"A Batman who laughs is a Batman who always wins."

The mastermind behind Dark Nights- Metal, Scott Snyder, gives you a look inside the most terrifying version of Batman ever! He and superstar artist Jock (Batman- The Black Mirror) kick off a chain of events that makes Dark Nights- Metal seem like child's play.

The Batman Who Laughs not only survived his fight with The Joker at the end of Dark Nights- Metal, but is now enacting a sinister plan across the Multiverse--something both terrifying and oddly familiar. When Bruce Wayne realizes the only way to stop this madman is to kill him, he must consider violating the very rule Batman can't ever break ... the rule that created this insatiable villain--the Batman Who Laughs!

As Bruce begins to deduce that his current life is somehow wrong and that all the mistakes he's made are somehow connected, the Batman Who Laughs unleashes a brand-new evil. Enter one of the most punishing Batmen of the Dark Multiverse- the Grim Knight!
