2) The Court Of Owls
The Court of Owls are a fairly new creation, but their introduction led to one of the most critically acclaimed Batman stories in years. They’re revealed to be a secret society who rule over Gotham City, dealing in corruption and murder to intimidate their way into wealth and power. The Court employs a breed of highly trained undead assassins known as Talons, wearing owl masks on their faces to disguise their true identities. They try to mentally break Batman, and things get extremely personal when it is revealed that his brother is actually a member of this sinister group.
That’s right, Bruce Wayne is revealed to have a brother he never knew about. While it’s never confirmed that the two are related, the clues certainly point to that being the case. Even if the movies decided to drop that particular plot line, The Court of Owls are the kind of characters who would work well in the DC Extended Universe, especially if their role in the movie resulted in Ben Affleck’s Batman also being pushed to the brink of insanity by them. That gives the actor some strong material to work with, and could make him the first superhero actor to to receive serious awards attention.
