Society of Shadows (DCAU)

In the Batman: The Animated Series, Ra's' League was also known as The Society of Shadows. It first appeared under the control of a character loosely based on Count Vertigo, simply called Vertigo, who filled a role similar to that of Ebeneezer Darrk. In the comic book series Batman: The Gotham Adventures (based on Batman: The Animated Series), it was revealed that the League of Assassins existed as a separate entity from The League of Shadows (although both groups served Ra's al Ghul). Much like their counterpart in the mainstream DC Universe, this version of the League of Assassins was responsible for the murder of Boston Brand, creating the ghostly hero Deadman (which might make the events canon in the DC animated universe, since Deadman's murder was referenced in that continuity). The Sensei, however, was loyal to Ra's in this continuity. When faced with either living out the last of his years in prison or defying Ra's wishes, he chose instead a third option - suicide.
