Interestingly enough, when the Joker was created, he wasn’t supposed to be a continuous character. Bob Kane feared that keeping the Joker alive would make Batman look inept as a hero and had the caped crusader dispose of him.

Before the first official Batman was published, editor Whitney Ellsworth overruled Kane and forced him to add a panel showing that the character survived. The villain would go on to appear in nine of Batman’s first twelve issues.
