10 Things You Didn't Know About The Joker

9. And Fought Judge Dredd

The team-up made a lot less sense, but at least they bothered to explain it this time. Batman/Judge Dredd: Die Laughing centred on an accidental dimension jump which sees The Joker's disembodied spirit transported from Gotham to the far-flung future dystopia of Mega City One, where he hangs out with similarly spooky Judge Dredd villains the Dark Judges. In fact they get on so much, that Dredd's most iconic villain - Judge Death - decides to appoint him the fifth Dark Judge. It's quite sweet really. Thankfully his body resides in Gotham still, so he can't cause too much trouble.

At least until he figures out how to possess the bodies of the other Dark Judges, which results in a terrifying hybrid of those already pretty freaky villains and The Joker himself - so the big rictus smile spread over their face, the haunting laugh, all that business. Plus his laugh ends up being superpowered that he can make people's heads explode, which is pretty badass. Again though, it all falls apart when Batman falls through the fame rip in space-time, teams up with Judge Dredd, and sorts everything out.
