Plot

'Who are the Secret Six?' part three! Is Superman the newest member of the Batman Who Laughs' Secret Six? It certainly looks that way, and Batman may be powerless to stop the Man of Steel and his own demented doppelgänger. The Dark Multiverse's most dangerous Bruce Wayne is loose in our world, and he has our world's greatest superhero at his side. Who do you turn to when there's no one to trust?"
