But that's the thing with Joker, he wouldn't exist without Batman and without a corrupt Gotham City
Joker would create a plan that would cause Logan to have to choose between killing him and saving his friends, which is how you stop Wolverine. Joker is not a henchman. Batman has tried explaining that especially in this arc. He is as smart as you, and no matter how close you think you are to the end, he has planned well ahead. Could Logan kill Doom? Yeah sure but would Dr. Doom put himself in a position to catch that final snikt from Logan? Hell no. He's far too smart for that. The same with Joker.
Logan was taken care of in Old Man Logan fairly easily. They didn't need that 40 man roster of villains. They used Mysterio and his illusion shyt. On a man with super human senses. And made him kill all his friends, everyone he ever loved, and all the future generations of X-Men in a few hours.
By Mysterio.
You think Joker wouldnt break Logan spiritually and mentally? To the point where slicing him to ribbons wouldn't matter? Or put himself in a position to be a victim of Logans rage?
Punisher? Joker isn't scared of bullets or death. He'd have something extra special planned for Frank.
Barring a surprise snikt? No.
Joker is the ultimate example of character/plot armor. I'm having a hard time thinking of any other character in fiction who is more protected.
