Uno / Curtis Falconer

Emerging from the mid-nineties DC Universe in the pages of Aztek: The Ultimate Man — one of the era's most inventive launches, courtesy of Grant Morrison and Mark Millar — Uno / Curtis Falconer is a figure whose footprint stretches beyond that cult-favorite series into the pages of JLA itself, where he shares adventures with titans like Wonder Woman, The Flash, and Kyle Rayner's Green Lantern. With appearances across JLA Secret Files and at least one collector-recognized key issue to their name, this character occupies a genuinely intriguing corner of late-nineties DC continuity. Nine catalog appearances may sound modest, but in the company this character keeps, every one of them counts.
