Der Fledermaus

Der Fledermaus made a quiet but distinctive entrance into the DC Universe with a debut in Who's Who: Update '87 — that beloved Copper Age reference series that felt like a collector's bible — before turning up in Young All-Stars, DC's wartime ensemble book that brought together some wonderfully eclectic heroic figures. With only a handful of catalogued appearances, this is a rare, blink-and-you'll-miss-it character who shares pages with luminaries like Green Lantern, Rex Tyler, and Johnny Quick, placing them squarely in the company of DC's Golden Age legacy. For the dedicated completist, Der Fledermaus is exactly the kind of obscure gem that makes deep-diving into late-'80s DC such a rewarding treasure hunt.
