League of Assassins

The League of Assassins (sometimes known as the League of Shadows or Society of Shadows in adapted works) is a group of supervillains appearing in American comic books published by DC Comics. The group is depicted as a collective of assassins who work for Ra's al Ghul, an enemy of the superhero Batman. The group appeared in Strange Adventures #215 (December 1968), but did not become officially known as the League of Assassins until Detective Comics #405 (November 1970). The League of Assassins has been adapted into other media several times, predominantly in animated Batman productions, the live-action Batman film series The Dark Knight Trilogy, the CW TV show Arrow, and the Fox TV show Gotham.
