“A Batman who laughs is a Batman who always wins.” Left rattled by the events of DARK METAL, Bruce Wayne must come face to face with the nightmares spawned from the Dark Multiverse. But even though evil devoured evil in the collapse of Challengers Mountain, the Dark Knight still has his doubts. He discovers that the Batman Who Laughs not only survived the fight with The Joker at the end of METAL, but now he is enacting a sinister plan across the Multiverse—something both terrifying and oddly familiar. But when Bruce Wayne realizes the only way to stop this madman is to kill him, he must consider violating the very rule Batman won’t break…the same rule that created this insatiable villain—the Batman Who Laughs!

After the shocking ending of issue #1, a ticking clock sets Batman on a trail throughout the different realities of the Multiverse. He starts to see all the iterations of his life, and what could have been…but more importantly, Bruce Wayne begins to deduce that his current life is somehow wrong, and that all the mistakes he’s made are somehow connected. Meanwhile, the Batman Who Laughs raises the curtain on his second act, pulling out the big guns to break into Arkham Asylum…enter one of the most punishing Batmen of the Dark the Grim Knight!

All the pieces are starting to fit together as the Batman Who Laughs acquires another key element in his plan—one that is linked to the founding fathers of Gotham City and to a legacy started by the Wayne family and protected by none other than Oswald Cobblepot. While the Penguin goes head-to-head with the darkest version of his mortal enemy, Batman is forced to compromise his principles and purge the serum that protects his heart from the deadly Joker Toxin! It’s a no-win situation as writer Scott Snyder and artist Jock return to the sociopath they created in “Black Mirror”: James Gordon Jr.
