Right now I'm working with the name "Adrian Vincentte" for the Joker. It sounds like a Joker-esk name. What would you named the Joker?

[Hits palm of hand up against head] Why did I not think of that!? 
Harmsway (well everybody), now that we have our "perfect" image of that the Joker should look like in the sequel, let's talk about the Joker's mind. What should he act like? Should he be more like the Joker from the Burton original with more comedy than violence, or be more viloent than comedic.
In my short summery of the Batman sequel, my Joker is made out to be just a confused, gruesome, psychopathic maniac. An FBI profiler working for the Gotham Police Department suggests that he was abused in some kind of way, is probably confused about his sexuality, and takes pleasuse in violence, or that he just doesn't fully understand what he is doing and he can't control it probably due to a mental disorder. I doubt that you will like that idea 
But I really want to see a Joker who is just plain messed up in the next film. Not as much as mine, but when I write, I like to find the extraordinary of the ordinary - to push reality as close as possible without breaking through that thick, but fragile wall into fiction.
I'm not going to lie, I dislike your characterization, partially because it's so untrue to the comics. If you're going to adapt a comic book, keep the spirit of the characters in order. As much as Nolan/Goyer changed the characters around for Begins, he didn't change them like you're changing the Joker. He keeps the essence of the characters intact and really just changes externals to make them fit.
The Joker should never be "confused" - he's a genius, albeit an insane one, similar to Hannibal Lecter. He fully understands what he's doing, but is just really, really twisted. He has to be supreme in that sense. He can't be reduced to just another "crazy murderer" (we have plenty of those in Batman as is, even with Mr. Zsasz, introduced in Begins). Joker has to be the GREATEST of all comic book villains.
I also resent the idea that an FBI profiler would be able to characterize the Joker at all. In the comic books, it's been a problem with the Joker that no therapy works whatsoever. They're not even sure he can be qualified as "insane" (similar to the way that Hannibal Lecter wasn't characterized as a psychopath by those that tried to evaluate him). Even when people do try to figure him out, they end up failing, and hard. He's beyond people's understanding and it should remain that way.
If you're going to give an origin to the Joker character, take a look at THE KILLING JOKE. The roots of the Joker character are best there (wherein, he's an innocent man who has "one bad day" like Batman, and because of the tragedy there gives up on sanity). There we understand that the Joker's madness is more of a rejection of logic, reason, order - because he looks at the world and sees it as one giant joke. He doesn't believe in overlying morals, or justice, or anything. For him, insanity is merely an abdication of sanity. He represents the chaos to Batman's order - and is pretty much unpredictable.
The Joker of BATMAN ESCALATION should hardly resemble Nicholson's Joker (who was a far cry from the disturbing, homicidal maniac of the comics). I want to see a genuine sicko, like he is in THE KILLING JOKE, where he shoots Barbara Gordon (the daughter of Commissioner Gordon) in the spine, and continues to make jokes about it as she's lying there on the floor.
His sense of humor should always be dark and twisted, and mean. Of course, we as the audience, should be able to laugh with him now and then, but he really should be nuts. There's a great scene in the story THE LONG HALLOWEEN where the Joker is about murder an entire crowd in Gotham Square on New Year's Eve, just because this anonymous killer *might* be there among them. That's Jokerish, and downright comedic in a dark way.
He should be a vicious murderer as well, as he was in his initial appearance in the comic books - assassinating important figures in Gotham. He should not shy away from displays of violence. He should be downright scary.
