of three unrelated stories written by John Ostrander and/or Del Close. For the most part each issue featured a team of four artists, one of whom would illustrate each of the three stories, the fourth supplying that month's cover (which would bear no, or at most only a thematic, connection to the interior contents). Initially, these duties were meant to rotate among Don Simpson, David Lloyd, Bill Loebs (credited under his full name William Messner-Loebs), and George Freeman, but by issue 13 Freeman, Lloyd and Loebs had all left the series (though Loebs returned for the last two issues). Later issues featured Bill Wray as a regular and such guest artists as Timothy Truman, Joe Orlando and Ty Templeton.
