Hush
Then again, if Reeves decides to go with a different, critically acclaimed Batman story, he could adapt the famous “Hush” arc. The story pits Batman against a mysterious foe, one that seems hellbent on destroying the Caped Crusader from afar. It’s revealed that the bandaged man is known other than Thomas Elliot, a childhood friend to Bruce Wayne who works as sort of a dark mirror to him.
What’s truly great about the “Hush” storyline is how it incorporates just about all of Batman’s major villains, as well as his Bat Family and Superman, in fantastic ways, without overshadowing the main villain. Reeves needs to do something bold in order to set his Batman film apart from previous iterations, and a good way to do that would be to include a villain we’ve never seen before.
Hush is a solid choice because he challenges both Batman and Bruce Wayne in ways that his other villains don’t. It’s not only a strong personal story for the Bat, but also explores the world around him, and with the greater universe around Batman now established, it’s a perfect story for the DCEU to tackle.
