How would you like to see certain Batman villain go out? Death, Imprisoned forever, Cured of their impulses/insanity, Just keep appearing, other suggestions?
I watch the Batman:Hush movie and I kind of like how Riddler went out spoilers:end of spoilers which reminded me of the Dark Knight Returns with Batman killing Joker.
Him coming out with a master plan and almost wins, Catwoman letting him fall to his death believing shes saving Batman thus breaking her and Batman up
Joker I think should go out in a comical/ironic way like slipping on a banana peel to his death in the Batman Beyond movie or at least on live television.
