Suggested by IKnowledge Akiza has a good array of monsters on her side. Quite a few of them are very dangerous like her iconic dragon. Joker is a pretty decent fighter as he’s gone hand to hand against Batman at times. That being said, it’s certainly not enough to beat a dragon and Akiza also possessed telekinetic abilities of her own. That’ll make it very difficult for Joker to approach her at all and he’ll really be kept on the defensive. He just doesn’t have any way to approach her and his attacks won’t get through her bodyguards anyway. Akiza wins.
