Karl Courtney

Karl Courtney stepped into the DC Universe in 1986 with a debut in Who's Who: The Definitive Directory of the DC Universe — essentially a hall-of-fame entry right out of the gate, rubbing shoulders in those pages with the likes of Captain Cold, The Flash, and Roger Hayden. Across a span stretching into 2020, this Copper and Modern Age figure has turned up in corners of the DC world ranging from Batman to Wonder Woman '77, a quietly eclectic trail for a character with a modest but persistent presence. Three catalog appearances may be a slim count, but in a universe this vast, longevity itself is a credential worth respecting.
