Triplicate Girl, Luornu Durgo, showcasing her unique bold, single-colored aspect: one in striking orange, another in deep, rich purple, and the last in pristine white.

Luornu Durgo, codenamed Triplicate Girl, first appeared in Action Comics #276, written by Jerry Siegel. A native of the planet Cargg, she could split into three identical bodies, as could all Carggites, due to the planet Cargg having three suns. She was the daughter of Humre and Silvou Durgo. Her costume consisted of a purple dress, orange cape and belt, and black boots.

She was the fourth hero to join the Legion of Super-Heroes, and its first non-founder member.
