10 Batman Questions That Always Confused You

5. Why Is The Joker So Different Each Time?

Comic book characters are interpreted and reinterpreted in different ways all the time. It's partially why Batman is such a divisive character, as he's different things to different people. Naturally, this principle also applies to his villains, but none more so than the Clown Prince of Crime himself, Joker.

If you hadn't noticed already, there are a lot of different versions of the Joker. In some incarnations he's a clowning pranksters, others a sadistic serial killer, and in some a figure who couldn't bear the thought of killing Batman. It's part and parcel of the character, but one that was explained by Grant Morrison back during his stint on Batman in the late noughties.

During his series, Morrison opined that the Joker isn't insane, but rather "super-sane," able to reinvent his personality at the flick of a switch. It explained how the character kept on changing, and provided a canonical precedent for future writers to experiment with drastically different versions of the character.

Now, though, a different explanation has come around, courtesy of Geoff Johns. He gave the Dark Knight access to Metron's chair - a source of limitless knowledge - and revealed that there have been three Jokers all along. Three princes, three tricksters - three distinct eras of the same character.

Johns promises to elaborate this theory further later in the year with Three Jokers, but for now, the reason for how Joker keeps surviving and changing is down to the fact there've been at least three of them.
