Gotham City Community

A riddle: My enemy is the Joker, I'm black and I help to save Gotham City. Who I'm?

Hello, I am new here. Someone told me about this corrupted website. After reading people's posts, I can determine that this place is full of weird and dumb people. There's a depressed Korean person, a bunch of Gotham city fanatics, and a K-pop stan. Very interesting. I would like it to be known that I love to cause drama. Let the fun and games begin. Ha, ha.
