The Untold Legend of the Batman is a three-issue Batman comic book miniseries published by DC Comics in 1980. It was written by Len Wein. The first issue was penciled by John Byrne and inked by Jim Aparo. The second and third issues were drawn entirely by Aparo. José Luis García-López drew the covers for the entire series. The primary plot elements of the story are retellings of the origins of several Batman characters. It is the second miniseries published by DC Comics as well as the first starring Batman.
In 1989, as a marketing tool, each issue of the series was available in a special "MPI Audio Edition", accompanied by an audio cassette containing a performance of the text of the issue, with musical cues.
In June 1989, the series was reprinted and packaged with an audio cassette tape that included the story. The issues were smaller than standard DC comic books, at nine inches tall and six inches wide. Inside the front and back covers of each issue were black-and-white reprints of classic Batman covers, with a caption of "Great Moments in Batman's History". The covers included Batman #104, 107, 109, 110, 113 and 120. The second and third issues had more of these on the last few pages of the issues, including Batman #9, 11, 20 and Detective Comics # 27 and 38.
All issues featured the original theme song "Batman, True Avenger" composed by Scott Thomas Canfield.
The series was also reprinted as a single 160-page paperback. That same year, the series was reprinted in smaller format as a premium for Batman breakfast cereal.
