I like! Only played Injustice 1 and read from Year one up to Injustice 1. But we all know Flash (or Supes?) is bound to be OP, so... I propose either banning them or tweaking them so they're not as OP. I'm not proposing to be the GM for this, but I am expressing interest. 

I kinda wanna play John Constantine (I have 0 idea about the guy except magic, which I like), but with false memories. I bet it'd be fun playing a powerful but clueless dude, wondering why he's being hunted down by almost everything.
