Mad Hatter

Few corners of Gotham's rogues' gallery carry quite the unsettling charm of this Mad Hatter, who stepped onto the scene in 1987's Detective Comics #573 — a Copper Age debut crafted by the celebrated team of Mike W. Barr and Alan Davis. Over nearly four decades of DC storytelling, this version has haunted the pages of Batman, Detective Comics, and even the delightful Batman: Li'l Gotham, proving remarkably durable across shifting eras of the medium. The company is always dangerous and electric: Two-Face, the Riddler, Jonathan Crane, and Robin all share the stage across these 57 catalog appearances, placing Mad Hatter squarely in the thick of Gotham's most iconic drama. With two key issues to their name and a publishing run stretching to 2026, this is a character whose place in the Batman mythos rewards the collector willing to dig in.
