What is martha wayne joker?

In some versions of the Batman comic books and movies, Martha Wayne Joker is a character who is portrayed as an alternate reality version of Bruce Wayne's mother, Martha Wayne, who becomes the Joker instead of her son, Bruce Wayne, becoming Batman. This alternative storyline drastically changes the dynamic between Batman and the Joker, as the roles are reversed and Batman must navigate a world where his own mother is one of his greatest enemies.

This concept was first introduced in the 2011 Flashpoint comic book storyline, which explores an alternate timeline where the Flash travels back in time to save his mother, altering the course of history and creating a world where familiar characters have drastically different roles and relationships. The idea of Martha Wayne becoming the Joker has since been revisited in various other DC Comics stories and adaptations.

Overall, Martha Wayne Joker represents a dark and twisted tale of what could have been, giving readers and viewers a new perspective on the iconic Batman and Joker characters.
