Silly comic book thoughts (not based on any ‘announcement’ or image released today).
If the modern day Batman was became Ra’s Al Ghul in a similar way to whats happening in the ARROW tv series; he would move the entire League of Assassins to Gotham. They would become Batman Inc. and he’d put at least one member on every street corner.
A week later the Joker would have killed half of them with Joker gas.
…Okay, I’m too tired. Going to bed now.
