Lena Luthor is the sister of Lex Luthor. In spite of her family relationship, Lena frequently associates herself with the Superman Family, mainly as an ally of Supergirl. In the Pre-Crisis continuity, her family had their names changed out of shame and a desire to distance themselves from the name Lex Luthor. Lena became known as Lena Thorul. She married Jeff Colby and had a son, Val Colby. Post-Crisis, she had a daughter named Lori.
