But I think this is because he isnt really trying...

He is always to dandy to go back to Arkham, and dosent mind a loss, as long as he gets his jollys out of it. One example of this is The Killing Joke. I mean, at the end of that book, he pulled out a toy gun, and just laughed when it didnt work. We all know he dosent want to kill Batman, but suppose he wanted to, he would do it in a second. I also have this funny feeling that he and Deadpool would get on very well. Has he ever met Deathstroke?

So. Suppose The Joker decided he had a grand plan (a grand joke) that would shake the DC universes heros and villians, I think he could pull it off. He is always one step ahead of the game, and backing up what I said before, he pretty much intentionally gets thwarted. But if he wanted something enough to stay ahead of the game, then he would pose a greater threat than any other living villian. He is just so crafty and brilliant. Have we ever seen The Joker really push himself? How often is he genuinely (GENUINELY) annoyed for losing? Pretty much never, cause he knows he can just come back for more. 

I dont think we have seen the capacity of The Joker yet.
