Batman: The Dark Knight #20

Batman strains against an unseen force on Ethan Van Sciver's striking cover, his clawed gauntlet reaching desperately upward while figures trapped inside what appears to be a massive glass sphere are visible behind him — a vivid visual promise of the Mad Hatter's mind-bending threat. Gregg Hurwitz and Szymon Kudranski continue their New 52 run on the Dark Knight with this 2013 chapter subtitled "Down, Down, Down," and the tagline "Pulled into Darkness by the Mad Hatter" makes the stakes unmistakably clear. It's a compelling setup for fans who enjoy Batman pushed to his psychological limits.
