Arnold Wesker

Few characters in Batman's rogues gallery carry quite the eerie, unsettling charm of Arnold Wesker, who first crept onto the scene in Detective Comics #583 in 1988, the product of the legendary creative team of John Wagner, Alan Grant, and Norm Breyfogle — architects of some of the Copper Age's most memorable Dark Knight stories. Over nearly four decades of publication, Wesker has carved out a quietly persistent corner of Gotham's underworld, appearing across Batman, Detective Comics, and Batman: Arkham Unhinged, with at least one collector-significant key issue to his name. He keeps genuinely dangerous company — sharing pages with the likes of Two-Face, the Joker, Robin, and Edward Nigma — which tells you everything about the weight DC places on him as a fixture of Batman's world. For fans who love the stranger, more psychologically layered corners of the Batman mythos, Wesker is absolutely worth seeking out.
