Alright... understandable... these elements will be instilled into the new joker from the toxin....
As you have seen all of Scarecrows "patients" don't come out the same. We can assume after the "high" came down he inherented multiple personality disorder.
Pretend the toxin was the straw the broke the camel's back.
I am sure they will do a lovely job of a new adaptation on the joker.
Right, but you're going in without knowing anything. I'm going in knowing 60 + years of Joker history, and I've ALREADY read a leaked pink script ("Final" versions are in Pink) to where I know how his character is, and what they make him to be. It's not in any way any form of Joker that has ever been seen. I've read psychopathic joker that just kills for no reason. I've read Joker that just plays practical jokes and hurts no one. I've read Joker where he's down and gritty, avenging people close to him. I've read Joker where he's given powers only gods can imagine and how that effected his personality. I've read Joker where all he wanted to do was make Batman smile and laugh, and once he did that he was WILLING GOING TO GO BACK TO JAIL.
The main point is, it's ALWAYS the same guy. Theres no 'set' origin on The Joker, as it's been told so many times, and there never really was a "this is who he was before he was the joker", but it all draws from the same thing. He was a guy that got dumped in the chem waste because of Batman, which made his wife and unborn child leave him, snapping him mentally. Blaming Batman for it he trys to get his revenge. It was said best in the mini 'arkhan asylum': "The Joker is the most bizzare case I've ever encountered. One day he wakes up and is just a normal, happy, fun-loving clown. The next he wants to murder all the jews to quote unquote finish what Hitler started. The next he wants to run a puppy store and sell happiness to little kids, and after he wakes up again he wants to squeeze the little kids heads off".
