The depicted subject bears the likeness of Triplicate Girl from the DC Comics; however, the DCAU character was never named on-screen, or otherwise. The title of this article is conjecture based on the character's likeness.
Luornu Durgo is Triplicate Girl, who had the ability to split into three fully operational duplicates. They all had an unrequited crush on Supergirl. After one of the duplicates was killed by Computo, she renamed herself Duo Damsel. The other duplicate was killed too, and she goes by the name Una now in the mainstream continuity. In other versions, she lives on as Triplicate Girl or Triad.
