Detective Comics

Batman
In the late 1950s, Batman stories gradually became more science fiction-oriented, an attempt at mimicking the success of other DC characters that had dabbled in the genre. New characters such as Batwoman, Ace the Bat-Hound, and Bat-Mite were introduced. Batman's adventures often involved odd transformations or bizarre space aliens. In 1960, Batman debuted as a member of the Justice League of America in "The Brave and the Bold" #28 (Feb. 1960), and went on to appear in several Justice League comic series starting later that same year.
