Every superhero franchise is kind of in a Catch-22. You need a great, memorable archenemy, or even better, more than one. And you need to be able to bring him back again and again and again. But if a villain like, say, the Joker, has been out killing people for 70 years, doesn't that make Batman look a little incompetent? What kind of superhero lets somebody like the Joker keep slipping away?
How We Almost Lost Him:
That was what writer Bill Finger was wondering. Finger, who wrote the first Batman stories, thought that if Batman's foes kept coming back, it would make him a pretty lousy crime fighter. Take a guess what happened to the Joker in his first appearance in Batman #1.
He uses playing cards. We get it.
