Who in your opinion is Batman's deadliest enemy?

[King Laufey]

I would say the Joker he is twisted and maniacal and he is able to push Batman over the edge. I remember a line of his from the Dark Knight movie "You have nothing to threaten me with nothing with all of your strength." I mean that was so surreal because it was true Batman was forced to play Joker's game and he couldn't do anything no matter how strong he was.

Joker is deadly, no doubt about that. However in an all out no holds barred battle i'd have to go with Ra's al ghul. We have not seen him in the Nu52 yet, but if he returns the Bat family could be in real trouble. Look how worked up everyone is just thinking that the Joker knows who's behind the masks, something that Ra's has known for a very long time. He's never exploited that out of respect for Bruce, but if that ever changed i could see that becoming one of the most deadly battles Batman ever faced.

Of all Batman's villains over the years, Joker is the only one who is deadly to ME. Because I might die of boredom if they keep overusing him and running him into the ground.

Lol I wasn't expecting the second part of your post, but I agree.

How do you define "deadly" here? If were talking deadly to Batman himself, Joker is probably one of the rogues he should worry least about...

Joker would kill Batman if Batman doesn't stay on his toes. Once Batman gets lax, he's boring to the Joker, so he'd have no problem offing him.

Batman's greatest enemy is himself due to his extremely difficult nature in fully trusting others.

Along the same line of thinking.His paranoia and narcissism.

Depends on your definition of 'deadliest':

Most likely to kill a Bat? Joker
Highest body count? Ra's
Most likely to kill anyone? Zsasz

Joker and Batman are eachother's Nemesis. They can't live without the other. Joker says this a lot himself everytime Batman escapes death.

I think Bane is the one Batman should be worried about. He has less reason and more strength then any other villain in Gotham. He also broke his back, which is a deadly move on it's own. Batman was just lucky to survive that.

If there was any logic in the comic world: Clayface.

I am quite sure any of them could snap Joker in half easily:

Blockbuster
Solomon Grundy
Killer Croc
Bane

He would literally be dung of diseases. I wouldn't want to imagine that bile going through Bats' throat.
