Re: In hindsight what changes would you do
^ That could work in the sense that TDK Joker was argueably most similarities to Joker in The Dark Knight Returns.
They both wear red lipstick.
They both laugh very sparingly when compared to Joker in other comics or mediums. But when they do laugh... boy is it creepy.
They both have a creepy assumed relationship with Batman, " You complete me."
Heath's Joker was inspired by many different interperatations, but DTR is very evident among them. I also loved Jokers all white suit in that.
