Julian Day

Julian Day has been a fixture of DC's darker corners since his 1985 Bronze Age debut in Who's Who: The Definitive Directory of the DC Universe, the series that codified the publisher's rich mythology — fitting company for a character who would go on to share pages with Batman, Bruce Wayne, Robin, Catwoman, and Selina Kyle across four decades of Gotham storytelling. With 58 catalog appearances spread across Detective Comics, Batman, and Batman / Superman, Day has proven himself a quietly enduring presence in the World's Greatest Detective's world, with two key issues among his credits to catch a collector's eye. That kind of longevity — running from 1985 all the way into 2026 — speaks to a character who has genuinely earned his place in the DC canon rather than merely borrowed it.
