10 Most Heroic Things The Joker Has Done
1. Joker Saves The World
With the Batman vs. Batman drama of the Who Laughs series being so spectacular, the surprisingly well-intentioned efforts of the Joker can easily go overlooked.
As, through the comic, Joker pretty much continually risks his life trying to help save the world - purposefully infecting Batman with his blood in such a way that he gives the Dark Knight maximum time to fight The Batman Who Laughs with the benefits the Joker's blood affords him.
Similarly, it's the Clown Prince who comes to help his heroic counterpart in his final fight, providing Bruce with the much-needed assistance he requires to defeat his evil alternate self.
All jokes about only saving the world to fight Batman more aside, the clown does willingly put his every effort into defending his universe and those within it. How could he not be considered heroic?
