Looks like JL fans will have to deal with Snyder's Joker boner in the future. He has said that he has plans for the Dark Knights post Metal and thanked fans for supporting creation of "new characters" like the Batman Who Laughs which translates to him just keeping that guy.
Also guys one day I'm gonna create a new character named the Nightwing who drugs who'll basically be Dick with venom tubes attached to him. What an original new character right? or how about the Robin who flips a coin? ingenious... oh oh here's a cool one, the Batgirl who riddles eureka.
