Detective Comics (1937)
Batman was first introduced in Detective Comics #27. At the time, Detective Comics was an anthology, but eventually the Dark Knight took over and the series become solely dedicated to stories of the Batman. While many Batman spin-offs come and go, the self-titled series and Detective Comics are the two mainstays that will never fade away. While the Batman series is designed as the more action-oriented comic, Detective Comics focuses on mysteries and the Dark Knight's detective work.
