The title is the weirdest thing about this. I thought it would actually show Batman literally sick. You know, as in suffering from an illness? Of course, everything seems off model here. I thought it would show him evil like the last one. Well, he's certainly not nice.
I'm really getting into all the points of his costume. The Joker could probably be a tad better. This just didn't seem so unique. It's still fairly well detailed, though. It would make sense to just shoot him.
