Lydda Jath

Lydda Jath, known as Night Girl, is a native of the planet Kathoon who gained tremendous super-strength in darkness thanks to artificial treatments devised by her scientist father, then traveled to Earth to seek membership in the Legion of Super-Heroes.

Born from the Silver Age imagination of Edmond Hamilton and John Forte, Lydda Jath made her debut in Adventure Comics #306 in 1963 and has been a distinctive presence in DC's far-future corner of the universe for over five decades. Her catalog footprint spans from the early 1960s all the way to 2017, with two key collector issues marking her significance along the way — a quiet but meaningful legacy. She keeps remarkable company, sharing pages with luminaries like Rokk Krinn, Cosmic Boy, Imra Ardeen, Saturn Girl, and Night Girl, placing her squarely in the rich, star-spanning tradition of DC's Legion-adjacent storytelling. Whether you're encountering her in the pages of Adventure Comics, the dedicated Cosmic Boy series, or catalogued among DC's finest in Who's Who: The Definitive Directory of the DC Universe, Lydda Jath is exactly the kind of Silver Age gem that rewards the curious collector who looks just a little deeper.
