My shot in the dark idea of the three Jokers is:Original Joker, Red Hood: the trickster killer. Just as Riddler needs his riddles, this one needs his jokes. His plots have to amuse him and be complicated. This one is with Harley and matches the cartoon.The Comedian: The ruthless killer with a sociopolitical motive. This one is most like The Dark Knight's joker. He kills without jokes, but is trying to make a point.My last one is off the wall, but you never know...The Immortal: Jason, Wonder Woman's brother. This is the one that teams up with the big boys and somehow keeps up. Joker has no powers, why would Superman's enemies team with him? This is why. This one is the one that keeps Batman on his toes in fights, instead of being an easy knockout.
