The Joker is in the city. Some of you might know who he is, some of you might not. Different worlds make it hard to tell. He is
dangerous. It doesn't matter if he's not immortal, or wielding massive super-human power, be
careful. Oracle knows much more about him than I do, and she'll probably be updating us shortly. In the mean time, watch out for him. I'd rather we take him down fast, but with minimal injury in the process.
