Now time for me 2 ramble about different versions of u have never heard of. - Batman Ninja joker. Or "Lord Joker" as known in the movie. The movie is literally all over the place, but has major jojo vibes 2 it - Emperor Joker. Never finished the series but still pretty good lmao - Martha wayne. In an AU where Bruce dies and his mother becomes the mother...interesting -The laughing man. Literally the scariest in my opinion- ehdsnofdjios
