Una

Born into the sprawling, universe-shaking chaos of DC's Countdown to Final Crisis, Una made her mark in 2008 under the collaborative vision of Paul Dini, Keith Giffen, and Jim Starlin — a creative trio that signals serious cosmic ambition. Her brief but collector-noted run places her in rarefied company, sharing pages with the likes of Green Lantern, The Flash, The Atom, Mary Batson, and Jimmy Olsen during one of DC's most ambitious Modern Age crossover events. With a key issue already to her name across just six catalogued appearances, Una is the kind of compact, intriguing figure that rewards the deep-diving fan — a rare gem tucked inside a landmark era of DC storytelling.
