"Year One" later referred to as "Batman: Year One" is an American comic book story arc published by DC Comics, which recounts the superhero Batman's first year as a crime-fighter. It was written by Frank Miller, illustrated by David Mazzucchelli, colored by Richmond Lewis, and lettered by Todd Klein. Batman: Year One originally appeared in issues #404–407 of the comic book title Batman in 1987. As well as recounting Batman's early crime fighting career, the story simultaneously examines the life of recently transferred officer James Gordon - eventually building towards their partnership.
There have been several reprints of the story: a hardcover, multiple trade paperback editions (one in standard comics paper with simpler coloring and one deluxe version with rich detailing in the colors — both colored by Richmond Lewis) and it has been included in The Complete Frank Miller Batman hardcover. The story arc was adapted into an animated feature in 2011.
