Batman: Legends of the Dark Knight, often simply Legends of the Dark Knight (LotDK) is the name of several DC comic books featuring Batman. The original series launched in 1989 as the third major monthly Batman title, following the popularity of Tim Burton's Batman film. Many of the stories follow the tone of Frank Miller's Batman: Year One. The series differs from other Batman titles of the time. The creative team rotated with every story arc and the stories stood alone, unlike the inter-connected nature of other Batman comics. Initially the title ran stories contained to five issues, often with more mature topics and sensibilities than the other Batman titles. After issue 20, the number of issues for each story began to vary and occasionally tied into crossover events.
