	The Batman Who Laughs isn’t finished playing with DC’s superheroes yet. This alternate reality version of Batman was first introduced in the successful comic book miniseries Dark Nights: Metal as a Batman who has become transformed into an immoral villain through exposure to Joker toxin. Not only will this version of Bruce Wayne continue to terrorize the DC Universe with a previously unannounced extension to his current miniseries, but he’ll also be the threat at the center of an all-new Batman and Superman team-up comic book series launching in August.
