One of the many differences I found between the two characters is how much of a badass Bane is. I'm constantly going "God damn, that's badass." He's the ultimate brains and brawn mastermind kind of villain. Jokers a deep "too cool for school" villain.
Both characters are great and I thought this was a funny idea. Bane really did complete Joker's goal to throw the entire city into chaos and this popped up in my head
