The Pre-Crisis Luthor also has a niece named Nasthalthia Luthor, the child of an older unnamed sister of Lex's who had run away and eloped in Europe when she was a teenager. "Nasty" Luthor is an occasional thorn in Supergirl's side, at one point forming a gang called Nasty's Nasties. Nasthalthia is removed from canon following the reboot of Crisis on Infinite Earths, but does appear in the critically acclaimed All-Star Superman.
