Reminder, too, that the Joker took a direct headshot, among many other ways where any real life person would die or at least suffer sever damage or be paralyzed or need serious rehab, and be absolutely fine almost immediately (within a week in real world time). He can also beat CBPHs in fighting by "surprise" if they arent the older members of the Bat family (Tim Drake is basically the youngest member that can take him). And, his blood and sweat are filled with Joker toxin. There's not really anything you could do to him before he decides to bite off your face or something.
So how many gun shots to the face do you think he could survive? Also was there any in story reason given as to why he survived?
