10 Most Heroic Things The Joker Has Done

10. Turning On The Black Glove

Villain team-ups are unpredictable at the best of times, as you've always the chance that these unpredictable bastions of evil will turn on each other instead of the superhero they are supposed to be opposing, totally undermining the entire purpose of teaming up.

With a villain as unpredictable as the Joker, too, the chances of this happening skyrocket. This would serve to explain why the Laughing Prince decides to suddenly break his ties with the Black Glove, sabotaging their plans by allowing Batman to override the security locks on Arkham Asylum, trapping the members of the Glove inside.

The villainous dinner party does technically provoke Joker into this - by refusing to let him bet with the rest of the organisation - but there's also a strong implication that The Pale Man has been setting up his nemesis to beat the villains all along. How so? He avoids initially fighting Batman because his 'nails are still drying', which is up there with 'I'm walking my goldfish' in terms of weak excuses.
