10 Comics Secrets We Still Can't Explain

10. The Mystery Of The Three Jokers

In the DC Universe's comics, there's one mystery that has only gotten harder to uncover as time goes by, and it's all about the Joker. Canonically, the Joker's backstory and identity have never been revealed, though The Killing Joke did offer one possible origin story.

In 2015, Batman got a chance to sit in the Mobius Chair, and the first thing he asked was, "What's the Joker's true name?" It wasn't revealed right away, and the following year, Justice League #50 revealed that the answer wasn't simple; there were, in fact, three Jokers.

That revelation stunned the fandom, and Geoff Johns' telling of the Joker and his identity remained a mysterious point of contention among fans. Who were these three Jokers? Is it a metaphor, or multiple identities? There's no way of knowing, and for five years, the fans have been left wondering.

Theoretically, the answer to this mystery will finally be revealed on November 10, 2020. That's the release date for Johns and Jason Fabok's Batman: Three Jokers. The book is set to release three decades after The Killing Joke, and it will examine the who, what, and why of the Joker.
