In the third game, if Joker does die, Harley can become a main villian, that she becomes more crazy, that she is more ruthless than the Joker If Scarecrow isn't in the game, he would be a new villain, but if he is in the game, he probably voiced by Corey Burton, since Dino isn't back The al Ghul's family can come back and work their skills again Maybe a co-op with two players, any from the 2nd game Maybe the Underworld can make an appearance, like mob bosses
