The Clown Prince of Crime has yet to make his debut in Gotham City in The Batman canon. In the film, a brief appearance can be seen of Barry Keoghan as someone who is clearly the Joker. With the villain incarcerated and bearing various disfigurements, the film even hints at a history between this Joker and Robert Pattinson’s Batman. But that doesn’t mean Batman has already faced the Joker necessarily, as this criminal hasn’t quite gotten to that point yet.
