Instead of Joker being a character.. He's changed to just a small cameo.. Harley Quinn becomes a minor character instead.. The orginal one, not the Suicide Squad one..
Blackhat reveals to be working with Ogdan. Who expresses annoyance at Ganger's failure. Black Hat said "no worry, I have one more client".
Said client reveals to be Mark Hamill's JOKER. Black Hat revealed to have captured Robin for him in that scene of RETURN OF JOKER. Black Hat said he needs Joker to join him in return. But Joker said he's busy, and gives Black Hat Harley Quienn instead. Who's in costume.
She expresses fear, even more than of Joker. But Joker says that because of her fan favoritism, he garentee's that nothing bad will happen to her.
Harley reluntaly goes with Black Hat.
"Joker, just make sure you don't die before I return." Black Hat said.
"Don't worry, I won't" Joker promised.
40 MINUTES LATER:
In that infamish scene of JOKER RETURNS (which I have not actually scene, just the part), Joker reveals he preformed various experiments on Robin, who's just a little kid at the time. And drove Robin insane. Into a "little joker".. A scene even Mark Hamill ("the" voice of Joker) expressed uncomfort about. Yet he seemed to have no problem portraying Joker as abusive to Harley, so speaks volume..
Anyway, Joker tells "little Joker" to kill Batman. But instead he kills Joker himself. Shooting him with a "Bang!" Flag Spear Gun. A scene that had to get cut. Though the edited version isn't much better, depending on who you ask. Either way, Joker still dies..
Yeah. One of the biggest "love to hate" villains of all time, straight up "dies" in this film.
