10 Comic Book Characters The Joker Has Killed
1. Himself
If you've ever wondered how the eternal conflict between Batman and the Joker might finally turn out, look no further than Frank Miller's seminal graphic novel, The Dark Knight Returns.
The book sees an aged Bruce Wayne cut his retirement short to recapture his former glory. Back in the cape and cowl for the first time in many years, the Dark Knight attempts to clean up Gotham by taking down threats old and new.
This paves the way for the hero's final battle with his arch-nemesis against a fun fare backdrop. It's a bloody, gritty conflict and it comes to a head when Bats breaks the Joker's back, incapacitating him. Still unwilling to violate his golden no-kill rule, the Caped Crusader would have left it at that if the Joker hadn't finished the job for him.
To frame his mortal enemy for murder, the Joker fatally wounds himself by snapping his own neck. He's probably the only person in the world insane enough to pull something like that off, and as a result, he had the last laugh even in death.
